TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty container collecting machine for reducing empty containers such as empty cans and empty plastic bottles for collection.
[0002]
[Prior art]
The above empty container collecting machine compresses or cuts empty containers such as empty beverage cans or plastic bottles to reduce the volume, and then collects the empty containers in a collecting box. FIG. 14 is a perspective view showing a state where a main body door of the conventional empty container collecting machine is opened, and FIG. 15 is a front view schematically showing the inside of the main body. 14 and 15, particularly in FIG. 14, the charging mechanism 2, the distribution mechanism 3, the receiving chute 4, the return chute 5, the volume reduction mechanism 6, the collection box 7, and the like are installed in the main body 1. The main body door 8 is provided with an empty container input port 9, a return port 10, and the like. When the empty container collecting machine detects that an empty container (empty can or empty plastic bottle) 11 (FIG. 15) has been inserted into the charging mechanism 2 through the empty container input port 9 by the feed sensor, a feed wheel (not shown) is used. The empty container 11 is conveyed to the distribution mechanism 3 by rotating 2a.
[0003]
The sorting mechanism 3 receives the conveyed empty containers 11 on a pair of left and right rotating rollers 12 and rotates the empty rollers 11 counterclockwise in FIG. The bar code on the empty container 11 is read. As a result, if the container is a registered container, it is determined that the container is acceptable, and the portal-shaped distribution plate 14 (FIG. 15) is shaken clockwise to put the empty container 11 into the receiving chute 4. If the container is an unregistered container, it is determined that the container is unacceptable, the rotation roller 12 is rotated in the clockwise direction, and the distribution plate 14 is swung counterclockwise to put the empty container 11 into the return shooter 5. This return container is returned to the return port 10 via the return shooter 5. On the other hand, the registered container put into the receiving shooter 4 is reduced in volume by compression, cutting, or the like by the volume reducing mechanism 6, and is dropped into the collection box 7 below and collected.
[0004]
FIG. 16 is a front view showing the operation of the volume reducing mechanism 6 for cutting and reducing the volume of the PET bottle in the order of (1) to (3). In FIG. 16, a volume reduction mechanism 6 includes a pair of left and right press shaft teeth 17 driven by a volume reduction motor 15 via a belt mechanism 16 and a reduction gear mechanism (not shown), and press shaft teeth 17 via a belt mechanism 18. And a pair of left and right paddles 19 interlocked with the paddle 19. When the empty container collecting machine detects the insertion of the empty container 11, the rotation of the volume reduction motor 15 is started, and the empty container 11 inserted by the distribution mechanism unit 3 is received on the press shaft teeth 17 in (1). The empty container 11 is cut between the press shaft teeth 17 while being pressed by the paddle 19 as shown in (2), and is collected in the collection box 7 as shown in (3).
[0005]
The volume reduction mechanism 6 shown in FIG. 16 is for processing empty containers (pet bottles) 11 without separation, and FIG. 17 shows the volume reduction mechanism 6 for separating empty cans into aluminum cans and iron cans and compressing them. Here is an example. 17, the volume reducing mechanism 6 is driven by the crank mechanism 20 and reciprocates left and right in FIG. 17 in a vertical state. The press plate 21 is opposed to the press plate 21 and vertically fixed on both front and rear sides thereof. And two backing plates 22 and 23. In the empty container (empty can) 11, the iron can is compressed on one of the left and right sides of the press plate 21, and the aluminum can is compressed on the other side.
[0006]
The operation of receiving or returning the empty container 11 is the same as that of the case of the PET bottle, but when the empty can is inserted from the input port 9, the aluminum sensor (not shown) distinguishes between the aluminum can and the iron can. Now, for example, if the iron can is compressed between the press plate 21 and the stiffener 22 and the aluminum can is compressed between the press plate 21 and the stiffener 23, if the empty container 11 is determined to be iron, As shown at (1) in FIG. 17, when the press plate 21 reaches the left end (bottom dead center) of the stroke and the left position sensor 24 detects the press plate 21, the distribution plate 14 is moved clockwise as shown. By shaking, the empty can 11 is dropped between the press plate 21 and the backing plate 22. The empty can 11 is received by a receiver 26.
