Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a winding package inspection device.

[Conventional technology]

For example, before the next process of knitting and weaving, a package wound up in an automatic wine gourd is checked for defective shape by checking the amount of yarn wound.
This is done either by having an operator visually inspect the packages flowing on the conveyor one by one, or by directly measuring the weight of the packages using a scale during a sampling inspection.

[Problem that the invention seeks to solve]

According to the above-mentioned inspection by workers, when handling a large number of packages, it takes an extremely large amount of time to inspect all the packages, and even if the production speed of the wine goo increases with the advent of high-speed wine goo, the inspection will still be difficult. The process requires a lot of time and is inconvenient.

Furthermore, damage to the thread waste surface due to carrying the package,
Contamination etc. will reduce the quality of the product.

The present invention aims to solve the above problems.

Means for Solving Problem C] The inspection device of the present invention includes a rotating member that supports a package and rotates intermittently, one or more inspection mechanisms that are sequentially arranged at predetermined rotational positions of the rotating member, and It is composed of a package ejection mechanism and a mechanism for discharging good packages from the rotating member.

[Effect]

The package inserted into the package support part of the rotating member is automatically subjected to a first inspection or a second inspection every time the rotating member rotates intermittently, and any package that exceeds a set standard and is determined to be defective will be inspected. Only the packages that are discharged from the defective package discharge station and determined to be acceptable are automatically discharged from the inspection device and transported to the next process.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, the inspection device example includes a rotating member (31) that supports a package and rotates intermittently, a first inspection mechanism (3), a second inspection mechanism (33), which are arranged in order at each rotational position.

Average is placed.

The first inspection mechanism (9) is a weighing mechanism that inspects the weight of the package, which will be described later, and the second inspection mechanism is a winding inspection mechanism that checks the appearance of the thread layer of the package. The defective package ejecting mechanism (foundation) of the station (Sr3) is an example of an ejecting member that ejects packages determined to be defective in at least one of the inspections by the first and second inspection mechanisms from the normal package conveyance system; It is composed of a drive mechanism and the like of the member example. Further, the first and second inspection mechanisms pass both of them and pass the normal package transfer station (Sr1).
), the rotating member (
31) and transferred onto the tray (21A) of the conveyor α8.

Note that the supply of packages onto the rotating member (311) of the inspection station is automatically performed by a package delivery device or a robot (not shown).

Next, each mechanism will be explained in detail.

ii) Rotating member (3+) In Figs. 3 to 5, a vertical shaft (41) is supported via a bearing (39) fixed to a frame pole via a bearing GO), and a rotating member is attached to the upper end of the shaft (41). The member (311) is fixed.

As shown in FIG. 5, the rotating member (31) has package support begs (
42a) to (42d) to arm (43a) to (43
d), and each beg (42a
) ~ (42d) from the center of the axis (41), that is, the radius of rotation of the Veg is limited by the diameter of the package (PA) supported by the Veg or by various mechanisms, but at least the package is attached to each Veg. A distance is set so that adjacent packages do not interfere with each other when placed, and the intermittent rotational transfer time of the packages is minimized.

For example, the intermittent rotational drive of the above-mentioned rotating member is performed by the drive mechanism shown in Figure 4.5 (each station (STI) to (STI)
It is driven in synchronization with the processing mechanism in r1). m, a disk (46) having radial slide grooves (45a) to (45d) formed at 900 angles on the lower end surface is fixed with a key to the lower end of the shaft (41), and the drive camshaft (47) side A lever (49) that supports a roller (rear) that engages and disengages from the slide groove is fixed to the slide groove.
