On the other hand, a movable plate (102) provided so as to be able to move forward and backward
And are arranged. The movable plate (102) faces the fixed plate (101), and a press space (103) is formed between the plates (101) and (102).

A guide passage (107) extends from an empty can input port (not shown) to slightly above the press space (103), and the empty can thus introduced reaches the press space (103). Be guided.

A stopper (106) is provided in the middle of the guide passage (107).
Is provided. As a result, the loaded empty can is temporarily prevented from falling into the press space (103) until the previously loaded empty can is pressed and discharged from the press space (103). Further, an empty can passage sensor (108) is provided slightly below the stopper (106).

The stopper (106) is provided with a stopper motor (109) which is a stopper driving means, so that the stopper (106) can move inside and outside the guide passage (107).

Reference numeral (104) is an empty can receiving plate for temporarily holding the empty can (C) dropped from the stopper (106) in the press space (103).

The empty can held by the empty can receiving plate (104) is pressed by the movement of the movable plate (102), and then the movable plate (102) retreats to drop the pressed empty can from the press space (103). Let

By the way, the movable plate (102) operates on the following principle. That is, as shown in FIG. 12, the eccentric cam fixed at the center position to the rotary shaft (4) of the press motor (3).
(2) is provided. A support shaft (5) is fixed at a position off the center of the eccentric cam (2). The support shaft (5) is connected to the drive shaft (7) via a bearing (6), and the drive shaft (7) is fixed to the movable plate (102).

Then, when the press motor (3) is driven,
As a result, the eccentric cam (2) rotates and the movable plate (10

After the empty can is pressed, that is, when the movable plate (102) is retracted, the movable putt (102) moves to the micro switch (1
After passing over 10), the switch lever comes into contact with this, the micro switch (110) is turned off, the press motor (3) stops, and the stopper motor (109)
Turns on (see FIG. 13). As a result, the press motor (3) that moves the movable plate (102) is braked, the movable plate (102) stops at a predetermined position, and substantially the entire stopper (106) is located outside the guide passageway (107). Then, the empty can to be pressed next, which has been blocked by the stopper (106), falls onto the empty can receiving plate (104) and is placed in the press space (103). At this time, the empty can passage sensor (108) detects the passage of the empty can, and the plate drive signal (Q) is issued to the press motor (3) by this, and the movable plate (102) moves to the fixed plate ( 101) Start moving to the side. Then, after the empty can press, the movable plate (102) retreats.

[0012]

In the empty can collecting machine having the above structure, it takes a very long time to process one empty can. A method of increasing the moving speed of the movable plate (102) may be considered in order to shorten the processing time, but it may cause a failure and is not a very good method.

[Object of the Invention] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an empty can collecting machine which can significantly reduce the processing time of empty cans.

[0014]

According to a first aspect of the present invention, there is provided an empty can collecting machine, a fixed plate, a movable plate which faces the fixed plate and which moves back and forth with respect to the fixed plate, and a movable plate for moving the movable plate. Plate driving means, an empty can guide passage extending from the empty can inlet to a position slightly above the plates, a stopper for temporarily preventing passage of an empty can in the middle of the empty can guide passage, and the stopper In the empty can collecting machine, a stopper drive means for moving the opening and closing directions and a stop command means for stopping the plate driving means with passage of the movable plate after the empty can press is performed. Detecting means for outputting a command to temporarily move the stopper driving means in the opening direction with passage of the movable plate after can pressing, the stop command means and the fixed means. In which it provided between the rate.

According to another aspect of the present invention, there is provided an empty can collecting machine, a fixed plate, a movable plate which faces the fixed plate and which moves back and forth with respect to the fixed plate, a plate driving means for moving the movable plate, and an empty space. An empty can guide passage extending from the can input port to a position slightly above the plates, a stopper that temporarily blocks passage of an empty can in the middle of the empty can guide passage, and an opening direction and a closing direction of the stopper. In an empty can collection machine comprising stopper driving means for moving the movable plate and stop command means for switching the output signal as the movable plate passes, the output signal is switched as the movable plate passes. A detection means is provided between the stop command means and the fixed plate, and the stopper drive means, each of the stop command means and the midway detection means are turned off. Circuit or an AND circuit, and connects the plate driving means, the stop command means, and the intermediate detection means to the AND circuit when the OR circuit is selected, and when the AND circuit is selected. Is connected via an OR circuit.

[0016]

In the empty can collecting machine according to the first aspect, the movable plate that retreats after pressing the empty can reaches the intermediate detection means before reaching the stop command means. When reaching the detection means on the way, the stopper drive means temporarily operates in the opening direction, whereby the stopper is opened and the empty can to be pressed next is arranged in the press space. Since the empty can is dropped before the movable plate reaches the stop command means, the time for processing the empty can is shortened accordingly.

