Description

1. "Device for transfer, with precise guidance by

  the side edges of flat bakery products

they can be preserved. "

  The invention relates to a device for the transfer, with precise guidance by the side edges, of flat bakery products that can be stored, preferably

  rusks, arriving in rows on a cooling strip

  in troughs sloping obliquely and

  side walls parallel to their axis, with a view to

build up stacks.

  There is already known a method for constituting several

  juxtaposed stacks of baked flat bread products

  can be stored, standing, preferably

  crackers, directly following a cooling strip

  several rows arranged after the baking oven.

  In this process, the rusks arriving lying down in several rows and sliding obliquely downwards,

  in the upright position, are assembled in transverse stacks

  towards the feeding direction, row by row while progressing in a slide. The corresponding device

  is constructed so that the cooling band com

  door at its end, a trough reigning over its entire width, descending obliquely, and subdivided by side walls. Beyond the cooling strip, is mounted a cross-shaped wedge-shaped slide, moved back and forth, and attacking at right angles to the inclined chute, with an ascending bottom plate. a corresponding inclination. At the same level

  this bottom plate connects to a trans-

  versal inclined in the same way with ribs separating

  and which is provided at its entry with a retaining lock (DE-OS 32 47 420). This device has the disadvantage that due to the axial drift of the rows of rusks arriving on the cooling strip, the width of the chute

  subdivided should be provided somewhat larger to

  disturbances when entering the chute. This necessary widening of the chute results in a laterally disordered arrival, so that the stack forming at the end of the chute, therefore have misalignment. Another disadvantage is, moreover, that in the case of large axial drifts,

  the rusks strike the front side walls

  and block the arrival of other crackers.

  The invention aims, by constituting stackings

  correctly aligned, to avoid disturbances during the

  packaging and thus increase the productivity of

  manufacturing and packaging lines of this type.

  The problem of the invention consists in axially aligning

  Before stacking, the rusks ar-

  lying down, without any obstacle when entering

  in the chutes. This is achieved in accordance with the

  tion thanks to a device characterized in that it comprises a centering slide disposed upstream of the troughs, and which is subdivided into a number of individual channels

  same as the chutes, the bottoms of these

  dividends descending from one side to the separating ribs of these channels and extending in the form of a helix,

  so that the rusks whose center of gravity is

  above the separation ribs come sliding in

  the individual channels apply to the exit of the slide

  centering laterally against the separating ribs

  3.- tion by being aligned. The various rusks thus align advantageously themselves in the axial direction, so that with a reduced expense, it can constitute

  irreproachable stacks with smooth faces.

  According to another characteristic of the invention, the

  centering slide is provided adjustable transversely.

  This ensures, by transverse adjustment of the feed chute, an introduction without incident into the chutes of the rows of rusks arriving on the cooling band, even in the case of axial drifts

  very large ones exceeding the tolerance width of the

  individual goles. To make it possible to compensate for the axial offset of the individual channels, with respect to the troughs

  coming next when setting the center of gravity

  after the centering slide the walls of the

  coming in the following are first of all

  flexible guidelines that are set at the top of the

  separation and at the bottom, fixed walls. To enable automation of the process of setting the

  centering slide, above the cooling strip

  provision is made for an optical surveillance device

  luent the axial drift of the rows of rusks, in order to

  the centering slide by means of a repositioning motor

  SETTING. The invention will be explained in more detail with reference to an exemplary embodiment shown in the accompanying drawings in which: - Figure 1 is a side view of the device according to the invention, Figure 2 is a street in Direction of the arrow y of Figure 1, - Figure 3 is a section along line AA of Figure 1 - Figure 4 is a section along the line BB of Figure 1, 4.- - Figure 5 is a plan view towards the arrow x of FIG. 1, in the case of a slide

  centering offset from the cooling band

  is lying. FIG. 6 is a view similar to that of FIG. 5, but for a centering slide aligned with

the cooling band.

