Abstract

PROBLEM TO BE SOLVED: To double the number of chips of conducting into an arranging passage, and of storing in such a manner than chips, which are dispersed by a jet stream and fall, are subjected to posture control by a magnet so as to arrange in a line, allowing the chips to fall by their own gravity keeping its state, and to glide down into an arranging way from the entrance of the arranging way, with the chips stored. SOLUTION: With the jetting out of gas from a jet 8, chips (t), such as chip type resistor, other small electronic parts, and the like, fallen from a storage chamber 2 into a dispersing chamber 4 are blown up and dispersed due to jet gas, allowing them to fall down on the gliding down bottom surface 4a. Then, if the chips (t) enters into a magnetically affected zone about a magnet 7, the chips (t) slightly respond to magnetic absorbing force, so that their disordered postures in falling down stage are controlled to a regular direction by the magnetic absorbing force, allowing them to be arranged in a line on the gliding down bottom surface 4a. Further, keeping the posture, the chips glide down on the gliding down bottom surface to an entrance 5a of an arranging way 5 by their own gravity, successively glide down into the arranging way 5 from the entrance 5a of the arranging way 5 with the chips stored, then the chips are separated one by one using a one by one separating mechanism 6, and sent to the following step.

2. Description of the Related Art The applicant of the present application has filed as a prerequisite application of the present application in Japanese Patent Application Laid-Open No. 62-280129, "Chip Separation Alignment Device", and No. 63-127600 "Chip Separation Alignment Device with Cartridge Type Chip Case". Dosho 63-22502
No. 5 "Chip Separation and Alignment Device", Actual Development Sho 63-14493
No. 0 "Separation / feeding device for one solid object" or the like is used to drop the chips into the diffusion chamber from the storage chamber of the separation device that stores a large number of chips in a loose state, or to separate a large number of chips. In this state, the chip cassette housed in the state is detachably attached to the separation device part, and the chips in the chip cassette are dropped into the storage chamber of the separation device part, dropped from the storage chamber into the diffusion chamber, and the chips in the diffusion chamber are removed. While being diffused by the jet stream, they are introduced into the alignment path in a single-row alignment, and an appropriate one-to-one separation mechanism provided near the exit of the alignment path sequentially moves from the top chip to 1
We have developed a chip separation and alignment device and related development that decided to separate the chips and send them to the next process.

However, with the chip separating and aligning apparatus A'as it is, even if the chips in the diffusion chamber are blown out by the jet flow of the fumaroles and diffused, most of the dropped chips are congested near the entrance of the alignment path. Therefore, the number of chips that slide down on the glide bottom surface by its own weight and slide down into the aligned road in a single row from the aligned road entrance is about 1 to 2 per fumarole. , They were stored in the line. (See Fig. 4)

However, in recent years, as the next step of the chip separation and alignment apparatus is remarkably speeded up and the efficiency is increased,
It becomes necessary to separate and supply one chip from this device at a high speed in accordance with the next process, and as a result, the number of chips stored in the alignment path may become insufficient, so that each time the fumes are ejected. It has become an urgent and important task to increase the number of chips to be introduced into the alignment path and increase the number of chips stored in the alignment path to cope with the speeding up of separation of one chip.

The present invention effectively solves the above problems. That is, according to the present invention, the chips are dropped into the diffusion chamber from the storage chamber of the separation device unit in which a large number of chips are stored in a loose state, or the chip cassette in which a large number of chips are stored in a separated state is separated into a separation device unit. Detachably provided, the chips in the chip cassette are dropped into the storage chamber of the separation device unit, dropped from the storage chamber into the diffusion chamber, and the chips in the diffusion chamber are diffused by the jet stream into the alignment path. It is introduced into the row alignment, and the appropriate separation mechanism for one chip provided near the exit of the alignment path separates the chips one by one from the foremost chip and feeds them to the next process. In the device,

