Description

The present invention relates to a head moving device, and a print-and-cut device and a three-dimensional processing device including the head moving device.

Conventionally, a device having a plurality of heads and performing a predetermined operation on the media or the like by moving the plurality of heads, such as a print-and-cut device for printing on a recording medium and cutting the recording medium, has been known. ing. Patent Document 1 discloses a print-and-cut device including a cutting head and a head feeding device that feeds two heads of a print head. In the head feeding device disclosed in Patent Document 1, only the cutting head (main driving head) is driven by the motor, and the print head (dependent head) is connected to the main driving head and moves. Therefore, a first connecting portion is provided between the main head and the subordinate head, and the main head and the subordinate head are connected or disconnected by the first connecting portion. Further, a second connecting portion for connecting the device main body and the subordinate head is provided, and when the main head and the subordinate head are separated, the device main body and the subordinate head are connected. When the main body of the apparatus and the subordinate head are connected and the main head is moved in a direction away from the subordinate head, the driving force of the main head disengages the connection of the first connecting portion. As a result, only the driving head can be driven independently. Patent Document 1 discloses a head feeding device including a first connecting portion and a second connecting portion that mechanically connect without using a solenoid.

Japanese Unexamined Patent Publication No. 9-66698

By the way, in a head feeding device as disclosed in Patent Document 1, connection and disconnection are performed without grasping what kind of connection state the main head and the dependent head are in. Specifically, the connected state of the main head and the subordinate head means whether or not the main head and the subordinate head are connected, and whether or not the subordinate head and the device main body are connected. In the conventional head feeding device, since there is no means for knowing the connection state of the above two places, the main head and the subordinate head are once connected and the subordinate head and the device are connected before the main head and the subordinate head are made to perform any operation. The first process of connecting with the main body is executed. From that state, the process proceeds to a second process such as separating the main head, disconnecting the connection between the main head and the subordinate head from the main body of the apparatus, or moving the main head to the standby position.

The first process described above is a useless process when the main head and the subordinate head are already connected at the start of the process and the subordinate head and the device main body are connected. In particular, in the head feeding device provided with the second connecting portion of the method disclosed in Patent Document 1, the first process takes time for the following reasons, which is wasteful. The second connecting portion described in Patent Document 1 is configured such that when the dependent head is pushed toward the device main body side, the dependent head and the device main body are connected, and when the dependent head is pushed further from there, the connection is released. That is, the subordinate head is connected to the device main body only at a predetermined lock position, and the connection is released when the subordinate head is pushed in beyond the lock position. Therefore, in connection with the main body of the apparatus, a certain degree of accuracy is required for positioning the dependent head. Therefore, in the first process, the main head that moves the subordinate head returns to, for example, the origin position of the cut, and first confirms its own position. Since such positioning must be performed, in a head feeding device provided with a second connecting portion as shown in Patent Document 1, it takes a particularly long time to execute the first process. Of course, even in the head feeding device provided with the second connecting portion by another method, it takes a considerable amount of time to execute the first process to a greater or lesser extent. Such waste is caused by the fact that the conventional head feeding device does not have a means for knowing the connected state of the main head and the dependent head and the connected state of the dependent head and the device main body.

The present invention has been made in view of this point, and an object of the present invention is to provide a head moving device in which a plurality of heads are connected and which can know the connected state of the head moving devices. .. Another object of the present invention is to provide a print-and-cut device and a three-dimensional processing device provided with such a head moving device.

The head moving device according to the present invention slidably engages the guide rail extending in the main scanning direction with the guide rail, and the first carriage on which the first head is mounted and the main carriage rather than the first carriage. The guide rail is slidably engaged with the guide rail on the side of the first main scanning direction, which is one of the scanning directions, and the second carriage on which the second head is mounted and the first carriage are moved along the guide rail. A connecting mechanism that connects the main scanning direction moving device, the measuring device that measures the distance that the main scanning direction moving device has moved the first carriage, and the first carriage and the second carriage with a first connecting force. The second carriage is provided with a lock mechanism for fixing the second carriage so as not to be slidable, and a control device. The control device has a connection control unit that brings the first carriage and the second carriage into the first state. The first state is a state in which the first carriage and the second carriage are connected by the connecting mechanism, and the second carriage is fixed by the locking mechanism. The connection control unit includes a connection determination unit. The connection determination unit moves the first carriage in the main scanning direction so as to move the first carriage in the second main scanning direction, which is the opposite direction of the first main scanning direction, with a first driving force weaker than the first connecting force. While driving the device, the moving distance of the first carriage measured by the measuring device is taken in. Then, when the moving distance is less than the predetermined distance, it is determined that the first carriage and the second carriage are in the first state, and when the moving distance is equal to or more than the predetermined distance, the first carriage is determined to be in the first state. It is determined that the 1 carriage and the 2nd carriage are in a state other than the 1st state.

According to the head moving device, the connected state of the first carriage and the second carriage can be confirmed by driving the first carriage with a weak driving force that does not disconnect the connection between the first carriage and the second carriage. .. That is, in the first state in which the first carriage and the second carriage are connected and the second carriage is fixed by the locking mechanism, the first carriage can move at most by the play of the locking mechanism and the connecting mechanism. However, the travel distance is less than a predetermined distance. On the contrary, in the state where one or both of the first carriage and the second carriage are connected and the second carriage is not fixed by the locking mechanism, the first carriage can move along the guide rail, and the movement thereof. The distance is greater than or equal to the predetermined distance. Therefore, by measuring the moving distance of the first carriage, it is possible to determine whether or not the first carriage and the second carriage are in the first state. As a result, for example, if the first carriage and the second carriage are already in the first state, the transition work to the first state is omitted, and if it is not the first state, the transition work to the first state is performed. It is also possible to make the carriage.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a print-and-cut device according to an embodiment. As shown in FIG. 1, the print-and-cut device 1 according to the present embodiment is a device capable of printing and cutting on the medium 200. Although not shown, the medium 200 is, for example, a sealing material composed of a mount and a release paper laminated on the mount and coated with an adhesive. However, the medium 200 is not particularly limited as long as it is a medium capable of printing and cutting. The medium 200 may be a recording paper, a resin sheet, or the like. In the present specification, "cutting" and "cutting" refer to the case of cutting the entire medium 200 in the thickness direction (for example, the case of cutting both the backing paper and the release paper of the sealing material) and the case of cutting the medium 200 in the thickness direction. This includes the case of cutting a part (for example, the case of cutting only the release paper without cutting the backing paper of the sealing material).

