- the peristaltic pump comprises a contact body which can move by sliding relative to the main body, the tube can be checked and substituted, if necessary, in an extremely simple and rapid fashion. It is sufficient to move the contact body along the main body to move the inner wall away from the rotor, creating the access compartment and freeing the tube.
- This operation is simple to perform, since it only involves lifting the covering door to cause the contact body to slide.
- Another advantage indicated above relates to the angling of the intake and delivery couplings. Since said couplings are parallel with each other, the constrictions produced by the rollers cover an arc of a circle substantially equivalent to 180°. As already indicated, this increases peristaltic pump efficiency both at low and high speeds, and means that the pump is much more compact than prior art pumps.
- Another advantage of the peristaltic pump in accordance with the present invention relates to the contact surface which is partly formed by the inner wall of the contact body and partly formed by the curved surface of the base of the main body.

Abstract
Description
- The present invention relates to a peristaltic pump. In particular, the present invention is applied in the food industry. More in particular, the present invention is applied in machines for producing and dispensing crushed-ice drinks, sorbets, ice creams, soft ice creams, cream, yoghurt and the like and in machines for producing and preserving mixtures for ice cream, creams, sauces, soups and mixtures in general and the like.
- Peristaltic pumps of the known type comprise a containment body housing a flexible tube in which a fluid flows, the fluid being pumped from an intake section to a delivery section.
- In detail, the containment body is made of two half-parts which are connected to each other.
- Prior art pumps comprise a rotor which is rotatably connected to a first half-part of the containment body, the outside of the rotor supporting a plurality of idle rollers positioned with their axis of rotation perpendicular to a direction of tube extension.
- The rollers are in contact with the tube and, in conjunction with a contact wall opposite the rotor relative to the tube, they create respective tube constrictions.
- As the rotor drives the rotation of the rollers, the constrictions are moved from intake to delivery to convey a portion of the fluid contained in the tube between two constrictions which come one after the other.
- The tube comprises an intake coupling and a delivery coupling and is made of flexible plastic material such as polymeric or silicone material.
- The diameter of the tube, in conjunction with the speed of rotation of the rotor, determines the pump capacity.
- The contact wall is made in a second half-part of the containment body.
- In prior art peristaltic pumps the two half-parts of the containment body are rigidly connected. For example, in prior art peristaltic pumps the two half-parts are connected by screws.
- Disadvantageously, when the tube must be substituted if there is a fault, the two half-parts must be moved away from each other in order to move the wall away from the rollers and free the tube so that it can be extracted from the containment body.
- Said operation is very complex and laborious, since it requires pump containment body disassembly.
- Moreover, if the pump capacity has to be changed, substituting the tube with another having a different diameter is not sufficient.
- The width of the contact wall is substantially equal to the width of the tube at the constriction.
- Consequently, it is not possible to insert a flexible tube which has a greater diameter, since said tube at the constrictions would exceed the width of the contact wall.
- On the other hand, if a tube with smaller diameter were inserted, said tube could not be effectively housed and might exit its position with significant consequences in terms of pump operation.
- In this context, the technical purpose of the present invention is to propose a peristaltic valve which is free of the above-mentioned disadvantages.
- In particular, the present invention has for an aim to propose a peristaltic valve which is easy to maintain.
- Another aim of the present invention is to propose a peristaltic valve which can easily be adapted to various capacity requirements.
- Accordingly, the present invention achieves said technical purpose and the aim specified with a peristaltic valve comprising the technical features described in one or more of claims herein.
