New type of use: [New technical field] The present invention relates to a detecting device, and more particularly to a detecting device for a tool for an induction molding machine. [Prior Art] A molding machine is a commonly used industrial machine. Whether it is used for drilling a screw hole or for external machining, it is necessary to drill an aperture in an object or perform a work outside the workpiece. In the automated molding operation, the clamping mechanism of the molding machine must be clamped and replaced into tools with different apertures according to the set line order. However, if the clamping mechanism is not taken up or lowered smoothly, the next time the tool extraction operation is performed, Another tool has an interference collision, which causes the tool to be damaged, and the machining operation must be interrupted, resulting in unnecessary cost loss. To avoid this, the operator must be monitored at any time to monitor whether the tool correctly lifts or lowers the tool according to the setting program. The manpower-based monitoring method is prone to loss, and it is not the most ideal choice for production cost considerations. Therefore, if manual monitoring can be replaced by induction monitoring mode, it is believed to be a better implementation option. [New content] Therefore, the object of the present invention is to provide a detecting device capable of inductively monitoring whether there is still an unextracted tool on the carrier, so as to avoid collision damage caused by repeatedly placing the tool on the loaded tool holder. Therefore, the present invention is suitable for use in a molding machine having a work table for placing a work object, a cutter mechanism for gripping a tool, a tool holder for temporarily holding the tool, and a cutter mechanism for driving the clamp. Moving together on the workbench to enable the tool held by the clamp tool mechanism to work on the work object M294384. The tool detecting device includes a detector, and the detector can sense whether a through hole of one of the tool holders can pass through the light transmission line. The detector can sense whether a tool is placed on the loaded tool holder, thereby preventing the lost tool mechanism of the clamped tool from colliding with the tool on the loaded tool holder, resulting in loss of mechanical damage. [Embodiment] Referring to Fig. 1, a preferred embodiment of the novel tool detecting device 1 is used in conjunction with a molding machine 2 (for convenience of explanation, the embodiment and the illustration are illustrated by the drilling method), the molding is performed. The machine 2 has: a work table 21, a main clamping tool mechanism 22, a sub-clip tool mechanism 23, two mutually spaced load tool holders 24 and 25, a tool holder disk 26 for most tool placement, and a power source (It is a motor, but it is not shown in the figure). Among them, the main clamping tool mechanism and the sub-clamping tool mechanism 23 are driven by a power source to perform a gripping tool operation. The secondary clamp cutter mechanism 23 is disposed adjacent to the primary clamp cutter mechanism 22, and both are driven by the power source to move axially above the table 21. The first load tool holder 24 is identical in structure to a second load tool holder 25. For convenience of explanation, the first load tool holder 24 will be described as an example. The first load tool holder 24 includes a circular shape. The base 24 defines a disk 242 disposed at the top of the base and a receptacle 243 extending longitudinally through the disk 242. ‘The insertion hole 243 is smaller than the maximum outer diameter of the cutter 3 so that the cutter 3 does not completely fall into the insertion hole 243, and the tip end of the cutter 3 protrudes outside the insertion hole 243 and can be gripped by the cutter mechanism 22 or 23. The detecting device 1 includes a detector U, a light source 12 and a sensing circuit 13. The light source 12 is a visible light source (in this case, the light-emitting M294384 diode (LEH) is taken as an example), and is fixed at the lower end of the first and second cutting tool holders 24, 25 at the lower ends of the insertion holes 243, 253. When the cutter 3 is accommodated in the insertion hole 243 of the first carrier holder 24, the light projected by the light source 12 is blocked by the cutter', and the through hole 243 cannot be smoothly penetrated. The detector 11 is a light-receiving diode mounted on the sub-clip cutter mechanism 23, and moves along with the sub-clip cutter mechanism 23.
