Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for reliably and automatically selecting empty cans of used vending machines from iron cans and aluminum cans, and further to empty cans for leftover drinks, The present invention relates to a processing device that can automatically sort and collect unnecessary materials such as bottles.

[0002]

2. Description of the Related Art In most conventional empty can processing machines, when sorting, the materials of empty cans are crushed without distinction and then visually sorted into iron cans and aluminum cans. Further, even if the automatic sorting method is adopted, it is indispensable to perform the sorting and re-inspection by the human eyes.

[0003]

Therefore, with the spread of automatic vending machines today, there has been an urgent need to develop the most reliable automatic selection method and its apparatus. The present invention eliminates the drawbacks of such a sorting function, and provides an automatic sorting compression processing apparatus with high certainty that is capable of automatically sorting iron cans and aluminum cans as well as collecting bottles and unfilled cans. It was done by.

[0004]

In order to solve these drawbacks, the sorting function is divided into two parts so that they can function. In the first part, the opening / closing operation of the tow type rotary cylinder 3 of the insertion port is performed every time one empty can 27a is inserted so that a certain time can be secured, and the operation time of the second part is based on this operation. Is set so that the sorting operation of empty cans and bottles can be performed in accordance with the first part. That is, lower the handle 7 by hand with the tou-shaped rotary cylinder 3 at the inlet,
It is possible to secure a certain period of time by opening the tou-shaped rotary cylinder 3 at the opening of the can, and then insert the empty can 27a into the open tou-shaped rotary cylinder 3 with the other hand and let go. By automatically raising the handle 7 by the operation of the spring 6 and closing the Toyu type rotary cylinder 3, the compression processing time of the empty can 27b is secured sufficiently, and the charging can 27a is positioned at the outlet on the opposite side located inside the main body 1. It is automatically guided and sent to the balance stand 14. If the input can 27a contains leftover drinks or is a bottle, the balance stand 14 is out of balance because the weight is heavier than the empty can. The right half of 14 inclines clockwise, and heavy empty cans and bottles are dropped into the Ha box.

The second part is that the normal empty can 27b inserted by the pressing operation is pressed by the operation of the pressing machine to become the flat waste plate 27c, and then the permanent magnet 35 installed on the press compression plate 28 is attracted. By the sorting operation, the flat waste plate 27c after compression of the iron can and the aluminum can is distinguished, and the flat waste plate 27c of the iron can is attracted to the permanent magnet 35 of the press compression plate 28 and left with the intermediate press compression plate 29. Go and
After that, the permanent magnet 35 is separated from the intermediate press compression plate 29, and the attraction action disappears, so that the permanent magnet 35 is automatically dropped to be discharged. Further, in the case of the flat waste plate 27c of an aluminum can, the structure is such that it is not adsorbed and can be directly dropped and discharged.

The advantage of separating the first and second sorting operations is the second one.
The sorting operation time is set based on the first operation, and in the first part, the processing time has to be performed while opening and closing the Toyu-type rotary cylinder 3 that is always the can 27a. There is a point. That is, the main purpose is that the two empty cans 27b and 27c cannot be inserted at the same time, and in the second part, the first part is installed on the upper part of the press compression plate 28 if the charging time is short. The fall prevention plate 40 is provided so as to prevent a plurality of empty cans 27b from being inserted into the press compression plate operating portion 26.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Since the present invention has taken the above-mentioned means, it is impossible to automatically put empty cans at high speed for processing, but it is possible to secure a constant time required for processing instead of manual operation. It is also possible to incorporate a set automatic feeding function, and in this case as well, the setting time is basically based on the manual operation time, so that there is no variation in the sorting operation and a safer operation than ever before. It is possible to adopt a reliable selection processing function that does not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3 and 4. 1 and 4,
A tou-shaped rotary cylinder 3 is placed in an opening 2 in the upper portion of the body side plate 1, and a terminal 6 is twisted and fixed by the pin 8 and the bracket 4 with a pin 5 centered on a bracket 4 provided inside the body side plate 1. Thus, the Toyu type rotary cylinder 3 is installed so that it can be always held in the closed state. A knob 7 is provided on the tow type rotary cylinder 3 so that it can be easily opened and closed by hand. The tou-shaped rotary cylinder 3 is provided with a stop rib 9 on the upper side and stop pins 10 on both sides, and is configured to always keep a closed state unless it is opened by hand. In addition, stop pins 11 are provided on both sides of the lower part of the toyo type rotary cylinder 3,
It also plays the role of a stopper when the toy-type rotary cylinder 3 is opened.

