Description

Title of the invention: Device for peeling a peelable wedge Domain

[0001] The present invention relates to a device for peeling a peelable wedge.

[0002] A mechanical assembly to be manufactured has manufacturing tolerances. Indeed, each constituent part of the assembly is manufactured according to specific manufacturing ranges, within defined and imposed tolerances so that the assembly of the parts together is feasible.

[0003] The resulting mechanical assembly will also have dimensions that must fall within the specified tolerances. However, the more component parts this mechanical assembly has, the larger its tolerances will be. Thus, once the final assembly is complete, gaps will appear. These gaps must be compensated for so that the resulting mechanical assembly fulfills its function or can itself be assembled with another mechanical assembly.

[0004] The clearances present in the mechanical assembly can vary in size, as their control depends on a significant number of parameters, particularly the manufacturing tolerances of all the constituent parts of the mechanical assembly. For these reasons, it is sometimes not possible to compensate for these clearances using standard shims with standardized dimensions. In such cases, peelable shims are commonly used.

[0005] A peelable shim resembles a solid shim but is made of thin, bonded metal sheets layered one on top of the other. The bond between the sheets is an extremely thin film that undergoes high pressure and heat treatment, resulting in optimal hardening and a virtually zero thickness. By removing the appropriate number of mechanical sheets, an operator can directly adjust the shim to the desired thickness to compensate for any play. The operator simply removes one sheet after another from the peelable shim until the desired thickness is achieved. Removing the sheets is done using a sharp tool, such as a knife or a craft tool, as it is necessary to lift an edge of the sheet in order to remove it.

[0006] The use of such sharp tools raises safety concerns: indeed, certain precautions must be taken to avoid injuries during their use, particularly those resulting from a slip. Safety equipment is therefore mandatory for handling sharp tools without injury. For example, it may be necessary to wear a glove or a reinforced sleeve to protect the operator and prevent injury should the tool slip.

[0007] There is therefore a need to guarantee the safety of the operator while offering him a reliable and quick solution for peeling the peelable wedge. Summary

[0008] An object of the present invention is to resolve all or part of the disadvantages of the prior art mentioned above.

[0009] To this end, the invention relates to a device for peeling a peelable wedge, comprising an approximately parallelepiped-shaped frame with a base, a front partition, two side partitions, a rear partition, a stop fixed to the front partition and having a notch, two lateral guide rails fixed to the side partitions, a platform attached to a portion of the base having an upper surface suitable for receiving the peelable wedge, and a carriage shaped to slide along the two lateral guide rails between a rear and a front position. The carriage is notable in that it comprises: - a structure having a front face and a rear face and composed of two guiding means, each guiding means being fitted into the corresponding guide rail, and of an upper platform, - a knife interposed between the two guiding means, under the upper platform of the structure, placed in contact with the bottom of the chassis, the knife having a proximal end disposed at the rear face of the carriage structure and a sharpened distal end disposed opposite the proximal end, oriented towards the front partition of the chassis, the difference in height between the distal end of the knife and the upper surface of the platform being adjustable.

[0010] An operator places a peelable wedge on the bottom of the frame and adjusts its height so that, once the wedge is peeled, it has exactly the desired height. This device therefore makes it possible to remove, in a single pass, the number of sheets of the peelable wedge necessary to achieve the desired thickness, while ensuring the operator's safety.

[0011] Advantageously, the HP height of the tray is adjustable relative to the bottom of the chassis, the Hu height of the knife being fixed.

[0012] Advantageously, the height HED of the distal end of the knife is adjustable relative to the bottom of the chassis, the height HP of the tray being fixed.

[0013] Advantageously, the trolley includes a means for applying pressure to the peelable wedge attached to the structure of the trolley and capable of exerting vertical pressure on the peelable wedge.

[0014] Advantageously, the pressure means is in the form of a roller driven by the trolley and animated by a rotational movement triggered by the movement of the trolley.

[0015] Advantageously, the carriage includes an adjustment means suitable for adjusting the height difference between the distal end of the knife and the surface of the tray.

[0016] Advantageously, the adjustment means is a worm screw, an adjustable crank or a worm gear.

[0017] Advantageously, the side partitions of the chassis have a graduated inner face.

[0018] Advantageously, the trolley includes a handle.

[0019] The invention also relates to a method for implementing a device for peeling a peelable wedge. This method is remarkable in that it comprises the following steps: - Determining the final height of the wedge, - Calculating the height of the platform, - Adjustment of the height difference between the distal end of the knife and the upper surface of the tray, using the adjustment means, - Positioning the peelable wedge on the platform so that the wedge is inserted into the notch of the stop, - Translation of the carriage from position to position so that the distal end of the knife is inserted between the sheets of the peelable wedge, on a second edge of the peelable wedge, and that the distal end completely detaches the sheets from the wedge, - Translation of the trolley from position to position so as to disengage the trolley from the peelable wedge.

