Abstract

The support consists of a base (2) onto which are mounted sections (3,4,5), each made up of tilting and sliding parts (6,7), which in their first position are in an upright configuration. The machine is mounted to the top of these supports. In the second position, the supports (4,5,6) are folded at right angles to each other so that the machine is contained within the space enclosed by the supports

Description

The present invention relates to a machine support device of the foot type to which it is attached, which has the particularity of being folded around the frame of said machine. This provides a considerable reduction in volume particularly interesting for transport, and / or when machine must be packed before shipment.

The foot folded around the frame provides more protection last which is an additional advantage during transport.

Although the invention can be applied to many types of machines, when they present or are part of a parallelepiped-shaped volumetric perimeter, the device shown will preferably be used with a quilted padding machine, and this example will be used exclusively in the rest of the description for the sake of simplification and clarity of explanations.

Such machines operate in a succession of stages from a paper-type web-like raw material, the lateral edges of which are folded on itself, before undergoing mainly a crumpling effecting a quilting of the material. The final strip, made from a flat width, therefore has a certain thickness and reliefs due to crumpling, which make it a cushioning product / cushioning able to maintain an object packaged in a carton, a box or more generally any type of box, and to preserve it against possible shocks.

These machines are commonly arranged on supports, feet etc ... to move them between several positions of use or from one location to another, and which are generally dismounted from the machine when it must be transported over a long distance, the support itself then being often dismountable in several separate parts to gain as much volume as possible to the package.

The support of the invention is essentially characterized in that it comprises at least one amount fixed on a base resting on the ground and composed of a plurality of sections adapted to be arranged so as to confer a first vertical configuration to the amount, the machine then being fixed at its upper end, said post further comprising means for folding said sections into a second configuration in which they surround the machine. The realization of the folded configuration of course implies the existence and / or respect of a volume relationship between the dimensions of the machine itself and in particular the volume in which it inscribes, and the different levels of folding provided, it is to say the respective lengths of the sections.

In fact, each section has at its upper part a connection with the element located immediately above it for fixing them in two relative positions, a first position in which the sections are fixed to each other axially, and a second position in which they are fixed perpendicularly after rotation from the first position and in a single direction of rotation.

The folding is done in a sense that is preserved from one section to another to ensure the wrapping of the machine.

Preferably, each section consists of a pair of external and internal profiles, sliding one inside the other so that each section of the pair forms one of the two ends of each section ensuring the mechanical connection with the adjacent element .

These adjacent elements are either another section, and therefore a profile of the other kind, either the machine itself, or the base resting on the ground.

In a possible configuration, it is the outer section which forms the upper end of each section and the inner section which forms the lower end.

To ensure optimum circumvention of the machine volume during folding of the support foot, the profile at the lower end of said foot is directly fixed to the base, without the possibility of relative movements between them, and the profile at the upper end. is provided with a connection to the aforementioned machine with two fixing positions.

In other words, the first folding from the bottom is performed at the top of the first section, and the last folding involves the machine. When actually folding, however, it is of course the reverse order that is respected.

Preferably, the profiles used have a U-shaped whose wall forming the bottom is oriented perpendicular to the axis of rotation of the connection.

In addition, to allow the development of the rotary movement, one of the sides having at least one side wall of the profile is cut at its end involved in the connection, so that the end edge of said profile has two parallel side portions. connected by a portion drawn in the bottom and having a rounding of connection.

This rounded trace, generally an arc of about 90, avoids the contacts between the walls of the two sections during the course of the rotary movement.

Preferably, the cut portion corresponds, in axial dimension and for the external profiles, substantially to the average width of the side walls of the outer and inner profiles.

In this way, when the adjacent sections have pivoted relative to each other, and that the internal section of one has turned in the outer section of the other, it comes to rely on the cut portion of the latter, its outer side wall is substantially at the same level as the uncut end edge of the outer profile.

The mechanical connection for the axial attachment of consecutive sections and their relative pivoting of 90 includes several additional features.

Thus, the bottom of the outer profiles comprises an elongate orifice whose axis is centered in the width of said bottom and whose parallel sides extend towards the end, from the edge of the cut side wall, of one half width side walls of the internal profiles.

