Description

[Detailed Description of the Invention] The present invention relates to an apparatus for automatically packaging, for example, margarine, butter, etc., in a plate-shaped food product having surface adhesive strength, using an upper sheet and a lower sheet I in a sand switch shape.

Conventionally, according to a packaging device for plate-shaped foods such as marcarin or butter that has surface adhesive strength, a plate-shaped food a is folded and packaged from above and below into a U-shape as shown in Figures 1 and 2. In some cases, the cut ends of the upper sheet part and the lower sheet part C are uneven and have an uneven shape.

Furthermore, if you sharpen the cutting blade and cut the upper sheet part, the lower sheet part C
Even if the plate-shaped food product a was cut into a straight line, the edges d and e of each plate were shifted, resulting in a disadvantage that part of the plate-shaped food product a was exposed as shown in Figure 3.

In the conventional packaging device, it is necessary to further provide a plurality of position detection devices for the plate-shaped food and a plurality of length detection devices for the packaging sheet 1, and a mechanism for synchronizing the conveyance position of the plate-shaped food and the position of the cutting edge of the packaging sheet. It also had the disadvantage of complicating things.

Furthermore, since the packaging sheet needs to be fed out intermittently, it is necessary to attach an electromagnetic brake and a clutch to the power source of the packaging sheet feeding device, which has the disadvantage of further complicating the structure.

The present invention eliminates all of these conventional drawbacks, and allows packaging of plate-shaped foods with surface adhesive properties such as margarine and butter by completely covering the upper and lower surfaces with the upper packaging sheet and the lower packaging sheet I, respectively. At the same time, the purpose of this invention is to provide a packaging device that can cut the upper and lower sheets accurately and beautifully and smoothly, has a simple structure, is inexpensive, and is less likely to break down. a distance increasing mechanism for increasing the distance between successively delivered plate-shaped foods having surface adhesive force to a predetermined value by setting the traveling speed of a downstream conveying device higher than the speed; a sensing mechanism that senses that the plate-shaped food placed on the belt-shaped lower packaging sheet that is continuously sent out by the downstream conveyance device to be placed thereon has been conveyed to a predetermined position by the downstream conveyance device; At a position further downstream from the sensing mechanism,
An upper packaging sheet that is continuously sent out so as not to adhere to the upper surface of the plate-shaped food is elastically pressed onto the upper surface of the plate-shaped food so as to adhere using the surface adhesive force of the plate-shaped food; and a resilient pressing mechanism that resiliently presses the upper sheet to bring it close to or in contact with the lower sheet in the gap having the above-mentioned interval dimension; and a cutting mechanism actuated by the sensing mechanism to cut both the lower sheet and the lower sheet.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

In FIGS. 4 and 5, 1 is a long plate-shaped food product such as margarine or butter with surface adhesive strength, which is extruded from an extrusion device (not shown) and transferred to an upstream conveyance device 3 such as an endless belt conveyor 2. It is sent in the direction of arrow B at a predetermined traveling speed.

Therefore, 4 is a long plate-shaped food 1, a rectangular plate-shaped food 5...
It is a fixed-size cutting device that continuously cuts into... More specifically, the fixed-size cutting device 4 is supported on a machine stand 6 having an upstream conveying device 3, and endlessly cuts in a downstream inclined manner. A shaped chain body 7 is moved in the direction of arrow C by integral wheels 8 and 9, and cutting blades 10 are provided at predetermined intervals on the chain body 7.
... are provided protrudingly, and one wheel 8 is rotated in the direction of arrow C by a transmission mechanism such as a belt 11 via a motor and a transmission (not shown) installed in the machine base 6. Ru.

The sizing cutting device 4 is supported by supports 12.13 attached to both sides of the machine base 6, and the downstream wheel 8
is made large in diameter, the upstream wheel 9 is made small in diameter, and is arranged in a downstream inclined manner, and a height adjustment member 10 such as a turnbuckle is interposed in the support 13 so that the inclination angle can be adjusted in size. -The cutting blade 10 cuts downward as it goes downstream, as shown in the figure, while adapting to the thickness of the long plate-shaped food 1 transported in the direction of arrow B by the upstream transport device 3. It is configured to completely cut the rectangular food 5.

