Any shape can be used as long as it can be conveyed by rotation of the drum, but the following description will be given mainly of a narrow plate-shaped work, for example, a material bar, to which the present invention is applied.

[0003]

2. Description of the Related Art Conventionally, as a process for manufacturing chips (capacitors, resistors, and other small electronic components), a rectangular plate-like material plate 14 in which vertical and horizontal lines are provided in the shape of material bars and individual chips in advance. Is divided in a primary dividing step to obtain a material bar 1 (eg, 50.0 mm long, 2.0 m wide)
m, a narrow plate-like body having a height of 0.6 mm).
Is divided in a secondary dividing step 13 to provide a chip t. (See Fig. 5)

[0004] During the step of dividing the material bar into chips, the conveyer 11 passes through a firing furnace 10.
In order to send the material bars 1 conveyed in a plurality of rows side by side to the secondary dividing step to divide them into individual chips t, there is a process in which the material bars 1 must be arranged and conveyed in one row. is there.

However, as shown in FIGS. 6 and 7, the conventional single-row aligning / conveying means comprises a raw material bar 1 which has been conveyed in a plurality of rows (eg, three rows) side by side on a conveyor 11 through a baking furnace 10. Directly into the vibrating ball feeder 15 from the terminal of the conveyor 11 or by hand after the cargo is once collected, and is arranged in a line by the ball feeder 15 and conveyed. The front and back of the bar 1 are aligned (leaving the front (or back) facing upward by the discrimination of the front and back discrimination sensor, and the back (or front) facing upward is returned to the ball) and transported to the secondary dividing step 13 It is intended to be supplied.

[0006]

However, the above prior art has the following problems. Because the material bar is in the shape of a narrow plate,
The material bars put into the ball feeder in a random state are entangled with each other and cannot be easily unraveled, so that the flow until alignment is poor, the efficiency of single-row alignment and transport is extremely poor, and the speed of single-row alignment and transport is slow (eg, , About 60 per minute).

[0007] Since the material bar is elongated and the material itself is hard and brittle (made of ceramic), and the shape of the chip is creased, the collision work due to the work of putting into the ball and the vibration of the entangled object in the ball In many cases, breakage due to conveyance or the like occurs frequently, and those that have been broken and shortened cannot be subjected to the secondary division process, so they must be discarded as defective products, and the processing yield is extremely poor.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a material bar which has been conveyed through a firing furnace without being damaged by handling, vibration, impact, and the like during operation, and furthermore, has a high height which is several times that of the prior art. Efficiency high speed (Example, 120-180 per minute)
The present invention solves the above-mentioned conventional problems by providing an apparatus capable of carrying out one-row alignment in the book.

[0009]

That is, the present invention comprises a drum in which grooves or recesses are formed at equal intervals on the inner peripheral surface of a cylindrical body, and a conveyor inserted and installed in the upper part of the drum.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in the case where a workpiece is mainly a material bar for chips. (FIGS. 1 to 4) A drum 3 having a groove 2 or a recess formed at an equal interval for fitting a narrow plate-shaped work 1 such as a material bar 1 of a tip t on an inner peripheral surface of a cylindrical body is driven to rotate. The work 1 fitted with the suction port 4 in each groove 2 or the concave portion is suction-held by suction force, and the work receiving plate 5 is provided near the rear opening of the drum 3. Conveyor for alignment and conveyance 6
Is a single-row aligning / conveying device for a work, which is provided with the tip of the work inserted into the upper part in the drum 3.

As means for sucking and holding the work 1 fitted in the groove 2 or the concave portion, the intake port 4 is opened in each groove 2 or the concave portion as described above, and the setting along the outer circumference of the upper part of the drum 3 is performed. A communication intake groove 7 is provided between the arc angles so as to constantly take in air, and air is taken in from the intake port 4 while the intake port 4 of each groove 2 or the concave portion of the rotating drum 3 passes through the communication intake groove 7. Thus, the work 1 is sucked and held in the groove 2 or the concave portion. When the work 1 is removed from the communication suction groove 7, the suction of the suction port 4 is stopped, and the work 1 is prepared to drop by its own weight.

Further, a fume nozzle 8 is provided just above the groove 2 or the recessed intake port 4 located just above the conveyor 6, and the fumes of the fume nozzle 8 are passed through the intake port 4 to allow the workpiece 1 to pass through.
The work 1 is provided so as to drop one by one onto the conveyor 6 with a fumarolic force exceeding the suction force.

The work 1 put into the drum 3 is
The front opening of the drum 3 is inclined higher and the rear opening thereof is lowered to make it easier to fit into the groove 2 or the recessed portion by the rotation of the drum 3. Prepare.

