Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor material peeling machine for peeling and removing floor materials such as floor tiles from a floor structure.

[0002]

2. Description of the Related Art In current buildings, a floor structure is often used in which a slab formed of reinforced concrete or the like is laid with an underlayer such as mortar, and a tile is adhered to the upper surface of the underlayer.

Further, in stores and offices, it is not uncommon for flooring materials in buildings to be replaced due to reforms in the sales system and office machinery. In such a case, the existing floor material and the adhesive are peeled off from the floor structure and removed, and a new floor material is adhered to the upper surface of the base layer again.

By the way, the work of peeling off the existing flooring material and the adhesive agent for adhering the flooring material to the underlayer has relied on manual work until relatively recently. That is, a large number of workers hold a trowel made of a thin steel plate or the like in their hands and thrust the tip of the trowel between the floor material and the underlying layer to peel off the floor material.

However, such manual work is inefficient, and it is performed in a poor working environment in which dust is scattered along with peeling, and moreover, a work requiring a strong force in a fairly uncomfortable posture. I had to continue for a long time. For this reason, the shortage of manpower in recent years has been spurred, so that the number of workers will not be able to gather even when recruiting at a considerably high wage, or even if the labor is gathered, they will immediately retire.

Therefore, as disclosed in, for example, Japanese Utility Model Laid-Open No. 63-8333, a scraper is oscillatably supported by a manually pushed frame so that the scraper can be oscillated, and a scraper is mounted on the frame by an oscillating device (vibrator). The floor material peeling machine configured to vibrate the floor has come into practical use.

[0007]

This hand-operated floor material peeling machine is capable of peeling a floor material by mechanical force by applying vibration while inserting a scraper blade edge between the floor material and the underlayer. Since it is possible, it seems that the burden on the worker is reduced at first glance.

However, in reality, the scraper needs to overcome the recoil of the floor base to push the frame forward, and the work load is not reduced so much.

Moreover, when one of the wheels provided on both outer sides of the frame rides on the peeled floor material, the tip of the scraper is inclined and floats above the floor surface, so that the floor material cannot be efficiently peeled off.

In order to prevent such a decrease in efficiency, the operator supports the frame so that the wheels are lifted from the floor surface, and while supporting the weight of the floor material peeling machine, overcomes the reaction force of the peeling work. The method of advancing the floor material peeling machine is adopted.

According to this method, in the case of a PVC tile where an expert has a relatively high adhesive force, the adhesive strength is about 5 per hour.
0 m ² about, it is possible to perform the peeling operation of about 70m ² in the case of the adhesive force is weak P tiles relatively adhesives.

[0012] However, this method increases the safety because the work for supporting the weight of the flooring stripping machine is heavy, and the flooring stripping machine may recoil due to the recoil, which may injure the operator. Even above is extremely disadvantageous.

Further, since the conventional floor material peeling machine vibrates the scraper, a very loud impact sound is generated and a considerable noise is radiated to the surroundings. Therefore, in general, the floor material peeling work cannot be performed in the middle of work, and the floor material peeling work is generally performed during holidays, night work, midnight work, etc.

In this way, for the flooring stripping work that is labor-intensive, the working environment is bad (dirty), is dangerous, and the working hours are different from the general working hours, job seekers may have a good working condition. Today, the tendency to choose jobs is extremely high, and it is very difficult to recruit workers even when paying high wages.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a floor material peeling machine in which the burden on the labor of the worker is extremely light and the noise is less likely to occur. It is a thing.

[0016]

In order to achieve the above object, a floor material peeling machine according to the present invention has a traveling device, a traveling drive device for driving the traveling device, and a driving force of the traveling drive device. A trolley having a transmission device for transmitting to the traveling device, and a blade formed on the front portion of the trolley so as to be contactable with the upper surface of the floor base layer and formed to have a width substantially equal to or wider than the width of the traveling device. A blade device is provided, and the present invention will be described in more detail below.

