Abstract

Technology for manufacturing of integral compressed product on a solid stick refers to the process of production of compressed product in food, chemical, pharmaceutical and other industries, so that in the working cycle of tableting and similar machines, a new part of the working cycle of the machine 'insertion' is introduced, during which, by means of a carrying platform (6) with a crank shaped feeding mechanism (7) continual taking of the stick (29) from the charger (20) as well as guiding toward and accurate pushing into the die (14) already filled with the material intended for compression, through the slot (23) closed with a shutter achieved in the form of a leaf spring (9) or a bolt (16) and intended to protect the material intended for compression from scattering when the stick (29) is not inserted, i.e. to hold it firmly attached to the base when already filled into the die (14) and to prevent it from turning laterally due to centrifugal force generated from the rotation of the rotary die table, where the shutter is set on the lock (4) with the lock lifter (5), which lift upward, thus enabling ejection of the final product from the die (14), and thereby the process is completed.

Description

TECHNOLOGY FOR MANUFACTURING OF INTEGRAL COMPRESSED PRODUCT ON A SOLID STICK

TECHNICAL FIELD OF INVENTION

Invention belongs to the field of mechanical, food, chemical and pharmaceutical industry in general. More precisely it refers to a poduction procedure (joining), i.e. way of direct application (by compression) of a granular, powdery, granulated or plastic material (further referred as "material intended for compression "), onto a solid stick. In this way, the stick, made of solid material (wood, metal, plastics, ceramics...) and of different sizes and shapes, using the technological procedure of compression, is directly joined to the material intended for compression whereby a final product, called "integral compressed product on a solid stick", is obtained.

Invention itself refers (is applicable ) to all machines that can be classified as presses specifically adapted for forming shaped products from material in granular or plastic state (IPC - B30B1 1/00) and particularly to the presses using a punch exerting pressure on the material in a moulding space and all variations thereof (IPC - B30B 1 1/02; B30B 1 1/04; B30B l l/06; B30B 11/08; B30B 1 1/10; B30B 1 1/12; B30B 1 1/14).

The mentioned technological procedure of joining, is explained in details through the design and technical embodiment of subunits on the rotary tableting machines. Described subunits completely enable joining of the compressed material, onto one end of a solid stick, by use of compression.

According to the International Patent Classification, this invention belongs to the following categories:

B30B 11/00; B30B 1 1/02; B30B 11/04; B30B 11/06;

B30B 1 1/08; B30B 1 1/10; B30B 11/12; B30B 1 1/14;

B30B 13/00;

B30B 15/02; B30B 15/04; B30B 15/08;

B30B 15/30; B30B 15/32; State-of-Art

Existing machines for production of shaped articles (further referred as "compressed products") from a granular, powdery, granulated or plastic material, exerting pressure on the material inside the moulding space (die) have no technical possibilities for insertion of a stick into the die mould during the process of compressing.

The mentioned technical problem was solved by using special machines for joining (attaching) previously shaped compressed products (with a hole for insertion of the stick) and the stick itself. Thus, two or more machines were necessary to obtain one final product.

The invention in the subject enables design and manufacturing of a device for industrial production of integral compressed products on a solid stick. This production includes continual working cycle of the machine without interruption or stopping the progress of production cycle.

To achieve this, it is necessary to solve the following conceptual and concrete technical problems: concept - principle of inserting the stick into the die (mould) filled with material intended for compression, under an angle;

Theoretical (constructional) and practical (providing a space) introduction of a new part of the working cycle of the machine during the shaping of the final product, which enables inserting the stick;

- Taking the stick from the cartrige to the rotary platform (transport device for conveying the stick to the die) and guiding it towards the die, with insertion into the die;

Construction and accomplishment of an opening on the die through which the stick is inserted into the space filled with compressed material,

- Good quality sealing of the opening on the die box by means of a lock with shutter, so as to prevent, in all working cycles, scattering of the material intended for compression.

- Lifting the lock with shutter in order to enable ejecting the final product (integral compressed product on a solid stick), without any obstacle and damage. In technological sense there is a solution similar to the invention in the subject, which defines the production procedure for sugar lumps on a stick and explained in US patent 3.312.555 under the title "Handle-anchored formed sugar block and method of producing same". This solution belongs to the patent classification which refers to the production of sugar lumps and shaping them by compression in die moulds.

