Description

The present invention relates to an inkjet recording device and an operation method of the inkjet recording device.

For printing, a nozzle that ejects ink supplied under pressure and ejects it as ink particles, a charging electrode that charges the ink particles according to the print content, and a deflection electrode that deflects the ink particles charged by the charging electrode. A well-known inkjet recording apparatus is a "print head" equipped with a gutter for collecting unused ink to record prints on an object to be printed. Such an inkjet recording device is disclosed in detail in, for example, WO2015 / 114814A1 (Patent Document 1).

This type of inkjet recording device is widely used for printing and recording information such as characters and figures on products flowing on a production line. However, the environment in which the inkjet recording device is installed varies, and it is often installed in an environment with a large amount of dust and moisture. Therefore, in a housing called the "main body" of the device, "mechanical devices" that store ink, supply and collect ink, and "electric devices" such as computers and power supplies that drive and control the entire device are stored. There is. Since the power supply that supplies the power required to drive the inkjet recording device is supplied from the outside using a power cord, it is necessary to protect the portion that takes the power into the main body from dust and water.

Regarding such a power cord, an inkjet recording device devised to enhance the waterproof / dustproof performance of the connection portion with the main body is disclosed in Japanese Patent Application Laid-Open No. 2007-223254 (Patent Document 2).

WO2015 / 114814A1 Gazette JP-A-2007-223254A

Patent Document 2 has an inlet connector provided in the opening of the outer wall of the main body, and a power cord fixing portion for fixing the power cord provided around the inlet connector so as to oppose the outer wall of the device. A configuration is disclosed including a base and a cover having a fixing portion for sandwiching the power cord between the base and the power cord fixing portion of the base provided so as to face the base. With this configuration, the waterproof and dustproof performance of the entrance to the main body of the power cord can be ensured, and the work of replacing the power cord can be performed quickly.

However, this Patent Document 2 targets waterproof and dustproof power cords, and does not describe "external devices" such as various sensors and drive devices required for driving an inkjet recording device. Generally, in an inkjet recording device used in a production line, printing is started by detecting the timing at which the product on the conveyor is conveyed to the printing start position. Therefore, a print sensor is installed to detect the print timing. The detection signal of this print sensor is input to an electric device (computer) in the main body, and printing is started by the control of the electric device. Further, since printing needs to be performed according to the transport speed of the product, a speed sensor such as an encoder is installed. The speed detected by the speed sensor is input to an electric device (computer), and the electric device controls to perform a printing operation of the print head according to this speed. Furthermore, a camera is installed on the production line, and the image signal of the camera is input to an electric device (computer) in the main body to monitor whether printing is performed normally. In this way, electrical signals are exchanged (input / output) between an external device (various sensors, etc.) installed outside the main body of the device and an electric device inside the main body. Since the input / output of electrical signals between such external devices and the electrical devices inside the main unit is required to operate normally even in a poor environment, it is necessary to take measures for waterproofing and dustproofing. ..

On the other hand, if any abnormality occurs in the inkjet recording device in use, it is necessary to replace it with a spare inkjet recording device (spare machine) as soon as possible in order to reduce the influence on the production line. Replacing with a spare device requires disconnection of the electrical connection between each external device and the electrical device of the inkjet recording device in use. Further, after this separation, it is necessary to connect an external device and an electric device of a spare machine and to fix a waterproof / dustproof cover (installation work). The work associated with such replacement with a spare machine needs to be performed as quickly as possible in order to shorten the downtime of the production line.

Therefore, an object of the present invention is an operation method of an inkjet recording device and an inkjet recording device that can easily and quickly attach / detach between an external device and an electric device in the main body while ensuring waterproof / dustproof performance. To provide.

Further, in each drawing used for explanation, the same code (number) is used for each common device / device, and each device / device already described may be omitted in the explanation of the later figures. be.

First, the usage state of the inkjet recording apparatus according to the embodiment of the present invention will be described with reference to FIG. As shown in FIG. 1, the inkjet recording apparatus 600 includes a main body 1, a print head 2, a conduit 3, and the like.