When it is necessary to transport the work 1, for example, the material bar 1 in one row while aligning the front and back, a sensor 9 for judging the front and back of the work 1 is provided close to the upper part of the drum 3. An inspection light beam is projected onto the work 1 through a hole (not shown) formed in each groove 2 or concave portion of the drum 3 or a gap between the rear end of the drum 3 and the work receiving plate 5 to determine the front and back of the work 1. After the front (or rear) upward work 1 is dropped from the groove 2 or the concave portion onto the conveyor 6 and passes over the conveyor 6 while the rear (or front) upward work 1 is held in the groove 2 or the concave portion. It is prepared to fall back into the new work 1 in the lower part of the drum 3 due to its own weight falling due to the stop of the intake of the intake port 4.

When the apparatus of the present invention is a dedicated apparatus for the raw material bar 1 of the chip t, the conveyor 11 which conveys the raw material bar 1 in a plurality of rows (in the illustrated example, three rows) through the firing furnace 10 is provided. A conveyor 12 is provided at right angles, and the material bar 1 is received by the conveyor 12 and transported while being aligned in the longitudinal direction. The end of the conveyor 12 is opposed to the front opening of the drum 3 and the material bar 1 is transported. Is supplied to the drum 3 as it is.

The conveyor 12 is divided into a low-speed conveyor at the front stage and a high-speed conveyor at the rear stage, and a large number of material bars 1 conveyed together by the front conveyor are conveyed to a small number of high-speed conveyors at the rear high-speed conveyor. In other words, the drum 3 is charged into the drum 3 in a state of being aligned in the longitudinal direction.

[0017]

The means for loading the work 1 such as the material bar 1 into the drum 3 is optional. For example, the material bar 1 which has been conveyed in a plurality of rows side by side on a conveyor 11 through a baking furnace 10 can be used.
Is dropped and transferred onto a conveyor in front of a conveyor 12 provided orthogonal to the end of the conveyor 11 and transported with the longitudinal direction of the material bar 1 aligned with the transport direction of the conveyor 12,
A small number of drums are put into the drum 3 by a high-speed conveyor at the subsequent stage.

The material bar 1 put in the lower part of the drum 3 slides down by its own weight because the drum 3 is inclined, and the work receiving plate 5
In this state, while being aligned in the longitudinal direction by the rotation of the drum 3, the drum 3 is fitted into each groove 2 or the concave portion, and is conveyed to the upper portion while being rotated. It is sucked and held by force and transported further upward.

When the groove 2 or the concave portion holding the material bar 1 by suction reaches the position immediately above the conveyor 6, the front / back discrimination sensor 9 discriminates the front and back of the material bar 1 and the front (or back) of the material bar 1 facing upward. In this case, the fumarolic nozzle 8 gushes to the intake port 4 and the material bar 1 falls on the conveyor 6 with the gusher force,

In the case of the back (or front) upward material bar 1, it passes over the conveyor 6 while being sucked and held by the intake port 4 as it is, and when the intake port 4 comes off from the communication intake groove 7, the Since there is no air intake, the material falls back into the new material bar 1 in the lower portion of the drum 3 by its own weight. In addition to the fall due to its own weight, a fall back may be forcibly performed by providing a fumarole nozzle or the like.

As described above, the work 1 is placed on the conveyor 6.
Are dropped one by one, so that the material bars 1 successively dropped on the conveyor 6 are aligned in one row and are subjected to the next step, for example, a secondary dividing step of dividing the material bar 1 into individual chips t. 13 is supplied.

[0022]

[Effect] A work such as a material bar randomly placed in a rotationally driven drum is agitated by rotation of the drum, loosened and entangled in the longitudinal direction, and fitted into the groove or recess one after another. Since the sheet is separated and transferred to the upper part of the drum, one piece can be separated and transferred much more efficiently than the conventional ball feeder.

Since the work fitted into the groove or the recess is carried upward by the rotation of the drum and held by the suction force of the suction port, the work can be carried without falling by its own weight.

The work can be aligned and conveyed in one row by inserting the tip of the conveyor into the upper part of the drum and dropping one work held and conveyed in a groove or a recess on the conveyer.

Since the above-described one-piece separation transfer and one-row alignment transfer of the work can both be performed at a high speed, the transfer can be performed at a remarkably high speed as compared with the conventional transfer by a ball feeder (about 60 pipes per minute). , 120-180 lines per minute).

By providing the front and back discrimination sensor, the work can be aligned and conveyed in one row with the front and back of the work aligned.

By rotating the drum with the drum inclined, the loaded work slides down to the lower part and the lower part of the drum by its own weight, and is efficiently aligned in the longitudinal direction while being stirred. Alternatively, the efficiency of fitting the work into the concave portion is high, so that high-speed separation and transfer of individual works can be performed.
