Definitions
- the invention relates to a device and a method for packaging items, in particular confectionery, such as lollipops .
- lollipops in sheets of packaging material, such as plastic film.
- the lollipops are held in stick clamps which are arranged on a rotatable drum.
- a sheet is positioned at the head side of the lollipops, then folded over and around the head and wrapped and heat-sealed on the stick side of the head.
- two rotatable arms provided with heated pressing ends, the arm ends, as well as a stick clamp which rotates the lollipop together with the folded sheet.
- the heating of the arms is effected by means of a supply conductor, which is connected by means of a movable coupling to a power supply which is fixed to the machine.
- a device for packaging items in particular confectionery, such as for example lollipops
- a packaging conveyor such as a rotatably driven drum, having a series of holders rotating along a movement path for holding each item and its associated packaging sheet securely while conveying, a feed station for feeding the items and the packaging sheets to the packaging conveyor and a discharge station for discharging the items packaged on the conveyor
- the packaging conveyor being provided with means for closing the packaging sheet on the respective item and with a series of heat-sealing means co- rotating with the holders for heat-sealing the closed packaging by supplying heat
- each of the heat-sealing means comprising a sheet gripper which is provided with a heating body

- control means are provided with a first memory for storing a desired value for the temperature of the heating bodies, the device furthermore comprising means for measuring the temperature of each heating body, the control means being designed for controlling the heating means for that heating body based on the result of a comparison between the desired value and the last measured value of a heating body.
- control means comprise a control system and a second memory for discrete storage of values which are indicative of the historic state of the control system of a heating element, the control system being designed for controlling the heating means for said heating body based on the values for the historic state of the control system for the relevant heating body, the desired value and the last measured value of the relevant heating body.
- control means comprise a separate control system for each heating body, which allows each heating body to be controlled in an optimum manner .
- control means comprise one control system for discretely and sequentially controlling the various heating bodies.
- the second memory is in this case designed for discrete storage of the values for the historic state of the control system for the various heating bodies, the second memory making the values of the historic state of each individual heating body sequentially available to the control system for sequentially controlling the various heating bodies.
- the measuring means are stationary relative to the movement path of the holders, in particular on the outside of this path.
- the measuring means may be designed for contactless measurement of the temperature of the heating bodies.
- the heating means are designed for contactless heating, from outside, of the heating bodies.
- the heating means may be stationary relative to the movement path of the holders.
- the heating means and the measuring means are placed at regular intervals along the movement path of the holders. This makes it possible to at least reduce a possible interference between the heating by the heating means and the temperature measurement by the measuring means .
- each sheet gripper with heating body can be moved between a non-operating position and an operating position, the heating means being arranged such that heat is supplied to the heating body when the sheet gripper is in the non-operating position.
- the measuring means may in this case be arranged such that they measure the temperature of the heating body when the sheet grippers are in the non-operating position.
- the packaging conveyor may be provided with wrapping means for forming a twisted end section of the packaging sheet while packaging the respective item and the heat-sealing means are arranged such that they heat-seal the twisted section or an adjoining region of the packaging sheet by supplying heat.
- wrapping means and heat-sealing means may be provided for each holder, the wrapping means and heat-sealing means preferably being designed such that they can operate during conveying thereof through the packaging conveyor .
- the sheet grippers may comprise pairs of clamping arms which are arranged on the packaging conveyor so as to be able to rotate about an individual rotation shaft, the path of the rotation shaft being situated at a shortest distance from the heating means which is smaller than the clamping arm length.
- the clamping arms can in this case be moved between an operating or clamping position directed at the rotation shaft and a projecting position or non-operating position directed away from the rotation shaft, the heating means being arranged in a section of the heat-sealing means, in which the clamping arms are in the projecting position, in which they extend preferably radially relative to the rotation shaft.
- only one of the clamping arms is provided with a heating body.
- the clamping arms may be rotatable about their rotation shaft in a direction counter to the direction of rotation of the packaging conveyor.
- the heating means may comprise induction means for heating the heating body by means of induction.
- the induction means may comprise a stationary induction coil which is arranged in the movement path of the sheet gripper.
