Summary of the Invention

Problems to be Solved by the Invention

[0004] In an electric fusion device, a battery may be used as a power source. In construction using an electric fusion device, for example, joints that require applying a large power of 1 KW or more for about 10 minutes may be constructed a dozen or so times a day. Therefore, the battery used in the electric fusion device is required to have a large capacity. However, in order to keep the weight of the electric fusion device at about 10 Kg and maintain portability, with the current weight energy density of the battery, the capacity of the battery is about 1 KWh. Therefore, even when the battery is fully charged, it can be used for construction only about 5 or 6 times. Therefore, instead of incorporating the battery into the electric fusion device, an easily replaceable battery pack replacement method is adopted.

[0005] Using battery-powered electrofusion equipment in locations where AC power is available is inefficient in terms of battery life. Therefore, AC-powered electrofusion equipment is used in locations where AC power is available. However, if a single construction site has both locations where AC power is available and locations where it is not, it is necessary to either prepare two types of electrofusion equipment—one powered by batteries and one powered by AC—for the construction, or to use only the battery-powered electrofusion equipment while periodically charging the batteries with AC power.

[0006] The present invention has been made in view of the circumstances described above, and aims to provide an electrofusion device that can be powered by batteries in locations where AC power is unavailable, and can be powered by AC power in locations where AC power is available. [Means for solving the problem]

[0007] To solve the aforementioned problems, the present invention proposes the following means. The electrofusion apparatus according to the present invention is an electrofusion apparatus that supplies power to an electrofusion joint and fuses the electrofusion joint with a resin pipe, comprising a case and a power supply unit, wherein the power supply unit is equipped with a battery pack that can be attached to and removed from the case, and the case is capable of receiving an AC adapter connected to an AC power source.

[0008] According to this invention, the power supply unit is equipped with a battery pack that is detachable from the case. The case is also capable of receiving an AC adapter connected to an AC power source. This allows power to be supplied by attaching the battery pack in locations where an AC power source is unavailable. In locations where an AC power source is available, power can be supplied via AC by attaching the AC adapter in the same way as the battery pack. Therefore, a single electrofusion device can be used to freely switch between battery power and AC power, just as easily as changing a battery pack. This allows a single type of electrofusion device to be used at construction sites where AC power is available in some locations and unavailable in others. Consequently, construction efficiency can be improved.

[0009] Furthermore, the system includes a reading means for reading fusion information necessary for the construction of the electrofusion joint, a calculation means for calculating the construction power necessary for the construction of the electrofusion joint from the fusion information read by the reading means, and a determination means for determining whether or not the construction of the electrofusion joint can be started. The battery pack or AC adapter also includes a power supply information notification means for notifying the determination means of the output power of the battery pack or the output power of the AC-DC converter of the AC adapter. The determination means may determine that construction can be started only if the output power exceeds the construction power.

[0010] According to this invention, the determination means determines that construction can only begin if the output power exceeds the construction power. This prevents construction defects that may occur if the electric fusion joint and resin pipe do not melt sufficiently due to insufficient power during construction.

[0011] Furthermore, if the output power falls below the installation power, the system may also be provided with notification means that indicates a request to use a battery pack or AC adapter with a higher output power.

[0012] According to this invention, if the output power falls below the construction power, the device further includes a notification means that prompts the user to use a battery pack or AC adapter with a higher output power. By providing a means to clearly communicate that construction cannot be started in this way, user convenience can be improved.

[0013] Furthermore, the device may be provided with a locking mechanism to control whether the power supply unit can be removed from the case, and the locking mechanism may allow the power supply unit to be removed from the case when the power to the electrofusion device is turned off.

[0014] According to this invention, the locking mechanism allows the power supply unit to be removed from the case when the power to the electrofusion device is turned off. This prevents the power supply unit from being removed while the power is on, which could cause sparks or malfunction of the electrofusion device.

[0015] Furthermore, the locking mechanism may be configured to prevent the power supply unit from being removed from the case unit during the installation of the electrofusion joint.

