Definitions

  • the present invention relates to the field of machines for cartoning of products with multirow feeding.
  • Machines with multirow feeding are a known type of cartoning machines.
  • This term of "multirow” feeding refers to the fact that the cartoning machine receives in input the products (placed on a conveyor, belt or other system of translation) arranged side by side in several substantially parallel rows.
  • the number of rows can be any, for example 6 or 12 rows. Due to this arrangement in rows the products are actually fed by groups (batches) having a number of products corresponding to the number of the rows.
  • the machines with multirow feeding are used typically for products having an elongated shape and a small unitary size, which are well suited to this transport configuration.
  • a typical example is represented by stick packs.
  • the stick pack is a package having an elongated shape, made of paper or plastic, formed by a substantially tubular body closed at the two ends, for example by sealing or gluing.
  • the stick pack experienced a rapid diffusion especially in the field of individually packed products.
  • soluble products including coffee, powdered drinks, etc., sugar or sweeteners, dressings such as oil, vinegar, sauces, etc.
  • single-portion packs which are popular in the field of fast food restaurants for reasons of hygiene and practicality; pharmaceutical products in small or medium dosage, especially in soluble powder, and others.
  • the stick pack is appreciated by manufacturers, in that it allows a certain saving in material, and by customers.
  • a technical problem tackled by cartoning machines with multirow feeding consists in managing the product grouping, i.e. the number of products that the machine has to load in each of the cartons.
  • a batch of products arriving at the machine which, as mentioned above, is formed by the same number of product units as the number of rows, can be:
  • the number of rows is normally set by the lines upstream of the cartoning machine (for example the machines which fill and seal respective stick packs and/or the transport system); consequently the cartoning machine is somewhat "rigid" in respect of the format change, being forced to manage multiples or submultiples of the aforesaid number of rows.
  • the basic operations of the cartoning machine can be identified as receiving the products, their grouping and the so-called loading, referring with this term to the arrangement of the products inside the cartoning, and in the prior art of multirow machines the grouping performed by the loading is substantially constrained to the entrance of the machine itself.
  • Another disadvantage of the prior art is that it does not allow a reliable check as to whether the number of products loaded in a carton corresponds effectively to what is required.
  • the product units transported in multirow formation - for example the aforementioned stick pack - are normally lightweight and small in size, and the probability of an error (product shortage, product fall) is relatively high.
  • the known hopper-based machines therefore suffer a relatively high risk of forming a package out of specification.
  • the object of the invention is to overcome the abovementioned disadvantages.
  • the invention sets out to provide a machine for cartoning of products with multirow arrival capable of managing any grouping, not necessarily multiple or submultiple of the number of rows in input, as well as capable of reliably providing that the grouping corresponds to the specifications.
  • a machine for cartoning of products with multirow feeding comprising: an input section of said products; a first conveyor with single grouping and operating with continuous motion, positioned to receive the products from said input section; a products transfer section from said first conveyor to a second conveyor; said second conveyor having an advance motion which is intermittent and coordinated with the motion of the first conveyor, obtaining a predefined grouping of the products on said second conveyor.
  • the first conveyor and the second conveyor each comprise a plurality of product-carrying pockets or cells or equivalent means.
  • the first conveyor with single grouping comprises cells configured to receive each a single product unit.
  • the cells of the second conveyor can contain any number of products.
  • said first and said second conveyor are linear, i.e. they impose to the products a translation movement along a predefined path.
  • the input section comprises a drop hopper, said first conveyor with single grouping being positioned to receive the products directly from said hopper and convey them towards said transfer section to the second conveyor.
  • the first conveyor is made with a conveyor belt which operates according to a closed circuit; in the transfer section the first conveyor is located above the second conveyor, the advancing directions of the first and second conveyor being on parallel planes. More preferably, in the transfer zone the two conveyors have opposite advancing sense, so obtaining a counter-flow transfer of the products.
  • the second conveyor can serve directly a carton loading section, equipped for example with a top loading robot or with product insertion members, such as for example linear pushers.
  • the second conveyor is represented by a servo train conveyor.
  • Said conveyor which is known in the art, comprises essentially a plurality of servo trains with independent control and motor drive, so that a train can be synchronised with the motion of the first conveyor, while another train can be synchronised at the same time with the loading system (for example robot or other insertion member).
  • the intermittent advance motion of the second conveyor is coordinated with the speed of the first conveyor, in continuous motion, to determine the number of products that are loaded in each of the cells or of the servo trains of the second conveyor.
  • An aspect of the invention provides that the machine is equipped with at least one counting device associated with the product transfer section, and disposed for the single count of the product units which are released from the first to the second conveyor.
  • Said counting device can be used to make available a signal enabling the intermittent advance movement of said second conveyor.
  • the invention allows the control system of the machine to advance the second conveyor only upon a check that the number of product units in a cell (or train) corresponds to the specification. It should be noted that said count is made possible by the single grouping of the first conveyor.
  • the invention allows substantially to remove the link between the multirow input and the load grouping.
  • the grouping imposed by the multirow input is split by loading the products one by one on the first conveyor; at the passage from the first to the second conveyor the groups of products are newly formed, yet without any constraint of compatibility (multiple or submultiple) with the input, the grouping being determined solely by the coordination between the first and the second conveyor.
  • the first conveyor operates as an element of interface between the input section of the machine, forced to the multirow feeding, and the loading section.
  • a machine according to the invention is virtually capable of obtaining any grouping in the cartons and is capable of easily modifying the grouping without affecting the input.
