Definitions
- the present invention relates to a method for centring the print on one face of the wrapper of packs of items.
- the need is known for putting printed information on the pack wrapper, for example marketing or advertising information.
- the bundles of items are normally packaged in a wrapper made using a sheet of material such as cellophane.
- the sheet of cellophane is taken from a web which is unwound from a reel, folded into the shape of a tube and sealed longitudinally.
- the tube obtained in this way is sealed transversally to form a sort of bag designed to receive the bundle of items to be packaged.
- the wrapper is then closed by sealing and cutting the sheet of cellophane at the back of the items packaged, at the same time forming the base of the wrapper for the subsequent pack.
- the print is applied to the cellophane web, at suitable intervals, so that it is located on a predetermined face of the wrapper produced.
- the print may be in any position considered suitable, except, obviously, in the wrapper sealing zone. Often, for example, the print is present on one side of the pack so that it is visible when the packs are arranged on a pallet or stored using other methods.
- the print applied to the cellophane web may have an error which is reproduced on the pack or the error, for example print which is shifted so that it is early or late relative to the condition initially required, may occur during the packaging steps.
- the aim of the present invention is to overcome the above-mentioned disadvantage by providing a method which allows the automatic centring of the print on a predetermined face of the wrapper of packs of items.

- the folder part 4 constitutes a tubular guide 40 with a transversal profile substantially corresponding to the dimensions of the items 2 to be packaged.
- Longitudinal sealing means 42 are attached to the folder part 4. The sealing means are designed to seal the tube shaped cellophane web 30 closed.
- the longitudinal seal line of the tube shaped folded web 30 is normally positioned at the centre line of the pack.
- the items 2 are fed to a lift part 5 which transfers them to a raised position coplanar with the base of the tubular guide 40 of the folder part 4.
- a pusher part 6, driven by an actuator 60, on a horizontal axis, is designed to move the items 2 in a direction longitudinal to the folder part 4.

- the lift part 5 moves to its raised position, in which the first bundle 2 is coplanar with the base of the tubular guide 40 of the folder part 4.
- the cellophane web 30 folded into a tube shape was previously stretched, for example manually, at the shaped opening 41.

- the second operation in the initial calibration step involves moving the pusher part 6 further forward, again with the jog control, until it reaches the ideal end of stroke point, corresponding to the reference line "Ao" in Figure 4.
- the sealers 8 move towards one another, closing the first wrapper 3 produced in this way, separated from the tubular web by the simultaneous action of the cutting means 9, and at the same time closing the base of the wrapper designed to receive the next bundle of items 2 (see Figure 1).
- the pack produced rests on a table 14 at the folder part 4 outfeed, downstream of the sealers 8.
- the normal automatic cycle for packaging the items 2 can then be started, during which the method disclosed is designed to check the position of the print in each wrapper as they are produced and to intervene with suitable corrections if positioning errors are encountered.
- the bundles of items 2 to be packaged are transferred from the lift part 5 in the raised position and pushed by the pusher part 6 into the tube shaped cellophane web at the wrapping station.
- the bundle of items 2 to be packaged drags the cellophane web 30 which is wrapped around it.
- the pusher part 6 stroke continues until the first position (characteristic P) is reached ( Figure 3A). If the detector means 7 detect the first characteristic position P correctly, it must coincide with the reading of a reference section by the sensor 10. In such cases, the control means 11, verifying a match, issue the actuator 60 command so that the pusher part 6 completes its stroke to the point previously set (reference line "Ao", Figure 4).

- Said correction is made in real time, intervening to restore the correct position starting with the next pack.
- Said correction may be applied gradually over several successive packs, so as to avoid unwanted effects on the tension of the wrapper.

