Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatically supplying used tires, which are used when used tires are used as auxiliary fuel for cement firing.

As motorization has accelerated rapidly due to high economic growth, the amount of used tires produced has increased rapidly, and recently, 550,000 tons of used tires are produced annually.

However, the current situation is that most of these huge amounts of used tires are disposed of by piling up, burning in the open, or illegally dumping, which has become a major social problem.

Therefore, in recent years, various efforts have been made to dispose of these types of used tires, and in particular, methods have been developed to use such used tires as a partial substitute for heavy oil fuel, such as as an auxiliary fuel for cement firing. This idea has been attracting attention as being meaningful in terms of the effective use of resources.

By the way, in order to use used tires as auxiliary fuel for cement firing, it is necessary to put the used tires into the kiln main body, and in order not to disturb the temperature conditions inside the kiln main body, it is necessary to It is desirable to keep the input amount of used tires constant.

However, conventionally, used tires have been manually fed into the kiln main body, which has caused problems in that quantitative feeding is difficult and time-consuming.

Unfortunately, used tires come in a variety of sizes, so in order to ensure a quantitative supply, it is necessary to sort used tires into large and small types in advance, and sort them according to their size or weight. This is because the spent tires must be sequentially introduced into the kiln body at appropriate time intervals.

Furthermore, since used tires are usually left outdoors for long periods of time, water often accumulates inside them.

However, if used tires containing water are used directly as auxiliary fuel, there will be a large calorific loss.

Therefore, conventionally, the water inside the used tire has been removed by suctioning it with a pump, forcibly turning over the open part of the tire, or punching, cutting, or pressing the used tire. However, both methods require manual labor and are very time-consuming.

The present invention has been made in view of these circumstances, and aims to make it possible to automatically drain water from used tires and quantitatively feed the water into the kiln body, etc., without relying on human hands. In this way, it is an object of the present invention to provide an automatic method and apparatus for supplying used tires, which can save labor and ensure the simplicity and accuracy of the used tire supply operation.

Now, the process of completing the present invention will be further explained in relation to the prior art.

As mentioned above, methods have been considered to mechanize and automate the process of supplying used tires, which was initially done entirely by hand.

The main points and drawbacks of this technology are as follows.

First, I picked up each of the various used tires that were piled up at random.
The question is how to take it out mechanically.

This may seem simple at first glance, but it is actually a very difficult problem.

In order to solve this problem, a wet method has conventionally been used.

In this method, the used tires are floated on water so that they can be moved with a small amount of force, and then the tires are loosened into pieces and taken out one by one by being placed on a stream of water.

However, this method has the following drawbacks.

(b) A large water tank is required to float a large amount of used tires.

(b) A large amount of sewage from which pollutants such as mud adhering to used tires have been washed out must be treated, but this is not unrelated to the occurrence of pollution.

(c) Tires generally float on water, but perforated tires, cut tires, etc. do not float on water, so a considerable amount of manpower is required to dispose of them.

(b) As mentioned above, water must be drained to prevent heat loss, but once the tire is submerged in water, the amount of water to be drained increases, resulting in additional costs.

The dry drawing device according to the present invention solves these drawbacks.

In other words, this withdrawal device. It was completed by adopting an unconventional dry drawing method devised as a result of trial and error experiments, and has a simple structure that combines an inclined surface, a chain conveyor, and a row of free rollers with a gentle slope. It can solve all the shortcomings.

Next, there was the method of draining water, which at first relied on human labor as mentioned above, which required a great deal of time and money.

Various methods have been tried, such as placing the used tire on rollers and rocking it horizontally, but none of them resulted in sufficient water removal.

The water removal conveyance device according to the present invention solves these problems.

In other words, this water draining and conveying device is capable of draining water while conveying used tires in a fixed direction by giving the gutter-shaped tire guide frame forward and upward movement and backward and downward movement, and can also roughly align the used tires. It is also possible to perform the same tasks, and it is highly effective in automated processes.

Also, although it is important to supply a fixed amount of used tires to a kiln or other baking device, in order to make this possible,
It is important to align the spent tires accurately in the preliminary step.

The alignment device according to the present invention addresses such problems.