[0016] During the installation of the electrofusion joint, a high voltage is applied from the power supply unit to the internal circuit of the electrofusion joint. Therefore, if the power supply unit is removed from the case during installation, a large spark may be generated. The locking mechanism prevents the power supply unit from being removed from the case during the installation of the electrofusion joint. This prevents sparks from being generated at the installation site.

[0017] Furthermore, the device may also include a setting unit for changing the settings of the locking means, wherein the setting unit may be able to set a first setting which prevents the power supply unit from being removed from the case unit at all times when the power supply of the electrofusion device is on, and a second setting which prevents the power supply unit from being removed from the case unit only during the installation of the electrofusion joint.

[0018] According to this invention, the setting unit can be configured with a first setting that prevents the power supply unit from being removed from the case unit at all times when the electrofusion device is powered on, and a second setting that prevents the power supply unit from being removed from the case unit only during the installation of the electrofusion joint. This allows the locking mechanism to be appropriately changed according to the conditions of the construction site. Thus, convenience can be improved.

[0019] Furthermore, it further includes a use selection unit for selecting the use of the resin tube, and when the setting of the use selection unit is the first use, the locking means always makes the power supply unit non-removable from the case unit when the power of the electric fusion device is on. When the setting of the use selection unit is other than the first use, the power supply unit may be made non-removable from the case unit only during the installation of the electric fusion joint.

[0020] According to this invention, when the setting of the use selection unit is the first use, the power supply unit is always non-removable from the case unit when the power of the electric fusion device is on. When the setting is other than the first use, the power supply unit is non-removable from the case unit only during the installation of the electric fusion joint. Thereby, in the case of the first use, it is possible to surely prevent the generation of sparks from the electric fusion device, and in the case of other than the first use, it is possible to prevent the failure of the electric fusion device. This configuration exhibits a remarkable effect, for example, when the first use is a gas use, that is, when the resin tube is used for transporting gas.

[0021] In addition, the AC adapter according to the present invention is an AC adapter used in an electric fusion device that supplies power to an electric fusion joint by a battery pack attached to a case unit and fuses the electric fusion joint and a resin tube, and is detachable from the case unit with the battery pack removed.

[0022] According to this invention, it is detachable from the case unit with the battery pack removed. That is, it can be attached to the case unit and used in the same way as the battery pack. Therefore, one electric fusion device can be used by appropriately switching between driving by the battery pack and driving by the AC adapter.

Effects of the Invention

[0023] According to the present invention, it is possible to provide an electric fusion device that can be powered by a battery in a place where an AC power supply cannot be secured, and can be powered by an AC power supply in a place where an AC power supply can be secured.

Brief Description of the Drawings

[0024] [Figure 1] This is an overall view of the electric fusion bonding device according to the present invention. [Figure 2] This is a block diagram of the electric fusion bonding device according to the present invention. [Figure 3] This is a schematic diagram of the AC adapter according to the present invention. [Figure 4] This is a schematic diagram when the AC adapter is used as a charger.

Mode for Carrying Out the Invention

[0025] Hereinafter, referring to the drawings, the electric fusion bonding device 1 according to an embodiment of the present invention will be described. The electric fusion bonding device 1 supplies power to the electric fusion joint 3 and heats the heating wire (heater) provided inside the electric fusion joint 3, thereby fusing the electric fusion joint 3 and the resin tube 4. As shown in FIG. 1, the electric fusion bonding device 1 includes a case portion C, a fusion power supply portion 11, a control portion 12, a control power supply portion 13, a locking means 14, and a power supply portion 2.

[0026] The case portion C houses each component included in the electric fusion bonding device 1. The case portion C particularly houses the power supply portion 2 detachably from the outside and houses the other components inside. Or, the other components are provided facing the outer peripheral surface of the case portion C. Alternatively, they may be housed inside the case portion C when the electric fusion bonding device 1 is stored and taken out from the case portion C for use during work.

