Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty container collecting and processing machine for processing and collecting empty containers such as empty cans and empty bottles.

[0002]

2. Description of the Related Art Empty container collecting and processing machines collect empty containers such as beverage cans, empty bottles, empty plastic bottles and the like by performing volume reduction processing such as compression if necessary, and in some cases, exchange them for cash. It is also a machine that has a function of issuing and issuing (depositing) tickets.

FIG. 4 shows the structure of an example of a conventional empty container recovery processor. The loaded empty containers are determined by information from a detection sensor (hereinafter, referred to as DSn), a detection switch (hereinafter, referred to as DSw), and a barcode reader, are sorted by the sorting device 2, and are collected after the volume reduction processing. Or collected or returned as is. In this example, the volume of the metal can is reduced by the press device and collected.

Hereinafter, the configuration and operation of the empty container collecting and processing machine will be described in more detail. Above the front door of the empty container collection processor, there is an empty container input port 11, and the input port
In the vicinity of 11, an inlet lock solenoid (hereinafter, the solenoid is referred to as Sl) 12, an inlet open DSw13o, and an inlet close D
Sw13c and are arranged.

[0005] The inlet 11 can be opened when the empty container recovery processor is in operation and is waiting for empty containers to be inserted. When an empty container is thrown in or in case of trouble,
Alternatively, during non-operation, the inlet 11 is locked by the inlet lock Sl12 and does not open. The open / close state of the inlet 11 is detected and confirmed by the inlet opening DSw13o and the inlet closing DSw13c.

In the vicinity of the charging port inside the charging port 11, there is a charging port.
A container DSn14 for detecting that an empty container has been inserted from 11 is disposed, and when an empty container is inserted, a detection signal is transmitted.

In the middle of the passage of the empty container inside the charging port 11, there are arranged a material iron DSn15F, a material aluminum DSn15A, and a weight DSw16 for detecting the material and weight of the empty container introduced from the charging port 11. And immediately after the weight DSw16,
A shutter driven by shutter opening / closing Sl17 for temporarily holding an empty container is provided. Weight DSw16 is
In order to directly detect the deflection of the weight detection plate which is bent by receiving the weight of the empty container, it is disposed immediately below the weight detection plate.

When an empty container is inserted, the shutter is closed, and the empty container is stopped and retained at the front of the shutter, and its material and weight are detected by the material DSn15F and the weight DSw16. When the detection of the material and the weight is completed, the shutter is opened by the shutter opening and closing Sl17, and the empty container is sent to the sorting device 2. In the case of this empty container collection processing device, the empty containers whose material is determined are iron cans, aluminum cans and other containers, and the weight DSw16 is
An empty container with a weight exceeding the specified value is detected, and a certain amount of content remains, or the inside is partially or entirely clumped, or the content is clogged. Sort containers and the like as they are.

It should be noted that, as a precautionary note, in the description of this specification, a container that is not an empty container (a container in which contents are still clogged) is treated as an empty container having a weight exceeding a predetermined value. They are unified with empty containers.

It is the bar code reading information of the empty container that determines whether or not the empty container that has been put in is an object to be collected. Therefore, the sorting device 2 has a rotating mechanism for empty containers and two barcode readers for rotating the empty containers and reading the barcode before sorting the empty containers.
29l and 29r are arranged. The rotation mechanism includes a container rotation motor (hereinafter, the motor is referred to as M) 21 and two rollers driven by the motor.

The empty container that has passed through the shutter is held and rotated by two rollers rotated by a container rotation M21, and the barcode is read by a barcode reader (left) 19l and a barcode reader (right) 19r. Can be The two bar code readers are arranged because the empty container collection processing device is designed to have a structure in which empty containers are thrown sideways. Since some empty containers have different lengths, two barcode readers 19l and 19l are used.
By arranging r side by side, the barcode reading rate is increased. The information read from the barcode is the type of the contents, the name of the manufacturer, the volume of the contents, the selling price, and the like, and the material of the container is not recorded in the barcode.

The empty containers for which the reading of the barcode has been completed are sorted by the sorting device 2 based on various information obtained so far. The sorting device 2 is based on the aforementioned 2
A mechanism for dropping empty containers from the two rollers, a method for reducing the volume of falling empty containers based on various information obtained so far, and a method for collecting empty containers as they are,
And a sorting mechanism for sorting the items to be returned.

