Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the collection and storage of used empty containers.

[0002]

2. Description of the Related Art From the viewpoint of environmental beautification, a trash box is usually installed in the vicinity of a food and beverage shop or a vending machine in order to collect empty containers discharged after eating and drinking. Furthermore, in recent years, the recycling movement has been increasing, and a trash box for separate collection is being installed for resource recycling. However, it is difficult to secure a space for installing a trash can in a small-scale sales office or a vending machine, and it is not possible to install a trash can with a sufficient storage capacity for the amount of empty containers to be discharged. In some cases.

[0003] In a trash box installed for the purpose of collecting empty containers limited to products handled by the vending machine, such as a trash box adjacent to the vending machine, it is actually excluded from the object for the purpose of installation. Many kinds of garbage are thrown in, which is annoying to the collectors. As a measure to prevent this, measures such as matching the shape of the input port of the trash box to the target empty container are taken, but since the input port is open upwards, dust and It cannot be an effective means to prevent the input of small garbage such as cigarette butts.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to prevent the entry and entry of foreign matter other than the empty container to be collected and to collect only the target empty container.

[0005]

[Means for Solving the Problem] * 1 The technical means of the present invention for solving the above-mentioned problems is "a hollow duct main body connecting an empty container input side and an empty container discharge side, and At the opening end on the charging side, a charging port which can be set in a downward opening posture, and a non-return means which can push back an empty container but which prevents reversal are provided. ” is there.

The above technical means operates as follows. The recovery duct is installed so that the input port of the empty container opens downward, but the empty container mainly inserted into the duct is checked by a check means such as an annular check edge body provided at the input port. Since it does not come back, it does not fall off the main body of the duct. The non-return edge means a non-return structure attached to a peripheral portion of an opening end of a duct main body which is a charging port of an empty container, and includes a plurality of non-return pieces and a plurality of swingable support rods. Composed by. In addition, since the input port of the empty container opens downward, it is difficult for small dust, cigarette butts, etc., and rainwater, sand dust, etc. to enter. In addition, empty containers that are sequentially loaded into the duct main body do not return, so the empty containers that are loaded first move in the duct main body in the form of being pushed (pushed) by the empty containers that are loaded later. Then, it is sent to the outlet.

The downward direction is not limited to the vertical downward direction and includes a downward direction close to the horizontal direction.

[0008]

The present invention, having the above-mentioned structure, has the following unique effects. Since the input port of the empty container is opened downward, it is difficult for foreign objects other than the target empty container to enter and enter, and even if it is entered and entered, it falls from the downward input port, so the target empty container Only can be collected. Further, by sequentially pushing the empty container into the duct main body from the charging port, the empty container can be pushed out to the discharging port without using power.

[Others] * In the paragraph 1 of paragraph 2, "the tubular main body of the duct has an inner diameter larger than that of the hollow empty container, and is elastically deformed vertically toward the tip end with the peripheral edge of the charging port as the base end. Since the inner diameter of the recovery duct of the hollow empty container is minimized, the recovery duct is made more compact by providing an annular check edge body composed of a plurality of check pieces with possible free parts. The installation space is small.

Here, since the free end portion of the check piece, which is continuous with the base end portion, can be elastically deformed in the vertical direction, the duct main body is so arranged that the hollow empty container penetrates the annular check edge body. It can be forced into. * 3 In the above item 1 or 2, by "configuring the duct main body to have flexibility", the position of the inlet can be freely set without being restricted by the relationship with the position of the outlet. It is possible, and according to the shape of various mounting objects,
A recovery duct can be installed to fit it. * 4 In the case of "providing reverse movement resistance giving means for giving a predetermined movement resistance to the movement in the direction opposite to the pushing movement direction of the empty container at the back of the charging port", a duct-based charging is used. Reverse movement of empty containers that are thrown in at the back of the mouth (for example, one to several empty containers separated from the input port) is prevented. Unlikely to occur. * 5 With the above-mentioned recovery duct, a "recovery device consisting of an accommodation section for accommodating an empty container placed on the discharge side of this recovery duct" can be used to easily insert an empty container. It is possible to install a charging port at a position and install a sufficient empty container accommodating portion in a place where it does not disturb or an empty space. In addition, since it is not necessary to install it in a conspicuous place like a conventional trash can in which the inlet and the storage unit are integrated, the surrounding landscape and aesthetics are not spoiled. * 6 In paragraph 5 of paragraph 5, "A device for collecting empty containers attached to a vending machine for beverages, in which the input port is located on the front side of the vending machine equipped with the sales function section or the side surface adjacent to the front side. It is easy to use because it is attached to the vending machine. Further, in the case where "the storage section is continuously formed above the top of the vending machine", the space following the top of the vending machine can be effectively used.

Further, in the case of "the storage section is a box body which is arranged in parallel along the side surface of the vending machine and which is flat to the left and right, and the recovery duct is provided in front of the box body", Easy to install in parallel with vending machines.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention described above will be described in detail with reference to the drawings. An example of an empty container recovery duct is shown in FIGS. The duct main body (1) is a tubular body having flexibility as a whole, and one opening end thereof is an input port (2) of the empty container (4) and the other opening end thereof is a discharge port (21). The charging port (2) is provided with an annular check flange (3) which prevents the charged empty container (4) from returning. Since the duct main body (1) is flexible, by placing the fixing band (11) that is wrapped around the duct main body (1) and clamps the duct main body (1) at a predetermined position, the insertion port (2) faces downward. It is possible to freely set the bending direction, the inclination angle, etc. of each part after being attached so as to be. It is also possible to fix the duct main body (1) to objects of various shapes.

