[0004] Patent Document 1: International Publication No. 2022 / 234649 Summary of the Invention

[0005] Problems to be Solved by the Invention

[0006] In the above-described working device, since the conveyance object on the support rail is pushed forward and backward by the push rod for conveyance, after the push rod stops when the conveyance object moves to the target position, the conveyance object also advances beyond the target position due to inertia, and sometimes the conveyance object cannot be positioned at the target position.

[0007] The main object of the present disclosure is to more reliably position a conveyance object at a predetermined position in a device that conveys the conveyance object on a track by pushing with a pressing member.

[0008] Means for Solving the Problems

[0009] The present disclosure adopts the following means to achieve the above main object.

[0010] The conveying device of the present disclosure includes a pair of tracks extending in parallel along the horizontal direction, and conveys and positions a conveyance object used in a production line at a predetermined position on the pair of tracks. The conveying device includes:

[0011] A pressing member having an adsorption portion that adsorbs to the adsorbed portion of the conveyance object on a surface orthogonal to the extending direction of the track;

[0012] A lifting portion that lifts and lowers the pressing member;

[0013] A moving portion that moves the pressing member along the extending direction of the pair of tracks;

[0014] A clamping part that clamps the object to be conveyed on the pair of tracks relative to the pair of tracks; and

[0015] A control part that controls the lifting part and the moving part to lower the pressing member so that the adsorption part of the pressing member adsorbs to the adsorbed part of the object to be conveyed, controls the moving part to convey the object to be conveyed to the predetermined position, and after controlling the clamping part to clamp the object to be conveyed at the predetermined position, controls the lifting part and the moving part to retract the pressing member from the object to be conveyed.

[0016] In the conveying device of the present disclosure, after adsorbing the object to be conveyed (adsorbed part) to the pressing member (adsorption part), the object to be conveyed is pushed by the pressing member and conveyed to the predetermined position, and after clamping the object to be conveyed at the predetermined position, the pressing member is retracted from the object to be conveyed. Thereby, the object to be conveyed can be positioned at the predetermined position more reliably.

[0017] The conveying method of the present disclosure uses a pressing member and a pair of tracks extending parallel to each other in the horizontal direction to convey and position the object to be conveyed used in the production line on the pair of tracks. The conveying method includes the following steps:

[0018] Making the pressing member adsorb to the object to be conveyed on a plane orthogonal to the extending direction of the track,

[0019] Moving the pressing member along the extending direction of the pair of tracks to convey the object to be conveyed to the predetermined position,

[0020] After clamping the object to be conveyed at the predetermined position, retracting the pressing member from the object to be conveyed.

[0021] In the conveying method of the present disclosure, the same effect as the conveying device of the present disclosure can be achieved. Description of the Drawings

[0035] Next, a mode for implementing the present disclosure will be described with reference to the accompanying drawings.

Figure 7 It is a block diagram showing the electrical connection relationship of the printing machine. In Figures 1 - 6 the left - right direction is set as the X - axis, the front - rear direction is set as the Y - axis, and the up - down direction is set as the Z - axis.

[0037] The printing machine 10 of the present embodiment presses the solder paste on the screen mask M into the pattern holes formed in the screen mask M by using the squeegee 22, and prints the solder paste onto the substrate S below through the pattern holes. The printing machine 10 is combined with a component mounter that mounts electronic components on the substrate S printed with solder to form a production line. Moreover, when changing the type of the substrate S to be produced, the printing machine 10 can automatically replace the screen mask M and the substrate support member 32 that supports the substrate S according to the type of the substrate S.

[0038] As Figure 1 、 Figure 2 shown, the printing machine 10 includes: a printing machine main body 11, a housing 12 that houses the printing machine main body 11, a replacement device 50, a housing bracket 60, and a control device 100 that controls the entire printing machine (refer to Figure 7 ). The printing machine main body 11 has: a head device 20, a substrate conveying device 30, an identification unit 35, and a conveying track 40.

