[Figure 8] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a cell device of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

[0008] Fig. 1 is a front view showing a cell device according to a preferred embodiment. Fig. 2 is a front view showing the cell device with the door open. Fig. 3 is a cross-sectional view showing the inside of the mounting table. Fig. 4 is a top view of the mounting table. Fig. 5 is a front view of the mounting table. Fig. 6 is a top view of the cell device. Figs. 7 and 8 are cross-sectional views of the hand.

[0009] In addition, each figure except for Figures 7 and 8 shows three mutually orthogonal axes: the X-axis, the Y-axis, and the Z-axis. Hereinafter, the direction along the X-axis will be referred to as the X-axis direction, the direction along the Y-axis will be referred to as the Y-axis direction, and the direction along the Z-axis will be referred to as the Z-axis direction. The arrow side of each axis will also be referred to as the "plus side," and the side opposite the arrow will be referred to as the "minus side." The positive side of the Z-axis direction will also be referred to as the "upper," and the negative side will be referred to as the "lower."

[0010] The cell apparatus 1 shown in FIG. 1 has a housing 2, a robot 5 and an injection molding machine 6 as movable devices installed in the housing 2, and a control device 9 that controls the driving of the robot 5 and the injection molding machine 6.

[0011] <Case 2> 1, the housing 2 has a first housing unit 3 and a second housing unit 4 connected to the first housing unit 3 on the negative side in the X-axis direction. The second housing unit 4 is detachable from the first housing unit 3, and is connected to the first housing unit 3 using various metal fittings such as bolts. Although not shown, the housing 2 is provided with wheels and stoppers, and the cell device 1 can be moved to an arbitrary installation location using the wheels and fixed to the location using the stoppers.

[0012] As shown in FIG. 1, the first housing unit 3 has a base 31, a cover member 32 arranged on the upper side of the base 31, a first storage space S1 as a storage space defined by the cover member 32, and a door 33 attached to the cover member 32 so as to be freely opened and closed. The robot 5 is stored in the first storage space S1. In this embodiment, the side walls located on both sides of the cover member 32 in the X-axis direction are removed for convenience of the operation of the robot 5, but this is not limited thereto, and at least one side in the X-axis direction may be closed by a side wall according to the operation of the robot 5. In addition, the first housing unit 3 is provided with a sensor (not shown) that detects the opening and closing of the door 33. If the door 33 is opened during the operation of the cell device 1, the cell device 1 is stopped in an emergency for safety reasons.

[0013] The base 31 also has a second housing space S2 formed inside thereof. Therefore, the second housing space S2 is located below the first housing space S1. The control device 9 is housed in the second housing space S2.

[0014] The door 33 is disposed on the front side of the cover member 32 and is connected to the first storage space S1. Therefore, a user can access the first storage space S1 by opening the door 33. The door 33 is a single-wing door that opens outward. An opening / closing axis J of the door 33 is provided at the end on the positive side in the X-axis direction. The door 33 has a frame-shaped frame 331 as a light-shielding part, a window part 332 as a light-transmitting part attached to the inside of the frame 331, and a handle 333 attached to the frame 331. The handle 333 is attached to the end on the negative side in the X-axis direction, which is opposite to the opening / closing axis J. This allows the door 33 to be opened and closed with less force.

[0015] The frame 331 has a light-shielding property. Therefore, when the door 33 is closed, the frame 331 can conceal necessary parts of the first storage space S1. In other words, it can be made invisible to the user. On the other hand, the window portion 332 has a light-transmitting property. Therefore, even when the door 33 is closed, the first storage space S1, particularly the robot 5, can be visually observed through the window portion 332. Therefore, the state of the robot 5 can be monitored during the operation of the cell device 1. For example, the frame 331 is made of various metal materials such as aluminum and stainless steel, and the window portion 332 is made of a light-transmitting material such as transparent glass and transparent plastic.

