Description

-1-

  The present invention relates to a device

  the introduction of thin objects, presenting a

  poor quality, brought to the device since its inception

  vertical position in a package or-

  green, by use of a holding plate supporting the objects in this position, which recedes in the packaging as the increasing number of objects introduced into the packaging under the pressure thereof. There are many thin objects whose stability is mediocre; this is the case, for example,

  glass ampoules used in chemistry and pharmaceuticals

  co. The device is therefore explained below

  about the packaging of such bulbs in bot-

  but is not limited to this.

  The problem in the case of such objects which must be packed in large numbers is that they must be transported in the packaging so that they finally fill it

  completely, tightly against each other

  very. During this filling or introduction, a

  objects must not be overturned, otherwise the operation

  fill is disturbed or even made impossible. It should also be mentioned that each package is large enough to receive a very large number of such objects. It has therefore already been attempted to prevent the objects from being overturned by means of narrow channel guides, similar to

  example to bottle filling machines.

  In the case of blister packs in open boots (these are closed only after completion of filling), it is usual to support

  bulbs brought in large quantities to the packaging

  by means of a retaining plate, which is often

  put into action a certain pressure, but back -2- inside the packaging under the pressure of

  many bulbs brought permanently into the

  packing for. The successive bulbs push those in front of them against this plate, and when the latter has retreated to the rear wall of the packaging, it is extracted vertically and the packaging,

  usually an open box, can then be fer-

  both on its filling opening and on its

  from the top. The retaining plate serves as a kind of support for the first bulbs

  which in turn support the following bulbs.

  The only drawback is that the plate of

  restraint retreats exactly transversally to its

  due, therefore parallel to the longitudinal axis of the bot-

  you. The bulbs are not in fact brought uniformly

  the entire width of the filling opening thereon, as would be desirable. As a result

  irregular distribution of the ampoules

  ganes, and especially as a result of the rejection of

  defective or inappropriate before reaching the device, and also as a result of other factors,

  it can happen that significantly more bulbs accumulate

  mulent on one side of the fill opening only on

  the other side. The irregular packing then has to

  sequence that a pressure is established on the side quoted in

  first place between the bulbs introduced into the

  after which several bulbs may tip over to the other side because only a few light bulbs or even

  none are present. This process occurs no-

  at the beginning of the introduction. Such disturbances

  must be absolutely avoided.

  The device according to the invention of the type

  in the preamble avoids such disturbances.

  It is characterized by the fact that the retaining plate

  can rotate around its vertical axis and, when

-3-

  purpose of the introduction, cooperates with

  trices, which are arranged spaced from each other

  on said input side to form a certain number of

  number of compartments which are intended to prevent a reversal of objects. An exemplary embodiment of the device according to the invention is schematically represented on

  the appended drawings, in which:

  Figure 1 is a longitudinal section of the device and the package along the line I-I of Figure 2;

  Figure 2 is a sectional view of

  the line II-II of Figure 1; Figure 3 is a view identical to the

  Figure 2, but only partially, in order to explain

  cation of the operating mode of the device; Figure 4 is a view from the front, in the direction of arrow A in Figure 1;

  Figure 5 is a view of the doubly gripping

corn.

  In Figure 1, the device is represented

  felt on the left half; the right half shows the feeding organs, which will be described later, which

  are shown completely only in this Figure.

  On a base 1, at the front end or filling 2 thereof, is disposed a frame 3, the gantry form is better visible in Figure 4. This frame 3 carries at its opening several small plates 4 , which extend in the direction of filling and form several small inlet channels 5, through which the objects 6, here the

  bulbs, are introduced. These channels 5 are sensitive

  wider than the diameter of the bulbs. The

  However, the size of the bulbs must be adapted so that they can not take an oblique position which is too large as soon as possible.

  the entrance channel, which would lead to a reversal.

  Each inlet channel 5 carries on its lower side a flap 7 and on its upper side a flap 8. The two flaps are angularly folded and pivot each around an axis 9 disposed at the point of flexion 7a, 8a. The upper shutters 8 are here, because of the shape of the bulbs, slightly longer than the shutters

  lower 7, as clearly shown in Figure 1.

  The axes 9 of the upper shutters 8 are arranged in a

  known manner and therefore not represented in de-

  -tail on the lower edge of a door-shutters 10 (represented

  partially reflected in Figures 2 and 3). This holder

  flaps 10 slides in vertical guides 11 in the frame 3, so that it moves in height and can be fixed in the chosen position by any known fasteners 12 (screws, wing nuts,

  etc.). The upper flaps 8 can thus be adapted

  all the bulbs 6 to be packaged. Behind the guide plates 4, looking in the direction of the filling, is a retaining plate 13. It

  role, as already mentioned, of constituting a

  port for bulbs 6 introduced into the channels

  entrance, so that they do not reverse.

