Definitions

  • This invention relates to a machine for the production of groups of roll products, in particular, but without limiting the scope of the invention, rolls of toilet paper or kitchen paper.
  • machines of this kind for producing groups of roll products consist of a plurality stations, located in line along the machine itself, where the products are manipulated and divided up to form first the groups of products and then the final packages.
  • the stations basically comprise:
  • the production line may comprise a series of stations for conveying and positioning a plurality of these groups (also referred to as batch - which may include one or more wrapped groups of products) for the end of line stations where the batches can be bagged and palletized, ready for storage or transportation.
  • a series of stations for conveying and positioning a plurality of these groups (also referred to as batch - which may include one or more wrapped groups of products) for the end of line stations where the batches can be bagged and palletized, ready for storage or transportation.
  • the structures that prepare the products for the end of line stations normally comprise the following, in current machines: a system for conveying and, if necessary, diverting the products (with belts and related comb pushers); downstream of this system, there is a product straightening unit that turns each group of products by 90° and to form batches of product groups that are advanced by other comb pushers towards an end bagging machine (usually in a direction perpendicular to the direction in which the batches are fed to the straightening unit) or towards units for picking up and palletizing the groups of products.
  • the straightening unit which may comprise the following (see Figures 1 and 2 illustrating two such units as known in prior art: a pair of parallel endless chains C trained around pairs of power-driven toothed wheels R; the chains C are associated with a plurality of paddles P, protruding radially from the chains C, for picking up, straightening through 90° (from a "lying down” to an upright position) and moving the incoming groups of products G from the conveyor system.
  • Each paddle P is substantially L-shaped to be able to stably accommodate one side L1 and the base L2 of the incoming group G and to turn the latter by ninety degrees.
  • the side of the paddle P that accommodates the base L2 is linked to a pair of guides S associated with the pair of chains C.
  • the number and size of the paddles P mounted on the chains C varies in accordance with the size and configuration of the product groups G made by the machine.
  • roll products come in several different diameter sizes and at least two different pack styles (single or double layer) which means that many sets of paddles P of different widths are required to handle all pack configurations (for current pack configurations, five different sets are used, distinguished by the different colours of the guides).
  • the pack configurations vary in height according to the pack style, that is to say, the height may be that of a single product or the sum of different products placed one after the other within the same group of products.
  • the paddle dimension L1 must vary in length according to the product group G formed by the machine.
  • the product groups G available on the market come in seven different lengths.
  • the products can be variously combined to form at least thirty-five different configurations which the straightening unit must be able to handle.
  • the changeover procedure to be performed on this unit consists of the following steps: stopping the machine; removing all the products of the old configuration; manually disconnecting all the paddle P guides S from the chains C; and positioning another set of paddles P for the new configuration, also performed manually by the operator.
  • the changeover procedure for a straightening unit is a time-consuming, laborious task and, taking into account that changeovers in machines of this kind are quite frequent, that adds up to a considerable amount of down time, which in turn means a significant reduction in machine productivity as a whole.
  • the aim of this invention is to overcome these disadvantages by providing a machine for the production of roll products equipped with a product group straightening unit that is extremely versatile and allows changeover to be performed quickly and without necessitating manual operations on the unit itself.
  • this aim is achieved by a machine for the production of groups of roll products comprising the technical characteristics described in one or more of the claims herein.
  • the machine according to the invention is used to make groups 4 of products, especially but without restricting the scope of the invention, groups of roll products for household or bathroom use.
  • Each of the groups 4 consists of a plurality of products 2, arranged in groups defining a configuration (that varies in accordance with production requirements, as we shall see in more detail below), wrapped in a sheet of film and closed, for example by heat-sealing.
  • the part of the machine which this specification is concerned with and which is labelled 1 in its entirety, comprises at least the following along a feed line A:
  • the first unit 3 may be constructed in different ways, one constructional form being illustrated purely by way of example in Figure 3, and enables the groups 4 to be transferred from the stations where the groups 4 are made to the second unit 5 and, hence, to the end of line stations which are not illustrated or described here since they are of known type and do not fall within the scope of this invention.
  • the first unit 3 may consist of a pair of belts 3a and 3b positioned at an angle to each other to form a system for turning the product groups 4 through 90°.