The drop mechanism is driven by the container drop M26, moves one of the rollers holding the empty container, widens the interval between the two rollers, and drops the empty container held.
Whether the roller is at the position for holding the empty container or at the position for dropping the container is determined by the container drop closing DSw28c and the container drop opening D
Confirmed by Sw28o.

The sorting mechanism is driven by the sorting M22, and sorts empty containers by directing the sorting flapper in a predetermined direction. The sorting flapper consists of two parallel plates, each plate having its upper part as a fulcrum,
Change the direction in the same direction according to the destination.

The operation of sorting empty containers and subsequent operations will be described below. If the barcode of the empty container cannot be read or is not the predetermined one, the empty container is returned. In this case, the sorting flapper is swung to the left, and it is confirmed at the sorting position DSw25r that the sorting flapper is on the return side. Then, the container drop M26 is driven, and the two rollers holding the empty container are driven. Increase the interval and drop empty containers. The dropped empty container is guided by the flapper to the passage to the return opening 54, held on the return opening bottom plate 52, and returned to the person who put the empty container. If the empty container is not removed from the return port 54, the return port bottom plate opening / closing M51 is driven to open the return port bottom plate 52 at an appropriate timing until the next empty container is inserted, and the return port bottom plate 52 is opened. The empty container remaining on the top is dropped into the collection container 41f such as a bottle. Opening of the return opening bottom plate 52 is confirmed by the return opening bottom plate opening / closing DSw 53. After that, return port bottom plate 52
Is closed again, and that the closure is closed
Confirmed by 53.

If the bar code is a predetermined one, a metal can, and the weight is within a predetermined value, the sorting flapper is swung to the right, and the sorting flapper is moved to the press side which is a volume reduction processing apparatus. After it is confirmed at the distribution position DSw25p that there is an empty container, the held empty container is dropped into the press device and compressed and reduced in volume by the piston driven by the press M31 in the same manner as described above. The press device is provided with a top dead center DSw32u for detecting that the piston has reached the top dead center and a bottom dead center DSw32l for detecting that the piston has reached the bottom dead center. Move to check if the empty container has been successfully compressed. The reduced empty container is guided to the movable chute driven by the sorting M33 based on the material detection result described above, and the aluminum can collection container 41A or the iron can collection container 41F.
Will be collected. Whether the shooter is on the aluminum can collection container 41A side or the iron can collection container 41F side is determined by the shooter position D.
Confirmed by Sw35A and 35F.

If the bar code is a predetermined one and not a metal can, or if the bar code is a predetermined one and is a metal can and the weight exceeds a predetermined value, the sorting flapper is activated. After it is confirmed at the distribution position DSW25f that the distribution flapper is directed downward and the distribution flapper is directed downward, the held empty container is dropped and collected in the collection container 41f such as a bottle in the same manner as described above.

In any case, the container drop M26
After the empty container is dropped, the rotation is continued, and the roller is returned to a position where the next empty container to be charged is held and rotated. When returning to this state is detected by the container drop closing DSw28c, the container drop M26 is stopped.

The three collection containers 41A, 41F and 41f
Are provided with full collection containers DSn42A, 42F and 42f for detecting that the collection container is full (FIG. 4 shows the full collection container DSn42A for the aluminum can collection container). Absent).

[0020]

As is apparent from the above description, the conventional empty container collecting and processing machine has the following problems.

1) Since all of the empty containers that have been introduced are once taken into the inside, a sorting mechanism and a return mechanism for returning uncollected items are required, and the apparatus is accordingly complicated.

2) Many (five in FIG. 4) motors for driving are used, and many (12 in FIG. 4) detection switches for position detection are used. for that reason,
Cost increases and reliability decreases.

3) Since the empty container is thrown in sideways and rolled and moved, if contents etc. remain in the empty container, it leaks into the device and is scattered, contaminating the inside of the device. However, it may cause a malfunction.

An object of the present invention is to solve these problems and to provide an empty container collecting and processing apparatus which is simplified in structure, has a small number of parts, is inexpensive and has excellent reliability.

