Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an article conveying device, and for example, when cleaning oil, dust, etc. adhering to an article such as a coil spring during manufacturing, it is necessary to remove cleaning liquid from the coil spring after cleaning and conveying the article. This article relates to an article conveying device that enables simultaneous and continuous operations, or evenly applies treatments such as heating, and minimizes the installation floor space of the conveying device itself. .

Conventionally, belt conveyor-like devices have generally been used as conveyance devices, but the length of belt conveyor-like devices is determined by the length of the process required to perform the work and the distance traveled. Even if the distance to be transported is short, a length corresponding to the working process is required, which inevitably results in a large installation floor area.

In addition, since the articles placed on the belt conveyor do not move in relation to the belt conveyor, when the articles are subjected to treatments such as washing or heating, the parts that have been sufficiently treated and the areas that have not been There was a risk that some parts would be insufficient.

Therefore, Japanese Patent Publication No. 50-13987 proposed a device for automatically supplying a certain amount of abrasive grains to a resinoid grinding wheel as a structure for uniformly carrying out the above-mentioned processing and having a small installation area. , this device rotates abrasive grain scraping blades on a horizontal axis to scrape up abrasive grains, and drops the abrasive grains onto a conveying means with one end passing longitudinally through the center of rotation, and
(The abrasive grains are automatically supplied by the conveying means.

Therefore, for example, when removing oil and dust adhering to the surface of a coil spring, the coil spring is immersed in Tri-Clean solution to clean the oil and dust. In order to dispose of the tri-clean liquid containing oil and dust while conveying the springs one after another, it is necessary to separate the tri-clean liquid from the coil spring and dry it. It is impossible to drain the liquid as it falls into the conveying device together with the coil spring, and furthermore, it has drawbacks such as being prone to scratches on the items because it is scooped up and dropped into the conveying device. For,
With a device having such a structure, it has been impossible to continuously transport the triclean solution containing oil and dust adhering to the surface of the coil spring, etc., while discarding it.

This invention was created in view of the above-mentioned points, and its gist is that a rotary cylinder that rotates about a substantially horizontal rotation axis and has a tapered inner periphery is provided inside a sealable outer shell. A rising wall of an appropriate width is provided at both inner circumferential ends of the rotary cylinder in the direction of the center force over the entire circumference, and inside the rotary cylinder there are walls extending from the inner circumference of the rotary cylinder toward the center and above. A plurality of partition walls are provided approximately evenly in parallel with the axial direction of the shaft, and an internal taper unit that rotates together with the rotating cylinder by the shaft and has a tapered outer periphery is provided, and a small diameter portion on the outer periphery of the taper unit is provided. It is located at the large diameter side end of the rotating cylinder and is fixed to the partition wall to appropriately partition the space between the inner periphery of the rotating cylinder and the outer periphery of the integrated internal taper, and is connected to the outer periphery of the large diameter part of the integrated internal taper and the inside of the rotating cylinder. A gap is provided between the outer periphery of the small-diameter part integrated with the internal taper and the large-diameter side rising wall of the rotary cylinder through which the articles to be conveyed can pass, and the large-diameter side of the rotary cylinder is connected to the outer shell. A rotating cylinder is disposed at least close enough to the side wall surface of the body to prevent the article from falling, and the side wall surface of the outer shell has an outer periphery of the small diameter part integrated with the internal taper and a rising wall on the large diameter side of the rotating cylinder. A discharge port for the article is provided at a position facing the gap between the two and slightly lower than the top of the gap, and an introduction path for the article is provided below the outer shell body and inside the rotary tube on the small diameter side of the rotating tube. This is due to the fact that the

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

That is, in the figure, reference numeral 1 denotes a sealable outer shell, and a rotary cylinder 3 having a tapered inner periphery is accommodated within this outer shell 1.

A rising wall 6 of an appropriate width is provided along the entire circumference toward the center at both inner peripheral ends of the rotary cylinder 3, and an opening 5 is formed at each end.