  • the product groups 4 are moved (and, if necessary, two or more groups are placed side by side) by comb pusher means 3c.
  • the second unit 5 consisting of a unit for "straightening" the product groups 4, is located downstream of the first unit 3.
  • the second unit 5 (see Figures 3 to 7) comprises a motorised endless drive system 6 mounting a plurality of paddles 7 protruding radially from the path line P6 of the drive system 6; each paddle 7 forms, with the next one, a space S for receiving a product group 4 at a position where the paddle 7 is co-planar with the first unit 3, or more specifically, with the upper section 3b (see Figure 4) and is turned through an angle ⁇ of at least ninety degrees in the direction, indicated by the arrow S6, in which the drive system 6 advances.
  • the product groups 4 are positioned side by side on the upper section of the drive system 6, and are then expelled from the respective spaces S by comb pusher means 100 which move them towards the end of line units (not illustrated).
  • the second unit 5 comprises:
  • the paddles 7 of the two groups 7a, 7b are equally spaced to form a working containment space S1 (see Figures 4 and 5), and in the second position, the paddles 7 of the two groups 7a, 7b are positioned close together in pairs to form a second working containment space S2 (see Figures 6 and 7) that is larger than the first containment space S1 defined by the first position.
  • the paddles 7 - there are only two positions that can be adopted by the paddles 7 - in a set number on the drive systems 6a and 6b - to define the transversal dimension of the spaces S.
  • the product groups 4 may have any of a plurality of different configurations according to a first (transversal) dimension LA and included at least between a first, single-layer configuration and a second, double-layer configuration of wrapped products 2 (shown in Figures 5 and 7); each first and second configuration being subdivided into two or more sub-configurations defined by a first, minimum sub-configuration LA1 in which each product 2 has a first diameter D1, and a second, maximum sub-configuration LA2 in which each product 2 has a second diameter D2 that is greater than the first diameter D1.
  • the two positions of the groups 7a and 7b of paddles 7 make it possible to accommodate all the above mentioned configurations and sub-configurations.
  • each paddle 7 of both groups 7a, 7b forms a first working containment space S1, defined as the distance between two consecutive paddles 7, designed to permit the passage and containment of the first configuration, including the respective sub-configurations between the first and the second, minimum and maximum sub-configuration LA1 and LA2 (again, see Figures 4 and 5).
  • each paddle 7 of the group 7b (fixed) forms a second working containment space S2, defined as the distance between the working containment paddle 7 and the next or preceding paddle 7 placed side by side with the next or preceding working containment paddle 7, designed to permit the passage and containment of the second configuration, including the respective sub-configurations between the first and the second, minimum and maximum sub-configuration LA1 and LA2.
  • the size of the spaces S1 and S2 delimited by the two possible positions of the groups 7a and 7b of paddles 7 must satisfy, for each grouping of single- and double-layer configurations, two essential conditions: the spaces S1 and S2 must be able to accommodate the second maximum sub-configuration LA2 (maximum overall and diameter dimension of the product 2) and the first sub-configuration LA1 (minimum overall and diameter dimension of the product 2) must not be able to turn round on itself (i.e. be positioned sideways or aslant) within the space S1 or S2 as the paddles 7 move around and during subsequent expulsion by the pusher means 100.
  • the second maximum sub-configuration LA2 maximum overall and diameter dimension of the product 2
  • the first sub-configuration LA1 minimum overall and diameter dimension of the product 2
  • first and second drive systems 6a and 6b each comprise (see Figure 8):
  • the adjustment means 8 may comprise a mechanical clutch 12 positioned and acting on the drive system 6a and designed to change between two separate states, in the first of which the clutch 12 simultaneously transmits drive to both the drive systems 6a and 6b, causing the groups 7a, 7b of paddles 7 to move normally along the endless path P6, and in the second of which the clutch 12 does not transmit drive to one of the drive systems, namely, the one labelled 6b, so as to keep the respective group 7b of paddles 7 stationary while the group 7a of paddles 7 connected to the other drive system 6a moves in such a way as to vary its relative distance from the other group 7b of paddles 7 between the two above mentioned relative operating positions (see arrows F7a).