[0007]
Next, the press plate 21 moves rightward and compresses the empty can 11 at the right end (top dead center) of the stroke as shown in (2) of FIG. As shown in (3) in FIG. 17, the reduced volume of the empty can 11 is dropped and stored in the iron can collection box 7a on the right side by the retraction of the press plate 21. Although the above is the case of an iron can, when it is determined that the can is an aluminum can, the distribution mechanism unit 3 drops the empty can 11 when the right position sensor 25 detects the press plate 21. As a result, the aluminum can is compressed between the press plate 21 and the backing plate 23 and stored in the aluminum can collection box 7b on the left side.

[Problems to be solved by the invention]
In the above-mentioned conventional empty container collection machine, the collection box becomes full in a short period of time depending on the installation location, and it is desired to increase its storage capacity. In particular, when the empty containers are sorted and collected, the collection boxes are classified according to the types of the empty containers, so that one collection box tends to be filled first due to the uneven collection of the types.
[0010]
Therefore, an object of the present invention is to make it possible to easily increase the storage capacity of a collection box of an empty container collection machine.
[0011]
[Means for Solving the Problems]
In order to solve the above problem, the present invention is to reduce the volume of an empty container inserted from a container insertion port on the front of the main body by a volume reduction mechanism, and then drop the empty container into a collection box below the volume reduction mechanism. In the empty container collecting machine to be collected, a side cabinet having a preliminary collection box is installed adjacent to the main body, and a common through window is opened in the side walls of the main body of the side cabinet and the empty container collecting machine main body facing each other. A shooter that guides the empty container dropped from the volume reduction mechanism to the preliminary collection box through the through window is provided, and the empty container after the volume reduction processing can be collected in the preliminary collection box via the shooter. (Claim 1).
[0012]
According to the invention of claim 1, a spare collection box is additionally provided outside the empty container collecting machine, and the empty container after the volume reduction processing can be collected in the spare container via the chute. It is possible to greatly increase the capacity of the collection box.
[0013]
In the invention of claim 1, the chute is attached to the empty container collecting machine so as to be able to advance and retreat, and the empty container is directly dropped on the collection box in a state where the chute is retracted from the volume reduction mechanism, and the chute is moved. It is preferable that the empty container is dropped into the preliminary collection box via the shooter in a state where the container is advanced to the volume reduction mechanism (claim 2). Thus, when one of the collection box and the preliminary collection box becomes full, the collection of empty containers can be easily shifted to the other simply by moving the shooter forward and backward. In this case, if an auxiliary shooter that is continuous with the shooter in the advanced state is provided, the length of the main shooter can be shortened by that much, and handling can be simplified (claim 3).
[0014]
In the invention of claim 3, it is preferable to provide a guard shooter for preventing the empty container from jumping into the auxiliary shooter when the shooter is retracted (claim 4). The empty container after the volume reduction processing does not always fall directly below the volume reduction mechanism, and may adhere to the press shaft teeth or the like and be blown to the side. In this case, if the reduced volume container falls onto the auxiliary shooter, an empty container to be collected in the collection box is collected in the preliminary collection box. Therefore, if the guard shooter described above is provided, an empty container can be reliably collected in a predetermined collection box.
[0015]
In the invention of claim 4, it is preferable that the shooter and the guard shooter are integrally formed in a mountain shape, whereby the shooter and the guard shooter can be simultaneously advanced and retracted with a simple mechanism (claim 5).
[0016]
2. The shooter according to claim 1, wherein in the case of an empty container collecting machine that separates empty containers by type and drops the empty containers after volume reduction processing from different outlets of the volume reduction mechanism unit by type. 3. Is connected to any one of the outlets, and the empty container that has fallen from this outlet is collected in the spare collection box via the shooter.
[0017]
