[0003] Patent literature 1: WO2017 / 006382A Summary of the invention; Technical task

[0004] In the device described in patent literature 1, after the opening in the upper part of the cartridge has been inserted into the cylindrical air supply area, the hollow, disc-shaped clamping area is rotated to adapt and secure the clamping area to the bottom section of the cartridge. Therefore, the structure becomes complex, and attaching and removing the cartridge is time-consuming and labor-intensive.

[0005] The purpose of this disclosure is to further simplify the insertion and removal of the cartridge. Solution to the problem

[0006] The present disclosure uses the following means to achieve the goal described above.

[0007] The present disclosure relates to a viscous liquid feeder installed in a printing press, wherein the viscous liquid feeder serves to supply viscous liquids used for printing, and wherein the viscous liquid feeder comprises the following: a holder with an opening through which a cartridge containing the viscous fluid can be inserted and removed, and a mounting section to which the cartridge is attached by pressing the cartridge horizontally from the opening backwards; and a first air supply area which is arranged at the mounting receiving area such that the first air supply area is connected to the cartridge in a state in which the cartridge is attached to the mounting receiving area and which is configured to supply first air to the cartridge in order to discharge the viscous fluid from the cartridge.

[0008] In the viscous liquid feed device of the present disclosure, the cartridge can be attached to the holder and the first air supply area simultaneously connected to the cartridge by simply pushing the cartridge horizontally backwards from the opening. This further facilitates the attachment and removal of the cartridge.

[0009] The present disclosure relates to a cartridge that can be detachably attached to a printing machine, wherein the cartridge serves to hold viscous liquid used for printing, and wherein the cartridge comprises the following: a cylindrical cup with a bottom, designed to hold the viscous liquid; a sliding element arranged so that it can slide on an inner circumferential surface of the cup and has an outlet opening; and A housing comprising an element configured to receive the cup and the sliding element with a gap on an inner circumferential side and having an air inlet for introducing air to discharge the viscous liquid in the cup from the outlet opening, wherein the air inlet is arranged on a side surface of the housing, identification information that can be read by a reader is arranged on a bottom surface of the cup, and at least one section of the housing corresponding to the identification information is formed from a transparent element.

[0010] In the cartridge of the present disclosure, the identification information is arranged on the bottom surface of the cup, and at least one section of the housing that receives the cup corresponding to the identification information is formed from a transparent element.

[0011] In the following, an embodiment of the present disclosure is described with reference to the accompanying figures.

[0012] Fig. Figure 1 is a perspective view of a printing press 10. Fig. Figure 2 is a top view of printing press 10. Fig. Figure 3 is a partial exterior view of the front of printing press 10. Fig. Figure 4 is a perspective view of the plumb line feeder 40. Fig. Figure 5 is a partially enlarged view of a holding section 42 of the solder feed device 40. Fig. Figure 6 is an external perspective view of cartridge 60. In the Fig. 1, Fig. 2, Fig. 3 to Fig. 4. The left-right direction is called the X-axis, the front-back direction the Y-axis, and the top-bottom direction the Z-axis.

[0013] The printing machine 10 of the present embodiment is a machine that prints solder paste onto the plate S located below the screen mask M via pattern holes by pressing the solder paste onto the screen mask M with a squeegee 22 into the pattern holes formed in the screen mask M. The printing machine 10, in combination with a component assembler that mounts an electronic component onto the plate S onto which solder paste has been printed, forms a production line.

[0014] As in Fig. As shown in Figure 1, the printing machine 10 comprises a printing machine main body 11, a housing 12 that accommodates the printing machine main body 11, and a control device (not shown) that controls the entire printing machine. The printing machine main body 11 comprises a head device 20, a plate feeder 30, and a solder feeder 40 as the feeder for viscous liquid in the present embodiment.

[0015] As in Fig. As shown in Figure 3, a window 13 is arranged on a front side of the housing 12, which can be opened and closed by means of a door (sliding door) 14.