In other words, this alignment device combines an opening/closing plate with a tire detector and a roller conveyor to enable more precise alignment than ever before, thereby simplifying the subsequent quantitative delivery process. This effect is achieved.

In other words, the conventional fixed-quantity delivery device measures the weight of the used tire and controls the delivery time of the used tire based on the measured value, which has the disadvantage of a complicated configuration. There is.

However, if the alignment device is used to accurately line up the used tires, an opening/closing plate that has a tire detection end on the tire locking surface and closes in a V-shape to lock the used tires, as described later, can be used. It is also possible to introduce a fixed-quantity delivery device using a simple device that determines the size of a used tire based on its shape and dimensions, making the process flow smoother and easier to automate. You can expect a calming effect.

As is clear from the above explanation, the invention set forth in claim 1 of the present application is capable of converting used tires into
A pair of opening/closing doors closed in a V-shape is locked and placed on standby in a state that can be opened in a double-door style in the downstream direction. The size of the leading used tire is detected based on the contact state between the plurality of tire detection ends and the waiting leading used tire, and based on this detection result, the average tire supply amount per unit time is calculated. The length of the waiting time is determined so as to be constant, and after the waiting time has elapsed, the opening/closing door is opened to send out the first used tire, and the used tires sent out in this way are placed in a predetermined amount. In addition to adopting a quantitative feeding process in which the liquid is fed into the supply position, a dry drawing device, water removal conveyance device, and alignment device are installed in the pre-process of this quantitative feeding process, and each of the above-mentioned functions is sequentially provided to each of these devices. An automatic method for automatically supplying used tires that can be used to sequentially pull out used tires that are piled up at random, sufficiently drain water, and supply them smoothly and accurately in quantity to a predetermined supply location. The inventions set forth in claims 2 to 4 are intended to provide a device necessary for efficiently carrying out this automatic supply method. be.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

This example is for the case where used tires a are used as auxiliary fuel for cement firing.

That is, as shown in FIG. 1, an automatic supply equipment 2 for used tires a is installed near a kiln 1 for firing cement, and this automatic supply equipment 2 supplies used tires a to the kiln main body 1.
Quantitatively supplied to the inlet of a.

The automatic supply equipment 2 includes a hopper 3 that stores a large number of used tires a, a pull-out device 4 that sequentially pulls out the used tires a from the hopper 3, and a pull-out device 4 that sequentially pulls out the used tires a from the hopper 3. a water removal conveyance device 5 that transports the used tires a toward the kiln 1 without shaking them; an alignment device 6 that arranges the used tires a that have passed through the water removal transportation device 5 in a line; A quantitative delivery device 7 that waits the spent tires a at a predetermined position and sequentially sends out the spent tires a that have been put on standby at required time intervals starting from the first one, and the used tires that are sent out from the quantitative delivery device 7. a to a predetermined supply position, that is, the kiln main body 1a.
It consists of a conveying device 8 that guides the conveyor to the entrance of the conveyor.

The hopper 3 is formed by hollowing out a predetermined portion of the ground 9, and is capable of storing therein a large number of used tires a loaded by shovels, trucks, etc.

Further, as shown in FIGS. 2 and 3, the drawing device 4 has a lower end that forms the bottom wall of the hopper 3 and an upper end that forms the bottom wall of the hopper 3.
A sloped surface 12 extending to one end of the opening edge of the hopper 3, and waste materials piled randomly on the sloped surface 12 provided from the other end of the opening edge of the hopper 3 toward the lower end of the sloped surface 12. A multi-row free roller row 11 with a gentle slope that smoothly guides the tire a onto the lower end of the inclined surface 12 by gravity.
. . . and two types of chain conveyors 13 and 14 provided from the lower end face to the upper end of the inclined surface 12, the inner chain conveyor 13 .
The outer chain conveyor 14,14 is driven in the direction of the arrow X by a variable speed motor 15 and by a second variable speed motor 16, respectively.

In addition, the inner chain conveyor 13 has three chains 1.
3a... Rod-shaped attachments 13b... are installed at predetermined intervals in the driving direction, and the outer chain conveyors 14 arranged on both sides of this inner chain conveyor 13 are 1 chain 1
4a is provided with claw-shaped actuators N4b protruding at predetermined intervals in the driving direction.