[0039] The head device 20 is provided at the upper stage part of the printing machine main body 11. As Figure 1 shown, the head device 20 includes a head main body 21 and a head moving part 26 that moves the head main body 21 in the front-rear direction (Y-axis direction) as the printing direction. The head moving part 26 has: a guide rail 28 that extends in the front-rear direction, a Y-axis slider 27 that moves along the guide rail 28, a motor 29a that drives the Y-axis slider 27, and a position sensor (encoder) 29b that detects the position of the head main body 21. As Figure 2 shown, the head main body 21 has: a pair of front and rear squeegees 22; a pair of squeegee lifting parts 23, for example, constituted by air cylinders and lifting the corresponding squeegee 22; a push rod 24; and a push rod lifting part 25, for example, constituted by an air cylinder and lifting the push rod 24. The pair of front and rear squeegees 22 are plate-shaped members that extend in the left-right direction (X-axis direction) orthogonal to the printing direction, and are inclined so as to separate from each other as they approach the lower side when viewed from the left-right direction. As Figure 3 shown, the push rod 24 has a pair of front and rear and left and right first pressing parts 24a having abutting surfaces formed on a surface orthogonal to the front-rear direction (Y-axis direction) and a pair of left and right second pressing parts 24b having abutting surfaces formed below. A pair of left and right conveying tracks 40 that extend in the front-rear direction are provided at the middle stage part of the printing machine main body 11. In a state where the push rod 24 is lowered by the push rod lifting part 25, the push rod 24 moves back and forth through the head moving part 26, thereby pushing the replacement frames 70, 80 on the conveying track 40 back and forth to move them. As Figure 2 shown, the replacement frames 70, 80 move in and out of the housing 12 through a through hole 38 provided at the middle stage part of the front surface of the housing 12. In addition, a detection sensor 39 for detecting the passage of the replacement frames 70, 80 is provided at the through hole 38.

[0040] The substrate conveying device 30 is provided at the lower layer part of the printing machine main body 11. The substrate conveying device 30 carries in and positions and supports the substrate S, and brings the substrate S into contact with and separates it from the screen mask M (back surface). As Figure 2As shown in the figure, the substrate transfer device 30 includes: a substrate transfer unit 31 that transfers a substrate S in the left-right direction (X-axis direction); a substrate support member 32 that supports the substrate S transferred by the substrate transfer unit 31 from below; a lift table 34 on which the substrate support member 32 is placed; and a substrate support member lift unit 33 that lifts and lowers the substrate support member 32 together with the lift table 34. The substrate support member 32 is replaced with a substrate support member 32 having a size suitable for supporting the substrate S according to the type of the substrate S.

[0041] The identification unit 35 identifies the substrate S and the substrate support member 32. As Figure 1 shown in the figure, the identification unit 35 includes a camera body 36 and a camera moving unit 37 that moves the camera body 36. The identification unit 35 reads a mark attached to the upper surface of the substrate S to identify the position of the substrate S when the substrate S is transferred and positioned by the substrate transfer device 30. In addition, when the replacement frame 80 is transferred and positioned on the transfer track 40, the identification unit 35 reads a mark attached to the substrate support member 32 held by the replacement frame 80 to identify the position and size of the substrate support member 32.

[0042] The replacement device 50 uses the replacement frames 70 and 80 to receive the storage bracket 60 that houses the replacement parts (the screen mask M or the substrate support member 32) used in the printing machine main body 11, and transfers the replacement parts between the storage bracket 60 and the printing machine main body 11. As Figure 1 shown in the figure, the replacement device 50 includes a left unit 51a provided on the left side of the front surface (front side) of the printing machine main body 11 and a right unit 51b provided on the right side of the front surface of the printing machine main body 11. The left unit 51a and the right unit 51b have a bracket support member 52 that receives the storage bracket 60 and supports its lower surface from both left and right sides, and a bracket lift unit 53 that lifts and lowers the bracket support member 52. The bracket lift unit 53 is constituted by, for example, a combination of a ball screw mechanism and a motor or a linear electric mechanism. The storage bracket 60 supported by the bracket support member 52 is lifted and lowered together with the bracket support member 52 by the bracket lift unit 53. Moreover, the left unit 51a and the right unit 51b have a frame front-rear movement unit 54 that transports the replacement frames 70 and 80 in the storage bracket 60 from both left and right sides to the front and rear using a belt or rollers.