The print-and-cut device 1 includes a platen 2 that supports the medium 200, a cutting head 31 that cuts the medium 200 supported by the platen 2, and a print head 41 that prints on the medium 200 supported by the platen 2. I have. The cutting head 31 is mounted on the first carriage 30. The print head 41 is mounted on the second carriage 40. The cutting head 31 is an example of a “first head”. The print head 41 is an example of a “second head”. Although the details will be described later, the first carriage 30 and the second carriage 40 are configured to be movable in the Y direction shown in the drawing. Hereinafter, the Y direction is referred to as a main scanning direction or a left-right direction, and the X direction, which is a direction perpendicular to the Y direction, is referred to as a sub-scanning direction or a front-back direction. Further, among the main scanning directions Y, the direction corresponding to the right side is also referred to as the first main scanning direction Y1, and the direction corresponding to the left side is also referred to as the second main scanning direction Y2. The main scanning direction corresponds to the width direction of the medium 200, and the sub-scanning direction corresponds to the longitudinal direction of the medium 200. The symbols U, D, F, Rr, L, and R in FIG. 1 represent up, down, front, back, left, and right, respectively.

The platen 2 is provided with a grit roller 11. The grit roller 11 rotates by being driven by a feed motor 13 (not shown in FIG. 1, see FIG. 5). A guide rail 21 is provided above the platen 2. The guide rail 21 extends in the left-right direction. A pinch roller 12 is provided below the guide rail 21. The pinch roller 12 is arranged above the grit roller 11. The pinch roller 12 is configured to swing up and down so that it can approach and separate from the grit roller 11. When the grit roller 11 rotates with the medium 200 sandwiched between the pinch roller 12 and the grit roller 11, the medium 200 is conveyed forward or backward. Although only three grit rollers 11 and two pinch rollers 12 are shown in FIG. 1, more grit rollers 11 and pinch rollers 12 are actually arranged in the main scanning direction, respectively. The grit roller 11, the pinch roller 12, and the feed motor 13 constitute a sub-scanning direction moving mechanism 10 that moves the medium 200 relative to the cutting head 31 and the print head 41 in the sub-scanning direction X.

FIG. 2 is a front view of the first carriage 30 and the second carriage 40. As shown in FIG. 2, the cutting head 31 is supported by the guide rail 21 via the first carriage 30. The print head 41 is supported by the guide rail 21 via the second carriage 40. The first carriage 30 and the second carriage 40 are movably engaged with the guide rail 21 in the left-right direction.

As shown in FIG. 2, a cutter 33 is attached to the cutting head 31 via a solenoid 32. The solenoid 32 is controlled by the control device 100 (see FIG. 1). When the solenoid 32 is turned ON / OFF, the cutter 33 moves in the vertical direction and comes into contact with the medium 200 or separates from the medium 200. A first connecting member 51 made of a permanent magnet is fixed to the right side surface of the first carriage 30. Further, a flat plate-shaped light-shielding plate 73 is fixed to the first carriage 30.

A belt 22 extending in the left-right direction is fixed to the upper part of the back surface of the first carriage 30. The belt 22 is connected to the scan motor 23 (see FIG. 5). When the scan motor 23 rotates, the belt 22 travels in the left-right direction. As a result, the first carriage 30 moves in the left-right direction. The scan motor 23 is controlled by the control device 100. The guide rail 21, the belt 22, and the scan motor 23 constitute a main scanning direction moving mechanism 20 that moves the first carriage 30 in the main scanning direction Y.

The print head 41 of the second carriage 40 includes a recording head 42 having a plurality of nozzles (not shown) for ejecting ink. Here, the print head 41 includes five recording heads 42. The five recording heads 42 eject five different colors, for example, yellow ink, magenta ink, cyan ink, black ink, and white ink. However, the number of recording heads 42 is not limited to five. Further, the color of the ink ejected by the recording head 42 is not limited at all.

In the present embodiment, the print head 41 is composed of an inkjet head that ejects ink, but the printing method of the print head 41 is not limited to the inkjet method, and the print head 41 is not limited to the inkjet head. The print head 41 may be, for example, a print head that performs dot impact printing.

A second connecting member 52 made of, for example, an iron flat plate is provided on the left side portion of the second carriage 40. The second connecting member 52 is detachably connected to the first connecting member 51 of the first carriage 30. The first connecting member 51 and the second connecting member 52 form a connecting mechanism 50 that detachably connects the first carriage 30 and the second carriage 40. In the present embodiment, the connecting mechanism 50 utilizes a magnetic force. However, the connecting mechanism 50 is not limited to one that utilizes magnetic force, and may have other configurations such as an engaging member. On the right side portion of the second carriage 40, a first lock member 60L of the lock mechanism 60 for fixing the second carriage 40 so as not to be slidable is provided.

Side frames 3L and 3R are arranged on the left and right ends of the platen 2. The guide rail 21 is supported by both side frames 3L and 3R. The side frame 3R on the right side is provided with a second lock member 60R of the lock mechanism 60. By connecting the second lock member 60R and the first lock member 60L of the second carriage 40, the lock mechanism 60 fixes the second carriage 40 to the right side frame 3R.