Furthermore, tire guide walls 17 are provided at both edges of the inclined surface 12, and the opposing interval gradually narrows toward the tire pull-out direction.
17 is erected, and the outer chain conveyor 1
The tip of 4.14 is inserted under the tire guide wall 17.17.

With such a pull-out device 4, by driving the chain conveyors 13 and 14 in the direction of the arrow X, the spent tires a stored in the hopper 3 are transferred to the attachments of the chain conveyors 13 and 13b
, 14b, and the inclined surface 1 is scraped out in a sparse state.
It is pulled out obliquely upward along line 2.

Then, the used tire a climbs up near both edges of the inclined surface 12.
... are guided by the tire guide wall 17° 17 and moved inward, and finally all the used tires a... are led to the inner chain conveyor 13 and sent to the water removal conveyance device 5 for the next process. Supplied.

In this way, the used tires a... in the hopper 3 are sequentially pulled out of the hopper 3, but in this pull-out device 4, as shown in FIG.
...The used tires a... are piled up randomly on top, and these used tires a... are sequentially moved to the lower end of the slope surface 12 using the component of gravity along the slope surface 12. Since the tires are guided, comparatively small amounts of spent tires a are continuously and smoothly supplied onto the lower end of the inclined surface 1-2.

Therefore, when a large amount of used tires are piled up directly on a surface with a chain conveyor, the weight of the tires presses the bottom used tires strongly against the surface, and the chain conveyor pulls out the tires. This eliminates the inconvenience of having to pull out a large amount of force or having a large number of used tires piled up at the same time, and securely removes only the bottommost used tire a with a small force. It can be withdrawn at any time.

In addition, even in such a case, all the spent tires a piled up in ζL are guided to the lower end of the slope 12 by the rolling action of the free roller row 11, so special equipment and manpower are required. All the spent tires a... in the hopper 3 can be smoothly pulled out without any need.

As shown in FIGS. 4 to 6, the water removal conveyance device 5 has gate-shaped frames 18 erected at predetermined intervals in the tire conveyance direction, and has stop bars 18a of each of these frames 18. A U-shaped swinging arm 19 is suspended, and a tire guide frame 21 is mounted on the top 19a of the swinging arm 19. This tire guide frame 21 is moved by a swinging mechanism (not shown). It is made to swing in the direction of arrow Y.

The tire guide frame 21 is shaped like a gutter with a bottom surface 21a curved downward, and drain holes 21b are bored at required locations on the bottom surface 21a.

With such a water removal conveyance device 5, for example, the amplitude W can be applied to the tire guide frame 21 by operating the swinging mechanism.
When a rocking motion of approximately 300 yen and a vibration frequency of approximately 60 times/min is applied, the used tire a supplied onto one end of the tire guide frame 21 by the pulling device 4 is repeatedly thrown out in the direction of arrow Y. .

As a result, the used tire a is subjected to a severe impact, an uncertain tilt, etc., the water accumulated inside the used tire a is discharged to the outside, and the used tire a is moved to the tire guide frame 21. The tire guide frame 21 is gradually conveyed toward the other end.
From the other end, it is sent to the organizing device 6 for the next process.

In addition, in this water removal conveyance device 5, since the bottom surface 21a of the tire guide frame 21 is curved downward, the used tire a conveyed on the tire guide frame 21 gradually reaches the center of the tire guide frame 21. As a result, the used tires a are lined up in approximately one row.

As shown in FIGS. 7 to 11, the alignment device 6 is comprised of a front-stage device section 22 that is continuous with the water removal conveyance device 5, and a back-stage device section 23 that follows this.

The front-stage device section 22 includes a roller conveyor 24 constituting a tire conveyance path, and a pair of opening/closing plates 2 that are provided in the middle of this roller conveyor 24 and open and close in a double-door style in the downstream direction.
5.25, a tire detector 26.26 provided on the upstream side surface of each of these opening/closing plates 25.25, and the opening/closing plates 25.25.
25 with a predetermined gap between its tips (e.g. soogit)
Hold it in a V-shaped posture so that
A spent tire a that cannot pass through the gap is connected to both opening and closing plates 2.
5. An opening/closing mechanism (
(not shown).