The traveling device used in the present invention is not particularly limited as long as it is generally used as a traveling device, and for example, a crawler type traveling device, a tire type traveling device, or a traveling device combining these is used. can do. Among these, it is recommended to adopt a crawler type traveling device which has a relatively large ground contact area and therefore can withstand a strong traveling force.

Further, when the traveling device is constituted by a tire type traveling device, the constitution is simple and can be implemented at a low cost.

As the traveling drive device used in the present invention, one generally used as a traveling drive device may be used. For example, if it is composed of an engine unit including a fuel tank and an engine, an electric power unit including a storage battery and a motor. Good.

It is preferable to adopt a drive device that does not deteriorate the working environment as much as possible. From this point of view, the electric power unit is most preferable at this point.
However, since the electric power unit is accompanied by various problems such as weak sustainability of the storage battery, low output / weight ratio, and poor efficiency, it is recommended to adopt the engine unit as the traveling drive device.

When an engine unit is adopted as the traveling drive device, the fuel is liquid such as gasoline, kerosene, light oil, methanol, gas such as liquefied petroleum gas, natural gas, hydrogen gas, coal, etc. It may be a hybrid fuel in which a combustible material such as fine powder is mixed with a liquid fuel. Among these fuels, it is recommended to use gasoline which is relatively easy and inexpensive to obtain, and which has a well-developed technique for preventing air pollution due to engine exhaust.

Further, since the traveling drive device is one of the main noise sources, it is preferable to provide a soundproof case for accommodating the traveling drive device in order to enhance the quietness of the work.

The transmission used in the present invention is not particularly limited as long as it is configured to transmit the power of the traveling drive device to the traveling device. For example, a machine having high mechanical efficiency such as a chain transmission mechanism or a gear transmission mechanism. A mechanical transmission mechanism, a hydraulic device, or a composite device of these is used.

Among these various transmission devices, it is recommended to use a hydraulic device which can distribute power easily by piping and which can be connected to a small and powerful output device such as a hydraulic cylinder or hydraulic motor. It

This floor material peeling machine adopts a boarding operation system in which the operator (operator) gets on the floor material peeling machine from the viewpoint of the steering system. It is possible to adopt the walking control method of walking,
In order to reduce the labor of the operator, it is preferable to adopt the boarding operation method.

When the boarding control system is adopted in this way, the trolley is provided with a driver's cab provided with a driver's seat and a control device. In this case, although not particularly limited, in order to reduce the planar projected area of the floor material peeling machine, it is possible to provide a soundproof case for accommodating the traveling drive device in the driver's cab and also use this soundproof case as a driver's seat. The driver's cab may be fixed to the traveling device, but in order to reduce the labor burden on the operator by increasing the degree of freedom of the operator's attitude to monitor the work status of the floor stripping machine. It is preferable that the driver's cab is provided so as to be rotatable with respect to the traveling device, and most preferably, the driver's cab is provided so as to be fully rotatable with respect to the traveling device.

By the way, in the case of adopting the walking control system, a control handle having a control device supported on a carriage is provided.

The blade device used in the present invention has a blade, which is supported on the upper surface of the floor underlayer so as to be groundable, and has a blade formed to have a width substantially equal to or wider than the width of the traveling device, in the front portion of the carriage. However, in order to improve the peeling efficiency of the floor, it is preferable that the width be wider than the width of the traveling device.

The blade device may be fixedly supported on the carriage, but in order to prevent the blade device from coming into contact with the floor and damaging the floor during movement, the blade of the blade device is supported on the carriage so as to be able to move up and down. It is preferable.

When the carriage of the blade device is supported so as to be able to move up and down, the blade device is provided with a blade drive device for driving the blade up and down. This blade drive device may be configured to have its own drive source, but in order to simplify the overall configuration of the floor stripping machine and realize weight reduction, it is driven by a traveling drive device via a transmission device. It is preferable to configure so. For example, when the transmission device is a hydraulic device, it is preferable that the blade drive device be a hydraulic output device such as a hydraulic cylinder or hydraulic motor.