如圖3所示為一電路示意圖，說明該偵測器11可依據 接收光源12大小而產生程度不同之電流，經由電阻將電流 傳至比較放大器131’最後經由電阻和電晶體組合而成之反 相器132輸出，藉此作為判定該光源12之投射光源是否受 到刀具遮擋。 鑽孔作業時係按照一定程序進行，首先，主夾刀具機 構22連同副夹刀具機構23由工作台21上方移動到刀具座 盤26上方，該副夹刀具機構23下降到刀具座盤％，夹起 其中-個刀具4後上升定位’主、副夹刀具機構以與23 繼而-同位移至載刀具i 24上方，依序位移進行換刀作 業。在加工自動化連續作業的過程中主、副夹刀具機構22、 23需時常於第一、二載刀具座2“ 25上進行換刀作業。 在前述步驟中，若因機具操作因素或程式控制不當刀 具未能正常抓取，造成主、副夹刀具機構22、23未能順利 取走刀具3’導致刀具3被遺留在第一、二載刀具座μ、 25上’等到主、副夾刀具機構m再次返回第一 刀具座24、25上方’夾取下一個刀具之副夾刀具 欲下降而放置刀具在載刀具座24、25之插孔243 時，因感應器1會於先於主7、副夹刀具機構22、23定位於 M294384 第-、二彻具㈣、25上题先_通㈣進卿測， 而先源12之投射光線被刀具3遮擋（如第二圖所 順利透出該第-載刀具座25之插孔243，摘測器n感應不 到光線’便由電路1 3回傳訊雜，八士相丨 ⑽μ 、成型作業暫停並警告操 作人員第一載刀具座24上仍留有刀具3。 、24因機具操 ’造成換刀作 如此一來，可避免主、副夾刀具機構23 作因素或程式控制不當，造成刀具未抓取時 業碰撞的毀壞。As shown in FIG. 3, a circuit diagram is illustrated, which illustrates that the detector 11 can generate different currents according to the size of the receiving light source 12, and the current is transmitted to the comparison amplifier 131' via the resistor, and finally the reverse combination of the resistor and the transistor. The phaser 132 outputs, thereby determining whether the projected light source of the light source 12 is blocked by the tool. The drilling operation is performed according to a certain procedure. First, the main clamping tool mechanism 22 and the secondary clamping tool mechanism 23 are moved from above the table 21 to above the tool holder disk 26, and the secondary clamping tool mechanism 23 is lowered to the tool holder disk %, and the clamp is lowered. After one of the tools 4 is raised and positioned, the main and auxiliary clamp tool mechanisms are moved to the top of the loaded tool i 24 with 23 and then displaced in sequence, and the tool change operation is performed in sequence. During the continuous operation of the machining automation, the main and sub-clamping tool mechanisms 22, 23 are often required to perform the tool change operation on the first and second load tool holders 2" 25. In the foregoing steps, if the tool operation factors or programs are improperly controlled The tool failed to be properly grasped, causing the main and auxiliary clip tool mechanisms 22, 23 to fail to remove the tool 3', causing the tool 3 to be left on the first and second load tool holders μ, 25 'to wait for the main and auxiliary clip tool mechanisms. m again returns to the first tool holder 24, 25. 'The sub-clip tool for gripping the next tool is to be lowered and the tool is placed at the insertion hole 243 of the tool holder 24, 25, since the sensor 1 will precede the main 7, The sub-clip cutter mechanisms 22, 23 are positioned on the M294384 first-, second-two (four), 25-first-first-pass (four) into the Qing test, and the projected light of the first source 12 is blocked by the cutter 3 (as shown in the second figure) The jack 243 of the first-loading tool holder 25, the sensor n does not sense the light', the circuit 1 3 returns the signal, the october phase (10) μ, the molding operation is suspended and the operator is still on the first load tool holder 24 There are tools 3, 24, because the machine tool 'causes the tool change, so Avoid the primary and secondary clamp cutter mechanism 23 as factors or improper control program, resulting in the destruction of the tool did not grab the collision industry.
本實施例透過光源12投射出光線，並根據光線是否受 到刀具播止來判；t載刀具座24、25上是否仍遺留有未被央 取之刀具，右光線未党到遮擋而可被該偵測器丨丨所感應， 代表載刀具座24、25丨未殘留任何刀具，該夾刀具機構 23、24可以無慮地將進行連續換刀作業；但若光線受到遮 擋後，該偵測器11無法取得任何光線感應，便無法輸出電 流，最後透過反相器132輸出訊號，暫停整個夾刀具機構 22、23移動行程，防止夾刀具機構22、23與刀具，或者刀 具間碰撞造成損失。 此外’本實施例所揭示之光源12是裝設在第一、二載 刀具座24、25下端適當位置，並經由貫穿樣插孔243、253 透出而被偵測器11所感應，惟在實際實施態樣下，該光源 U只需為可見光源，而其可與偵測器丨丨的設立位置可彼此 交換，亦即該偵測器11改設於該第一、二載刀具座25下 方適當位置處，至於該光源12則是被固定於該副夾刀具機 構23侧’該偵測器丨丨更可以獨立設置，也就是直接感應 週遭環境中的光線；若環境中的光線能夠經由該第一、二 8 M294384 載刀具座2 4、25之插孔24 3 、2T3透入，使代表該第一、 二載刀具座24、25上並無刀具。另一方面，本實施例係偵 測與該副夾刀具機構23搭配之第一、二載刀具座25上是 否仍有未取用刀具，在同樣概念下，該偵測器i丨與光源12 彼此配合之偵測原理也可以應用於刀具座盤26，避免碰撞 情形發生。In this embodiment, the light is projected by the light source 12, and is judged according to whether the light is blocked by the tool; whether the tool that is not taken by the center is left on the tool holders 24 and 25, and the right light is not blocked by the party. The detector 感应 senses that no tool remains on the load tool holders 24, 25丨, and the cutter tool mechanisms 23, 24 can perform continuous tool change without any concern; however, if the light is blocked, the detector 11 If no light sensing is obtained, the current cannot be outputted. Finally, the signal is output through the inverter 132, and the movement of the entire clamping tool mechanism 22, 23 is suspended to prevent the collision between the clamping tool mechanism 22, 23 and the tool or the tool. In addition, the light source 12 disclosed in the embodiment is installed at the lower end of the first and second load tool holders 24, 25, and is exposed by the detector 11 through the through-holes 243, 253, but In actual implementation, the light source U only needs to be a visible light source, and the set positions of the detectors 丨丨 can be exchanged with each other, that is, the detector 11 is modified to the first and second load tool holders 25 . At the appropriate position below, the light source 12 is fixed to the side of the secondary clip tool mechanism 23. The detector can be independently arranged, that is, directly sensing the light in the surrounding environment; if the light in the environment can pass through The jacks 24 3 and 2T3 of the first and second 8 M294384 carrying tool holders 2 4 and 25 penetrate therein so that there are no tools on the first and second load tool holders 24 and 25. On the other hand, in this embodiment, it is detected whether there is still an unused tool on the first and second load tool holders 25 matched with the sub-clip tool mechanism 23, and in the same concept, the detector i 丨 and the light source 12 The principle of detection that cooperates with each other can also be applied to the tool holder disk 26 to avoid collision situations.
