DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a food product in which confectionery such as chocolate, rice cracker, and bean confectionery are individually packaged, and a liquid food product such as jam, mayonnaise, soy sauce, and sauce.
The present invention relates to a method and an apparatus for collecting contents of food from food packaged in small portions for each usage amount.

[0002]

2. Description of the Related Art For example, rice crackers, chocolates, candy and other confections may absorb moisture, or may be melted by body temperature or the outside air. In many cases, paper is individually wrapped one by one. As one example of such a packaging, as shown in FIG.
Pillow wrapping or rectangular wrapping paper 8 that seals and wraps the vicinity of both ends of a cylindrical transparent wrapping paper 81 that wraps the wrapper 0 with air and forms a seal portion 82 by heat welding.
5, twist-wrapping is performed to wrap the candy 86 and twist both ends to prevent the candy from falling off. In addition, seasonings such as soy sauce and sauce are stored in a water-resistant plastic film bag in an amount necessary for a single use, and used together with food such as a lunch box.

[0003] In the inspection process before shipment, such packaged foods are caused by chipping or deformation of the packaged foods, insufficient or excessive quantity, abnormal packaging (eg, incomplete sealing, printing error), and the like. Defective or unsold goods occur. Since these defective products and unsold products are not derived from the quality of the contents of the contents, they can often be reused by collecting them. In such a case, in the past, in collecting these products, one end of the wrapping paper was cut by hand using scissors, and the contents were collected. ing. In addition, depending on the food to be collected, the cost required for collection is higher, so there is no waste that food that can be reused as food or for other purposes such as feed is discarded as it is. there were.

[0004]

SUMMARY OF THE INVENTION A first object of the present invention is to disclose an apparatus capable of easily separating various types of packaged food into contents and packages. A second object of the present invention is to disclose a method for easily and cleanly removing contents from various packaged foods.

[0005]

A first gist of the present invention is to provide a packaged food transportation path having a supply port for individually packaged food on one side and a discharge port for food separated from the wrapping paper on the other side. A part or all of which is a rolling gutter of packaged food constituted by one or more pairs of parallel rollers rotatable in opposite directions; a packaged food supply means for supplying the packaged food to one side of the rolling gutter; Roller rotation driving means for rotating each pair of rollers in a direction in which the pair of rollers is rotationally driven in the opposite direction to sandwich the wrapping paper of the packaged food between the pair of rollers and pull out the moving path. An apparatus for collecting food from packaged food.

As packaged foods, generation of dirt and food waste,
Jams, margarines, or mayonnaise, sauces, etc., in which confectionery such as rice crackers, candy, chocolate, etc. packed in a bag made of moisture-proof paper to prevent moisture, etc. The main target is seasonings such as soy sauce. In the supply port, hopper, vibrating gutter, conveyor, rotating brush, etc., providing supply means according to the properties of the packaged food,
It is desirable that the packaged food can be smoothly supplied to the rolling gutter.

[0007] The rolling gutter of the packaged food is constituted by one or more pairs of rollers extending in the moving direction of the packaged food, and an enclosing wall used as necessary. The diameter of the rollers constituting the roller pair is appropriately determined according to the size, shape, and properties of the packaged food. For example, if the roller diameter is too large compared to the size of the food to be separated, food may be bitten by the roller. If necessary, a rubber roller coated with rubber, a knurled roller, or the like may be used on the surface of the roller so that the roller does not slip when wrapping paper or the like is sandwiched. Of course, if there is a risk that the roller or the like may corrode due to the properties of the food, a surface treatment such as rubber, plastic, plating, or fluororesin coating is performed.

[0008] The packaged food is released outside the moving path by being drawn between the rollers. At that time, in order to prevent the food from being damaged, the packaged food packaged in an air-filled state is easily opened in a state where the air pressure is increased by the pinching action of the rollers and the bag is burst.
In the case of twist-wrapped candy and the like, the content food is extruded by a roller, so that the twist packaging is released and the content food is taken out. If the roller surface is coated with an elastic material such as rubber, it can be used for containers made of flexible materials such as plastic tubes and have different thicknesses.
Due to the elasticity of the roller itself, the container is squashed according to the change in the thickness of the container, and is easily passed therethrough. The roller pair is provided with a means for making the bearing portion of one roller an elongated hole and biasing it movably toward the other roller by a coil spring or the like, and a screw movable in the elongated hole toward the roller shaft. If means for adjusting the maximum allowable gap between the rollers, such as a stick, is provided, it is possible to cope with various types of packaged foods having different thicknesses of packaging materials.