[0016] As shown in FIG. 2, the first housing unit 3 is disposed in the first storage space S1 and has a mounting table 34 on which the robot 5 is placed. The mounting table 34 has a mounting portion 341 disposed at a distance from the upper surface of the base 31 and a frame-shaped side wall 342 surrounding the four sides of a space S11 formed between the mounting portion 341 and the base 31. The robot 5 is placed on the mounting portion 341. As shown in FIG. 3, a wiring group LG including at least one wiring L that electrically connects the robot 5 and the control device 9 is accommodated in the space S11 in the mounting table 34. In this way, by accommodating the wiring group LG in the mounting table 34, the wiring group LG can be routed while avoiding the working area of ​​the robot 5 located above the mounting table 34. Therefore, the wiring group LG is less likely to be exposed in the working area of ​​the robot 5, and the risk of the wiring group LG interfering with the robot 5 is reduced. This realizes stable operation of the cell device 1. In particular, in this embodiment, since the side wall 342 surrounds the entire periphery of the space S11, the wiring L is less likely to protrude outside the mounting table 34, and the above-mentioned effect becomes more pronounced. However, without being limited thereto, a part of the side wall 342 may be missing, and a part of the space S11 may be opened to the outside from that part.

[0017] 2, the first housing unit 3 further has an interlock device 39 which is a safety device that regulates the opening and closing of the door 33. The interlock device 39 is disposed on a front portion 342a of a side wall 342 of the mounting table 34, that is, on a portion of the side wall 342 facing the door 33. With this arrangement, the interlock device 39 can be disposed outside the working area of ​​the robot 5, reducing the possibility that the interlock device 39 will interfere with the robot 5. Also, a larger working area for the robot 5 can be secured accordingly.

[0018] The interlock device 39 has an electromagnet 391. When the current flowing through the electromagnet 391 is increased while the door 33 is closed, the door 33 is firmly attracted to the electromagnet 391, and the door 33 is locked. In this state, the door 33 cannot be opened. On the other hand, when the current flowing through the electromagnet 391 is decreased or the current supply to the electromagnet 391 is stopped, the door 33 is unlocked and the door 33 can be opened. In the cell device 1, the door 33 is locked while the cell device 1 is operating normally, and is unlocked when it is necessary to open the door 33, such as when the cell device 1 is stopped normally or when an emergency stop occurs due to an abnormality. This can improve the safety of the cell device 1. However, the configuration of the interlock device 39, the timing of unlocking, and the like are not particularly limited.

[0019] It is preferable that the interlock device 39 is disposed near the handle 333. Therefore, in this embodiment, the interlock device 39 is disposed at the end portion on the negative side in the X-axis direction of the front surface portion 342a. This makes it possible to suppress the stress applied to the door 33 due to the attraction force of the electromagnet 391 when the door 33 is opened, and effectively suppresses damage and deformation of the door 33. However, the location of the interlock device 39 is not particularly limited.

[0020] Here, we return to the description of the door 33. As described above, the door 33 has a frame 331 in the shape of a frame. As shown in Figs. 4 and 5, the frame 331 is arranged so as to overlap the mounting table 34 when the cell device 1 is viewed from the front side (the door 33 side) with the door 33 closed. That is, the front part 342a of the mounting table 34 and the frame 331 face each other. With the door 33 closed, the inner surface of the frame 331 comes into contact with the electromagnet 391. Therefore, as described above, by forming the frame 331 from a metal material, in particular, a magnetic material, the door 33 can be locked more reliably and firmly.

[0021] Furthermore, since the frame 331 has a light-shielding property, the front portion 342a is concealed by the door 33 when the door 33 is closed. Therefore, by disposing the interlock device 39 on the front portion 342a, which is the concealed portion, the interlock device 39 can be made invisible to the user while the cell device 1 is in operation. The interlock device 39 is a device that is not used by the user except for inspection, maintenance, etc., that is, during normal operation. Therefore, by concealing the interlock device 39 with the door 33, it is possible to reduce unnecessary information that comes into the user's field of vision. As a result, the user can concentrate more on working with the cell device 1.

[0022] In particular, in this embodiment, when the cell device 1 is viewed from the front side (door 33 side) with the door 33 closed, the frame 331 is disposed so as to overlap with the entire side wall 342. Therefore, wherever the interlock device 39 is disposed within the front portion 342a, it is concealed by the frame 331, so that the design freedom of the arrangement of the interlock device 39 is increased. However, this is not limited thereto, and at least a part of the side wall 342 may not overlap with the frame 331 and may be visible through the window portion 332.

