Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can crushing device for compressing and reducing the volume of used empty cans one by one in order to promote the efficiency of resource reuse and environmental protection, and particularly to improve safety and An empty can crushing device having high maintainability.

[0002]

2. Description of the Related Art Conventionally, various empty can processing devices have been developed and put into practical use as a device for crushing empty cans of beer and soft drinks. In the empty can crushing device in which the movable pressing body and the fixed plate cooperate to crush (press) the empty can, the empty can is provided with a safety measure so that the hands cannot be inserted into the compression chamber of the device from the charging port. A crushing device is required. As a device related to this type, for example,
There is Japanese Patent Application No. 6-51597 filed by the same applicant as the present invention. The device disclosed in Japanese Patent Application No. 6-51597 includes a compression chamber that crushes an empty can with a fixed plate and a movable pressing plate, and an opening for inserting and removing the empty can into the compression chamber. A door plate is pivotally attached to the opening so as to be openable and closable, and the door plate is formed by integrating the door part and the empty can stand part at each one end into an L-shape. When the door plate is opened, the empty can stand that is integrated with the door plate protrudes into the operation space of the movable pressing plate and acts as a stopper that prevents the movable pressing plate from moving, and when the door is closed (empty can compression process). The middle) is configured such that the movable pressing plate that has moved forward locks the empty can stand table and prevents the opening of the door plate.

[0003]

In the above-mentioned prior art, the risk of fingers, hands, etc. being caught during the compression operation of the device is eliminated, and the empty can is stuck in the path part in the device, causing the device to malfunction. There is nothing to do. However, there is a problem that the empty can is deformed by the compression and the upper lid part having the mouth is broken and a burr is generated, and when the empty can with the burr is taken out, the burr causes a cut on a finger, a hand or the like. . Also,
By compression, the pull-top attached to the mouth of the empty can is separated from the empty can, and the joint between the fixed plate and the empty can stand, the gap between the movable pressing plate and the empty can stand, and the movable pressing plate There is a problem that the detached pull-top is caught in a gap in the compression chamber, such as a gap between the compression chamber and the ceiling plate of the compression chamber, which impedes the compression operation of the movable pressing plate. In addition to the detached pull-top, there is a problem that the upper and lower lids and the bottom of the empty can are caught in the clearance inside the compression chamber due to the deformation of the empty can due to the compression. Therefore, an object of the present invention is to provide an empty can crushing device provided with a compression chamber for crushing an empty can with a fixed plate and a movable pressing plate, without causing burr in the crushed empty can, and by compressing the empty can. It is to realize a device that can reduce the volume and recover the empty can with the simplest structure possible without the pull-top separated from the device getting caught in the gap in the compression chamber.

[0004]

In order to achieve the above object, the present invention provides a compression chamber (FIG. 1) for crushing an empty can with a fixed plate (10 in FIG. 1) and a movable pressing plate (6 in FIG. 1). 20), the lower part of the fixed plate on the compression surface side is provided with a first inclined surface where the thickness of the fixed plate gradually increases toward the lowest part of the fixed plate, and the movable pressing member is provided. A central portion of the plate on the compression surface side has groove portions formed in a straight line in the vertical direction, and is formed on both left and right sides of the groove portion so that the thickness gradually increases from the central portion toward the left and right sides of the compression surface. The second inclined surface is provided (see FIG. 3). Also,
A compression chamber that crushes the empty can with a fixed plate and a movable pressing plate is provided.
In empty cans crushing device for crushing empty cans placed face up spout, the ceiling part and the floor part of the compression chamber is provided parallel to the plurality of grooves and the traveling direction of the movable pressing plate, and, Concavo-convex portions are provided on the upper and lower portions of the movable pressing plate so as to mesh with the plurality of grooves (see FIG. 5). Also,
A step is provided at the joint between the fixing plate and the empty can stand, which is the deepest bottom of the compression chamber, and a pull-top discharge port that is separated from the crushed empty can is provided (see FIG. 6).
In addition, the inclined surface of the fixed plate and the lower portion of the movable pressing plate are provided with concave and convex notches formed so as to mesh with each other (see FIG. 7).

[0005]

In the present invention, since the inclined surface is provided on the lower side of the fixed plate on the compression surface side, when the empty can is pressed against the fixed plate by the feeding of the movable pressing plate, the empty can is first inclined before being compressed. It is pushed up toward the upper part of the compression chamber along the surface. An empty can placed in the compression chamber with the drinking mouth of the empty can facing up is compressed with its upper part pressed against the ceiling of the compression chamber. The burr that tries to spread is pressed inside the can.
Further, the thickness of the movable pressing plate on the left and right sides of the compression surface is formed so as to gradually increase from the thickness of the central portion of the movable pressing plate, and Since the groove is engraved in a straight line in the vertical direction, when the movable pressing plate pushes up the empty can toward the upper part of the compression chamber prior to the compression of the empty can, the empty can is held in the center of the movable pressing plate and the movable pressing plate It is pushed vertically upwards along the groove. In addition, a plurality of grooves are provided on the ceiling and floor of the compression chamber in parallel with the moving direction of the movable pressing plate, and uneven portions are formed on the upper and lower portions of the movable pressing plate so as to mesh with the plurality of grooves. Since it is provided, the gap is not a single plane, but is uneven,
The detached pull-top and the empty can deformed by compression do not hinder the compression operation. In particular, the upper and lower lids of the empty can are prevented from being caught in the gap. In addition, the separated pull-top can be easily discharged by the discharge port formed widely at the joint between the fixing plate and the empty can stand. Since the discharge port is formed obliquely in a V shape along the inclined surfaces of the empty can stand and the fixing plate, it is not possible to insert a finger into the compression chamber from the outer opening. Further, a concave-convex cut portion is provided on the inclined surface below the fixed plate and the lower portion of the movable pressing plate so as to mesh with each other, or the width of the inclined surface of the fixed plate is set so as to deeply enter into the concave portion of the movable pressing plate. As a result, the gap between the fixed plate and the movable pressing plate during the compression operation can be minimized, and the volume of the empty can can be reduced thoroughly.
