Definitions
- the present invention relates to a device for transporting parts for supplying machines intended to allow the supply of parts to machines, or more generally intended for ensuring all types of transport of parts in industrial processes.
- Conveyor belt devices have drawbacks in terms of their size and therefore cannot be installed in many situations. They can also have certain drawbacks related to the supply of actual parts, that is to say the transition which takes place at the end of the strip between the conveyor belt and the machine supplied.
- the vibrator devices operate on a relatively simple principle which consists in alternately moving the rail axially while taking off the pieces transported in the air during the return to the rear position of the rail.
- these vibrators have oscillating movements with a vertical component intended to take off the parts and horizontal components for the axial movement of the rail. In this way, the parts remain in contact with the rail only during its axial movement forward.
- these vibrating rails have many drawbacks linked to their design and their use. In fact, they do not allow parts to be transported at high speeds and are therefore limited for certain applications. In addition, certain parts intended to be transported are fragile and are therefore liable to be damaged during their movement along the rail by the repetition of shocks due to the vertical oscillations of said rail.
- the present invention aims to solve the aforementioned drawbacks of parts supply apparatus using simple, reliable, inexpensive and easy to implement means. It thus offers a parts feed device which allows rapid transport of the parts, capable of operating in both directions, capable of transporting fragile parts and light parts while having a small footprint, which facilitates its adaptation to different situations encountered in industrial processes.
- the parts transport device is of the type comprising a transport member on which are intended to be arranged the parts to be transported, said conveying member being mounted movable relative to the frame of the device to be at least driven by a reciprocating movement, which takes place in the plane in which the parts are transported, by a device drive and it is characterized in that the drive device comprises at least one drive cam, cooperating with at least one roller integral with the transport member, to give it its movement
- the transport member is a longitudinal rail whose movement in the plane of movement of the parts is an alternating translational movement generated by the rotation of the cam training.
- the transport member is a rail of curved, circular or helical shape whose movement in the plane of movement of the parts is an alternating rotational movement generated by the rotation of the drive cam.
- the transport member is carried by a rail support which carries a roller which drives it in translation along the longitudinal axis of movement of the parts when it cooperates with the rotary cam.
- the device for transporting parts of the invention is characterized in that it comprises a motorization device which drives the cam in rotation about its axis of revolution, said rotation of the cam causing, thanks to the specific shape of its contact surface, the alternative longitudinal displacement of the rail support by cooperating with the roller.
- the axis of rotation of the cam and the axis of rotation of the drive roller are parallel.
- the cam has a developed surface curve which comprises a first so-called acceleration zone, very short, then a so-called zone advance where the radius of the cam increases steadily over its angular sector, it then includes a short deceleration zone, before a so-called recoil zone where the radius decreases.
- the advance movement of the rail corresponding to the zones of acceleration, advance and deceleration of the developed surface represents an angular sector of the cam of between 200 ° and 300 ° while that the so-called recoil area represents an angular sector between 60 ° and 160 °.
- the roller and therefore the rail undergo a forward movement corresponding to the acceleration, advance and deceleration zones of the cam during about two thirds of the turn, then a more abrupt movement of recoil during the last third of the turn, this rail movement allows, thanks to the acceleration zone, to bring the rail quickly to the speed of movement relative of the parts (with respect to the frame) to further accelerate them before moving them at constant speed during the advance zone, then to let them slide during braking or deceleration zone, then the retreat of the rail, which takes place quickly before to start the cycle again.
- the rotary cam is controlled by a motorization device which allows its rotation in both directions according to the choice of the user.
- the cam is sandwiched between two rollers, while said cam consists of two superimposed cams, a first cam or upper cam, with which a first roller (6a) cooperates, and a second cam or lower cam, with which a second roller cooperates.
- Figures 1 to 6 illustrate a first embodiment of the parts transport device of the invention.
- Figure 1 shows the device in perspective.
- Figure 2a shows the device in side view.
- FIG. 2b illustrates the device for transporting parts in front view.
- Figure 3 shows an exploded view of the transport device.
- Figure 4 shows in section the rail mechanism.
- FIG. 5 illustrates the pivoting cam from below.
- FIG. 6 schematically represents the contact surface of the developed cam.
- FIG. 7 is a perspective view similar to FIG. 3.
- Figure 8 is a sectional side view.
- Figure 9 is a top view illustration showing the cams and rollers.
- Figure 10 is a perspective view mounting the cams and the rollers.
- the invention relates to a device for transporting parts, bearing the general reference (1), this device is intended for transporting parts (2) for supplying a machine tool or other in the context of an industrial process. It comprises a conveyor member (3) on which the pieces to be transported (2) are arranged, said member being intended to set the pieces in motion in the plane (P) in which they are located, to move them relative to itself. even.
- the conveyor member (3) is movable relative to the frame of the device to be set in motion in the plane (P) by a drive device (DE) comprising at least one cam (4).
- the movement of the conveyor member (3) takes place only in the plane (P) in which the parts (2) are moved.
- the parts (2) are moved on the conveyor member (3) by sliding during the movements of said member.
- the transport member (3) advantageously consists of a longitudinal rail whose movement in the plane ( P) is an alternative translational movement generated by the rotation of the cam (4).
