Definitions

  • This invention relates to a process for handling products.
  • the products are preferably rolls or paper or the like, especially rolls of toilet paper and/or household paper or all-purpose paper towels.
  • a process for handling rolls of paper or the like, especially rolls of toilet or household paper is well known, where the roll products are obtained by cutting at least one long roll, or log, transversally into a plurality of individual rolls of suitable length.
  • patent application No. US 2005/0132904 describes a process for embossing a log with different motifs to obtain different batches of individual rolls and sending all the rolls obtained from one log embossed with different motifs to a packaging machine.
  • One disadvantage of processes of this kind is that the products are fed to the packaging machine according to a fixed sequence, where the products of a first batch are placed before the products of a second batch, making it impossible, at least with the packaging machines known up to now, to obtain packs of desired configuration attractive to consumers. In other terms, it greatly limits the possibility of making up packs containing products with different designs that ensure a good presentation.
  • WO 00/05138 discloses a process for handling products according to the preamble of claim 1.
  • Figure 1 illustrates a configuration P of the products contained in a respective pack, which comprises a plurality of products in the form of respective rolls 11a, 11b of different types.
  • the pack P is completed by a suitable plastic wrapping which covers and holds the rolls 11a, 11b together.
  • the wrapping is not illustrated in Figure 1 .
  • the products to which the invention applies are preferably rolls or paper or the like, especially rolls of paper for sanitary use and/or paper for household use or all-purpose paper towels.
  • this preferred pack P comprises two rolls of household paper or all-purpose paper towels 11b and four rolls of toilet paper 11a.
  • the packs might have any other desired configuration, the roll products differing from each other in other ways and being, for example, rolls made of different materials, differently embossed or coloured or printed with different decorative designs.
  • packs of different types from the pack P illustrated here, containing a different number of rolls, rolls arranged in different ways or rolls of different sizes.
  • each individual roll comprises a core 11', normally made of paperboard, on which is wound a paper web 11" consisting of a plurality of superposed plies and comprising regularly spaced tear lines to make predetermined lengths of paper.
  • rolls 11a, 11b have a longitudinal axis "L” and substantially cylindrical lateral surfaces 112' and 114', respectively, and opposite transversal faces 112a,114a and 112b, 114b.
  • the rolls have respective diameters Da, Db, which are the same in this embodiment, and respective lengths La and Lb, the former of the toilet paper roll and the latter of the household paper roll.
  • a first preferred example of an installation for making and packaging products, in particular roll products comprises a log cutting machine, labelled 12 in Figure 3 , which cuts the rolls from respective logs.
  • the machine or cutting section 12 receives the logs 13 (illustrated in Figure 2A ) from a suitable buffer station, which is not illustrated in the accompanying drawings and which in turn receives the logs from a machine further upstream where the logs are made in a customary manner by winding a web of paper or other material round a paperboard core until the desired diameter is reached.
  • the cutting machine makes a plurality of transversal cuts T in each log 13 to form individual products 11a, 11b of suitable length La - and Lb.
  • the products are then transported by suitable conveying means from the cutting machine 12 to packaging means which are in the form of a first and a second packaging machine 18a and 18b.
  • these conveying means comprise upstream conveying means 16, located immediately downstream of the cutting machine 12, and first and second downstream conveying means 16a, 16b which receive the products from the upstream conveying means 16 and transport them to the packaging machines 18a, 18b.
  • the upstream conveying means 16 comprise means 20 for diverting the products towards different destinations and, more specifically, towards the downstream conveying means 16a, 16b.
  • the product diverting means 20 comprise fixed conveying means 22 and mobile conveying means 24.
  • the fixed conveying means 22 of the diverter or distributor 20 receive the rolls cut by the blade 12a which is illustrated schematically in Figure 5 .
  • the rolls are transported by conveying means or belts of the machine 12, at the cutting area, by aerial conveying means (not illustrated) which advance the rolls in a suspended condition, that is to say, holding them from above.
  • Said aerial retaining means keep the rolls in a suspended condition after picking them up from the belts of the log saw upstream and release them onto the fixed conveying means 22 of the conveying means 20.
  • the mobile conveying means 24 have a fixed end 24a at the respective end of the fixed conveying means 22, and a mobile end 24b that can be positioned alternately at the first downstream conveying means 16a and at the second downstream conveying means 16b.
  • the mobile means 24 are vertically mobile.
  • the cutting machine 12 has four parallel feed belts and four retaining suspension belts which feed out four parallel rows of products obtained by the simultaneous cutting of four logs by the circular blade 12a, shown schematically in Figure 5 .
  • the products fed out of the machine 12 travel first on the four fixed belts 22 of the diverter 20 and then on the four mobile diverter belts 24 which convey them alternately to the four belts of the first conveying means 16a or to the four belts 16b of the second conveying means.
  • the products are then fed in four parallel rows to the respective packaging machines 18a, 18b, said machines 18a, 18b receiving the rolls conveyed, respectively, by the first conveying means 16a and by the second conveying means 16b, whose respective first sections in turn extend one above the other at different heights.
