IMPROVED CARRIER AND SYSTEM FOR THE MANAGEMENT OF

REPLACEMENT

SECTOR OF THE TECHNIQUE

The following utility model, as the title of the invention states, is an improved roll holder and replacement management system, that is, it refers to an object that meets the dual functionality of serving paper roll holders and at the same time has a system to detect the amount of paper available to be able to manage the need to replace it.

BACKGROUND OF THE INVENTION

Most of the roll holders that can be found in the market today come basically from the technology of the 90s like U9103419. Except for developments or updates in the design, few other advances have existed in this field.

It is true that in recent years, attempts have been made to optimize paper consumption as can be seen in E09290956. The problem with this type of news is that it usually conditions the roll of paper to specific suppliers or there is reluctance to use it due to the doubts of reliability of some devices of this type.

Be it the most classic and extended models or the new models, the main concern of the facilities that use these dispensers is the guarantee that the user has at all times the necessary paper to cover their needs. The exhaustion of the same or the breakdown in the dispenser can cause an unpleasant and embarrassing situation to both the user and the owner of the facilities.

The present invention comes to solve this problem through a system that allows controlling and monitoring the amount of paper present in the different dispensers so that warnings and alerts are generated if necessary. On the other hand, this same control allows to respond to information increasingly required by the environmental systems and certifications implemented in the facilities such as cellulose consumption.

On the other hand, the general design of the roll holder has retained a straight cylinder structure according to the plane of placement of the paper roll. This has been the case to, among other things, avoid using the toilet roll holder as an ashtray and, consequently, encourages smoking in toilets. With the legal changes regarding the restrictions of smoking in confined public spaces, the possibility of generating greater utilities to the holder through its forms opens up without fear of being misled.

In this way, the present invention adds solutions not inherent in its main function. First, it serves as a hanger through a hanger integrated in the structure of the roll holder so that a user can hang any garment (jacket, bag, pullover, bag, ...) for comfort. Secondly, it serves as a support for users' mobiles in a way that avoids any occasional situations such as the fall of pants from the pants to the toilet when doing the operation of sitting on it.

. EXPLANATION OF THE INVENTION

The improved roll holder and replacement management system consists of providing any type of roll holder that can be found in the market with a set of common minimum components. Using a classic roll holder as an example, it consists of a small diameter cylinder where a roll of paper, normally hygienic, can rest through its central pipe. To protect the paper, the cylinder is attached to a chassis to be able to fix the invention to any horizontal surface and, in turn, the chassis is attached to a casing that completely covers except for the bottom. In this lower part there is a rectangular hole through which the paper roll can be pulled for unwinding and use.

According to a first object of protection, the present invention relates to an improved roll holder and replacement management system in a manner characterized by comprising:

- At least one measuring device configured to detect one or more measurement parameters, the weight being preferred.

- A processing unit configured to process the data from the measuring device.

- Communication means configured to transmit said data to an external monitoring unit.

The type of measuring devices will be preferred through a weight sensor. In this way, the amount of paper available in the roll holder can be monitored and the messages can be parameterized and alarmed to detect with sufficient time the need to replace the paper roll. Distance measuring devices may also be valid to detect the level of paper that a roll holder has, although it is interesting as a secondary support device. This is because more paper volume does not necessarily imply more meters of paper since different types of paper can be used (1 or 2 layers, recycled, of greater or lesser density, ...), in addition, the information coming from would be lost of the weight of a paper reel measured in time as it may be, among others:

- Original weight of the paper reel to verify that it meets the specifications of the supplier.

- Average consumption.

- Tips consumption.

- Projection of needs and replacement.

The weight sensor will be located where the roll rests (in a cylinder when unrolled from outside to inside or on a base when unrolled from inside to outside). The distance sensor (backup to the first) will be located in the upper inner part of the chassis focusing on the support. Preferably, a roll opening and closing sensor is located in the chassis.

Optionally, the roll holder contains a noise, temperature and humidity sensor located in the chassis. The purpose of compiling these parameters will depend on the need and ideality of the facilities to measure the quality of their environment. Taking into account that normally, in a public toilet there are multiple toilets with their corresponding toilet roll holders, the existence of these sensors in one of the roll holders would give the approximate parameter for the entire toilet.

