Description

The present invention relates to a device for the transfer

  articles or other objects with a view to

  to undergo a number of treatments or opera-

  tions, these operations and / or treatments being referred to in what follows by the generic term "conditioning". All known devices for the transfer of unitary objects comprise a conveyor consisting of endless chains, provided with transverse plates, integral with two parallel chains and having orifices capable of receiving and holding, for example by their edges, the various objects to transfer These systems

  allow the training of successive rows of

  pies passing in front of the workstations located on or under the conveyor plates which, by the principle of transfer, are obliged to iron on or under the conveyor

  for their return to their original position, these plates

  It is also noted that the return part of such conveyors is equal in elements to the active part and has no other object than that of considerably increasing the price of the machine. Moreover, it is impossible to quickly change the format of the conveyor plates as well as their positioning It should also be remembered that the return of said conveyor plates hinders the workstations while limiting the possibilities of access, for example for maintenance or

repair or cleaning.

  An object of the present invention is to overcome the disadvantages set out above of the machines of the art

  prior art in carrying out a transfer device does not

  not so much conveyor chain while being likely to present multiple industrial applications, especially in the field of various packaging, in particular

those of the containers.

  The subject of the present invention is therefore a device

  the transfer of sundry items, such as

  containers, for the purpose of packaging a product or a mixture of products and ancillary operations such as capping, welding, capsule laying, dating and similar and similar operations, the device comprising: a number of support plates mobile devices independent of each other on which said articles are positioned, these plates moving in a horizontal slide system and being moved in translation clocked by first actuator means so as to occupy successively a number of workstations o are performed a number of operations; pivoting means mounted at the end of the slideway and intended to receive the support plates before being rotated 90 downwards or upwards by means of second actuator means cooperating with third actuator means which drive said plates in translation clocked in a system of vertical parallel rails returning them to a receiving station o under which they undergo under the action of said second actuator means a reverse rotation so as to replace them at the

  level of the horizontal slide system.

  The device for transferring sundries according to

  the invention is furthermore remarkable by the following points:

  first and third actuators

  driving the plates in time-shifted translation are

  killed preferably by pushers driven by a biellegalet system; the means acting at the end of the slideway to cause the support plates to rotate 90 are advantageously constituted by a device consisting of two elements movable in rotation and disposed respectively at each end of the chain, these elements, which consist of lengths of slides cooperating respectively, according to

  whether in a horizontal position or in a vertical position

  with horizontal and vertical slide systems

  of the device of the invention, being brought jointly

  from the horizontal position to the vertical position, and vice versa

  by pivoting about a horizontal axis, the respective vertical and horizontal positions of the elements in question being controlled according to the sequence

  operation and / or treatment of the articles to be packaged.

  Means are also provided for, during rotational movements of the end pivoting elements, to prevent any friction between a support plate received in

  one of said elements and the adjacent support plate.

  Other advantages and features of the invention

  will appear on reading the following description

  of a non-limiting embodiment of an article transfer device according to the invention, with reference to the accompanying drawings, in which: FIGS. 1 to 6 show the various stages of a mode of operation of a device for article transfer according to the invention; and Figure 7 is a schematic view of an embodiment of the transfer device according to the invention. In the drawings, it can be seen that the article transfer device according to the present invention is

  consists of a system of horizontal rails 1 constitut

  two slide rails with parallel recesses la and lb mounted on a frame B, this slide system 1 cooperates with a vertical slide system 2 consisting of two profiled elements 2 a and 2 b of the same type as the slides 1a, 1b of the system. of horizontal slides 1, all these profiled elements of slides being parallel to each other.

  others and having the same spacing.

  In these slideway systems, a certain number of support plates 3 are mounted on which the articles to be treated are positioned, for example cylindrical oblong containers 4 which rest by their rim or peripheral flange 4a on the peripheral zones of boring. 3a having a diameter slightly greater than that of the containers 4. It should be noted that the number of support plates is not critical but depends on the number of operations and treatment that the articles must undergo. the lengths of the slides 1, 2 can be increased by means of similar elements provided that the parallelism and orthogonality relations are satisfied, likewise

  that may be satisfied if an indi-

  as the length of the slides must be substantially a multiple of the cumulative lengths of the support plates which therein

are mounted.

  At each end of the slideways 1, 2 are

  two elements 5, 6 are mounted for receiving the support plates 3 in order to make them rotate appropriately in one direction or the other but always so as to come in the extension of the slides 1 and 2 respectively. To do this, each end element 5, 6 consists of elements identical to the profiled elements la, lb; 2 a, 2 b, these elements 6 a, 6 b being joined by

  respective bracing structures 5c; 6 c.