[0027] The fusion power supply portion 11 is a part that supplies the power supplied from the power supply portion 2 to the electric fusion joint 3. The fusion power supply portion 11 includes an output cable 111 and an output connector 112. The fusion power supply portion is housed inside the case portion C when the electric fusion bonding device 1 is stored and taken out from the case portion C for use during work. The output cable 111 is a cable that connects the fusion power supply unit 11 and the output connector 112. The output connector 112 is a terminal that connects to the joint terminal 31 provided on the electrofusion joint 3. The joint terminal 31 is the ends of an electric heating element (not shown) provided inside the electrofusion joint 3. In other words, the joint terminal 31 is provided in pairs in the electrofusion joint 3. As shown in Figures 1 and 2, the output cable 111 and the output connector 112 are provided in pairs, similar to the joint terminal 31, and are connected to the joint terminal 31 respectively. This allows power to be supplied from the joint terminal 31 to the electric heating element of the electrofusion joint 3, which is heated and fuses the electrofusion joint 3 with the resin pipe 4.

[0028] The control unit 12 controls the electrofusion operation performed by the electrofusion device 1. Details of each component will be described later. The control power supply unit 13 is the part that supplies power from the power supply unit 2 to the control unit 12. This drives the electrofusion device 1. The locking mechanism 14 controls whether the power supply unit 2 can be removed from the case unit C, as set by the control unit 12. The locking mechanism 14 is provided at the location in the case unit C where the power supply unit 2 is attached. The locking mechanism 14 is, for example, a solenoid that reciprocates a core material. As shown in Figure 2, the locking mechanism 14 prevents the power supply unit 2 from being removed from the case unit C by causing the core material to interfere with the power supply unit 2 attached to the electrofusion device 1. Alternatively, it moves the core material to release the interference with the power supply unit 2, making the power supply unit 2 removable from the case unit C.

[0029] The power supply unit 2 drives the electrofusion device 1. The power supply unit 2 includes a battery pack 2a and may also include an AC adapter 6. Hereinafter, the battery pack 2a and the AC adapter 6 will be referred to as the power supply unit 2 without distinction. The battery pack 2a is detachable from the electrofusion device 1. The battery pack 2a comprises a secondary battery 21, a battery connection terminal 22, a locking mechanism 23, a battery information notification mechanism 24 (power information notification mechanism), and a battery information communication terminal 25.

[0030] The secondary battery 21 is the main component of the battery pack 2a. In this embodiment, the battery pack 2a is a rechargeable battery such as a lithium-ion battery or a nickel-cadmium battery. The secondary battery 21 of the battery pack 2a is charged by the battery charger 5. The battery information notification means 24 notifies the determination means of the control unit 12 of the output power of the secondary battery 21. In this embodiment, output power refers to, for example, the output voltage and maximum output current of the battery pack 2a.

[0031] The battery information communication terminal 25 transmits information regarding the output power notified by the battery information notification means 24 to the power information communication means 126, which will be described later, via the case power information communication terminal 64a provided in the case section C. The battery information communication terminal 25 and the case power information communication terminal 64a are positioned so that they automatically make contact when the battery pack 2a is attached to the case section C.

[0032] The battery connection terminal 22 is the part that contacts the case battery connection terminal 22a provided on the case part C. This allows power to be supplied from the battery pack 2a to the fusion power supply unit 11 and the control power supply unit 13. The battery connection terminal 22 and the case battery connection terminal 22a are positioned in such a way that they automatically come into contact when the battery pack 2a is attached to the case part C. The locking receiver 23 has a shape that corresponds to the core material of the locking mechanism 14. Specifically, it has a receptacle-like shape that receives the core material of the locking mechanism 14. When the core material of the locking mechanism 14 is inserted into the locking receiver 23, it physically interferes with the core material when attempting to remove the battery pack 2a from the case part C. This makes it impossible to remove the power supply unit 2 from the case part C.

