Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial Field of Application) The present invention is an inspection device for sampling and inspecting the quality of printing on blanks in the can manufacturing process.

(Prior art) Among canned goods, those called 3-piece cans are
Printing is done on a flat can body material called a blank, which is then cut into 12, 16, etc. pieces to create individual can body materials. In order to inspect the quality of the ink adhesion and the presence of color shifts while being transferred from the printing press to the oven, workers traditionally would manually pick up the blanks that are being fed at high speed, hold them in their hands, and carry them to the inspection table. , I was putting this back on the line again. In addition to the safety issues that arise from handling blanks by hand, errors such as misplacing the end of the blank when returning it to the line can also cause problems, such as in easy-oven cans where the ends are in the opposite position. There were also problems with quality control, such as the production of

(Problems to be Solved by the Invention) In this invention, even though the operator selects which blank to inspect, after selection, the blank is automatically brought to a position where the operator can easily inspect it. By automatically returning the blank to the line after the inspection is completed, the objective is to obtain a blank sampling inspection device that does not have the above-mentioned problems.

Structure of the Invention (Means for Solving Problems) The inspection device of the present invention is arranged between a blank printing machine and an oven, and has a first lever for taking out one blank out of the normal transfer path. , a second lever that senses the entry of the blank, tilts the blank perpendicular to the blank transport path to a position where it can be easily inspected by an operator, and returns to its original position in response to an inspection completion signal; Upon sensing the entry of the blank into the second lever, the blank is released and the second
and a third lever that moves to the return position of the lever and returns to the original position when the second lever returns.

(Function) Blanks that leave the printing press and are normally transferred to an oven by a belt conveyor or the like are removed from the conveyor in single piece by actuating a first lever that may be actuated manually. then step onto the second lever. When a suitable detector such as a microswitch senses this, the second lever is rotated with the blank placed thereon, and the blank is tilted so that it can be easily inspected by an operator. At the same time, the third lever on which the inspected blank was placed is switched to the blank and the first lever by the signal from the second lever's detector.
It is taken out by the lever and discharged onto the empty conveyor, and moved to the return position of the second lever.

When the operator issues an end signal using an end-of-inspection button or the like, the second lever places the inspected blank and returns to its original position. The third lever has already moved there as described above, and in response to the return signal from the second lever, the third lever places the inspected blank and returns to its original position, preparing for the next discharge.

(Example) FIG. 1 is a schematic diagram showing the operating sequence of the inspection device of the present invention.

The blank 1 is conveyed from the printing press 2 by a conveyor 3 to an oven. A first lever 4, which can be operated manually or by a push button in accordance with the timing of blank conveyance, is arranged in the middle of the process, and rotates to the dotted line position and immediately returns to flip up only one blank and move the 2 Take it out onto the lever 5. A detector, for example a microswitch 6, provided on the second lever detects that a blank is placed on the second lever.

As seen in FIG. 2, the second lever 5 includes a plurality of support rods 51 and a shaft 52 extending parallel to the conveyor.
It can be rotated around , as shown in Figure 3. 53 is a blank stopper that approaches from the direction of the arrow. As described above, when the detector 6 detects that the blank has entered onto the second lever, the lever 5 rotates to the dotted line position in FIG. 3 and tilts the blank 1 to facilitate inspection by the operator. 54 is a stopper that supports the blank 1 at this time.

As shown in FIG. 2, the third lever 7 consists of a plurality of support rods 71 located between the support rods 51 of the second lever and a rotation shaft 72 extending at right angles to the conveyor, and normally as shown in FIG. The inspected blank is placed in an inclined upward position.

The detection signal from the detector 6 activates the actuating device such as the air cylinder 9, and the stopper 8 is released and the inspected blanks placed thereon are flipped up by the first lever 4 and transferred to the empty conveyor 3. The lever 7 is lowered into the upper position, and then the lever 7 rotates as shown by the arrow in FIG. 4 and stops at the flat position of the second lever 5 before actuation.

When the operator presses an inspection end button such as a switch, the second lever 5 returns to its original position as shown by the solid line in FIG. 1 or 3. Detect this reversion or
After a certain period of time after pressing the inspection end button, the third lever 7 returns to the solid line position shown in FIG. 1 or 4, but at this time, the inspected blank is transferred from the second lever 5 onto the third lever 7. , engages the stopper 8 and waits for the next release.

Effects of the Invention As described above, according to the inspection device of the present invention,
The operator simply selects an appropriate blank and activates the first lever, and the blank is automatically brought to a position where it can be easily inspected, and after the inspection is completed, the blank is automatically returned to the conveyor. During this time, you will not touch the blank at all, so it is not a safe length.
Accidents such as turning the blank in the wrong direction are completely eliminated.

Moreover, since the blanks are taken out above the conveyor as in this embodiment, a special space for an inspection device is not required, and the blanks can be placed as is on an existing line.
