As shown in FIG. 10, the control unit 70 has a function of selecting a number of rollers 2 every time the rollers 2 make a round and injecting lubricating oil into the selected rollers 2. Further, the controller 70 selects a large number of rollers 2 every predetermined number of intervals each time the rollers 2 make a round, and selects each roller 2 to which lubricating oil is first injected every time the rollers 2 make a round. Thus, the selected roller 2 has a function of injecting lubricating oil.
[0028]
Specifically, the control unit 70 is realized by functions of a CPU of a computer, functions of various sensors, and the like. As shown in FIG. 10, a predetermined number setting means 71 for setting a predetermined number of rollers 2 to which lubricating oil is to be injected is selected every predetermined number of intervals, and an optical for detecting the roller 2 reaching the lubricating area. A detecting means 72 such as a sensor, a counting means 73 for counting the number of rollers 2 detected by the detecting means 72 with reference to the specific roller 2 when the detecting means 72 detects one specific roller 2; Based on the count value of the means 73, the lubricating oil is selected for every predetermined number of intervals, and when the specific roller 2 makes a round and the detecting means 72 detects the specific roller 2 again, the lubricating oil is first supplied. And an execution means 74 for injecting the lubricating oil by shifting the roller 2 to be injected one by one.
A mark that can be detected by the detecting means 72 is attached to one specific roller 2.
[0029]
Further, the control unit 70 includes a one-cycle number-of-cycles storage unit 75 that stores the number of cycles of one cycle in which the lubricating oil has been injected into all the rollers 2, a suspension period setting unit 76 that sets a suspension period for each cycle, Based on the count value of the counting means 73, a 1-cycle determining means 77 for determining whether or not the 1-cycle circulation number storage means 75 has reached the 1-cycle circulation number, and a 1-cycle determining means 77 for 1 cycle. An execution control means 78 for stopping the function of the execution means 74 during the pause period set in the pause period setting means 76 and causing the execution means 74 to function when the set pause period of the pause period setting means 76 ends. It is prepared for. For example, when the predetermined number of the predetermined number setting unit 71 is 0, the execution unit 74 makes one cycle determination unit 77 1 when the specific roller 2 makes a round and the detection unit 72 detects the specific roller 2 again. Judge as a cycle. When the predetermined number of the predetermined number setting means 71 is 1, the execution means 74 makes one cycle determination means 77 one cycle when the specific roller 2 makes two revolutions and the detection means 72 detects the specific roller 2 again. Judge.
[0030]
The rest period set in the rest period setting means 76 may be set by any parameter such as time or a count value of the machine operation (for example, the number of circulations of the roller 2). In the case of time, the pause period setting means 76 is set by a timer, for example, and in the case of a count value, it is set by a counter.
[0031]
Further, the number of laps for calculating the number of laps for one cycle in which the lubricating oil is injected into all the rollers 2 from the total number of the rollers 2 counted by the control unit 70 and the counting unit 73 and the predetermined number set in the predetermined number setting unit 71. The calculation means 79 is provided.
Furthermore, the control unit 70 includes various sensors, and includes various means for detecting an abnormality based on the detection of these sensors.
[0032]
Therefore, according to the lubrication apparatus S for a moving body circulation apparatus according to this embodiment, the controller 70 previously skips a predetermined number of rollers 2 to which lubricating oil is to be injected into the predetermined number setting means 71, at a predetermined number interval. The predetermined number selected every time is set. For example, 0 is set when the roller 2 is continuously injected, 1 is set when every other roller 2 is injected, and 2 is set when every other roller 2 is injected. Thereby, the operation mode is set.
In this case, in the case of continuous injection when the interval between the rollers 2 is short, there may be a problem that the capturing body 26 and the injection nozzle body 30 interfere with the next roller 2. Since a predetermined number of injections can be set to be injected, it is possible to deal with rollers 2 at every interval. The predetermined number may be set as appropriate according to the interval between the rollers 2.