[0033] The AC adapter 6 is detachable from the case C from which the battery pack 2a has been removed. In other words, either the battery pack 2a or the AC adapter 6 can be used with the electrofusion splicer 1. The battery pack 2a and the AC adapter 6 are used interchangeably depending on the conditions of the construction site. For example, the battery pack 2a is used in locations where AC power cannot be secured at the construction site. The AC adapter 6 is used in locations where AC power can be secured at the construction site.

[0034] The AC adapter 6 comprises an AC-DC converter 61, a battery connection terminal 22, a locking mechanism 23, a power information notification mechanism 63, a power information communication terminal 64, an AC cable 65, and an AC plug 66. The AC-DC conversion unit 61 is the part that converts the AC current input from the AC power supply into DC current. The battery connection terminal 22 and the locking mechanism 23 have the same configuration as the battery connection terminal 22 and locking mechanism 23 provided on the battery pack 2a.

[0035] The power information notification means 63 notifies the determination means of the control unit 12 of the output power of the AC-DC conversion unit 61. In this embodiment, output power refers to, for example, the output voltage and maximum output current of the AC-DC conversion unit 61. The power information communication terminal 64 transmits information regarding output power notified by the power information notification means 63 to the power information communication means 126, which will be described later, via the case power information communication terminal 64a provided in the case section C. The power information communication terminal 64 and the case power information communication terminal 64a are positioned so that they automatically make contact when the AC adapter 6 is attached to the case section C. The AC cable 65 is a cable that mediates between the AC-DC converter 61 and the AC plug 66. The AC plug 66 is a plug that connects to an AC power source. Both the AC cable 65 and the AC plug 66 have known configurations.

[0036] The AC adapter 6 can be used as a substitute for the battery charger 5 by using the connection adapter 67. The connection adapter 67 has a pair of first connection parts 67a and second connection parts 67b. The first connection part 67a has the same shape as the case power information communication terminal 64a. The power information communication terminal 64 and the battery information communication terminal 25 can be connected to the first connection part 67a. The second connection part 67b has the same shape as the case battery connection terminal 22a. The battery connection terminal 22 can be connected to the second connection part 67b. Using the connection adapter 67 formed in this manner, the battery pack 2a and the AC adapter 6 are directly connected, as shown in Figure 4. This allows the AC adapter 6 to be used as a substitute for the battery charger 5.

[0037] (Configuration of the control unit 12) Figure 2 shows a block diagram of each component housed inside the control unit 12. As shown in Figure 2, the control unit 12 comprises a processing unit 12a, a reading means 121, an operating means 122, a notification means 123, a battery voltage measuring means 124, a storage means 125, a power supply information communication means 126, and a fusion time measuring means 127. These are housed inside the case section C, or provided facing the outer circumferential surface of the case section C. Alternatively, they may be housed inside the case section C when the electrofusion device 1 is stored, and removed from the case section C for use during operation.

[0038] The processing unit 12a processes the information input from each of the configurations described later as appropriate. The processing unit 12a is, for example, a known CPU. The processing unit 12a comprises a calculation means and a determination means. The calculation means calculates the power required for the installation of the electric fusion joint 3 from the fusion information read by the reading means 121. The fusion information includes the voltage and current applied to the electric fusion joint 3 required for installation, the length of time the voltage is applied, and the resistance value of the heater of the electric fusion joint 3. The power required for installation is calculated from the voltage and resistance information.

[0039] The determination means determines whether or not to start the installation of the electrofusion joint 3. The determination means determines that installation can be started only if the output power exceeds the installation power. Specifically, the determination is made by comparing the output power or remaining battery level of the battery pack 2a attached to the case C, or the output power of the AC adapter 6, with the installation power based on the information of the electrofusion joint 3 input from the input means. This prevents installation defects caused by performing installation when the output power of the battery pack 2a or AC adapter 6 is insufficient.