Description
- The present invention relates to a method for centring the print on one face of the wrapper of packs of items.
- In the sector for packaging items in bundles the need is known for putting printed information on the pack wrapper, for example marketing or advertising information. The bundles of items are normally packaged in a wrapper made using a sheet of material such as cellophane. In a known solution, the sheet of cellophane is taken from a web which is unwound from a reel, folded into the shape of a tube and sealed longitudinally. The tube obtained in this way is sealed transversally to form a sort of bag designed to receive the bundle of items to be packaged. The wrapper is then closed by sealing and cutting the sheet of cellophane at the back of the items packaged, at the same time forming the base of the wrapper for the subsequent pack.
- The print is applied to the cellophane web, at suitable intervals, so that it is located on a predetermined face of the wrapper produced. The print may be in any position considered suitable, except, obviously, in the wrapper sealing zone. Often, for example, the print is present on one side of the pack so that it is visible when the packs are arranged on a pallet or stored using other methods.
- In the specified sector, there is the problem of guaranteeing correct positioning of the print on the predetermined face of the wrapper, within a predetermined size range. The print applied to the cellophane web may have an error which is reproduced on the pack or the error, for example print which is shifted so that it is early or late relative to the condition initially required, may occur during the packaging steps.
- Obviously, such print positioning errors, although limited in themselves, tend to add up as the number of packs produced rises, since the print gradually shifts relative to the required position, until it is in an unacceptable position. It is also known from
document EP 0 761 546 an apparatus for use with a web having printed thereon bar codes each identifying a container manufacturer, product, etc. and arranged longitudinally of the web at a spacing corresponding to one container, for positioning each of the bar codes in a specified position. The positioning apparatus comprises a feeder drivable by a main shaft for transporting the web via the specified position, a detector for detecting the angle of rotation of the main shaft upon the bar code moving past the specified position, and a calculating unit for calculating the deviation of the angle detected by the detector. - The aim of the present invention is to overcome the above-mentioned disadvantage by providing a method which allows the automatic centring of the print on a predetermined face of the wrapper of packs of items.
- Another aim of the present invention is to provide a method which allows the real time correction of any errors.
- Yet another aim of the present invention is to provide a method which allows the above-mentioned print centring by means of an operating structure which has a simple design with reliable and versatile operation.
- The aforesaid aims are achieved as described in the claims.
- The features of the invention are now described with reference to the accompanying drawings, in which:
- Figure 1 is a schematic side view of a machine for packaging items in bundles, centring the print according to the method disclosed;
- Figure 2 is a corresponding plan view;
- Figures 3 and 4 illustrate the above-mentioned side view of the machine in successive operating steps of the method according to the present invention;
- Figure 3A illustrates an operating mode of the method relative to an initial calibration step;
- Figure 3B illustrates an alternative embodiment of the mode illustrated in Figure 3A.
- With particular reference to the accompanying drawings, the numeral 1 denotes as a whole a machine for
packaging items 2 in bundles inside awrapper 3 produced using a sheet of material such as cellophane. The sheet of cellophane is obtained form aweb 30 which is unwound from areel 31 and engages with a set oftensioning rollers 13. - At appropriate intervals, the
cellophane web 30 has a set of printed information. Said print includes a reference section (mark) designed to be detected by suitable sensor means 10, for example of the photocell type, located downstream of thereel 31. The signal detected by the sensor means 10 is sent to electronic control means 11. - The
cellophane web 30 is fed to afolder part 4 with ashaped opening 41 designed to fold the web 30 (see in particular Figure 2) into the shape of a tube. Thefolder part 4 constitutes atubular guide 40 with a transversal profile substantially corresponding to the dimensions of theitems 2 to be packaged. Longitudinal sealing means 42 are attached to thefolder part 4. The sealing means are designed to seal the tube shapedcellophane web 30 closed. The longitudinal seal line of the tube shaped foldedweb 30 is normally positioned at the centre line of the pack. - The
items 2 are fed to alift part 5 which transfers them to a raised position coplanar with the base of thetubular guide 40 of thefolder part 4. Apusher part 6, driven by anactuator 60, on a horizontal axis, is designed to move theitems 2 in a direction longitudinal to thefolder part 4. This movement of thepusher part 6 is controlled, as is better explained below, by detector means 7. The detector means 7 are connected to the electronic control means 11, which suitably control thepusher part 6actuator 60. In particular, the detector means 7 are designed to compare the movement of thepusher part 6 with the machine cycle degrees. - At the
folder part 4 outfeed there are transversal sealing means 8 designed to transversally seal thecellophane web 30 folded into the shape of a tube. Cutting means 9 are attached to the sealing means 8 and simultaneously cut theweb 30 along a cutting line in the middle of two adjacent seal lines. - The method disclosed for centring print on the
wrapper 3 of packs ofitems 2 involves an initial calibration step, with which reference parameters are saved on the control means 11, as explained below. The first operation in the calibration step consists of predetermining the correct centring of a first print in a first wrapper at the wrapping station formed by the folder means 4, which are designed to fold thecellophane web 30 into a tube shape, and by the longitudinal sealing means 42. - A manual jog control is used to operate the machine to feed a first bundle of
items 2 to thelift part 5, against apanel 15. - Continuing operation, the
lift part 5 moves to its raised position, in which thefirst bundle 2 is coplanar with the base of thetubular guide 40 of thefolder part 4. - Inside the tubular guide the