Further, according to the empty can collecting machine of the second aspect, a signal (ON command signal) output from the stop commanding means for driving the stopper driving means and stopping the plate driving means is provided. , OFF command signal) and signals (ON command signal, OFF command signal) output from the midway detection means.

That is, the combinations of the respective signals from the midway detection means and the stop command means, which can be considered depending on the position of the movable plate provided so as to be able to move forward and backward, are ON and ON, ON and OFF, and OFF. OFF
There are three types, and if this is processed by an OR circuit (OR circuit), it will be ON, ON, OFF, and AND
ON, OF if processed by a circuit (AND circuit)
F, OFF.

Then, it is programmed so that the stopper driving means is driven and the plate driving means is stopped depending on the difference between the processing results of the two.

With this, it becomes possible to drive the stopper drive means at a stage when the movable plate reaches the midway detection means, that is, before reaching the stop command means (it is possible to drop an empty can to be pressed next). Therefore, the processing time for empty cans can be shortened accordingly.

If the stopper driving means is driven and the plate driving means is stopped by a combination of a signal output from the stop command means and a signal output from the midway detection means, the stop command means is obtained. It is possible to use the midway detection means having the same standard and the same shape.

That is, the plate drive means is stopped by a signal from the stop command means as in claim 1,
If the stopper drive means is driven by a signal from the midway detection means, when assembling the empty can collection machine, it is necessary to pay close attention so that the wiring is not staggered, or to comply with another standard. It is necessary to prevent erroneous wiring as much as possible by using the stop command means and the midway detection means. If the midway detection means is mistakenly connected to the plate drive means and the stop command means is mistakenly connected to the stopper drive means, the movable plate will stop midway in the stroke range.

However, according to the second aspect,
Since the stop command means is connected to both the stopper drive means and the plate drive means, and the midway detection means is simultaneously connected to the stopper drive means and the plate drive means, in other words, for each stop command means or during the midway detection means. Since it is not necessary to perform wiring for each, it is possible to configure both with the same standard and the same shape.

[0024]

According to the empty can collecting machine of claims 1 and 2, the processing time of empty cans can be greatly shortened.

According to the empty can collecting machine of claim 2,
At the time of assembly, there is no need to wire for each stop command means or for each midway detection means, so that there is no fear of erroneous wiring, and both can be easily configured with the same standard and the same shape.

Is extended. The movable plate (32) is the fixed plate (3
The forward / backward movement is performed with respect to 0) in a direction in which the drive shaft (7) extends (hereinafter, this direction is referred to as “front-back direction”).

The basic principle of moving the movable plate (32) is the same as the principle explained in the prior art, and is omitted here.

Reference numeral (50) is an empty can guide passage, which extends from the empty can inlet to slightly above the press space (36). The introduced empty can reaches the press space (36) through the empty can guide passage (50). In order to prevent multiple empty cans from reaching the press space (36), empty can guide passages (5
0) is provided with a stopper (52) that can be opened and closed.
That is, while one empty can is being processed in the press space (36), other empty cans are made to stand by by this stopper (52), and after the processing is completed, the stopper (52) moves in the opening direction. , The empty can that had been waiting falls toward the press space (36). The stopper (52) is the stopper motor (5
It moves by 4).

An empty can passing sensor (56) is provided slightly below the stopper (52) to detect an empty can passing through the stopper (52).

Reference numeral (38) is an empty can receiving plate. The empty can receiving plate (38) is arranged so as to close the press space (36) from below, and is used to temporarily hold the inserted empty can in the press space (36) before pressing. is there.

The empty canister receiving plate (38) has, on the side of the movable plate (32), two mounting legs (38a) which sandwich the movable plate (32). A fixed support shaft (42) extending in the left-right direction is arranged behind the movable plate (32), and the mounting leg (38a) is pivotally supported by the fixed support shaft (42) at its end. . As a result, the empty can receiving plate (38) is rotatable about the pivotal support (X).
The empty can receiving plate (38) is normally biased by a spring (not shown) in the direction of the arrow (solid line) in FIG. There is.

The empty can receiving plate (38) also serves as a weight sensor. That is, when an empty can having a certain weight or more, such as a can filled with pebbles or contents remaining therein, is loaded, the empty can receiving plate (38) is urged. The spring mechanically loses and the empty can receiving plate (38) pivots largely around the pivot (X), whereby the empty can falls from the press space (36) without being pressed. As described above, since the empty can receiving plate (38) is biased by the spring, the empty can receiving plate (38) after the empty can has dropped is in its original position (the position shown in the figure). Return to.

Reference numeral (60) indicates a stop micro switch which is stop command means. Each time the movable plate (32) moves over the stop micro switch (60), the movable plate (32) and the switch lever of the stop micro switch (60) come into contact with each other, and the stop micro switch (60) is reached.

This will be described with reference to FIG. Empty can collection machine with the above structure (11)
In, the empty can (C) is arranged in the press space (36), and the empty can (C ′) is waiting in the empty can guide passage (50) by the stopper (52) (FIG. 3). reference).