[0025]

In order to achieve the above object, a bar code, material and weight of a vacant container such as a filled beverage are detected, and the vacant container is processed based on the information. An empty container collection processing machine that determines whether or not it is a target product, and if the empty container is a product to be processed, performs predetermined processing and collects it. In the above, based on the input information of the empty container input port also serving as the return port of the empty container, the bar code reading means of the input empty container arranged close to the input port, and the read information of the bar code reading means A shutter mechanism is provided in the middle of the passage of the empty container, which opens and closes whether or not the empty container is taken into the inside of the apparatus. , The shutter mechanism is closed Leave is a, thrown-in empty containers is not taken into the apparatus (the invention of claim 1).

When the charged empty container is not an object to be collected or cannot be discriminated as an object to be collected, the shutter mechanism is kept closed and the inserted empty container is not taken in. A mechanism for returning the container is not required.

[0027] In the first aspect of the present invention, the input port is
The empty container is formed in a shape that can be inserted only when the empty container is inserted in the length direction, and the conveyance path of the empty container is formed in a shape in which the empty container moves in the inserted length direction. 2).

When the empty container is inserted in the length direction, the direction of the bar code at the time of insertion does not change much after the insertion. The bar code can be read with high probability without rotating the empty container, and the rotation mechanism of the empty container can be eliminated. Furthermore, since the movement posture at the time of transportation does not change, if the feeding with the drinking mouth is specified, the drinking mouth is always at the top, and the remaining liquid hardly leaks,
Troubles such as malfunction due to residual liquid leakage do not occur.
In most empty containers, the barcode is located below the container (the position opposite to the spout in the length direction), so if the empty container is inserted so that the barcode can be read, the spout is inevitable. And the remaining liquid does not leak.

According to the first aspect of the present invention, the inserted empty containers can be freely inserted and removed from the input port until the barcode reading is completed. Therefore, an article to be processed (for example, a container to be deposited) is inserted from the input port, the barcode is read, and information indicating that the object is to be deposited is sent. It becomes possible to throw in empty containers and deposit them. The invention of claim 3 and the invention of claim 4 described below prevent the execution of processing such as deposit for such misconduct, and prevent improper processing of a vacant container that has been incorrectly inserted. This is an invention to avoid adding (eg, press processing of a bottle).

According to the first aspect of the present invention, two container detection sensors are provided in front of and behind the shutter of the shutter mechanism at intervals so that one empty container can be simultaneously detected. If the container detection sensor placed in front of the shutter goes into a non-detection state after the container detection sensor placed in It is determined that the detection state is not the normal insertion of empty containers, and the process is not executed (the invention of claim 3).

When the above-mentioned misconduct is executed,
Since the container into which the barcode has been read out is withdrawn, the detection signal of the container detection sensor in front of the shutter is interrupted before another next empty container is inserted. Therefore, in the case of cheating, the detection signals of the two container detection sensors disposed before and after the shutter do not overlap. Therefore, if the two container detection sensors arranged before and after the shutter are arranged at an interval at which one empty container can be detected at the same time, it is possible to determine whether it is normal insertion or improper operation.

According to the first aspect of the present invention, two container detection sensors are provided before and after the shutter of the shutter mechanism at intervals so that one empty container can be simultaneously detected. When the container detection sensor placed in front of the shutter goes into a non-detection state after the container detection sensor placed before The shutter is closed immediately after it is determined that the normal empty container is not detected and the container detection sensor disposed in front of the shutter is in the non-detection state (the invention of claim 4). .

Also in the case of the present invention, the determination of impropriety is exactly the same as that of the third aspect. The difference is that in the case of the third aspect of the invention, empty containers that have been inserted later in the case of misconduct are collected, but no processing is performed, whereas in the case of the fourth aspect of the invention, That is, the empty container that has been charged later is not taken into the apparatus (naturally, no processing is executed).

[0034]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The feature of the empty container collecting and processing machine according to the present invention is that, before taking in empty containers into the apparatus, it is determined whether or not an object to be collected is an object to be collected or an object not to be collected. Inappropriate acts such as returning the non-collected items without taking them in, returning the empty containers at the same position in the length direction, and replacing the empty containers (see below) Will be explained in detail)
No deposit and processing are executed.