The roller pair is provided on the side surface, bottom surface, ceiling surface, etc. of the rolling gutter according to the properties of the food. The roller pair may be exposed to a part of the gutter-shaped moving path (a part of the moving path may be formed of a roller pair), or the rolling gutter may be entirely formed of a roller pair. Good. In the case of a liquid food, a pair of rollers may be provided on a side surface or a ceiling surface, so that the food may flow on a bottom surface formed in a gutter shape of a plate material and reach a discharge port. The outlet may be lower than the supply port so that the food falls naturally by gravity.
As a rotation driving unit of the roller pair, a motor and an appropriate power transmission unit such as a gear, a chain, and a belt are used.

According to a second aspect of the present invention, in the food collecting apparatus defined by the first aspect, a packaged food agitating / transporting means comprising a spiral screw and its rotating means is provided along the inside of the rolling gutter. An apparatus for collecting food from packaged food, wherein the apparatus is provided.

[0011] Depending on the position and the number of the roller pairs, it may not be easy for the packaged food that has entered the rolling gutter to reach the roller pairs. Further, depending on the nature of the food, there is a case where it is desired to discharge and collect the taken out food as soon as possible. The spiral screw stirs the packaged food up and down in the rolling gutter and plays a role of moving the taken out food to the discharge port side. As a spiral screw, a spirally bent bar or a ribbon screw provided with a spiral ribbon around the central axis, brush bristles radially implanted on the surface of the rotating shaft so as to form a spiral And the like.

A third aspect of the present invention is that one or more pairs of parallel rollers rotatable in opposite directions constitute a part or all of a packaged food moving path, and the packaged food supplied to the moving path moves. There is a method of collecting food from packaged food by moving a food packaging material between a pair of parallel rollers and pulling the food packaging material out of the travel path when moving along a path.

In the case of a liquid food, it is desirable that the position of the roller pair is provided on the ceiling or the side, and the collected food flows down a gutter provided on the top surface. In that case, the packaging material is discharged to the upper part and the side of the rolling gutter.

[0014] A fourth aspect of the present invention is a food collection method defined by the third aspect, wherein the packaged food is prepared by:
A method for recovering food from packaged food is characterized in that the packaged food is moved while moving the packaged food in the vertical direction by agitating and transferring means provided along the moving path.

[0015]

1 to 3 show one embodiment of a food collecting apparatus according to the present invention. In FIG.
The food collection device 1 of the present application has 5
A rolling gutter 3 is formed in which a pair of parallel roller pairs 2a to 2e are arranged in parallel to form a gutter shape close to each other. Roller pairs 2a-
e are provided with bearing portions 4a and 4b. The bearing 4a on one side is a bearing plate having a U-shaped profile, and each roller 2a
a-side roller shaft 5a protruding in the axial direction at both ends of a to e
To e are rotatably supported via rolling bearings (not shown). A roller shaft projecting to the other side of the roller pair is similarly rotatably supported by a U-shaped bearing portion 4b.

The roller pair (2a, 2a), (2b, 2
Each of b),..., (2e, 2e) is formed by forming a roller shaft of a smaller diameter at both ends of a metal round bar,
Knurling is applied to the surface of each roller so that the wrapping paper is sandwiched without slipping. The pair of rollers are provided with a very small gap therebetween so that the wrapping paper can be sandwiched and pulled out from the moving path. Therefore, it is necessary to change the interval depending on the packaged food in which the thickness and the degree of flexibility of the wrapping paper are extremely changed. In this case, one of the roller shafts may be supported so as to be able to move slightly, but an elastic roller having an elastic layer made of a rubber elastic material or the like formed uniformly on the roller surface may be used.

The bearings 4a and 4b are fixed at predetermined intervals by fixed frames 6, 6 provided between the side surfaces of both bearings. As shown in FIG. 2, each of the roller shafts 5a to 5e on the bearing portion 4a side penetrates through the bearing portion 4a and protrudes to the other side of the bearing portion. (10 in the figure)
A series of gear trains is formed by being fixed so as to rotate integrally with a to e and meshing with each other.

