Description

Detailed Description of the Invention (1) Technical Field of the Invention The present invention relates to a component that automatically receives and discards parts that have been separated from a base material after machining using an NC (numerically controlled) lathe or the like. The present invention relates to an automatic parts receiving mechanism, and particularly to an automatic parts receiving mechanism that receives only parts into a storage box, separating them from chips and cutting oil from mechanical processing.

(2) Prior art and problems The conventional automatic parts receiving mechanism of this building, as shown in Fig. 1, consists of a holding part 2 that holds the processed base material 1,
a cutting blade part 4 for separating the processed part 3 from the
a saucer 5 for receiving the separated part 3; and a receiving tray 5 for receiving the separated part 3;
To separate the parts 3 and receive them into the storage box 6 using such a mechanism, "First, when the machining of one part 3 is completed, the cutting tool part 4
The parting tool 7 descends in the direction of the arrow and begins cutting to separate the component 3 from the workpiece base material 1. At the same time, the tray 5 moves upward from a position below the component 3 in the direction of arrow B, and waits below the component 3. Here, when the part 3 is separated from the workpiece base material 1 by the parting tool T, the part 3 falls onto the receiving tray 5. Next, this tray 5 is used to place the above-mentioned parts 3 into the storage box 6.
Rotate as shown by arrow C and descend. During this process, the component 3 is released and falls into the storage box 6. This operation is repeated to sequentially store the parts 3 into the storage box 6.

However, in this case, the receiving tray 5 and the storage box 6 are located directly below the cutting tool part 4, so they receive almost all of the chips and cutting oil during the machining process of the part 3 and the cutting process. As a result, the chips and cutting oil were mixed together with the separated parts 3 in the storage box 6. Therefore, in the subsequent process, only the parts 3 that have been processed must be extracted, which increases the number of man-hours.

Further, the receiving tray 5 that receives the separated parts 3 rotates downward as shown by the arrow C and releases all the parts 3 into the storage box 6, so that the fallen parts 3 have already been placed in the storage box 6. It often collides with the parts 3 and chips inside, and the parts 3 that have been processed are sometimes damaged. Therefore, product defects occur and the yield rate decreases. Further, since the tray 5 rotates downward to throw out the parts 3 and drop them into the storage box 6, depending on the angle at which the parts 3 are thrown out, the parts 3 do not fall into the storage box 6. Something happened. Therefore, it was necessary to check the number of parts at the final stage, which took 91 hours and increased the number of man-hours.

A wide rail 16.16 extends from the side surface of the base 14 in the axial direction of the holding part 10.
A component transport section 12 is slidably straddled over 6. This component transport section 12 transports the component 3 cut off by the cutting blade section 11 to a storage box 13, which will be described later, and includes a slider 17, a transfer tube 1B, and a finger chuck 1.
9 and Karagaru. That is, the slider 17 is mounted on the rails 16 and 16 and can be slid in the E direction by an appropriate power source, and on the extension of the axis of the workpiece 1 at the top of the slider IT. As shown in FIG. 3, a transfer pipe 1B having a circular diameter through which the component 3 can pass is provided through the transfer pipe 1B, and a finger chuck 19 is screwed into the tip entrance of the transfer pipe 1B on the workpiece 1 side. installed as possible. The finger chuck 19 moves in the direction of the arrow when separating the part 3 from the processing base material 1 with the cutting blade part 11, wraps the part 3, and transfers it to the transfer pipe 18 side. A plurality of slots 20, for example three slots 20, are bored around the circumference. This pickpocket 2
0 serves to spread and envelop the part 3 when the apparent diameter of the part increases due to chips attached to the circumference of the part 3, or to blow off the chips. However, if the inner diameter of the finger chuck 19 is appropriately selected, the slot 20 does not necessarily fray, and a single vibrator may be used.