- This movement of reciprocating translation of the rail (3) causes the parts (2) to slide along the rail thanks to the particular configuration of the mechanical parameters (acceleration, speed) of the reciprocating movement obtained thanks to the cam (4) and to the physical parameters of the constituent elements (coefficient of friction). It can be noted that such a device could use a different transport member driven by another type of movement.
- the movement of the transport member is an alternating rotational movement. It is therefore advantageously constituted by a rail of curved, circular or helical shape which is driven by an alternating rotary movement of reduced amplitude, this movement being generated by the rotation of a drive cam similar to that of the first mode of embodiment which cooperates with a slope secured to a circular rail support articulated around a fixed axis.
- the transport rail (3) on which the parts to be transported (2) are arranged is carried by a rail support (5) which carries a roller (6) .
- This roller (6) is mounted on the support (5) in order to be able to drive it in translation along the longitudinal axis (XX ') when it cooperates with the rotary cam (4) as shown in Figures 1, 3 and 4 .
- the parts transport device (1) comprises a motorization device (7) which drives the cam (4) in rotation about its axis of revolution (YY ').
- the rotation of the cam (4) causes, thanks to its specific shape, the alternative longitudinal displacement of the rail support (5) by cooperating with the roller (6).
- the axes of rotation of the cam and the roller are parallel, thus reducing wear due to friction during their cooperation.
- the device could have a different configuration concerning the cooperation of the cam and the rail support.
- the axis of rotation of the cam could be positioned differently while the latter would act on an inclined plane of the support and no longer on a roller, for example.
- this comprises return means intended to urge the roller (6) to keep it permanently in contact with the cam (4) so that the reciprocating movement of the rail (3) corresponds exactly to the developed curve of the surface in contact with the cam (4).
- These return means can be of several types such as being formed by a tension spring (8).
- this spring (8) can act directly between the frame (9) on which the motor (7) and the rail (3) is fixed, while the rail support (5) is slidably mounted on a guide ( 10) of the frame in order to be able to be urged towards the cam (4) via the conveyor rail (3) and the spring (8).
- the cooperation of the rail support (5) with the guide (10) could be carried out more simply by two flexible lateral blades which would ensure the connection between the frame (9) and the vibrating rail (3).
- the parts feed device (1) of the invention is slidably mounted on the frame (9) by means of its support (5) and the guide (10). Its movement is a translational plane movement whose accelerations and decelerations are controlled exclusively by the slope of the external surface or contact surface of the cam (4).
- the cam (4) has a developed surface curve such as that illustrated in FIG. 6.
- it has a first zone (a) called acceleration, very short, representing an angular sector of less than 20 °, then a so-called advance zone (B) during which the rail (3) moves at constant speed, the radius of the cam increasing substantially constantly over a substantially angular sector equal to 220 °, so that the rail moves with low or even zero acceleration.
- a short deceleration zone (C) the angular sector of which is less than 20 °, before a so-called reversing zone (D), recoil which takes place with a strong acceleration, during a first half of the angular sector ( Dl), and with a deceleration, in a second part (D2), before returning to the initial point of the cam.
- the advance movement of the rail corresponding to the zones (A, B, C) represents an angular sector of the cam between 200 ° and 300 ° while the so-called recoil zone (D) is between 60 ° and 160 °.
- all of the zones (A, B, C) represent an angular sector greater than 240 °.
- the slopes of the contact surface of the cam are specifically calculated so that, when the rail (3) recedes suddenly, the parts (2) continue to advance with a relative speed relative to the frame, before being taken up by the rail in the acceleration zone (A) when it reaches their speed.
- the cam has holes for the passage of pins, these holes allowing the exact positioning of said cam on the machine tool with an exact and reproducible positioning of the reference line or point 0 of the cam.
- This cam can also be mounted on the motorization device in a removable manner so that it can be interchangeable, for example, thus allowing the adaptation of the transport device to the different parts and to the different constraints of the powered machines.
- Figures 7 to 10 show a second embodiment of the invention.
- the return means of the first embodiment intended to keep the roller (6) in contact with the cam (4), and constituted by the spring (8), has been replaced by a structure with two rollers. (6a, 6b) and two cams (4a, 4b).
- the cam (4) consists of two superimposed cams. Namely a first cam or upper cam (4a), and a second cam or lower cam (4b).
- the two cams (4a and 4b) are integral and mounted on the 'output shaft of the engine (7).
- the rail support (5) carries two rollers (6a, 6b) intended to cooperate with the cams (4a, 4b). Namely, a first roller (6a) which cooperates with the first cam (4a), and a second roller (6b) which cooperates with the second cam (4b). Consequently, the two rollers are arranged on either side of the two cams and the plane P passing through the center of the rollers passes through the pivot axis (Y, Y ') of the two cams formed.
- the general horizontal plane (Hl) of the first roller is arranged in the horizontal plane general of the first cam
- the general horizontal plane (H2) of the second roller is disposed in the general horizontal plane of the second cam.
- the general horizontal plane (Hl) of the first roller and therefore the general horizontal plane of the first cam is arranged above the general horizontal plane (H2) of the second roller and therefore of the general horizontal plane of the second cam.
- the motorization device which makes it possible to rotate the cam can advantageously operate in both directions. So when the drive cam turns in one direction,
- the motorization device can advantageously allow the speed of rotation of the cam to be adjusted.
- the rail can be covered with a coating whose coefficient of friction is adapted to the range of parts that it is intended to transport.