  • the products cut from each log 13 comprise at least a first batch 13a of products 11a and a second batch 13b of products 11b, where the products 11a of the first batch 13a differ from the products 11b of the second batch 13b and where the first and second batches 13a, 13b each comprise one or more products 11a, 11b, respectively.
  • the log 13 material used to make the products of the first batch 13a might have a different surface finish from the material used to make the products of the second batch 13b.
  • the material forming the products of the first batch 13a might be embossed differently from the material forming the products of the second batch 13b.
  • the material forming the products of the first batch 13a might have a different decorative design from the material forming the products of the second batch 13b.
  • the material forming the products of the first batch 13a might be coloured differently from the material forming the products of the second batch 13b.
  • the products of the first batch 13a and the products of the second batch 13b differ in length and, more specifically the products of the second batch 13b are twice as long as the products of the first batch 13a, the former being rolls of all-purpose paper towels and the latter being rolls of toilet paper, all the rolls being equal in diameter.
  • the products 11b of the second batch 13b are positioned upstream of the products 11a of the first batch 13a, relative to the direction of log feed and, hence, of product feed.
  • the first product batch 13a is separated from the second product batch 13b.
  • the first product batch 13a cut from a log is separated from the second product batch 13b cut from the log before the two batches leave the cutting machine.
  • the products feeding out of the cutting machine 12 are thus ready to be handled by the conveying means 16 downstream of the machine 12.
  • the first product batch 13a cut from a log and the second product batch 13b cut from the log are separated from each other directly on the conveying means and, more specifically, at the moment the conveying means receive the products from the cutting machine 12.
  • separating a first product batch 13a from a second product batch 13b, both cut from a single log involves spacing the first product batch 13a from the second product batch 13b cut from the log 13.
  • spacing the first batch 13a from the second batch 13b of products is achieved by cutting the log in such a way as to cut off a portion 11c between the first and second product batches 13a, 13b.
  • This intermediate, or scrap, portion 11c is removed and is not conveyed to the packaging units downstream, thereby creating a suitable gap "d1" between the rear face of the last product in the first batch 13a and the front face of the first product in the second batch 13b, as illustrated by way of example in Figure 2B .
  • the intermediate portion 11c may differ in length from the products 11a, 11b of the first batch 13a and of the second batch 13b of products.
  • the intermediate portion 11c may be shorter than the products 11b of the second batch 13a and longer than the products 11a of the first batch 13a.
  • the products of the second batch 13b consist of longer rolls and, more specifically, maxi rolls of all-purpose paper towels, while the rolls of the first batch 13a are shorter, being rolls of toilet paper.
  • the first batch might consist of longer rolls and the second batch, shorter rolls, used for respective purposes.
  • the products 11a of the first batch are advantageously kept together in a group.
  • the products 11b of the second batch are also kept together in a group.
  • the rolls, or products, of the first and second batches 13a, 13b are transported along the conveying line downstream of the cutting machine and, more specifically, in the zone 16 of the conveying means that is immediately downstream of the cutting machine, in such a way as to keep the transversal faces of each roll close to, or in contact with the transversal faces of the adjacent roll, that is to say, with a gap "d0" between the transversal faces of adjacent rolls, so that if a roll, or product, tends to tip over, its transversal face engages the transversal face of the adjacent roll, or product. This prevents the products from tipping over and avoids the down time and economic loss that would be caused by personnel stopping the installation to set the products straight.
  • the gap d0 between the rolls might be necessary to enable sensors, by detecting this gap, to count the rolls as they advance along the feed line.
  • the products obtained from one log 13 are divided into groups or batches 13a, 13b each containing a smaller number of products than the total number obtainable from that log 13, allowing the groups themselves to be handled in suitable fashion.
  • the products 11a of the first batch 13a and the products 11b of the second batch 13b are sent to different destinations and, more specifically, are sent, or diverted, to different conveying means 16, 16b.
  • the gap, or spacing, "d1" between the products of the first batch 13a and those of the second batch 13b feeding out of the cutting machine 12 is suitably varied and, in particular, widened by means of the drive motors of the conveyor belts 22 and 24 of the diverter 20.
  • the gap between the products of the first batch 13a and the products of the second batch 13b might be varied on the conveying means 16 when the latter receive the products from the cutting machine.
  • the conveyor belts might be made to move at a different speed from the speed of the feed belts inside the cutting machine.
  • the gap between the first and second product batches might be created, or widened, solely and exclusively by the conveying means 16 and, more specifically, by the diverting means 20.
  • the gap between the first and second product batches might be created, or widened, solely and exclusively by the conveying means 16 by making the belts 22 and the belts 24 of the diverting means 20 move at different speeds.
  • the products of the upstream batch 13b from one log 13 and the products of the downstream batch 13a from the next log 1-3' are sent to different destinations 16a, 16b, that is to say, to different conveying means 16a, 16b.