Inside the housing of the main body 1, there are devices and equipment such as an ink container for storing ink to be supplied to the print head 2, paths for ink supply and ink recovery, and pumps and solenoid valves provided in the middle of those paths. Is stored. It also houses the machine base for supplying solvent and replenishing ink. Further, the main body 1 stores an electric device (including a computer that executes control of the entire device according to a stored program) for controlling printing in the print head 2 and controlling a pump, a solenoid valve, etc. in the main body. doing. Further, on the front surface of the main body 1, an operation display unit 4 is provided for instructing the electric device regarding the operation of the device, displaying the operating state, and the like. The operation display unit 4 is usually a touch panel type, but the operation display unit 4 is not limited to this. Anything that has an operation function and a display function may be used. The worker operates the operation display unit 4 to give an instruction regarding printing to the electric device (computer). The electric device executes control based on the instruction, and displays necessary contents such as an operating status on the screen of the operation display unit 4.

The print head 2 generates ink particles by receiving ink supplied from an ink container (not shown) in the main body 1 to a predetermined pressure by a supply path, a solenoid valve provided in the middle of the supply path, a pump, or the like. It has a nozzle to make it. Further, the print head 2 is used for a charging electrode that charges the ink particles ejected from the nozzle with a charge corresponding to the printed characters, a deflection electrode that deflects the charged ink particles according to the amount of charge, and printing. It is equipped with gutter to collect the missing ink. The ink particles that have passed through the deflection electrode of the print head 2 fly so as to land on the print target 19A (before printing), and print on the print target. The generation of ink particles, the amount of charge, and the like in the print head 2 are controlled by an electric device (including a computer) in the main body 1. Here, the description of the specific configuration and operation of the print head 2 will be omitted.

The conduit 3 is provided to connect the main body 1 and the print head 2, and passes through a path for supplying and collecting ink, a cable (electric wire) for controlling the print head 2, and the like.

In FIG. 1, the print object 19A conveyed by the conveyor 18 is detected by the print sensor 5. Further, the printed object 19B after printing is imaged by the camera 9. The detection signals and image signals from these sensors and the like are sent to the electrical equipment (not shown in FIG. 1) in the main body 1 via the input / output connection box 12 fixed to the back surface of the main body 1 by a cable. Entered. It also outputs control signals from electrical equipment to external equipment. For example, a control signal is output to the camera 9 to change the area to be imaged, the size of the captured image, and the like. The input / output connection box 12 is used for the electrical connection between such an external device and the electric device. The specific configuration of the input / output connection box 12 will be described later. In this embodiment, a wire harness is used as the cable. That is, the print sensor 5 is connected to the electric device by the wire harness 6, the encoder 7 is connected to the electric device by the wire harness 8, and the camera 9 is connected to the electric device by the wire harness 10. The description of other external devices will be omitted.

In the configuration shown in FIG. 1, the print sensor 5 outputs a detection signal when it detects that the print object 19A conveyed on the conveyor 18 has been conveyed to a predetermined position. This detection signal is input to an electric device (input to a computer via an input / output control unit). As a result, the electric device (computer) can grasp the printing start timing. Further, the transfer speed is detected by the encoder 7 and similarly input to the electric device. Using these detection signals, the electric device outputs a print control signal to the print head 2 in which the ink particle ejection start timing, ejection speed, and the like of the print head 2 are appropriately adjusted. As a result, the print head 2 can generate ink particles at an appropriate speed at an appropriate timing and execute a printing operation on the print target object 19A. The printed object 19B after printing is imaged by the camera 9, and this image signal is transmitted to the electric device. The electric device performs image processing on this image signal and determines whether or not appropriate printing is performed. As a result of the determination, if printing is not performed normally, the operation display unit 4 displays a poor printing state. It is also possible to display a raw image. This allows the operator to know whether normal printing is being performed or not.

Next, according to FIG. 2, the connection between the input / output connection box 12 provided for connecting the external device (print sensor 5, encoder 7, camera 9, etc.) and the electric device in the main body 1 and the wire harness. The structure of the part will be described. FIG. 2 is a perspective view showing the appearance of the back surface of the main body of the inkjet recording device.

In FIG. 2, an input / output connection box 12 is provided on the back surface 26 of the main body 1. The input / output connection box 12 has a role of relaying electrical connection when a wire harness (cable) is used to output drive power or a control signal to an external device or an electric signal from an external device is input. It is a connection box. Although the input / output connection box 12 is installed on the back surface of the main body 1 in this example, it may be installed on the side surface of the main body 1.

