Abstract

PURPOSE:To put the empty can compressing device for processing an empty can to practical use by providing a distributing means, etc., for detecting a material of a throw-in object, guiding it to a compressing part, when the material is a metal, and guiding it to a foreign matter containing part without compressing it, when it is a nonmetal. CONSTITUTION:For instance, when an empty can 7 made of aluminum is thrown in from a throw-in port 5, it passes through the part of a nonmetallic core 19 and it is detected that the throw-in object is the empty can 7 made of aluminum and it is outputted to a central processing part. The central processing part outputs a command to a compression control part and a selection lever control part, and the empty can 7 is led to a compression roller side by a selection lever 17 and compressed by pre-compression rollers 13, 15 and compression rollers 16, 18. In the end, it is contained into a containing case 24 for aluminum by a lever 26. When the throw-in object is nonmetal, it is guided to a foreign matter containing part, and on the other hand, other metallic foreign matter than a can led into a compressing part is not compressed but guided to the foreign matter containing part, when overload driving in the compressing part is detected. In such a way, the generation of abnormality in the compressing part is prevented, and the compression processing of an empty is executed.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an empty can compression device.

(Prior Art) In recent years, various canned beverage products, typified by beer and soft drinks, have become widespread, but on the other hand, disposal of empty cans has become an important issue in terms of environmental conservation. For this reason, the spread of empty can compression equipment for processing empty cans,
There is a strong need for practical application. As an empty can compression device, for example, a configuration in which loaded empty cans are compressed with a built-in compressor is generally considered.

(Problem to be solved by the invention) By the way, when it comes to popularizing and putting empty can compression equipment into practical use,
One of the important issues to be solved is to be able to take measures to prevent malfunctions or damage caused by foreign objects other than empty cans, even if they are accidentally thrown into the equipment regardless of fault. In other words, if a foreign object such as a glass bottle is thrown in! However, if a lump of metal, etc. made of the same material as the empty can is thrown in, an excessive load will be applied to the compression roller, causing damage to the roller itself, failure of the roller drive unit, etc. ? It is. In particular, in practical use, it is easy to imagine that at least a means for identifying whether the input material is metal or non-metallic will be provided, so it is important to deal with the case where a metal object that is difficult to compress is input.

The present invention has been made in view of the above, and an object of the present invention is to provide an empty can compression device that can compress empty cans with high reliability. 1 [Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides an apparatus for guiding loaded empty cans to a compression section and compressing them. If the material of the material is metal, it is guided to the compression section, and when the material of the material of the material is non-metal, it is guided to the foreign material storage section without being compressed. The main point is that the distribution means for guiding the input material and the guiding means for guiding the input material to be compressed to the oscillating storage section without being compressed when overload drive in the compression section is detected. shall be.

(Function) In the empty can compression device according to the present invention, when the material of the input material is metal, it is guided to the compression section, and when the material of the input material is non-metal, it is introduced into the foreign matter storage section without being compressed. On the other hand, even if an object is guided to the compression section, if an overload drive in the compression section is detected, the object is guided to the foreign object storage section without compressing force, so that the material is guided to the compression section. This prevents abnormalities from occurring.

(Example) A detailed explanation of the invention will be given with reference to the drawings.

3 and 3 are a cross-sectional view and a processing circuit block diagram of the empty can compression device 1, respectively.

First, the configuration of the empty can compression device 1 will be explained. In FIGS. 1 and 2, reference numeral 5 denotes an input port into which empty cans 7 to be compressed are input, and from this input ['' 5 there is a guide passage 9
3, this guide path 9 branches in the middle, and the empty cans etc. that are thrown in are separated from foreign objects other than empty cans 1.
Foreign matter storage box 11 or preliminary compression roller 1 for storing 0
It leads to between 3 and 15.

On the way from the branching part of the guide path 9 to the foreign matter storage box 11, there is a pre-compression roller 1.3.
15 and this pre-compression 1''-ra 13, 15. Near the end of the guide path, there is a removal path 61 that guides empty cans and the like removed by the action of the S and Q removal mechanism 60 to the foreign matter storage box 11. is connected.

A compression roller 16.18 is provided below the pre-compression roller 13.15 to further completely compress the pre-compressed empty can 7, and a steel can containing the compressed empty can 7 is provided below the pre-compression roller 16.18. A storage box 20 for aluminum cans and a storage box 24 for aluminum cans are provided. In addition, a first sorting lever 17 constituting a sorting means for sorting out empty cans, etc. is provided at a branching part of the guide passage 9.
In the discharge section of No. 8, there is a second section that distributes steel and aluminium.
A selection lever 26 is provided, and each drive is controlled by a control section 31, which will be described later.

On the other hand, a part of the guide passage 9 on the way from the input port 5 to the branch part is formed of a non-metallic material 19, and an electromagnetic induction coil 21 is wound around the outer periphery of the guide passage 9. This electromagnetic induction coil 21 forms a magnetic field within the non-metallic core 19, and the third
As shown in the figure, this constitutes a material detecting means for determining the type of an empty can or the like put in by the material detecting section 22 of the control section 31. Specifically, as shown in Figure 4,
The electromagnetic induction coil 21 is connected to an AC power supply 23 in series with a capacitor 25, and the impedance detection circuit 27 detects the passage of an empty can or the like through the non-metallic core 19 when a high frequency current is supplied by the AC power supply 23. The accompanying change in the impedance of the electromagnetic induction coil 21 is detected as a change in the terminal voltage of the capacitor 25, and the empty can or the like is determined based on this change. As a result, iron, aluminum, foreign objects other than cans, empty cans, etc. are determined to be absent in descending order of input impedance.