FIG. 3 is a sectional view taken along line III-III of FIG. 2, which is a schematic view showing the internal structure of the first lock member 60L. In FIG. 3, only the first lock member 60L is shown, and the other members are not shown. As shown in FIG. 3, the first lock member 60L includes a cover 61 and a slide member 62. The cover 61 is fixed to the right side surface of the second carriage 40. The slide member 62 is housed inside the cover 61. The width of the cover 61 in the front-rear direction is larger than the width of the slide member 62 in the front-rear direction, and the slide member 62 can move in the front-rear direction inside the cover 61. A groove 61A and a groove 61B extending in the left-right direction are formed on the top surface inside the cover 61. A ball 62A that is urged upward by a spring and can move in the vertical direction is attached to the top surface of the slide member 62. Further, the pin 63 protrudes from the bottom surface of the slide member 62. The pin 63 is urged downward by a spring and is configured to be movable in the vertical direction. A hole 61C is provided on the bottom surface of the cover 61. The pin 63 protrudes from the hole 61C to the outside. Therefore, when a backward force is applied to the pin 63, the slide member 62 takes a position on the rear side in the cover 61, and the ball 62A engages with the groove 61A on the rear side. Further, when a forward force is applied to the pin 63, the slide member 62 takes a position on the front side in the cover 61, and the ball 62A engages with the groove 61B on the front side.

FIG. 4 is a perspective view of the second lock member 60R. The second lock member 60R is a flat plate-shaped member on which a slope, a step, or the like is formed. When the second carriage 40 moves to the right and the first lock member 60L and the second lock member 60R come into contact with each other, the pin 63 of the first lock member 60L first rides on the inclined surface 64 of the second lock member 60R. .. At this time, the slide member 62 is positioned on the front side in the cover 61. Since the pin 63 expands and contracts in the vertical direction, it gets over the inclined surface 64 and reaches the corner 65A of the step portion 65. The step portion 65 is lower than the uppermost portion of the inclined surface 64. Therefore, when the pin 63 reaches the corner 65A, even if the scan motor 23 is driven so as to move the second carriage 40 to the left, the pin 63 hits the step and the second carriage 40 does not move. This is the locked state in which the locking mechanism 60 fixes the second carriage 40.

When the second carriage 40 is moved to the right from the locked state, the pin 63 comes into contact with the first guide surface 66. The first guide surface 66 is a vertical plane extending from the front left to the rear right. Upon contact with the first guide surface 66, a backward force is applied to the pin 63. Therefore, the slide member 62 moves to a position on the rear side inside the cover 61. This state is an unlocked state in which the fixing is released by further pushing the second carriage 40 to the right from the locked state. When the scan motor 23 is driven so as to move the second carriage 40 to the left from the unlocked state, the first lock member 60L is released from the second lock member 60R as the second carriage 40 moves. At that time, the pin 63 comes into contact with the second guide surface 67 and receives a forward force. The slide member 62 returns to the front position inside the cover 61 by its forward force.

In this way, when the second carriage 40 is moved to a predetermined lock position, the lock mechanism 60 is in a locked state and fixes the second carriage 40. At this lock position, there is a "play" that roughly corresponds to the difference between the length of the pin 63 in the left-right direction and the length L1 of FIG. 4, and within this range, the second carriage 40 can be moved in the locked state. can. That is, in terms of the positioning accuracy of the second carriage 40, the locked state can be achieved by positioning the second carriage 40 with an accuracy that allows the pin 63 to be inserted between the lengths L1. The width of this lock position is, for example, about 2 mm.

Further, when the second carriage 40 is further moved to the right from the locked position, the lock mechanism 60 is unlocked and the second carriage 40 is released from being fixed. There is also "play" in this unlocked position, and the second carriage 40 can move in the unlocked state until the pin 63 hits the vertical plane 68 in FIG. That is, the distance that the second carriage 40 can move from the time the lock mechanism 60 is unlocked until the pin 63 hits the vertical surface 68 is the width of the unlock position, which is also, for example, about 2 mm.

As shown in FIG. 2, a cap 81 is provided below the second carriage 40. The cap 81 is a member that prevents the ink in the nozzle of the recording head 42 from drying and sticking. The cap 81 is made of rubber or the like. The cap 81 is supported by the cap moving mechanism 82. The cap 81 is attached to or separated from the nozzle surface of the recording head 42 from below by driving the cap moving mechanism 82. The configuration of the cap moving mechanism 82 is not limited, but includes, for example, a motor. The position where the cap 81 can be mounted on the nozzle surface of the recording head 42, that is, the position directly above the cap 81 is the standby position of the second carriage 40. In principle, the second carriage 40 stands by at this standby position except when printing is executed. In the standby position, the second carriage 40 is fixed by the lock mechanism 60. The standby position is one of the lock positions of the lock mechanism 60. The standby position of the first carriage 30 is a position when the first carriage 30 is connected to the second carriage 40 in the standby position, and the first carriage 30 also waits in this standby position in principle except when printing is executed. There is.

A suction pump 83 is connected to the cap 81 via a tube or the like. The suction pump 83 sucks the ink in the nozzle of the recording head 42 with the cap 81 attached to the recording head 42. The cap 81, the cap moving mechanism 82, and the suction pump 83 constitute the capping device 80. The cap moving mechanism 82 and the suction pump 83 of the capping device 80 are communicably connected to the control device 100 and controlled by the control device 100.

An origin sensor 70 is provided at a position between the first carriage 30 and the second carriage 40 in the standby position. The origin sensor 70 is a photoelectric sensor in this embodiment. However, the type of the origin sensor 70 and the like are not limited. The origin sensor 70 includes a floodlight 71 that irradiates detection light for object detection, a receiver 72 that receives detection light from the floodlight 71, and a main body (not shown). The floodlight 71 is installed with the light projecting surface that emits the detection light facing upward, and irradiates the detection light upward. The light receiving device 72 is installed so that the light receiving surface that receives the detected light faces the light projecting surface of the floodlight 71. When there is no shield between the floodlight 71 and the receiver 72, the receiver 72 receives the detection light emitted by the floodlight 71. When a shield exists between the floodlight 71 and the receiver 72, the detection light emitted by the floodlight 71 is blocked by the shield, and the receiver 72 does not receive the detection light. The main body of the origin sensor 70 is set to transmit (ON) a signal when the light receiver 72 does not receive the detection light. When the light receiver 72 receives the detection light, the output of the origin sensor 70 is OFF. The origin sensor 70 is electrically connected to the control device 100 and transmits a signal to the control device 100.