Note that the cutting blade 10 is set at an angle so as to cut into the long plate-shaped food 1 perpendicularly, and cuts the food 1 downstream while cutting.
The cutting blade 10 reaches the belt conveyor 2 at the final position, that is, directly below the center of the large-diameter wheel 8, and
The food 1 is completely cut.

Note that 15 is a heating device that can be attached as desired, and is used to heat and melt deposits that adhere to the cutting blade 10 after cutting the food 1 such as margarine to a certain size.

Further, 16 is an integrated cover, which protects the sizing cutting device 4.
It prevents the heat from the heating device 15 from escaping and also serves to completely protect the body.

However, the sizing cutting device 4 is not limited to the above specific example,
It is also possible to form the rectangular food product 5 by cutting it into a fixed size using a cutting blade that repeats only vertical movements.

In this way, the rectangular foodstuffs 5 are cut into predetermined lengths, and the rectangular foodstuffs 5...
... are sequentially sent by the upstream conveyance device 3, and the food products 5... are sequentially transferred to the adjacent downstream conveyance device 18 such as the bell I conveyor 17, It is transported in the direction of the arrow.

However, the traveling speed of the downstream conveying device 18 is set higher than the traveling speed of the upstream conveying device 3, and the plate-shaped foods 5...
A distance increasing mechanism 19 is configured to increase the mutual distance A of the... to a predetermined value.

The predetermined value of this interval dimension A is set in advance so that the sensing mechanism 20 (described later) operates reliably and accurately, and the resilient pressing mechanism 21 operates reliably, and the magnitude of the predetermined value is The adjustment is performed by the downstream conveying device 1 with respect to the upstream conveying device 3.
This is done by adjusting the magnitude of the traveling speed difference in step 8.

Next, the downstream conveyance device 18 includes the belt conveyor 17.
Another bell I, located adjacent to the
A conveyor 22 is attached to a machine base 23-H, and on the upper surface of the belt conveyor 22 on the downstream side, a wrapping sheet I/24 such as wrapping paper or a fat sheet is deposited sequentially in the direction of the arrow E. It is sent out continuously.

30 is a feeding device for this lower packaging sheet 24;
The device 30 is attached to the machine base 23 and is attached to one horizontal support shaft 25.
, 25, the packaging lower sheet 24 is sent out from either one of the lower sheet rolls 26.
The plate-shaped foods 5 are placed on the lower sheet 24 on the belt conveyor 22 with the predetermined interval dimension A as they are. and is continuously sent in the direction of arrow E.

Although Figures 4 and 5 are shown in separate drawings due to the size of the drawings, they are actually continuous devices, and as shown in Figure 5, the machine 23 includes a sensing mechanism 2
A phototube, an air sensor, and other proximity switches are used to move the rectangular plate-shaped food 15 placed on the upper surface of the lower packaging sheet 24 to a predetermined position using the downstream conveyance device 18.
The sensing mechanism detects that one piece has been transported by
It senses individuals.

Next, at a position further downstream of the sensing mechanism 20, preferably at a position as close as possible to the sensing mechanism 20, the top sheet 29 applied to the top surface 28 of the rectangular plate-shaped food 5 is continuously placed. , are sent out by the upper sending device 31.

Specifically, a support 32.
32, a mounting base 33 with a feeding device 31 is provided, and a pair of horizontal support shafts 25.25 support the upper sheet 29.
Wound upper sheet rolls 34 and 34 are rotatably mounted on an axis, and the upper sheet 29 is continuously fed out from one of the upper sheet rolls 34 to the elastic pressing mechanism 21 by a group of rollers 35. However, a feeding speed adjusting member 36 for the upper sheet 29 is interposed between the groups of rollers 35, and swings in the directions of arrows G and H to adjust the storage length of the upper sheet 29 between the groups of rollers 35. By changing the
The feeding speed of the upper seams 1 to 29 at the position of the elastic pressing mechanism 21 is adjusted.

37 is a member that uses a spring, a damper, etc., and controls the swinging of the adjustment member 36.

Although the material of the upper sheet 29 is the same as that of the lower sheet 24 described above, the upper sheet 29 fed out by the feeding device 31 in this way is made by utilizing the surface adhesive force of the rectangular plate-shaped food 5. Then, the upper sheet 29 is pushed elastically downward by the spring 38 or an air compression force (not shown), and the upper sheet 29 is brought close to the lower sheet I/24 in the gap 39 between the foods 5, 5 having the interval dimension A. The resilient pressing mechanism 21 performs the action of resiliently pressing downward to come into contact with the sensing mechanism 20. In a specific example, the swinging arm 40 disposed downstream and near the sensing mechanism 20, It extends from a pressing rotor 41 etc. which is rotatably attached to the tip of this swinging arm 40, and is elastically biased in the counterclockwise direction in FIG. 5 by the spring 38 and air compression force. .

