Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separating device for separating a packaging member from contents, and more particularly to a separating device used for disposing of packed food sold in a supermarket or the like.

[0002]

[Prior Art and Problems] Conventionally, in food sales in supermarkets, etc., food is placed on a plate or tray made of foam material and covered with a transparent resin sheet because of its easiness of packaging, handling and confirmation of contents. ing. So-called packed food. Then, a sticker on which various legally designated indications are written is attached, and the product is appropriately stored in a display case, a refrigerating case, or the like for sale. On the label of the sticker, the shelf life and shelf life of the food that consumers particularly care about are also described, and many consumers confirm this description before purchasing.

However, not all manufactured packaged foods are sold within the expiration date or expiration date indicated on the sticker, and some unsold products are left unsold. The unsold items are later sorted into packaging materials and the foods they contain and discarded as appropriate.However, when there are many packed foods to be discarded, sorting the packaging materials and the foods is troublesome and time consuming. It was also difficult because it took too long. Therefore, the device disclosed in Japanese Patent Laid-Open No. 11-333315 was devised, and it became possible to automatically separate the packaging material and the food product.

However, this device is provided with an input port on the side of the device for inputting the packed food to be discarded into the device, and the input port is provided with an appropriate inclination upward. Since a slide-in loading path is provided,
The total length of the device is a length including the separation part for the packed food and the carry-in part for loading the packed food, which is the main body of the device, and there is a drawback that the installation requires a large area. And, since the protruding length of the protruding member for hooking the packaging material for the packed food provided adjacent to the input port is short, the packaging material is flipped without being caught, or the packed food is obliquely from above. Since the food comes in, the packed food may pass through without coming into contact with the protruding member, and the packaging material may enter the separation drum without being broken.

[0005]

[Object] The present invention has been made in view of the above-mentioned problems, and can reliably cut a package of a packed food product (object to be processed) that has been put therein, and can compact the device without sacrificing the processing capacity. An object of the present invention is to provide a separation device that can be used.

[0006]

SUMMARY OF THE INVENTION The gist of the present invention is that a rotatable shaft forming vanes is provided in a curved case having a plurality of holes at least in a lower portion thereof.
The rotation direction is the same as the bending direction of the case, and at least a part of the blade is positioned laterally inside the curve, and one end of the blade is provided with a breaking member that projects substantially parallel to the axis. The separation device is characterized in that an input port for the object to be treated is provided vertically above the breaking member of the case, and a discharge port for the residue is provided in the case on the side opposite to the input port.

The separation device of the present invention will be described in more detail. The case of the present device has a hole for discharging the contents (food or the like) discharged from the packaging member cut by the breaking member described later to the outside of the case. Are drilled. The hole is
It may be provided anywhere on the case as long as it is suitable for discharging, but specifically, it may be provided on the curved portion of the case. The number and arrangement form of holes, the shape and size, etc. are not limited. For example, the number and arrangement form of holes may be changed on the left and right sides of the case, or the shape of holes may be changed depending on the row and position. (Circle / oval / tear / triangle / rhombus / polygon / quadrangle, etc.) and size may be changed. A container body for receiving discharged matter may be provided below the case (hole).

Further, the lower portion of the case is curved, and the curvature of the curvature is preferably set to be approximately the same as or slightly larger than the curvature of the rotation locus of the blade described later. This is because the processing efficiency is better when the blades are provided closer to the case. The curve means that not only all of the curved parts are formed by curved lines, but also a large number of straight lines are continuously arranged, or a straight line and a curved line are appropriately connected to form an apparent curve. It may be one. However, when forming a curve by connecting straight lines, it is better to reduce the variation in the gap between the blade and the case.

The shape of the other parts except the curved portion of the case is not particularly limited, and may be any shape as long as it can accommodate each member constituting the device.
As a specific example of the overall shape of the case, it may have a circular cross section, a U-shaped cross section with an upper part closed, or an oval cross section, and a horizontally extending cylindrical shape with both ends closed.
Further, an outer case having an appropriate shape may be formed on the outside of all or part of the case having the above shape. That is, the whole or a part of the case may have a multi-layered structure so that the separated and discharged substances cannot be seen from the outside.

In the case, a shaft around which blades are formed is provided so that its rotation direction is the same as the bending direction of the case. The shaft and blades should be suitably long in the axial direction. The blades stir the packaging member in order to take out the contents from the cut packaging member, and also stir the contents in order to break the contents coming out of the packaging member. The number and shape of the blades are not particularly limited. As a specific form, it is preferable that the blade has one blade and the blade has a spiral shape around the axis, and the blade has a plurality of blades. It is preferable to install the vanes in the centrifugal direction about the axis. The centrifugally-provided blades may also have a flat plate shape, or may have a curved plate shape with appropriate twist.

