Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] In the tile inspection process, the present invention selects tiles into three types such as non-defective products, defective products, and re-inspection required products, and these are different for each type. The present invention relates to a branching device for branching and transferring to a conveying unit.

[Conventional technology]

FIGS. 2 (a) to 2 (c) show an example of a conventionally used branching device. This branching device, for example,
Inspection sensor 80 for defects in the conveyed tiles t
It is used to classify the product into good products and defective products based on the result.

The schematic configuration and operation of the branching device will be described below with reference to the drawings. In the description of the conventional example, left and right are referred to with respect to the transport direction of the tile t (direction of arrow Q). That is, "right" means the upper side in FIG. 2 (a), and "left" means the lower side in FIG. 2 (a).

The branching device is provided with a right transporting unit 62 and a left transporting unit 63 that branch to the left and right in succession to the supply unit 61 of the tile t. Each of the supply means 61 and the left and right conveying means 62, 63 is composed of a combination of a belt and a pulley. At the center of the branch path 70 of the left and right conveying means 62, 63, a communication switching means 71 for connecting with the supply means 61 is provided. Here, of the pulleys 72, 78 and the belt 79 which connect the left and right conveying means 62, 63 and the supplying means 61, the supplying means 6
The support 73 of the pulley 72 on the side of 1 is connected to the pistons 74 and 76 of the electromagnetic cylinders 75 and 77 arranged in parallel, and is used as the switching means 71.

The tile t sent from the supply means 61 in the direction of arrow Q
Are inspected for defects by the inspection sensor 80. Depending on the presence or absence of a defect, one of the electromagnetic cylinders 75 and 77 arranged in parallel operates to extend the piston 74 (or 76). As a result, the supporting member 73 of the pulley 72 is tilted, for example, as shown in FIG. 2 (c), the pulley 72 is slightly moved to the left as shown by the arrow R in FIG. 2 (a), and the height of the pulley 72 is increased. The position is slightly higher. Therefore, the supply means
When the tile t which has entered the branching portion 70 from 63 reaches the pulley 72, it is guided to the left conveying means 62. Needless to say, when the electromagnetic cylinders 75 and 77 are operated in the opposite direction and the pulley 72 moves to the right, the tile t is sent to the left conveying means 63.

[Problems to be Solved by the Invention]

Although the conventional branching device is for distributing tiles in two directions, it may be necessary to branch tiles into three rows. For this reason, there has been proposed a device in which tiles are branched into three rows by applying the conventional branching device. Although not shown in the figure, a transport means is provided in the center in addition to the left and right transport means, and when the electromagnetic cylinder is in the inoperative state, the tile moves the central transport means,
When either one of the electromagnetic cylinders is activated, the tiles are sent to either the left or right conveying means.

However, in the tile three-row branch device manufactured using the electromagnetic cylinder, the following problems occur.

i. Since the operating speed of the electromagnetic cylinder is limited, the processing capacity to divide the tile into three rows has not been sufficiently satisfied.

ii. Since the electromagnetic cylinder must be installed in a narrow space around the transportation means, the mounting work is difficult and the maintenance is complicated.

iii. Electromagnetic cylinder There is a high possibility that self-confidence will cause malfunctions, and it will be difficult to ensure the sorting process.

[Means for Solving the Problems]

The present invention is a novel three-row branching device devised in view of the above-mentioned problems, which is characterized in that a central conveying means and conveying surfaces to the left and right of the central conveying means are conveyed by the central conveying means. Left transport means and right transport means provided at a position lower than the plane, tilt transfer means for connecting the branch portion provided in the central transport means and the left and right transport means, and the branch portion of the central transport means. On the left and right sides of the compressed air jetting means arranged so as to oppose to a position slightly above the transfer surface, and the inclined transfer means has a transfer surface at a position lower than the transfer surface of the central transfer means. And a round belt or V stretched so as to descend near the side edge portions of the central conveying means from the branch portion of the central conveying means to the introduction portions of the left and right conveying means. Consists of a belt and It is when.

[Action]

The tiles that have been transported to the branching device according to the above configuration are
At the branch portion of the central transport means, the transport direction is selected. For example, in order to transfer the tile to the left conveying means, the compressed air is ejected toward the right side surface of the tile from the ejecting means on the right side of the ejecting means for the compressed air provided on both the left and right sides of the branch portion. The pressure of the compressed air causes the tile to move to the left with respect to the central carrier.
As a result, the center of gravity of the tile also moves to the left, so that the tile is tilted, and the left edge on the back surface is first landed on the horizontal belt of the tilt transfer means. When the tiles are further transported, this time, the vicinity of the right edge on the back surface of the tiles is stretched so as to descend from the branch portion of the central transportation means to the introduction portion of the left transportation means. It is supported by a round belt or a V-belt, is conveyed in this state, and eventually reaches the introduction part of the left conveying means. In this way, the transfer of tiles to the left transport means is completed.

When transferring the tiles to the right conveying means, on the contrary to the above, compressed air may be ejected from the left ejection means toward the left side surface of the tiles, and when the tiles are delivered to the central conveying means. It is not necessary to inject compressed air.

〔Example〕

Hereinafter, details of the present invention will be described with reference to the drawings illustrating an embodiment.

