FR2819795A1 - Roller panel for multidirectional accumulator conveyor has panel supported in four feet to allow movement when driven by belt - Google Patents

Abstract

The roller panel for a multidirectional accumulator conveyor has a panel (1) supported by four feet (2) in which are mounted four freely pivoting wheels (3). The panels are fed by a belt (8) laterally in an offset seating (9). The seating can deviate from the natural path of movement of the belt. The wheels can be driven by friction during movement of the belt.

L'invention concerne le système d'entraînement du plateau roulant dans différentes directions pour être amené avec ou sans précision dans des postes de travaux divers manuels ou automatisés. Rolling workpiece carriers, with accumulation, for multidirectional conveying

The invention relates to the drive system of the rolling platform in different directions to be brought with or without precision in various manual or automated work stations.

 These so-called rolling trays being driven by a dynamic system that does not stop despite the immobilization of the tray (s) at various work stations.

 These installations find their use especially in transfers for the assembly of parts of series for the automobile, the household appliances, the computer or electrical material, etc ...

Due to the geometrical diversity of the path of the rolling platforms,! he changes of direction of these platforms are essential to circulate, to position themselves at the various stations of a manual or automated line, or / and
To switch and circulate on other lines, or / and To release the so-called feed flow from the rolling platforms to the so-called transit traffic at workstations commonly called in line or out line)), or / and For connect to various storage or garage station stores
Finally, to respond to the great flexibility of the routing of the platforms through the invention of the drive of its rolling platforms.

La Figure (1) est la vue de face et de dessus d'un plateau roulant pour comprendre l'environnement du plateau et de la courroie sur ses poulies. The accompanying drawings illustrate the invention in the following description

Figure (1) is the front and top view of a rolling platform to understand the environment of the platform and the belt on its pulleys.

Figure (2) is the current section of one of the 4 feet of the swivel casters to understand the rolling system
Figure (3) is the top view without tray to understand the guidance and circulation systems.

 Figure (4) is the common view of the outer side faces of one of the 4 feet forming the subject of the invention of the drive system of the rolling platforms.

 Figure (5) is the top view of the diversity of the path of the rolling platforms.

 Figure (6) is the top view of the return of the rolling trays.

 The square feet (2) -fig 1- are fixed to the 4 corners of a prismatic plate (1)! These feet have idler wheels (3) -fig. 2- rolling, on the table (4).

 The 4 crazy wheels (3) -fig. 2- are mounted free pivoting (5) as commonly called a {supermarket} cart.

Guides (6) on the belt side channel the movement of the assembly (1 - 2-3-5)
Guides (6) -fig. 3-may have interruptions for a change of direction from longitudinal axis XX to transverse YY. The plate is positioned on a retractable damper stop (12) to be transferred in good conditions. Other guides (7) then take over from the guides (6).

 In the drawing-fig. 4-we show the drive system. A belt (8) stretched between 2 motorized pulleys (11) -fig. 1 and 5-has only longitudinal natural forces along the arrows XX.

appellerons effort de tension F 3 These forces are a function of the tension of the belt (8). We

we will call tension effort F 3

Les pieds (2)-fig. 4-ont une encoche (9) sur chaque face extérieure latérale de la taille de la courroie (8).

The feet (2) -fig. 4-have a notch (9) on each lateral outer face of the size of the belt (8).

 This notch (9) -fig. 4- is offset by a value A between its input and its output and causes residual static friction forces according to the arrows Z which we will call effort Z, naturally causing one or more of the four feet (2) to be trained, thus as dynamic friction allowing the rolling platform (1) to stop on a stop (12).

 The traction force of the rolling plates is by deduction the relation between the material of the foot (2) and the belt (8) called physically coefficient of friction ", given by the reaction of the tension of the belt and the shift of the value A and in the appropriate shape of the notch (9).

 The drive is then carried out between one or more of the four feet (2) and the belt (8) without an auxiliary spring system, in a static manner by the residual effect of the stress given to the belt (8) in its offset Z M.

La-fig 5-explains the paths of the rolling platform (1) on these different stations:
REPA: so-called in-line feed flow)) return with a belt.

REPB return of the rolling platforms (see also-fig 6-)
REPC manual or automated cell out line
REPD manual or automated cell out line "
La-fig 5-explains the transfers of rolling trays on files XX or YY or ZZ through.

Transfers from line XX to line YY are driven by an animated scraper system, forcing the rolling platforms to change direction.

The rolling plates (1) -fig 6-are channeled one by one by one, for the return, by the square feet (2) in the circular guide (13) and driven by the plate (14) which can be engaged by the pulley (15 ) and driven by the belt (8). The belt (8) is diverted by two smooth pulleys (16) and is interconnected by two pulleys with offset grooves (11 or 15).
