Description

i - "Method and device for constituting a plurality of stackings

  placed next to each other "

  The invention relates to a method and a

  positive to constitute a plurality of stackings placed next to each other flat pastries, placed

  standing, preferably rusks, at the exit of a banana

  multi-row cooling system arranged at the

following the baking oven.

  There is already known a method for assembling groups following each other of flat objects, such as biscuits or similar products.

  in which these products are extracted from feed hoppers

  located along the conveyor, being pushed transversely to the direction of transport

  in plans of different levels The objects are

  at the exit of the hoppers on suitably arranged slides, where they are first pushed one over the other in the zone of the slides separated from each other to constitute stackings, then

  by continuing their movement in the direction of trans-

  port, they are assembled at the end of the slides in

  Stacks that can be packaged, (DE-PS 10 45 892).

  This method has the disadvantage that for

  stacked upright, flat objects stacked

  on each other, should be rotated 900

  so that the necessary expenditure for this purpose is

2.-

  In addition, a device for

  storing packable stacks which consists of an endless transport member equipped with drive means and feeding hoppers placed one behind the other in the transport direction and associated with this member. biscuits placed in the feed hoppers reach, via

  of a slide on the transport member, means for

  In this way, the biscuits are deposited on each other on the transport member to form stacks. At the end of the transport member, a rake is arranged. extractor which captures the stacks thus formed and transfers them to a pusher From there,

  the stackings to be packaged are transferred to a machine of

  This device is also usable only for the constitution of stackings of biscuits (DE-PS 10 45 892)

  laid flat These two known devices also present

  the disadvantage that they can not be connected

  automatically to a baking oven.

  We also know a method to tidy up

  flat objects that move next to each other

  These objects arrive in several rows parallel to one another and from this distribution they are

  gathered together so that they can place themselves

  above the others in several layers (DB-AS 10 42 484).

  The constitution of a stack according to this method, has the disadvantage that a lot of space is necessary for this storage and that, because of its reduced productivity, the process is not used for machines with high output Finally we know processes for constituting

  standing pilings of flat pastries which

  are in a supine position An automatic feeding device

  3.- tionation of this type is characterized in that the rows are fed on a supply chain of the packaging machine and are likely to be introduced by

  a pusher in the buckets of the chain (DD-PS 40 531).

  In the case of another known device of this type, the

  p Atisseries are brought together by means of

  these and directed at an angle of 900 to a plane of

  by means of bands and guide plates as well as by means of a differentiated dosing and braking device. These pastries are then introduced into continuous successions by means of a vacuum lifting device.

  empty in the buckets of the chain or in other magazines

portions (DD-PS 40 996).

  These two known devices notably present

  the disadvantage that stacking when separating

  the vertical column, are subject to contra-

  These high mechanical stresses by friction are

  particularly unfavorable when treating rusks.

  To avoid these mechanical stresses during the process

  separation, we also know a device in the-

  which rusks are introduced by a band of food

  slightly rising in a feed hopper

  At the end of the feed hopper, a gripper is placed into which the rusks are inserted. After the clamp has been pivoted over a horizontal bucket conveyor,

  the gripper opens and the crackers are

  The following rusks held in the stacker hopper by a separating drawer, then slide to the end of the hopper and are introduced into the gripper returned in place in the gap, (DD-PS 48 941 ) With this device, we can not separate

  small stackings because, because of the existing tolerances

  in the thickness of the rusks, in the case of

  larger pounding, not all crackers can 4.-

tion.

  The object of the invention is to increase the produc-

  such stacking devices.

  The problem of the invention is to automatically transfer, by spares, pastries arriving from the cooling band on a means of transport

  This problem is solved in accordance with

  to the invention, in that the crackers that arrive

  deposited in several rows, are stacked together

  slippery downwards while standing,

  and moving from row to row on a cross track

  with respect to the direction of arrival A constitu-

  Stacking in this way has the advantage of

  ge that stacking can be automatically constituted without

  mechanically grab the pastries Apart from

  the result, no operational effort

  additional is necessary for this purpose.

  According to another characteristic of the invention

  After stacking the stacks according to the desired size, the fully assembled stacks are pushed onto a neighboring track. It is thus possible to form smaller stacks in the case where the rows coming from the cooling strip are larger than the This solution also makes it possible to use the process for large installations because the rows

  from the cooling band, can always

  days be received without difficulty by changing the dimension

  is characterized in that the cooling strip

  has at its end a receptacle in the form of

  sinking down obliquely and extending the whole width of this band, below which a 5.-

  are the subject of the following description.

  The crackers that come from the cooking oven

  its, not shown, on the cooling band 1 by being deposited in twelve rows, slide after leaving this cooling band 1, obliquely to

  down in the slide receptacle 4 While the ban-

  1 is moved continuously, the two-way transverse conveyor 2 is driven step-by-step With each advancement of a step, this conveyor moves with its separation webs 2 c of the width

  in a row The Z rusks are straightened in

  4, so that they arrive on the bottom plate 6 in the upright position, as shown in Figure 3, by sliding against the transverse pusher 5 in the starting position In this way, all twelve the crackers that arrive next to each other, first arrives on the bottom plate 6 The individual pusher disposed in the middle is then also in a starting position, as shown in Figure 1 By moving the transverse pusher 5,

  Z crackers are pushed on the track 2a of the transpor-

  cross-cutter 2 The following rusks gathering

  in the meantime in slide 4, rest in this

  position on the upper part 5b of the transfor-

  Versal 5 Before the back push-back

  sal 5, the retaining barrier 7 comes into action in that the separation drawers 7a, 7b apply against the rear face of the last biscotte Z lying on the track 2a of the transverse conveyor 2 Then, the pusher Transverse 5 is returned to its starting position In this way, the rusks are collected in stackings progressing row by row in a way on the transverse conveyor After the assembly of two times six rusks Z on the corresponding row, the first

  track 2a of the transverse transporter 2 is filled in

  9.- Placement, the complete stacking row gathered in front of the individual pusher 8 is pushed by the movement of this individual pusher 8 on the second adjacent lane 2b of the transverse conveyor 2 In this location also, before the return of the pusher back 8, the retaining barrier 9 comes into action After the return of the

  push button 8 in its starting position, the transmission

  transverse carrier 2 is moved one step

  pitting assembled on the first channel 2 a is then trans-

  carried out of the zone of the cooling band 1,

  o This stack is protected from a fall outside the transport

  2 The push stack on the second track 2b is transported row by row on

  this way, the retaining bar 10 pocketing a sliding

  back of the Z biscuits on the first track 2a, When the stackings were completely assembled on

  the two paths 2a, 2b of the transverse conveyor 2,

  two stackings placed one next to the other of six crackers in the upright position are transferred onto the delivery band 3 connecting to the conveyor. The manner thus described for constituting stacks of rusks is very advantageous because being able to measured

  to obtain high productions without the effort of

  lation, there is a treatment that spares this product whose

tugging is delicate.
