Definitions

  • the invention is a machine for wrapping articles with stretch films, specifically designed to wrap products by using a portion of stretch film and sealing it under the product after wrapping it.
  • the stretch film for the article to be wrapped is supplied from a roll and there are means to control the correct position of the article and the stretch film to be wrapped around it. Also for folding and final sealing of the stretch film underneath the article being wrapped.
  • the machine is of the type where the articles to be wrapped enter and leave on the same side with the aim of adding, if necessary, weighing and labelling equipment to the wrapping machine.
  • the aim of the invention is that of providing a wrapping machine for articles, such as trays containing products of any kind.
  • a programmable microprocessor By controlling all the devices and means which participate in the process with a programmable microprocessor. Consequently, depending on its size the article will be correctly placed on the elevator and the portion of stretch film required for the exact size of the article will be supplied and cut.
  • the microprocessor of the machine controls placing the article on the elevator, depending on its size. Along with controlling the portion of the film needed for wrapping it, as well as the stretching, or tightening and appropriate synchronisation of the movements of all the mechanisms and elements which take part in the wrapping operation.
  • the machine referred to has been designed to solve all these problems. This is achieved by programming the different movements and operational phases, to vary based on the size of the article. By controlling the placement on the elevator of the article which is to be wrapped, as well as the size of the film required to wrap it. Also the movements of the film feeding clamp, the folding mechanisms and the cutting blade so that everything is controlled to work in accordance with the size of the article.
  • one of the characteristics of the invention is that in accordance with its size the article will be placed on the corresponding elevator in a position specified by the microprocessor, so that the film distribution in the wrapping process will achieve a controlled overlapping and sealing of the film on the bottom of the article for a better appearance and seal.
  • the article can be placed in any position on the elevator, it is possible to choose the best film distribution for the wrapping process.
  • the elevator itself, which traditionally consists of a series of supports with collapsible heads, designed to keep the articles in place when the elevating and wrapping operations are carried out. This has been redesigned by eliminating springs and any other mechanisms, necessary to reset the heads after they have been collapsed.
  • the body of the support is to be made of flexible plastic material and conveniently fixed to a head, also made of plastic, by means of a neck-like narrowing to cause the movements of collapsing and resetting necessary for the normal functioning of the folding mechanisms.
  • the film-feeding clamp has a variable longitudinal movement to extract a portion of the film in proportion to the corresponding transverse dimension (width) of the article ready to be wrapped. In each case the amount of film fed is just enough to complete the last fold of the folding operation.
  • the movement of the film-feeding clamp is variable in the direction of the product exit and moves below the sealing belt. This movement is very important because it makes it possible to control the final tightening of the film during the last folding operation.
  • the film-feeding clamp will tighten the film in proportion to its stretchable limits, and the tautness required to cut it.
  • the clamping action of the film-feeding clamp is performed in three areas, one central and two side sections.
  • the film when being fed is clamped at the same time in all three areas. Subsequently it will be released, first the lateral areas for easier lateral folding, i. e., to allow the exterior film areas to be free and reduce over stretching the film during the process of folding them under the article, while the central part is held in place by the clamp until final folding.
  • this wrapping machine includes side clamps, which clamp the film when it is extended and taut in the longitudinal sense. These clamps can be moved laterally to stretch the film transversely. This can be programmed for the width of the film used and the length of the article to be wrapped. With regard to the film the distance of these side clamps is variable so as to be able to hold the film by its edges whatever the width of the film being fed from the roll. In the transverse stretching direction, however, the side clamps are in a controlled position so that the degree of prestretch is always the same, regardless of the film width.
  • a further uniqueness of the machine is that the corresponding film unwind has a brake incorporated for the activation and deactivation which is calculated according to the article which is to be wrapped. This brake remains activated until the top of the rising article touches the film. At this moment the brake becomes deactivated, but the article continues to rise and removes an additional amount of film from the roll. Then the brake is activated again before the elevator completes its stroke in order to obtain the tautness necessary for the film to be cut.
  • the exact time of the brake activation will be specified by the program in accordance with the article being wrapped, and the amount of film required. This ensures the optimum use of the lowest amount of film possible for each wrapping. In addition, tray and film breakage is avoided by not surpassing their limits of elasticity. This allows the wrapping to take place with optimum tautness for the best appearance and preparation of the wrapped article.
  • the wrapping process begins with the introduction of the side folding mechanism and a rear folding mechanism. This means that for side folding the tautness of the film is maintained by the timing of the mechanised film holding system which will be deactivated at the exact moment when the side folding mechanisms press on the film and the folding begins.
  • Activating the movement of the side clamps, that hold the pre-stretched film can be programmed for both clamps to start their inward movement simultaneously with the side folding mechanisms and the side clamp closing and opening position being, programmed according to the length of the product to be wrapped.
  • Folding of the last part of the film or the last folding i. e., the portion of film situated between the feeding clamp and the sealing belt.
  • the feeding clamp has to release the film still held in its central area, while the movement of the expelling device and that of the clamp are synchronised by the microprocessor.
