DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a device for firstly orientating vials in general and syringe vials in particular, and then loading them into their sales packages, in particular into thermoformed containers, comprising a seat for each vial, and which are then themselves boxed.
BACKGROUND ART
With particular but not exclusive reference to syringe vials it is known that one of the problems not yet satisfactorily solved is that of loading syringe vials into thermoformed tray containers with industrially required speed, with precision and without causing breakage or damage, these containers when closed and boxed representing the method by which the medicament contained in the syringe vials is sold. Their intrinsic fragility facilitates damage to the vials and to syringe vials in particular, this being difficult to reconcile with the required industrial speed, which itself detracts from adequate precision.
In this respect to load the syringe vials they must firstly be orientated from their vertical position to a horizontal position, and when in this position they must be fed into an underlying recessed container in such a manner that each syringe vial is exactly received by a separate cavity in the container, such cavities being only slightly larger than the syringe vial to be held, for reasons of compactness and adequate retention.
DISCLOSURE OF INVENTION
The traditional methods employed for this purpose are unsatisfactory for one reason or another, the main object of the present invention therefore being to provide a device which is able to totally satisfy the requirements of speed, precision and vial intactness during the said operations. This and further objects which will be more apparent from the detailed description given hereinafter are attained by a device characterised essentially by comprising: a feed section, an endless conveyor with orientatable cells, each for removably receiving at least one vial fed to it by the feed section, and means for modifying the orientation of the cell and hence of the vial during the movement of the conveyor from the feed section to a discharge section which comprises means for simultaneously releasing a predetermined number of vials from the relative cells, with their consequent fall into an underlying container.
In this text the term "vial" also and in particular includes syringe vials (as already implicitly stated).
BRIEF DESCRIPTION OF DRAWINGS
A preferred embodiment of the invention is illustrated on the accompanying drawing in which: FIG. 1 is a schematic plan view of the device of the invention;
FIG. 2 is a perspective view of an orientatable cell, shown in the particular orientation which enables it to receive a vial;
FIG. 3 is a perspective view of the orientatable cell, shown in the particular orientation which enable it to discharge the vial; and
FIG. 4 is a partial perspective view of a detail of a differently shaped orientatable cell.
BEST MODE OF CARRYING OUT THE INVENTION
In the figure the reference numeral 1 indicates overall a feed section which feeds the vials A with vertical orientation along two parallel lines 2, 3 to an endless conveyor indicated overall by 5, and specifically into orientatable cells 6 with which the conveyor in question is formed. During the movement of the conveyor the cells change their orientation so as to move the vials A from the vertical position in which they are received in the cells, to a horizontal position.
Within that rectilinear portion of the conveyor 5 along which the cells 6 are horizontally orientated, means 9 are operated to simultaneously release a determines number of horizontal vials from the relative cells so that they arrive by gravity into an underlying container 7 divided into cavities 8, each designed to hold one vial. In detail, the feed section 1 comprises two parallel feed lines 2, 3. Each of these lines is bounded by active confronting portions 11, 12 of a pair of endless belts or bands 13, 14 situated at such a distance apart as not to exert any conveying action on the vials A w