Next, 42 is a cutting mechanism that cuts both the upper sheet 29 and the lower sheet 24 that are close to each other or in contact with each other in the gap 39, and in the specific example, the upper and lower sheets) 29.2
4)) also has a band-shaped cutting blade with a large width, and simultaneously cuts the upper and lower seams in the adjacent gaps 39 and 39.
A pair of cutting blades 43 are provided upstream and downstream to cut 9.24, and are simultaneously operated in the direction of arrow J by a drive mechanism (not shown).

The operation of this cutting mechanism 42 is controlled by the sensing mechanism 20.
It is controlled by

In other words, it is automatically known from the traveling speed of the belt conveyor 22 in the direction of arrow E and the distance from the sensing mechanism 20 to the cutting blade 43 that the center of the gap 39 is directly below the cutting blade 43. Such automatic control can be easily performed by electrical means or the like.

The belt conveyor 22 extends up to the cutting blade 43, and a conveying device 45 such as another belt conveyor 44 which is at the same speed or a slightly higher speed is disposed downstream. is up to the position of the cutting blade 43 on the downstream side, and a conveying device 47 such as another belt conveyor 46 at the same speed is disposed at the downstream position, and at the time of cutting,
The height position of the lower sheet 24, that is, the belt conveyor 22,
44. Arrow J below the height position of the top surface of 46
The F-sheet 24 is struck horizontally so as to completely and reliably cut the F-sheet 24.

Here, it may be run at the same speed as the bell 1 to the conveyor 44.46 (44.46 degrees) and the conveyor 22, but by setting it at a slightly higher speed, the lower sheet 24 will bend downward at the cutting blade 43 position during cutting. This is preferable because it prevents this from occurring, makes cutting easier, and makes the cut surface beautiful and linear.

A delivery mechanism 48 is provided downstream of the transport device 47 for transporting the food 5 sandwiched between the upper sheet 29 and the lower sheet 24 to the next step.

In the specific example, a bell) conveyor 22 arranged in a row,
44.46, there are rollers 50.50 that roll guided by rails 49.49, and the food 5
A cylinder 53 is used to actuate a delivery table 52 having springs 51 and 51 to reduce the shock when the bell falls, but this is not possible by using a separate bell 1 to conveyor or by using an inclined plate. Be free.

Although the cutting blades 43 are a pair in the above specific example, the number can of course be increased or decreased, and may be one, three or more.

In addition, the machine base 6゜23 is equipped with running wheels 5 for easy transportation.
It is preferable to attach 4.......

Reference numeral 55 is a fixed leg fixed to the floor, which also functions to adjust the height of the machine bases 6 and 23.

The present invention is constructed as described above, and its operation will be explained in more detail as shown in FIGS. 6, 7, and 8.
If the long plate-shaped non-defective products 1 are still cut by the various sizing cutting devices 4, the mutual spacing between the rectangular plate-shaped foods 5 is too small, and as shown in FIG. They are fed side by side by the upstream conveying device 3, but then, as shown in FIG. The dimension A is increased to a predetermined value 7 and sent.

Next, as shown in FIG. The sensing mechanism 20 such as an air sensor or the like can reliably detect one object without malfunction.

Next, as shown in ■■ in the same figure, if the upper sheet 29 is elastically pressed onto the top surface of the plate-shaped food 5 by the elastic pressing mechanism 21, the surface adhesive force of margarine etc. is increased. Because of this, the upper sheet 29 is adhered to the upper surface of the plate-shaped food product 5.

Further, as shown in FIG. V, the upper sheet 29 is deflected so as to come close to or come into contact with the lower sheet 24 by the elastic pressing mechanism 21.

Therefore, in the next step, as shown in v1 of the same figure, the above-mentioned sensing mechanism 2
0 l) The operating cutting mechanism 42 cuts the top sheet 29.
When cutting the lower seam 1-24 and the lower seam 1-24 at the same time, it is possible to cut straight and smoothly at an accurate position, that is, at the center of the gap 39.

