In the gear-box 21, constitute airtight space, be filled with lubricating oil in the gear-box 21 by oil sealing 31.Because lower shaft 20, shuttle axle 30 and gear 27,28 relative other parts slide, the purpose of filling lubricating oil is wearing and tearing and the heating in order to prevent slipper.
In the industrial sewing machines 1 that as above constitute, the cooling device of Sewing machines is by gear-box 21, detector 12, detector 15, lubricating oil, temperature sensor (being temperature testing organization) 33, electric fan 34, base portion formations such as (being that pedestal 8 reaches cover 13 down), and control device 7 is the control system of double as cooling device also.For improving the particularly radiating effect of gear-box 21 of industrial sewing machines 1, the cooling device of Sewing machines has following formation.
At first, at gear-box 21 in appearance, form a plurality of blades (fin) 21a, the 21a of the prominent bar that extends about the formation that is parallel to each other ... also fixing installing component 35 on gear-box 21, electric fan 34 is fixed on this installing component 35.At the left of gear-box 21, electric fan 34 is configured in the position near gear-box 21.Electric fan 34 is known motor-driven fan, by fan (not shown) with the motor (not shown) etc. of this fans drive rotation is constituted with a plurality of blades, wherein, this blade pass is crossed rotation can produce left from gear-box 21 towards gear-box 21, promptly be parallel to the flowing of wind of the prominent bar direction of blade 21a, 21a, and electric fan 34 relative motors 6 work alone.
Control device 7 has CPU (not shown) and memory (not shown) etc. basically, simultaneously, become and have the known calculation processing unit that carries out the interface (not shown) of the input and output of signal with detector 12, detector 15, temperature sensor 33, power switch 14, motor 6, electric fan 34.Therefore, control device 7 can be controlled motor 6 and electric fan 34 according to the signal that comes self-detector 12, detector 15, power switch 14.
Below, each control method of utilizing control device 7 is described.
In Fig. 7, the operator opens (ON) operation (S1) to power switch 14, and industrial sewing machines 1 integral body is communicated with power supply.After connecting power supply, control device 7 outputs to electric fan 34 (S4) with actuating signal.Receive electric fan 34 actions of actuating signal,, thereby between blade 21a and 21a, cause forced convertion to gear-box 21 air-supplies.Thus, gear-box 21 is cooled.The operator closes (OFF) operation to power switch 14 after, make the dump of industrial sewing machines 1 integral body, electric fan 34 quit work (S2).At this, before power switch 14 was carried out shutoff operation, electric fan 34 was worked continuously, but in electric fan 34 courses of work, when operator etc. topples over sewing machine body 2, detector 12 breakdown actions output to control device 7 (S3) with this start signal.The control device 7 that receives start signal outputs to electric fan 34 with stop signal, makes electric fan 34 quit work (S2).Then, when the operator erects sewing machine body 2, by detector 12 shutdown signal is outputed to control device 7 (S3), the control device 7 that receives shutdown signal outputs to electric fan 34 with actuating signal and makes electric fan 34 actions (S4).In addition, after sewing machine body 2 is toppled over, electric fan 34 quits work, as the operator in case sewing machine body 2 erected when the shutoff operation that power switch 14 is carried out becomes open operation, control device 7 just outputs to actuating signal electric fan 34, so that electric fan 34 is worked well.
Among Fig. 8, after the operator carried out open operation (S11) to power supply 14, industrial sewing machines 1 integrally were communicated with power supply.Then, the operator just can make motor 6 actions (S12) by pedal etc.The action of motor 6 makes detector 15 carry out breakdown action (S14), and start signal outputs to control device 7.The control device 7 that receives start signal outputs to electric fan 34 (S15) with actuating signal.Receive electric fan 34 actions of actuating signal, to gear-box 21 air-supplies, when the operator quit work (S17) by unclamping motors 6 such as pedal, detector 15 cut out (S18), and shutdown signal is outputed to control device 7.At this, before receiving shutdown signal, control device 7 makes electric fan be subjected to Continuous Drive.Therefore, the control device 7 of reception shutdown signal outputs to electric fan 34 (S19) with stop signal.The electric fan 34 that receives stop signal quits work.In addition, control device 7 receives in electric fan 34 courses of work when coming the start signal of self-detector 12, that is, when sewing machine body 2 is toppled over (S16), electric fan 34 quits work.In addition, the operator tramples or loosens pedal and can make motor 6 action or quit work, but according to program, control device 7 can make motor 6 actions or stop, control device 7 also makes electric fan 34 actions when making motor 6 actions, when motor 6 quit work, electric fan 34 also stopped.