[0016] The head device 20 is installed in an upper section of the printing press main body 11. As shown in the Fig. 1 and Fig. As shown in Figure 2, the head device 20 comprises a head body 21 and a head movement section 26, which moves the head body 21 in the front-to-back direction (Y-axis direction), which is a pressure direction. The head movement section 26 comprises a guide rail 28 extending in the front-to-back direction (Y-axis direction), a Y-axis slider 27 moving along the guide rail 28, and a slider drive section (not shown) that drives the Y-axis slider 27. For example, a slider drive section with a ball screw mechanism and a motor or a slider drive section with a linear motor is used. The head body 21 includes a pair of front and rear doctor blades 22 and a doctor blade lifting and lowering section (not shown) which is configured, for example, with an air cylinder and raises and lowers the corresponding doctor blade 22.The pair of squeegees 22 are plate-shaped elements that extend orthogonally to the printing direction in the left-right direction (X-axis direction) and are inclined in such a way that the pair of squeegees 22 are separated from each other towards the underside when viewed in the left-right direction.

[0017] The plate conveyor 30 is installed in a lower part of the main body of the printing press 11. The plate conveyor 30 comprises a conveying device (not shown) that conveys the plate S by means of a conveyor belt.

[0018] The solder feed device 40 holds a cylindrical cartridge 60 containing solder and feeds the solder from the cartridge 60 onto the screen mask M. As shown in Fig. As shown in Figure 1, the solder feed device 40 comprises a holder 41 which holds the cartridge 60 releasably, and a holder movement section 46 which moves the holder 41 in the left-right direction (X-axis direction).

[0019] The holder movement section 46 comprises a guide rail 47, which is arranged on the Y-axis slider 27 to extend in the left-right direction (X-axis direction), an X-axis slider 48 that moves along the guide rail 47, and a slider drive section (not shown) that drives the X-axis slider 48. For example, a slider drive section with a ball screw mechanism and a motor or a slider drive section with a linear motor is used as the slider drive section. The holder 41 is moved by the head movement section 26 and the holder movement section 46 in the forward-backward and left-right directions.

[0020] As in Fig. As shown in Figure 4, the holder 41 is a box-shaped element with an opening 41a on the front and a vertically through hole 41b on the underside. The door 14 opens when the holder 41 has moved in front of the window 13 of the housing 12, allowing a worker to attach and remove the cartridge 60 from the front of the housing 12, as shown in Figure 4. Fig. 3 shown.

[0021] As in Fig. As shown in Figure 4, the holder 41 is provided with a holding section 42, a connection receiving section 50, a seat sensor 54, residual quantity sensors 55 and 56 and a reading section 57.

[0022] As in the Fig. 4 and Fig. As shown in Figure 5, the retaining section 42 is arranged and positioned around the through-hole 41b and holds the cartridge 60 on the through-hole 41b. In the present embodiment, several (two) through-holes 41b and retaining sections 42 are arranged in the lower part of the holder 41 in a left-right orientation, and the holder 41 can hold several (two) cartridges 60. Accordingly, several cartridges 60, containing different types of solder, are pre-loaded into the holder 41, thus saving time and effort in replacing the cartridge 60 when the type of solder to be supplied is changed. The holder 41 can also hold only one cartridge 60.

[0023] The holding section 42 comprises a press-receiving section 43, which is arranged on the rear side of the holder 41 with respect to the through-hole 41b, a front guide section 44, which is arranged on the lower part of the holder 41 and on the front side of the holder 41 with respect to the through-hole 41b, and lateral guide sections 45, which are arranged on the lower part of the holder 41 and on both sides of the through-hole 41b. The press-receiving section 43 is a section against which the cartridge 60, which is inserted from the opening 41a of the holder 41 in the front-to-back direction (Y-axis direction), is pressed. In the present embodiment, press-receiving sections 43 are arranged at two locations, and a connecting receiving section 50 is arranged between the press-receiving sections 43. The front guide section 44 is designed in an inclined shape that rises from front to back.The guide sections 45 are band-shaped elements that extend longitudinally and guide the cartridge 60 from both sides. When the cartridge 60 is inserted longitudinally backward from the opening 41a of the holder 41, it is pressed against the press-receiving sections 43 while being guided by the guide sections 45. The cartridge 60 is inserted into a step between the lower part of the holder 41 and the end of the incline of the front guide section 44 while being pressed against the press-receiving sections 43, so that the cartridge 60 is positioned by the press-receiving sections 43, the front guide section 44, and the lateral guide sections 45.