The processing unit is responsible for processing the information of the different measuring devices and sensors. This unit has a self-contained battery powered system in such a way that it also feeds the rest of the systems. Through this unit, you configure:

- Identification of the roll holder.

- Tare 0 from which to start measuring to neglect values that may lead to error such as the weight of the central roll of the paper roll.

- Cycle of reading of each sensor of individual form according to requirements. - Encryption of information packets to send.

- Cycle of sending information to monitor it.

- Work mode at all times and battery management (reading mode, standby mode, send mode, low power mode).

With regard to the media, there are different types of communications that can be used to send data such as Bluetooth, Wifi, although a system of LPWAN communications network of the Internet of things is preferably used, such as:

- Sigfox.

- LoRa.

- LTE-M

- Weightless

- Zigbee

The preference for this type of communications is justified by having a long range and low consumption. This allows an improvement in the reading and sending cycles of the sensor readings as well as a significant increase in battery life.

Preferably, the information sent by the media (since it is normal for them to be multiple roll holders) is received wirelessly by a "gateway" or gateway to be transferred to a computer and / or to the "cloud". In this way, you can monitor the status of each roll holder in real time and manage the necessary actions from the facilities themselves or from any external part (even from another city) either from computers and / or from mobile devices such as phones or tablets. In addition, it is configurable to receive messages and alerts even on mobile devices about the need to attend a device. All the information generated is exploitable to generate reports on consumption, peak hours of use of toilets, response time between incidents and paper roll replacement (through the opening and closing sensor), etc.

As with weight measurement systems, ambient noise, temperature and humidity can be optionally monitored.

According to a second object of protection, the present invention relates to an improved roll holder and replacement management system so that it is characterized by comprising:

- A bump on the top of the roll holder, in the far corner as it is left of the toilet.

- Surface to leave mobile.

In addition to the internal technological advance of the roll holder, the external structure also increases the functionality of the roll holder. The protrusion that comes out of the upper part of the roll holder serves as a hanger to be able to hang bags, jackets, cardigans or any other accessory in addition to being able to house a mobile thanks to its convex shape. In this way, extra functionality is added for the convenience of users. This function is especially interesting when, due to the location or use of the toilet, the floors are difficult to keep clean, This allows to avoid leaving different objects on the floor and that these get dirty or wet since in many cases the toilets do not They have hangers anywhere.

On the other hand, the upper part of the roll holder is flat so that it allows to deposit a mobile or a wallet. This form was previously undesirable since it encouraged the use of design as an ashtray. With the ban on smoking in public places, this is already avoided. This functionality is especially interesting since there are few objects that fall into the toilet by accident so that it will now be possible to deposit the objects that we have in our pockets before performing the operation of sitting in the toilet.

PREFERRED EMBODIMENT OF THE INVENTION

As shown in Figures 1, 2, 3 and 4, the improved roll holder and replacement management system consists of providing the roll holders with the ability to transmit information for optimal management of this type in the market. of equipment.

The improved roll holder is formed by a support for the roll (1) that contains a weight sensor. This sensor will preferably be of the Wheatstone bridge type in order to have a measurement with great accuracy. When the sensor is located in the holder, said sensor picks up the amount of paper left in the roll. To detect possible failures in this weight sensor (1), a distance sensor (2) can optionally be incorporated into the roll holder so that the thickness of the roll is detected.

The sensors (1) and (2) are connected to a processing unit (3). This unit is connected to media and a battery-powered autonomous power system. Preferably, the media will be of the LPWAN type, wide area network and low power, so that the autonomy of the roll holder is months or even years. Other forms of communication such as Wifi, Lan or Bluethoot are possible although they may require an external connection, so you would need infrastructure for your installation.

Optionally and to capture more data of interest, you can also have connected temperature, humidity and noise sensors. In case of roll holder with housing, the opening and closing sensor of the roll holder is also incorporated to record of the weight of the roll that is removed and the weight of the roll that is put back.