A storage box 13 for parts 3 is provided behind the parts transport section 12. This storage box 13 receives the parts 3 that have been cut and separated from the processed base material 1 and passed through the finger chuck 19 and the transfer station from the rear end outlet 21, and is formed in an appropriate container shape. , and the transfer pipe 1
At the position where 8 is most advanced in the direction of the arrow, the rear end exit 21
is installed directly below. Therefore, as shown in FIG. 4, the parts 3as, 3b, . End exit 2

It is desirable that the height is high enough to touch the rear end outlet 21 of the. In this way, the falling distance of the component 3 from the rear end exit 21 can be reduced. Further, inside the storage box 13, a net 22 for removing oil such as cutting oil adhering to the parts 3 is installed diagonally and inclined.

In this way, the parts 3 coming out of the rear end outlet 21 of the transfer pipe 18 are inserted into the upper slope of the net 22, and are then positioned downward while rolling on the upper surface of the net 22. During this time, cutting oil and the like adhering to the surface of the part 30 can be shaken off.

Next, the operation of the automatic parts receiving system constructed as described above will be explained with reference to the flowcharts shown in FIGS. 2 and 5. First, for example, an NC lathe to which the present invention is applied is started. In this NC lathe, the material, diameter, etc. of the part 3 to be machined are specified. Next, depending on the diameter of the component 3, a finger chuck 19 of an appropriate size is selected from several types of finger chucks 19 and attached to the tip entrance of the transfer tube 18 of the component transfer section 12. In this state, a program for machining the paper tape to be punched in advance is input. Then, the rod-shaped workpiece 1 is let out by a predetermined length from the holding part 10 shown in FIG. The processing process then proceeds. Next, when this machining is completed, a parting tool for cutting off the component 3 is selected and attached to the cutting blade part 11 in response to the signal. When the cutting tool 14 is cut in this way, the component conveying section 12 moves forward in the direction of the arrow in response to the signal, and its finger chuck 19 wraps the component at the tip of the workpiece 1.

In this state, the parting tool (15) descends in the direction of arrow A and cuts part 3 from a predetermined location! J Mausoleum. All of the chips, oil, etc., fall downward due to gravity. When the separation of the parts 3 is completed in this manner, the parting tool (15) is raised again. Then, the component transport section 12 retreats in the direction of arrow E while keeping the component wrapped in the finger chuck 19. Here, it is checked whether the specified number of machining parts 3 have been completed, and if there is still no machining, the process moves to the lNO'' side in Figure 5 and is fed back before inputting the program, and this cycle is repeated from now on. Return 0 At this time, in the finger chuck 19, as shown in FIG. 4, 1y number of parts 3a, 3b,
. Each time, one component 3 is dropped into the storage box 13P'j from the rear end outlet 21 of the transfer pipe 18. When the specified number of parts 3 have been processed in this manner, the process advances to the YES1' side in FIG. If only you had checked if there was a processing specification for the next part! l
Proceeds to the Y g 3 II side and is fed back before specifying the machined part. If not, the process proceeds to lN0I l1g and all machining of the parts is completed.

(6) Effects of the Invention As explained above, the present invention provides a finger chuck 19.
Since the part 3 separated from the workpiece base material 1 can be taken out horizontally in the axial direction of the workpiece workpiece 1 using the transfer pipe 18, chips during the machining process and cutting/separation process of the workpiece 3 can be removed. Storage box 1 stores only parts 3, completely separated from oil and cutting oil.
You can receive it within 3 days. Therefore, unlike in the past, there is no need to extract only part 3 in the post-process,
It is possible to reduce the number of work hours.

In addition, the storage box 13 for the parts 3 is located at the rear end outlet 21 of the transfer pipe 18.
Since it is provided below, all parts 3 are securely placed in the storage box 13, and there is almost no need to check the number of parts at the final stage, which reduces work time and man-hours. can be reduced. Furthermore, by moving the storage box 13 closer to the rear end outlet 21 of the transfer pipe 18,