- the induction coil may be arranged such that the coil shaft is transverse to the movement path of the holders.
- the sheet gripper also forms part of the wrapping means .
- the sheet gripper may be provided with a layer of heat-insulating material which protects the heating body in a direction other than the clamping direction.
- the holders are designed for holding lollipops provided with a stick and a head.
- the sheet gripper may be arranged such that it operates on the side of the lollipop head facing the stick, such as for a bunchwrap machine.
- the device is suitable for double twist-wraps.
- the invention provides a device for packaging items, in particular confectionery, such as for example lollipops, comprising a packaging conveyor having a series of holders for holding each item and its associated packaging sheet securely during conveying, a feed station for feeding the items and the packaging sheets to the packaging conveyor and a discharge station for discharging the items packaged on the conveyor, the packaging conveyor being provided with means for closing the packaging sheet on the respective item and with a series of heat-sealing means co-rotating with the holders for heat-sealing the closed packaging by supplying heat, each of the heat-sealing means comprising a sheet gripper which is provided with a heating body, the device furthermore comprising means for heating each heating body as well as means for measuring the temperature of each heating body and means for controlling the heating means based on the measuring means, the measuring means being designed for contactlessly measuring the temperature of each heating body .
- the temperature can be measured without deformation and/or friction, thus making it possible to increase a fault-free period of operation.
- the invention provides a device for packaging items, in particular confectionery, such as for example lollipops, comprising a packaging conveyor having a series of holders for holding each item and its associated packaging sheet securely during conveying, a feed station for feeding the items and the packaging sheets to the packaging conveyor and a discharge station for discharging the items packaged on the conveyor, the packaging conveyor being provided with means for closing the packaging sheet on the respective item and with a series of heat-sealing means co-rotating with the holders for heat-sealing the closed packaging by supplying heat, each of the heat-sealing means comprising a sheet gripper which is provided with a heating body, the device furthermore comprising means for heating the heating body of at least one of the heat-sealing means, as well as means for measuring the temperature of that heating body and means for controlling the heating means based on the measuring means, the measuring means being arranged in a stationary position relative to the packaging means.
- a packaging conveyor having a series of holders for holding each item and its associated packaging sheet securely during conveying,
- the measuring means can be arranged, for example outside the moving parts of the packaging conveyor, which measuring means are generally accommodated on a rotation drum. Fewer components are required for measuring the temperature.

- the distribution disc 7 has a relatively large surface, on which the lollipops supplied in bulk can be spread out.
- the distribution disc 7 is provided on the edge with holding spaces for the head of the lollipops and with radially outwardly extending slots for the sticks thereof.
- the lollipops with lollipop sticks are brought into an orientation with the sticks directed radially outwardly and then retained with the aid of means (not shown), which are known per se.
- Stick clamps are arranged on the second process wheel, which grasp the lollipops by their sticks and lift them from the distribution disc 7.
- a third process wheel 9 Downstream of the second process wheel 8, a third process wheel 9 is arranged which rotates in the direction E about the centre axis S3.
- a series of lollipop holders is arranged on the third process wheel 9, at each of which a film/foil sheet clamp is positioned.
- a film/foil feed station 10 is positioned at the third process wheel 9, in which a roll of film/foil sheet material can be placed and unwound and can be cut into separate sheets Fi, delivered intermittently to the third process wheel 9.
- a fourth process wheel 11 Downstream of the third process wheel 9, viewed in processing direction, a fourth process wheel 11 is disposed, which is rotatably driven in the direction F about the centre axis S4.
- the fourth process wheel 11 is provided with a series of co-rotating lollipop holders 50 and a series of co-rotating wrappers, as well as heat-sealing means for heat-sealing the two twisted ends of the film/foil packaging sheet on the lollipop .
- Lollipops packaged in the fourth process wheel 11 are passed on to a discharge wheel 12, which rotates in the direction G and can deliver the lollipops to a discharge 14 in order for them to be discharged in the direction J.
- Fig. IA one of the pairs of wrappers 20/30 of the fourth process wheel 11 is illustrated in side view. It will be understood that the fourth process wheel 11 is situated at right angles to the plane of the drawing, the illustrated lollipop L with the stick Si being situated parallel to the centre axis S4.