However, as shown in Figure 7 IJr, the upper sheet 29
When the lower sheet 24 is not in close proximity to the lower sheet 24 and the elastic pressing mechanism 21 is not used, when the cutting blade 43 is pushed down in the direction of the arrow J, only the upper sheet 29 has its tip end aligned with the arrow M.
It can be seen that since the food product 5 easily moves in the direction, a problem arises in which a part 56 of the food product 5 is exposed as shown in FIG. 7II.

In addition, because the cutting positions of the upper sheet 29 and the cutting blade 43 slip and deviate from each other, the strip-shaped upper sheet 29 may not be cut perpendicularly to the longitudinal direction but may be cut obliquely, or if it is extremely severe, the cutting position may be cut in an uneven manner. be cut or torn.

Therefore, in the first aspect of the present invention, in order to make full use of the property of having surface adhesive force, the upper sheet 29 is pressed downward by the resilient pressing mechanism 21, and the upper sheet 29 is
Since the upper sheet 29 is adhered to the upper sheet 29 and then cut by the cutting blade 43, it is possible to completely prevent the upper sheet 29 from shifting in the direction of the arrow M in FIG.

Further, since the upper sheet 1-29 and the lower sheet 24 are cut close to or in contact with each other in the gap 39 and then cut by the cutting blade 43, this is more effective in preventing the above-mentioned misalignment, and It can be cut at a position that coincides with sea 1-29.24.

In this way, a rectangular plate-shaped food product 5 is obtained in which the cut upper sheets 1 to 29 and the lower sheet 24 are bonded together in a sandwich-like manner, as shown in FIG. 6 (11).

As shown in Fig. 6 (111), even if sandwich-like foods 5 are stacked up and down in multiple tiers, they will not stick to each other; for example, in the case of margarine, during the production of Western confectionery. In addition, by counting the number of foods 5 that have been molded to a predetermined weight as 1... Not only can it be made more efficient, it is also sanitary, and there is no need to use a measuring device or a scraper such as a rice scoop.

In addition, the packaging sheets 29 and 24 have no directionality and can be removed from any of the four sides of the rectangular plate-shaped food 5, allowing for quick sheet removal work.

FIG. 8 shows a plan view of the food 5 made into a sandwich shape as described above, whereas the conventional FIGS.
Comparing Figure 3 with Figure 3, it is clear that
The food 5 is adhered precisely to the center of the sheet 29.24, and the four sides of the sheet 29.24 are straight and smooth.

The present invention is constructed as detailed above, eliminates all the conventional drawbacks, and effectively achieves the intended purpose.
It can be said to be an excellent packaging device that makes extremely effective use of the surface adhesive strength of marnigarin, butter, etc.

In particular, the interval dimension increasing mechanism 19 has a simple structure in which the running speed of the downstream conveying device 18 is set higher than that of the second-stream conveying device 3, and prevents malfunction of the sensing mechanism 20.
This has the effect of making it easier to approach or abut the lower sheet 24 of the sheet 9 .

Furthermore, since the rectangular plate-shaped food 5 is placed on the lower sheet 24 first and then the upper sheet 29 is placed on it,
Malfunctions of the sensing mechanism 20 can be more reliably prevented, and
This makes it difficult for the lower sheet 24 to have wrinkles, creases, or other imperfections.

Furthermore, since the second sheet 29 and the lower sheet 24 are each fed out independently, they can be fed out together continuously, and there is no intermittent movement as in the conventional case, so the driving source is an electromagnetic brake or clutch, etc. becomes completely unnecessary,
Quiet operation was achieved.

In addition, as described above, the elastic pressing mechanism 21 prevents the upper sheet 29 from shifting relative to the food 5, so that the food 5 can be sandwiched between the upper and lower sheets 29 and 24 precisely at the center position. As well as upper and lower seats 29.24
The cut edge will be straight and smooth.

Furthermore, as described above, the cutting mechanism 42 is operated by the sensing mechanism 20, which operates accurately without malfunction, and the upper and lower sheets 29, 24 are cut while being close to each other or in contact with each other.
The cutting position becomes more accurate, and the food 5 is sandwiched in the center of the upper and lower seams 1-29, 24.

As described above, it can be said that the practical effects of the present invention are significant as a packaging device for plate-shaped foods having surface adhesiveness such as margarine.