[0023] The above has described the first housing unit 3. Next, the second housing unit 4 will be described. As shown in Fig. 1, the second housing unit 4 has a base 41. Unlike the first housing unit 3 described above, the second housing unit 4 does not have a cover member on the upper side of the base 41, and the space above the base 41 is open.

[0024] Although the housing 2 has been described above, the housing 2 is not particularly limited. For example, depending on the configuration of the cell device 1, the second housing unit 4 may be omitted. Also, at least one housing unit may be further connected to the negative side in the X-axis direction of the second housing unit 4. Also, at least one housing unit may be further connected to the positive side in the X-axis direction of the first housing unit 3. Also, the second housing unit 4 may be provided with a cover member similar to that of the first housing unit 3 to define an accommodation space for accommodating the injection molding machine 6. Also, the door 33 is not limited to a hinged door, and may be, for example, a sliding door, a folding door, or the like.

[0025] <Injection molding machine 6> As shown in Fig. 1, the injection molding machine 6 is mounted on the second housing unit 4. The injection molding machine 6 molds a molded product MD from a resin material. As shown in Figs. 1 and 6, the injection molding machine 6 is a vertical injection molding machine, and has a material storage section 61 that stores a resin material, a molding die 62 that includes an upper molding die 621 and a lower molding die 622 and defines a cavity according to the shape of the molded product MD, an injection unit 63 that melts the resin material stored in the material storage section 61 and injects it into the molding die 62, and a movement mechanism 64 that moves the lower molding die 622.

[0026] The injection unit 63 is fixed to the base 41 of the second housing unit 4 via a plurality of support columns 65. The material storage section 61 is disposed above the injection unit 63, and the upper molding die 621 is disposed below the injection unit 63. The lower molding die 622 is disposed below the upper molding die 621, and the molding die 62 opens and closes as the lower molding die 622 moves up and down (Z-axis direction) relative to the upper molding die 621. The lower molding die 622 that has moved downward is moved back and forth (Y-axis direction) by the movement mechanism 64. In the following, the case where the molding die 62 is opened and the lower molding die 622 is located directly below the upper molding die 621 is also referred to as a first state, and the state where the lower molding die 622 has moved forward (Y-axis minus side) from the first state (the state shown in FIG. 6) is also referred to as a second state.

[0027] Such an injection molding machine 6 is driven as follows. First, the mold 62 is closed. Next, the injection unit 63 injects a molten resin material into the mold 62. This fills the cavity of the mold 62 with the resin material. The resin material in the cavity is cooled and hardened to obtain a molded product MD. Next, the mold 62 is opened to set the lower mold 622 in the first state, and the moving mechanism 64 moves the lower mold 622 forward to set the second state. Then, a pin (not shown) arranged in the lower mold 622 pushes the molded product MD in the lower mold 622 upward, thereby releasing the molded product MD from the lower mold 622. The molded product MD released in this manner is held by the robot 5 and transported to a predetermined position.

[0028] Although the injection molding machine 6 has been described above, the injection molding machine 6 is not particularly limited as long as it is capable of molding a molded product MD.

[0029] <Robot 5> 2, the robot 5 is disposed in the first accommodation space S1, and is placed on the placement portion 341 of the placement table 34. By placing the robot 5 on the placement portion 341, the placement table 34 functions as a spacer, and the robot 5 can be installed at a desired height relative to the injection molding machine 6. In other words, the height of the placement table 34 is determined so that the robot 5 is at a desired height relative to the injection molding machine 6.

[0030] The robot 5 also grips a molded product MD molded by the injection molding machine 6 and transports it to a predetermined position. The robot 5 is a SCARA robot (horizontally articulated robot) and has a base 50 fixed to the placement unit 341, a first arm 51 that rotates around the Z axis relative to the base 50, a second arm 52 that rotates around the Z axis relative to the first arm 51, and a spline shaft 53 that is disposed at the tip of the second arm 52 and extends in the Z axis direction. The spline shaft 53 is rotatable around its central axis relative to the second arm 52 and is movable up and down along the central axis. A hand 54 that grips the molded product MD is attached to the lower end of the spline shaft 53.