  • the mechanical clutch 12 may be operated manually or automatically by a machine 1 control unit 13, represented schematically as a block in the drawings.
  • each paddle 7 of the first and second groups 7a and 7b may consist of a flat member having the shape of an upturned U where the two legs 14 and 15 are connected to the respective drive system 6a and 6b, and where the connecting section 16 of the U defines at least a part of the space for picking up and containing the product groups 4 and a central opening 16g.
  • the U shape of the paddles 7 described in this specification is a preferred non-limiting embodiment of them and, as shown in Figure 12, the paddles 7 might not have the leg 14 and might be connected by the other leg only to a single drive system 6a or 6b, thus forming a rotated L shape: this would create a unit 5 with a lighter structure (without one of the wheel and chain drive systems) while maintaining the same level of operating efficiency.
  • each paddle 7 illustrated makes it possible to define a further adjustment on the second unit 5.
  • the groups 4 of products 2 may have a plurality of additional configurations defined by a second dimension H (longitudinal dimension of the group 4) defined by the height or the sum of superposed heights of the wrapped roll products 2, and included at least between a third, minimum sub-configuration LA3 in which each product 2 has a first height H1 and a fourth, maximum sub-configuration LA4 in which each product 2 has a second height H2 that is greater than the first height H1 (see Figures 9 and 10).
  • the second unit 5 is also equipped with means 17 for adjusting the supporting depth H7 in the working pickup space of the paddles 7 according to the type of configuration and acting at least along an arc-shaped section of the paddle 7 drive path P6 between the above mentioned product group 4 pickup area, where each paddle 7 lies in the same plane as the first unit 3, and the position of the paddle 7 when it has been turned through the above mentioned right angle ⁇ (again see Figures 4 to 7 and Figures 9 and 10).
  • the means 17 for adjusting the supporting depth H7 may comprise, in a first embodiment:
  • the straight surface 19 since the straight surface 19 is positioned at a fixed distance, it must be positioned at a distance H3 from the paddle 7 wall 16 that is smaller than the height H1 of the third, minimum sub-configuration LA3 so as to always allow contact of the wall 16 with any configuration after turning and then lowering the product group 4 along the wall 16 of the paddle 7 until contact with the surface 19.
  • the means 17 for adjusting the supporting depth H7 of each paddle 7 may be positioned and active both along the arc-shaped section and along a straight operating section of the path P6, that is to say, along the active sections, so that the supporting depth H7 of each paddle 7 remains constant between the area where the product groups 4 are received and the area where the product groups 4 are expelled.
  • the means 17 for adjusting the supporting depth H7 may comprise:
  • actuating means 20 may be divided into:
  • the surfaces 18 and 19 themselves are connected to each other by a third, flexible transition surface 21, with tubular cross section, which forms a telescoping sliding connection between the respective ends of the two surfaces 18 and 19, joined to the third surface 21 itself and permitting the double adjustment of the first and second surfaces 18 and 19 by causing the two surfaces 18 and 19 to slide relative to the third, flexible tubular surface 21 (see arrows F21).
  • the actuating means 20, 20a, 20b can be activated by the machine 1 control unit 13 so that all the adjustments described above are coordinated.
  • the spacing between the configuration depth H7 adjustment surface 18 and the paddles 7 means that the surface 18 also acts as a means for relieving the stress created by the pressure on the packages already positioned on the paddles 7 (applied by the product groups 4 positioned on the first feed unit 3).
  • control unit 13 can control the actuating means 20, 20a and 20b in such a way as to enable a forward movement of the first, arc-shaped surface 18, past the predetermined height H, depending on the configuration, and then a guided return movement of the surface 18 itself with the advancing product groups 4 so as to produce said relief action during the feeding of the product groups 4 themselves.
  • the straightening unit can be adjusted in two simple steps and without having to operate directly on the paddles or to change the paddles every time changeover is required.
  • the straightening unit therefore, comprises a set number of paddles that can be adjusted, even automatically, in just two steps:
  • the straightening unit therefore fully achieves the aforementioned aims thanks to a simple, optimized structure that enables changeovers to be performed quickly and accurately without altering the basic architecture of the unit but optimizing and simplifying the cross adjustment system on the many possible product group configurations.
