Description
Technical Field
The present invention relates to a blowing device for a transport line transporting containers such as bottles and cans or products such as tiles.
Background
Along the transport line for containers or products (commonly known as parcels), air jets aimed at a given target allow to perform various treatments, such as cleaning, drying, cooling, separation.
Along the parcel transport line, the blower usually generates an air flow which is conveyed up a duct to a blower which blows a jet of air in a given direction.
The blower may be a fan or a compressor, for example. Known blowers are for example nozzles or blowing devices configured to blow and direct air jets so as to generate air jets directed in a given direction.
However, the known blower has some disadvantages. For example, nozzles disadvantageously mean high acoustic emissions and high power consumption to generate a suitable air flow rate.
Blowing devices for the transport line generate air jets that extend longitudinally into the direction of advance of the packages. In this way, according to known solutions, the same air jet simultaneously strikes a plurality of parcels (containers or products) advancing along an advancement line.
The known blowing devices have the drawback of not being able to direct the air jets in an ideal manner, which becomes particularly pronounced when the parcels (containers or products) to be treated have a three-dimensional shape, as occurs on bottles or cans.
In other words, the known blowing devices are not efficient in the handling of three-dimensional parcels. Therefore, in order to obtain a fast treatment, it is necessary to apply a complex and expensive layout, which requires a plurality of blowing devices to obtain a respective plurality of air knives at different locations.
Furthermore, the known blowing devices are of large size, which means high manufacturing costs of the apparatus and difficulties in its installation on existing transport lines.
These problems are accentuated during the drying operations performed on packages having an asymmetrical shape, such as bottles or cans, which are usually preceded by a labeling operation. In fact, the axially asymmetric shape does not allow the water to be removed by the action of a simple transverse air flow, since it is simply pushed mechanically to the opposite side of the packet, without actually being removed.
SUMMERY OF THE UTILITY MODEL
The object of the present invention is to provide a blowing device for a transport line which does not have the above-mentioned drawbacks.
According to the utility model, blowing means are provided for a parcel transport line having a sliding plane on which, in use, parcels advance in a first direction. The blowing device comprises a hollow body having an inlet portion for the air flow and an outlet portion for the laminar air jet. The inlet portion is configured to obtain, in use, an air flow generated by the compressor; the outlet portion is configured to blow a laminar air jet out of the blowing device. The blowing device comprises an intermediate portion located on an intermediate plane inclined to the sliding plane and configured so that the laminar air jet has a central axis inclined with respect to the sliding plane at an angle between 5 ° and 85 °.

Detailed Description
In fig. 1, the numeral 1 indicates as a whole a parcel transport line. The term parcel c denotes any type of product to be treated, which is generally advanced on a sliding plane pi 1 according to known methods not shown herein (for example, by means of conveyor belts, rollers, belts, chain conveyors, etc.). In particular, the term package c denotes a three-dimensional product, for example a container such as a bottle (fig. 1 to 4) or a can (fig. 5 to 7).
In a known manner, the parcels c, when lying on a sliding plane pi 1, are made to advance in an advancement direction d1 along an intermediate advancement surface pi 2 perpendicular to the sliding plane pi 1, the sliding plane pi 1 being substantially horizontal, i.e. parallel to the plane on which the transport line 1 lies. The intermediate advancing surface pi 2 is a vertical plane.
In a known manner, the transport line 1 comprises a device for generating an air flow
A blowing device 3 and a duct 4 connecting the compressor 2 to the blowing device 3.
The blowing device 3 comprises a hollow body 5, which hollow body 5 receives an air flow through an inlet section s1
And blows an air jet through the outlet portion s2
The air jet
Essentially diffusing in a central plane pi 3, the central plane pi 3 being perpendicular to the intermediate advancement surface pi 2 or inclined in countercurrent to the intermediate advancement surface pi 2. The expression air jet denotes a free air stream directed in such a way that it forms an air barrier, commonly referred to as an air knife. In particular, an air jet is generated
So as to diffuse over the central plane pi 3.
Fig. 1 and 2 show a preferred embodiment of the blowing means 3. According to fig. 1 and 2, the hollow body 5 of the blowing device 3 comprises in sequence an inlet vent 6 and a blowing duct 7.
The inlet vents 6 face outward from the hollow body 5 through the inlet portion s1 and are configured to receive an air flow generated by the compressor 2
The blowing duct 7 faces outwards through the outlet portion S2 and is configured to direct a jet of air
A blowout blower 3.
According to fig. 1 and 2, the hollow body 5 has an intermediate portion s3, which intermediate portion s3 establishes communication between the inlet vent 6 and the outlet duct 7.