Further, the rear stage device section 23 includes two free roller rows 27, 27 constituting a tire conveyance path, and a chain conveyor 28 provided between these two free roller rows 27, 27. Each roller 27a constituting the roller row 27 is inclined so that its outer end precedes its inner end in the downstream direction.

The chain conveyor 28 has attachments 28b attached to the chain 28a at predetermined intervals for pressing the used tires a, but the attachments 28b are stopped by the quantitative delivery device 7. It is formed into a wedge shape in side view so as not to apply an unreasonable forward force to the used tire a.

In addition, a photoelectric tire detector 29, for example, is provided near the starting end of the rear-stage device section 23, and when a stagnation occurs in the used tires a heading toward the quantitative delivery device 1, the tire detector 29 detects the problem. is detected, and the water removal conveyance device 5 and the drawer device 4 arranged in the previous process are temporarily stopped.

With such an alignment device 6, when a used tire a with an outer diameter of less than 800 nm is sent from the water removal conveyance device 5, the used tire a is first sorted as shown in FIG. The tire is guided by one of the opening/closing plates 25 to the center of the tire conveyance path, and is sent onto the free roller row 27.27 through the gap formed between the opening/closing plates 25.25.

Since each roller 27a constituting this free roller row 27.27 is tilted as described above, the spent tire a is
7 receives a force that converges on the center line of the tire conveyance path, and is finally aligned and supplied to the next quantitative delivery device 7.

Further, when a used tire a having an outer diameter of 80011 or more is sent from the water removal conveyance device 5, the used tire a is first guided by one of the opening/closing plates 25 and placed on the tire conveyance path. The tire detectors 26.26 of both opening/closing plates 25.25 are pressed together as shown in FIG. 9.

Therefore, both opening/closing plates 25.25 open simultaneously, and the free roller row 27.25 opens with the spent tire a aligned.
27, and is directly supplied to the next quantitative delivery device 1.

As shown in FIGS. 12 to 15, the quantitative delivery device 7 includes a pair of opening/closing plates 31 provided at the terminal end of the alignment device 6.
．． 31, a discriminator 32 for discriminating the size of the leading spent tire a whose forward movement is blocked by the opening/closing plate 31.
A control circuit (not shown) that transmits a tire sending signal after a predetermined time corresponding to the determined size of the used tire a, and a control circuit that normally maintains the opening/closing plate 3L31 in a closed state an opening/closing mechanism (not shown) that opens the opening/closing plate 31, 31 when receiving a tire sending signal;
A tire holding mechanism 33 that stops the following used tires a when the opening/closing plate 31.31 is opened to send the leading used tire a forward; and the opening/closing plate 31.31.
The apparatus is equipped with a tire presence/absence detector 34 that confirms the presence of the used tire a sent out from the section and issues a command to the opening/closing mechanism to close the opening/closing plate 31.31.

The discriminator 32 is provided with a first tire detection end 35 for detecting the presence or absence of a tire between the tips of both the opening and closing plates 31.31, and a side surface on the upstream side of each of the opening and closing plates 31. A second tire detection end 36 and a third tire detection end 37 are attached at a predetermined distance from each other, and have the following discrimination function.

That is, a small diameter used tire a. When the opening/closing plate 3L31 comes into contact with the opening/closing plate 3L31, the first and second tire detection ends 35, 36, 36 or the first, second . Third tire detection end 35, 36, 36, 37, 37. is O
Switch to N state and notify that fact.

In addition, when the medium-diameter spent tire a2 comes into contact with the opening/closing plate 31.31, as shown by the broken line in FIG. 13, 1. 1st. The third tire detection end 35, 37, 37 switches to the ON state to notify that fact.

Further, when the large-diameter spent tire a3 comes into contact with the opening/closing plate 3L31, only the first tire detection end 35 switches to the ON state to indicate this, as shown by the two-dot chain line in FIG. Let me know.

On the other hand, the control circuit has a timer corresponding to the sending time of the small diameter used tire a, a timer corresponding to the sending time of the medium diameter used tire a2, and a timer corresponding to the sending time of the large diameter used tire a3. The timer is selectively activated based on the discrimination signal from the discriminator 32.

The delivery time of each of these used tires a1 + a2 y a3 is set in advance so that the amount of delivery of the used tire a per unit time is constant.