cellophane web 30 folded into a tube shape was previously stretched, for example manually, at theshaped opening 41. The tube obtained in this way is sealed transversally by thesealers 8 to form a sort of bag designed to receive the above-mentioned bundle ofitems 2 to be packaged. - It should be noticed that in this preparation operation the
web 30 is fed into thetubular guide 40 until a first print applied to theweb 30 is in the desired position, relative to the dimensions of the bundle of items to be packaged. Said print position is upstream of thesealers 8. - The first bundle of
items 2 transferred to the raised position is then moved longitudinally, by thepusher part 6, into the first partially formedwrapper 3 in the wrapping station consisting of the folder means 4. - The forward movement of the
pusher part 6 moves the first bundle ofitems 2 until it is close to the transversal seal which forms the base of the wrapper. The machine parts open thesealers 8 in a suitably synchronised fashion. - Continuing the
pusher part 6 forward movement, the first bundle ofitems 2 drags theweb 30, unwinding it from thereel 31. As a result of this forward movement, a reference section of a subsequent print applied to theweb 30 is detected by the photocell sensor 10 (line "O" in Figure 3A). - In this particular situation, the detector means 7 acquire the parameters relative to the position of the pusher part 6 (first characteristic position P; see Figure 3A), as well as the corresponding machine cycle degrees. The data is recorded in the control means 11 which, at this point, create a triple link in the memory between the
pusher 6 first characteristic position P, the machine cycle degrees and simultaneous detection of the reference section, which correspond to print centring in the wrapper. - The second operation in the initial calibration step involves moving the
pusher part 6 further forward, again with the jog control, until it reaches the ideal end of stroke point, corresponding to the reference line "Ao" in Figure 4. - Said point is established in such a way that the subsequent closure of the
sealers 8 creates afirst wrapper 3 with the desired tension characteristics. Thepusher 6 end of stroke position "Ao" is also saved by the control means 11 together with the relative machine cycle degrees value. - Continuing with manual operation, there is a suitably synchronised backward movement of the pusher, the
sealers 8 move towards one another, closing thefirst wrapper 3 produced in this way, separated from the tubular web by the simultaneous action of thecutting means 9, and at the same time closing the base of the wrapper designed to receive the next bundle of items 2 (see Figure 1). The pack produced rests on a table 14 at thefolder part 4 outfeed, downstream of thesealers 8. - The normal automatic cycle for packaging the
items 2 can then be started, during which the method disclosed is designed to check the position of the print in each wrapper as they are produced and to intervene with suitable corrections if positioning errors are encountered. In a suitably synchronised fashion, the bundles ofitems 2 to be packaged are transferred from thelift part 5 in the raised position and pushed by thepusher part 6 into the tube shaped cellophane web at the wrapping station. During thepusher part 6 stroke, the bundle ofitems 2 to be packaged drags thecellophane web 30 which is wrapped around it. - The
pusher part 6 stroke continues until the first position (characteristic P) is reached (Figure 3A). If the detector means 7 detect the first characteristic position P correctly, it must coincide with the reading of a reference section by thesensor 10. In such cases, the control means 11, verifying a match, issue theactuator 60 command so that thepusher part 6 completes its stroke to the point previously set (reference line "Ao", Figure 4). - Completion of the
pusher part 6 stroke also causes the pack previously produced to be unloaded from the table 14. - The cyclical comparison between the parameters detected by the
means 7 and thesensor 10 and those saved guarantees that the position of the print in the wrapper is correct when the correspondence between said parameters is verified. - The deviation of the print position relative to the predetermined position P is detected when the
sensor 10 detects the reference section early or late (lines 0+ and 0- in Figure 3) relative to the position in which the pusher part reaches the first characteristic position P. - The deviation value is combined with the relative machine cycle degrees, so as to check if it lies within a predetermined "range" in which a correction can be made with a single corrective movement.
- Said correction is made in real time, intervening to restore the correct position starting with the next pack.
- For example, if a print delay is detected (line "0-" in Figure 3) relative to the predetermined position P, a command to increase the
pusher 6 stroke (line "A+" in Figure 4) is automatically issued, causing a corresponding increased traction on the tubular cellophane web. If, on the other hand, early print is detected (line "0+" in Figure 3 in sensor 10) a command is issued to reduce thepusher 6 stroke (line "A-" in Figure 4), therefore causing reduced traction on the web. - Said correction may be applied gradually over several successive packs, so as to avoid unwanted effects on the tension of the wrapper.
- In an alternative embodiment of the method, in the first operation of the initial calibration step the position of the
pusher part 6 in which the first bundle ofitems 2 is close to the base of the wrapper, before thesealers 8 open (position P* in Figure 3B) is saved. - The
photocell sensor 10 is simultaneously adjusted one way or the other (arrow F) to align it with a reference section of a print, after the one centred on the wrapper. - As already indicated, this establishes a triple link of data saved in the control means 11 which, in the normal machine operating cycle, allows correct print centring to be checked and, if necessary, definition of the extent of the correction to be applied in the
subsequent pusher part 6 end of stroke position. - Therefore, the method disclosed achieves the aim of automatically maintaining print centring on a predetermined face of the wrapper of items to be packaged in bundles, within a predetermined tolerance "range".
- It should be noticed that the correction of any print centring errors on the cellophane web is performed in real time without compromising normal machine operation.
- One advantage of the invention is the fact that the above-mentioned print centring, according to the method disclosed, is performed by an operating structure with a simple design and reliable, versatile operation.
- It shall be understood that the above is described by way of example and in a non-restrictive way, therefore, any alternative construction variations do not depart from the inventive concept of the present technical solution, as described above and in the claims herein.
