Description

The present invention relates to a high-speed trace kinpack packaging machine that continuously skin-packs objects to be packaged stored in, for example, a plastic tray or a paper or metal container welded with a heat sealable material on the surface.

  A skin pack is a packaging method in which a heat-softened cover film is stretched from above a tray that contains articles to be packaged, and the cover film is brought into close contact with the surface of the package to be vacuum packaged (see Patent Document 1).

  Patent Document 1 discloses a vacuum packaging method for producing the skin pack package. In the vacuum packaging method of Patent Document 1, the pressure around the plastic tray containing the food is set to a negative pressure in the pressure-resistant chamber, and the cover film is heated and softened with a first hot plate, and then the pressure-resistant chamber. The interior is returned to atmospheric pressure, and the softened cover film is pressed against the tray and the upper surface of the food at the atmospheric pressure to form a vacuum package.

The vacuum packaging apparatus disclosed in Patent Document 1 includes a pressure-resistant chamber made up of an upper box and a lower box in a first process area, and a lower sealing table and an upper second heating plate in the second process area. Provided. In addition, the roll film supported on the horizontal horizontal shaft is pulled out as a belt-like cover film by the winding force of the reel, and the plastic tray containing the packaged items is carried into the pressure-resistant chamber with a supply device. It is configured to

  The pressure-resistant chamber in the first process area has a seal stand disposed inside the lower box, and a support plate that moves up and down while supporting the tray from below in the seal stand. The support plate lowers the tray and moves the tray. The flange can be attached on the sealing table. Moreover, the 1st hot platen installed in the upper box is the reverse saddle shape of the same outline as the flange of a tray, and can press a cover film to a flange with the motive power of an actuator. In addition, a receiving groove for the upper cutting blade is formed on the peripheral edge of the flange in the sealing base.

  The lower box of the first process area is pushed up so as to be in close contact with the upper box, and the air in both the upper and lower boxes is sucked by a vacuum pump, and then the first hot platen is lowered and the cover film is pressed against the upper surface of the flange. Further, the lower box is pushed up against the reaction force of the upper coil spring, and the cover film is cut with a cutting blade around the flange. Thereafter, when the atmospheric pressure is reduced in both the upper and lower boxes, the cover film heated and softened by the first hot platen is stretched and is in close contact with the tray and the items to be packaged therein.

  The tray, to which the cover film is closely attached, is transferred onto the seal stage in the second process area by means of conveying, and the flange portion of the tray is seated. In the reverse saddle type second heating plate, the seal part at the lower edge has the same contour as the flange, and the seal part is notched to form a stealing part, and the notch stealing part is a part of the cover film. A weakly welded part is formed. The flange on the lower seal stand and the cover film are clamped and welded with a force smaller than the clamping pressure by the first hot platen.

  The vacuum packaging device of Patent Document 1 performs vacuum suction, sealing, cooling, and trimming in a pressure-resistant chamber in the first process area, and in the second process area, leaves a weakly welded part on the periphery of the cover film. Is welded to the flange of the tray.

However, in the first process area, the lower box of the first process area is pushed up so as to be in close contact with the upper box, and the air in both the upper and lower boxes is sucked by a vacuum pump. Unless this is completed, it is not possible to move on to the next tray vacuum packaging operation. Thus, since the vacuum packaging apparatus of the said patent document 1 cannot advance work continuously, work efficiency does not go up. Conventionally, the skin pack packaging work has also been performed in the batch-type vacuum packaging apparatus of Patent Document 2, but the efficiency is further poor.

In a high-speed model of a general tray packaging machine, a sealing device, a cooling device, and a trimming device integrally perform box motion motion. However, a plurality of trays (for example, 2 rows in the transport direction, 3 rows in total, 6 in total) ) Support the box motion motion, the cover film is sent at the pitch of the tray transport frame for three lines, not the tray size for each sheet. However, since the pitch between the lines of the tray transport frame is naturally determined, the cover film must be fed out in accordance with the tray transport frame even if the space between the lines is open. The amount is large and the yield is not good.

Hereinafter, the high-speed trace kinpack packaging machine of the present invention will be described with reference to the drawings. FIG. 1 is an overall plan view of the high-speed trace kinpack packaging machine of the present invention, and FIG. 2 is a front view thereof. The basic configuration of this type of packaging machine is a rotary vacuum packaging machine as disclosed in Patent Document 3.