In this state, the movable plate (32) advances toward the fixed plate (30), and accordingly the empty can (C) begins to be pressed (see FIG. 4).

The movable plate (32) is a fixed plate (30)
In the state of being closest to, the empty can (C) is no longer completely pressed (see FIG. 5).

After that, the movable plate (32) retreats, but with this, the pressed empty cans fall from the press space (36), and a predetermined position (2
It is collected in 1) or (22) (see Figure 6 and Figure 1).

While the movable plate (32) is retreating, the movable plate (32) reaches above the microswitch (62) on the way (see FIG. 7). When the movable plate (32) passes over the micro switch (62) on the way, as described above, the movable plate (32) and the micro switch (62) on the way.
The switch lever contacts the switch and the micro switch (62) is turned on (see FIG. 9). As a result, the stopper motor (54) starts to drive and the stopper motor (5
4) moves the stopper (52) in the opening direction. Therefore,
The empty can (C ') that had been waiting dropped, and this empty can (C')
Head for the press space (36). The stopper (54) is programmed so as to immediately return to the original position (the position shown in FIG. 3) after dropping the empty can.

At that time, the movable plate (32)
Has reached above the stop microswitch (60) (Fig. 8
reference). When the movable plate (32) passes over the stop micro switch (60), the movable plate (32) and the switch lever of the stop micro switch (60) come into contact with each other as described above, and the stop micro switch (60 ) Switches to OFF (see FIG. 9). As a result, the press motor (3) is braked and the movable plate (32) is stopped.

The empty can (C ') passes through the empty can passage sensor (56) while falling. The empty can passage sensor (56) detects this and sends a drive signal (Q) to the press motor (3). As a result, the press motor (3) starts to be driven again, the movable plate (32) advances toward the fixed plate (30), and the empty can (C ′) is pressed.

As described above, in the empty can collecting machine (11) of the present invention, the movable plate (32) that retreats after pressing the empty can is in the middle of reaching the stop micro switch (60). It will reach the microswitch (62).
Then, as described above, the micro switch (62) on the way.
When the stopper (52) is moved to the opening direction so that the empty can to be pressed next is placed in the press space (36), the movable plate (32) stops the drop of the empty can. Since it can be done before reaching the switch (60), the processing time for empty cans is shortened accordingly.

In this embodiment, the micro switch is used as the stop command means and the midway detection means, but a sensor (such as an infrared sensor) may be used instead.

As will be described in the following embodiments, the signals (ON command signal, OFF command signal) output from the stop micro switch (60) are used to drive the stopper motor (54) and stop the press motor (3). ) And a signal output from the micro switch (62) on the way (ON command signal, OFF

[0050]

[Table 1]

In the present embodiment, as shown in FIG. 11, the stopper motor (54), the stop micro switch (60) and the intermediate micro switch (62) are ORed together.
The circuit is connected via a circuit (70, an OR circuit), and the press motor (3) and each of the stop micro switch (60) and the intermediate micro switch (62) are connected via an AND circuit (72, an AND circuit). Connected. As a result, the ON and OFF signals emitted from the stop micro switch (60) and the micro switch (62) on the way are processed by the OR circuit (70),
The processed information is input to the stopper motor (54).
Further, ON and OFF signals emitted from the stop micro switch (60) and the micro switch (62) on the way are processed by the AND circuit (72), and the processed information is input to the press motor (3).

If the ON-OFF information of [Table 1] is processed by the OR circuit (70) and the AND circuit (72), it becomes as shown in [Table 2] below.

[0053]

[Table 2]

That is, the movable plate (32) reaches "C" from "A" through "B", and again passes through "B" and then "A".
When returning to, the signals from the stop microswitch (60) and the midway microswitch (62) are applied to the OR circuit (70) and the AN.
When processed by the D circuit (72), the results are shown in [Table 3] below.

[0055]

[Table 3]

Therefore, in the OR circuit (70), the stopper motor (54) is driven when the processed information changes from OFF to ON, and in the AND circuit (72), the processed information changes from OFF to ON. If the press motor (3) is programmed to stop when it changes to, the movable plate (32) stops and the micro switch (6)
The stopper motor (54) can be driven before reaching 0). That is, the empty can to be pressed next can be dropped from the stopper (52). Therefore, the processing time for empty cans is shortened accordingly. Further, when this embodiment is adopted, the stop micro switch (60) is connected to the stopper motor (54) and the press motor (3) at the time of assembling the empty can collecting machine, and the micro switch (62) is midway.
Since it is also connected to the stopper motor (54) and the press motor (3) at the same time, in other words, it is not necessary to wire each stop micro switch (60) or each micro switch (62) in the middle. Therefore, there is no fear of erroneous wiring, and both can be easily configured with the same standard and the same shape.