  The end elements 5, 6 are respectively secured to support parts 7 themselves integral

  of a pivoting axis 9 under the action of a connecting rod system

  crank 10, 11 actuated by motor means 12.

  The clockwise translation movement of the support plates 3 in the slideways 1 and 2 and in the end elements of corresponding shapes 5 and 6 with which said slideways cooperate, is achieved by a device consisting of a pusher member 13 driven in translation. by a rod system 14 cooperating with a roller 15 moving in a slot 16 formed in an actuator 17 which is on the one hand secured to a sliding rod 18 extending inside the pivoting hollow shaft 9, and on the other hand to the push rod 13, the roller connecting rod system is driven by a rotary jack 19 The cooperation in movement of the various elements 14, 15, 17, 18 specified above allows a progressive start in translation from a VO speed up to a speed Vl to tend thereafter towards the original speed VO One thus carries out a cadenced translation of the support plates 3 from one station to another To avoid the fr between the support plates bearing in the rotary end elements 5, 6, respectively, there is provided on the push rod 13 a fixed stop 20 intended to limit the travel of the pusher of the translational movement required to pass a support plate 3 from one station to another This stop 20 comes to bear end of stroke against the wall 21 of the housing C through which slides the push rod 13; between the rear face of the abutment 20, with respect to the direction of thrust movement, and a stop 22 integral with the actuator 17 is provided a

  when the stop 20 comes into abutment

  against the wall 21, the movable element consisting of the actuator 17, the rod 18 sliding in the tube 9 biases the spring 23 in compression to allow movement to create a gap d1 between the plate located by example on the pivoting element 5 and the adjacent plate disposed on the slideways 1 or 2, thus avoiding unwanted and harmful friction between the two plates, each distance dl or d 2 for the end zone 6 having been considerably enlarged to illustrative purposes in Figure 7 of the drawing It is clear that for simplicity only one actuator device and its constituent and cooperating elements has been shown in Figure 7, but that the same device exists symmetrically with respect to the axis of the machine so as on the one hand to carry out the clocked transfer of the plates 3 through the slide system 2 and on the other hand to achieve a gap of the two entrances e the plate supported by the element

  pivoting 6 and the adjacent one located in the slideway 2.

  It is obvious that such a system is provided with elements and means of synchronization allowing the scrolling

  cadenced support plates from one station to another.

  These various sequences are more particularly represented in FIGS. 1 to 7 illustrating the various sequences of plate scrolling.

  is obviously given as a mere illustration of the invention

  It is seen in FIG. 1 that a container R 1 has been introduced, at the beginning of a filling sequence, into a plate 3 adjacent to the plate located in the end element. 2, the pusher 13 (see FIG. 7) has been actuated and the container Ri has been translated to the neighboring station while a container R 2 has been loaded into the plate previously located on the pivoting element 5 which is then Without a plate In FIG. 3, the element 5, together with the element 6 which is secured to it by means of the pivoting tube 9, undergoes

  a downward rotation in which the elements of the

  5 and 6 are fitted in the extension of the slide system 2 As shown in FIG. 4, the actuator device shown in FIG. 7 acts on the push rod so as to introduce a support plate.

  in slide 2 and by successive actions to supply

  plate support the pivoting element 5 while preserving

  the intervals d1 and d2 which will allow an inverse rotation of the assembly 5, 6, 7, 8, 9 so that, as shown in FIG. 6, the first station is replenished in plates, the horizontal chain then containing a certain number of containers, three in the figure, the container having undergone all the operations and / or envisaged treatments and which is in the immediate vicinity of the pivoting element 6 being then taken according to the arrow F 3 The cycle can then start again according to the sequences Figures 3, 4 and 5. This is solved by the cooperation of

  rhythmic translational movements and pivotal movements

  tants, the problem of the transfer of various articles in sequence

  clocked from one workstation to another.

  It is clear that the invention is in no way limited to the embodiment shown in the drawings, but encompasses all modifications and variations within the reach of those skilled in the art. On the support plates, for example, it is possible to envisage the receipt of articles on one support plate. Four bores of appropriate shape can be envisaged in a single support plate.

  which one would have four containers to condition.

  Moreover, it is possible to provide simple means for replacing one type of plate with another type of plate depending on the package to be packaged. In addition, it is possible to modify the location of the abutments on the thrust means and subsequently the race of

  push in order to change the dimensions of the plates.
