Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a continuous inspection device that continuously inspects objects to be inspected.

[Prior Art] As this type of continuous inspection device, there is, for example, one that continuously inspects cartridges. As an example of this inspection device, as disclosed in Japanese Patent Application Laid-open No. 58-80630, a holder for holding a cartridge is provided on an index table, and an inspection means is installed independently around the index table. There is a device that is fixedly arranged and uses this inspection means to inspect cartridges that are intermittently conveyed by an index table.

[Problems to be Solved by the Invention] Incidentally, in such a continuous inspection device, since the cartridge being transported is inspected by an independently fixed inspection means, the carriage of the cartridge may be temporarily stopped for inspection. Need to stop. For this reason, the cartridges are transported intermittently, and there is a certain limit to the inspection speed, which is one of the causes of a reduction in throughput, especially when a large number of cartridges are inspected continuously.

For this reason, it is conceivable to inspect the cartridge while transporting it using a transport means such as a conveyor, but when transporting the cartridge using a transport means such as a conveyor, regulating the position of the cartridge is especially important. If there is any wobbling, it will affect the inspection accuracy and cause problems such as not being able to perform accurate inspections.

This invention was made in view of the above circumstances, and provides a continuous inspection device that eliminates the need for pauses during inspection, improves inspection speed, increases throughput, and improves inspection accuracy. It is intended to.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a continuous inspection device that continuously and automatically inspects objects to be inspected, including an endless conveyor holder that holds the objects to be inspected. a conveying means, a rotational drive means provided on a drive shaft that provides a driving force to the endless conveyance means, a positioning holder guide arranged around the endless conveyance means driven by the rotational drive means and guiding the conveyance holder; holder holding means provided on the rotation drive means to engage and hold the transport holder; a rotation inspection turret provided on the drive shaft and rotating in synchronization with the rotation drive means; and a rotation inspection turret provided on the rotation inspection turret for transport. The present invention is characterized by comprising an inspection means for inspecting an object to be inspected.

[Function] In the present invention, the endless conveyance means is provided with a conveyance holder, and the endless conveyance means is conveyed by applying a driving force with the rotation drive means provided on the drive shaft, and the inspected object held in the conveyance holder is conveyed. Continuously transport.
The transported object to be inspected is inspected by an inspection means provided on a rotary inspection turret that rotates in synchronization with the rotation drive means. At this time, the transport holder is guided by the positioning holder guide arranged around the endless transport means, and the holder holding means provided on the rotation drive means engages and holds the transport holder, so that the object to be inspected is The inspection accuracy of the inspected object is improved by transporting the inspected object in a securely regulated position.

[Embodiment] Next, an embodiment in which the present invention is applied to an automatic cartridge supply device will be described in detail with reference to the accompanying drawings.

In the figure, code 1 is the drive shaft of the continuous inspection device.
A rotation inspection turret 2 and a sprocket 3 serving as rotation driving means are provided on the drive shaft 1 so as to be integrally rotatable. A chain 1, which is an endless conveyance means, meshes with the sprocket 3, and the chain 4 is provided with a plurality of conveyance holders 6, which hold cartridges 5, which are objects to be inspected, at predetermined intervals.

An insertion rod 7 is provided in the receiving portion 6a of the transport holder 6, and the lower end of a spool provided on the cartridge 5 is inserted into the insertion rod 7, thereby holding the cartridge 5.

Holder guides 8 and 9 are provided on both sides of the chain 4.
are respectively arranged, and a holder guide 10 is similarly provided on the upper surface of the sprocket 3,
These holder guides 8, 9, and 10 are all on the same surface. Further, in the inspection area around the sprocket 3, a positioning holder guide 11 is arranged above the holder guide 9 and close to the side surface of the conveying holder 6.

rollers 12 arranged on both sides of the conveyance holder 6;
13 runs on these holder guides 8 and 9, and positions the transport holder 6 in the vertical direction.

A bracket 14 constituting the holder holding means A is fixed to the sprocket 3, and this bracket 1
A pair of arms 14a and 14b are supported at the tips of the arms 4. Positioning rollers 15 and 16 are supported by the arms 14a and 14b, and the positioning rollers 15 and 16 and the positioning holder guide 11 support the side surfaces of the transport holder 6 at three points to regulate the horizontal position of the transport holder 6. will be carried out.

An inspection means 17 is mounted on the rotating inspection turret 2, and this inspection means 17 moves in synchronization with the transport holder 6 and faces the cartridge 5 held by the transport holder 6.

There are various types of inspection means 17, such as one for inspecting irregularities on the side surface of the cartridge 5, and one for detecting the length of the cartridge 5 in the axial direction.

Next, the operation of this embodiment will be explained.

When the rotating shaft 1 of the continuous inspection device rotates, the rotating inspection turret 2 and sprocket 3 rotate together,
The chain 4 is driven by this rotation of the sprocket 3, and the transport holder 6 fixed to the chain 4 is transported. The cartridge 5 is delivered to the transport holder 6 at a predetermined position by a supply device (not shown), and carried into the inspection area around the rotating inspection turret 2.

In this inspection area, the inspection means 17 provided on the rotary inspection turret 2 performs inspection while moving in synchronization with the transport holder 6 by the rotation of the drive shaft 1. Therefore, the inspection means 17 completes the inspection while the cartridge 5 is being transported.

Therefore, the inspection means 17 continuously inspects the cartridge without stopping its transport.

When transporting the transport holder 6, the transport holder 6 tends to shake due to the play between the sprocket 3 and the chain 4, but the rollers 12 and 13 provided on the transport holder 6 move over the holder guides 8, 9, and 10. By traveling, the position in the vertical direction is regulated. In addition, in the inspection area, the arm 14 of the bracket 14 provided on the sprocket 3
Positioning rollers 15 and 16 provided on a and 14b
and the positioning holder guide 11 to transport the transport holder 6.
The horizontal position is regulated by supporting at three points.

[Effects of the Invention] As described above, the present invention moves the rotating inspection turret in synchronization with the endless conveying means, and inspects the object to be inspected while conveying it using the inspection means provided on the rotating inspection turret. This eliminates the need for pauses during inspection, improves inspection speed, and increases processing capacity.

In addition, the transport holder is guided by the positioning holder guide arranged around the endless transport means, and the holder holding means provided on the rotational drive means engages and holds the transport holder, so the object to be inspected is securely held. The inspection accuracy of the inspection object is improved because the inspection object can be transported with its position regulated, and the inspection object does not wobble during transportation.