[0031] Although not particularly limited, when the distance between the mounting portion 341 of the mounting table 34 and the upper end of the first housing space S1 is D1 and the height of the robot 5 is D2, it is preferable that D1 / D2 is 1.1 or more and 1.3 or less. By setting such dimensions, it is possible to keep the overall height of the housing 2 low while ensuring a sufficient working area for the robot 5. Furthermore, by keeping the overall height of the housing 2 low, it is possible to reduce the size of the cell device 1 and improve maintainability.

[0032] The hand 54 is not particularly limited as long as it can grip the molded product MD, and in this embodiment, it is a translation type air chuck that is driven by using compressed air (hereinafter, also referred to as "air") as a fluid. As shown in Figs. 7 and 8, such a hand 54 has an air cylinder 540 having a body 541 and a piston 542 that protrudes / retracts from the body 541, a pair of claws 544a, 544b that open and close along a guide provided on the body 541, and a pair of levers 545a, 545b that are located between the piston 542 and the claws 544a, 544b and transmit the movement of the piston 542 to the claws 544a, 544b. In addition, the body 541 is formed with a rod side air intake port 541a that communicates with a space on the rod side of the piston 542, and a head side air intake port 541b that communicates with a space on the head side of the piston 542.

[0033] The rod-side air intake port 541a is connected to the solenoid valve 72 via the first air pipe 71a, and the head-side air intake port 541b is connected to the solenoid valve 72 via the second air pipe 71b. Although not shown, the solenoid valve 72 is connected to a compressed air supply device such as a compressor installed in a factory or the like via a regulator. The solenoid valve 72 can switch the air supply direction. As shown in FIG. 7, when air is supplied from the rod-side air intake port 541a and discharged from the head-side air intake port 541b, the piston 542 retreats into the body 541 and the claws 544a and 544b close, and the molded product MD can be gripped. Conversely, as shown in FIG. 8, when air is supplied from the head side air intake port 541b and exhausted from the rod side air intake port 541a, the piston 542 protrudes from the body 541, the claw portions 544a, 544b open, and the molded product MD can be released.

[0034] In addition, a first speed controller 73a for adjusting the air flow rate is disposed in the first air pipe 71a, and a second speed controller 73b for adjusting the air flow rate is disposed in the second air pipe 71b. By adjusting the air flow rate with the first and second speed controllers 73a and 73b, the moving speed of the piston 542, that is, the opening and closing speed of the claws 544a and 544b, can be adjusted.

[0035] 4 and 5, the solenoid valve 72 has a lever-type switch 721 that is a switching unit for switching the air supply direction. For example, if the robot 5 makes an emergency stop while holding the molded product MD, it is necessary to remove the molded product MD from the robot 5 for recovery work. In this case, the molded product MD can be easily removed by operating the switch 721 to reverse the air flow in the hand 54 and open the claws 544a and 544b. However, the configuration of the switching unit is not particularly limited, and may be a button type, a slide type, a dial type, a touch panel type, or the like.

[0036] The first speed controller 73a also has a screw-type (dial-type) knob 731a as a fluid speed adjustment unit that adjusts the flow speed of air flowing through the first air pipe 71a. The more the screw-type knob 731a is tightened, the more the tip of the knob 731a protrudes into the first air pipe 71a and blocks the inside of the pipe, thereby decreasing the flow speed of the air. Similarly to the first speed controller 73a, the second speed controller 73b also has a screw-type knob 731b as a fluid speed adjustment unit that adjusts the flow speed of air flowing through the second air pipe 71b. However, the configuration of the fluid speed adjustment unit is not particularly limited, and may be a lever type, a button type, a touch panel type, or the like.

[0037] In the following description, the switch 721 and the knobs 731a and 731b are collectively referred to as "operation unit 70."