That is, a large number of rollers 2 are selected every predetermined number of intervals each time the rollers 2 make a round, and each time the rollers 2 make a round, the first roller 2 to which lubricating oil is injected is selected by shifting one by one. Therefore, the lubricating oil can be injected into all the rollers 2 while the roller 2 makes a plurality of turns. For this reason, even when the distance between the roller 2 and the roller 2 is narrow, it becomes possible to cope with it, and the versatility of the apparatus is improved.
In addition, a pause period for each cycle is set in the pause period setting means 76. An appropriate amount of lubricating oil can be supplied by setting the rest period.
[0033]
Then, idle driving is performed. At this time, the detecting means 72 detects the rollers 2 reaching the lubrication area, and the counting means 73 detects the total number of rollers 2. Then, the number-of-turns calculating means 79 calculates the number of turns in one cycle in which the injection of the lubricating oil into all the rollers 2 is completed from the total number of rollers 2 counted by the counting means 73 and the predetermined number set in the predetermined number setting means 71. To do. This number of laps is stored in one cycle lap number storage means 75. Since the number of laps in one cycle is automatically calculated, it is not necessary for each person to calculate and set the number of laps, and the operability is improved accordingly.
[0034]
Next, the case where the lubrication apparatus S for moving body circulation devices according to this embodiment is operated will be described with reference to the flowcharts shown in FIGS. When the power is turned on (1-1) and the pulley counter (counter means) is started (1-2), the setting is initialized (1-3). In this initialization, the slide cylinder of the traveling body drive mechanism 23 is returned to the origin, the capturing body 26 is opened, the injection nozzle body 30 is opened, the grease pump 51a is operated, and the grease discharge valve 52 is operated. Weighing is performed. In addition, the operation mode is determined.
[0035]
And the detection means 72 detects one specific roller 2, and performs origin confirmation (1-4). When the origin check is not performed (1-4N), an abnormality is output (1-5), and an abnormality is displayed by a lamp or an alarm device (1-6). When the origin is confirmed (1-4Y), the pulley counter (counting means 73) is counted (1-7). Based on the count value of the counting means 73, the execution means 74 is caused to function. That is, it is determined whether or not the execution means 74 is the roller 2 to be injected (1-8), and if it is not the roller 2 to be injected (1-8N), it is determined whether or not the count value is normal (1 -9) If not normal (1-9N), an abnormal output is output (1-10), and an abnormality is displayed by a lamp or alarm (1-11). When the count value is normal, it waits for reading of the next counter value (1-9Y). For example, in the case of skipping one, nothing is performed when the roller 2 to be skipped is detected.
[0036]
On the other hand, when the execution means 74 determines that the roller 2 is to be injected (1-8Y), the slide cylinder of the traveling body drive mechanism 23 is unlocked, and the traveling body 22 is made slidable (1 -12).
Further, as shown in FIG. 2, the capturing body driving mechanism 27 of the capturing mechanism 25 is operated, and the capturing body 26 engages and captures the roller 2 that has been moved to the capturing position Ha and moved to the lubrication area. (1-13).
Then, the control unit 70 detects whether or not the capturing body 26 is engaged with the roller 2 (1-14), and when the engagement of the capturing body 26 is not detected even when a predetermined time comes (1). -14N, 1-15Y), output an abnormality (1-16), display an abnormality with a lamp or alarm device (1-17), and return to the origin (1-18). When it is detected that the capturing body 26 is engaged with the roller 2 (1-14Y), the electromagnetic switching valve 57 is opened to prepare for discharge (1-19).
[0037]
In this state, as shown in FIG. 7, since the roller 2 is captured by the capturing body 26, the traveling body 22 is moved together with the roller 2 and the slide cylinder of the traveling body drive mechanism 23 moves. 70 detects the presence or absence of movement of the slide cylinder of the traveling body drive mechanism 23 (1-20). When there is no movement for a predetermined time (1-20N, 1-21Y), an abnormal output is output ( 1-22), an abnormality is displayed with a lamp or an alarm (1-23), and the origin is returned (1-24). When it is detected that the slide cylinder of the traveling body drive mechanism 23 has moved (1-20Y), the process proceeds to the next control.