As shown in FIG. 2, the shading plate 73 is installed at a height between the light emitting surface of the floodlight 71 and the light receiving surface of the light receiving device 72. Although not shown, the light-shielding plate 73 is installed at the same front-rear position as the floodlight 71 and the receiver 72. The origin sensor 70 detects the position of the first carriage 30 depending on whether or not the light shielding plate 73 shields the detection light. When the detection light is shielded by the origin sensor 70, the first carriage 30 is located in the vicinity of the origin sensor 70. When the detection light is received, the first carriage 30 is located at a position other than the vicinity of the origin sensor 70. In other words, when the first carriage 30 is located near the origin sensor 70, the control device 100 receives the signal from the origin sensor 70, and when the first carriage 30 is located near the origin sensor 70, The control device 100 does not receive the signal from the origin sensor 70. As will be described in detail later, the leftmost position in the range in which the origin sensor 70 detects the presence of the first carriage 30 is the origin position of the first carriage 30.

As shown in FIG. 2, when the first carriage 30 is in the standby position, the light-shielding plate 73 blocks the detection light from the floodlight 71. Therefore, when the first carriage 30 is in the standby position, the origin sensor 70 is ON. Further, the origin sensor 70 is ON when at least the first carriage 30 and the second carriage 40 are connected and the second carriage 40 is in the locked position or the unlocked position, even if the position is not exactly in the standby position. However, from the situation where the origin sensor 70 is ON, the positions and the connected states of the first carriage 30 and the second carriage 40 cannot be determined, and there may be various cases. Further, when the origin sensor is OFF, the first carriage 30 is separated from the origin sensor 70 to the left, and is not in a state of being fixed to the right side frame 3R via at least the second carriage 40. However, other states are unknown from the signal of the origin sensor 70, and there may be various cases.

As shown in FIG. 1, the print-and-cut device 1 includes an upper cover 4 that constitutes an upper housing. Side covers 5L and 5R are provided on the left side of the side frame 3L and on the right side of the side frame 3R, respectively. An operation panel 110 having a button and a display is arranged on the front surface of the right side cover 5R. A stand 6 with casters is provided below the platen 2.

Although not shown, the print-and-cut device 1 includes a supply roller around which the medium 200 before printing is wound. The supply roller is arranged diagonally downward after the platen 2. At the time of printing, the medium 200 wound around the supply roller is conveyed forward via the platen 2.

As shown in FIG. 1, a control device 100 that controls various operations of the print-and-cut device 1 is housed in the vicinity of the right end of the print-and-cut device 1. FIG. 5 is a block diagram of the print and cut device 1 according to the present embodiment. As shown in FIG. 5, the control device 100 is communicably connected to the feed motor 13, the scan motor 23, the recording head 42, the solenoid 32, the cap moving mechanism 82, and the suction pump 83, and can control them. It is configured in. Further, the control device 100 is electrically connected to the origin sensor 70 and receives a signal from the origin sensor 70. The control device 100 includes a print control unit 101, a cutting control unit 102, a connection control unit 103, and a capping control unit 107.

The configuration of the control device 100 is not particularly limited. The control device 100 is, for example, a microcomputer. The hardware configuration of the microcomputer is not particularly limited, but for example, an interface (I / F) for receiving print data or the like from an external device such as a host computer, and a central processing unit (CPU: central) for executing control program instructions. Processing unit), ROM (read only memory) that stores programs executed by the CPU, RAM (random access memory) that is used as a working area for deploying programs, memory that stores the above programs and various data, etc. It is equipped with a storage device. The control device 100 does not necessarily have to be provided inside the print-and-cut device 1. For example, the control device 100 is installed outside the print-and-cut device 1 and can communicate with the print-and-cut device 1 via wire or wirelessly. It may be a computer or the like connected to.

The print control unit 101 executes printing. The print control unit 101 ejects ink from each recording head 42 of the print head 41 while moving the first carriage 30 in the main scanning direction Y by driving the scan motor 23. At this time, the second carriage 40 on which the print head 41 is mounted is connected to the first carriage 30. Therefore, the print head 41 is moved in the main scanning direction Y by driving the scan motor 23. As a result, one scanning line is printed. After the print head 41 has been moved in the main scanning direction Y, the feed motor 13 is driven to convey the medium 200 to the position of the next scanning line in the sub-scanning direction X. When the sub-scanning direction X of the medium 200 is conveyed, the scan motor 23 is driven again and the recording head 42 is driven to print the next scanning line. Hereinafter, the same operation is repeated until the end of printing.

The cutting control unit 102 executes cutting. The cutting control unit 102 drives the scan motor 23 and the feed motor 13 to move the first carriage 30 two-dimensionally relative to the medium 200. At this time, the first carriage 30 is separated from the second carriage 40 and moves independently. When the solenoid 32 is turned on, the cutter 33 can be pressed against the medium 200. By moving the cutting head 31 relative to the medium 200 while pressing the cutter 33 against the medium 200, the medium 200 can be cut along an arbitrary cut line.

In this way, during printing and cutting, the position of the first carriage 30 in the main scanning direction Y and the position of the medium 200 in the sub-scanning direction X are grasped and controlled. The scan motor 23 and the feed motor 13 are, for example, servomotors, and as shown in FIG. 5, the scan motor 23 and the feed motor 13 are internally provided with encoders 23A and 13A for measuring the rotation angle of the motors, respectively. The encoders 23A and 13A each transmit a pulse signal, for example, for each rotation of the motor. The encoders 23A and 13A are connected to the control device 100, and the control device 100 receives the pulse signals from the encoders 23A and 13A. Since the moving distance related to one rotation of the motor is determined by the scan motor 23 and the feed motor 13, the control device 100 can recognize the moving distances of the first carriage 30 and the medium 200. Thereby, the control device 100 can grasp the positions of the first carriage 30 and the medium 200, and can control the positions.