An inlet for an empty container (4) mainly consisting of the duct (1)
As shown in FIGS. 4 and 5, the check bar (3) installed in (2) is an annular outer frame fitted to the open end of the duct main body (1).
Inside (31), mouth (37) for passing empty container (4)
And a disk-shaped rubber lid (32) with a notch (36) following this,
It has a structure in which an annular spacer (33) for firmly fixing the peripheral edge of the rubber lid (32) and the outer frame (31) to each other. The check edge body (3) is fitted onto the open end of the duct main body (1) and screwed from the outside.

The disk-shaped rubber lid (32) constituting the check edge body (3) is cut at a position where the circle is divided into six equal parts from a hole portion at the center thereof to a position inside the periphery by one circumference ( 36), so that the rubber lid (32) has six fan-shaped check pieces (3).
0) is formed. The apex portion (free end portion) corresponding to the central angle of the fan shape of each check piece (30) is formed in an arc shape. still,
These free parts are arranged on a circumference smaller than the diameter of the body of the empty container (4) introduced from here. Therefore, the rubber lid (32) has a mouth (37) smaller than the apparently empty container (4).
Has been formed. Further, each check piece (30) is provided with a discard hole (35) (35) to facilitate elastic bending. Further, the mouth portion (37) and the waste hole (35) facilitate the removal of small foreign matter, rainwater, sand and the like that have been thrown in through the charging port (2) to the outside.

When the empty container (4) is pushed into the mouth portion (37), each check piece (30) of the check piece (30) (30) group formed on the rubber lid (32) is removed. It is pushed in while deforming the free end side of the tip part upward. Then, when the empty container (4) is pushed into the duct main body (1) to a predetermined depth, each check piece (30) elastically returns to the horizontal state, and the rubber lid (32) has a horizontal plane as a whole. Returning to the form, the empty container (4) is held (supported) by each check piece (30) (30) in this state.

A rubber lid (32) used for the check edge body (3)
The material is not limited to rubber, but may be formed of a material such as synthetic resin having elasticity similar to rubber. When the empty container (4) to be collected is lightweight, the empty container (4) can be supported by the rubber lid (32) having a plurality of check pieces (30) (30) as in the above example. When the weight is comparatively heavy, it is possible that the supporting force is insufficient only with the check pieces (30) (30), or the rubber lid (32) is deteriorated early due to excessive support. In such a case, as shown in FIG. 6, the supporting force of the empty container (4) is assisted inside the duct main body (1) at the position of two empty containers (4) from the inlet (2). It is desirable to install the support piece (300). The supporting piece (300) of this example has its base end attached to the inner wall of the duct main body (1), and its free end is provided in a posture in which it is directed obliquely inward toward the downstream side in the pushing direction. Multiple support pieces (30
0) (300) are arranged in a ring. Therefore, this support piece
The empty container (4) pushed between (300) and (300) can be pushed further inward, but it moves in the opposite direction due to the frictional force between the body of the empty container (4) and the free end of the support piece (300) (300). Is kept blocked. The support piece (300) is formed as a pair of support pieces or a plurality of support pieces (300) (300) on the same circumference of the duct main body (1) according to the required auxiliary capacity. It is conceivable that they are arranged facing each other. This support piece (300) (300)
Functions as a means for applying reverse movement resistance, and an empty container is
It will be installed in the depth of one to several in (4).

An empty container in addition to the recovery duct of the above example
It is conceivable to change the shapes of the inlet (2) and the duct main body (1) and the structure of the check edge body (3) according to the shape of (4) and the charging direction. As shown in FIG. 7, the duct main body (1) may have a rectangular cross section. Empty container (4) in this example
Is inserted from the inlet (2) which is kept horizontal and opens downward.

The non-stop edge body (3) of this example is composed of a pair of non-stop pieces (30).
Each non-return piece (30) is composed of an oscillating support rod. This support rod is composed of a pair of arms (39) (39) provided on each long side of the rectangular opening end of the duct main body (1) and a support rod (38) connecting the free ends thereof. The free end of the arm (39) can be moved up and down at an angle from the horizontal position to the fixed end along the inner surface of the duct main body (1), and the free end does not fall below the horizontal position. A stopper (391) is provided below the (39).

When the pair of arms (39) (39) is in the horizontal state, the space between the support bars (38) (38) connected to the arms (39) (39) is filled with empty containers. It is set to be narrower than the minimum width of (4) (in the case of a barrel type container, its diameter). Therefore, the empty container (4) pushed into the duct main body (1) is the duct main body.
It does not fall from (1). When the support rod composed of the support rod (38) and the arm (39) is swung upward, the support rod (3
8) The spacing of (38) becomes wider than the diameter of the inserted empty container (4), and when the empty container (4) is pushed further, these support rods are