The blade of the blade device is not particularly limited, but the blade can be configured to be swingably supported by the carriage corresponding to the floor surface. In this case, for some reason the running surface of the running device becomes uneven,
When the traveling device gets into the unevenness and the trolley tilts, the blade can be positioned parallel to the floor surface,
As a result, it is possible to prevent the work efficiency from being lowered due to the floating of the blade from the floor.

Further, when the blade is supported by the carriage so as to be swingable corresponding to the floor surface, the blade is supported by the carriage so that the blade device can move up and down, and the blade drive device for driving the blade device up and down. It is preferable to provide a neutral biasing device that biases the blade in a neutral position where the blade is parallel to the running surface. This can prevent the blade lifted from the floor from inadvertently tilting and coming into contact with the floor and damaging the floor.

In the present invention, it is no problem to support the scraper unit including the unit frame, the vibration oscillating device, and the scraper vibratably supported by the unit frame and vibrated by the vibration oscillating device on the carriage. Absent.

In this case, the adhesive stuck to the floor material and the underlayer can be peeled off while applying vibration by the scraper of the scraper unit. In this case, the recoil received by the scraper is eliminated by the frictional force generated by the weight of the floor material peeling machine, and the operator does not need to receive the recoil.

However, since the floor material peeling work using the scraper unit equipped with the vibrating device is apt to generate noise, it is preferable to carry out the work as limited as possible.

When this scraper unit is provided, it can be fixedly supported by the carriage, but in order to prevent the scraper from coming into contact with the floor and damaging the floor during movement, the scraper unit is moved up and down on the carriage. It is preferable to support it as much as possible. Further, in order to prevent the scraper unit from obstructing the field of view required for operating the traveling device and the blade device when the scraper unit is not used, it is preferable to support the scraper unit on the carriage so as to be horizontally swingable.

[0037]

The floor stripping machine of the present invention has the above-mentioned structure, and when the blade is brought into contact with the floor underlayer to run the cart, the blade scratches the adhesive above the floor underlayer and the floor material such as the floor tile. take. The reaction to the scraping is canceled by the traveling force of the traveling device, and the traveling force of the traveling device is absorbed by the ground frictional force of the traveling device generated by the weight of the floor material peeling machine. Therefore, the operator does not have to spend labor other than operating the control device.

Here, the weight of the floor material peeling machine is the sum of the weights of the traveling device, the traveling drive device, the transmission device, the blade device and the like, and in the case of the boarding operation system, the weight of the operator is added to this. And generally 300-500 kg,
Especially, it may be about 350 to 450 kg.

Further, since the blade is moved without vibrating, it is possible to prevent the generation of a hitting sound caused by the blade hitting the underlayer of the floor, the floor material, etc., and it is difficult to generate noise.

and the output of the engine 14 is 3.5 ps / 3000.
rpm, the running speed of the floor material peeling machine is 1.4 km / h, and the ground pressure of the crawler 12 is 0.14 kg / cm ² .

In this floor material peeling machine, the blade cylinder 23 is operated to adjust the lower end edge of the blade 22 to the height of the upper surface of the underlayer of the floor structure, and when the carriage 1 is run, the blade 22 moves to the floor tile. And the adhesive on the back of it, scraping off the floor tile. The reaction to the scraping is canceled by the traveling force of the traveling device, and the traveling force of the traveling device is absorbed by the ground frictional force of the traveling device generated by the weight of the floor material peeling machine.

Therefore, the operator does not have to use the labor other than operating the control device 7, the labor is remarkably reduced as compared with the conventional one, and the floor material peeling machine retreats due to the reaction of the peeling work. There is no danger, the risk of injury due to the retreat of the floor stripping machine is eliminated, and safety is significantly improved.

In particular, in this embodiment, the truck 1 and the cab 3 are
Since the floor material peeling machine can be operated by operating the control device 7 while sitting on the seat 8 provided at the rear of the cab 3, the floor material peeling machine and the wall of the work site can be operated. Since there is almost no danger of being sandwiched between them, the safety is further enhanced.