[0040] The reading means 121 reads information relating to the electrofusion joint 3. The reading means 121 is, for example, a known barcode reader. The reading means 121 is housed inside the case part C when the electrofusion device 1 is stored, and is taken out of the case part C and used when in use. Using this, information about the electrofusion joint 3 is read from the joint barcode 32 that is pre-equipped on the electrofusion joint 3 and provided to the processing unit 12a. Using this information, the power load to be applied by the fusion power supply unit 11 is determined, and whether or not the power load can be applied by the battery pack 2a or AC adapter 6 attached to the case part C is determined.

[0041] The operating means 122 is an interface operated by the operator. The operating means is provided facing the outer circumferential surface of the case portion C. The operating means may be, for example, a configuration with multiple push buttons or a configuration using a touch panel. The operating means 122 transmits input from the operator to the processing unit 12a. This allows, for example, input of an instruction to start the fusion of the electrofusion joint 3. In addition, the operating means 122 includes a setting unit and an application selection unit.

[0042] The setting unit changes the setting of the locking means 14. Here, the locking means 14 is a mechanism that controls whether the power supply unit 2 can be removed from the case unit C by setting, as described above. The setting unit can set at least a first setting and a second setting. The first setting is a setting that prevents the power supply unit 2 from being removed from the case unit C at all times when the power supply of the electrofusion device 1 is on. The second setting is a setting that prevents the power supply unit 2 from being removed from the case unit C only during the installation of the electrofusion joint 3.

[0043] The application selection unit selects the application of the resin pipe 4. The application selection unit can set at least a first application and a second application (other than the first application). Here, the first application is, for example, a gas application; that is, when the resin pipe 4 is used for transporting gas. The second application is, for example, a drainage application; that is, when the resin pipe 4 is used for transporting drainage. The locking means 14 is set as follows in accordance with the setting by the application selection unit.

[0044] In other words, if the application selection unit is set to the first application, the power supply unit 2 cannot be removed from the case unit C at all times when the power to the electrofusion splicer 1 is on. If the application selection unit is set to an application other than the first application, the power supply unit 2 cannot be removed from the case unit C only during the installation of the electrofusion joint 3. Thus, the locking mechanism 14 can be automatically configured to match the intended use of the resin pipe 4, in addition to being directly configured by the operator via the setting unit.

[0045] The notification means 123 notifies the user to use a battery pack 2a or AC adapter 6 with higher output power if the output power falls below the construction power required. Specifically, the notification is given when the determination means determines that construction is impossible because the output power of the battery pack 2a or AC adapter 6 falls below the construction power required for the construction of the electrofusion joint 3. The notification is preferably displayed using characters or icons on an LCD screen. Alternatively, it may be given by a buzzer sound or voice. This improves convenience by allowing the worker to easily understand the reason why construction is impossible.

[0046] The battery voltage measuring means 124 measures the voltage of the battery pack 2a attached to the case part C. This allows the remaining battery capacity of the battery pack 2a to be determined. This information is transmitted to the processing unit 12a and used by the determination means to determine whether or not construction is possible. The storage means 125 is a part that stores various information related to the construction of the electrofusion joint 3 by the electrofusion device 1. For example, a known storage device (such as a hard disk) is used for the storage means 125. For example, it stores information about the electrofusion joint 3 that the electrofusion device 1 can handle. This is then compared with the information about the electrofusion joint 3 obtained by the reading means 121 to calculate the construction power required for the construction of the electrofusion joint 3. Alternatively, it stores the number of times construction has been performed since the battery pack 2a was attached to the case part C, and the time the power was used, which is used to calculate the remaining battery level. Alternatively, it stores information about the read joint barcode 32, the applied voltage, current, energizing time, and the success or failure of the fusion, which is used for construction management.

[0047] The power information communication means 126 is used for communication between the battery information notification means 24 provided in the battery pack 2a and the power information notification means 63 provided in the AC adapter 6 and the processing unit 12a. Specifically, it transmits information regarding output power notified by the battery information notification means 24 and the power information notification means 63 to the processing unit 12a, which is then used by the determination means to determine whether or not construction is possible. The fusion time measuring means 127 measures how long power is applied when the electrofusion device 1 fuses the electrofusion joint 3 with the resin pipe 4, and stops applying power when the energizing time read from the joint barcode 32 has elapsed. The above configuration constitutes the electrofusion device 1, which is used for fusing the electrofusion joint 3 with the resin pipe 4.