The input / output connection box 12 has a base 22 attached to the outer back surface 26 of the main body 1 and a fixed cover 21 attached to the base 22. The fixed cover 21 is attached so as to surround the base 22, has a side surface portion (peripheral cover portion 21C) having a certain width, and can be attached or detached to the central portion thereof. It has an opening with a size. Further, the input / output connection box 12 has a moving cover 23 that is detachably attached to the fixed cover so as to cover the opening of the fixed cover 21. The moving cover 23 has a structure for penetrating a cable (wire harness), and in this example, a cable gland 25 is attached to the penetrating portion. The cable gland provides a more complete seal with the outside. With the moving cover 23 removed from the fixed cover 21, the worker inserts his hand through the opening of the fixed cover 21 and connects the connector to the end of the cable (wire harness in this example) and the connector on the electrical equipment side. It is possible to perform attachment / detachment work with (connection terminal). That is, the reason why the opening is provided in the central portion of the fixed cover 21 is to perform the attachment / detachment work (the work of electrical connection and the work of opening the connection). If the moving cover 23 is attached to the fixed cover 21 after the work, the connection portion between the cable and the electric device (the portion connected by the connector) is cut off from the outside, so that waterproof and dustproof can be realized. Therefore, the moving cover 23 has a size that covers the entire opening provided in the fixed cover 21. A screw 24 is used to attach the fixed cover 21 and the moving cover, and the fixing cover 21 and the moving cover can be easily removed and attached. Reference numeral 21A is a recess (hole) provided in the fixed cover 21. Reference numeral 23A is a convex portion for locking provided at the lower end of the moving cover 23. The convex portion 23A of the moving cover 23 can be inserted into the concave portion 21A of the fixed cover 21. This is used to temporarily lock and hold the moving cover 23 to the fixed cover 21 when the connector is attached / detached (inserted / pulled out of the connector), as will be described later.

Next, a schematic configuration inside the input / output connection box 12 and the main body will be described with reference to FIGS. 3 to 5. FIG. 3 shows a cross-sectional view of the main body 1 and the input / output connection box 12. FIG. 4 is an enlarged view of a portion of the input / output connection box 12 shown in FIG. FIG. 5 is an exploded perspective view showing a component configuration of the input / output connection box. In these figures, the specific connection of each device is omitted except for the connection part between the external device and the electric device.

In FIG. 3, an ink container 31, a flow path board 32, a plurality of pumps 33, and a plurality of solenoid valves 34 are arranged in the lower part of the main body 1. An electric device is arranged in the upper part of the main body 1. That is, in this example, as electrical equipment, power is supplied to the control board 35 having a computer function, the input / output board 37 that controls the input / output between the control board 35 and the external device, and each device, the board, and the like. A power supply 36 is arranged for this purpose. A connector, which is a connection terminal, is provided on the input / output board 37. In this figure, the connection between the control board 35 and the input / output board 37 and the connection for supplying power from the power supply 36 to each device are omitted.

The ink stored in the ink container 31 has an ink supply path, an ink recovery path, and the like configured by the flow path in the flow path board 32 and the pump 33 and the solenoid valve 34 connected in the middle of the flow path. There is. The control board 35 including the computer controls the start / stop of ink supply and ink recovery. That is, the computer function of the control board 35 drives and controls the pump 33 and the solenoid valve 34 to control ink supply and ink recovery. The computer mounted on the control board 35 controls the print head 2 by using an electric signal or an image signal input from an external device via the input / output connection box 12 and the input / output board 37. A first connector (female connector in this embodiment) is provided at the outer end of the input / output board 37. On the other hand, at the end of the wire harness (6,8,10,13,14), a second connector (male type connector in this embodiment) to be connected to the connector is provided.

In FIGS. 3 and 4, the wire harness in the input / output connection box 12 is connected to each external device whose end is not shown. At the other end of the wire harness, a connector 45 for connecting to the connector 44 (connection terminal) of the input / output board 37 is provided. By inserting the connector 45 provided at the other end of the wire harness penetrating the input / output connection box 12 into the connector 44, it is possible to make an electrical connection between the external device and the electric device inside the main body by the connector. can. On the contrary, by pulling out the connector 45 from the connector 44 which is a connection terminal, the electrical connection can be opened (disconnected). Detachment is performed by inserting and removing such a connector. The first connector 44 may be a male connector and the second connector 45 may be a female connector.

As shown in FIG. 4, the base 22 is fixed to the outer back surface 26 of the main body 1 by screws 42. Further, the fixing cover 21 is fixed to the base 22 by screws 41. By this fixing, waterproof and dustproof can be realized. The base 22 is provided with a small hole 22A so that a connector can be inserted. A gasket 53 is used around the hole 22A in order to enhance the waterproof / dustproof function. Further, on the lower side of the base 22, a heat dissipation space 47 separated from the back surface 26 of the main body is formed so that the generated heat can be efficiently dissipated.