As shown in FIG. 5, the removal mechanism 60 has a solenoid door 3 and an removal lever 65 that is operated by the drive of the solenoid 63. The solenoid 63 is driven by the solenoid control section 67 of the control section 31. controlled. This removal mechanism 60 is used when the control unit 31 Under the control of the pre-compression rollers 13 and 15, the υ1 removing mechanism 60, the elimination passage 61, the pre-compression rollers 13 and 15 and the solenoid control section 67 constitute a guiding means. This is to remove the foreign matter and guide it to the foreign matter storage box 11 via the rejection passage 61.

The control section 31 includes a central processing section 33, a compression device control section 35, and a sorting lever control section 37 in addition to the material detection section 22 and the solenoid control section 67. The central processing section 33 controls the operation of the entire apparatus, and also controls the compression device control section 35, the selection lever control section 37, and the solenoid control section 67 in response to the classification results from the material detection section 22. The compression device control unit 35 includes the central processing unit 33
The compression motor 39, which rotates the preliminary compression rollers 13, 15 and the compression rollers 16, 18 under the control of the compression motor 39, is controlled. In particular, the compression device control unit 35
has a function of monitoring the load condition of the compression pressure motor 39, and detects when an overload condition is occurring such as when an empty can or the like that is difficult to compress is guided to the pre-compression []-ra 13, 15. In order to detect and eliminate this by
- It has a function of rotating the wheels 13 and 15 in the reverse direction and notifying the central processing unit of this fact. The sorting lever control section 37 is
The first sorting lever 17 under the control of the central processing section 33
The position of the second sorting lever can be controlled. The solenoid drive unit 67 receives a command from the central processing l!lj unit 33 based on a notification signal input when the preliminary compression roller 13.15 is rotated in reverse by the compression device control unit 35 as described above. This is to drive the solenoid 63.

In the vending machine shown in FIG. 1, 41 is a product display room, 43 is a selection switch group, 45 is a coin insertion slot [1, 47 is a bill insertion slot, and 49 is a product output port.

Next, the operation of this embodiment will be explained.

For example, as an empty fh 7 made of aluminum is introduced from the input port 5 and passes through the non-metallic core 19 in the guide passage 9, the material detection unit 22 detects a change in the input impedance of the electromagnetic induction coil 21 and inputs the aluminum. The central processing unit 33 is informed that the object is an empty aluminum can 7. Upon receiving this detection result, the central processing section 33 issues a command to the compression device control section 35 to rotate the compression motor 39, and roughly fills the empty cans 7 and turns the first sorting lever. A necessary command is output to the sorting lever controller 37 to set the second sorting lever 26 to the position where it compresses the aluminum cans 17 and leads it to the 1-ra side, and sets the second sorting lever 26 to the position where it leads to the aluminum can storage box 24. , the loaded empty can 7 is pre-compressed: 1-ra'13.'15 and the compression rollers 16, 18
After being compressed by C, it is stored in the storage box 24 for aluminum cans.

If the empty can 7 is made of steel, the central processing unit 33 moves the second sorting lever 26 to guide the empty can 7 to the steel storage box 20 (at position t7). Set.

On the other hand, even if it is iron or aluminum, if it is not an empty can but something difficult to compress such as a lump is input, the input is guided to the pre-compression rollers 13, 15 by the action described in 1). However, when the compression device control unit 35 detects that the compression motor 39 is overloaded due to the compression of such an object, it determines that this is a metal foreign object 69 that is difficult to compress and eliminates it. Preliminary compression roller 13,1
Rotate 5 in the opposite direction. Along with this reverse rotation, the metal popper 69
As shown in FIG. 6, the central processing section 33 is pushed up by the pawl 62 installed in the pre-compression port 1-ra 13, 15 (pushed), so that the central processing section 33 is activated by the solenoid control section 6 at a predetermined timing.
When the solenoid 63 is driven through IIh! as shown in FIG. , <The removal lever 65 pushes the pushed-up metal foreign object 69 into the removal path 61, and the six metal foreign objects pushed out are pre-compressed during the reverse rotation Φλ [-1- guided by the claw 62 of the lever 15 and released] The material is discharged into the guide path 9 leading to the object storage box 11.

Next, from input [15, for example, a glass bottle is input,
The material detection unit 22 detects a change in the input impedance of the electromagnetic induction coil 21 and detects whether the input material is a foreign object 10 other than an empty can.
It is output to the central control unit 33 that r is present. Central control unit 3
3 receives this detection result (in order to store the glass bottle in the foreign matter storage box 11 without compressing it, it does not output a command to the compression device control unit 35 and moves the first sorting lever 17 to move the glass bottle A necessary command is output to the sorting lever control unit 37 to set the glass bottle to a position that leads to the foreign matter storage box 1'1.As a result, the inserted glass bottles are stored in the foreign matter storage box 11 without being compressed. .

Therefore, according to this embodiment, even if foreign objects other than empty cans are thrown in, they are not led to the compression roller side, thereby preventing the compression roller from being damaged or the compression motor from malfunctioning. Even if metallic foreign matter is induced, it is removed into the foreign matter storage box without being compressed, so it is possible to prevent the compression motor and compression roller from being damaged or malfunctioning. Furthermore, by detecting the material of empty cans and storing them separately in the cans, it is possible to improve the efficiency of waste disposal and utilization.

[Effect of the invention 1 As explained above, according to the present invention, when the material of the official object is metal, it is guided to the compressed part, and when the material of the input object is non-metal, it is compressed and the foreign matter is While guiding the input objects to the storage sections, even if the input objects have been guided to the compression section, upon detecting an overload drive that falls into the compression section, the input objects are guided to the foreign object storage section without being compressed. Since the occurrence of abnormalities in the compression section is prevented, empty cans can be compressed with high reliability.