[0043] As Figure 1As shown, the accommodation bracket 60 is a housing body that has a multi-layered pair of left and right support rails 61 vertically and can accommodate replacement parts (replacement frames 70, 80) in each support rail 61. Openings 62, 63 are formed on the front surface of the accommodation bracket 60 on the side opposite to the printing press main body 11 and on the back surface on the side of the printing press main body 11. The replacement parts (replacement frames 70, 80) are put in and taken out by an operator or the like through the opening 62 on the front surface side, and are moved in and out of the printing press main body 11 via the opening 63 on the back surface side by the frame forward and backward movement unit 54. In a state where the accommodation bracket 60 is received by the replacement device 50, the frame forward and backward movement unit 54 sends out the replacement part supported by the support rail 61 of the multi-layered support rails 61 of the accommodation bracket 60, which is supported by the bracket lifting unit 53 at a height substantially the same as that of the conveying rail 40 of the printing press main body 11, to the printing press main body 11. In addition, the frame forward and backward movement unit 54 sends the replacement part supported by the conveying rail 40 of the printing press main body 11 into the support rail 61 of the accommodation bracket 60 at a height substantially the same as that of the conveying rail 40. In addition, the accommodation bracket 60 can be transported by an operator to the receiving position of the replacement device 50, or can be mounted on an automatic transport device (AGV) and automatically transported to the receiving position of the replacement device 50 by the automatic transport device.

[0044] The replacement frame 70 is a frame body that supports the printing screen mask M. The printing screen mask M is a thin metal plate and is supported by the replacement frame 70 in a state where a predetermined tension is applied. The printing screen mask M is positioned and fixed at the working position on the conveying rail 40 while being supported by the replacement frame 70 for printing.

[0045] As Figure 4 shown, the replacement frame 80 is a frame body that supports the substrate support member 32 and has substantially the same left and right width as the replacement frame 70. The replacement frame 80 includes a rectangular outer frame 81 and a pair of support arms 82. The pair of support arms 82 are mounted on the outer frame 81 with their front ends facing each other, and the substrate support member 32 is supported from both sides by the front ends. The base end portion of one support arm 82 is disposed near the left side portion 81a of the outer frame 81 and is rotatably supported by a rotation shaft 83 parallel to the left side portion 81a. The base end portion of the other support arm 82 is disposed near the right side portion 81b of the outer frame 81 and is rotatably supported by a rotation shaft parallel to the right side portion 81b. The pair of support arms 82 are urged by a spring to a horizontal posture to support the substrate support member 32 in a horizontal posture. In addition, the pair of left and right support arms 82 are pressed downward by the push rod 24 and spread downward, thereby releasing the support of the substrate support member 32. As described above, a pair of left and right second pressing portions 24b are provided on the push rod 24 (refer to Figure 3), the push rod 24 descends via the push rod lifting part 25 above a pair of support arms 82, and thereby presses down on this pair of support arms 82 using a pair of second pressing parts 24b.

[0046] In addition, in the present embodiment, as Figure 4 shown, the replacement frame 80 includes a cam follower 84 and a magnet member 85. A plurality (for example, five) of cam followers 84 are respectively mounted on the lower surfaces of the left side portion 81a and the right side portion 81b of the outer frame 81 in such a manner that the replacement frame 80 can roll on the conveying track 40.

[0047] In the present embodiment, the magnet member 85 is formed of a permanent magnet and is mounted on the inner surface of the side portion 81c of the outer frame 81 that is orthogonal to the left side portion 81a and the right side portion 81b. The side portion 81c is the front side portion in the direction from the housing bracket 60 toward the upper side of the lifting table 34 among the two side portions of the outer frame 81 that are perpendicular to the left side portion 81a and the right side portion 81b. And, the inner surface of the side portion 81c is the surface to be abutted against which the first pressing part 24a of the push rod 24 abuts when the replacement frame 80 is pushed back and forth by the first pressing part 24a of the push rod 24 for conveyance. The first pressing part 24a of the push rod 24 is formed of a magnetic body. Therefore, by bringing the first pressing part 24a close to the magnet member 85, the push rod 24 is attracted to the replacement frame 80 due to the magnetic attraction of this magnet member 85.