  The novelty is that this retaining plate 13 can pivot about a vertical axis. For this purpose, it is provided with a hinge 14, which is exactly

  in the middle of the retaining plate. The joint

  on an arm 15 which, in a known manner and by

  are not represented, can move on a guideline

  ge, so that it can move in the direction in which the retaining plate 13 moves back, so in the direction

  filling. The guidance may be of some form

  conch; but it must have low friction. In the most favorable way, it consists of a socket -5-

  16 and a fixed rod 17, which penetrates

  towards the ball socket 16 and on which moves

  the latter. In this way, a jamming by

  the torque, which is established as a result of the pressure on the retaining plate 13 and the length

of the arm 15, is avoided.

  The arm 15 is on the other hand under the action of a force acting in the direction of the arrow B in Figure 1. It can be here a force of

  spring, but it is advantageous because of the constant

  this necessary the value of the force on the path of movement, whether it is the pulling force of a

  weight to which the arm 15 is connected or also the sleeve

  the ball joint. Hydraulic force action on the arm

15 would also be imaginable.

  The arm 15 is further movable in height.

  in a manner not shown, so that the retaining plate 13 at the end of the race, so on

  the posterior wall of an open boot 18,

  once again introduced into the opening of

  wise. The boot 18 itself is secured against a

  lateral placement by appropriate means, for example

  two vertical guide plates 19.

The device operates as follows:

  On a slide that does not belong to the disc

  positive, which is inclined according to Figure 1, are

  light bulbs 6. The slide (this could also

  be a conveyor belt), serves several

  simultaneously, which are juxtaposed for this purpose.

  A double gripper 21 then grasps two bulbs, the

  raises from the slide 20 and brings them by a movement

  rotational movement about the own axis as well as by a pivoting movement in front of the input side 2 or the input channels 5, after which it introduces the bulbs between the upper and lower flaps 7,8 6- in each channels. In order to be able to describe this movement, the double gripper (which, as already mentioned, does not constitute the object of the invention)

  is mounted on a cardan joint 22 and pre-

  Figure 5 shows two different jaws 23, which can pivot about an axis of rotation 24 on a clamp body 25. Springs 26 which exert pressure on the jaws cause the seizure of two bulbs; a pusher 27 pushes the ends of the jaws 23 against the action of the springs 26 and in this way ensures the capture of the bulbs. The

  -maneuvering elements are also known

  As can be seen in Figures 1 and 2, the bulbs 6 are thus introduced between the flaps 7,8 deviating. The shutters are then brought back into their

  position and hold the ampoules

  them so that these are extracted from the double gripper 21 retreating now against the action

  26. This maintenance also pockets a

  pouring back of the bulbs 6 now

  -gées. Other bulbs supplied by the clamp 21 abut against the bulbs already present and they abut on their side against the retaining plate 13, which is

  in the case of the still empty device

  4 and thus closes the input channels 5,

  but then backs away from the action of the trac-

  weight in the open box 18. The guiding plates 4 ensure a perfect introduction

  bulbs 6 through the inlet channels 5. The

  13 can be placed obliquely according to the filling in ampoules, as is visible on the

  Figures 2 and 3; if as at the beginning of the process of introduction

  only an inlet channel 5 contains many bulbs (Figure 3), then the retaining plate 13 is

  place obliquely, until finally one

  bulbs be moved under the action of pressure

  others in the adjacent entrance channel, possibly

  even in the channel above. The guide plates 4 limiting each channel and the retaining plate 13 thus form, as can be seen in particular in FIG. 3, during the initial phase of introduction, distinct narrow compartments 28, which effectively prevent reversal. said bulbs, even when it is alone in a compartment 28. It can at most take an oblique position, but is corrected, as soon as the clamp 21 begins to fill the channel. If the retaining plate 13 moves further back during the filling operation, the compartments 28 are bounded on each side by ampoules already

  adjacent to the retaining plate 13 (Figure 2).

  Boot 18 is full when the plate

  13 has been pushed back to the posterior wall.

  of it and is then extracted, again

  moved forwards and introduced with caution

  be the bulbs still there to be placed. The extraction

  This could possibly be done automatically by means of a suitable lifting device, actuated by a limit switch, whereas the introduction to the front end is carried out only manually, because otherwise there is a risk of broken bulbs

  by pressure exists. The full boot can then be re-

  drawn; its front side or filling is closed

  and the lid on. This can be done on a machine

  China packing found as a result of the device

  or manually. In the device itself a new

  the open boot is immediately introduced.

  The advantage of the device shown lies mainly in the fact that the filling or the introduction is carried out automatically. In some hitherto known devices, the retaining plate had to be guided by hand. In the case of the device shown, however, the filling operation regulates itself, without any bulb overturning. he

  It is thus possible for an operator to maneuver simul-

  many of these devices.