- the lollipop holders 50 are illustrated diagrammatically and are clamped radially on the lollipop head Ki by means of clamping jaws 50a, 50b while clamping the film/foil sheet Fi present in tubular form in between.
- the longitudinal seam of the film/foil sheet runs parallel to the stick Si.
- the left-hand wrapper 20 comprises a holder 28 with two arms 21a, 21b, which are pivotably attached to the holder 28 at 22a, 22b and are provided with toothings 23a, 23b at that end. In a manner known per se, these toothings are in engagement with a toothed rack (not shown) , which can be moved to and fro in the direction parallel to the stick Si. As a result of this movement, the arms 21a, 21b will rotate in the direction L, between a radially projecting, non- operating position, illustrated in the figure, and a closed, operating position.
- the wrapping arms 21a, 21b are provided with clamping panels 24a, 24b, with which a film/foil tube can be clamped flat.
- the wrapper 30 is constructed in a similar way and has a holder 38 with two wrapping arms 31a, 31b, which are pivotably attached to the holder 38 at the location of pivots 32a, 32b, and are there provided with toothings 33a, 33b, which engage again in a toothed rack in a manner known per se, which toothed rack can be moved to and fro in a direction parallel to the stick Si.
- the wrapping arms 31a, 31b are provided with clamping panels 34a, 34b, with which a film/foil tube can be clamped flat.
- Both holders 28, 38 are rotatable in the direction K, about a centre axis parallel to the stick Si, and to this end are provided with toothed wheels 25, 35, the teeth 26, 36 of which are in permanent engagement with an inner toothing 41 on a fixedly arranged ring 40, see Fig. 2A (for toothed wheel 25: toothed wheel 35 is driven in a similar fashion) .
- the holders 28, 38 are mounted so as to be rotatable about their centre axes in the rotating section of the fourth process wheel 11. During rotation of the fourth process wheel 11, the teeth 26, 36 of the toothed wheels 25, 35 will therefore run along the fixed annular toothing 41, so that the holders 28, 38 and thus the wrappers 20, 30 are rotated in the direction K.
- twisting arms 21a, 21b remain in the projecting position, they will follow a garland-like path V during the rotation, as is illustrated diagrammatically in Fig. 2.
- the number of such turning positions can be larger or smaller, depending on the ratio of the diameter of the toothings 41 and 26, 36.
- a coil 62 is arranged at the location of one of these turning positions of arms 21b.
- This coil 62 forms part of a heating device 60, placed in a stationary position near the fourth process wheel 11, as illustrated diagrammatically in Fig. 1.
- the coil 62 forms part of an induction heating device 60, illustrated in more detail in Fig. 2, comprising an induction heating unit 67, controlled by a control unit 66, from where a tube 63a, b runs which forms a coil 62 with turns 64.
- the coil 62 is directed exactly radially relative to the fourth process wheel 11.
- the tube 63 is made of copper, electrically conductive material, and is of hollow construction, so that a coolant flow can run via tube leg 63a, the coil 62 and back via tube leg 63b.
- the tubes 63a, 63b continue on the other end of the induction device 60, with tubes 65a, 65b, which lead to an induction device 61, where the coolant is cooled in the tube.
- the cooling unit 61 is electrically insulated from the induction heating unit 67.
- the coil 62 is positioned such that it can accommodate the clamping panel 24b of the wrapper 20 in its entirety, without contacting it. This is illustrated in more detail in Fig. 2B.
- the clamping panel 24b As can be seen in Figs. 3A-C, the clamping panel 24b, attached to the wrapping arm 21b, is provided with a metal insert 27b, fixedly clamped in a slot 29 made in the clamping panel 24b.
- the clamping panel 24b is furthermore made from a suitable plastic material.
- the metal insert 27b can be made from RVS430, ferritic stainless steel.
- the insert 27b is provided with a slot 27c for a lollipop stick, similar to the clamping panel 24a opposite.
- the packaging device 1 furthermore comprises a fixedly arranged infrared sensor 80, which is positioned on the periphery of the movement path such that the clamping panel 24b comes within its measuring range.