  • the central folding device is incorporated in the expelling mechanism. This folding device carries out the last folding operation as the expelling mechanism transfers the article to sealing belt.
  • the machine has means which allow the (leading edge) free end of the film from the rolls to be positioned rapidly and correctly in alignment with the corresponding film feeding device.
  • the terms length and width have a particular meaning in the packaging field as they relate to a trayed product to be wrapped.
  • the long dimension of the tray is normally called its length and the short dimension its width.
  • the trayed product is, however, generally inserted with its long dimension entering first, so that the length of the trayed product is in the same direction as the width of the film, while its width, or transverse direction, is in the longitudinal direction of the film.
  • the heated sealing belt can be relocated and a transfer system for the article that will move it to lateral position upon exiting can be inserted prior to the sealing belt. This would be done to automate the removal of the trays, allow the installation of automated weighing-labelling equipment, or, an automated labelling device.
  • FIG. 1 shows that the machine has two rolls (5), each with a particular type or size of film chosen in accordance with the type and or length of the article or product which is to be wrapped.
  • the film (4) passes through a film distributor consisting of a comb (6) which as part of a general device can be tilted, and in turn includes means of positioning the free end of the film (4) into the distributor comb (6), both in the case of a new roll (5) when it is put in the machine and when the film needs to be reinserted.
  • a film distributor consisting of a comb (6) which as part of a general device can be tilted, and in turn includes means of positioning the free end of the film (4) into the distributor comb (6), both in the case of a new roll (5) when it is put in the machine and when the film needs to be reinserted.
  • the device (7) can be tilted around the axis (8) and remains in its operating position by means of the action of an automatic actuator (9) the shaft of which has a support end (10) for a shaft (11) belonging to the general body of the device (7).
  • the arrangement is such that when the actuator (9) is in operation, its shaft is extended and therefore pushed upwards, and supported by the actuator end (10), the special feature being that the distributor consists of a roller (12) pressing on a roller (13) when it is in the closed position described before, i. e., the device (7) pushed upwards by means of the actuator (9), which forces the film (4) to pass between the roller (12) and the roller (13).
  • the actuator (9) When the free end of the film (4) is to be placed in the distributor comb (6) in order to put in a new roll of film, the actuator (9) is to be deactivated by retracting its shaft and therefore letting the device (7) tilt, which frees the film (4) from being pressed between the roller (12) and the roller (13) and allows for easy insertion and film changing.
  • the roller (13) is fitted on a support (14) which at the end opposite to that of the roller (13) holds another roller (15) which duly keeps the film (4) in position until it has been cut by the cutting blade (16), as shown in Fig. 1.
  • the machine has a film feeding clamp (17) which can be moved forward and backward and which is situated in the area opposite that of the rolls (5) below the sealing belt (22) so that the article (1) elevated by the elevator (3) remains under the film, held between the film feeding clamp (17) and the film distributor area described earlier.
  • the article (1) which is to be wrapped enters the machine conveyed by the feeding belt mentioned before and passes by a sensor barrier (18) which checks the size of the article (1) and transmits the data to the corresponding microprocessor where the corresponding control orders are given for the movements of all the means and devices of which the machine consists.

  • the film feeding clamp (17) feeds a variable portion of film (4) in proportion to the size of the article (1).
  • it is pre-stretched depending on its characteristics, and it must be remembered that in accordance with the article to be wrapped the machine will choose either type of film from either roll (5).
  • the movement of the film feeding clamp (17) is variable and its movement can be programmed in the exit direction of the product.
  • This clamp moves underneath the sealing belt (22).
  • the side clamps (19) hold the film (4) by the edges and execute transverse stretching programmed according the characteristics of the film.
  • transverse stretching is always the same, regardless of the width of the initial film, i. e., the movement of the clamps (19) in the direction of stretching is always the same, while it is variable in its starting point and corresponds to the length of the tray and the width of the film.
  • an impulse counter sends the signals to the microprocessor which informs the program of the position reached by the lifter.
  • the tray or its equivalent, i. e., the top part of the product contained in it, touches the film sheet (4), a brake in the corresponding roll-unwind is deactivated so as to feed some additional film from the roll (5).
  • the brake is activated again just prior the article (1) reaching its highest point of elevation so as to tighten the film for appropriate stretch and tautness in the cutting operation.
  • the rear folding device (21) folds the portion of the film (4) between the article (1) and the cutting blade (16), while the cutting time takes place according to the size of the article (1) and the type of film, to properly stretch and cut the film.
  • the central folding device (21) When cutting has taken place, the central folding device (21) continues its forward movement and transports the article (1) to the sealing belt (22) with the aid of the exiting device mounted on it (21) so the film, can be now totally wrapped around the article (1), and is sealed by the belt (22) which has a heating means for the corresponding sealing action.
  • the exiting device mounted on the central folding device (21) executes pushing the article (1) towards the sealing belt.
  • the exiting device is set into motion by an actuator (24), as shown schematically in Fig. 7.
  • the central folding device is designed for folding the part of the film situated between the interior end of the article and the cutting blade and the transfer of the article to the sealing belt (22), while the last or final folding takes place.