In this example, the base 22 and the fixed cover 21 are separated and fixed with screws 41, but the base 22 and the fixed cover 21 may be integrated into an integrated structure. In that case, the fixing work by the screw 41 becomes unnecessary, and the structure becomes simple. However, in this example, once the base and the fixed cover are fixed, it is not necessary to remove them afterwards. Therefore, the base 22 and the fixed cover 21 have a separate structure and are fixed with screws 41.

As shown in FIGS. 4 and 5, the fixed cover 21 has a peripheral cover portion 21C having a constant width at the peripheral portion, and an opening 21B having a size at the central portion where the connector can be attached / detached. Have. Since the moving cover 23 is attached to the fixed cover 21 at the end of the attachment, the size of the opening 21B is smaller than the outer shape of the moving cover 23. The fixed cover 21 is provided with a peripheral cover portion 21C, and when the moving cover 23 is attached to the fixed cover 21, a storage space 43 having a constant volume composed of a base, a fixed cover, and a moving cover is formed. .. A margin portion at the end of the wire harness (cable) can be accommodated in the accommodation space 43. That is, when connecting or opening the cable end to the electric device, a certain length of margin is required at the cable end in order to improve workability. However, at the stage where the moving cover 23 is attached to the fixed cover 21, the problem is how to store the spare portion of the cable provided for improving the workability. Therefore, in this embodiment, the peripheral cover portion 21C having a predetermined width is provided so as to cover the peripheral portion of the fixed cover 21, the accommodating space 43 is formed, and the spare portion of the cable is accommodated in the accommodating space 43. Further, the base 22 and the fixing cover 21 are fixed by screws 41. With such a configuration, waterproofing and dustproofing can be realized by attaching the moving cover to the fixed cover. Further, a gasket 52 is also used between the base 22 and the fixed cover 21 for waterproof / dustproof, whereby the waterproof / dustproof can be further improved.

As shown in FIGS. 4 and 5, since the screw 41 is exposed to the outside of the moving cover 23, it is easy to remove the moving cover 23 from the fixed cover 21 and attach the moving cover 23 to the fixed cover 21. .. That is, when replacing the operating inkjet recording device with an inkjet recording device which is a spare machine, it is not necessary to remove the base 22 and the fixed cover 21 when separating or mounting the external device from the main body, and the screw 24 is used. The moving cover 23 can be attached and detached by attaching and detaching the moving cover 23. That is, in a state where the moving cover 23 is removed from the fixed cover 21, a hand is inserted through the opening 21B of the fixed cover 21 to perform electrical connection and opening (connector attachment / detachment work). In this example, the gasket 51 is also provided between the moving cover 23 and the fixed cover. Further, the moving cover 23 is provided with a cable gland 25 in order to suppress the free movement of the wire harness and facilitate the connector connection. As shown in FIG. 5, the cable gland 25 in this embodiment is composed of a connector main body 25A, a cap 25B, a rubber bushing 25C, and a nut 25D.

Next, the configuration of the moving cover 23 will be described with reference to FIG. 6A and 6B are perspective views showing a specific configuration of the moving cover 23, where FIG. 6A shows the outer surface of the fixed cover 21 and FIG. 6B shows the inner surface of the fixed cover 21.

In FIG. 6, the moving cover 23 is provided with a cable gland 25 for fixing each wire harness penetrating the wire harness so as not to move freely. The moving cover 23 is attached to the fixed cover 21 and fixed using screws 24 so that it can be removed. Note that 25D is an inner nut. Further, 27 is a washer. Further, as is clear from FIG. 6, a convex portion 23A for locking is provided at the lower end portion of the moving cover 23, and engages with the concave portion 21A provided in the fixed cover 21 to attach the moving cover 23 to the fixed cover 21. Allows locking and holding. Such a configuration fulfills the function of sealing dust and moisture, and also works to open the connection between the electric device and the external device of the inkjet recording device in which the external device is in operation, and the work to connect the spare machine and the external device. This has the effect of keeping the moving cover out of the way of work.

Next, the attachment / detachment work between the external device and the electric device by the input / output connection box 12 and the switching operation to the spare machine will be described with reference to FIGS. 7 to 10. FIG. 7 is a perspective view showing the appearance of the main body in a state where the moving cover is removed from the main body and the moving cover is held (temporarily placed). FIG. 8 is a cross-sectional view showing an input / output connection box portion in a state where the moving cover is removed from the main body and held (temporarily placed). FIG. 9 is a perspective view showing the appearance of the main body with the moving cover removed from the main body. FIG. 10 is a cross-sectional view showing an input / output connection box portion in a state where the moving cover is removed from the main body.