- the infrared sensor 80 is connected by a line 81 to the control unit 66 in order to emit measurement signals thereto which are indicative of the temperature of the insert 27b of the clamping panel 24b. These are stored in a shift register 82 in the control unit 66. As illustrated in Fig. 5, the infrared sensor 80 is arranged four positions upstream of the heating coil
- the infrared sensor 80 could for example also be arranged two positions further downstream if that does not impede the introduction of the packaging film/foil and the lollipop.
- the number of positions of the shift register 82 is equal to that number of positions, in this example therefore four positions.
- Fig. 5A shows the - in this case 10 - pairs of clamping panels 24a, b (positions a-j), with the direction of movement F being shown by way of indication.
- the clamping panel pair 24a, b of position f is then at the coil 62.
- a new measurement is taken on a clamping panel 24b.
- the control unit 66 is connected via input 72 to a control panel 71 with which the desired value for the temperature for the insert 27b, the heating body can be input into the control unit 66.
- the control unit 66 furthermore comprises a port 69a, for the line 81 leading from the infrared sensor 80 to the shift register 82.
- the port 69b is connected to an induction heating unit 67 which activates the coil 62 via line 63a, b.
- control unit 66 in which every measured value can be stored, at least until the next heating cycle of the respective clamping jaw, it is thus in principle possible to heat each clamping jaw separately up to a desired temperature according to an individually adapted control of the heating means, in this case using the induction coil.
- the induction heating unit 67 in order to energize the induction coil 62 at the observed differential temperature, based on a comparison of the measured value stored in the shift register 82 for position b and the desired value, for example 13O 0 C, proportionally, according to power and/or time.
- Fig. 5B is identical to Fig. 5A except that it has been extended by a shift register 70, in which one or more values can be stored via port 68b for each position a-j relating to the state of the control unit, in particular the history of the state of the control system.
- the control unit 66 is able to read out the relevant information via port 68a and use it for the control of the induction heating device 67, also on the basis of the most recent measured value of infrared sensor 80 for the relevant position.
- Value (s) representative of the respective control of the induction heating device 67 are stored in the shift register 70, for use in later cycles for the relevant position .
- each separate clamping panel 24b with an insert 27b can be achieved, not only with minimum deviations between the positions themselves, but also for each position over time .
- the lollipops with film/foil sheet hanging from the head are received in the holders 50a, b of the fourth process wheel 11.
- the film/foil sheet can be folded around the head to form a tube.
- the two wrappers 20, 30 are not yet active, but hot air pressed into section II, which, using means (not shown) , such as pipes bent in accordance with the path of the film/foil sheet around the head, will be delivered in a directed manner to the portion of the film/foil sheet which protrudes from the head on the end remote from the stick, will ensure that the film/foil sheet is heated on the side of the head remote from the sticks.
- the clamping panel 24b of the wrapper 20, which follows the path V, will move into and out of the coil 62.
- the induction coil 62 is energized electrically by the induction heating device 60, as a result of which a magnetic field is generated within the coil 62.
- the magnetic field will heat the metal insert 27b sufficiently for sealing purposes.
- the clamping panels 24a, 24b and 34a, 34b clamping the film/foil sheet F 1 such that it is flat.
- the clamps 50a, 50b By the engagement with the associated annular toothed racks (41), they are rotated continuously, while the film/foil tube with the lollipop head is held securely and permanently by the clamps 50a, 50b.
- twisted or wrapped film/foil tube sections are formed on both ends of the lollipop head K, the heated insert 27b ensuring that the film/foil material is heat-sealed locally at the stick Si.
- the preheated film/foil material will ensure that the twisted film/foil material between the clamping panels 34a, 34b and the head Ki is heat-sealed. This is the end of the sealing and wrapping section III, and the double-twisted, packaged lollipop can be dispensed in section IV.
- the metal insert 27b is insulated by the plastic material against the clamping panel 24b towards the sides which are not to be used, it will be possible to retain the heat in the insert 27b to a large degree and during the next insertion in the induction coil 62, it will only need to be reheated, as has been explained above.
- the diffusion of heat in the drum is in this case limited to a minimum.