Figure 1 represents the most common improved toilet roll holder configuration. In this case, the weight sensor is located in the support (1) in the form of a canute centered on the roll holder. The core will preferably be made of steel and will be where the sensor will be fixed although the exterior, which comes in contact with the roll, can be made of aluminum, plastic, steel or any other material that can be easily cleaned. The distance sensor (2) will be located in the upper right inner corner of the roll holder. In the upper right, there is a protuberance that acts as a hanger (4). In the inner hollow of said hanger, the processing unit, communication medium and battery (3) are located. This distribution is valid according to the example in Figure 1 for a roll holder located to the left of a toilet as it is sitting on it. If you want a roll holder to the right of the toilet, the distribution will be in reverse with vertical symmetry, so that the coat rack is further away from the person than the paper. The housing of the roll holder may preferably be made of aluminum or plastic.

Figure 2 depicts the improved toilet roll holder configuration with central extraction. In this case, the weight sensor is located in the support (1) as a base in the holder. The core will preferably be made of steel and will be where the sensor will be fixed while the base that supports the roll and that comes into contact with it can be made of aluminum, plastic, steel or any other easily cleaned material. The distance sensor (2) will be located in the upper right inner corner of the roll holder. In the upper right, there is a protuberance that acts as a hanger (4). In the inner hollow of said hanger, the processing unit, communication medium and battery (3) are located. This distribution is valid according to the example in Figure 1 for a roll holder located to the left of a toilet as it is sitting on it. If you want a roll holder to the right of the toilet, the distribution will be in reverse with vertical symmetry, so that the coat rack is further away from the person than the paper. The housing of the roll holder may preferably be made of aluminum or plastic.

Figure 5 represents the most common improved paper roll holder configuration. In this case, the weight sensor is located in the support (1) as a base in the holder. The core will preferably be made of steel and will be where the sensor will be fixed while the base that supports the roll and that comes into contact with it can be made of aluminum, plastic, steel or any other easily cleaned material. The distance sensor (2) will be located at the top of the roll holder. On the front The processing unit, communication medium and battery (3) are located on the lower right of the roll holder. The housing of the roll holder may preferably be made of aluminum or plastic.

Figure 7 depicts the most common paperless paper roll holder configuration. In this case, the weight sensor is located in the support (1) in the form of a canute centered on the roll holder. The core will preferably be made of steel and will be where the sensor will be fixed, although the exterior, which comes into contact with the roll, will preferably be made of aluminum but may also be made of plastic, steel or any other material that can be easily cleaned. The processing and communication unit (2) will be located within the connection between the roll support and the wall support. Attached to this connecting element and on the opposite side of the roll, there is a protuberance that acts as a hanger, preferably made of steel (4). The battery (3) will be located in the roll holder, which will preferably be made of aluminum (but it can also be made of plastic, steel or any other material for easy cleaning) This distribution is valid according to the example in Figure 7 for a roll holder located to the left of a toilet as it is sitting on it. If you want a roll holder to the right of the toilet, the distribution will be in reverse with vertical symmetry, so that the coat rack is further away from the person than the paper.

As it has been seen in all the examples, and as shown in Figure 8, different sensors (1) (2) are connected to a processing unit that is in turn connected together with media and a system of autonomous battery type power supply (3). Through the media, data from the different sensors is transmitted to a gateway. The preference of the means of communication being LPWAN type is, in addition to its low consumption, that a single gateway can receive data from different distance holders up to kilometers away.

In this way, and as can be seen in Figure 9, an improved roll holder sends data to a gateway. This gateway can be connected directly to a computer to monitor the data or be connected to the Internet so that it can send the information to a computer, to an internet server or, preferably, to the cloud. Through applications, this data can be analyzed to have the roll holders in optimal conditions, being able to send notices of mobile devices of the need to replace a roll of paper, monitor the status of each roll holder, analyze point consumptions, weight of paper consumed in determining times, or any other interesting information for managers and whose data provides the sensors of the roll holder (paper weight, temperature, humidity, etc).