[0038]
As shown in FIGS. 3 and 5, first, the injection nozzle body driving mechanism 45 is operated, and the injection nozzle body 30 is supported by the traveling body 22 and advanced to the injection position Ra (2-1).
In this case, as shown in FIG. 5, the injection nozzle body 30 that reaches the injection position Ra has the tip engaging portion 32 engaged with the nipple 6, but there are axial deviations and inclinations of the roller 2 and the nipple 6. The body 31 of the nozzle body 33 is urged by the body urging means 35 so that the center axis of the body 31 coincides with the center axis of the outer cylinder 34. 32, since the flange 37 is biased toward the nipple 6 by the tip engaging portion biasing means 38, each biasing body 40 expands and contracts when pressed against the nipple 6 so that the tip engaging portion. The direction of 32 is corrected according to the direction of the nipple 6, or the direction of the nipple 6 is corrected to match the direction of the tip engaging portion 32. The tilt was forcibly corrected and engaged with bending. Situation can be prevented. In particular, the body urging means 35 is configured by attaching the urging bodies 40 to the outer cylinder 34 at four equal angles (90 °) on the proximal end side and the distal end side, respectively. 38 is configured by attaching four of the urging bodies 40 to the front end side of the outer cylinder 34 in an equiangular (90 °) relationship, so that the urging bodies 40 are arranged symmetrically, so that the nozzle An equal urging force is generated on the main body 33, and the axial deviation and inclination of the roller 2 and the nipple 6 are surely corrected.
[0039]
At this time, the control unit 70 detects whether or not the injection nozzle body 30 has advanced to the injection position Ra (2-2). If advancement is not detected even after a predetermined time has elapsed (2-2N, 2-3Y), an error is output (2-4), and an error is displayed by a lamp or alarm (2-5). Return (2-6). When it is detected that the injection nozzle body 30 has advanced to the injection position Ra (2-2Y), the actuator of the lubricating oil supply unit 50 is driven to discharge the measured grease, and the grease passes through the nipple 6 to the roller 2. Injected (2-7).
In this case, the axial displacement and inclination of the roller 2 and the nipple 6 are surely corrected and the situation where the nozzle body 33 is engaged with the nipple 6 while being bent is prevented. The situation where the leakage of the lubricating oil occurs is prevented.
[0040]
The control unit 70 detects whether or not the discharge has been completed (2-8). If the discharge is not detected after a predetermined time (2-8N, 2-9Y), an abnormal output is output. (2-10), an abnormality is displayed by a lamp or an alarm (2-11).
When it is detected that the discharge is completed (2-8Y), the electromagnetic switching valve 57 is closed (2-12), and the injection nozzle body drive mechanism 45 is operated as shown in FIG. 30 is supported by the traveling body 22 and retracted to the separation position Rb (2-13). In this case, the control unit 70 detects whether or not the injection nozzle body 30 has moved back to the separation position Rb (2-14). , 2-15Y), outputs an abnormality (2-16), displays an abnormality with a lamp or alarm device (2-17), and returns to the origin (2-18).
[0041]
When it is detected that the injection nozzle body 30 has moved back to the separation position Rb (2-14Y), the capture body drive mechanism 27 of the capture mechanism 25 is actuated as shown in FIG. It is moved to the position Hb (2-19). In this case, the control unit 70 detects whether or not the capturing body 26 has been moved to the capturing release position Hb (2-20). −20N, 2-21Y), output an abnormality (2-22), display an abnormality with a lamp or an alarm (2-23), and return to the origin (2-24).
[0042]
When it is detected that the capture body 26 has been moved to the capture release position Hb (2-20Y), the slide cylinder of the travel body drive mechanism 23 is driven, and the travel body 22 is returned to the origin position (2- 26). In this case, the control unit 70 detects whether or not the traveling body 22 has returned to the origin position (2-27), and when the backward movement is not detected even after a predetermined time has elapsed (2-27N, 2 -28Y), output an abnormality (2-29), display an abnormality with a lamp or an alarm (2-30), and return to the origin (2-31).