Furthermore, inside the rotary tube 3, there are a plurality of holes that are approximately evenly distributed from the inner periphery of the rotary tube 3 toward the middle direction, and that are approximately parallel to the axial direction of the rotary shaft 2, which will be described later, that rotates the rotary tube 3. A partition wall 8 is provided.

Further, inside the rotary cylinder 3, there is provided a dish-shaped internal taper unit 9 with a tapered outer circumference and a bottom surface 29 at the end of the small diameter portion 10, and a rotary shaft 2 erected at the center of the bottom surface 29. The small diameter portion 10 of this tapered integral body 9 is arranged as the large diameter side 30 of the rotary cylinder 3 so that its bottom surface 29 is at the same position as the rising wall 6 provided at the end of the large diameter side 30, and the inner circumference of the rotary cylinder 3 is The partition wall 8 and the outer periphery of the internal taper unit 9 are fixed in a state where the outer periphery of the internal taper unit 9 and the inner periphery of the internal taper unit 9 are concentric, and as a result, the distance between the inner periphery of the rotary cylinder 3 and the outer periphery of the internal taper unit 9 is This partitions the space and allows both the rotating cylinder 3 and the internal taper unit 9 to rotate around the substantially horizontal rotating shaft 2.

Moreover, the outer periphery of the large diameter portion 11 of the internal taper integral 9 and the rotary cylinder 3
Between the inner periphery and the outer periphery of the small diameter portion 10 of the internal taper unit 9 and the rising wall 6 of the large diameter side 30 of the rotary cylinder 3, 1 provides gaps 7 and 13 through which the articles 19 to be conveyed can pass. , the rotating tube 3 is disposed so that the large-diameter side 30 portion of the rotating tube 3 approaches the side wall surface 14 of the outer shell 1 at least to the extent that the article 19 to be conveyed does not fall, thereby reducing the internal taper. The bottom surface 29 of the integral body 9 is also close to the side wall surface 14.

On the other hand, on the side wall surface 14, there is a position facing the gap 7 between the outer periphery of the small diameter portion 10 of the internal taper unit 9 and the rising wall 6 on the large diameter side 30 of the rotary cylinder 3, and from the top of the gap 7. The outlet 15 for the article 19 is provided at a slightly lower position, that is, at a position shifted, for example, to the right from the apex on the circumference of the gap 7 as shown in FIG. An introduction path 16 for the article 19 is provided from the shell 1 toward the lower part of the rotary cylinder 3.

Opening/closing doors 1 are provided at the discharge port 15 and the introduction path 16, respectively.
7.18, which automatically open by the weight of the article 19 when the article 19 to be conveyed passes through the discharge port 15 and the introduction path 16, and automatically close by their own weight or a weak spring after passing through. There are formal precepts.

Next, when this is activated, the article 19 to be conveyed is introduced into the rotary tube 3 from the introduction path 16 through the opening 5 while rotating the rotary tube 3, and the article 19 is transferred to the large diameter portion of the internal taper integral body 9. 11 and the inner periphery of the rotating cylinder 3, and settles on the large diameter side 30 inside the rotating cylinder 3 and on the partition wall 8 side on the forward side of the movement, and the rotating cylinder 3 rotates while shaking. Therefore, as the rotary cylinder 3 rotates, the article 19 moves toward the partition wall 8 on the moving front side on the large diameter side 30 inside the rotary cylinder 3.
Move from the side toward the partition wall 8 on the rear side.

When the rotary cylinder 3 further continues to rotate, the partition wall 8 becomes horizontal and further tilts so that the outer side faces upward.

As a result, the article 19 that has been present on the inner circumferential wall side of the rotary cylinder 3 moves along the partition wall 8 in the direction of the internal taper unit 9.

At this time, the article 1 is placed in the small diameter portion 10 of the internal taper unit 9.
There is a gap 7 through which the article 19 can pass, but this gap 7 is closed by the side wall surface 14 of the outer shell 1, so the article 19 moves while touching the side wall surface 14.

When the article 19 is conveyed to the position of the discharge port 15 provided on the side wall surface 14, the internal taper 9
The article 19 automatically moves toward the outlet 15 and is taken out from the outlet 15 due to the inclination of the article 19 .