- Further characteristics and advantages of the present invention are more apparent from the nonlimiting description which follows of a preferred embodiment of a peristaltic pump, illustrated in the accompanying drawings, in which:
-
Figure 1 is a schematic front view, partly in cross-section, of a peristaltic pump in accordance with the present invention in a first configuration; -
Figure 2 is a schematic front view, partly in cross-section, of the peristaltic pump ofFigure 1 in a second configuration; -
Figure 3 is a schematic side view of the peristaltic pump ofFigure 1 in the first configuration; -
Figure 4 is a schematic side view of the peristaltic pump ofFigure 2 in the second configuration; and -
Figure 5 is a schematic side view, partly in cross-section, of the peristaltic pump ofFigure 1 in the second configuration. - With reference to the accompanying drawings, the
numeral 1 denotes as a whole a peristaltic pump in accordance with the present invention. - The
peristaltic pump 1 comprises amain body 2 and acontact body 3 which is slidably connected to themain body 2. - A
tube 4 made of flexible material is positioned between themain body 2 and thecontact body 3. - As explained below, the
tube 4 allows the transit of a fluid to be pumped from anintake section 5 to adelivery section 6. - The
tube 4 comprises anintake coupling 7 located at theintake section 5 and adelivery coupling 8 located at thedelivery section 6. - The
peristaltic pump 1 also comprises arotor 9 which is rotatably connected to themain body 2 and supports a plurality orrollers 10. Therotor 9 rotates about its own axis of rotation "A" which is perpendicular to a direction in which thetube 4 lies (Figures 1 and 2 ). - In the embodiment described, the
rotor 9 comprises acentral shaft 11 and two paralleltriangular brackets 12 at whose vertices threerollers 10 are supported. - Each
roller 10 is separated from the others by an equal angle of 120° relative to therotor 9 and lies with its own axis of rotation "B" substantially perpendicular to the direction in which thetube 4 lies and, therefore, substantially parallel with the axis of rotation "A" of therotor 9. - The
rotor 9, whose rotation is driven by drive means which are not illustrated, gives the rollers 10 a circular trajectory, which may have a clockwise or anti-clockwise direction when observingFigures 1 and 2 . - The
contact body 3 comprises a vaultedinner wall 13. - Said
inner wall 13 has a section, made along a plane perpendicular to the axes of rotation "B" of therollers 10, which substantially has the shape of an arc of a circle in such a way that its concavity is towards therotor 9. - In more detail, the
flexible tube 4 lies between theinner wall 13 of thecontact body 3 and therollers 10 of therotor 9. - The
contact body 3 can move by sliding between a first position and a second position towards/away from therotor 9. - In detail, in the first position the
contact body 3 lies in such a way that theinner wall 13 is at its closest to the rotor 9 (Figures 1 and3 ). In particular, theinner wall 13 is at its closest to therollers 10. - In this first position, the
tube 4 lies compressed between therollers 10 and theinner wall 13 in such a way that therollers 10 press thetube 4 against theinner wall 13 so as to form local constrictions. In said case, theinner wall 13 at least partly forms acontact surface 14 for thetube 4. - In practice, the
rotor 9 drives the rotation of therollers 10 in which the corresponding constrictions move from theintake section 5 to thedelivery section 6. In this way, a portion of fluid contained between two constrictions that come one after the other is conveyed from theintake section 5 to thedelivery section 6. - In contrast, in the second position the
contact body 3 lies in such a way that theinner wall 13 is at its furthest from the rotor 9 (Figures 2 ,4 and 5 ). In particular, theinner wall 13 is at its furthest from therollers 10. - In this second position, the constrictions are freed and a
tube 4access compartment 15 is formed, making tube extraction simple. - The
peristaltic pump 1 also comprises movement means 16 connected to thecontact body 3 for moving it between the first and second positions. - In particular, the movement means 16 comprise a covering
door 17 pivoting at themain body 2 and connected to thecontact body 3. - The covering
door 17 can rotate between a lowered position corresponding to the first position of thecontact body 3 and a raised position corresponding to the second position of thecontact body 3. - In more detail, when the covering
door 17 lies in the lowered position, it covers a hollow space formed between themain body 2 and thecontact body 3 when the latter lies in the first position. - Moreover, in the lowered position, the covering
door 17 has afront surface 17a which, in conjunction with afront surface 2a of themain body 2, forms anuninterrupted front surface 1a of theperistaltic pump 1. - In the raised position, the covering
door 17 lies distanced from themain body 2 and frees theaccess compartment 15 formed when thecontact body 3 is in its second position. - It should also be noticed that rotation of the covering
door 17 from the lowered position to the raised position causes thecontact body 3 to move from the first position to the second position. - The covering
door 17 comprises afront panel 18 and two parallellateral shoulders 19 connected to opposite sides of themain body 2 and of thecontact body 3. - In particular, the covering
door 17 comprisespins 20 inserted incorresponding housing cavities 21 made in themain body 2 allowing rotation relative to the latter (Figures 3 and 4 ). In more detail, thepins 20 are made on thelateral shoulders 19 of the coveringdoor 17. - The covering
door 17 also comprises twoprojections 22 made on theshoulders 19 and eccentric relative to thepins 20. Theprojections 22 are slidably inserted instraight guides 23 made on opposite sides of thecontact body 3. - When the covering
