Definitions

  • the present invention relates to a method and a device for grouping into stacks of determined dimensions objects, which, like rusks, have the distinction of being flat, fragile, rough and having shapes and dimensions defined with poor tolerances. , especially the thickness.
  • Rusks are made from sandwich loaves cut by sets of parallel blades working automatically. These sets of blades cut the same number of slices from a determined length of bread, but the spacing between two neighboring blades can differ without great inconvenience.
  • a thinner slice will be offset by its larger neighbor. Taking into account the subsequent treatments bringing each slice to the rusk state, the differences in apparent thickness between neighboring slices can reach more than 5 7. However, in practice, the differences compensate for each other and, when the rusks in stacks of fifteen, we find that the lengths of similar stacks placed side by side generally remain less than 2% and that packaging in standard packages is very possible.
  • rusks or objects of the same type are generally presented in contiguous rows on a conveyor such as a conveyor belt or a slide.
  • the objects are arranged on the field perpendicular to the axis of the row. If we then want to select in the row a certain number of objects to constitute a pile of determined length, we realize that we cannot do it by pushing the objects laterally from the row lying on the corresponding length. Most often, the last of the objects selected from the head of the row and the first of those remaining in the row do not slide relative to each other, but break due to their great, fragile, unless you take special precautions.
  • the roughness of the objects allows them to remain glued to each other in positions not exactly perpendicular to the plane of the conveyor, but inclined by several degrees relative to the perpendicular.
  • the stack that one would like to separate from the objects arranged in a row occupies not a rectangular volume, but a parallelepiped whose front and rear faces on the conveyor are tilted in one direction or the other.
  • the total length of a stack on the conveyor is thus poorly defined. It must be defined by its median length along the axis of the stack.
  • the object of the present invention is a method and said p o-operative part relatively simple for a group of such flat objects, brittle and rough, in horizontal length determined batteries (L), this powered from said objects under form of contiguous rows where they are arranged transversely in planes substantially perpendicular to the axis of the row.
  • the average thickness of said objects is noted below (e).
  • the method consists in first immobilizing the row supplied by the conveyor against a fixed transverse stop of small thickness, ie of the order of 1 / 10th of the height of the row of objects. It is arranged in a plane passing through the axis of the row and parallel to the base plane of the conveyor.
  • the small thickness of the stop and its position in an axial plane parallel to that of the conveyor avoids any asymmetrical force tending to straighten the inclined objects which could cause the said objects to break.
  • the length of the stack formed by the first objects can be measured upstream of the fixed stop along an axial plane. This eliminates, to a large extent, the error due to the tilting of the objects.
  • a second step using a lateral pusher, the objects intended to form the first stack of length (L) are pushed onto a lateral area.
  • L first stack of length
  • a push button small thickness, that is to say a thickness of the same order as that of the stop.
  • the pusher is placed immediately upstream of the stop and moves parallel to the base plane of the conveyor in the same median plane as that already defined by
  • This plane must be between 1/3 and 1/2 of the height of the row of objects:
  • the active part of the pusher seen in plan has an L shape.
  • the large branch of the active part has a length (L - e). It moves while remaining parallel to the axis of the row and constitutes the pusher itself.
  • the small branch hereinafter called “heel” is perpendicular to the large. It extends transversely the front edge of the pusher itself, in the direction opposite to the lateral area, that is to say towards the outside of the row of objects. Its length is at least equal to the width of the objects in the row.
  • the heel and the pusher itself have the same thickness. Thus, when the pusher moves laterally, it remains constantly in the plane defined by the fixed stop.
  • the heel takes the place of the last object pushed back from the fixed stop and maintain the first of the remaining objects in the substantially vertical position. row.
  • the first object remaining in the row is immobilized by the heel which acts as a stop. All the forces are exerted axially on the objects; the risk of breakage is minimal.
  • the conveyor is stopped while the objects are pushed transversely by the pusher.
  • a movable U-shaped stop has its two horizontal branches oriented towards the crackers of the feed row. These two branches frame the fixed stop and the heel as closely as possible in the axial plane perpendicular to the base plane of the conveyor.
  • the branches of this movable stop which were previously erased at the rear of the fixed stop, advance on either side of the fixed stop to the level of the heel.
  • the ends of the two U-shaped arms even extend a little beyond the heel, pushing back the first object remaining on the supply row by a few millimeters.
  • This U-shaped movable stopper thus frees the heel from the contact of the crackers and allows the pusher and its heel to return to their initial position.
  • the transporter is then restarted and the movable stop moves back at a speed at most equal to that of the transporter, allowing objects to advance to the fixed stop, while keeping them on the field.
  • the fixed stop, the pusher and its heel all having a small thickness and being arranged in a median plane with respect to the objects, the variations in length due to the inclination of the objects are largely eliminated.
  • the length of the stack is appreciated substantially along its axis, which greatly reduces the possible error as well as possible jamming against moving parts.
  • the lateral recipe area batteries can be an elevator tray.
  • Two devices for grouping stacked objects can be placed on either side of the tray and form two parallel stacks on the same tray.
  • the tray after loading, goes up or down to a different level where the two formed stacks can be recovery for packaging.
  • FIGS. 1 and 2 we can distinguish rusks of thickness (e) supplied in contiguous rows (1) on a conveyor constituted by a conveyor belt (2) extended by a slide (3). These rusks are most often slightly inclined forward or backward, as shown in Figure 1, and not strictly in exactly vertical position.
  • the arrow F 1 indicates the direction of feeding of the crackers.
  • a lateral plunger (6) of small thickness and length (L - e) is arranged on the side of the row, at the same level as the stop (5). It is integral with a transverse heel (7) extending the front edge of the pusher (6).
  • the pusher (6) and the heel (7) thus form an L-shaped part, as shown in FIG. 2 or 3, capable of moving transversely to the axis of the row (1) along the path defined by F 2 with an amplitude at least equal to the width of the row of rusks.
  • the fixed stop (5), the pusher (6), the heel (7), as well as the edge of the movable guides (4) on the bank opposite the pusher (6) have rounded edges.
  • This rounded shape in vertical section reduces the useful height where these pieces come into contact with the rusks. It makes it possible to consider their respective positions at the diametral plane of the crackers, thus eliminating as much as possible the variations in size of the crackers due to their possible inclination relative to the vertical.
  • a movable stop (9) in U whose two horizontal branches are oriented in the opposite direction from that of the rusks supply. These two branches tightly frame the fixed stop (5) and the heel (7) in FIGS. 1, 3 and 4.
  • This movable stop is capable of advancing against the crackers not yet selected, this up to the level of the heel ( 7), as shown in figure 4.
  • the displacement possible is shown by arrow F 3 in Figure 2.
  • reception area (8) is bordered, upstream and downstream sides by vertical guide walls (10) against which the rusks placed at the ends of the stack are supported. These walls keep the rusks selected in vertical position to form each stack.
  • an elevator tray as a reception area (8) allows the use of two parallel and symmetrical devices for grouping rusks in stacks.
  • the two devices symmetrical with respect to the plate feed a single plate (8) of sufficient size which, during the period when the movable stop (9) moves back, transfers the rusks to a higher or lower level, where packaging can take place. two batteries simultaneously.
  • the device described makes it possible to produce stacks of 15 to 30 crackers according to the length L chosen.
  • the device described can obviously be used for other objects with mechanical characteristics close to those of rusks.