An embodiment of the empty container collecting and processing apparatus according to the present invention will be described below with reference to examples. It is to be noted that the same reference numerals are used for portions having the same functions as the conventional technology.
FIG. 1 shows the configuration of an embodiment of an empty container recovery processor according to the present invention, and FIG. 2 shows the configuration of an empty container loading / returning unit of the embodiment.

In the empty container charging / returning section of this embodiment,
An input port 11a, a shutter mechanism that holds the input empty container 6 and is opened when the empty container 6 is taken into the apparatus, and an input port that is disposed in front of the shutter mechanism and detects the presence or absence of the empty container 6. A side container DSn14a, a metal DSn15M for detecting the material of the empty container 6, and a barcode reader 19 as barcode reading means are provided.

The inlet 11a is formed in a shape that can be inserted only when the empty container 6 is inserted in the longitudinal direction, for example, a square or a circle, and the empty container 6 is inserted obliquely downward. It is inclined to. The passage for moving the empty container from the input port 11a to the sorting device 2a is formed in a shape such that the empty container always moves in the direction at the time of insertion, for example, a rectangular passage having a width slightly wider than the maximum container diameter that can be accepted. The empty containers do not roll sideways.

The shutter mechanism comprises a shutter opening / closing SL (solenoid) 17, a pair of shutter plates 72 opened left and right by the shutter opening / closing SL17, and a shutter closing DSw18 for detecting that the shutter is closed. .

The empty container 6 to be charged from the charging port 11a
The barcode is inserted obliquely in the lengthwise direction with the bar code facing upward and the spout facing upward. The loaded empty container 6 is firstly detected by the container DSn14a, and then held by a shutter plate 72 of a shutter mechanism for controlling whether or not the empty container 6 is to be taken into the apparatus. The bar code is read, and at the same time, whether or not the container is a metal container is detected by the metal DSn15M. Based on the read barcode information, it is determined whether to take the empty container 6 into the apparatus or return it on the spot. When the empty container 6 is taken in, the shutter plate 72 is opened, and when returned, the shutter plate 72 is closed. The return will be notified by a display or the like while being left. When the empty container recovery processor is in operation, the shutter plate 72 is opened only when taking in the empty container 6, and is closed at other times. For some reason, such as a foreign object being caught in the shutter plate 72,
When the is not closed, the empty container collecting processor is stopped, and the empty container 6 is not collected. Empty container 6
Is returned when the product is not a collection target product and when the barcode cannot be read. It is displayed in the vicinity of the insertion port 11a that the bar code is to be inserted with the bar code facing upward, the insertion is to be performed with the drinking side facing upward, and the return product is to be picked up.

The empty container 6 that passes through the shutter plate 72 and is taken into the apparatus is first detected by the sorting-side container DSn14b immediately after passing through the shutter plate 72. The distribution-side container DSn14b is arranged at a distance that can simultaneously detect the same empty container as the above-mentioned inlet-side container DSn14a. The timing of the detection signal of the sorting-side container DSn14b arranged in this way is made to correspond to the timing of the detection signal of the input-side container DSn14a, and it is determined whether an empty container has been normally inserted or an illegal operation has been performed. Is done.

The fraudulent acts referred to here are the following acts. In the case of the empty container charging / returning section as described above, the empty container 6 can be freely inserted and removed from the input port 11a until the inserted empty container 6 is taken into the shutter plate 72. Therefore, insert the container to be deposited from the input port 11a, read the barcode and send the information that the object is to be deposited, then quickly remove this container and insert another empty container that is not to be deposited. For example, it is possible to deposit in an empty container that is not a deposit target. Such an act is called fraud.

Here, with reference to FIG.
A description will be given of the determination as to whether the act is an act. Fig. 3 shows the inlet side

You. FIG. 3 corresponds to the case where a metal can is put in.

First, a description will be given of a case of normal input. When the metal can to be collected is inserted from the input port 11a, the metal can is detected by the input side container DSn14a from the time of input (T ₁ ) until the shutter plate 72 is opened and taken in (T ₂ ). (signal S _14a), is detected in approximately the same time the metal DSn15M (signal S _15M). During this time, the bar code is read (signal S ₁₉ ), the metal can is determined to be an object to be collected, the shutter opening / closing Sl ₁₇ is energized (current I ₁₇ ), and the shutter plate 72 is opened (signal S _18). ), turned metal cans is moved into the device, it is detected by the distribution side container DSn14b (S _14b). Since both the container DSn14a and 14b are disposed at a position capable of detecting the same vessel at the same time, as indicated by broken line arrow, before the signal S _14a is OFF (non-detection state), the detection signal of the signal S _14a And the detection signal of the signal _S14b have an overlapping portion. By confirming this overlap, it can be determined that the input is normal.