When it is detected that the traveling body 22 has returned to the origin position (2-27Y), the grease pump 51a is operated (2-32), and the grease discharge valve 52 is measured (2-33). The grease pump 51a is stopped (2-34) to prepare for the next.
[0043]
In this case, if the injection nozzle body 30 does not move back to the separation position Rb or the capturing body 26 is not moved to the capturing release position Hb, an abnormality is detected, but as shown in FIG. In the unlikely event, the trapezoidal plate of the forced moving mechanism 60 may be moved even if the injection nozzle body 30 is moved at the injection position Ra or the capture body 26 is located at the capture position Ha. However, since the trapping body 26 and the injection nozzle body 30 are forcibly opened by relatively entering between the left and right capture bodies 26 at the capture position Ha and the left and right injection nozzle bodies 30 at the injection position Ra, safety is ensured. (2-25).
[0044]
Then, the control unit 70 determines whether or not the one cycle determination unit 77 has reached the number of laps of one cycle stored in the one cycle lap number storage unit 75 based on the count value of the count unit 73. (3-1) When one cycle is not reached, the execution means 74 selects the predetermined number of intervals based on the count value of the count means 73 and injects lubricating oil, and the specific roller 2 makes one round. When the detecting means 72 detects the specific roller 2 again, the lubricating oil is injected by shifting the roller 2 to which the lubricating oil is first injected by one.
[0045]
When the one-cycle determining unit 77 determines that the number of one-cycle laps stored in the one-cycle lap number storing unit 75 is reached based on the count value of the counting unit 73 (3-1Y), the execution control unit 78 However, the pause period data is read (3-2), and the function of the execution means 74 is stopped during the pause period set in the pause period setting means 76 (3-3, 3-4N).
If the execution control unit 78 determines that the set suspension period of the suspension period setting unit 76 has ended (3-4Y), the same control as described above is performed again (3-4Y).
In this way, grease is injected.
[0046]

【The invention's effect】
As described above, according to the lubricating device for a moving body circulating apparatus of the present invention, a large number of moving bodies are selected every time the moving body makes a round, and lubricating oil is injected into the selected moving body. If the moving body to be selected is changed every time the moving body goes around, the lubricating oil can be injected into all the moving bodies while the moving body goes around a plurality of times. Therefore, even if the distance between the moving body is narrow, it becomes possible to cope with it, and the versatility of the apparatus can be improved.
[0048]
According to the lubricating device for a moving body circulating apparatus of the present invention, a large number of moving bodies are selected every predetermined number of intervals each time the moving body makes a round, and lubricating oil is first injected every time the moving body makes a round. Since the moving body to be moved is selected by one and the selected moving body is injected with the lubricating oil, the lubricating oil can be injected into all the moving bodies while the moving body makes a plurality of turns. Therefore, even if the distance between the moving body is narrow, it becomes possible to cope with it, and the versatility of the apparatus is improved.
[0049]
In addition, the control unit includes detection means for detecting a moving body that reaches the lubrication area, and when the detection means detects one specific moving body, the number of moving bodies that the detection means detects based on the specific moving body. The lubricating oil is injected by selecting every predetermined number of intervals based on the count value, and when the specific moving body makes a round and the detecting means detects the specific moving body again, the first lubrication is performed. When lubricating oil is injected by shifting the moving body into which oil is to be injected, the moving body is shifted by one by detecting the moving body by the detecting means and counting this, so that the moving body goes around a plurality of times. In the meantime, it becomes possible to reliably inject the lubricating oil to all the moving bodies.
[0050]
Furthermore, when the control unit sets a pause period for each cycle, an appropriate amount of lubricating oil can be supplied.
Furthermore, in the control unit, the number of laps is calculated by calculating the number of laps for one cycle in which the lubricating oil is injected into all the moving bodies from the total number of moving bodies counted by the counting means and the predetermined number set in the predetermined number setting means. When the means is provided, the number of laps per cycle is automatically calculated, so that it is not necessary for each person to calculate and set the number of laps, and the operability can be improved accordingly.