[0048] As Figure 2 shown, the conveying track 40 is a pair of left and right long tracks provided on the fixed table 43 so as to be at substantially the same height as the through hole 38 in the middle section of the printing machine main body 11 and extending in the front-rear direction (Y-axis direction). As Figure 5 , Figure 6 shown, the conveying track 40 includes a pair of left and right first conveying surfaces 41 and a pair of left and right second conveying surfaces 42 provided at a position inside and lower than the pair of left and right first conveying surfaces 41. The pair of left and right first conveying surfaces 41 are for the conveyance of the replacement frame 70 (screen mask M) and support this replacement frame 70 in a horizontal posture. The pair of left and right second conveying surfaces 42 are for the conveyance of the replacement frame 80 (substrate support member 32) and support this replacement frame 80 in a horizontal posture. As described above, cam followers 84 are mounted on the lower surfaces of the left side portion 81a and the right side portion 81b of the outer frame 81 of the replacement frame 80, and the replacement frame 80 travels on the second conveying surface 42 by rolling on the second conveying surface 42 via the cam followers 84.

[0049] In addition, above a pair of left and right conveying rails 40, a plurality of (for example, three) clamping parts 45 for clamping the replacement frame 70 (screen mask M) or the replacement frame 80 (substrate support member 32) are provided along each of the conveying rails 40. Each clamping part 45 has an abutting part 46 and a lifting part 47 (such as a cylinder) provided on the fixed table 43 and for lifting and lowering the abutting part 46. In a state where the replacement frames 70 and 80 are located on the conveying rails 40, each clamping part 45 lowers the abutting part 46, so that the replacement frames 70 and 80 are pressed and clamped to the conveying rails 40 by the abutting part 46.

[0050] As Figure 7 shown, the control device 100 is configured as a microprocessor centered on the CPU 101, and in addition to the CPU 101, it also includes a ROM 102, a RAM 103, and a storage device 104. The control device 100 exchanges signals with the head device 20, the substrate conveying device 30, the recognition part 35, the clamping part 45, and the replacement device 50. In addition, the control device 100 is communicably connected to a management device 200 that manages the production line including the printing machine 10.

[0051] Next, the operation of the printing machine 10 configured as described above, especially the operation of conveying and replacing the screen mask M or the substrate support member 32 together with the replacement frames 70 and 80 during changeover adjustment, will be described. Here, the conveying rails 40, the push rod 24, the push rod lifting part 25, and the head moving part 26 of the present embodiment are examples of the conveying device of the present disclosure.

[0052] The replacement of the screen mask M is performed as follows. That is, the CPU 101 of the control device 100 first controls the push rod lifting part 25 and the head moving part 26, and uses the push rod 24 to push the replacement frame 70 on the first conveying surface 41 that supports the used screen mask M to move it on the first conveying surface 41, and carry out the replacement frame 70 out of the housing 12 from the through port 38. Next, the CPU 101 controls the replacement device 50 to recycle the replacement frame 70 to the storage bracket 60. Next, the CPU 101 controls the replacement device 50 to take out the replacement frame 70 supporting the new screen mask M from the storage bracket 60 and carry it into the housing 12 from the through port 38. And the CPU 101 controls the push rod lifting part 25 and the head moving part 26, and uses the push rod 24 to push the carried-in replacement frame 70 to move it on the first conveying surface 41, thereby conveying the replacement frame 70 (new screen mask M) to the working position and positioning it.

[0053] In addition, the control device 100 also replaces the substrate support member 32 according to the type of the produced substrate S. Figure 8It is a flowchart showing an example of a substrate support member replacement process executed by the CPU 101 of the control device 100. The substrate support member replacement process is performed after retracting the screen mask M (replacement frame 70) on the transfer track 40 to the storage bracket 60 and recycling the used substrate support member 32 placed on the lift table 34 to the storage bracket 60. In addition, the recycling of the used substrate support member 32 is performed as follows. That is, the CPU 101 takes out the empty replacement frame 80 that does not support the substrate support member 32 from the storage bracket 60 and transports it into the housing 12 through the through port 38. Next, the CPU 101 controls the push rod lifting part 25 and the head moving part 26, and uses the push rod 24 to push the transported empty replacement frame 80 to move on the second transfer surface 42, so as to transport the empty replacement frame 80 to the stop position (above the lift table 34) and position it. Next, the CPU 101 transfers the used substrate support member 32 placed on the lift table 34 to the empty replacement frame 80. The transfer of the substrate support member 32 from the lift table 34 to the replacement frame 80 is performed as follows. The CPU 101 controls the push rod lifting part 25, and uses a pair of second pressing parts 24b of the push rod 24 to press a pair of support arms 82 to expand the pair of support arms 82. Next, the CPU 101 controls the substrate support member lifting part 33 to raise the lift table 34 (used substrate support member 32) so that the used substrate support member 32 enters between the pair of support arms 82. And the CPU 101 controls the push rod lifting part 25 to raise the push rod 24, releasing the pressing of the pair of second pressing parts 24b on the pair of support arms 82. Thus, the used substrate support member 32 is supported by the pair of support arms 82. After the CPU 101 supports the used substrate support member 32 on the replacement frame 80, it controls the push rod lifting part 25 and the head moving part 26, and uses the push rod 24 to push the replacement frame 80 to move on the second transfer surface 42, so as to carry it out of the housing 12 from the through port 38. And the CPU 101 controls the replacement device 50 to recycle the replacement frame 80 to the storage bracket 60.