In addition, the tire holding mechanism 33 includes a pair of rotating arms 38, 39 arranged at a predetermined interval in the tire conveying direction, and a pair of rotating arms 38, 39, each of which connects the used tire a.
It consists of cylinders 41 and 42 that are pressed against the upper surface, and when it is determined that the leading spent tire a in contact with the opening/closing plate 31, 31 is of large diameter or medium diameter,
As shown in the figure, only the rotation arm 38 on the upstream side operates to hold down the following used tire a, and when it is determined that the leading used tire a that comes into contact with the opening/closing plates 31, 31 has a small diameter. In this case, both pivot arms 38 as shown in FIG.
, 39 work together to hold down the following used tire a.

Further, the tire presence/absence detector 34 is connected to the opening/closing plate 31.31.
A tire detection rod 44 is protruded between two free roller rows 43, 43 provided on the downstream side of the opening/closing plate 3.
This is to confirm the passage of the used tire a sent out from the L31 section.

The tire detection signal from the tire presence/absence detector 34 has the following primary uses in addition to being used as a command signal for closing the opening/closing plate 31, 31 as described above.

That is, when the tire detection signal from the tire presence/absence detector 34 is continuously transmitted for a predetermined period of time or more, the kiln main body 1a of the used tire a is
Since this is evidence that the amount of money being invested is not being made, we are trying to issue a warning to that effect.

Furthermore, if this tire detection signal is not transmitted for a predetermined period of time or more, this is evidence that an abnormality has occurred in any of the quantitative delivery device 7, draining conveyance device 5, or drawing device 4, so an alarm to that effect is issued. I'm trying to make it happen.

However, if such a fixed amount delivery device 7 is used.

The aligned used tires a... are locked and put on standby by a pair of opening/closing plates 31, 31 which are closed in a V-shape in a state that can be opened in the downstream direction in a double-door style. , based on the contact state between the tire detecting ends 36, 36° 37.37 provided intermittently on the tire-related surfaces of both opening/closing plates 31.31 and the waiting leading used tire a. a, and based on this detection result, determine the length of the waiting time so that the average tire supply amount per unit time is approximately constant, and after the waiting time has elapsed, the opening/closing plate 31.31 It is possible to reliably carry out the quantitative delivery process of opening the tire and sending out the leading used tire a.

According to such a fixed amount delivery process, it is possible to achieve the effect of realizing relatively highly accurate fixed amount supply with an extremely simple device.

In other words, originally, in order to keep the average supply amount of used tires constant per unit time, it is necessary to measure the weight of the used tires, but it is necessary to measure the weight of the used tires during transportation. Requires complex equipment.

In contrast, in the present invention, the shape and dimensions of the spent tire a are measured to estimate its approximate weight, and the delivery time is selected based on the results.

Moreover, in measuring its shape and dimensions, a unique method using opening/closing plates 31 and 31 is adopted.

In other words, in this measurement method, when the used tire a is locked by the opening/closing plate 31.31 closed in a V-shape, the opening/closing plate of the used tire a is This was devised by paying attention to the fact that there is a difference in the contact position with respect to the opening/closing plate 31.31, and as mentioned above, in order to keep the used tire a... Multiple tire detection ends 36. 36, 37,
The outer diameter dimension of the used tire a can be detected by the extremely simple means of providing the tire 37.

Therefore, with such a device, an excellent effect can be obtained in that quantitative supply work can be performed with relatively high precision using a very simple device.

The conveying device 8 includes a conveyor 45 that carries the spent tires a on the free roller rows 43, 43 onto the entrance of the kiln main body 1a, and a conveyor 45 that transports the spent tires a discharged at the end of the conveyor 45 into the kiln main body 1a. Inside this duct 46 is a tire detector 47 that detects the passage of the used tire a, and from the time when this tire detector 47 detects the passage of the used tire a, A first tamper 48 that opens after a certain time and a second tamper 49 that opens a predetermined time after the first tamper 48 is closed are sequentially arranged from upstream to downstream.

However, with such a conveyance device, the conveyor 45
When the used tire a is put into the duct 46 by
The used tire a passes over the tire detector 47 and falls onto the first tamper 48.