The inlet vent 6 is a substantially axially symmetric tubular body having a longitudinal axis X1.
The middle portion s3 is an opening formed in the side wall of the inlet vent 6.
The profile of the intermediate portion s3 lies on an intermediate plane pi 4, which intermediate plane pi 4 is oriented with respect to the longitudinal axis X1 so as to be inclined, in use, to the sliding plane pi 1 along an ideal line l1 parallel to the advancement direction d 1.
Advantageously, the median plane pi 4 is oriented so as to be inclined, in use, at an angle α with respect to the sliding plane pi 1.
The outlet duct 7 is a converging nozzle with a substantially rectangular passage section for blowing an air jet parallel to the central plane pi 3 from an outlet section s2
The outlet conduit 7 in turn has a central axis Y1. The outlet duct has a passage section s4 (fig. 2), the area of the passage section s4 being variable and decreasing from the intermediate section s3 to the outlet section s 2. In particular, the channel portion s4 of the outlet duct 7 has a decreasing thickness (thickness meaning the extension of the channel portion s4 along an axis parallel to the axis X1 of the inlet vent 6) and an increasing width (width meaning the extension of the channel portion s4 along an axis perpendicular to the axis Y1 and the axis X1) from the intermediate portion s3 to the outlet portion s 2. The rectangular shape of the outlet portion s2 produces a laminar air jet
The laminar air jet
Parallel to the central plane pi 3. The central plane pi 3 is a plane of symmetry of the outlet duct 7 and the central axis Y1 lies substantially on said central plane pi 3. The outlet duct 7 is configured in such a way that, in use, the central axis Y1 is inclined at an angle β in the range 5 ° to 85 ° relative to the sliding plane pi 1.
The passage section s4 is configured to obtain an air jet with a predetermined pressure and velocity
The air jets are schematically shown in fig. 2
Advantageously, according to the detailed view of fig. 2, the profile 8 in the region of the outlet portion s2 of the outlet duct 7 reproduces the inverse of the shape of the respective portion to be processed of the parcel c. In the example of fig. 2, the parcels c to be treated are bottles and the profile 8 is essentially the direct exposure of the bottles c to the air jet during treatment
The reverse face of the portion of (a).
Advantageously, in this way, when the parcels c pass through the air jets
The distance w between each portion of the parcel c and the corresponding portion of the outline 8 is constant at any point.
By doing so, an exposure to air jets of the package c is obtained
The surface of (2) is uniformly treated.
Furthermore, advantageously, the central plane pi 3 is perpendicular to the longitudinal axis X1 of the inlet vent 6. In particular, the inlet vent 6 has a bottom wall 9, the bottom wall 9 longitudinally closing the inlet vent 6. Thus, the entire air flow
Is fed into the outlet duct 7 through the intermediate portion s3, so as to substantially complete the air flow
Offset by 90 deg. with respect to the inlet direction.
This results in a small size of the blowing device 3.
Fig. 3 shows a variant of the blowing device according to the application. All the features described above with respect to the examples shown in fig. 1 and 2 are included in this variant and are not repeated for the sake of brevity. The blowing device 3 shown in fig. 3 further comprises an adapter 10, which adapter 10 is configured to be coupled to the outlet duct 7 in the area of the outlet portion s 2. The adapter 10 has a coupling portion 11 and a blowing portion 12, the coupling portion 11 being configured to be fixed to the outlet duct 7, the blowing portion 12 being opposite to the coupling portion 11.
The adapter 10 is configured to receive, in use, a jet of air from the outlet portion s2 of the hollow body
Advantageously, the adapter 10 can be adjusted so as to vary the profile of the blowing section 12, so that in use the blowing profile 12 reproduces the counter-rotating surface of the parcel c.
According to the example shown in fig. 3, the adapter 10 comprises a plurality of regulating elements 13 interposed between the coupling portion 11 and the blowing portion 12. Advantageously, the adjustment elements 13 are mutually movable in order to selectively vary the profile of the blowing section 12.
According to the example shown in fig. 3, the adjustment elements are belts that can slide relative to each other along the central axis Y1. According to variants not shown herein, the adjustment elements may be configured in different ways, for example, they may be hinged to each other or may be telescopic elements.