[0024] As in Fig. As shown in Figure 5, the connection-receiving section 50 comprises a forward-projecting engagement pin 51, a plumb-in air supply opening 52 arranged on a first of the left and right sides of the engagement pin 51, a plumb-out air supply opening 53 arranged on a second of the left and right sides of the engagement pin 51, and a seat sensor 54 that detects the insertion of the cartridge 60. In the present embodiment, the seat sensor 54 is configured as an optical sensor comprising a light projection section and a light reception section arranged opposite each other at a predetermined distance. The seat sensor 54 can be configured with a proximity sensor or the like.

[0025] The residual quantity sensors 55 and 56 are arranged on a rear surface section of the holder 41. These sensors are, for example, optical and detect a residual quantity of solder in the cup 61 by sensing the position of the cup 61 that holds the solder. The residual quantity sensors 55 and 56 are mounted at different heights on the holder 41. In the present embodiment, residual quantity sensor 55 is mounted at a position slightly lower than that of residual quantity sensor 56, so that residual quantity sensor 55 detects that no residual quantity of solder is present, and residual quantity sensor 56 detects that the residual quantity of solder is small. The residual quantity sensors 55 and 56 can detect the residual quantity of solder by sensing the weight of the cartridge 60.

[0026] As in Fig. As shown in Figure 6, the cartridge 60 comprises a cup 61, a lid element 62, a housing 70, and a connecting section 80. The cup 61 is a cylindrical element with an open bottom and holds the solder. An identification code 65 (e.g., a QR code (registered trademark), a barcode, or similar) for identifying the type of solder held is attached to the bottom of the cup 61. A reading section 57 for reading the identification code 65 is arranged on an upper section of the holder 41 to face the identification code 65, which is attached to the bottom of the cup 61 when the cartridge 60 is mounted on the holder 41 (holding area 42).

[0027] A lid element 62 is a disc-shaped element that is in sliding contact with the inner circumferential surface of the cup 61. The underside of the lid element 62 is connected to a discharge tube 63, which has a cylindrical shape with an open bottom and is essentially the same height as the cup 61. A vertical through-hole 62a is formed in a central section of the lid element 62, and a vertical through-hole 63a is formed in a central section of a bottom surface of the discharge tube 63. The lid element 62 and the discharge tube 63 are connected to each other such that the through-holes 62a and 63a are interconnected.

[0028] The housing 70 comprises a lower housing 71 with a cylindrical shape, a base, and an open top, an upper housing 72 with a cylindrical shape, a base, and an open bottom, and a connecting element 73 that connects the lower housing 71 and the upper housing 72 in a state where their openings are in contact. A connecting section 80 and a wrench-sized section 71c are arranged on the outer circumferential surface of the lower housing 71. The wrench-sized section 71c is designed to have a width slightly smaller than the width between the pair of guide sections 45 and is formed at a position (chamfer) where, in a state where the connecting section 80 faces the connecting receiving section 50 on the outer circumferential surface of the lower housing 71, the wrench-sized section 71c comes into sliding contact with the guide sections 45.This allows the worker to attach the cartridge 60 (connecting section 80) to the holder 41 (connecting receiving section 50) simply by aligning the phases so that the wrench-width section 71c is guided by the guide sections 45 and pressing in the cartridge 60.

[0029] The through-hole 71a is formed in a central section of a bottom surface (underside) of the lower housing 71. The lower end face of the discharge tube 63 is attached to the bottom surface of the lower housing 71 to communicate with the through-hole 71a. Therefore, the solder in the cup 61 is discharged from the through-hole 62a of the lid element 62 to the outside through the discharge tube 63 and the through-hole 71a of the lower housing 71.

[0030] The housing 70 (lower housing 71 and upper housing 72) is designed such that its inner circumferential surface has a gap in the radial direction with respect to the outer circumferential surface of the cup 61 or the discharge tube 63. In the present embodiment, the upper housing 72 is formed from a transparent element (e.g., acrylic or polycarbonate) so that the identification code 65 attached to the underside of the cup 61 can be read by the reading section 57. In the upper housing 72, at least one section corresponding to the underside (top) of the cup 61 can be formed from a transparent element.