[0054] Hereinafter, with reference to Figures 9 - 13 the substrate support member replacement process will be described.

[0055] In the substrate support member loading process, the CPU 101 of the control device 100 first controls the replacement device 50 to take out the replacement frame 80 supporting the new substrate support member 32 from the storage bracket 60 and transport it into the housing 12 through the through port 38 (S100). Next, the CPU 101 controls the push rod lifting part 25 and the head moving part 26, and moves the push rod 24 in such a way that the first pressing part 24a of the push rod 24 adsorbs to the magnet member 85 of the loaded replacement frame 80 (S110, refer to Figure 9). Next, the CPU 101 controls the head moving unit 26 to push the replacement frame 80 using the first pressing portion 24a of the push rod 24 to move it on the second conveying surface 42, thereby conveying the replacement frame 80 (the new substrate support member 32) (S120, refer to Figure 10 ). And, the CPU 101 determines whether the replacement frame 80 has reached the stop position (above the lifting table 34) based on the signal from the position sensor 29b (S130).

[0056] When the CPU 101 determines that the replacement frame 80 has reached the stop position (refer to Figure 11 ), after stopping the movement of the push rod 24 based on the head moving unit 26, it controls the clamping unit 45 to lower the abutting portion 46, thereby pressing the replacement frame 80 against the second conveying surface 42 using the abutting portion 46 for clamping (refer to S140, Figure 12 ). After clamping the replacement frame 80, the CPU 101 controls the push rod lifting unit 25 and the head moving unit 26 to move (retract) the push rod 24 so that the first pressing portion 24a disengages from the magnet member 85 of the replacement frame 80 (S150, refer to Figure 13 ).

[0057] In this way, after the CPU 101 adsorbs the magnet member 85 of the replacement frame 80 to the first pressing portion 24a of the push rod 24, it uses the push rod 24 to push the replacement frame 80 and convey it to the stop position. After clamping the replacement frame 80 at the stop position, it retracts the push rod 24 from the replacement frame 80. Thereby, after stopping pushing the replacement frame 80 using the push rod 24, it is also possible to prevent the replacement frame 80 from moving due to inertia, and the replacement frame 80 (substrate support member 32) can be more reliably positioned at the stop position. Therefore, it is possible to more reliably perform the subsequent reading of the mark of the substrate support member 32 and the handover of the substrate support member 32.

[0058] Next, the CPU 101 controls the camera moving unit 37 to move the camera body 36 to a predetermined recognition position, and at this recognition position, the camera body 36 is used to read the mark attached to the substrate support member 32 supported by the replacement frame 80 (S160). And when the reading is successful, the CPU 101 transfers the substrate support member 32 from the replacement frame 80 to the lifting table 34 (S170), returns the empty replacement frame 80 to the storage bracket 60 (S180), and ends the substrate support member replacement process. The transfer of the substrate support member 32 from the replacement frame 80 to the lifting table 34 is performed in the following manner: in a state where the lifting table 34 is raised by controlling the substrate support member lifting unit 33, above the lifting table 34, a pair of support arms 82 are pressed down by a pair of second pressing portions 24b of the push rod 24 to release the support of the pair of support arms 82 on the substrate support member 32. In addition, the recovery of the empty replacement frame 80 is performed in the following manner: controlling the push rod lifting unit 25 and the head moving unit 26, using the push rod 24 to push the empty replacement frame 80 to move it on the second conveying surface 42, so as to carry it out of the housing 12 from the through port 38, and controlling the replacement device 50 to return the empty replacement frame 80 to the storage bracket 60.