door 17 rotates about itspins 20, theeccentric projections 22 slide along theguides 23, causing thecontact body 3 to move between the first and second positions. - The
contact body 3 comprises twotongues 24 located at its opposite sides and which can be housed incorresponding guide grooves 25 made in themain body 2. - Moreover, the
contact body 3 comprises twocentral tabs 26 which are parallel with each other and housed inrespective recesses 27 made in themain body 2. - The
tongues 24 and thetabs 26 allow thecontact body 3 to slide stably and efficiently relative to themain body 2. - When the
contact body 3 is in the second position and the coveringdoor 17 lies in the raised position, thecavities 21 for receiving thepins 20 and thestraight guides 23 are aligned and communicating with each other. In this configuration, eachpin 20 and eachprojection 22 is aligned with the correspondingguide 23. - In this case, the covering
door 17 can be moved in such a way that thepins 20 can exit the receivingcavities 21 and enter the straight guides 23. In this way, the coveringdoor 17 remains connected to thecontact body 3 but it is disengaged from themain body 2. In other words, thecontact body 3 can be moved away from themain body 2. - The
peristaltic pump 1 also comprises afirst sleeve 28 and asecond sleeve 29 connected to thecontact body 3 and open at the sides for housing respectively theintake coupling 7 and thedelivery coupling 8 of thetube 4 and keeping them in the correct position. - The
intake coupling 7 and thedelivery coupling 8 preferably lie parallel with each other. - Consequently, the
first sleeve 28 and thesecond sleeve 29 also lie parallel with each other. - In this embodiment the
contact surface 14 is semi-cylindrical. Advantageously, this allows the constrictions to be maintained for as long as possible so as to increaseperistaltic pump 1 efficiency above all at high operating speeds. - The
main body 2 comprises a supportingportion 30 and a base 31 which are fixed to each other. For example, the supportingportion 30 is fixed to thebase 31 by screws. - The
rotor 9 is rotatably connected between the base 31 and the supportingportion 30. In other words, thetube 4 is housed between thecontact body 3 and the supportingportion 30 of themain body 2. - The
contact body 3 slides on the base 31 towards and/or away from the supportingportion 30. - In the preferred embodiment, the
base 31 comprises acurved wall 32 at least partly forming the contact surface 14 (Figures 2 and5 ). - More precisely, when the
contact body 3 lies in the first position described, thecurved wall 32 made in thebase 31 is alongside theinner wall 13 of thecontact body 3. In this way, thecurved wall 32 and theinner wall 13 form, in conjunction with each other, asingle contact surface 14. In other words, the constrictions formed by therollers 10 in conjunction with thecontact body 3 also partly extend in thebase 31, lying on thecurved wall 32. - The
curved wall 32 has a predetermined width so that when thecurved wall 32 is drawn near theinner wall 13, the overall length of thecontact surface 14 is substantially equal to the width of thetube 4 at the constrictions. Similarly, therollers 10 have a length substantially equal to the width of thetube 4 at the constrictions. - If the
peristaltic pump 1 capacity has to be changed, thetube 4 must be substituted. In detail, it should be noticed that one of the things on which the capacity of theperistaltic pump 1 depends is the internal diameter of thetube 4. If the capacity must be increased, thetube 4 must be substituted with another tube that has a bigger diameter. Similarly, if the capacity must be reduced, thetube 4 is substituted with a tube having a smaller diameter. - In any case, the width of the
contact surface 14 must be substantially equal to the width of thetube 4 at the constrictions. Consequently, after changing thetube 4 the width of thecontact surface 14 must also be adapted. - Advantageously, in the embodiment described, the width of the
contact surface 14 is adapted simply and rapidly by changing only thebase 31. - A plurality of
bases 31 may be prepared, each having thecurved wall 32 with a predetermined and distinct width, so that, in conjunction with theinner wall 13 of thecontact body 3, the width of thecontact surface 14 is adapted according to the diameter of thetube 4. - As a result, if the
peristaltic pump 1 capacity must be changed, it is sufficient to substitute, as well as thetube 4, only thebase 31 and therotor 9, without working on any other parts of theperistaltic pump 1. - In another embodiment, not illustrated, the
peristaltic pump 1 comprises a spacer which is positioned between the base 31 and the supportingportion 30. - In this case, the
curved wall 32 is made on the spacer. To change the capacity of theperistaltic pump 1 by changing thetube 4, only the spacer needs substituting. - The invention achieves the preset aims and brings important advantages.
- Since the peristaltic pump comprises a contact body which can move by sliding relative to the main body, the tube can be checked and substituted, if necessary, in an extremely simple and rapid fashion. It is sufficient to move the contact body along the main body to move the inner wall away from the rotor, creating the access compartment and freeing the tube.
- This operation is simple to perform, since it only involves lifting the covering door to cause the contact body to slide.
- Another advantage indicated above relates to the angling of the intake and delivery couplings. Since said couplings are parallel with each other, the constrictions produced by the rollers cover an arc of a circle substantially equivalent to 180°. As already indicated, this increases peristaltic pump efficiency both at low and high speeds, and means that the pump is much more compact than prior art pumps.
- Another advantage of the peristaltic pump in accordance with the present invention relates to the contact surface which is partly formed by the inner wall of the contact body and partly formed by the curved surface of the base of the main body.
Claims (17)