[0048] As described above, according to the electrofusion splicer 1 of this embodiment, the power supply unit 2 is equipped with a battery pack 2a that can be attached to and removed from the case unit C. The case unit C is also capable of receiving an AC adapter 6 connected to an AC power source. This allows power to be supplied by attaching the battery pack 2a in locations where an AC power source cannot be secured. In locations where an AC power source can be secured, power can be supplied by AC power by attaching the AC adapter 6 in the same way as the battery pack 2a. Therefore, a single electrofusion device 1 can be used to freely switch between battery power and AC power, in the same manner as changing a battery pack 2a. This allows for the use of only one type of electrofusion device 1 in construction sites where AC power is available in some locations and unavailable in others. Thus, construction efficiency can be improved.

[0049] Furthermore, the determination means determines that construction can only begin if the output power exceeds the construction power. This prevents construction defects that may occur if the electric fusion joint 3 and the resin pipe 4 do not melt sufficiently due to insufficient power during construction.

[0050] Furthermore, if the output power falls below the construction power, the system is further equipped with a notification means 123 that displays a message prompting the use of a battery pack 2a or AC adapter 6 with higher output power. By providing a means to clearly communicate that construction cannot be started in this way, user convenience can be improved.

[0051] Furthermore, the locking mechanism 14 allows the power supply unit 2 to be removed from the case unit C when the power to the electrofusion device 1 is turned off. This prevents the power supply unit 2 from being removed while the power is on, which could cause sparks or malfunction of the electrofusion device 1.

[0052] During the installation of the electrofusion joint 3, a high voltage is applied from the power supply unit 2 to the internal circuit of the electrofusion joint 3. Therefore, if the power supply unit 2 is removed from the case unit C during installation, a large spark may be generated. The locking mechanism 14 prevents the power supply unit 2 from being removed from the case unit C during the installation of the electrofusion joint 3. This prevents sparks from being generated at the installation site.

[0053] Furthermore, the setting unit allows for two settings: a first setting that prevents the power supply unit 2 from being removed from the case unit C at all times when the power supply to the electrofusion device 1 is on, and a second setting that prevents the power supply unit 2 from being removed from the case unit C only during the installation of the electrofusion joint 3. This allows the setting of the locking mechanism 14 to be changed as appropriate according to the conditions of the construction site. Thus, convenience can be improved.

[0054] Furthermore, when the application selection unit is set to the first application, the power supply unit 2 is always kept inaccessible from the case unit C when the power to the electrofusion device 1 is on. When the application is not the first application, the power supply unit 2 is kept inaccessible from the case unit C only during the installation of the electrofusion joint 3. This ensures that sparks are not generated from the electrofusion device 1 when the application is the first application, and prevents malfunction of the electrofusion device 1 when the application is not the first application. This configuration is particularly effective, for example, when the first application is for gas, that is, when the resin pipe 4 is used for transporting gas.

[0055] Furthermore, it is detachable from the case part C from which the battery pack 2a has been removed. In other words, it can be attached to the electrofusion device 1 and used in the same way as the battery pack 2a. Therefore, one electrofusion device 1 can be used by switching between being powered by the battery pack 2a and being powered by the AC adapter 6 as appropriate.

[0056] It should be noted that the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, although the battery pack 2a was described as a rechargeable battery, it is not limited to this; a primary battery or a large capacitor could be used instead of the secondary battery 21. Alternatively, instead of reading the information of the electrofusion joint 3 using the reading means 121, the operator may directly input the information of the electrofusion joint 3 using the operating means 122 to provide the processing unit 12a with the necessary information. Furthermore, the settings and operation of the electrofusion device 1 may be performed not by the operating means 122, but by wirelessly connecting other devices (for example, a smartphone or tablet PC).