[0031] The connecting section 80 comprises an engagement hole 81, a solder supply air inlet 82, a solder discharge air inlet 83, and a detection element 84. The engagement hole 81, the solder supply air inlet 82, the solder discharge air inlet 83, and the detection element 84 are arranged at positions corresponding to the engagement pin 51, the solder supply air inlet 52, the solder discharge air inlet 53, and the seat sensor 54, respectively, when the connecting section 80 and the connecting receiving section 50 are opposite each other. When the connecting section 80 is connected to the connecting receiving section 50, the engagement pin 51 engages in the engagement hole 81, and the cartridge 60 is mounted (positioned) on the holder 41. At the same time, the plumb supply air inlet 52 is connected to the plumb supply air inlet 82 to supply plumb supply air, and the plumb discharge air inlet 53 is connected to the plumb discharge air inlet 83 to supply plumb discharge air.Since the detection element 84 blocks the light emission section and the light reception section of the seat sensor 54 (optical sensor), the seat sensor 54 detects that the cartridge 60 is inserted (installed). Accordingly, the solder feed device 40 can supply the solder from the cartridge 60 after it has been verified that the cartridge 60 is installed.

[0032] The soldering air is supplied from the soldering air inlet 82, which is located on the side surface of the cartridge 60 (lower housing 71). Since there is a gap between the outer circumferential surfaces of the discharge tube 63 and the cup 61 and the inner circumferential surface of the housing 70 (lower housing 71, upper housing 72 and connecting element 73), and between the bottom surface of the cup 61 and the bottom surface of the upper housing 72, the soldering air is introduced into this gap. Due to a difference in the pressure-bearing surface between the opening side and the bottom surface of the cup 61, a differential pressure is created (see Fig. 7). Accordingly, the cup 61 is pressed downwards in relation to the lid element 62 (see Fig. 8) The soldering medium in the cup 61 is then discharged to the outside in this sequence through the through-hole 62a, the discharge tube 63, and the through-hole 71a. Furthermore, the remaining quantity of soldering medium in the cup 61 is detected by the residual quantity sensors 55 and 56 according to the position of the cup 61.

[0033] The soldering air is supplied through the soldering air inlet 83, which is located on the side surface of the cartridge 60 (lower housing 71). Air channels 71b and 63b for the soldering air are formed in the lower housing 71 and in the discharge tube 63, which is attached to the lower housing 71. An annular groove 63c is formed in an inner circumferential section of the through-hole 63a of the discharge tube 63, which communicates with the through-hole 62a of the cover element 62. The soldering air, which has flowed through the air channels 71b and 63b, is supplied to the annular groove 63c and expelled radially inwards from the annular groove 63c. This results in, as shown in Fig. Figure 10 shows that the solder hanging from the through-hole 62a is carried away by the high-pressure air. Therefore, it is prevented that, after the solder has been fed from the cartridge 60 onto the screen mask M, the remaining solder remains hanging down and falls to a location other than the screen mask M.

[0034] When the cartridge 60 is not in use, it is stored in a housing 70 on a shelf or similar in a warehouse. When the cartridge 60 is in use, the worker takes the cartridge 60 from the shelf and mounts it on the solder feed device 40 (holder 41) of the printing press 10. As described above, the identification code 65 is affixed to the bottom of the cup 61, and the upper housing 72, which covers the cup 61, is made of a transparent element. Therefore, the worker can, as described in Fig.Figure 11 shows that even if several cartridges 60 are arranged close together on the shelf or similar in the warehouse, the identification code 65 can be easily read using the code reader 100. This allows the worker to easily find the cartridge 60 containing the required type of solder when needed.

[0035] Here, a correspondence relationship between the main elements of the embodiment and the main elements of the present disclosure, as described in the claims, is described. That is, the solder feed device 40 of the present embodiment corresponds to a feed device for viscous liquids of the present disclosure, the cartridge 60 corresponds to a cartridge, the connection receiving section 50 corresponds to a mounting receiving section, the holder 41 corresponds to a holder, and the solder feed air supply opening 52 corresponds to a first air supply. The cup 61 corresponds to a cup, the cover element 62 corresponds to a sliding element, and the lower housing 71, the upper housing 72, and the connecting element 73 correspond to a housing. The solder discharge air supply opening 53 corresponds to a second air supply area. The reading section 57 corresponds to a reading section. The side guide section 45 corresponds to a guide section.The seat sensor 54 corresponds to an assembly detection section.