In the technology of industrial production of compressed products, it is not known that a machine which produces integral compressed product joined to one end of a solid stick, is already designed.

Some of existing constructional technical solutions for production of tablets (without adding stiicks) on rotary tableting machines and similar machines are described in US patents 2,989,781-Al ; 3,677,673-Al ; 3,999,922-Al ; 4,108,338-Al ; 4,943,227-Al and many other patents.

These machines, as represented in [Fig. 1], have dies (2) placed along the rim of its rotary die table (1). Their number is defined by requirements and conditions of production, but as a rule, it matches to the number of the working cycles of the machine. In the dies (2) a complete treatment of the material intended for compression up to the obtaining the final product - tablette is carried out throught the three basic steps:

- "dosing" part of the working cycles of the machine which is filling the material

- "compression" part of the working cycles of the machine which is compressing the material,

- "ejection" part of the working cycles of the machine which is ejecting the final product.

Part of the working cycles of the machine "dosing" which is filling the material into the dies (2), represents volume defining of the exact quantity of the material intended for compression which is needed for compression. The process of defining the quantity of the material is defined in [Fig. 2] and is carried out according to the following diagram:

A - die (2) is charged with the material intended for compression,

B - lower punch (3) thereupon lowers to its lowest position,

C - lower punch (3) thereupon lifts, in order to eject the surpluss of the material intended for compression. D - the material intended for compression is levelled by passing below the foot of the dosing unit (19) which is intended for removing the surplus of the material E - as the die is charged properly, preparation for the next working cycle follows.

Part of the working cycles of the machine "compression" which is compressing the material (with or without precompression), represents the phase wherein the material intended for compression receives a solid shape - a tablet shape, using the pressure therefore. Process of compressing is carrried out according to the following diagram in [Fig.

3];

F - the upper punch (11) descends into the die (2),

G - precompression is carried out and therewith air is partially removed from the material intended for compression,

H - part of the working cycle of the machine compression cycle "compression" begins, I - the pressure required therefore is achieved and thereby the process of compressing is completed,

J - upper punch (1 1) is withdrawn from the die (2) and thereupon follows preparation for ejecting the tablet.

,,Ejection" cycle is ejection of a tablet from the die (2), as a preparation to repeat the cycle, i.e. to shape the next tablet. Ejection process is carried out according to the following diagram [Fig. 4];

K - lower punch (3) starts lifting, pushing the tablet from the die,

L - the tablet is ejected from the die (2) onto the plane of the rotary die table (1),

M - the tablet passes the static deflector (8)

N - the tablet is removed from the rotary die table (1),

O - lower punch (3) moves down to its lowest position and is ready for another filling.

In the above described, standard production process for tablets, there is no possibility to insert any solid body in the form of a carrier or a stick into the material intended for compression, due to:

- technological reasons, as design and manufacturing include neither time, nor space for the process of inserting the stick - technical reasons, because there are no:

• Openings on the dies to recceive the sticks

• there is no opportuny for automatic insertion of the stick during the compressing,

• and also no possibility to eject the final product from the die.

Because of the above saids, nothing can be said with regard to the disadvantages of the existing process of production, but about the complete absence of possibility with regard to the compression of tablets on the stick, being solved by herewith described invention.

Disclosure of the Invention

For the purpose of shaping material intended for compression into a compressed product, on top of the stick, first of all, it is necessary to define a new part of the working cycle of the compression machine. It is the forth in total, and the second in order of cycles (immediately after the dosing cycle), technological operating cycle of a press expecially adjusted for the production of articles shaped from material intended for compression. This operating cycle is known as Jnsertion" and it represents inserting the stick (29) throgh a slot (23) on a die (14) wherein further on is carried out the complete process of shaping.

The ,,insertion" part of the working cycle of the machine is carried out, as shown in [Fig. 5a] and [Fig. 5b] of the drawing, and that:

Al - on the carrying platform (6), from the charger (20), a new stick (29) is inserted, Bl - through a groove on a table (30), the stick (29) is pushed towards the die (14), Cl - stick (29) is drawn into the die (14) filled with the material intended for compression, through a slot (23), Dl - at a necessary depth, that is defined by the ending of the crank shaped feeding mechanism (7) El - the lower punch (3) is adjusted so that the stick (29) sets in the middle of the material intended for compression.