The connection control unit 103 controls the connection operation between the first carriage 30 and the second carriage 40 and the fixing operation of the second carriage to the right side frame 3R. The connection control unit 103 includes a first connection control unit 104, a second connection control unit 105, and a third connection control unit 106. The first connection control unit 104 controls the scan motor 23 to put the first carriage 30 and the second carriage 40 into a standby state, which will be described later. In the standby state, the first carriage 30 and the second carriage 40 are connected, and the second carriage 40 is fixed to the right side frame 3R by the lock mechanism 60. The second connection control unit 105 releases the lock mechanism 60 from the standby state and shifts the first carriage 30 and the second carriage 40 to a print-executable state. The third connection control unit 106 releases the connection by the connection mechanism 50 from the standby state, separates the first carriage 30 from the second carriage 40, and shifts the first carriage 30 to a state in which cutting can be performed.

The capping control unit 107 caps the print head 41 mounted on the second carriage 40 in the standby state. The capping control unit 107 drives the cap moving mechanism 82 to attach the cap 81 to the recording head 42. Further, the capping control unit 107 drives the suction pump 83 to suck the ink in the nozzle periodically or appropriately.

As can be seen from the above, the "printable state" related to the control of the second connection control unit 105 and the "cuttable state" related to the control of the third connection control unit 106 are both controlled by the first connection control unit 104. Depart from the "standby state" related to. Further, the attachment of the cap 81 to the recording head 42 related to the control of the capping device 80 is also executed in the “standby state”. That is, in any of the above cases, it is necessary to first establish a "standby state". This is because there is no means for measuring the position of the second carriage 40 and a means for moving the second carriage 40 independently. Further, the means for separating the first carriage 30 from the second carriage 40 is the lock mechanism 60.

Further, regardless of whether the state is shifted to the "printable state" or the "cuttable state", the certainty of the operation cannot be guaranteed unless the "standby state" is configured once. For example, when the power is turned off and the first carriage 30 and the second carriage 40 are manually moved, there is no means for grasping the current situation, so it is necessary to temporarily create a "standby state" for the next operation. be. However, providing a means for moving the second carriage 40 independently and measuring its position causes an increase in cost.

In view of the above circumstances, the print-and-cut device 1 according to the present embodiment is configured to save the time required in the process of shifting the first carriage 30 and the second carriage 40 to the standby state. It is an and cut device. Therefore, for comparison, the process of shifting to the standby state by the conventional print-and-cut device will be described first. The conventional print-and-cut device according to the following description is the same as the print-and-cut device 1 according to the present embodiment except for the operation of shifting to the standby state, and has the same configuration. Therefore, in the description of the process of shifting to the standby state by the conventional print-and-cut device, the same reference numerals as those of the print-and-cut device 1 according to the present embodiment are used.

FIG. 6 is a flowchart showing a process of shifting to the standby state by the conventional print and cut device 1. As shown in FIG. 6, the first step of the process of shifting to the standby state by the conventional print-and-cut device 1 is step S10 for moving the first carriage 30 to the temporary origin position. Step S10 includes four steps, steps S11, S11A, S12, and S13. In step S11, the ON / OFF state of the origin sensor 70 is confirmed. When the origin sensor 70 is ON in step S11 (when step S11 is “YES”), the step proceeds to step S12. When the origin sensor 70 is OFF in step S11 (when step S11 is “NO”), the step proceeds to step S11A and then to step S12. Step S11A is a step of turning on the origin sensor 70 once in order to create the same situation as in the case where step S11 is “YES”.

In step S11A, the first carriage 30 travels in the first main scanning direction Y1 (rightward), is decelerated and stopped at the timing when the origin sensor 70 is turned from OFF to ON.

In step S12, the first carriage 30 travels in the second main scanning direction Y2 (leftward), is decelerated and stopped at the timing when the origin sensor 70 is turned from ON to OFF. 7A to 10B are front views showing the positions of the first carriage 30 and the second carriage 40 in step S12. Although details will be described later, FIGS. 7A to 10B show four connected states that the first carriage 30 and the second carriage 40 can take at the start of step S12, respectively. Further, FIGS. 7B, 8B, 9B, and 10B show the states after the end of step S12 when the step S12 is started from the states of FIGS. 7A, 8A, 9A, and 10A, respectively. As shown in FIGS. 7B, 8B, 9B, and 10B, the first carriage 30 stops at a position P1 to the left of the left end P0 of the ON range of the origin sensor 70 in step S12. The above description of the position of the first carriage 30 is based on the right end of the light-shielding plate 73, and the same applies to the subsequent description indicating the position. Further, when the position is shown by a reference numeral, it also refers to the position where the right end of the shading plate 73 is located.

In step S12, the control device 100 receives the signal of the encoder 23A and stores the temporary origin position TP0 of the first carriage 30. More specifically, the control device 100 sets the temporary origin position TP0 and outputs the encoder 23A at a position where the light-shielding plate 73 passes through the left end P0 of the ON range of the origin sensor 70 and the output of the origin sensor 70 is turned OFF. Remember the value. The tentative origin position TP0 is theoretically the same position as the position P0.

At the start of step S12, the connected state of the first carriage 30 and the second carriage 40 is one of the four patterns shown in FIGS. 7A, 8A, 9A, and 10A. In the first pattern, the first carriage 30 and the second carriage 40 are connected, and the second carriage 40 is fixed by the lock mechanism 60. This state is shown in FIG. 7A. The state shown in FIG. 7A is hereinafter referred to as a first state. The second pattern is a pattern in which the first carriage 30 and the second carriage 40 are connected, and the lock mechanism 60 does not fix the second carriage 40. This state is shown in FIG. 8A. The state shown in FIG. 8A is hereinafter referred to as a second state. In the third pattern, the first carriage 30 and the second carriage 40 are disconnected, and the lock mechanism 60 is a pattern in which the second carriage 40 is fixed. This state is shown in FIG. 9A. The state shown in FIG. 9A is hereinafter referred to as a third state. The fourth pattern is a pattern in which the first carriage 30 and the second carriage 40 are disconnected, and the lock mechanism 60 also does not fix the second carriage 40. This state is shown in FIG. 10A. The state shown in FIG. 10A is hereinafter referred to as a fourth state. The fourth state cannot occur depending on the operation of the print-and-cut device 1, but can occur by human intervention or the like.