First, the procedure for removing the moving cover 23 and opening the electrical connection between the external device and the input / output board 37 will be described with reference to FIGS. 7 and 8. The moving cover 23 can be removed by removing the screw 24 (turning it in the direction opposite to the tightening). A washer 27 is provided so that the screw 24 does not come off from the moving cover 23 when the moving cover 23 is removed from the fixed cover 21. By removing all the fixed screws 24, the moving cover 23 is separated from the main body side and can be moved. Since the moving cover 23 is provided with the cable gland 25, the moving cover 23 is in a state of being supported by the wire harnesses 6, 8, 10, 13, and 14. In this state, the connector is attached and detached. That is, in the example of FIG. 7, the connector 62 connected to the electric wires 6A and 8A at the ends of the wire harnesses 6 and 8 is pulled out, separated from the connector 61 at the end of the input / output board 37, and electrically connected. To open. Similarly, the connector 45 connected to the electric wire 10A at the end of the wire harness 10 is pulled out to be separated from the connector 44 at the end of the input / output board 37. Further, the connector 64 connected to the electric wires 13A and 14A at the ends of the wire harnesses 13 and 14 is pulled out to be separated from the connector 63 at the end of the input / output board 37.

Here, in the attachment / detachment work, if the moving cover 23 is left supported by the flexible wire harness, the work is difficult. Therefore, in this embodiment, the moving cover 23 is fixed by inserting the convex portion 23A having the locking function provided at the lower end portion of the moving cover 23 into the concave portion 21A provided below the fixed cover 21. Can be locked and held. By locking and holding the moving cover 23 to the fixed cover 21, it is possible to prevent unnecessary movement of the moving cover 23 that interferes with the work. That is, it becomes easy to attach / detach the connectors 62, 45, 64 and the corresponding connectors 61, 44, 63. In this way, the connector is attached and detached while the moving cover is held by the fixed cover 21.

In this embodiment, the moving cover is provided with a convex portion and the fixed cover 21 is provided with a concave portion to be fitted with the convex portion to hold the moving cover 23, but the holding structure is not limited to this. For example, if a bag-shaped part having a width slightly larger than the width direction of the lower end of the moving cover 23 is provided at the lower end of the fixed cover 21, the moving cover 23 can be put in the bag-shaped part and held. can. Further, a magnet may be provided on the moving cover 23, and the moving cover 23 may be attracted to and held by the fixed cover 21 or the back surface 26 of the main body by utilizing the attractive force of the magnet.

By separating the connector, the moving cover 23, the wire harness and the connector can be completely separated from the fixed cover 21. That is, as shown in FIGS. 9 and 10, the wire harness and the moving cover portion are completely separated from the main body 1.

Next, a case where the inkjet recording device (first inkjet recording device) that was in operation is replaced with an inkjet recording device (second inkjet recording device) that is a spare machine will be described. First, the moving cover 23 is removed from the first inkjet recording device. Next, pull out all the connect parts on the wire harness side from the connect parts of the electric device in the main body. As a result, the moving cover 23 is separated from the main body side. This state is as shown in FIGS. 9 and 10.

Next, the first inkjet recording device is removed from the production line, and the second inkjet recording device is installed at a predetermined position on the production line (the position where the first inkjet recording device was installed). Subsequently, the convex portion 23A of the moving cover 23 is inserted into the concave portion 21A of the fixed cover 21 of the second inkjet recording device, and the moving cover 23 is held by the fixed cover of the spare machine. After that, the connector provided at the end of the wire harness is inserted (inserted) into the connector (connection terminal) at the end of the electric device of the second inkjet recording device. That is, the connectors 62, 45, 63 provided at the end of the wire harness are inserted into the corresponding connectors 61, 44, 63 on the main body side. As a result, the electrical connection between each wire harness and the input / output board 37 is completed. After that, the moving cover 23 is attached to the fixed cover 21 of the second inkjet recording device by the screw 24. This completes the replacement work with the second inkjet recording device.

As described above, according to the embodiment of the present invention, the waterproof / dustproof performance at the connection portion between the main body and the external device is ensured, and the connection / disconnection between the external device and the electric device in the main body is ensured. The work (detachment work) can be performed easily and quickly.
