Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a stick magazine supply unit that is replaced when a stick magazine containing a plurality of semiconductor devices or the like becomes empty.

(Prior Art) Generally, in order to supply semiconductor devices such as integrated circuits to circuit boards, a cylindrical stick magazine containing a large number of these components is used. For example, JP-A-57-1839
No. 9 describes an invention using this. In other words, a stick magazine (cassette) containing parts,
The stick magazine is housed in multiple stages in a magazine holder (cassette holder) with the supply port at its tip tilted downward, and a component detection sensor is installed in the path of the parts sent out from the bottom stick magazine. When it detects that the parts are exposed, it determines that the bottom stick magazine is empty, holds the second stick magazine from the bottom, drops the bottom stick magazine downwards, and then inserts the second stick magazine from the bottom again. The third stick magazine is released and placed in the lowest position to continue supplying parts.

The lowermost stick magazine mentioned above has its tip supported by a removable movable support (protrusion), and its rear end supported by a fixed support (cassette holder bottom plate). Therefore, the leading end first descends under its own weight, then the rear end detaches from the fixed support, and the whole unit falls downward.0 The above-mentioned unit can be assembled automatically because a large number of parts can be stocked. This is an extremely useful unit for equipment. However, with this unit, an accident may occur where the bottom stick magazine suddenly does not fall as planned. The main causes of this are considered to be errors in the length dimensions of the stick magazine and the falling effect due to its own weight alone. In order to avoid this, it is necessary to provide sufficient space for the height of the fall, but as the compactness causes wet dreams and there is not enough space, unexpected accidents are inevitable.

(Problems to be Solved by the Invention) As mentioned above, the conventional stick magazine supply unit has the inconvenience that an unexpected accident is difficult to avoid because a sufficient falling space cannot be obtained. was created in order to eliminate the above-mentioned disadvantages, and the purpose is to provide a stick magazine supply unit that, despite its compact configuration, can reliably drop the bottom stick magazine and prevent unexpected accidents. shall be.

[Structure of the invention]

(Means and actions for solving problems).

The present invention provides a magazine holder in which hollow rod-shaped stick magazines that house parts inside and feed out the parts from the tip are stacked in multiple stages with the tips facing downward; a component detection sensor that detects the presence or absence of the above-mentioned components; a movable stopper that holds the second stick magazine from the bottom in a detachable manner; and a movable support that detachably supports the tip of the bottom stick magazine. and a rear end support means having a fixed support for supporting the rear end of the stick magazine at the lowest stage, and the movable stopper is operated from the bottom by the movable stopper in response to a signal from the component detection sensor. In the stick magazine supply unit, the movable support body is detached from the tip end after holding the stick magazine of the second stick magazine, and the stick magazine at the lowest stage is dropped from the magazine holder, wherein the rear end support means fixedly supports the rear end. This is a stick magazine supply unit characterized by comprising a detachment actuator for forcibly detaching the stick magazine from the body.

In other words, as the tip falls due to its own weight, the rear end on the fixed support is forcibly removed from the fixed support, so even if the tip does not fall from a sufficient height, it can be reliably removed. Since it leaves, it will definitely fall even though it is Combat 1.
