Abstract
A method of conveying a workpiece on an asynchronous assembly line provided with at least one first work table and one second work table. The inlets and the outlets of the first and the second work tables are provided with workpiece sensors. And then when a workpiece is detected at the outlet of the first work table and no workpiece is detected at the inlet of the second work table, the workpiece at the outlet of the first work table is conveyed to the second work table.
Description
The present invention relates to a kind of method that is used for conveying work pieces on asynchronous assembly line.
The representative type fitting line is classified into synchronized model and asynchronous type.The synchronized model fitting line is a kind of like this fitting line, wherein the transmission of workpiece from a processing to next processing place carried out simultaneously, and asynchronous type fitting line is a kind of like this fitting line, and wherein workpiece is independently to finish by each processing place to the transmission of next processing place.
In traditional asynchronous type fitting line, the workpiece sensing device only is located at the export department office of each machine table.Thereby, when detecting when not having workpiece, be transferred into second machine table at the workpiece of the first machine table exit portion by a workpiece that detects at the workpiece sensing device in the first machine table exit and at the workpiece sensing device of the second machine table exit portion.A kind of method that is used for conveying work pieces on such asynchronous assembly line is in US Patent the 4th, 884, and is open in No. 674.
Fig. 1 provides an asynchronous assembly line of the orthodox method that is used to explain conveying work pieces.Referring to accompanying drawing, in this conventional asynchronous fitting line, workpiece sensing device PH1, PH2 and PH3 provide in each exit portion of machine table 1,2 and 3.Workpiece W in the exit portion of one (N-1) machine table 1 is detected by the first workpiece sensing device PH1.At this moment, when the workpiece (not shown) N machine table 2 exit portion was detected by the second workpiece sensing device PH2, the first motor M1 was not driven and keeps static.Then, when the workpiece N machine table 2 exit portion is transferred into (N+1) individual machine table 3 and does not have workpiece to be detected by the second workpiece sensor device PH2 in the exit portion of N machine table 2 thus, the first motor M1 is driven.Therefore, the workpiece in the exit portion of (N-1) individual machine table 1 is transferred into N machine table 2.In traditional method that is used for conveying work pieces, the workpiece in the processing is only detected in the exit portion of corresponding machine table 1,2 and 3.Thereby, machine table 1,2 and each machine table place of 3 be used to wait for that the time of workpiece becomes relative longer, this is because to be used for the overhours of first machining area on asynchronous assembly line different.
For overcoming the problems referred to above, the object of the present invention is to provide a kind of method that is used for conveying work pieces, with this kind method, the relevant position of each workpiece can be in the intake section and the exit portion check of each machine table of an asynchronous assembly line.
Therefore, for achieving the above object, the invention provides one and be in the method that transmits a workpiece in the asynchronous assembly line that has one first machine table and one second machine table at least, this transfer approach comprises step: intake section and exit portion everywhere in first machine table and second machine table all provide the workpiece sensing device; When detecting workpiece in the first machine table exit portion and when the intake section of this machine table detects no workpiece, transmitting workpiece to the second machine table that is in the first machine table exit portion.
In the foundation method that is used for conveying work pieces on an asynchronous assembly line of the present invention, workpiece checks the corresponding location of workpiece to transmit by intake section and exit portion in a machine table, makes to be used for waiting for that in each machine table the time of workpiece can be reduced a lot.
Preferably, optical sensor or limit switch can be used as the workpiece sensing device.
Above-mentioned purpose of the present invention and advantage describe preferred embodiment in conjunction with the drawings in detail and will become more apparent, wherein:
Fig. 1 is a plan sketch, and an asynchronous assembly line is shown, and is used to explain the orthodox method of conveying work pieces;
Fig. 2 is a plan sketch, and an asynchronous assembly line is shown, and is used to explain the method that is used for conveying work pieces according to the present invention;
Fig. 3 is a diagram of circuit, is used to explain the asynchronous assembly line at Fig. 2, from the method for N machine table of (N-1) individual machine table conveying work pieces to the.
Referring to Fig. 2 and 3, optical sensor PH1, PH2, PH3 and PH4 are provided at each intake section and the exit portion of N-1 machine table 1 and N machine table 2 respectively.Here, detect a workpiece W (step S1) and when the exit portion of the second optical sensor PH2 in N-1 machine table 1 when the optical sensor PH3 of N machine table 2 intake sections detects no workpiece (step S2), the workpiece in the exit of N-1 machine table 1 is transferred into N machine table 2.
After this, the process of conveying work pieces will be described in detail in conjunction with Fig. 3.
When workpiece W was sent to N-1 machine table 1, the first optical sensor PH1 connected.When workpiece W after N-1 machine table 1 is processed, when workpiece W was in the exit portion of N-1 machine table 1, the second optical sensor PH2 connected (step S1).When the intake section N machine table 2 detected the workpiece that does not have in front, the 3rd optical sensor PH3 closed (step S2).When the second optical sensor PH2 connects and the 3rd optical sensor PH3 when closing, the first motor M1 is driven a schedule time (step S3).Correspondingly, the workpiece W that is positioned at N1 machine table exit portion can be transferred into the intake section of N machine table 2.Above-mentioned step S1, S2 and S3 repeat till machining (step S4).Be used for to be sent to the method for the intake section of N+1 machine table 3 at the workpiece of N machine table exit portion, carry out with identical load mode with above-mentioned explanation.
As mentioned above, the method that is used for conveying work pieces on an asynchronous assembly line in foundation the present invention, relevant position at each workpiece of the intake section of each machine table and exit portion is verified, thereby is used for waiting for that in each machine table the time of workpiece can be reduced a lot.
The invention is not restricted to present embodiment and can make amendment and improve by those skilled in the art.For example, limit switch can be used to replace the optical sensor PH1 to PH6 among Fig. 2.