  • gap, or spacing, "d2" between the last product of the upstream batch 13b from one log 13 and the first product of the downstream batch 13a from the next log 13' as they feed out of the cutting machine 12 and said gap, or spacing, is varied, in particular, the gap, or spacing, between the last product of the upstream batch 13b from one log 13 and the first product of the downstream batch 13a from the next log 13' by suitably operating on the product conveying means 20.
  • the products 11a, 11b obtained from one log 13 are sent to a single packaging machine 18a according to a particular arrangement suitable for creating a desired pack.
  • means are provided for arranging the products in a plurality of parallel rows, where a plurality of products 11a, 11b forming a respective transversal front "F" comprise products that differ from each other.
  • the product front "F” comprises the products suitable for forming a pack and which, in particular, are obtained from a single log 13.
  • the transversal front row of products 11a, 11b is created by a diverter 20, by first diverting the batches 13a, 13b of products to respective conveying means 16a, 16b, in practice diverting the product batches obtained from a single log 13 to different conveying means 16a, 16a.
  • rows of products from different conveying means 16a, 16b are made to converge until they are parallel with each other at the zone where they are fed to a respective packaging machine, that is to say, rows of products from different conveying means 16a, 16b, which are vertically spaced or aligned are made to converge with each other.
  • the products 11a, 11b that form a transversal front of products to be packed are fed in parallel and simultaneously to respective packaging means 18a.
  • means 19a, 19b are provided for conveying the products to a packaging machine 18a, these being in the form of first and second means for simultaneously feeding the products 11a and 11b to the packaging machine 18a, said first and second means each comprising a respective pair of conveyor belts extending in the same plane at infeed to the machine 18a.
  • the products of the first batch 13a and the products of the second batch 13b from different logs 13 are sent consecutively to a single packaging machine 18a on respective first feed means 19a, 19a and 19b, 19b.

  • the products 11a and 11b can be advantageously distributed to obtain the desired pack P.
  • the product front F is defined by two consecutive transversal rows of rolls on the conveyors 19a, 19a and by single transversal rows of products on the conveyors 19b, 19b.
  • the products 11a on the first conveying means 16a and the products 11b on the second conveying means 16b are sent alternately and consecutively to the first feed means 19a and to the second feed means 19b.
  • means are provided for diverting the products 11a from the first conveying means 16a towards the first and second feed means 19a, 19a of the respective machine.
  • Means are also provided for diverting the products 11b from the second conveying means 16b towards the first and second feed means 19b, 19b of the respective machine.
  • the means for diverting the products towards the first and second feed means 19a, 19b comprise conveying means 21a, 21b extending at different heights, where the conveying means 21a comprise mobile means 21c that may be activated to send the products alternately to the first feed means and to the second feed means when the installation is used to make traditional packs containing rolls of the same type.
  • Means 23a, 23b are also provided for merging the flow of products from the conveyors 21a and 21b towards the first feed means 19a and, respectively, towards the second feed means 19b which cause the four channels of the conveyors 21a, 21b to merge into two respective channels of the conveyors 19a, 19b.
  • means 25 are provided for diverting the product flow from the conveying means 16b towards the means 19 for conveying the products to a second packaging machine 18b, or towards the first packaging machine 18a when the installation is used to feed different products towards the single packaging machine 18a, in this case diverting the flow of products 11b from the second means 16b towards the product feed means 21b downstream instead of towards the means 19 that feed them to the second packaging machine 18b.
  • Figure 6A shows in a schematic view the area 20 for diverting products from the cutting machine upstream implementing the roll handling process.
  • this second example differs from the first in that each log 113 is divided into a first batch 113a of rolls 111a, a second batch 113b of rolls 111b and a third batch 113d of rolls 111d.
  • the rolls 111a of the first batch 113a are, relative to the direction A in which the rolls are conveyed, are situated downstream of the rolls 111b of the second batch 113b and downstream of the rolls 111d of the third batch 113d.
  • the log saw blade cuts the products of the first batch 113a and of the third batch 113d into equal lengths and, in particular, equal to half the length of the rolls of the second batch 113b, which, as illustrated, is situated between the first and third batches 113a, 113d.
  • the products of the second or middle batch 113b are rolls of household paper or all-purpose paper towels, while the rolls in the end batches 113a and 113d are rolls of toilet paper.
  • the pack obtained in this case may be identical to the pack illustrated in Figure 1 .
  • the rolls are made by a respective cutting machine or log saw that forms respective logs 113 which are then cut into individual rolls by the log saw blade in a manner similar to that of the first preferred embodiment.
  • the second example also spaces the rolls of the first batch from those of the second batch and the rolls of the second batch from those of the third batch before they leave the cutting machine.

  • the separation between the roll batches 213a, 213b, 213c may be achieved by providing respective scrap or trimmed portions designed to create between the batches 213a, 213b, 213c a gap which can be widened when the rolls have been received by the conveying means downstream of the log saw and which must be wide enough to enable the mobile portion 24 of the diverter 220 to switch from one position to another.
  • Figure 8 which illustrates the subdivision of the log 213 into batches, does not, however, show said scrap or trimmed portions between the first, second and third batches.
