Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to empty cans of drinking water, empty bottles, empty cans for leftover drinks, empty cans with a standard weight or less (hereinafter simply referred to as empty cans), empty cans with a standard weight or more, and Empty bottles (hereinafter simply referred to as empty bottles) are automatically sorted,
The present invention relates to an automatic can sorting device in which the empty bottles are dropped from a sorting case to an empty bottle chute, and the empty cans are moved while being held in the sorting case and are fed to a lower guide of a compression mechanism.

BACKGROUND ART In recent years, drinking water such as juice, beer, and alcoholic beverages has been changing from bottles to cans, and the demand for these cans is increasing, instead of being made of iron or tin plated, and instead of aluminum cans that are press-formed from aluminum sheets.

Most of these empty drinking water cans are generally thrown away in fields, mountains, roadsides, parks, etc., which is a waste of resources and also causes pollution due to empty cans being abandoned. Become.

However, all of these empty cans are collected, and even if they were to be melted down to obtain raw materials, it would not be profitable to produce anything other than aluminum.

Additionally, aluminum cans have drawbacks such as being bulky and requiring high transportation costs.

In order to eliminate the above-mentioned drawbacks, the present applicant previously filed Japanese Patent Application No. 56-174466 (Japanese Unexamined Patent Publication No. 58-76172).
No. 1) discloses an empty can sorting mechanism, in which after empty drinking water cans, etc. are inserted into a required location, the empty cans are horizontally moved by a crank mechanism of a drive device that is activated by closing an insertion door. If a large amount of drinking water remains in the empty can while the empty can is being moved to a predetermined position, or if the empty bottle is heavy, the bottom of the empty can may be opened if the empty can exceeds the standard weight. As soon as the door opens, empty cans and bottles are dropped through a chute into a designated container, and iron cans and aluminum cans that are less than the standard weight pass through the bottom-opening door and are automatically sorted through the same chute. The purpose is to automatically sort out empty cans that can be sent to the compression mechanism.

Therefore, since the structure is such that it can be inserted vertically into the sorting mechanism, empty cans and the like are limited to those that are not deformed and those that have a fixed diameter. This requires a crank mechanism, which complicates the overall structure, increases costs, and has drawbacks such as the fact that if the inserted empty can is deformed, such as by a dent, it is extremely difficult to move it horizontally.

The technical problem of the present invention is that if an empty can can be inserted into the empty can insertion lid and chute formed on the case,
The point is that the empty cans in the chute sorting case can be automatically sorted by their own weight without being affected by the size of the empty cans or the deformation of the empty cans. The structure of the present invention, that is, the technical means for solving the above technical problem is as follows.

An insertion lid/chute for inserting empty cans etc. formed at an arbitrary location on the main body casing, a fan-shaped guide integrally formed with the insertion lid/chute, one end attached to an arbitrary location of the sector-shaped guide, and the other end a pushing arm attached to a rotating member, a rotating member having one end pivotally attached to a fixed arm so as to be rotatable in relation to the advancement or retreat of the pushing arm, and a rotating member rotatable via a connecting member to the rotating member. a sorting case consisting of a movable member attached to the body, a weight discrimination mechanism for discriminating empty cans and bottles, and a positioning member provided on the movable member, and a positioning roller for actuating the positioning member. It consists of an automatic sorting device for empty cans, etc., which is pivotally attached to one end of a fan-shaped guide or actuating piece.

The above technical means works as follows.

In other words, since the empty can insertion lid/chute is formed to be somewhat larger than a youth empty can, it is possible to easily insert an empty beer can including an empty beer can of a size corresponding to the insertion lid, and the insertion lid also serves as a chute. This function ensures that empty cans are fed into the sorting case along the slanted insertion lid, and that the empty cans in the sorting case, which rotates in conjunction with the opening and closing of the insertion lid and chute, weigh more than the standard weight. If so, the weight determination mechanism operates a movable member to drop the empty can into the bottle chute.

Furthermore, if the empty can to be inserted is less than the standard weight, the movable member is not activated and the empty can can be reliably moved to the lower guide of the compressor at high speed while being held in the sorting case.