Side plates 12 for guiding empty cans are provided at the front and rear of the apparatus, and a balance stand 14 is provided with a pin 13 provided between the front and rear side boards as a core rod. A balance weight 15 is provided on the right side of the balance stand 14, and a left side is provided on the left side. A minute adjustment weight 16 is provided in the balance adjustment unit 14 so that the balance base 14 is adjusted to the left with a slight balance. 17 is a fixing screw, 18 is a weight 1
6 is a fixing nut, 19 is a stopper of the balance base 14, 20 is a guide plate of an empty can, and 26 is an insertion port of a working portion of the press compression plate.

FIG. 1 shows a state where the brake motor 21 is stopped, and shows a state where the press crank 22 is stopped in a horizontal state. That is, FIG. 1 shows the start time and the end time of the press work, and the proximity switch 23 of the brake motor 21 is set to be in a detectable state on the proximity plate 25 installed on the crank disk 24 so that it can be stopped by the detection. Has been done. It should be noted that the crank disk 24 rotates once clockwise when it is operated.

In FIGS. 1, 2 and 3, the empty can 27b dropped on the press compression plate operating portion 26 is moved to the right of the press compression plate 28 by the press crank 22 so that the intermediate press compression plate 2 is moved.
The empty can 27b is pressed against the fixed compression plate 30 via 9 and the empty can 27b is compressed and processed into the flat empty can 27c. The press compression plate 28 is moved rightward by four rollers 31 along a side groove 34 formed by an upper side plate 32 and a lower side plate 33.

Permanent magnets 35 of 110 to 130 gauss are installed at 3 to 4 places (3 places in FIG. 3) on the press compression plate 28, and through the holes 36 drilled so as not to contact the intermediate press compression plate 29. Empty can 27c directly flattened
With the left-hand movement of the intermediate press compression plate 26, it is sucked and held and left-handed together. The intermediate press compression plate 29 is formed of an SS material having a thickness of about 12 mm, and is held by the press compression plate 28 via the guide pin 37 in a state in which they can be intimately adhered to each other by the expansion and contraction operation of the spring 38. Further, the intermediate press compression plate 29 may use a non-magnetic steel material. The iron empty can 27c compressed by the intermediate press compression plate 29 and the fixed compression plate 30 and flattened is compressed by the intermediate press compression plate 29 by the attraction force of the permanent magnet 35 having a height of 10 to 12 mm protruding into the hole 36 of the intermediate press compression plate 29. The press compression plate 28 and the intermediate press compression plate 29 are pulled apart by the stop pin 39 at the leftward inversion position, that is, the horizontal stop point of the press crank 22, while being held together with the plate 29, and the hole 3
When the permanent magnet 36 comes out of the 6, the permanent magnet 35 at the same time releases the flattened crushed empty can 27c, and then drops into the throw-in box A by its own weight. By the way, the opening distance between the press compression plate 28 and the intermediate press compression plate 29 is 10 to 12 mm, and the space is adjusted by inserting and removing the stop pin 39.

In FIG. 2, when the empty can 27c compressed by the intermediate press compression plate 29 and the fixed compression plate 30 is an aluminum can, the permanent magnet 35 cannot be adsorbed, so that it is flatly crushed directly into the charging box. The empty can 27c is dropped and thrown in. A comb-shaped stopper 42 supported by a support frame 41 is installed under the press compression plate 28, and when the intermediate press compression plate 29 is opened leftward in accordance with the movement of the press compression plate 28, the empty can 27b is opened. It plays the role of preventing falling. Also, if you accidentally continue to use empty cans 27
A fall prevention plate 40 is installed above the press compression plate 28 as a protection plate so as not to drop into the press compression plate operating portion 26 when d is input.

Photoelectric switches 43 are installed on both sides in order to confirm whether or not the empty can 27b is surely inserted into the press compression plate operating portion 26. The photoelectric switch 43 is used for confirmation by projecting the operation signal of the brake motor to the proximity switch 23. Together with the confirmation of, it plays a role in starting. The time required for one rotation of the brake motor 21 is set to 50% or less of the time required based on the operating time of the Toyu type rotary cylinder.

[0015]

The effect of this construction is that, although many sorting apparatuses have conventionally been operated by an electronic method or an electromagnetic method, the degaussing measures are insufficient, and high-speed sorting or the like is sufficient for sufficient sorting. I couldn't say. The device of the present invention uses a permanent magnet, and in order to reliably perform the sorting operation by mechanical operation,
The sorting time is based on the manual loading time, and the press compression work is set based on this. At the same time, the sorting function for iron cans and aluminum cans uses a mechanical system that instantaneously disconnects the permanent magnets, so there is no effect of remanent magnetism compared to the electromagnetic system, and the above-mentioned sufficient time is secured and the sorting ability leap forward. The greatest effect is that it is configured so that it can be improved and the two effects can be combined.