To enable compressing of the material intended for compression onto the stick (29), it is first of all necessary to provide efficient, continual inserting of the required number of sticks (29) onto each die (14) in the rotary die table (1), and their positioning at the required depth inside the material intended for compression. The carrying platform (6) with a crank shaped feeding mechanism (7) is an original new solution which complies to all the above mentioned said.

To enable inserting the sticks (29) into the dies (14) filled with material intended for compression, it is necessary to achieve slots (23) thereon. Here it is necessary to provide good sealing during each part of the working cycle of the machine regardless of whether there is a stick (29) in a die or not. Moreover, it is very important that the final compressed product (28), on a stick (29), is ejected through this slot (23) in the part of the working cycle of the machine "ejection". Technical solution here defined as a lock (4) with shutter, is in compliance with all the above mentioned and with novelty and inventive step for patentibility of the product.

Detailed Description of the Invention

As it was pointed out previously, manufacturing of integral compressed products on a solid stick, includes inserting a stick (29) into the die (14) filled with the material intended for compression.

In this invention, the concept which is applied, where the stick (29) is inserted under an angle (most frequently 90°) to the longitudinal axis of the die (14) and the punches (3,11) [fig. 6a]. In other words, in the process of manufacturing the final product, the longitudinal axis of the stick (29) and the longitudinal axis of the die (14), and the axis of the punches (3,11) along which they move, form mutually an angle (most frequently a right angle). The said angle can be slightly smaller than a right angle and depends on the constructional embodiment of the device, but it cannot be close to or equal to the axis of the punches (3,1 1). This way, it is possible to carry out inserting the stick (29) in any phase before the part of the working cycle of the machine "compression", and not when the compressing is already completed, as it was the case in the past, when at least one other device or machine had to be used for inserting the sticks. Thus defined, this is a universal principle that is applicable to all types of machines or presses for production of shaped articles from a material in a granular or plastic state, with a ram exerting pressure in a mould.

Part of the working cycle of the machine "insertion" is characterized by the possibility of adding the sticks (29) through the slots (23) on the dies (14). This part of the working cycle of the machine is carried out as shown in [fig. 5a] and [fig. 5b] comprising following positions: Al, Bl, Cl, Dl and El, and is scheduled immediately after the part of the working cycle of the machine "dosing" (positions A, B, C, D and E) but before the part of the working cycle of the machine "compression" (positions F, G, H, I i J).

So it will, with regard to the order, practically be the second part of the working cycle of the machine. For that part of the working cycle of the machine, it is necessary to designate previously as much dies (14) on the rotary die table (1), as for any other part of the working cycle of the machine individually [fig. 5a]. In our example, this comes up to five dies (14).

The final part of the working cycle of the machine "dosing" (position E) [fig. 2], when the lower punch (3) is being pulled downwards with a previously exactly dosed amount of the material intended for compression, additional adjustments with regard to descending it, at the early stage of the part of the working cycle of the machine "insertion" [position Al, figure 5b] are needed. This step is necessary in order to prevent that, from the already filled die (14) when the the stick (29) is pushed therein, the material intended for compression is not pushed out in the amount equal to the capacity occupied by the stick (29).

The stick (29) is inserted (immersed) under an angle of 90° to the longitudinal axis of the die box (14) or the axis of the punches (3,1 1) [position Bl, fig. 5a] in the previously prepared material intended for compression up to a defined depth [position Dl , fig. 5a, 5b], through a groove (30) of the rotary plate, and a slot (23), in the die box (14). The depth position of inserted stick can vary depending on the requirements, size of the compressed product, the necessary carrying capacity etc., but it may not be greater than the diameter of the compressed product. The next step [position El, fig. 5a, 5b] in this part of the working mode of the machine, is the preparation for the subsequent of the working mode of the machine "compression", and it includes adjusting the lower punch (3) to an exact position so that the mass of the material intended for compression above and under the stick (29) is equal. It is important to perform this adjustment in order to make the compressed product symmetrical, i.e. that the product in the final shape, the stick (29) is located in the center of the lateral side of the compressed product (28) [fig. 12].