In step S12, the first carriage 30 moves in the second main scanning direction Y2 (left) from each state shown in FIGS. 7A, 8A, 9A, and 10A, and the origin sensor 70 is turned off. It stops at the position P1 slightly to the left of. During this movement, the scan motor 23 is driven by a driving force that separates the first carriage 30 from the second carriage 40. This is because the first carriage 30 is separated from the second carriage 40 and moved to the position P1 even if the connected state at the start of step S12 is the first state. When the state at the start of step S12 is the first state, the connection between the first carriage 30 and the second carriage 40 is disconnected, and only the first carriage 30 moves to the position P1 (FIG. 7B). Further, when the state at the start of step S12 is the second state, the first carriage 30 and the second carriage 40 move to the position P1 while being integrated (FIG. 8B). When the state at the start of step S12 is the third state, only the first carriage 30 moves to the position P1 (FIG. 9B). Even when the state at the start of step S12 is the fourth state, only the first carriage 30 moves to the position P1 (FIG. 10B). The conventional print-and-cut device 1 does not know which of the states of FIG. 7B, FIG. 8B, FIG. 9B, and FIG. 10B is the state of the first carriage 30 and the second carriage 40 after step S12, and is in step S12. To complete.

Following step S12, step S13 is executed. In step S13, the first carriage 30 is moved in the first main scanning direction Y1 (to the right) and stops at the temporary origin position TP0 stored in the control device 100. In step S13, in order to ensure the position accuracy of the temporary origin position TP0 with a constant accuracy, the scan motor 23 is driven at a low speed (for example, about 10 mm / sec) commensurate with the accuracy. The positioning accuracy of the temporary origin position TP0 at this time is, for example, about ± 0.2 mm.

After the first carriage 30 is set to the temporary origin position TP0 by step S10 (steps S11 to S13), the step proceeds to step S20. FIG. 11 is a front view showing the states of the first carriage 30 and the second carriage 40 after the end of step S20. In step S20, the first carriage 30 is driven in the first main scanning direction Y1 to the unlock position ULP of the lock mechanism 60. Whether or not the first carriage 30 has moved from the temporary origin position TP0 to the unlocked position ULP is confirmed based on the measurement result of the moving distance by the encoder 23A of the scan motor 23. The connection states of the first carriage 30 and the second carriage 40 started from various initial states are aligned with the second state in step S20. That is, the first carriage 30 and the second carriage 40 are connected to each other, and the second carriage 40 is not fixed by the lock mechanism 60. Even if the first carriage 30 and the second carriage 40 are separated at the start of step S20, they come into contact with each other at some point during movement and are connected by the magnetic force of the connecting mechanism 50. Further, the fixing of the second carriage 40 is released by moving the first carriage 30 and the second carriage 40 to the unlocked position ULP in the connected state. In the middle of step S20, although the first carriage 30 and the second carriage 40 are not stopped, they pass through the lock position LP (first state).

In step S30, the coupling body of the first carriage 30 and the second carriage 40 is moved in the second main scanning direction Y2, and is slightly to the left of the left end P0 of the ON region of the origin sensor 70 (for example, in FIG. 8B). Stop at the indicated position P1). In the following step S40, the coupling body of the first carriage 30 and the second carriage 40 is moved in the first main scanning direction Y1 and stops when the origin sensor 70 is turned on. Subsequently, the coupling body of the first carriage 30 and the second carriage 40 is moved in the second main scanning direction Y2 (leftward) at a lower speed (for example, 1 mm / sec) than that in step S13, and the origin sensor. It is stopped when 70 is turned off. This point is the origin position FP0 of the first carriage 30, and the control device 100 stores the output value of the encoder 23A at the origin position FP0. The origin position FP0 is theoretically the same position as the temporary origin position TP0. However, in reality, the required position accuracy is different from the temporary origin position TP0. The position accuracy of the origin position FP0 is higher than the position accuracy of the temporary origin position TP0, and is, for example, about ± 0.02 mm. The difference in accuracy between the temporary origin position TP0 and the origin position FP0 is caused by the difference in the moving speed of the first carriage 30 at the time of positioning. The slower the moving speed of the first carriage 30 during positioning, the better the positioning accuracy.

In the following step S50, the coupling body of the first carriage 30 and the second carriage 40 is moved in the first main scanning direction Y1 and stopped at the standby position WP. As described above, in the standby position WP, the second carriage 40 is locked by the lock mechanism 60. The standby position WP is one position within the width of the lock position LP. Further, the position accuracy of the standby position WP is equivalent to the position accuracy of the origin position FP0, and is about ± 0.02 mm. In step S50 as well, the first carriage 30 may be slightly (for example, about 1 mm) overshooting the standby position WP and then returned at a low speed. The process of shifting to the standby state by the conventional print-and-cut device 1 is as described above, for example.

As can be seen from the above, steps S10 and S20 in the conventional method are steps for making the connected state of the first carriage 30 and the second carriage 40 constant regardless of the initial state. To put it the other way around, if the initial connection state of the first carriage 30 and the second carriage 40 can be known, the steps S10 and S20 can be omitted in some cases.

(Transition process to standby state: In the case of this embodiment)
The print-and-cut device 1 according to the present embodiment is configured to be able to know whether or not the connected state of the first carriage 30 and the second carriage 40 is in the first state. As shown in FIG. 5, the first connection control unit 104 of the print-and-cut device 1 according to the present embodiment includes a connection determination unit 104A, a connection instruction unit 104B, and a standby instruction unit 104C. The connection determination unit 104A determines whether or not the connection state of the first carriage 30 and the second carriage 40 at the start of the transition to the standby state is in the first state. The first state is a state in which the first carriage 30 and the second carriage 40 are connected and the second carriage 40 is fixed. When the connection determination unit 104A determines that the connection state is a state other than the first state, the connection instruction unit 104B controls the scan motor 23 to put the first carriage 30 and the second carriage 40 into the first state. Let me. The standby instruction unit 104C controls the scan motor 23 to move the first carriage 30 and the second carriage 40 in the first state to the standby position. Hereinafter, the process of shifting to the standby state by the print-and-cut device 1 according to the present embodiment will be described.