This elongate orifice makes it possible, as will be seen in more detail below, to remove one of the sections of the other axially by sliding, to transform an axial sliding connection on three sides into a one-way rotation allowed in one direction. makes the portion cut into a side wall. It is also necessary that the opposite side wall does not hinder the rotation.

This is the purpose of the cut portion, of generally identical shape to that of the outer profile, made at the end internal sections, and in particular the arcuate connecting portion which eliminates any possibility of contact. Said cut portion is substantially equal, in axial dimension and for the internal sections, to the half-width of the bottom of said profiles.

The bottom of the internal sections is provided with a circular hole of axis centered in the width, and located at the edge of cut portion end.

This orifice cooperates in particular for the connection with the external profiles with the elongated orifices which equip the latter, in that they house a rod forming the shaft of rotation of the internal sections with respect to external profiles. Said rod is bolted to said profiles, said bolting being tightened in fixing positions, and loosened for rotation.

It is however necessary to reattach the connection after rotation. For this purpose, the end edge of the internal profiles, at the level of the uncut portion, is provided with a plate fixed perpendicular to the axis of the profile, which is pierced with a threaded orifice.

In addition, the undivided side wall of each outer section is provided with an orifice in front of which is positioned the threaded orifice of said wafer after rotation, said sections then being secured in this position by a screw.

It has been indicated previously that the connection of the end of the upright with the frame of the machine has the double attachment orientation.

For this purpose, said frame of the machine comprises a connecting member with the upper outer profile of the upright which has a profile similar to that of the internal profiles.

According to preferred configuration, the external and internal profiles sliding one inside the other are provided with means for adjusting their relative axial positioning, making it possible to modify the height positioning of the machine.

Preferably, these means consist of a plurality of orifices made at constant length intervals in the internal sections, corresponding to at least two orifices of the external sections allowing at least two connections by bolting in the vicinity of the ends thereof.

More specifically, these two orifices are arranged offset in the width of the bottom of the outer profile and correspond to openings of the inner profile also located on two separate axes of a corresponding distance, the same number of holes on each axis being separated by at least one central oblong hole which can cooperate with orifices situated on the two axes of the external profiles.

The location and number of said orifices on each axis is calculated for the axial connection does not allow all combinations, and in particular that it is not possible to proceed to a fixation in a position in which the outer section is almost completely extracted the external profile, thus considerably weakening the amount: the transverse offset of the holes of the internal profile allows an axial overflow of only about half of one profile relative to the other. Preferably, the support device of the invention comprises two amounts fixed to the machine, located on each side of the volume in which the frame is inscribed.

In this case the openings of the U-shaped sections face each other and the pins forming the axis of rotation are tubes with threaded ends forming a spacer between said uprights. There is then a good transverse rigidity of the entire support.

The base in contact with the ground in this case also has two horizontal sections on which are fixed, towards one longitudinal ends, the lower end profiles of each amount.

According to a preferred configuration, each horizontal section comprises extensions in the form of profiles sliding in it at its two ends, which are each provided near its free end of a wheel. Depending on the weight of the machine, its configuration or its attachment to the amounts, the base of the foot can be readjusted in the direction of increasing the stability of the whole.

Finally, the invention relates to machines for manufacturing quilted padding tape from a raw material in a paper-type web, by folding the lateral edges of the strip on itself, driving and creasing the folded strip, then sectioning the product thus obtained into sections of variable length, machines which are provided with a support device as described above.

We will now describe said support device in more detail, with reference to the accompanying figures for which - Figure 1 shows a device side view according to the invention supporting a padded padding machine manufacturing machine in unfolded vertical position; - Figure 2 shows said device being folded; - Figure 3 shows it completely folded - Figure 4 shows a side view of an external profile; and - Figure 5 illustrates an inner profile, also in side view.

The machine (M) of FIG. 1 comprises an exit tunnel (T) and, at the entrance, a device (D) initiating the folding of the lateral edges of said strip (B) resulting from a roller (R) for storing the continuous strip (B) constituting the raw material. It should be noted that the support device (P) also supporting the reel (S) of the roller (R) comprises two vertical uprights (1) and a base (2) equipping each upright (1). The amount (1) consists mainly of three sections (3, 4 5) each consisting of two sections sliding one into the other. The external profiles are referenced (6) while the similar internal sections of the two sections (4, 5) are referenced (7). These allow a connection to two attachment modes, while the lower inner section (7 ') is simply attached to the base (2).