Apart from the previously defined order of the parts of the working cycles of the machine, the invention in the subject allows the new part of the working cycles of the machine "insertion" to be carried out in parallel, i.e. simultaneously with the part of the working cycles of the machine "dosing" shown in positions A, B, C, D and E [figures 1 and 2]. In this case, on the rotary die table (1), it is not necessary to design neither space (special die boxes), nor time for carrying out the the part of the working cycles of the machine "insertion", which is the first part of the working cycle of the machine in the order (as is "dosing"). All other actions, of both the punches (3, 1 1) and the sticks (29), are carried out in an identical manner, as above described.

The carrying platform (6) with the crank shaped feeding mechanism (7) enables appropriate taking of the sticks (29) from the charger (20) wherein they are placed in large amounts, and subsequently their inserting into the dies (14) containing the material intended for compression, is enabled. Taking the sticks (29) is possible due to the grooves (21) provided on the rim of the carrying platform (6).

The shape and size of the sticks (29) define the dimensions of the annular ring of the carrying platform (6), the width and depth of the grooves (21), as well. The annular ring of the platform has to be dimesioned so as to be a little shorter than the length of the stick (29) when it is inserted into the die that contains the material intended for compression at the required depth [fig. 6c - detail W]. The width and the depth of the groove (21) are equal in width and thickness with the stick (29), which is used in the process of compressing.

In the area of the rotary die table (1) where in dies is carried out provess of inserting the stick (29) (positions: Al, Bl, Cl, Dl and El), from the lateral side of the rotary die table, and closest to the carrying platform (6) which is firmly fixed to the housing of the compressing machine, the crank shaped feeding mechanism (7) is set. The curve of this mechanism is profiled so as to enable gradual insertion of the stick (29) into the die (14) to a required depth. Its extreme position in the direction of rotation of the rotary die table [figure 6c - detail W], is closest to the carrying platform (6) and defines the maximum depth of inserting the stick (29) into the material intended for compression. In the technical embodiment of this mechanism, it is necessary to anticipate the fine ajusting of its height and depth, as well.

The carrying platform (6) is firmly fixed to the rotary die table (1) and turns continually and synchronously with the rotary die table turning. Arrangement of the grooves (21) on the carrying platform (6) is defined by the arrangement of the dies (14) on the rotary die table (1) and it is achieved so that the longitudinal axis of each groove (21) represents a continuation of the longitudinal axis of each dies (14). This practically means that the number of dies (14) on the rotary die table (1) is identical to the number of grooves (21) on the carrying platform (6).

The turret is the main and executive element of the rotary tabletting machine where the whole process of tabletting, according to the parts of the working cycle of the machine as explained in the state-of-art. The turret consists of three units, which are firmly screwed by bolts, where their concentricity is maintained.

In the case of this invention [figure 6a], the first unit consists of, in the middle positioned, the rotary die table (1) carrying the dies (14). The later has the function of a die mould where the material intended for compression is compacted under the pressure caused by the convergence of the upper punch (1 1 ) and the lower punch (3). The rotary die table (1), around its rim, in a circle of 360°, has symmetrically arranged two-step cylindrical (coaxial) holes, wherein the dies (14) with slots (23) are placed. They differ from, in the state-of-art existing dies, only in a slot (23) providded on the top [fig. 10]. The slot (23) is intended to take a protrusion (24) of the lock (4), which can carry the leaf spring (9) or a bolt (16), and through which the stick (29) is inserted into the die box (14) and it represents a physical extended piece of the groove (30) on the rotary die table (1 ). The internal space of the die box (14), is the die mould which defines the external shape, i.e. the lateral lines of the compressed product and can be of circular, elliptical, square, rhomboidal, irregular shape, etc. The shape of this internal space also determines the shape of the head of the punch (3, 11), the so-called working head or spinning head, which must have an external outline being identical with the shape internal space of the die (14).

In order to achieve the goal of manufacturing compressed products (28) on a solid stick, it is necessary that into the material intended for compression the precise quantity of which is provided into the die (14) a stick (29) is inserted, and then upon the completing the compression process, the final one, compressed product to eject from the die box (14). All this is possible if on the each die (14) is upgraded with a new technical solution being a lock (4) with shutter.