As mentioned above, during motor 6 actions, because the lower shaft 20 in the gear-box 21, shuttle axle 30 and gear 27,28 slide, each parts in the gear-box 21 and gear-box 21 heatings, but control method 2. in, in the process of motor 6 work, promptly at gear-box 21 fb durs, the air-supply of electric fan 34 is cooled gear-box 21.Because electric fan 34 also quits work when motor 6 stops, and therefore, can suppress the power consumption of electric fan 34.
As mentioned above, each parts during motor 6 action in the gear-box 21 and gear-boxes 21 heatings, but in the course of work of the motor 6 of control method in 3., electric fan 34 actions are cooled gear-box 21.In addition, even motor 6 quits work, each parts in gear-box 21 and the gear-box 21 also can maintain the condition of high temperature in some cases, but still work continuously because of electric fan 34, and therefore, each parts in gear-box 21 and the gear-box 21 are cooled.Then, because back electric fan 34 quits work at the appointed time, after each parts in gear-box 21 and the gear-box 21 were sufficiently cooled, electric fan 34 quit work, and therefore, can suppress the power consumption of electric fan 34.
Control method 4.
When industrial sewing machines 1 integral body was connected power supply, control device 7 covered 13 interior temperature under judging according to the signal of the displays temperature of temperature sensor 33 outputs.The slip of lower shaft 20, shuttle axle 30 and gear 27,28 in the gear-box 21 is risen each part temperatures in gear-box 21 and the gear-box 21, the temperature of covering down in 13 also rises, temperature under control device 7 is judged in the cover 13 becomes set point of temperature when above, and actuating signal is outputed to electric fan 34.Receive electric fan 34 actions of actuating signal.Before temperature under control device 7 is judged in the cover 13 becomes below the set point of temperature, electric fan 34 Continuous Drive.Temperature under control device 7 is judged in the cover 13 becomes set point of temperature when following, and stop signal is outputed to electric fan 34.The electric fan 34 that receives stop signal quits work.In addition, the temperature the when temperature when out-of-work electric fan 34 is moved stops with the electric fan 34 in making work can be different, also can be identical.In addition, control device 7 receives when coming the start signal of self-detector 12 in electric fan 34 course of action, and electric fan 34 is quit work.
As mentioned above, during motor 6 actions, can make each parts and gear-box 21 heatings in the gear-box 21, the temperature of covering down in 13 rise, but control method 4. in, be that temperature in gear-box 21 becomes set point of temperature when above, electric fan 34 just moves, so that gear-box 21 is cooled off.In addition, cooling gear-box 21 make play cover 13 interior temperature become set point of temperature when following electric fan 34 just quit work so that gear-box 21 becomes the natural heat dissipation state.Like this, owing to reach when wanting chilling temperature covering temperature in 13 down, electric fan 34 just moves, and when down the temperature in the cover 13 do not reach the temperature that will cool off, electric fan 34 is not worked, therefore, each parts that can suppress in gear-box 21 and the gear-box 21 when suppressing electric fan 34 power consumption are overheated or cold excessively.
Hereinafter will the effect of present embodiment be described.In above embodiment, electric fan 34 not with last axle 16 interlocks, and motor 6 moves independently or stops relatively.Therefore, even motor 6 quits work, just industrial sewing machines 1 quit work, and electric fan 34 also can be worked continuously.Like this, even motor 6 quits work, each parts in gear-box 21 and the gear-box 21 also can be in the situation of keeping high temperature, even also can blow continuously to gear-box 21, thereby can each parts in gear-box 21 and the gear-box 21 be cooled off yet Yin Mada 6 has stopped work electric fan 34 with working on.
In addition, because electric fan 34 is configured in the front-left of gear-box 21, the wind that electric fan 34 produces directly is blown into gear-box 21, the good heat dissipation effect of each parts in gear-box 21 and the gear-box 21.In addition, the air supply direction almost parallel ground of blade 21a, 21a and electric fan 34 extends, so the wind that electric fan 34 blows out can flow between 21a, 21a expeditiously.Therefore, can leave the efficiently heat of gear-box 21.