Said base (2) comprises, at the lower end of each upright (1), a horizontal main section in which slide two end profiles (9, 9 ') to which are fixed wheels (10).

On the base (2) as well as on the upright, the relative positions of the sliding profiles are adjustable by means of bolts (11, 12) cooperating with orifices periodically arranged in at least one of the two sliding profiles.

Their number depends on the size of the profiles (see also Figures 4, 5). Thus, the lower internal section (<B> 7 </ B>), the largest, has seven orifices: three oblong central orifices (13) and, at each end, two round orifices (14, the profiles (7) constituting the following sections (4, 5) have only one oblong central opening (13 ', 13 "), and also two ends (14', 15 ', 14", 15 ") of end. offset in transverse dimension, and are aligned along two longitudinal axes arranged on either side of the median main axis, the orifices (16, 17) formed at the ends of the outer profile being offset by the same distance, it is it is therefore impossible to axially fix the internal section (7, 7 ') in the outer profile (6) at all the positions provided by orifices (13, 14, 15): four steps of 50 mm are possible for the section (3) and two steps only for the upper sections (4, 5), as shown in the figure.

In the lower part of the machine (M), a configuration (18) similar to that of the internal profiles (7) allows the relative positioning machine / external profile (6) of the section (5) in both axial modes and rotated.

Referring to Figure 2, a first rotation is performed between the section (4) and the section (5), and the axis of rotation (19), ie a rod at least partially threaded, is at this point. effect previously positioned at the top of the elongate orifice (20) vertical equipping the external profiles (6) before the rotation is started. The axis (19) passing through an orifice (27) of the inner profile (7), it can then be pivoted to bear on a portion cut in the upper part of the outer profile (6), as well as is explained in particular with reference to Figure 4. The connection is then completed by a screw (21) in a plate (22) welded to one end of the inner section (7) (see Figure 5).

The rotation shaft (1 is additionally also bolted in the axial and pivoted positions, and in reverse deboulonné to allow the passage of one end of the other oblong slot (20) marking the two positions of fixation, and during rotation.

A subsequent rotation between the section (3) and the section (4), and between the section (5) and the machine (M) results in the fully folded configuration of FIG. 3. The base (2) itself is folded in That is, the profiles (9, 9 ') are tucked inside the profile (8). The reel device (S) of the supply reel (R) is folded inside to the sections (4): although only one post (1) appears in side view, the machine is as mentioned equipped with two identical uprights (1) which can accommodate a wire feeder ..

The device (D) initiating the folding of the lateral edges of the band (B) is folded between the wheels (10), while the tunnel (T) is folded in contact with the frame of the machine (M). The latter is therefore contained in the volume defined by the amount (1) folded on their base (2), the external elements such as the tunnel (T), the device (D) or the reel (S) being integrated in a volume slightly larger, taking into account the base (2).

Referring to Figure 4, the outer section (6) has at its upper part a cutout portion (23) integrating over a certain length of the side wall (24) and part of the bottom adjacent the elongate orifice (20). The other side wall (25) has a bore for accommodating the screw (21) for fixing the inner profile (7) in the rotated position (see Figures 2 and 3). The height adjustment holes (16, 17) are offset by the same distance on each side of the longitudinal axis of the U-profile (6).

The inner profile (7) of Figure 5 has a similar configuration, with smaller dimensions since it is housed in the outer section (6). The cut portion (26) is also less important, and located in the vicinity of the orifice (27) housing the rotation shaft (19). A wafer (22) is welded to the lower end having a threaded hole (28) for pivotal attachment.

In the support of the invention, the open parts of the U-shaped sections face each other, and the shafts (1 are common to the two uprights (1), forming at the same time a stiffening strut of the support foot. It is understood that an example of application of the invention is not exhaustive of the invention.On the contrary, the invention encompasses all variants within the reach of those skilled in the art.