The shaft may be installed so that the blade is rotatable with a proper gap between the blade and the case. However, as described in the description of the case, it is more efficient to dispose the blade close to the case. As it is excellent, the shaft installation must also take this into account. Further, a breaking member is laterally provided in a protruding shape from one end of the blade in the axial direction. This breaking member is for breaking the packaging member of the object to be treated (packed food etc.) put in the case, and an appropriate portion of the blade, for example,
It is attached to the front and rear faces and end faces in the direction of rotation. The breaking member may be projected in parallel with the axis, but may be projected with an appropriate angle (vertical / horizontal). It can be said that these are almost parallel. Further, one blade may be provided for one blade, but of course, a plurality of blades may be provided for each blade, and further, cutting blades having different shapes may be provided. It may be provided every few blades. The radius of rotation may be different by changing the distance from the shaft.

[0012] The attachment may be performed by a fixable member, but it may be formed integrally with the blade. The breaking member may be any member as long as it can cut the packaging member. Specifically, it may be formed of a round bar, a square bar (triangular / polygonal), a plate-shaped metal, a resin, wood, or the like. Good. Further, one or more blade members can be fixedly or detachably attached to an appropriate portion of the breaking member,
You may make it cut | disconnect a packaging member with this blade material.
When a plurality of blade materials are provided, the types and shapes of the blade materials may be unified, or different blade materials may be provided.
Furthermore, one or a plurality of protrusions or protrusions may be formed at an appropriate portion of the breaking member. It is desirable that the breaking member has a length substantially the same as or longer than the axial opening length of a charging port for charging a workpiece to be described later.

The shaft must rotate so that the breaking member can cut the packaging member. A motor is often used as a drive source for rotation, and the installation site of the motor in the device is not particularly limited, but in consideration of downsizing of the device, it is installed above the case, and rotation transmission of belts and gears is performed. The rotation may be transmitted to the shaft via means. Of course,
The rotation speed may be adjustable. Then, the breaking means cutting the packaging member into a plurality of pieces, breaking the packaging member, or making a cut in a part of the packaging member, and making the contents come out of the packaging member.

The case above the breaking member is provided with a charging port for charging an object to be processed. That is,
A breaking member is provided at a drop point of the object to be processed, which is charged from the charging port. The shape of the charging port, the size of the opening, and the like may be determined in consideration of the dimensions of the breaking member described above and the shape or the size of the opening that allows the charged object to contact the breaking member. Also, a suitable lid may be provided at the inlet. Then, a transport path or a transport means for transporting the object to be processed may be provided at the input port.

A discharge port for discharging the residue (packaging member) is provided in the case opposite to the input port in the axial direction. The installation site of the discharge port is also not particularly limited, but it is preferably provided on the side of the blade above the shaft. The shape and installation form of the discharge port are not particularly limited, but the residue may be protruded outside the side surface of the case so that it can be retained near the discharge port, or may be provided adjacent to the rear of the blade in the case. Good. Further, a suitable container for receiving the residue may be provided at or near the discharge port, and further, a suitable lid may be provided at the discharge port.

A guide means for guiding the residue to the discharge port is provided at an appropriate portion of the device. The guide means is
Any form may be used as long as the residue can be guided to the discharge port side.For example, a fin-shaped member for guiding the airflow generated by the rotation of the blades toward the discharge port is attached, The flow of the airflow guides the residue from the inlet to the outlet. Specifically, a wind direction changing member for changing the direction of the wind generated by the rotation of the blades toward the discharge port is provided in the upper part of the case, that is, the top, etc. The means may be provided in the case, or the blade may be provided with a wind direction changing member to change the direction of the wind toward the discharge port.

[0017]

Since the separating apparatus of the present invention is constructed as described above, the apparatus is first activated when processing packed foods such as those whose expiration date has expired. That is, the motor for driving the rotating shaft is activated. When the motor is started, the rotation of the motor is appropriately transmitted to the rotating shaft by the transmitting means, and the blade and the breaking member start to rotate together with the shaft. Then, the packed food that is the object to be processed is sequentially charged into the case from the charging port.

The packed food put into the case falls vertically from the charging port, and the breaking member rotates in the passage space, so the packed food hits the breaking member and the packaging is broken by the breaking member. The food, which is the content, is ready to be discharged from the packaging member. Then, the packed food is stirred by the rotation of the blades, and the packaging member and the food are separated. The separated food is further agitated by the rotation of the blade, thereby being crushed into fine particles by hitting the inner wall of the case, the blade and the like, and discharged from the many holes of the case to the outside of the case. Further, the container provided with the container is housed therein.

The separated packaging member flies in the case by the rotation of the blades, is guided to the discharge port side by the rotation of the blades, and stays near the discharge port. In the case where the guide means for guiding the packaging member to the discharge port side is provided, the packaging member is guided to the discharge port side by the guide means and stays near the discharge port as the blade rotates. Further, the container provided with the container is housed therein.