In addition, the empty cans to be inserted are simply placed on the insertion lid and chute, and all of them are automatically fed into the sorting case, so even if they are slightly deformed or dented, they can be moved to the designated position without any problems. . It can have three functions: a function of supplying empty cans by opening and closing the insertion lid and chute, a function of moving the sorting case, and a sorting function of operating the weight discrimination mechanism while the sorting case is moving.
Moreover, the movement of the empty can does not require power such as a crank mechanism, so the overall structure is simple and compact, and manufacturing costs can be reduced.

Regarding the operation, first, the insertion lid/chute 2 is opened by pulling it toward you, and then when the empty can A is placed on the insertion lid/chute 2, it is sorted while rolling on the insertion lid/chute 2. sent into the case. (Second
(See figure) Next, when the insertion lid and chute 2 is rotated in conjunction with the closing operation, if the empty can A in the sorting case exceeds the standard weight, the adjustment spring 20 of the weight discrimination mechanism 62 is compressed. By doing so, the movable member 1
5 moves in the direction of the arrow, empty cans A in the sorting case
The empty bottles fall into the empty bottle chute 26. (3rd
(See figure) Note that in order to determine the reference weight of the empty can A, the spring 2 is not limited to the spring 2, and any suitable elastic material may be used instead.

Next, if the empty cans fed into the sorting case are less than the standard weight, the movable member 15 in the sorting case will not operate, so as the insertion lid and chute 2 is closed, the push-out arm 21 moves the rotating member 14. When the sorting case holding the empty cans moves forward together with the sorting case holding the empty cans, and reaches the top of the compressor lower guide 25 (position X in FIG. 6A), the positioning piece 17 on the movable member 15 side hits the positioning roller 16. At the same time as the movable member 15 is moved forward by the push-out arm 21 (moved by Y in FIG. 6B), the movable member 15
is opened, and the empty can A contacts the compressor motor drive limit switch 24 and falls into the compressor lower guide 25.

The limit switch 24 rotates the cam 38 and the crank 37 which are integrally formed,
The cam 38 pushes up the drive roller 41 of the hammer lever. The hammer lever 29 rotates around the fulcrum 67, and a recess is formed by the descending hammer 27, and then the piston head 43 moves forward.
The empty can is crushed.

The crushed empty cans fall onto the movable chute 44, and the aluminum cans flow out in the direction of arrow F, completing one cycle.

However, in the case of an empty iron can, it is held in a state where it is attracted to the magnet 49.

Subsequently, the ∨-shaped cam 46 is struck by the crank roller 40, and is rotated in the direction of arrow E by the operation of the swing rod 47 connected thereto.

Furthermore, by being rotated, the magnet 49
is separated from the movable chute 44 and the suction force is reduced, so the empty iron can is detached from the movable chute and falls to the E side.

Figures 7 and 8 show other embodiments of the means for feeding empty cans into the compression mechanism.

An operating rod 67 is installed at an arbitrary location on the left side wall of the fan-shaped guide 8.
The proximal end is fixed, and a positioning roller 68 is rotatably attached to the distal end.

A positioning lever 69 is attached to the flat surface 61 of the movable member 15, and is locked by the lowering of the positioning roller 68 of the operating rod 67, which rotates together with the fan-shaped guide 8.

As described above, the movable member 15 has a hinge 60,
It is attached to the rotating member 14 of the sorting case via 60.

The empty can A in the insertion lid and chute 2 moves forward while being held between the rotary member 14 and the movable member 15 of the sorting case, and as shown in the figure, the positioning roller 68 rotates along the slope of the positioning lever 69. While moving, the movable member 15 is simultaneously lowered and pivoted upward.

As a result, the empty can between the rotating member 14 and the movable member 15 falls into the lower guide 25 of the compression mechanism.

According to the device of the present invention, the empty cans to be inserted can be smoothly fed into the sorting case with a single touch by simply placing them on the insertion lid and chute, so there will be no problem even if there are dents on the surface of the empty cans. You can move to a predetermined location and achieve your desired goal.

In addition, it is possible to have three functions: the function of supplying empty cans by opening and closing the chute on the insertion lid side, the function of moving the sorting case, and the sorting function of operating the weight discrimination mechanism while moving the sorting case. Since the movement of the empty can does not require power such as a crank mechanism, the overall structure is simple and compact, and manufacturing costs can be reduced.