The basic configuration of this high-speed trace kinpack packaging machine is that an oval endless chain 13 is stretched between a large-diameter gear 11 and a small-diameter gear 12 that are rotatably supported on the upper surface of the machine base 10. At the same time, a bottom plate 14 constituting the lower portion of the pressure chamber 18 is attached to the endless chain 13 at equal intervals, and each arm 16 projecting radially from the central main shaft 15 of the large-diameter gear 11 is attached to each of the arms 16. Ten lid members 17 forming the upper part are arranged at equal intervals along a circular orbit.

The pressure-resistant chamber 18 includes the bottom plate 14 supported by the endless chain 13 wound around the large-diameter gear 11, and the lid member supported via the arm 16 on a central main shaft 15 erected on the machine base 10. 17 and the rotational force of a motor (not shown) installed on the machine base 10 is transmitted to the large-diameter gear 11 so that the lid member 17 of the pressure-resistant chamber 18 rotates along a circular orbit. .

A wheel 21 at the lower end of the lifting pole 20 supported by a sleeve (not shown) installed on the large-diameter gear 11 is arranged on the machine base 10 as shown in FIG. Roll on the upper surface of the annular rail 22. The elevating pole 20 pushes up the arm 16 at a high portion of the upper surface of the annular rail 22 to open the lid member 17 away from the bottom plate 14, and conversely, at a lower portion of the annular rail 22, The elevating pole 20 is lowered and the lid member 17 closes the bottom plate 14. Thus, when the pressure-resistant chamber 18 is in a closed state, the air in the pressure-resistant chamber 18 is vacuumed.

  A recess for fitting the tray 19 is formed in the bottom plate 14 of the pressure-resistant chamber 18, and a flange 23 that supports the flange of the tray 19 is formed on the outer peripheral edge of the bottom plate 14. Further, an elevating bar 24 that pushes up the tray 19 from the bottom plate 14 is attached to the center bottom portion of the bottom plate 14 via a sleeve 25.

  A wheel 27 is provided at the lower end of the elevating rod 24 as shown on the left side of FIG. 6 so as to be easily understood, and it rolls on a rail 28 provided below the endless chain 13. It moves while moving. In the portion where the rail 28 is high, the elevating bar 24 rises and the upper support plate 29 lifts the tray 19. On the contrary, in the lower part of the rail 28, the elevating bar 24 is lowered and the tray 19 is fitted in the recess of the bottom plate 14.

A second heat sealing board 30 is provided on the lid 17 side of the pressure resistant chamber 18 so as to be movable up and down. The entire second heat sealing board 30 is heated to soften the cover film 31 and to weld the cover film 31 to the flange of the tray 19. The second heat sealing board 30 is operated by a diaphragm 32 provided at the upper center of the lid member 17. Further, a vacuum hose 33 communicating with a vacuum pump (not shown) is joined to the lid member 17 to generate a vacuum environment in the pressure resistant chamber 18.

The second heat seal board 30 is formed with a suction passage 26 penetrating the bottom board 14 side and the lid member 17 side. The cover film 31 is sucked from the side of the lid member 17 through the suction passage 26, and the cover film 31 is brought into contact with the second heat sealing board 30 to be softened by heating to enable skin pack packaging. On the other hand, the first heat sealing plate 61 described later serves only to temporarily seal the cover film 31, and the second heat sealing plate 30 serves to heat and soften the cover film 31 in order to skin pack. It is different from adding.

The high-speed trace kinpack wrapping machine of the present invention has the same basic configuration as the conventional rotary vacuum wrapping machine as described above, but the feature of the present invention is that the tray is placed in the linear conveyance section on the inlet side of the small-diameter gear 12. The alignment device 40, the synchronous supply device 50, and the temporary seal / trimming device 60 are arranged. In the following, these feature points will be described sequentially. First, the tray alignment device 40 will be described with reference to the drawings. However, the synchronous supply device 50 and the temporary seal / trimming device 60 including the tray alignment device 40 are not limited to the embodiments described below. Needless to say.

FIG. 3 is a partially enlarged view of FIG. 2, in which the tray alignment device 40 is shown. The tray aligning device 40 is configured to convey the tray 19 with a string-like endless belt conveyor 41 in which a plurality of string-like endless belts are stretched between pulleys 42, and align the tray 19 with a fork-shaped alignment stopper 43. ing.