Next, a case of fraud will be described. When the metal can to be collected is first loaded, the signal S _14a and the signal S
_15M , the signal S ₁₉ , the current I ₁₇ and the signal S ₁₈ start in the same manner as in normal charging, but the metal can of the object to be collected which is initially supplied is after the bar code is read (T ₃ ).
Is taken out and another container is put in, so the signal S _14a
And the detection signal of the signal _{S15M stops} once and is detected again. The detection signal of the signal _S14b is detected only when the container inserted later passes through the shutter plate 72. Therefore, in the case of fraud, the signal S _14a and the signal S _15M
No detection signal is detected in the signal S _{14 b} while the first detection signal is being detected. Thus, the signal S
Before the first detection signal _14a is interrupted, when the the detection signal of the detection signal and the signal S _14b of the signal S _14a not detected overlap is possible to judge that empty containers initially charged it has been removed Therefore, this case is determined to be fraudulent.

In the case of FIG. 3 (b), the empty container, which has been replaced and charged, passes through the shutter plate 72 and enters the apparatus, so that the detection signal is not only the signal _S14a and the signal _S15M but also the signal S15M. It also appears in _14b . Signal S _14a and signal S _15M
The reason why the detection signal of the signal S _{14 b} is longer than the detection signal of
This is because they are temporarily staying for sorting. FIG.
In case (c), when the detection signal to the signal S _14a is not detected (T _3), by the detection signal to the signal S _14b is not detected so far, the on (signal S _14a The first detection signal) is determined to be fraudulent, and the shutter plate 72 is immediately closed. As a result, empty container supplied from a later order is stopped by the shutter plate 72, the signal S _14b does not appear detection signal.

[0046] As apparent from the above description, the determination of whether a normal-on, judge whether the detection signal of the first detection signal and the signal S _14b of the signal S _14a is detected redundantly it can.

FIG. 3 is a time chart in the case of a metal can. In the case of a container other than a metal can, the same applies to other cases except that no detection signal is detected as the signal _S15M .

It is determined whether the metal container has been normally inserted or a fraudulent operation. The empty container discriminated whether the material of the metal container is iron or aluminum by the material aluminum DSn15A is held by the stopper / flapper at the standby position. The weight is temporarily stopped, and when the weight exceeds a predetermined weight, whether or not the weight exceeds a predetermined weight is detected by a weight detecting means including an actuator that operates when the weight exceeds a predetermined weight and a weight DSw16 that detects the operation of the actuator. Information on whether or not it was successfully inserted,
The sorting device 2 reduces the volume of the empty container based on the information as to whether or not the container is a metal container using the metal DSn15M, the information as to whether it is iron or aluminum using the material aluminum DSn15A, and the information as to whether or not the weight is within a predetermined weight by the weight detecting means. Distribute to those that do not undergo volume reduction processing. Items that are to be volume-reduced are normally charged metal cans within a specified weight, and those that are not to be volume-decreased are those that have been thrown in by wrongdoing, objects other than metal cans such as glass bottles, and the specified weight. It is a metal can that is over.

The sorting device 2a is a sorting device that can be rotated forward and reverse.
It comprises a stopper 22a and a stopper / flapper driven thereby, and sorts empty containers according to the rotation direction of the sorting M22a. Those not subjected to volume reduction processing are directly collected in a collection container 41f such as a bottle, and those subjected to volume reduction processing are sent to a pressing device which is a volume reduction processing device, compressed, and then guided to a movable chute to be transferred to an aluminum chute. It is collected in the can collection container 41A or the iron can collection container 41F.

The press device is driven by a press M31 and has a top dead center DSw32u for detecting that the piston has reached the top dead center and a bottom dead center DSw32l for detecting that the piston has reached the bottom dead center. It is checked by these whether the empty container was pressed normally. The position of the movable shooter (the shooter in FIG. 1) 34 is controlled by the sorting M33 controlled by the detection information of the material aluminum DSn15A, and whether the shooter 34 is on the aluminum can collection container 41A side,
Whether it is the iron can collection container 41F side is determined by the shooter position DSw35A.
And confirmed by 35F.

