Definitions

  • the invention to which this application relates is to apparatus which allows an improved handling of articles such as containers and particularly, but not necessarily exclusively, to apparatus which can be used to " debag” a number of articles from a containment package in which the same are supplied to a location for use.
  • the invention also relates to apparatus to be used to move the said articles once released from the said package.
  • the liquid or foodstuff In processing industries, such as food and/or drinks processing, there is a need for the liquid or foodstuff to be dispensed from a holding location, such as a vat, into a range of containers such as bottles or jars, to form a retail item which can then be placed into the retail environment for purchase.
  • the containers can be formed on site and supplied at the location for filling or the containers are formed off site. In either case there is often a need for the containers to be gathered or bagged into a quantity and supplied to the filling location in the packaged condition.
  • the containers are typically retained in this condition by a plastic sheet material surrounding the same and which is provided to enclose the same relatively tightly so as to retain the containers in the required configuration in the package.
  • the sheet material is also provided to allow the containers to be stored hygienically until required to be filled with the storage often being required as a result of the filling of the containers having a quicker throughput than that at which the containers can be manufactured.
  • the containers are required to be debagged or removed from the sheet material package so that the same can be supplied as individual units and moved towards the filling point.
  • the debagging has been carried out by a human operator with a sharp instrument which is used to cut through the sheet material to then allow the operator to remove the sheet material and present the containers into the apparatus for filling.
  • This procedure has several problems.
  • One problem is that an operator is required to be employed to perform this task and this represents a cost to the employer. It can also mean that the containers may not always be provided in the correct orientation to the filling apparatus if, for example, the containers spill out of a partially opened package.
  • a further problem is that the procedure may not be performed in a similar manner each time and there is a risk that the procedure may take too long to perform and thus represent a bottleneck in the filling procedure.
  • a yet further problem is the safety risk which is inherent in the operator having to use a sharp instrument in a time pressure situation.
  • a further problem is that with the human operator performing the cutting action there is a significant risk of contamination of the containers occurring from the operator, the tools used by the operator and, or the cut sheet material which, in due course, can cause contamination problems with the containers and the product with which they are subsequently filled.
  • Document FR2423403 discloses apparatus for removing sheet material surrounding a plurality of articles but does not discloses the use of a blade with teeth formations.
  • US5419095 discloses an apparatus according to the preamble of claim 1 and describes the use of a hot wire to cur through packaging sheet material and
  • DE 1922327 U discloses the use of a blade with a plurality of tooth formations and a base to cut a length of sheet material from a roll of the sheet material.
  • the aim of the present invention is therefore to provide apparatus which allows the debagging of bagged items such as containers, in a manner which allows the process to be performed reliably, safely and repeatedly. Furthermore the aim is to provide the apparatus in a manner which allows the debagging to be achieved by the apparatus without an operator's direct involvement being required. A further aim is to allow the containers to be efficiently moved once separated from the packages.
  • the orientation of the package, the items in the package, the longitudinal axis of the blade and the direction of movement of the blade are selected such that the blade passes between adjacent rows of items in the package without damaging the same.
  • the orientation of the package and items is also selected such that when freed from the package the items are standing on their respective bottom faces on the surface of the apparatus.
  • the blade is provided to be used in conjunction with a tensioning means which causes the sheet material of the package, at least adjacent the location of the first line of cut, to be tensioned or taut prior to the puncture by the blade.
  • the tensioning means includes a nib portion which runs along the length of the blade, at least to one side thereof.
  • the front end of the nib precedes the blade teeth in the direction of the travel of the blade such that the nib contacts the sheet material to tighten the same prior to contact by the blade.
  • the blade and nib are independently movable.
  • a nib is provided to each side of the blade.
  • the tensioning means is biased to the advanced position of the blade teeth so as to ensure that the sheet material is brought to a predetermined tension level before the blade contacts and punctures the sheet material, thus ensuring that an effective and efficient cut of the sheet material is achieved.
  • the action of the tensioning means on the sheet material also acts to move apart the items on adjacent rows and between which rows the blade is to move.
  • the surface of the apparatus on which the package is located is provided with a slot or recess which is shaped and located so as to accommodate the tensioning means and/or blade, thus allowing the tensioning means to move the sheet material of the second face to be cut into the slot to tension the same and for the blade to be moved through the sheet material fully, in order to cut the same.