Around each hole in the rotary die table (1) wherein is set a die (14) with a slot (23), there should be made a groove for setting the lock (4). This groove should have a shape of the lock (4) [figure 6c] and [figure 7c] and is deep enough to take its thickness, so that when the lock is down, its top surface is levelled with the top surface of the rotary die table (1). This is important because that surface has to be even and smooth, as the static dosage unit (19) for dosing material intended for compression slides on it, and the static deflector (8) for final compressed products. On the surface of the plate, there should be no protuberances that could make them stumble or get jammed and thus prevent their smooth sliding over the surface.

Opening (lifting) and locking (pulling down) the lock (4), is part of the working cycle of the machine ,,ejection" and is carried out over the lock lifter (5) shown in [figure 6a] and [figure 7a,7b]. The lock lifter (5) has a cylindrical shape and its upper end passes through the opening (guide) in the rotary die table (1). The tip of the lock lifter (5) is shaped like a protruding, which enters the groove made on the lock (4) [figure 7d]. Constructional solution designed as such prevents turning the lock when in open - lifted position, around the longitudinal axis of of the lock lifter (5) in its upper section. Fixing these two elements is carried out with a bolt (12) which is screwed into the thread which is threaded in the axle of the lock lifter (5). On the lower end of the lock lifter (5), in axial direction, there is a groove in the zone where the guide of the lower plate (13) passes through. In this groove, there is a wedge (15) radially fixed with a countersunk bolt (22) through the lifter [figure 7a] and [figure 7b]. As the wedge (15) is inserted into the lock lifter guide (26), turning the lock lifter (5) and the lock (4) itself are prevented. Therewith ensured is that the lock returns to its bearing after every lifting (opening). Connecting the the lock (4) and the lock lifter (5) is achieved by groove connection of these two elements. The lower end of the lock lifter (5) is attached to the crank shaped mechanism that opens and closes the locks just in time. This mechanism exists in the state-of-art and is identical with the mechanism for lifting and lowering the punches, and therefore it is not considered separately.

Inside the protrusion (24) of the the lock (4), the frontal line of which is a part of the internal outline of the die (14), there is a lock shutter leaning on the die box (14) within the zone of the slot (23), which can be embodied in two variations: as a leaf spring (9) or as a bolt (16).

VARIATION 1 : The leaf spring (9), mounted to the lock with a screw (10) [figure 7a] and [figure 8]. This spring has two functions. First, it locks the slot (23) on the die (14), so that the material intended for compression does not leak when there is no stick (29) in it. The second function of the leaf spring (9) is to allow the insertion of the stick (29), from the outside, into the die (14) from the direction of the carrying platform (6) and bring them in a close contact to prevent it from turning laterally due to the centrifugal force produced during the turn of the rotary die table (1 ).

VARIATION 2: Bolt (16), [figure 9a], which turns around the shaft (18), fixed in the lock (4), while upon the bolt (16) acts the spring (17) which enables closing of the bolt during the part of the working cycle of the machine "dosing"". During insertion of the stick (29) into the die, the spring (17) will be loaded and the bolt (16) lifted by a measure corresponding to the thickness of the stick (29) i.e. it slides along the upper edge of the stick (29). This ensures that the slot (23) on the die (14) used for insertion of the stick (29), is closed by the bolt (16) leaning on the stick (29) and ready to withstand the lateral forces produced during the compression of the material in the die box.

The second unit of the turret existing in the state of art, is a lower plate (13) [figure 6a], which carries the lower punches (3) in its guides, which, being concentric with the dies (2), wherein the compression is carried out, ensures that the punches enter the corresponding dies (2) accurately. In order to accomplish this invention, apart from the mentioned punch guides, and in the direction of the center of the lower plate (13), it is necessary to provide lock lifter guides (26) through which the lock lifter (5) pass. In order to prevent the lock lifter (5) from turning, the lock lifter guides (26) are provided with axial grooves (27), wherein the wedges (15), fixed the lock lifter (5), enter.

In this case, the third part of the turret is an upper plate (25) [figure 6a] having the basic task to carry and guide the upper punches (1 1) in its guides. Because of that, the punches accurately enter the corresponding dies (14) on the rotary die table (1). This unit is entirely known in the state of art and is not a subject of this invention.