Fig. 4 schematically shows another variant of the blowing device according to the application. According to the variant shown in fig. 4, the central plane pi 3 is coplanar with the longitudinal axis X1 (instead of being perpendicular as shown in fig. 1 to 3). In this case, the profile 8 of the outlet portion s2 is substantially parallel to the advancement direction d 1. In this case, as parcel c advances in direction d1, outline 8 is configured to reproduce the unfolded inverse of the outline of parcel c. In other words, the profile 8 is designed to take into account the mutual position during the movement in the direction d1, in addition to the geometry of the parcel c. In any case, even in the solution schematically illustrated in fig. 4, the profile 8 is designed so that the distance w between the profile 8 and the corresponding portion of the parcel c is constant at any point. It should be noted that fig. 4 does not show the blowing device 3 during use, but schematically shows a three-dimensional blowing device 3, while the parcel c rotates in order to show the correspondence between the profile 8 of the blowing device and the profile of the parcel c.
Advantageously, the solution shown in fig. 4 allows the manufacturer to handle a plurality of parcels c simultaneously.
In fig. 5 to 7, reference numeral 103 denotes another embodiment of the blowing device according to the present application. In the case shown in fig. 5, as followsDescribed in more detail, the blowing means 103 comprise a plurality of outlet ducts 7 similar to those discussed above, each outlet duct 7 blowing a respective laminar air jet having a central axis Y
The central axis Y and the sliding plane pi 1 generate an angle beta ranging from 5 deg. to 85 deg..
In the example shown in fig. 5 to 7, the package c is a tank and the profile 8 of each outlet duct 7 is substantially straight. However, without this loss of generality, the same type of blowing device 103 can also be used with packets c having different profiles, for example bottles; in this case, the profile 8 of each outlet duct 7 may be different, for example it may have a profile 8 of similar shape to that shown in figures 1 to 3.
In particular, according to the example shown herein, the blowing means 103 comprise a plurality of outlet ducts 7 connected to the inlet vents 6.
In the example shown here, there are two outlet ducts 7 opposite each other, which are identified as a right outlet duct 7I and a left outlet duct 7 II.
Each outlet duct 7I and 7II is configured to respectively inject a respective jet
I and
II are blown onto the respective sides of the packages c advancing on the sliding plane pi 1.
The blowing device 103 comprises a nozzle 14, the nozzle 14 being configured to blow a jet of air vertically above the parcel c
Advantageously, the nozzle 14 is configured to also generate a laminar air jet
The laminar air jet
Parallel to a central plane pi 3III with a central axis X2, the central axis X2 forms an angle gamma with the sliding plane pi 1.
The blowing device 103 has the advantage of being particularly compact and is able to handle the entire periphery of the parcels c in a uniform and complete manner. Preferably, the blowing means 103 are configured to increase the air flow counter-currently with respect to the advancing direction of the parcels c. In this way, in use, the package c is first passed through a jet of air from the top
III sliding, followed by transverse air jets
I and
II, sliding. This results in the best processing efficiency.
According to a variant not shown herein, the order of the components of the blowing device 3 may be different, i.e. with different distribution along the advancement direction d 1. For example, according to a variant not shown herein, the nozzle 14 can be inserted between the right outlet duct 7I and the left outlet duct 7II along the direction d 1.
In use, a plurality of parcels c are advanced in rows along the transport line 1 in an advancement direction d 1. In the area of the blowing station, each parcel c is subjected to an air jet produced by blowing means 3
Advantageously, the air jets when the parcels c pass the blowing means 3 or 103
While it is exposed throughout the treated surfaceAnd (4) homogenizing. In other words, the air jet
Is constant over the entire treated surface of the parcel c. This allows the manufacturer to achieve the same processing capacity, e.g., the same fluid removal capacity, across the entire treated surface, thereby avoiding deposits/non-uniform areas.
Air jet to which the package c is subjected
Is a result of both the shape of the respective outlet duct 7 and the fact that the contour of the outlet duct 7 has a constant distance w from the envelope c. In other words, the shaped profile 8 of the outlet duct 7 allows the air flow to be uniform over the entire surface of the treated parcels c, thus also making the result of the treatment uniform.
Furthermore, advantageously, the fact that the air jet is laminar and has a central axis Y1 forming an angle β in the range 5 ° to 85 ° with the sliding plane pi 1 allows the manufacturer to obtain a corresponding air jet for the sliding plane pi 1
This simplifies the outflow of the liquid, for example in the case of a drying station, and thus considerably simplifies the set-up of the respective treatment stations along the transport line 1.
Furthermore, the blowing devices 3 and 103 shown in fig. 1 to 3 and 5 to 7 are particularly compact and easy to install, even on already existing transport lines 1. This means a significant saving in space and efficiency.
For the above reasons, the utility model allows the manufacturer to improve the efficiency of the blowing device on the transport line, reduce the occupied space and facilitate the installation operations.