A chip is placed in the diffusion chamber, which is diffused by the air flow from the fumaroles, and slides down toward the entrance of the alignment passage. The tip of the tip diffusing and descending due to the flow is controlled by a weak magnetic attraction force exerted on the tip by the magnet so that the tip is aligned in a line lying on the bottom surface of the glide surface, and the weight of the tip slides down while maintaining that posture. The present invention has solved the problem by a chip separation and alignment device equipped so as to slide down into the alignment path in a single row and be stored.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, referring to the drawings, an embodiment of the present invention will be described. In this embodiment, the chips t are dropped into the diffusion chamber 4 from the storage chamber 3 of the separation unit 1 in which a large number of chips t are stored in a loose state.
Alternatively, a chip cassette 2 accommodating a large number of chips t in a loose state is detachably provided in the separation device part 1, and the chips t in the chip cassette 2 are dropped into a storage chamber 3 of the separation device part 1 to store the chips t. The alignment path 5 is dropped from the chamber 3 into the diffusion chamber 4 and the chips t in the diffusion chamber 4 are diffused by the jet stream.
It is introduced into the inside in a one-row alignment, and an appropriate one-to-one separation mechanism 6 provided near the exit of the alignment path 5 sequentially inserts 1 from the top tip t.
In the chip separating and aligning device, which was decided to separate and send to the next process,

The tip t in the diffusion chamber 4 diffused by the air flow from the fumaroles 8 slides down toward the entrance 5a of the alignment passage, and at a position close to the entrance 5a of the alignment passage 4a on the bottom surface 4a of the diffusion chamber 4 or below it. The magnet 7 is installed, and the tip t that is diffused and dropped by the jet stream is controlled by a weak magnetic attraction force acting on the tip t by the magnet 7 so that the tip t is arranged in a single line on the downhill bottom surface 4a. A chip separating and aligning device A is provided so that it can slide down by its own weight in that posture and slide down into the aligning path 5 from the aligning path inlet 5a in a single-row alignment to be stored.

The chip is a chip-type resistor or other small electronic component, a small mechanical component or any other small article that weakly reacts to the magnetic force of a magnet and is magnetically attracted.

The magnet 7 is a permanent magnet such as ferrite, and the magnetic attraction force of the magnet 7 is
The tip t, which is diffused by the jet stream and is in a free posture during the fall, is weakly sucked, and the posture of the tip t with respect to the magnet 7 is controlled and aligned in a certain direction, that is, one row is arranged on the glide bottom surface 4a. Although it has a force to align it in the lying posture, there is no force to stop the adsorption of the tip t on the downhill bottom surface 4a. Therefore, the tip t is attracted by the magnet 7 and the self-weight causes the tip t to fall on the downhill bottom surface 4a to the alignment path entrance 5a. It is provided by adjusting the magnetic force of the magnet itself or adjusting the distance between the magnet and the bottom surface of the slide so as to slide down.

In the illustrated embodiment, the tip cassette 2 is detachably provided in the storage chamber 3 portion of the separation device section 1. Although not shown, the storage chamber itself is formed large so as to be a chip cassette type. It may not be done.

[0011]

[Operation] When the fumes are blown from the fumaroles 8, the storage chamber 2 to the diffusion chamber 4
The tip t that has fallen inside is blown up by the jet stream, is blown away, diffuses, and falls onto the slide-down bottom surface 4a. At this time, when the tip t enters the magnetic field of the magnet 7, the tip t weakly reacts to the magnetic attraction force, and the free posture during the fall is controlled in a certain direction by the magnetic attraction to be on the downhill bottom surface 4a. The person is in a posture of lying in one row, and then, while keeping that posture, it slides down on the downhill bottom surface 4a toward the alignment path entrance 5a by its own weight (a force stronger than the attraction force of the magnet 7), and the entrance 5
After being slid down into the alignment path 5 from a and stored, it is separated into one by the one-by-one separation mechanism 6 and sent to the next step.

The action of introducing the chips into the alignment path is repeated for each shot of the fumes, so that the chips t are sent into the alignment path 5 one after another with high efficiency and stored therein.

[0013]

[Effects] The tips that diffuse and fall due to the jet flow are controlled by the magnetic attraction force of the magnet so that they lie in a single line on the bottom surface of the diffusing chamber. Since the slide-down approach is made and the water is stored, there is an excellent effect that the number of chips to be introduced into the alignment path and the number of chips to be stored can be increased to about 1.5 to 2 times the conventional number.

Since it suffices to install a small magnet on the downhill bottom surface near the entrance of the alignment road or on the lower part thereof, there is an advantage that there is almost no influence in manufacturing and cost.

The device of the present invention can be applied to the single-piece separation and alignment of chip resistors and other small electronic parts, small mechanical parts and other small objects that respond to the magnetic attraction of a magnet.