FIG. 12 is a flowchart showing a process of shifting to the standby state by the print-and-cut device 1 according to the present embodiment. As shown in FIG. 12, the transition to the standby state by the print-and-cut device 1 according to the present embodiment starts from step S01 for determining the initial state. In step S01, it is determined whether or not the first carriage 30 and the second carriage 40 are in the first state. If the first carriage 30 and the second carriage 40 are in the first state and the result of step S01 is "YES", the step proceeds to step S02. In step S02, the connecting body of the first carriage 30 and the second carriage 40 is slightly moved in the first main scanning direction Y1 and stopped at the unlocked position of the lock mechanism 60. At this point, the same situation as after the end of step S20 in FIG. 6 is achieved. After this, the steps proceed to steps S30, S40, S50. Steps S30 to S50 are the same as in the case of the conventional print and cut apparatus shown in FIG.

As shown in FIG. 12, when the first carriage 30 and the second carriage 40 are in a state other than the first state in step S01 and the result of step S01 is "NO", the step proceeds to step S10. move on. After that, the flow of proceeding to step S20 is the same as that of FIG. 6, and merges with the case where step S01 is "YES" in step S30. The process when the result of step S01 is "NO" is the same as in the conventional case.

As described above, in the print-and-cut device 1 according to the present embodiment, when it is determined that the first carriage 30 and the second carriage 40 are in the first state at the start of the transition to the standby state, the first carriage 30 and the second carriage 40 are in the first state. The work of putting the carriage 30 and the second carriage 40 in the first state (here, steps S10 and S20) is omitted, and in other cases, the work of putting the first carriage 30 and the second carriage 40 in the first state is performed. Run.

The method for determining whether or not the first carriage 30 and the second carriage 40 are in the first state in step S01 is as follows. In step S01, the connection determination unit 104A first controls the scan motor 23 so that the first carriage 30 is moved in the second main scanning direction Y2 by a predetermined distance Dc (movement distance indicated value, see FIG. 14B). This moving distance indicated value Dc is, for example, about 5 mm. Further, at this time, the driving force for driving the scan motor 23 is the connecting force between the first carriage 30 and the second carriage 40 by the connecting mechanism 50 (here, the magnetic force between the first connecting member 51 and the second connecting member 52). ) Is a weaker driving force. Therefore, when the first carriage 30 and the second carriage 40 are connected by the connecting mechanism 50, the scan motor 23 cannot separate the first carriage 30 from the second carriage 40.

13A and 13B are front views showing the first carriage 30 and the second carriage 40 when the initial state is the first state in the determination of the connected state. FIG. 13A shows the initial state, and FIG. 13B shows the state after the determination. 14A and 14B are front views showing the first carriage 30 and the second carriage 40 when the initial state is the second state in the determination of the connected state. The second state is a state in which the first carriage 30 and the second carriage 40 are connected and the second carriage 40 is not fixed. FIG. 14A shows the initial state, and FIG. 14B shows the state after the determination. As shown in FIGS. 13A and 13B, the first carriage 30, which was in the first state in the initial state, starts moving from the position SP1 and moves by a distance Dp. That is, the first carriage 30 moves only the distance Dp even though the scan motor 23 tries to move the movement distance indicated value Dc (see FIG. 14B) in the second main scanning direction Y2 (Dp < Dc). This is because the driving force of the scan motor 23 is weaker than the coupling force of the coupling mechanism 50, and the first carriage 30 cannot be separated from the second carriage 40. In the first state, the second carriage 40 is fixed by the lock mechanism 60 and cannot slide. The distance that the first carriage 30 moves is at most the width of the lock position of the lock mechanism 60, and the distance Dp is less than that. Here, the width of the lock position of the lock mechanism 60 is about 2 mm, which is smaller than the movement distance indicated value Dc (here, 5 mm) that the scan motor 23 is trying to move.

On the other hand, when the initial state is the second state, as shown in FIGS. 14A and 14B, the first carriage 30 starts moving from the position SP2 and the movement distance indicated value Dc commanded by the connection determination unit 104A. It has moved in the second main scanning direction Y2 by the same distance as (Dp = Dc). The driving force of the scan motor 23 is larger than the frictional force between the connecting body of the first carriage 30 and the second carriage 40 and the guide rail 21, and moves the connecting body of the first carriage 30 and the second carriage 40. Can be made to. As shown in FIGS. 13A to 14B, when the initial state is the first state, there is a discrepancy between the movement distance indicated value of the first carriage 30 commanded by the connection determination unit 104A and the actual movement distance. Occurs and does not occur in the second state. Although not shown, in the case where the initial state is the third state and the fourth state, the movement distance instruction value of the first carriage 30 commanded by the connection determination unit 104A and the actual value are the same as in the case of the second state. It matches the travel distance of. That is, only when the initial state is the first state, a discrepancy occurs between the movement distance indicated value of the first carriage 30 commanded by the connection determination unit 104A and the actual movement distance. The actual moving distance is measured by the encoder 23A of the scan motor 23.

The connection determination unit 104A stores the threshold value in the determination in step S01. In the above case, this threshold value is set to 3 mm with respect to, for example, the movement distance indicated value of 5 mm. When the actual moving distance of the first carriage 30 is less than the threshold value, the connection determination unit 104A determines that the connection state of the first carriage 30 and the second carriage 40 is the first state. On the contrary, when the actual moving distance of the first carriage 30 is equal to or greater than the threshold value, the connection determination unit 104A determines that the connection state of the first carriage 30 and the second carriage 40 is a state other than the first state. do. FIG. 15 shows a flowchart for determining the connection state in step S01. As shown in FIG. 15, in the first step S01A, a drive command for the scan motor 23 is issued. In the following step S01B, the actual moving distance of the first carriage 30 is grasped based on the signal from the encoder 23A. In step S01C, the actual moving distance of the first carriage 30 and the preset threshold value are compared. When the actual moving distance of the first carriage 30 is less than the threshold value (in the case of "YES") in step S01C, the initial state of the first carriage 30 and the second carriage 40 is determined to be the first state. At this time, the result of step S01 is "YES". When the actual moving distance of the first carriage 30 is equal to or greater than the threshold value in step S01C (when “NO”), it is determined that the initial states of the first carriage 30 and the second carriage 40 are states other than the first state. Will be done. At this time, the result of step S01 is "NO".