The alignment stopper 43 is a retracted position that does not interfere with the transport of the tray 19 on the string-like endless belt conveyor 41 by the operation of the first air cylinder 44, and an alignment position that stops and aligns the tray 19 on the string-like endless belt conveyor 41. Leave in and out between. The tray 19 storing the objects to be packaged is aligned by the alignment stopper 43 while being transported by the string-like endless belt conveyor 41. As shown in FIG. 1, a total of four trays can stand by on the tray alignment device 40.

Although not shown in FIG. 1, a normal belt conveyor is disposed on the upstream side of the tray aligning device 40, and a tray storing the items to be packaged is randomly placed on the belt conveyor by an arrow 1. After being conveyed as shown, it is transferred onto the string-like endless belt conveyor 41 and aligned as described above.

As shown in FIG. 1, a synchronous supply device 50 is disposed on the downstream side of the tray alignment device 40. The synchronous supply device 50 is configured so that the tray 19 aligned by the tray alignment device 40 can be transferred to the bottom plate 14 of the pressure-resistant chamber 18 that circulates in the elliptical orbit, according to the moving speed of the bottom plate 14. Adjust the interval.

The synchronous supply device 50 is provided with hooks 53 that feed and lock the tray 19 at equal intervals, and a belt conveyor-like feeding device 51 that feeds the tray 19 in synchronization with the movement of the bottom plate 14 of the pressure-resistant chamber 18. The slide plate 52 is arranged at the lower part of the apparatus 51, and the tray 19 is placed on the slide plate 52 and slides downstream.

The slide plate 52 is composed of two strip-shaped plates arranged in parallel in a plan view, and a gap is provided between the plates. From this gap, the support plate 29 in the bottom plate 14 of the pressure-resistant chamber 18 rises while circling, and supports the bottom of the tray 19 that moves on the slide plate 52 in synchronization with the tray 19 from the slide plate 52 to the bottom plate 14 side. Can be transferred to.

As shown in FIG. 3, a lift device 70 for delivering the tray 19 is disposed between the tray aligning device 40 and the synchronous supply device 50. The lift device 70 is configured to deliver the tray 19 between the string-like endless belt conveyor 41 in the lower layer and the slide plate 52 in the upper layer.

In the lift device 70, a plurality of rectangular plate pieces as shown in FIG. 3 are erected in parallel between a plurality of string-like endless belts of a string-like endless belt conveyor 41, and a lower part is The rod of the second air cylinder 72 is joined. This lift plate 71 stops and waits for the tray 19 conveyed by the string-like endless belt at the upstream end surface (left end surface in FIG. 3).

While the lift plate 71 protrudes from above the string-like endless belt conveyor 41, the tray 19 upstream from the lift plate 71 is prevented from moving, but the lift plate 71 is lowered by the second air cylinder 72. Then, since the movement of the tray 19 is not hindered, the tray 19 can be conveyed by the string-like endless belt conveyor 41. In this way, the lift plate 71 rises only when it is detected that the tray 19 has been conveyed by the string-like endless belt conveyor 41 and has come to a position on the lift plate 71. The timing at which the lift plate 71 rises is achieved as follows, for example.

Since the hook 53 of the synchronous supply device 50 rotates at a constant speed mechanically in synchronization with the movement of the bottom plate 14 of the pressure-resistant chamber 18, the timing at which the lift plate 71 rises is the same as that of the hook 53 on the lift plate 71. The second air cylinder 72 is operated at a timing that does not interfere with the tray 19. That is, when it is time for the hook 53 to transport the next tray 19, the second air cylinder 72 is activated, and the lift plate 71 is raised with the tray 19 placed thereon. When the tray 19 rises to the same level as the slide plate 52, the hook 53 engages the tray 19 and transfers from the lift plate 71 onto the slide plate 52. As the lift plate 71 rises, the next tray 19 is stopped by the lift plate 71 and waits as shown in FIG.