  The device consists essentially of a

  centering slide 2 descending obliquely and connecting

  to a horizontal cooling strip 1, slide downstream which are arranged, with the same inclination, adjacent troughs 3 of parallel axes. At the end of the troughs 3, there is a stacking device 4 which

  will be described in more detail below.

  The cooling strip 1 consists of a wire strip 1a and drive rollers 1b, of which only the downstream roll is shown in FIG. 1. On the downstream part of this cooling strip 1, is arranged

  a band of application lc to block in position the bis-

  2C Z coats arriving. The centering slide 2 coming after comprises individual channels 2a corresponding to the rows arriving on the cooling strip 1, and which are separated by separation ribs 2b with a slope

  steep. The bottom 2c of these individual channels 2a, is

  in such a way that with respect to the separating ribs

  2b associated with it, it descends obliquely to a side and has a helical shape. Tilt and shape

  2c are used so that the biscuits Z come

  end at the end of the centering slide 2 against the corresponding separation rib 2b in alignment. The centering slide 2 is mounted so that it can be adjusted transversely on an adjusting rod 2d of a setting motor 2e. This adjustment motor 2e is connected, via a piping system, not shown, with an optical monitoring device 2f 5.-

  placed above the cooling strip 1. The

  The following chutes 3 are formed first of all by flexible guide plates 3a, which are fixed at the top to the separation ribs 2b and at the bottom to the fixed walls 3b. The stacking device 4 located at the end of the slide, consists of a stop lever 4a, a

  transverse slide 4b and piling chimneys 4c extend

  in the direction of travel of the trans-

  versal 4b. At the end of stacking chimneys, is

  4d retainer block for Z biscuits.

  Positive stacking 4 is also completed for each government.

  3 by a twisting spring with two arms 4e mounted so as to be pivotable, and whose upstream arm is engaged on the cracker Z arriving, while the other arm enters

  downstream of the biscotte Z in the chute 3.

  The mode of operation of the device thus de-

  crit is as follows: The crackers Z arriving lying in rows of the baking oven, not shown on the cooling strip 1, slide after having abandoned the cooling band 1

  obliquely downwards, first in the

  2. This centering slide 2 is then adjusted transversely continuously by the monitoring device 2f and by means of the adjustment motor 2e by means of the adjustment rod 2d,

  Z biscuits arriving with their center of gravity

  above the separation ribs 2b, slip into the

individual channels 2a.

  It is therefore necessary to distinguish essentially two operating states, as they are represented on

  Figures 5 and 6. Figure 5 shows the position of the slide

  centering position 2 when a drift from the cooling strip

  dissement intervened. This drift of the tape la and the resulting adjustment stroke for the slide of 6.-

  centering 2, can be easily recognized by a

  Reason with the representation of Figure 6 o the cooling band is centered. Due to the inclination of the grooves 2c, on the centering slide 2, the rusks Z then slide laterally until they

  are applied against the separation ribs 2d.

  The centering slide 2 is then adjusted to such an extent that the drifts of the rows in their imprecise deposition on the cooling strip 1, or at shifts of the cooling band 1 itself, are again

  compensated. This transverse adjustment of the center slide

  ge 2 corresponds to a coarse adjustment, while centering

  or a precise alignment of the various Z rusks

  kills himself on the centering slide 2.

  After leaving the centering slide 2, the rusks Z slide while applying laterally against the guide plates 3a, and then against the walls 3b,

  up to the stacking device 4. In the stacking device

  In step 4, the Z rusks are applied against the lever

  4a and are transferred by means of the transom slide.

  versal 4b in stacking chimneys 4c. The holding blockings 4d then prevent a fallout of rusks out stacking chimneys 4c. Due to the pinch spring 4e, sliding following the next cracker Z is prevented, because the downstream arm of the pinch spring 4e

  enters chute 3, while in its other posi-

  terminally it releases this chute again, but then the upstream arm is applied to the previous Z biscuit, so that only one rusk can slide to the lever

stop 4a.

  With this device, aligning the crackers Z, it is advantageous to obtain stacks of rusks with

smooth side surfaces.