[0038] As shown in Figs. 4 and 5, the operation unit 70 is disposed on the mounting table 34 within the first accommodation space S1. By disposing the operation unit 70 on the mounting table 34 in this way, the operation unit 70 can be disposed outside the working area of ​​the robot 5, reducing the risk of the operation unit 70 interfering with the robot 5. In addition, the user's body is less likely to collide with the robot 5 while operating the operation unit 70, which increases the safety of the cell device 1 and also suppresses breakdowns in the robot 5. In addition, by disposing the operation unit 70 outside the working area of ​​the robot 5, a larger working area for the robot 5 can be secured.

[0039] In particular, the operation unit 70 is disposed on the front surface 342a of the mounting base 34. That is, the operation unit 70 is disposed facing the door 33. According to such an arrangement, when the door 33 is opened, the operation unit 70 appears in front, so that the operation unit 70 can be easily operated. In particular, as described above, the frame 331 is disposed so as to overlap with the entire side wall 342, so that the entire operation unit 70 is concealed by the frame 331 no matter where the operation unit 70 is disposed within the front surface 342a. Therefore, the design freedom of the arrangement of the operation unit 70 is increased. Furthermore, the operation unit 70 is disposed closer to the door 33 than the robot 5, that is, on the front surface side. According to such an arrangement, the operation unit 70 can be approached without being obstructed by the robot 5, so that the operation unit 70 can be easily operated.

[0040] In this way, by disposing the operation unit 70 on the front portion 342a of the mounting table 34, the operation unit 70 can be hidden by the door 33, similar to the above-mentioned interlock device 39. Therefore, it is possible to reduce unnecessary information that comes into the user's field of vision during normal operation. As a result, the user can concentrate more on working with the cell device 1. In addition, since the operation unit 70 can be covered by the door 33, it is possible to effectively prevent the user from erroneously operating the operation unit 70 during normal operation.

[0041] In particular, the switch 721 and the knobs 731a and 731b included in the operation unit 70 are not used except for inspection, adjustment, maintenance, and recovery work from an emergency stop. Specifically, the switch 721 is mainly used with the door 33 open when the robot 5 is restored from an emergency stop. The knobs 731a and 731b are mainly used with the door 33 open when the robot 5 is adjusted before operation. Therefore, the switch 721 and the knobs 731a and 731b are used only with the door 33 open, and are not used with the door 33 closed. Therefore, even if the switch 721 and the knobs 731a and 731b are arranged in the first accommodation space S1 and covered with the door 33, opening and closing the door 33 does not complicate the operation of the operation unit 70. Therefore, it is possible to suppress erroneous operation of the operation unit 70 without sacrificing usability.

[0042] In this embodiment, the operation unit 70 includes the switch 721 and the knobs 731a and 731b, but the configuration of the operation unit 70 is not particularly limited as long as it is not operated when the door 33 is closed, but is operated when the door 33 is open. For example, a main power button of the cell device 1 may be included in addition to the above. In addition, the entire operation unit 70 does not necessarily need to overlap with the light-shielding part, and it is sufficient that at least a part of the operation unit 70 overlaps with the light-shielding part and is hidden to the extent that the user cannot visually recognize the operation unit 70. In addition, the light-shielding part has a light-shielding property to the extent that the user cannot visually recognize the operation unit 70.

[0043] <Control device 9> As shown in Fig. 1, the control device 9 is disposed in the second housing space S2 of the first housing unit 3. The control device 9 controls the driving of the injection molding machine 6 and the robot 5 in a coordinated manner. Such a control device 9 is, for example, composed of a computer, and has a processor (CPU) for processing information, a memory communicatively connected to the processor, and an external interface for connecting to an external device. Various programs executable by the processor are stored in the memory, and the processor can read and execute the various programs stored in the memory.

[0044] In particular, the control device 9 is electrically connected to the robot 5 via a wire L housed in the mounting table 34, as shown in Fig. 3. Therefore, by disposing the control device 9 below the mounting table 34, it becomes easy to connect the wire L to the control device 9. Also, the length of the wire L can be shortened.