[0020] Other features and advantages of the device according to the invention will become clearer upon reading the following description, which is indicative but not limiting, with reference to the accompanying drawings in which:

[0026] [Fig. 5] represents the block diagram of a method for implementing the device to peel a peelable wedge according to the invention.

[0027] The invention shown in [Fig. 1] relates to a device 1 for peeling a peelable wedge C. The device 1 comprises a frame 2 of approximately parallelepiped shape. The frame 1 comprises a base 2a, a front partition 21, two side partitions 22 and 23, and a rear partition 24.

[0028] The chassis 2 is equipped with two lateral guide rails 6a and 6b. These two guide rails 6a, 6b, parallel to each other, are respectively fixed to the lateral partitions 22 and 23. Finally, a stop 8 is fixed to the front partition 21. The stop 8 has a V-shaped notch 8a suitable for receiving an edge of the peelable wedge C ([Fig. 1a]).

[0029] The stop 8 can be detachable so as to use a stop 8 having a notch shape 8a adapted to the geometry of the peelable wedge C to be peeled.

[0030] The chassis 2 further comprises a platform 4 attached to a portion of the chassis base 2a. The position of the platform 4 is adjustable only in height. This platform 4 is flat so that, when an operator places the calibration mark C on the platform, it is in a horizontal position.

[0031] In a first embodiment, the platform 4 has an upper surface 4S suitable for receiving the peelable wedge C. This surface 4S is positioned at a height HP, calculated with reference to the bottom 2a of the chassis 2. This height is adjusted so that once the wedge C is peeled using the device 1, it has exactly the final height HCP desired by the operator.

[0032] The platform occupies approximately 60% of the surface of the bottom 2a of the chassis 2, and is arranged on the front part of the chassis 2, on the side of the stop 8.

[0033] In this embodiment, the height HP of the platform 4 is adjusted by means of an adjustment means 4a as shown in [Fig. 2]. This adjustment means 4a is capable of adjusting the height HP of the platform 4 so that the wedge C, once peeled, has the final height HCP desired by the operator. A linkage system (not shown in the figures) is located in or under the platform 4 and is actuated when the adjustment means 4a is activated by the operator. This linkage system will not be described in further detail as it is part of the knowledge of those skilled in the art. In the embodiment shown in [Fig. 2], the adjustment means 4a is a worm screw 4L. Depending on the direction of rotation given by the operator, the worm screw 4L will actuate the platform 4 upwards or downwards, in order to adjust the height of the platform 4 to the desired height. However, any other means of adjustment, such as a crank adjustable or a vemier for example, suitable for adjusting the height can be used, without going out of the scope of the invention.

[0034] The inner faces of the side partitions 22 and 23 may have a graduated scale to assist the operator in adjusting the height (HP) of the platform 4. The inner face is defined as the face of partition 22 (respectively 23) that faces partition 23 (respectively 22). The graduated scale is marked with reference to the base 2a of the frame 2.

[0035] The device 1 is also equipped with a carriage 10 shaped to slide along the two guide rails 6a, 6b. The carriage 10 comprises a structure 101 having a front face FAV and a rear face FAR. The structure 101 further consists of two guide means 101a, 101b and an upper plate 101c. The guide means 101a (respectively 101b) is fitted into the corresponding guide rail 6a (respectively 6b) so as to allow the carriage 10 to slide along said rails. The carriage 10 is thus able to slide between a rear position PAR and a front position PAV of the chassis 2 ([Fig. 2]).

[0036] Advantageously, and to facilitate handling, the structure 101 may include a handle 1Old to facilitate handling by the operator. The structure 101 has a front face positioned opposite the front partition 21 of the chassis 2 and a rear face positioned opposite the front face.

[0037] As shown in the cross-sectional view of [Fig.3], the structure 101 of the carriage 10 is further equipped with a knife 102 which is integral with the structure 101 of the carriage 10. The knife 102 is interposed between the two guide means 101a, 101b of said structure. The knife 102 is thus sandwiched between the base 2a of the frame 1, the platform 101c, and the two guide means (101a, 101b) of the structure 101 of the carriage 10. The knife 102 has a proximal end 102a located at the rear face of the structure 101 of the carriage 10 and a distal end 102b located opposite the proximal end, oriented towards the front partition 21 of the frame 2. The distal end 102b of the knife 102 is sharpened so that it can fit between two sheets of the peelable wedge C. This distal end is located at a height HED, calculated with reference to the base 2a of the frame 2. This height HED is known by design.

[0038] The knife 102 is fixed on the structure 101 of the carriage 10. This particular arrangement allows the knife 102 to be removed for replacement or resharpening when it is too worn to be used.