Each of the three collection containers 41A, 41F and 41f is provided with a collection container full DSn 42A, 42F and 42f for detecting that the collection container is full (FIG. 1). A full collection container DSn42A for an aluminum can collection container is not shown in FIG.

As is clear from the above description, the embodiment of the empty container collecting and processing apparatus according to the present invention returns items not to be collected and those for which the barcode cannot be read without taking them into the empty container collecting and processing apparatus. It does not require a return path or a sorting mechanism.Furthermore, empty containers are loaded and transported in the lengthwise direction with the barcode facing up and the drinking spout facing up. No rotation mechanism is required, and leakage of residual liquid is very small. Therefore, the number of motors and the number of position detection Sws are significantly reduced, and only one bar code reader is required, which is advantageous in terms of cost and greatly improved reliability.

In the above-described embodiment, the case where the volume reduction processing is performed on the metal can by the pressing device has been described. However, the case where the volume reduction processing is performed on the pet potl can be replaced. You can also.

[0054]

According to the present invention, the barcode, material and weight of an empty container such as a charged beverage are detected, and it is determined whether or not the empty container is an object to be processed based on the information. If the empty container is an item to be processed, it will be collected after performing a predetermined process, and if it is not an item to be processed, it will be collected unprocessed. An input port of an empty container that also serves as a barcode reading means for an input empty container arranged in close proximity to the input port,
A shutter mechanism provided in the middle of an empty container passage, which performs an opening / closing operation to determine whether or not to take the empty container into the apparatus based on the read information of the bar code reading means; If the empty container cannot be determined to be an item to be collected, the shutter mechanism is kept closed and the inserted empty container is not taken into the apparatus, so that a mechanism for returning the empty container is unnecessary. Becomes
Therefore, it is possible to provide an empty container collecting and processing machine having a simplified structure, a small number of parts, a low cost, and excellent reliability (the invention of claim 1).

[0055] In the invention of claim 1, the input port is
The empty container is formed in a shape that can be inserted only when the empty container is inserted in the length direction, and the conveyance path of the empty container is formed in a shape in which the empty container moves in the inserted longitudinal direction. When empty containers are loaded in the length direction, the direction of the barcode at the time of loading does not change much after loading, so if you specify the direction of the barcode at the time of loading, The bar code can be read with high probability without rotating, and the rotating mechanism of the empty container can be eliminated. Furthermore, since the moving posture during transport does not change, if the feeding with the drinking spout is specified, the drinking spout is always up and almost no residual liquid leaks, and trouble such as malfunction due to residual liquid leakage will occur. No longer occurs. In most empty containers, the barcode is located below the container (the position opposite to the spout in the length direction), so if the empty container is inserted so that the barcode can be read, the spout is inevitable. And the remaining liquid does not leak. Therefore,
It is possible to provide an empty container collecting and processing machine having a simpler structure, a smaller number of parts, a lower cost, and more excellent reliability (the invention of claim 2).

According to the first aspect of the present invention, two container detection sensors are provided in front of and behind the shutter of the shutter mechanism at intervals so that one empty container can be simultaneously detected. When the container detection sensor placed in front of the shutter goes into a non-detection state after the container detection sensor placed before It is determined that the detection state is not a normal empty container insertion, and the processing is not executed. Therefore, a container to be processed such as a deposit is inserted from the insertion port, and the barcode is read to be processed. Send the information, then quickly remove this container and put in another empty container that is not to be processed and execute the process against fraudulent acts that try to execute the process Doo is avoided (the invention of claim 3).

Further, according to the first aspect of the present invention, two container detection sensors are provided before and after the shutter of the shutter mechanism at intervals so that one empty container can be simultaneously detected. When the container detection sensor placed in front of the shutter goes into a non-detection state after the container detection sensor placed before It is determined that the detection state is not a normal empty container insertion, and the shutter is immediately closed after the container detection sensor arranged in front of the shutter is in the non-detection state, so that the container is improperly inserted. The empty container is not taken into the inside of the apparatus, and the processing is not executed for the above-mentioned misconduct (claim 4).