  • the position of the blade can be altered to suit the particular configuration of the package which is to be cut at that time.
  • the apparatus includes sheet material removal means which act on the sheet material once the cuts have been performed on the same.
  • the removal means in one embodiment are provided in the form of at least a first means which acts to draw a first part of the sheet material, typically that which is parallel with the direction of movement of the blade, when cut, in a direction away from the blade, and second means which then act to grip said first part of the sheet material and move the same in a direction away from the base of the apparatus to fully remove the said part of sheet material out of contact with the items.
  • another set of sheet material removal means are provided to act on the second part of the sheet material on the other side of the cut line.
  • said first and second removal means act simultaneously once the first and second cut parts have been formed by the cutting action of the blade to move the respective sheet material parts out and upwardly from the items.
  • the freed items from the package are then provided to be moved towards further apparatus, which, in one embodiment, may be filling apparatus.
  • the items are containers such as bottles which are to be filled with liquid and the items are moved in rows towards a filling point.
  • the movement means used for moving the rows of items are belts thereby avoiding the possibility of oil or debris contamination occurring.
  • the movement of the items is achieved via servo driven motors and typically the belts are located to the side of the items rather than over the items.
  • the items are moved together as a group in a first direction towards movement means, said movement means provided to move a leading row of items in a new direction.
  • said new direction of movement is perpendicular to the said first direction.
  • the movement in the second direction is achieved by the use of paddles, with, in one embodiment, at least a first paddle at the head of the leading row and at least a second paddle at the rear of the leading row.
  • first and second paddles are independently driven with the respective drive means synchronised.
  • a series of the first paddles are located at spaced intervals on drive chains driven by first drive means
  • a series of the second paddles are located at spaced intervals on a second set of drive chains driven by second drive means.
  • the spacing between the paddles is dependent upon the number and size of items in the leading row.
  • the above apparatus can be used without the need for direct operator intervention and can therefore be performed automatically.
  • the first means to remove the packaging includes one or more suction cups to attract the package part thereto and hence move the package part to the side of the said items.
  • the second means typically includes gripping means which grip the said part and move the surface upwardly away from the base on which the items are mounted.
  • the above apparatus can be used without the need for direct operator intervention and can therefore be performed automatically.
  • tensioning means is further advanced to the opposing wall of the package so as to tension the same.
  • the method further involves the steps of applying a suction force onto opposing uncut side of the package to move the respective first and second cut parts in opposite directions away from the items and subsequently applying a gripping force on the first and second cut parts to move the same away from the items in a second direction.
  • the first movement is a sideways movement and the second movement is an upwards movement.
  • the said first and second drive means each comprise at least one motor provided to drive at least one drive chain on which the paddle is located.
  • a series of first paddles are provided at spaced locations and a series of second paddles are provided at spaced locations along their respective drive chains.
  • the position of said paddles is adjustable to suit the length of the row which is to be moved.
  • the first paddle acts to support the position of the first item in the leading row as it moves and the second paddle acts at the rear of the leading row and acts to "strip" the items of the leading row from the remaining items.
  • the items are containers which are moved by the apparatus towards a location for the same to be filled and which therefore requires that the items are moved in a controlled and accurate manner to the filling location.
  • the first movement means includes a movable portion which is moved to the rear of the items to move the same in the first direction such that successive leading rows of items are presented to be moved by the second movement means.
  • first and second drive means are synchronised so as to ensure that the first and second paddles are provided at the required locations and moved at the required speeds.
  • the motors used in the drive means are servo motors.
  • the package 1 includes enclosing walls 3 formed by sheet material, such as plastics sheet material.
  • the sheet material encloses therein a plurality of items which in this case are a plurality of empty plastics containers 6.
  • the containers are held in rows 19 within the package by the sheet material. In order to be able to fill the containers it is necessary to remove the same from the sheet material while at the same time, ideally ensuring that the containers are retained together as a group, thereby improving the speed and efficiency of the ongoing handling of the same once freed from the package.
  • Figure 5 illustrates the required movement of the containers which can be achieved using apparatus in accordance with the invention.
  • the packages 1 are introduced as indicated by arrow 70 to the base or surface 4 at which a cutting operation is performed by the apparatus as will be described. This opens the package and frees the containers which are then moved as indicated by arrow 42 to a point 72 at which the leading row of the containers are moved as indicated by arrow 44 for subsequent filling.
