JPS61229714A - Jam detecting device in part feeder - Google Patents

Abstract

PURPOSE:To quickly cope with a part jam and to smooth automatic mounting by disposing a part detection sensor on the inlet and outlet of a straight advancing feeder, and displaying the existence/absence of a jammed part in a display circuit. CONSTITUTION:When a part is transferred by a lift 7 of a straight advancing feeder 6, the part is detected by sensors 11, 12 at the inlet and outlet, respectively. In this case, when the part is smoothly transferred, the part is detected by the sensors 11, 12 within the set time of a timer, and 'no jam' is displayed on a display device not shown. When the outlet sensor 11 does not detect a part within the set time, the display is put out as a part jam, and an alarm is given. In this arrangement, a part jam can be quickly coped with, and automatic mounting is smoothed.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device for detecting clogging when a component transferred by a component supply device becomes clogged.

<Prior art> For example, when an electronic component 4 with a pair of lead terminals 2 and 3 pulled out from a head 1 is automatically mounted on a circuit board as shown in FIG. Components 4 must be supplied to the board in a constant alignment. In order to supply components 4 in such an aligned manner, as shown in FIGS. lift 7
A component supply device is used that receives the component 4 at a location and transfers the component 4 while keeping the posture constant.

The parts 4 are arranged in sequence with the head 1 placed on the lift 7 and both lead terminals 2 and 3 fitted onto the lift 7, as shown in Fig. 5 (from the inlet side to the outlet side of the lift 7). will be transferred.

<Problems to be Solved by the Invention> By the way, when the parts 4 are transferred by the linear feeder 6, the lift 7 may be
A problem arises in that the components 4 are jammed at the top, making it impossible to supply the components to the circuit board, which impedes automatic mounting.

This invention was made to solve the above-mentioned problems, and when a component is clogged on a straight feeder, it can be detected and displayed immediately, and the component can be cleared. It is an object of the present invention to provide a clogging detection device for a component supply device as described above.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention includes a detection sensor for the portion transferred by the linear feeder at each position on the inlet side and the outlet side of the linear feeder. A display circuit connected to the rain detection sensor is arranged to display whether or not there is a blockage of parts on the linear feeder.

Function> The parts sent out from the pole feeder are transferred to the linear feeder, and the parts are transferred while being maintained in their posture by the linear feeder. At this time, the parts are detected by sensors at two places on the inlet side and the outlet side of the linear feeder, and when both sensors detect the part, a no-clog indication is displayed. When a component is not detected, it means that a component is clogged, and the component jam is displayed.

<Embodiments> Examples of the present invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings.

As shown in FIG. 1, the parts supply device is formed by a combination of a pole feeder 5 and a linear feeder 6, and parts 4 are fed by a lift 7 of the linear feeder 6 to positions on the inlet side and outlet side of the linear feeder 6. Detection sensors 11 and 12 are arranged respectively. The sensors 11 and 12 are non-contact sensors such as transmission phototubes and reflection photosensors,
For example, it is arranged to detect the head 1 of the component 4.

As shown in FIG. 2, the display circuit that displays the blockage of the component 4 on the linear feeder 6 based on the output signals of the two sensors 11 and 12 connects the inlet sensor 12 to the output terminal of the component detection signal of the outlet sensor 11. Connect and exit sensor 1
A first timer 13 , a second timer 14 , and an alarm 15 are sequentially connected to the output terminal of the component non-detection signal of 1, and the detection signal of the second timer 14 is fed back to the exit side sensor 11 .

Similarly, a first timer 16 is also provided for the entrance side sensor 12.
A second timer 17 and an alarm 18 are connected, and the detection signal of the second timer 11 is fed back to the entrance side sensor 12, and a no-clog indicator 19 is connected to the output terminal of the parts detection signal of the entrance side sensor 12. has been done.

When the parts 4 are smoothly transferred by the lift 7 of the linear feeder 6 and no clogging occurs, the parts always pass through the sensors 11 and 12 within the time set by the timer on each of the inlet and outlet sides. Therefore, since both sensors 11 and 12 detect the component 4 and issue a component detection signal, the display 19 will indicate the no-clog state.

Further, if the exit side sensor 11 does not detect a component within a set time, the display 19 goes out and the alarm 18 is activated to notify that the component 4 has become clogged on the lift 7 of the straight feeder 6.

Next, if the sensor 12 on the inlet side does not detect a component within a set time, the alarm 15 will be activated to notify that a component has become clogged within the pole feeder 5.

<Effects> As described above, according to the present invention, component detection sensors are arranged at the inlet and outlet sides of the linear feeder, and display circuits connected to both sensors detect the presence or absence of components at the inlet and outlet sides. Since the display is now displayed, it is possible to reliably detect if a component becomes clogged in the pole feeder or on the linear feeder, allowing prompt response to the occurrence of the clog, and ensuring that the automatic component mounting process is not disrupted. I can do it.