Thereafter, the first tamper 48 opens downward and the spent tire a falls onto the second tamper 49.

Then, after the first tamper 48 is closed, the second tamper 49 is opened, and the spent tire a on the second tamper 49 is thrown into the kiln main body 1a.

In this case, the inside of the kiln main body 1a is under negative pressure with respect to the atmosphere, but since the two tampers 48 and 49 are alternately opened and closed to charge the spent tires a, the kiln is heated when the tires are charged. There is no inconvenience such as a loss of heat due to cold air being sucked into the main body 1a.

As described in detail above, according to the automatic supply equipment 2 for used tires according to the present invention, as long as the used tires a are put into the hopper 3, the used tires a can be delivered from the hopper 3 as required. The tires are pulled out in portions and sent to the water removal conveyance device 5, and while passing through the water removal conveyance device 5, the water accumulated in the spent tire a is discharged to the outside.

The spent tires a that have passed through the water removal conveyance device 5 are arranged in a single line by an alignment device 6 and are then arranged in a fixed quantity delivery device 7.
and is sequentially and quantitatively delivered from this quantitative delivery device 7.

The spent tires a sent out from the quantitative delivery device 7 are sequentially introduced into the kiln main body 1a via the conveyance device 8.

Therefore, according to the automatic supply method of used tires realized by such automatic supply equipment 2, it is no longer necessary to take out and arrange tires one by one from a random pile, which conventionally had to be done manually. This makes it possible to reliably perform water drainage work or quantitative supply work, which has tended to be uncertain, without requiring any manpower.

Moreover, according to the present invention, the aligned used tires are made to stand by for a required period of time by the pair of opening/closing plates closed in a V-shape as described above, and the sizes of the used tires are checked using the opening/closing plates. Since the waiting time is sequentially determined by the detection, an excellent effect can be obtained in that a fixed amount of used tires can be supplied using an extremely simple device.

The reason why it is possible to supply a fixed quantity of used tires using such a simple opening/closing plate is because the previous process includes the above-mentioned extraction process, water removal conveyance process, and alignment process in sequence. It should also be noted that.

However, it is impossible to automatically supply used tires one by one intermittently unless the piled up used tires are gradually dispersed and pulled out. This is because it is not possible to guarantee a constant supply of used tires, and furthermore, unless they are properly aligned in one line, the size of the used tires cannot be accurately detected using the two opening/closing plates mentioned above.

A waste tire draining and conveying device that is directly used to carry out an automatic method for supplying used tires to a predetermined supply position using methods such as the above. 4 A front-stage device section and a rear-stage device section are arranged in series in the direction of used tire conveyance, and the front-stage device section is provided in the middle of the tire conveyance path and opens and closes in the downstream direction of the tire conveyance path in a double-door manner. A pair of opening/closing plates, a tire detector provided on the upstream side surface of each opening/closing plate, and holding the opening/closing plates in a V-shaped posture so that a gap is formed between the tips thereof;
The apparatus further includes an opening/closing mechanism that simultaneously opens the opening/closing plate when a tire that cannot pass through the gap presses both the tire detectors of the opening/closing plate, and the latter device unit is connected to the tire conveyance path. A used tire comprising two rows of rollers, each of which is tilted so that its outer end precedes its inner end in the tire transport direction. This is a sorting device in which used tires piled up randomly in a hopper or the like are sequentially dispersed by a pull-out device and pulled out in the required amount in one direction, and the pulled-out used tires are swung by a water removal conveyance device. The water accumulated in these used tires is removed by transporting them in a predetermined direction, and then these used tires are arranged in a line by an alignment device, and the aligned used tires are sent downstream through a double door. A pair of opening/closing plates closed in a V-shape in a state that can be opened can be used to lock and standby, and at that time, a plurality of tire detection ends provided on the tire locking surfaces of both opening/closing plates and a standby. The size of the leading used tire is detected based on the contact state with the leading used tire, and based on this detection result, the waiting time is adjusted so that the average tire supply amount per unit time is approximately constant. After the length of the tire is determined, and after the waiting time has elapsed, the opening/closing plate is opened to send out the leading used tire. A device for arranging used tires that is directly used to implement an automatic method for feeding used tires into a feeding position.