  • the apparatus includes a surface base 4 on which a plurality of items 6, in this case in the form of plastic bottles, are located in a selected configuration.
  • the configuration is maintained by the sheet material surrounding the same and in which the same are delivered to the apparatus.
  • the sheet material needs to be removed and this is achieved automatically by the apparatus as now described.
  • a blade and tensioning means 8 are advanced downwardly from the position shown in Figures 1a-c down onto the top side wall 7 of the package which lies substantially in parallel with the tops of the containers 6.
  • the blade and tensioning means 8 is shown in more detail in Figure 1c and includes tensioning nibs 10 in advance of a blade 12. This means that the nibs 10 contact the sheet material 3 of the top 7 first and renders the same taut prior to contact by the blade. Typically the tensioning nib and blade are independently movable.
  • A. preferred embodiment of the blade is shown in Figures 2a-c .
  • the blade is elongate and linear and bevelled at one side of the cutting edge 14.
  • a series of teeth formations 16 each having a puncture point 18.
  • the provision of the tensioning nib and the teeth formation in conjunction is found to improve the ability to cut through the sheet material significantly.
  • the subsequent further advancement of the blade allows the whole cut to be performed through the sheet material of the side wall 7.
  • the blade and tensioning means movement is continued in a straight downward path and the package is arranged with respect to the blade such that the blade and tensioning means will pass down and between adjacent rows 20,22 of bottles without damaging the same.
  • the blade and tensioning means eventually reach the opposing side wall 9 of the package and the same cutting process is repeated so as to cut through the side wall 9 with the blade passing into a slot in the base surface 4 so as to ensure that the blade passes through the sheet material to cut the side wall 9. This splits the package into first and second parts 26, 28.
  • Each of the sets 30, 32 comprise first means which include suction cups provided to entrain the sheet material of the respective side wall 36 , 38 of the parts 26, 28 sideways in respective directions perpendicular to the direction of movement of the blade.
  • Second means are provided in each set which include grippers 34 which grip the sheet material and move the part upwardly and away from the base 4.
  • the bottom radius of the external bottles in the group of bottles of the package assist in the sliding movement of the sheet material parts of the package away from the bottles and hence the bottles are then freed from the package and can be moved and filled as required.
  • the movement of the freed containers is achieved, by movement means (not shown) in the form of a plate or portion which contacts a number of the containers from the first opened package towards a further handling point.
  • movement means (not shown) in the form of a plate or portion which contacts a number of the containers from the first opened package towards a further handling point.
  • the containers from the second opened package can be moved forward and so on so as to ensure that the containers are being supplied as required.
  • the containers are moved forwards in a first direction such that there is a provided a leading row of a required number of the containers.
  • the leading row of the containers is then moved in a second direction 44, typically transverse or perpendicular to the first direction 42.
  • This movement is achieved by using a paddle arrangement as shown in Figure 4 .
  • This apparatus includes a first drive means assembly 40 and a second drive means assembly 46.
  • the first drive means assembly includes a plurality of first paddles 48 provided on one or more drive chains 50 at spaced intervals therealong.
  • the first paddles are designed to provide support for the container at the front of the leading row as it is moved in direction 44.
  • the paddles are also provided in the retracted position shown until it is detected that one of the paddles is in the correct position for the first container of the leading row, at which point the paddle is moved outwardly.
  • the second drive means assembly includes a plurality of paddles 50 on one or more drive chains 52 at spaced intervals therealong. These paddles are designed to provide a moving force on the rear container in the leading row so as to move the containers in that row in direction 44.
  • the respective drive chains for the respective paddles are driven by independent motors to pass round the rotational axes 56, 58 with the motors being synchronised to ensure that the respective paddles are in the correct position to efficiently and accurately the leading row of containers. Furthermore the movement of the paddles to the correct position for each leading row can be accelerated so as to increase the speed of operation of the apparatus. It should also be appreciated that the apparatus can be designed to be handed in a particular direction to suit operating requirements.
  • the apparatus as herein described therefore provides a means whereby the items can be freed from the enclosing package automatically and without human intervention being required.
  • the specific arrangements of the invention allow the process to be repeatedly done with a high level of confidence.