[0045] The cell device 1 has been described above. As described above, the cell device 1 includes the housing 2 having the first housing space S1, which is a housing space, and the door 33 connected to the first housing space S1, the robot 5, which is a movable device disposed in the first housing space S1, and the operation unit 70, which is disposed in the first housing space S1 and operates the robot 5. The door 33 also includes a frame 331, which is a light-shielding portion having light-shielding properties, and a window portion 332, which is a light-transmitting portion having light-transmitting properties. When the housing 2 is viewed from the door 33 side with the door 33 closed, the frame 331 overlaps with the operation unit 70. According to this configuration, the operation unit 70 is hidden and does not enter the user's field of vision during operation of the cell device 1. Therefore, it is possible to reduce unnecessary information that enters the user's field of vision. As a result, the user can concentrate more on the work using the cell device 1. In addition, since the operation unit 70 can be covered by the door 33, it is possible to effectively suppress erroneous operation of the operation unit 70 by the user.

[0046] As described above, the operation unit 70 is not operated when the door 33 is closed, but is operated when the door 33 is open. In this way, the operation unit 70, which is operated only when the door 33 is open, i.e., there is no opportunity to operate it, is disposed in the first accommodation space S1 and covered by the door 33, so that opening and closing of the door 33 does not complicate the operation of the operation unit 70. Therefore, it is possible to suppress erroneous operation of the operation unit 70 without sacrificing usability.

[0047] As described above, the operation unit 70 is disposed in the first storage space S1 facing the door 33. With this configuration, when the door 33 is opened, the operation unit 70 appears in front, making it easy to operate the operation unit 70.

[0048] As described above, the operation unit 70 is disposed closer to the door 33 than the robot 5, that is, on the front side. With this configuration, the operation unit 70 can be easily approached and operated.

[0049] As described above, the housing 2 is disposed in the first storage space S1 and has the mounting table 34 on which the robot 5 is placed. The operation unit 70 is disposed on the side wall 342 of the mounting table 34. With this configuration, the operation unit 70 can be disposed outside the working area of ​​the robot 5, reducing the possibility that the operation unit 70 will interfere with the robot 5. In addition, the user's body is less likely to collide with the robot 5 while operating the operation unit 70, which increases the safety of the cell device 1 and also suppresses breakdowns in the robot 5. In addition, by disposing the operation unit 70 outside the working area of ​​the robot 5, a larger working area for the robot 5 can be secured.

[0050] As described above, when the housing 2 is viewed from the door 33 side with the door 33 closed, the frame 331 overlaps the entire side wall 342. This allows the operation unit 70 to be hidden by the frame 331 no matter where the operation unit 70 is placed on the side wall 342, increasing the freedom of placement of the operation unit 70.

[0051] As described above, the operation unit 70 includes knobs 731a, 731b as fluid speed adjustment units that adjust the speed of compressed air, which is a fluid supplied to the robot 5. Such knobs 731a, 731b are used with the door 33 open when adjusting the robot 5 before operation, and are not used during normal operation, that is, with the door 33 closed. For this reason, the knobs 731a, 731b are suitable for the operation unit 70, and by covering the knobs 731a, 731b with the door 33, malfunction of the knobs 731a, 731b can be suppressed.

[0052] As described above, the operation unit 70 includes the switch 721 as a switching unit that switches the supply direction of compressed air supplied to the robot 5. Such a switch 721 is used with the door 33 open when the robot 5 is restored from an emergency stop, and is not used during normal operation, that is, with the door 33 closed. Therefore, the switch 721 is suitable for the operation unit 70, and by covering the switch 721 with the door 33, it is possible to suppress malfunction of the switch 721.

[0053] As described above, the cell device 1 is disposed in the first storage space S1 and has an interlock device 39 that regulates the opening and closing of the door 33. When the door 33 is closed and the housing 2 is viewed from the door 33 side, the frame 331 overlaps with the interlock device 39. With this configuration, the interlock device 39 is hidden and out of the user's field of vision while the cell device 1 is in operation. This reduces unnecessary information that enters the user's field of vision. As a result, the user can concentrate more on working with the cell device 1.

[0054] Although the cell device of the present invention has been described above based on the illustrated embodiment, the present invention is not limited thereto, and the configuration of each part can be replaced with any configuration having a similar function. In addition, any other configuration may be added to the present invention. [Explanation of symbols]