Next, the temporary seal / trimming device 60 will be described with reference to FIGS. The lower part of FIG. 4 shows the bottom plate 14 of the pressure-resistant chamber 18. A tray 19 transferred from the synchronous supply device 50 is placed in the recess of the bottom plate 14. That is, since the rail 28 arranged on the lower outer periphery of the endless chain 13 in FIG. 2 becomes higher around the bottom of the slide plate 52, the elevating bar 24 provided on the bottom plate 14 is lifted, and at the same time the support plate 29 is as described above. The tray 19 is lifted from the gap between the slide plates 52. As shown in FIG. 4, the rail 28 is lowered when the slide plate 52 is interrupted. As shown in FIG. 4, the support plate 29 is lowered to accommodate the tray 19 in the recess of the bottom plate 14, and the flange of the tray 19 is placed on the flange 23. Attached.

The temporary sealing / trimming device 60 includes a first heat sealing board 61. The first heat sealing board 61 has the same contour as the flange of the tray 19 and is formed in an inverted bowl shape. The first heat sealing board 61 is pushed down by the lower power of an actuator (not shown), and the outer peripheral edge of the cover film 31 is pressed against the flange of the tray 19 with the outer peripheral edge of the first heat sealing board 61. Seal.

FIG. 4 illustrates a state in which an object to be packaged on the tray 19 is raised from the upper surface of the tray 19, but the first heat seal board 61 is in a state in which the object to be packaged does not rise from the upper surface of the tray 19. Can also be used. The first heat sealing board 61 sucks the cover film 31 upward from the suction passage 62 and expands it into a dome shape when the object to be packaged rises from the upper surface of the tray 19. Can be covered softly. If the entire first heat sealing board 61 is heated, the cover film 31 is heated and softened to help expansion.

On the contrary, the cover film 31 is temporarily sealed without sucking the cover film 31 from the suction passage 62 in a state where the packaged object is not raised. However, if the object to be packaged is swelled, it is not necessary to expand the cover film 31 into a dome shape if the object to be packaged can be skin-packed without being crushed even if the cover film 31 is pressed against the object to be packaged. The suction passage 62 is not an essential component for the first heat sealing board 61.

A notch 63 is formed in a part of the outer peripheral edge of the first heat seal board 61, and the notch 63 causes the air passage 34 that is not welded to a part of the cover film 31 as shown in FIG. 5. The air in the tray 19 can be extracted from the air passage 34.

A box-shaped trimming mechanism 65 provided with a cutting blade 64 on the outer peripheral edge is disposed so as to cover the first heat sealing board 61. A receiving groove 35 of the cutting blade 64 is provided around the periphery of the bottom plate 14. The cutting blade 64 of the trimming mechanism 65 is pushed into the receiving groove 35 by the lower power of the actuator, and the cover film 31 is formed in the shape of the tray 19. Trim along.

A roll film 66 supported by a horizontal shaft is disposed on the upper layer portion of the first heat seal board 61, and the belt-like cover film 31 is drawn out by the winding force of the winding reel 67, and accommodates an object to be packaged. It is fed to the top of the tray 19 that has been removed. Of the temporary sealing / trimming device 60, the first heat sealing plate 61, the trimming mechanism 65 for trimming, and the tension roller 68 are integrally moved for box motion. As shown in FIG. 1 and FIG. 2, if temporary sealing and trimming are performed on the bottom panel 14 in two columns and one row for each step while moving in a box motion, unlike the conventional high-speed model of a general tray packaging machine, Regardless of the tray conveyance frame pitch, it is possible to control the film feed corresponding to one row of trays, and the yield of the cover film 31 is improved.

As shown in FIG. 1, a carry-out conveyor 80 is disposed on the exit side of the small-diameter gear 12, and the tray 19 lifted by the support plate 29 in the pressure-resistant chamber 18 is moved to the synchronous supply device 50 shown in FIG. The tray 19 is transferred from the support plate 29 onto the carry-out conveyor 80 and carried out by a carry-out mechanism (not shown) such as the feeding device 51.

Next, the use state of the high-speed trace kinpack packaging machine of the present invention will be described. First, the tray 19 storing the objects to be packaged is aligned by the tray aligning device 40, the tray 19 is transferred to the bottom plate 14 of the pressure-resistant chamber 18 by the synchronous supply device 50, and the flange of the tray 19 is connected to the flange portion of the bottom plate 14. Set on 23. The timing for operating the alignment stopper 43 and the lift plate 71 of the tray aligning device 40, the speed of the string-like endless belt conveyor 41, and the feeding speed of the tray 19 by the synchronous supply device 50 are the same as the moving speed of the bottom plate 14 of the pressure resistant chamber 18. Control them together.