[0039] According to a second embodiment, the platform 4 is fixed, its height not being adjustable. In order to adjust the height of the wedge relative to the desired final height HCE, the adjustment means 4a is used to adjust the height HED of the end distal 102b of knife 2. In this second embodiment, unlike the first embodiment in which the height of knife 102 is not adjustable, it is possible to adjust the height HED of the knife in order to position the distal end 102b at the height necessary to obtain the desired height HCE of wedge C.

[0040] Finally, the structure 101 of the carriage 10 includes a pressure means 101e attached to the structure 101 of the carriage 10. During the sliding of the carriage 10, this pressure means 101e exerts vertical pressure on the wedge C to ensure that said wedge remains in place when the device 1 removes the desired number of sheets. In the embodiment shown in the figures, this pressure means is a roller driven by the carriage 10 and rotated by the movement of said carriage 10.

[0041] A method 20 for implementing device 1 will now be described.

[0042] In a first step El, the operator in charge of peeling the wedge C determines what final height HCE the wedge C must have in order to be able to be installed in a gap present in a mechanical assembly.

[0043] The second step depends on the embodiment variant and is divided into two steps E2a, E2b.

[0044] During the second step E2a corresponding to the first embodiment, the operator calculates the height HP to which the plate 4 must be set so that, once the peeling operation is carried out, the wedge C actually presents the predetermined height HCE from step EL. The height HP of the plate 4 is calculated from the following equation:

[0045] HP = HE D - Hce

[0046] in which:

[0047] HP: tray height 4

[0048] Hed: height of the distal end 102b of knife 102

[0049] Hce: desired height after peeling the wedge C

[0050] According to this step E2a, the operator adjusts the height HP of the platform 4 calculated according to the previous equation (step E3) using the adjustment means 4a. It should be noted that, according to this embodiment, the height Hu of the distal end 102b is fixed.

[0051] In the case of the second embodiment in which the HP height of the plate 4 is fixed, the operator calculates, during step E2b, to what height HED the distal end 102b of the knife 102 must be set so that once the peeling operation is carried out, the wedge C actually has the predetermined height HCE in step EL. The HED height of the distal end 102b is calculated from the following equation:

[0052] Hed = HP + HCE

[0053] in which:

[0054] HP: tray height 4

[0055] Hed: height of the distal end 102b of knife 102

[0056] Hce: desired height after peeling the wedge C

[0057] According to this step E2b, the operator adjusts the HP height of the platform 4 calculated according to the previous equation (step E3) using the adjustment means 4a. It should be noted that, according to this embodiment, the HP height of the platform 4 is fixed.

[0058] The choice of step E2a or E2b is therefore made according to the structure itself of the device 1 for peeling a peelable wedge, that is to say according to the element whose height is adjustable: the first plate 4 or the knife 102. It should be noted that, whatever the variant of the invention, the difference in height between the distal end 102b of the knife 2 and the surface 4S of the plate 4 is adjustable.

[0059] During the next step E4, the operator places the wedge C on the first platform 4 so that the edge B1 of the wedge C fits into the notch 8a of the stop 8. The wedge C is therefore held securely on the device 1, locked in the notch 8a.

[0060] In the next step E5, the operator pushes the carriage 10 so that it translates towards the front partition 21: the carriage 10 then moves from the PAR position to the PAV position. The distal end 102b of the knife 102 then inserts itself between the sheets of the wedge C, on a second edge B2 of the wedge C, detaching them from the sheet below in order to remove the number of sheets necessary to obtain the desired height HCE. The operator pushes the carriage 10 until the distal end 102b of the knife 102 completely detaches the sheets from the wedge C to be removed.

[0061] In certain specific cases, particularly when dealing with a curved wedge, the operator stops the carriage's movement to remove the wedge and complete the operation manually. The movement of the carriage 10 can be stopped either manually by the operator or by adding one or two stops (not shown) positioned in an opening T in each side of the rails 6a, 6b. When the guide means 101a and 101b are in contact with the stops, the carriage 10 can no longer move forward. These stops can, for example, be in the form of pins.

[0062] Finally, during the last step E6, the operator pushes the carriage 10 so that it translates from the PAV position to the PAR position in order to free said carriage from the wedge C. He can then remove the wedge C from the device 1: the wedge C has the correct dimension, in particular the height HCE desired by the operator.

[0063] The advantages of a device 1 for peeling a peelable wedge C are numerous: The sliding of the carriage 10 is controlled by means of the guide rails 6a, 6b, Wedge C is held in place by means of notch 8a and pressure means 101e, Knife 102 is held within structure 101. The operator's safety is ensured: there is no risk of injury when detaching the sheets from the peelable wedge. The procedure for implementing device 1 is quick, the setting of the HP height of the platform being facilitated by the adjustment means 4a.