[0036] It goes without saying that the present disclosure is in no way limited to the embodiment described above and can therefore be implemented in various aspects, as long as these aspects fall within the technical scope of the present disclosure.

[0037] For example, in the embodiment described above, the holder 41 has a solder removal air supply opening 53 and the cartridge 60 has a solder removal air inlet 83, but these elements can also be omitted.

[0038] In the embodiment described above, the identification code 65 is attached to the underside of the cup 61, and the upper housing 72 is formed from a transparent element so that the identification code 65 can be read from above the housing 70. However, the identification code 65 can also be attached to the side surface (outer circumferential surface) of the cup 61. The identification code 65 can also be attached to the housing 70.

[0039] In the embodiment described above, the solder feed device (solder feed device 40) supplies the solder as a viscous liquid to the printing machine 10, and the printing machine 10 prints the solder onto the plate S as the target. However, the viscous liquid can also be a conductive paste or an adhesive, and the target can be another plate, for example, a three-dimensional object.

[0040] In the embodiment described above, the operator attaches the cartridge 60 to the holder 41 of the solder feed device 40. However, the printing machine 10 can include a cartridge storage area for holding multiple cartridges 60 and an automatic exchange device for automatically exchanging the cartridge 60 between the cartridge storage area and the holder 41. Since the cartridge 60 can be easily attached to the holder 41 by pushing it horizontally backward, the configuration of the automatic exchange device can be further simplified.

[0041] As described above, in the viscous liquid feed device of the present disclosure, the cartridge can be attached to the holder and the first air supply area can be connected to the cartridge simultaneously by simply pushing the cartridge backwards horizontally from the opening. This further simplifies the attachment and removal of the cartridge.

[0042] In the viscous liquid feeding device according to the present disclosure, the cartridge can comprise a cylindrical cup with a bottom designed to receive the viscous liquid, a sliding element arranged to slide on an inner circumferential surface of the cup and having an outlet opening, and a housing designed to receive the cup and the sliding element with a gap on an inner circumferential side, and the first air supply area can supply first air from a side surface of the housing to the gap, and the viscous liquid can be dispensed from the outlet opening by moving the cup relative to the sliding element by a differential pressure corresponding to a pressure-bearing area difference between a bottom surface side and an opening side of the cup.With this configuration, the device can be made more compact than in a case where the initial air is supplied from the top of the housing.

[0043] In this case, the viscous fluid feed device can further comprise a second air supply section, arranged in the mounting receptacle and configured to supply a second air supply for the removal of the viscous fluid ejected from the outlet opening, with a passage for the second air being formed in the sliding element in the direction of the outlet opening. This prevents the remaining viscous fluid from accumulating and falling to a location other than the feed position after the fluid has been fed.

[0044] In these cases, the viscous liquid feed device may further include a reading section configured to read identification information, wherein the identification information is located on the underside of the cup, at least a portion of the housing corresponding to the identification information is formed from a transparent element, and the reading section is positioned such that the underside of the cup is contained within a reading area when the cartridge is attached to the receiving section. With this configuration, the printing press can detect information on the solder medium by attaching the cartridge to the holder.

[0045] In the viscous liquid feeding device of the present disclosure, the holder can include a guide section configured to guide the horizontal movement of the cartridge. This configuration can further facilitate the attachment and removal of the cartridge.

[0046] The viscous liquid feeding device of the present disclosure may further comprise an attachment detection section arranged on the attachment receiving section and configured to detect whether the cartridge is attached to the attachment receiving section. In this way, the cartridge can be attached more reliably.

[0047] Furthermore, in the viscous liquid feeding device of the present disclosure, the holder can be configured such that several cartridges can be mounted in an arranged manner in a direction that is horizontal and orthogonal to the insertion and removal direction of the cartridge. With this configuration, several cartridges containing different types of solder are pre-accommodated in the holder, thus saving time and effort in changing cartridges, even when the type of solder being fed is changed.

[0048] In the present disclosure, the form of the feeding device for viscous liquids is used, but the form of a cartridge can also be used. In the cartridge of the present disclosure, the identification information is indicated on the bottom of the cup, and at least a part of the housing that receives the cup corresponding to the identification information consists of a transparent element. Therefore, the identification information can be easily read by the reader from outside the housing.