In the above, the threshold value is set to the moving distance of the first carriage 30, but it may be set to the deviation between the moving distance indicated value and the actual moving distance. When the deviation between the movement distance indicated value and the actual movement distance exceeds the threshold value, the connected state is determined to be the first state. When the deviation between the movement distance indicated value and the actual movement distance is equal to or less than the threshold value, it is determined that the connected state is a state other than the first state. Similar to the above example, when the movement distance indicated value is 5 mm and the movement distance in the initial state is the maximum of 2 mm, the threshold value is set to, for example, 2 mm. In this case, when the connected state is the first state, the deviation between the movement distance indicated value and the actual movement distance is between 3 mm and 5 mm, which is larger than the threshold value of 2 mm. When the connected state is a state other than the first state, the deviation between the movement distance indicated value and the actual movement distance is approximately 0 mm, which is smaller than the threshold value of 2 mm.

(Effect of this embodiment)
As described above, the print-and-cut device 1 according to the present embodiment includes the connection determination unit 104A, and determines whether the connection state is the first state or the other state. Specifically, the scan motor 23 is driven by a driving force weaker than the connecting force of the connecting mechanism, and the signal of the encoder 23A of the scan motor 23 is taken in to measure the actual moving distance of the first carriage 30, and the moving distance is measured. When is less than a predetermined value, it is determined that the connected state is the first state. On the contrary, when the moving distance is equal to or more than a predetermined value, it is determined that the connected state is a state other than the first state. According to the print-and-cut device 1 according to the present embodiment, it is possible to confirm the connected state of the first carriage 30 and the second carriage 40.

Further, the print-and-cut device 1 according to the present embodiment includes a connection instruction unit 104B, and when the connection determination unit 104A determines that the connection state is other than the first state, the connection state of the first carriage 30 and the second carriage 40 Is in the first state. Conversely, when the connection determination unit 104A determines that the connection state is the first state, the connection instruction unit 104B omits the process of changing the connection state of the first carriage 30 and the second carriage 40 to the first state. do. Therefore, according to the print-and-cut device 1 according to the present embodiment, the time required to change the connected state of the first carriage 30 and the second carriage 40 to the first state can be shortened.

The effect of shortening the time is particularly remarkable in the print-and-cut device such as the print-and-cut device 1 according to the present embodiment, in which the first carriage 30 is once positioned for the transition to the first state. Positioning of the first carriage 30 requires time to achieve the required accuracy, and according to the print-and-cut device 1 according to the present embodiment, that time can be saved in many cases.

In the print-and-cut device 1 according to the present embodiment, a magnetic force is used to connect the first carriage 30 and the second carriage 40 by the connecting mechanism 50. According to this method, the first carriage 30 and the second carriage 20 are connected. Control of connection and separation with 40 is easy and reliable. At the time of connection, the first carriage 30 may be moved to the side of the second carriage 40 to be brought into contact, and at the time of separation, the connected state is set to the first state, and the scan motor 23 is driven by a driving force stronger than the coupling force due to the magnetic force. Just let me do it. Further, if the scan motor 23 is driven with a driving force weaker than the coupling force due to the magnetic force, the connection is not released, and it is easy to realize the step of determining the connection state.

The preferred embodiment of the present invention has been described above. However, the above embodiments are merely examples, and the present invention can be implemented in various other embodiments.

For example, in the above-described embodiment, the lock mechanism 60 is configured to be unlocked when further pushed from the lock position, but it does not have to be such a mechanism. The locking mechanism may be, for example, a mechanism including a solenoid, in which the engaging member engages with and disengages the second carriage 40 by turning the solenoid on and off. Alternatively, for example, a solenoid that attracts the second carriage 40 with a stronger coupling force than the coupling mechanism 50 when turned on may be provided. The mechanism of the lock mechanism is not limited. The mechanism of the coupling mechanism is also not limited. The connecting mechanism may be any mechanism that can separate the first carriage 30 and the second carriage 40 by the driving force of the scan motor 23, and is not limited to the one provided with a magnet.

In the above embodiment, the first carriage 30 and the second carriage 40 have been moved to the standby position by the process shown in FIG. 12, but the process of FIG. 12 is only an example. The process of arranging the first carriage 30 and the second carriage 40 in the standby position is appropriately set in consideration of the configuration of the connecting mechanism 50 and the lock mechanism 60, the arrangement of the origin sensor 70, the position accuracy required for the standby position, and the like. It's okay. It does not necessarily include the step of confirming the origin position, and various sensors may be appropriately used as the sensor for confirming the origin position. Further, the connection state and the origin position may be confirmed not only for positioning the second carriage 40 in the standby position but also at any time if necessary.

Further, in the above-described embodiment, the determination of the connected state has been described as a pre-step of the step of shifting the first carriage 30 and the second carriage 40 to the first state, but the determination is not limited thereto. The determination of the connected state may be carried out at any time as needed. For example, the determination of the connected state can also be used in a step of confirming the amount of play in the first state when the play of the lock mechanism 60 increases due to aged deterioration or the like.

In the above-described embodiment, the print-and-cut device 1 is configured to move the cutting head 31 and the print head 41 in the main scanning direction Y and convey the medium 200 in the sub-scanning direction X. However, the cutting head 31 and the print head 41 may be configured to be movable not only in the main scanning direction Y but also in the sub-scanning direction X. In that case, the medium 200 may be immobile. Further, in the above-described embodiment, the cutting head 31 is mounted on the first carriage 30 and the print head 41 is mounted on the second carriage 40, but the reverse may be performed. That is, the print head 41 may be the main drive and the cutting head 31 may be the driven drive.

The present invention can be applied to other than the print-and-cut apparatus as described above. The head mounted on the first carriage 30 and the second carriage 40 is not limited to the cutting head and the print head. For example, the head mounted on the first carriage 30 and the second carriage 40 may both be a print head or a cutting head.