Further, in this embodiment, in particular, since the driver's cab 3 is provided so as to be fully rotatable with respect to the traveling device 2, the operator can change the direction of the driver's cab 3 to run or peel the flooring peeling machine. This makes it possible to take an optimal posture for monitoring work, improve workability, make mental stress less likely to accumulate, and further reduce labor.

In this floor material peeling machine, the blade 22
Is pushed with the trolley 1 to scrape the floor tile and adhesive,
No noise is generated when the blade 22 hits the floor tile, the adhesive, or the floor underlayer, and noise is less likely to occur. as a result,
It becomes possible to perform peeling work even in the daytime on weekdays when work is generally performed, and it becomes easier to secure human resources.

The noise and vibration to the surroundings are further reduced, and it becomes easier to perform the peeling work even during the daytime on weekdays when work is generally performed, and it becomes easier to secure human resources.

Further, in this floor material peeling machine, the peeled floor tiles, waste materials such as adhesives are removed to the left and right sides of the blade 22, but the blade 22 has a width substantially equal to or wider than that of the traveling device 2. Since the traveling device 2 is formed on the waste material, there is no possibility that the traveling device 2 rides on the waste material, and there is no fear that the blade 22 is lifted up due to the traveling device 2 riding on the waste material, or the workability is deteriorated. Workability can be significantly improved.

Is adapted to the upper surface of the floor underlayer and is prevented from rising from the upper surface of the floor underlayer. As a result, it is possible to prevent the blade 22 from being lifted from the upper surface of the floor base layer and lowering the work efficiency, thereby further improving the workability.

As a result, according to this floor material peeling machine, even for an amateur worker, for example, in the case of a PVC tile having a relatively strong adhesive force, 100 to 120 per hour is obtained.
m ² about, it becomes possible to handle the separating operation of the ^two approximately 200m per hour in the case of a relatively adhesive force is weak P tile adhesive (trade name).

A running force can be obtained, and even when a strong adhesive is used, the floor tile and the adhesive can be reliably separated from the floor base layer.

Further, in this embodiment, since the traveling drive device 4 is composed of the gasoline engine unit, the fuel can be obtained relatively easily and inexpensively, and it is less polluting than the kerosene engine or the light oil engine. Low exhaust gas can be discharged, which is advantageous in preventing deterioration of the indoor working environment.

The pressure oil can be fed from the oil pump 16 by the driving force of No. 4 to drive those hydraulic pressure output devices, and the overall construction of the floor material peeling machine can be simplified.

Further, in this floor material peeling machine, the blade 22
Since the carriage 1 is supported by the carriage 1 so as to be able to move up and down, the blade 22 can be lifted higher from the floor surface during movement, and it is possible to prevent the blade 22 from inadvertently contacting the floor and damaging the floor.

Further, in this floor material peeling machine, the blade 22
Since the neutral urging spring 31 for urging the blade 22 to the neutral position is provided, it is possible to prevent the blade 22 from inadvertently tilting and coming into contact with the floor when the blade 22 is lifted. It is possible to more reliably prevent damage to the blade 22, prevent rattling of the blade 22, and prevent noise due to rattling of the blade 22.

Further, since this floor material peeling machine is equipped with the scraper unit 36, when the adhesive or floor tile that is firmly bonded to the extent that cannot be peeled off by the blade 22 remains locally, this scraper unit 36 By using 36 to push the scraper 42 with the carriage 1 while vibrating the scraper 42, it is possible to reliably peel off the locally remaining adhesive or floor tile.

Moreover, since the scraper unit 36 is supported by the carriage 1 so as to be able to move up and down, the scraper unit 36 can be lifted high from the floor surface during the movement, and the scraper unit 36 carelessly contacts the floor. Can prevent the floor from being damaged.

Further, since the scraper unit 36 is supported on the carriage 1 so as to be horizontally swingable, when not in use, the scraper unit 36 is retracted to a position where it does not hinder the monitoring of the running state and the working state of other work. It is possible,
It is possible to prevent the workability from being reduced due to the scraper unit 36 blocking the field of view, and to improve the workability.