[0059] Here, the correspondence between the main elements of the embodiment and the main elements of the present disclosure described in the claims will be described. That is, the conveying track 40 (second conveying surface 42) of the present embodiment is an example of the track of the present disclosure, the replacement frame 80 (substrate support member 32) is an example of the object to be conveyed, the push rod 24 is an example of the pressing member, the push rod lifting unit 25 is an example of the lifting unit, the head moving unit 26 is an example of the moving unit, the clamping unit 45 is an example of the clamping unit, and the control device 100 is an example of the control unit. In addition, the cam follower 84 is an example of the roller.

[0060] In addition, it goes without saying that the present disclosure is not limited by any of the above embodiments, and can be implemented in various ways as long as it belongs to the technical scope of the present disclosure.

[0061] For example, in the above embodiment, a magnet member 85 is provided on the replacement frame 80, and the first pressing portion 24a of the push rod 24 is formed of a magnetic body. However, a magnet member may also be provided on the first pressing portion 24a of the push rod 24, and the surface in contact with the first pressing portion 24a of the replacement frame 80 is formed of a magnetic body.

[0062] In the above embodiment, the replacement frame 80 is conveyed by rolling on the second conveying surface 42 through the cam follower 84 provided on its outer frame 81. However, the cam follower 84 may also be omitted, and the replacement frame 80 is conveyed by sliding on the second conveying surface 42.

[0063] In the above-described embodiment, the second conveyance surface 42 is used to convey the replacement frame 80 on which the substrate support member 32 is mounted. However, the second conveyance surface 42 may be used as long as it is used in the printing machine 10, and may also be used to convey a replacement frame on which a replacement member other than the screen mask M (for example, the squeegee 22) is mounted. In addition, regarding the transfer of the squeegee 22 as a replacement member to the head main body 21 when the squeegee 22 is mounted on the replacement frame and conveyed on the second conveyance surface 42, for example, the method described in International Publication No. 2018 / 105016 can be used.

[0064] In the above-described embodiment, the first pressing portion 24a of the push rod 24 adsorbs to the replacement frame 80 which is a frame supporting the substrate support member 32, and pushes the replacement frame 80 to convey the replacement frame 80. However, the first pressing portion 24a of the push rod 24 may also adsorb to the replacement frame 70 which is a frame supporting the screen mask M, and push the replacement frame 70 to convey the replacement frame 70. In this case, a magnet member may also be installed on the inner surface of the front end side in the direction from the housing bracket 60 toward the working position of the two side portions of the outer frame of the replacement frame 70 that are orthogonal to the left side portion and the right side portion. Alternatively, when a magnet member is provided on the first pressing portion 24a of the push rod 24, the surface that abuts against the first pressing portion 24a of the replacement frame 70 may also be formed of a magnetic material.

[0065] In the above-described embodiment, the conveyance device of the present disclosure has been described as being applied to the printing machine 10. However, as long as it is a device for conveying components used in a conveyance production line, it may also be applied to any other working device.

[0066] As described above, in the conveyance device of the present disclosure, after the object to be conveyed (adsorbed portion) is adsorbed to the pressing member (adsorbing portion), the pressing member is used to push the object to be conveyed and convey it to a predetermined position. After the object to be conveyed is clamped at the predetermined position, the pressing member is retracted from the object to be conveyed. Thereby, the object to be conveyed can be more reliably positioned at the predetermined position.

[0067] In such a conveyance device of the present disclosure, it may be that the adsorbing portion of the above-described pressing member is one of a magnet and a magnetic material, and the adsorbed portion of the object to be conveyed is the other of a magnet and a magnetic material. In this way, the pressing member can be disassembled and assembled with respect to the object to be conveyed using a simple structure.

[0068] In addition, in the conveyance device of the present disclosure, it may be that the object to be conveyed has rollers that roll on the above-described track. In this way, the object to be conveyed on the track can be conveyed smoothly, and the object to be conveyed can be more reliably positioned at a predetermined position.

[0069] In the present disclosure, in addition to being configured in the form of a conveying device, it can also be configured in the form of a conveying method or a printing machine.

[0070] Industrial Applicability

[0071] The present disclosure can be used in the manufacturing industry of conveying devices and the like.