A drive gear 21 directly connected to the output shaft of the geared motor M meshes with an arbitrary gear (7b) forming a gear train. An arbitrary gear (7b) forming a gear train meshes with a pinion 17 rotatably supported by a bearing 4a, which rotates near the center of the bearing 4a in parallel with the rollers. The gear 8b meshes with a freely supported rotating shaft 8a and a gear 8b that rotates integrally. Thus, in FIG. 2, when the drive gear rotates clockwise, five pairs of gears (7a, 7a), (7b, b), (7) mesh with each other.
(c, 7c), (7d, 7d), (7e, 7e) rotate in opposite directions. Therefore, as shown in FIG. 3, five pairs of rollers (2a, 2a) to rotate integrally with these gear trains.
(2e, 2e) also rotate in the direction opposite to each other in the direction of the arrow.

A rotating shaft 8a to which the gear 8b is fixed protrudes from the other side of the bearing portion 4a, and a protruding end 8c has a spiral screw 8 formed by spirally bending a rod material.
Is screw-fixed and supported at the rotation center (center axis). The spiral screw is
It is preferable that a spiral brush or the like in which brush hairs are planted in a spiral shape on the central axis be detachable and replaceable as necessary according to the properties of the packaged food. The tip 8d of the spiral screw 8 extends to a discharge port 9 opening to the bearing 4b on the other side of the rolling gutter 3. A chute 9 a for dropping the collected food is provided facing the outlet 9.

The upper surface of the rolling gutter 3 is covered with a detachable top plate 12, and the packaged food is dropped and supplied to a supply port 10 opened at a position adjacent to the bearing portion 4a of the top plate 12. One end of the vibrating gutter 13 is provided as a supply means for the above. A lower portion of a hopper 14 is connected to the other end of the vibrating gutter 13, and a rotating brush 15 for supplying packaged food to the vibrating gutter 13 on average is provided below the hopper.

[0021]

A method of recovering contents from packaged food using the above-described apparatus 1 will be described. As shown in FIG. 5, a candy 86 having a twist package is put into the hopper 14 of the apparatus 1 and the motor M is turned on. When the motor M is turned on, each roller pair rotates in the opposite direction, and the spiral screw 8 , Rotating in a direction to transfer the candy in the rolling gutter 3 to the discharge port side. The candy 86 is dropped and supplied from the supply port 10 into the rolling gutter via the brush 15 and the vibration gutter 13 at an appropriate pitch. The candy that has entered the rolling gutter 3 is stirred up and down by the spiral screw 8, and is supplied to the supply port 1.
It is conveyed slowly from the 0 side to the discharge port 9 side. At this time, the end 85a of the wrapping paper 85 of the candy 86 is
As shown in (2), the wrapping paper end portion 85a is caught and caught between any of the roller pairs 2, 2, and is drawn in so as to be discharged to the outside of the rolling gutter 3.

As a result, the candy 86 is
Pressed by 2 to untwist the twist wrap,
It is pushed out from 5. In the case of a pillow package in which the chocolate 80 or the like as shown in FIG. 6 is sealed together with air, when the seal portion 82 is sandwiched between the pair of rollers 2, 2, the bag of the wrapping paper 81 is ruptured by the pressure of the roller, and the chocolate 80 Is easily pushed out of the bag. The confectionery detached from the wrapping paper is sent to the outlet by the spiral screw 8 and enters the collection box 30 from the dropping chute 9a. The wrapping paper falls into a box 31 placed under the rolling gutter 3.

In the above embodiment, the roller pair is driven by a gear train, but any known means such as a chain drive can be employed. Also, the side and bottom of the rolling gutter,
Although only the roller pair is used, this may be a case where the roller pair is provided in a part of the rolling gutter. For example, when the food to be collected is a fluid, a pair of rollers may be provided on the side surface or the ceiling surface, and a flow gutter for collecting the food may be provided on the bottom surface. In this case, the adherence of the liquid food to the roller can be reduced.

[0024]

According to the apparatus and the method of the present invention, the conventional manual collection of food can be easily and quickly performed.
It can be carried out efficiently, the chances of adhesion of various germs are small, and the food can be reused without being wasted.