  • the single count also allows the machine to automatically correct a product shortage.
  • the control can maintain a cell or train of the second conveyor in a loading position until the consent of the counting system, so that possible "gaps" on the first conveyor do not generate an error in the loading, for example a missing product in a package.
  • a preferred application of the invention consists of a machine for secondary cartoning of products in stick packs.
  • Another aspect of the invention consists of a method for loading products fed with a multirow formation into cartons, comprising at least the following steps: loading of the products on a first conveyor, with single grouping; transfer of the products from said first conveyor to a second conveyor; said first conveyor having a continuous advance motion and said second conveyor having advance motion which is intermittent and coordinated with the motion of the first conveyor, obtaining a defined grouping of the products on said second conveyor.
  • a cartoning machine receives products in stick packs arranged in multirow configuration.
  • the products arrive via a multitrack chute 1 in a hopper 2 and are loaded one by one in product-carrying cells of a first conveyor 3 with continuous motion.
  • Said conveyor 3 operates in a closed circuit between a product receiving zone 3a and a product delivery zone 3b, and is constituted substantially by a conveyor belt actuated by a motor 4.
  • the conveyor 3 preferably has a path as illustrated, with a rising tilted section passing from the loading zone 3a to the delivery zone 3b. In the zone 3a the products are released directly by the drop hopper 2 into cells of the conveyor 3.
  • the loading into the conveyor 3 is exemplified in Fig. 2 .
  • the stick packs are fed to tracks defined between walls 5 of the loading chute 1, arriving at the hopper 2 in a multirow formation, contained in compartments 6.
  • the example refers to an input of twelve products at a time, i.e. twelve rows.
  • the opening of said hopper 2 causes the products to drop from the compartments 6 into a corresponding number of cells 7 of the conveyor 3 below, at the zone 3a.
  • Each cell 7 carries a single product P.
  • the cells 7 are defined by metal or plastic pockets 8 attached to a conveyor belt.
  • the interface between the first conveyor 3 and the second conveyor, denoted generally by 9, is shown in Fig. 3 .
  • the second conveyor 9 in the example is a servo train conveyor with intermittent movement. It comprises a plurality of servo trains, each being formed by a plurality of pockets 10 which define product receiving cells 13. Each of said cells 13 can contain a product P or possibly a plurality of products P adjacent or stacked one above the other.
  • the conveyor 9 comprises at least two conveyor belts with independent control and motor drive and, consequently, at least two servo trains which are driven in an independent manner.
  • the pockets 10 are attached to the respective conveyor belt with blocks 11 which allow quick fitting and change.
  • the second conveyor 9 feeds a loading section of the products inside the cartons, which can be for example cardboard packets.
  • This section can be made with a known technique and according to the relevant needs and therefore is not described in detail.
  • the second conveyor 9 can feed a loading system comprising a top loading robot or a series of inserting members which transfer the products directly into the cartons,
  • the second conveyor 9, realized with the abovementioned servo-trains technique can be driven in such a way that at least one servo train is charged to receive products from the continuous conveyor 3, while another servo train feeds said loading system.
  • the content of one or more of said cells 13, according to the configuration of the machine corresponds to the carton grouping, i.e. to the number of products per each carton.
  • a closing assembly can be provided downstream the loading section, still according to a per se known technique.
  • Fig. 3 shows an embodiment wherein a return portion of the first conveyor 3 is positioned directly above a portion of the second conveyor 9, so that the products P pass from the cells 7 of the first conveyor to the cells 13 of the second conveyor below by a free falling.
  • Guides 14 are provided around the pulley 15 of the conveyor 3 which extend to an end 14A, beyond which the product P falls into a cell 13A below.
  • the cell 13A is then located in the actual zone of transfer of the products from one conveyor to the other.
  • the sense of the advance of the conveyors 3 and 9 is denoted by A and B, respectively. It can be noted in the figure that the sense A of advance of the first conveyor 3 is opposite to sense B of advance of the conveyor 9, in the transfer section 3b.
  • the described arrangement with a section of the first conveyor above the second conveyor, and counter-flow movement on parallel planes, is advantageous in terms of the compact size, in particular reducing the overall length dimension, and of the constructional simplicity.
  • the machine comprises an optical sensor (not shown) which allows the single count (one by one) of the products passing from the continuous conveyor 3 to the cell 13A of the conveyor 9.
  • the sensor can be positioned at the end 14A of the guide 14 to detect the products which one after the other fall into the cell 13A.
  • the conveyor 9 moves one step forward, bringing the next cell into the loading position.
  • the control system thanks to the counting sensor, can receive the information of the number of products which have actually passed into the cell 13A and, therefore, can enable the forward movement of the conveyor 9 only when said number corresponds to the functioning specification of the machine.
  • the machine can thus manage any "gaps" (product shortage) on the conveyor 3. If for example one of the cells 7 is empty, the system can delay the forward movement of the second conveyor 9 until the correct number of products is present in the cell 13A.
  • the method according to the invention is exemplified in the diagram of Fig. 4. It comprises substantially a step 100 of products arrival in a multirow formation; a step 101 of single transport of the products; a step 102 of grouping; a step 103 of loading in cartons.
  • the operation of single count of the product units, indicated by the block 104, is carried out between the steps 101 of transport and 102 of grouping.
  • the step 100 of arrival takes place at the hopper 1; the step 101 of single transport is operated by the first conveyor 3; the grouping step 102 takes place during the passage of the products into the second conveyor 9, thanks to the coordination between the latter and the first conveyor 3.