All technical solutions, changes and subassemblies described above, affect neither the part of the working cycle of the machine "compression", nor the part of the working cycle of the machine "dosing", but these parts of the working cycle of the machine remain unchanged, as it is described in the state of art, with all their variations, forms and subforms. However, the the part of the working cycle of the machine "ejection", due to the stick (29) firmly attached to the compressed product (28) has a slight modification in the diagram, shown in [figure 1 1]: Kl When the lower punch (3) starts lifting, it pushes the compressed product (28) with the stick (29) from the die (14); Ll Along with lifting the lower punch (3), by means of the lock lifter (5) the lock (4) is also lifted thus the compressed product (28) with the stick (29) is ejected into the plane of the rotary die table (1); Ml Coming accross the static deflector (8), situated between plate and bottom face of the lock (4), Nl the compressed product (28) with the stick (29) is removed from the rotary die table

(1), and the lower punch (3) and the lock (4) are lowered; Ol The lock (4) is lowered into its bearing on the rotary die table (1), and the lower punch (3) moves to the lowest position and is ready for filling.

Industrial Applicability of the Invention

The invention, titled "Technology for Manufacturing of Integral Compressed Product on a Solid Stick" enables industrial production of a new integral product consisting of powdery, granular, granulated or plastic material, and which has been compressed on one end of the solid stick. The invention in the subject provides joining two different material structrures (material intended for compression and stick), not using additional technological processes like gluing, welding, tamping and similar, but only applying pressure on the material in the die.

According to the function of the stick (29), the final products - integral compressed products on a solid stick, can be divided into two large groups. The purpose of the compressed product also determines a number of product subgroups:

1. Products where the stick has the function of a mixer or spoon, and the compressed material - product has the role of an additive for consumer liquids: a. Various forms of sweeteners in the shape of a compressed product: i. Natural sweeteners (sugar based): saccharose (white or brown sugar), dextrose, fructose and similar. ii. Artificial sweeteners (like Natreen® or Splenda®): cyclamate, acesulfame, sorbitol, isomalt ... b. Various forms of powder-based beverages in the shape of a compressed product: i. Milk ii. Capuccino iii. Tea iv. Coffee v. Cocoa drinks vi. Juices... vii. Soups c. Various combinations of powder based beverages in the shape of compressed products: i. 2 in one (coffee+sugar,...) ii. 3 in one (capuccino, milk,sugar...) iii. Mix of additives and/or aromas (tea+rum+lemon...) d. Various forms of powder based medical additives (supplements) in the shape of compressed products: i. Vitamins and vitamin drinks ii. Energy drinks iii. Magnesium, Calcium, Selenium ... e. Various forms of medical drugs in the shape of compressed products: i. Effervescent (fizz) tablets ii. Instant powders for mixing with liquids (,,Combined powder") iii. Classic medical drugs for oral use

2. Products where the stick has the basic function of a handle, and the compressed material - product has different purposes (nutritional or non-nutritional): a. Lollipop candy (lollipops), b. Mouth cleaning dragees c. Medical drugs for external use (for application to skin, and similar) d. Medical drugs (pharmaceutical or veterinary) for penetration e. Salts f. Detergents g. Baterries h. Chemical industry i. Metallurgy

When using such final products, there is no need to use other additives or products for faster and easier dissolution, handling, sampling, etc. like spoons, mixers, dosing devices, handles and similar, that is the case with standard products available on the market now. It is possible to package each integral compressed product on a solid stick in a high quality manner, keeping it hygienically sound and ensuring the product durability.

This invention also enables designing and manufacturing all kinds of machines for production of shaped atricles from granular or plastic material, using a punch that exerts pressure on the material in a moulding space, i.e. rotary die plate, with a stick added to it.

Production capacities of existing machines of this type range from several thousand to several hundreds of thousands of final compressed products per hour. This invention produces no effect with regard to the reduction of the production capacity of such machines, but allows identical manufacturing of compressed products on a stick. Thus, this invention completely complies to industrial applicability as a requirement for patentibility, thereby mass production is possible and hence low costs of production.

Moreover, by applying the invention in subject, these machines will be able to perform compression of the mentioned materials directly onto the stick, or without it, depending on actual requirements. In other words, by application of the subject of herewith described invention, the said machines can also produce standard compressed products (without additional handles), while the performance and quality of manufacturing of the final products are retained.