  In the temporary sealing / trimming device 60, as described above, the cover film 31 is temporarily sealed and trimmed depending on whether the package is raised from the upper surface of the tray 19 or not. The temperature of the first heat sealing board 61 when temporarily sealing the cover film to the flange is 100 ° C. to 180 ° C., preferably 120 ° C. to 130 ° C., and a sufficient temporary sealing effect can be obtained in about 1.0 seconds.

The tray 19 is provided with four air passages 34 in FIG. 5 that correspond to the unwelded welded portion 63 of the first heat seal board 61. The number and width of the air passages 34 vary depending on conditions such as the diameter and depth of the tray 19 and whether the packaged object is higher than the height of the tray 19 or lower than the height. For example, if the tray 19 has a diameter of about 20 cm and the package is less than the height of the tray 19, if there is at least one air passage 34 of about 10 mm, the air in the tray 19 is vacuum sucked to cover The film 31 can be skin-packed on the tray 19. However, a plurality of air passages 34 are preferably provided.

  As described above, the cover film 31 is temporarily sealed to the flange of the tray 19 and, at the same time, the cover film 31 is trimmed by the cutting blade 64 of the trimming mechanism 65. The temporary sealing and trimming are performed by the first heat sealing board 61, the trimming mechanism 65, and the like in a series of box motion operations in the temporary sealing / trimming apparatus 60.

As described above, the tray 19 that has been provisionally sealed and trimmed moves counterclockwise on the circular orbit around the large-diameter gear 11 while being placed on the bottom plate 14. And the said cover material 17 covers the said each base 14 in order. Air is sucked into the pressure-resistant chamber 18 by a vacuum pump, and the air in the tray 19 is sucked through the air passage 34 under the vacuum environment in the sealed region, and the inside of the tray 19 is the same as the sealed region in the pressure-resistant chamber 18. It becomes a vacuum environment.

However, since the air in the tray 19 is sucked through the air passage 34 having a high flow resistance, even if the pressure chamber 18 gradually becomes negative pressure, the inside of the tray 19 becomes negative pressure later than that. The cover film 31 expands into a dome shape due to the differential pressure between the pressure-resistant chamber 18 and the tray 19. In addition, the cover film 31 temporarily sealed from the lid member 17 side is sucked through the suction passage 26 and the cover film 31 is brought into contact with the second heat sealing plate 30 to be softened by heating, so that the inside of the tray 19 becomes a vacuum environment. At the stage, the second heat sealing board 30 welds the outer peripheral edge of the cover film 31 to the flange of the tray 19. At this time, the outer peripheral edge of the cover film 31 including the air passage 34 is completely welded to the flange and sealed so that the outside air does not enter the tray, and then the atmosphere is refluxed to the pressure resistant chamber 18 through the vacuum hose 33.

As described above, the inside of the tray 19 covered with the cover film 31 is in a vacuum environment, and the outside of the tray 19 is at atmospheric pressure. Therefore, when the atmosphere is returned to the pressure-resistant chamber 18 through the vacuum hose 33, the cover film 31 is wrapped. The skin pack packaging is completed by attaching to the surface. The tray 19 that has become a completed skin pack package is lifted from the bottom plate 14 by the support plate 29, transferred to the carry-out conveyor 80, carried out, and packed in a packaging box or the like after inspection.

In the above-described embodiment, the tray 19 storing the articles to be packaged is temporarily sealed and trimmed by the temporary sealing and trimming device 60 via the tray aligning device 40 and the synchronous supply device 50. In the present invention, since the tray 19 can be supplied by the long linear conveying portion of the bottom plate 14 of the pressure resistant chamber, the supply operation of the tray 19 is facilitated. Moreover, since the unloading work is also a straight line unloading, the unloading work becomes easy.

In the above-described embodiment, the tray 19 in which the objects to be packaged are supplied is supplied to the temporary sealing / trimming device 60 via the tray aligning device 40 and the synchronous supply device 50. In this section, the operator may place it directly on the bottom board 14, and the tray aligning device 40 and the synchronous supply device 50 are not essential components.

INDUSTRIAL APPLICABILITY The present invention can be applied to a high-speed tracekin pack packaging machine that continuously skin-packs objects to be packaged stored in a plastic tray.
