Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for filling a tubular magazine with electronic components such as transistors or ICs.

[0002]

[Problems to be solved by conventional techniques and devices]

 Generally, this type of filling device has a tube-shaped magazine at the lower end of a shoot that slides and drops electronic components one by one, and the magazine extends substantially in line with the chute, and the upper end of the magazine. By arranging the opening of the chute so that it coincides with the lower end of the chute, electronic components transferred along the chute are dropped from the lower end of the chute into the magazine and filled. There is.

However, the inner diameter of the tubular magazine is set to be close to the outer diameter of the electronic component so that the electronic component does not move largely in the magazine. When the chips were dropped from the lower end of the chute into the magazine, electronic components were caught in the opening at the upper end of the magazine, which often resulted in the problem that the electronic parts could not be filled in the magazine.

An object of the present invention is to provide a filling device that does not cause this problem.

[0005]

[Means for Solving the Problems]

 In order to achieve this technical problem, the present invention proposes a tube-shaped magazine at the lower end of a chute that slides and drops electronic parts one by one, and the opening at the upper end of the magazine matches the lower end of the chute. In the filling device configured as described above, a holding member that operates so as to hold the upper end of the magazine is provided at the upper end of the magazine, while the lower end of the chute is provided with or without electronic parts. A sensor for detecting is provided, and the sensor and the actuating mechanism of the holding member are related to vibrate the holding member when the detection of the presence of an electronic component by the sensor continues for a predetermined time.

[0006]

[Work]

 In this configuration, when the electronic parts that slide down one by one from the chute are smoothly falling and flowing into the magazine, the signal provided by the sensor provided at the lower end of the chute that the electronic parts are present may exceed the predetermined time. Since it does not exist, the holding member that holds the upper end of the magazine does not vibrate.

However, when an electronic component falling from the chute toward the magazine is caught in the opening at the upper end of the magazine, the signal indicating that the electronic component is present in the sensor continues for a predetermined time or longer. In response to this signal, the holding member is vibrated by its operating mechanism, so that the electronic component is not caught in the opening at the upper end of the magazine, so that the electronic component falls into the magazine. To do.

[0008]

[Effect of device]

 Therefore, according to the present invention, it is possible to reliably reduce the occurrence of frequent occurrence of the electronic component being caught in the opening at the upper end of the magazine when the electronic component is filled in the tubular magazine, and the electronic component is placed in the tubular magazine. It has the effect of significantly improving the work efficiency when filling.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 indicates a machine frame that is appropriately inclined by an angle θ (θ = about 60 degrees) with respect to the water surface 2. On the upper surface of the machine frame 1, electronic components 3 are intermittently provided one by one. A chute 4 that slides and falls is provided.

In the lower part of the upper surface of the machine frame 1, a tubular magazine 5 is provided, the magazine extending substantially in line with the chute 4, and an opening 5 a at the upper end of the magazine 5 is provided. It is arranged so as to coincide with the lower end of the chute 4. The tubular magazine 5 is placed on the upper surfaces of a lower receiving rail 6 and an upper receiving member 7 fixed to the upper surface of the machine frame 1, and elastically by a pressing member 8 made of a leaf spring. Pressed.

A holding member 10 is provided on the upper end of the tubular magazine 5 so as to press and hold the upper end of the magazine 5 against the receiving member 7 by an operating mechanism in a cylinder 9. On the other hand, a sensor 11 composed of a light emitting element 11a and a light receiving element 11b is provided at the lower end of the chute 4, and this sensor 11 is an operating mechanism for the holding member 10 via a control circuit 12. However, the cylinder 9 is associated with the cylinder 9 so as to reciprocate the cylinder 9 by a relatively small stroke when the detection of the presence of the electronic component by the sensor 11 continues for a predetermined time.

In this configuration, when the electronic parts 3 sliding down one by one from the chute 4 are smoothly falling and flowing into the magazine 5, a signal indicating the presence of electronic parts in the sensor 11 provided at the lower end of the chute 4 is provided. Does not exceed a predetermined time, the holding member 10 holding the upper end of the magazine 5 does not vibrate. However, when the electronic component 3 falling from the chute 4 into the magazine 5 is caught in the opening 5a at the upper end of the magazine 5, the signal indicating that the electronic component is present in the sensor 11 causes a predetermined time. Continuing, the cylinder 9 with respect to the holding member 10 reciprocates with a relatively small stroke in response to this signal, whereby the holding member 10 is vibrated, and this vibration causes the upper end of the magazine 5 to move. Since the electronic component 3 is prevented from being caught in the opening 5a, the electronic component 3 drops and flows into the magazine 5.

In this way, when one tube-shaped magazine 5 is fully filled with the electronic components 3, the magazine 5 is removed from the lower part of the chute 4, and then the lower part of the chute 4 is removed. The empty tubular magazine 5 indicated by the chain double-dashed line is supplied to the portion as indicated by the arrow A 1, and the above filling operation is repeated.