FIG. 1 (a) is a plan view showing a branching device according to the present invention, and FIG. 1 (b) is a vertical cross-sectional side view taken along line XX of FIG. In the drawings, 1 is a central conveying means, 2 is a right conveying means, 3 is a left conveying means, 4 is an inclined transfer means, and 6 is a tile supply means, each of which is composed of a combination of a belt and a pulley. There is. Reference numeral 5 is a jetting means for compressed air, 7 is a branching portion, T, T ₁ , T ₂ , T ₃ , T ₄ and T ₅ are tiles, and 13, 14 and 15 are drive sources for the conveying means. In the description of this embodiment, the left and right means the left and right in the tile conveying direction (direction of arrow P). That is, the upper side in FIG. 1A is “right” and the lower side is “left”.

As shown in the drawing, the supply means 6 for the tile T and the central conveying means 1 are continuous. A portion 11 of the central conveying means 1 following the supply means 6 is a narrow flat belt, and is a downstream conveyer composed of two van cords (registered trademark / product name of Bando Kagaku Co., Ltd.) stretched in parallel. Means main part 10
Connected to. Left and right slanting transfer means 4, 4 branched from a branching part 7, and right and left transfer means 2 and 3 are provided on the left and right sides of the central transfer means 1, respectively. The left and right transportation means 2 and 3 are the transportation means main portions 20 and 30 composed of two bancodes stretched in parallel with each other, and the bancodes which are installed immediately before these introduction portions and which perform the inclination transfer means. It is composed of the connecting portions 21 and 31.
The inclined transfer means 4, 4 connecting the central transport means 1 and the left and right transport means 2, 3 to each other, the horizontal belt 4 starting from the branching portion 7 provided at a position where the transport surface is lower than the transport surface of the central transport means 1.
0 and 42, and the branch portion 7 near the left and right side edges of the central conveying means 1.
From the position slightly downstream from the main part 2 of the left and right conveying means 2, 3
It is composed of a round belt such as a van cord or V belts 41 and 43 stretched so as to gently descend to the introduction portion of 0 and 30. Further, on both left and right sides of the branch portion 7, jetting means 5 (50, 51) for compressed air are provided so as to face each other. The position of the ejection port 5a of the ejection unit 5 is slightly higher than the conveyance surface of the central conveyance unit 1.

The tile T supplied from the supply means 6 to the branching device is
First, it is conveyed by the flat belt portion 11 of the central conveying means 1 and enters the branch portion 7. When the compressed air jetting means 5 is not operated, the tile T is directly carried out from the flat belt 11 to the conveying means main portion 10.

When the tile T is transferred to the left conveying means 3, compressed air is jetted from the jetting means 50 on the right side to the right side surface of the tile,
Tilt the tile (T ₁ ) as shown. At this time, the magnitude of the air pressure, the spray position, etc. are appropriately determined in relation to the tile size and the distribution angle. In the present embodiment, a so-called 100 square (a plane shape is a square having a side of 100 mm) and a thickness of 5 mm, a compressed air having a pressure of 4 kg / cm ² from a jet outlet having a diameter of 1 to 2 mm is applied to the tile. It spouts from the front end to a place that is approximately one-third the length.

Since the center of gravity of the slanted tile T ₁ is shifted to the left from the transport surface of the central transport means 1, the tile T ₁ is slanted like the tile T ₂ and the left edge of the back surface is inclined by the horizontal belt 40 of the slant transfer means 4. Land on. When this state is further moved in the transport direction, the vicinity of the right side edge portion on the back surface of the tile is supported by the round belt such as a van cord or the V belt 41 this time. Therefore, as shown in T ₃ and T ₄ , the tile is supported by the horizontal belt 40 at the left edge of the back surface and the round belt or the V belt 41 at the vicinity of the right edge of the tile in a tilted state. Is transported to the introduction section of. The tile T ₅ that has reached the main part 30 of the left transporting means is carried out to the next step.

On the contrary to the above, in order to send the tile T to the right conveying means 2, compressed air may be jetted from the left jetting means 51 toward the left side surface of the tile.

By the way, the branching device is used when the tiles are sorted into three types. As an example, in an inspection process using two inspection sensors, a sensor in which neither of the two sensors detected a defect is a good product, one in which two sensors have detected a defect is a defective product, and only one sensor has a defect. For example, it is possible to judge the detected items as re-inspection-required items and select them. In this case, a control valve is provided in the middle of the pipe 52 for supplying the compressed air from the supply source 55 to the ejection means 5.
54, and a controller 56 for operating the operation of the valve 54 based on a signal from the inspection sensor may be installed.

It is needless to say that the embodiments of the present invention are not limited to the above-mentioned modes and various applications are possible.

〔The invention's effect〕

The branching device according to the present invention exhibits excellent effects as listed below.

Since compressed air is used as a means for allocating tiles, not only the control is simple, but also the sorting capacity is greatly improved. When the electromagnetic cylinder was used as in the past, the processing speed of 100 square tiles was about 230 sheets per minute. On the other hand, according to the present invention, a processing speed of about 270 sheets per minute can be obtained. That is, it is possible to increase the number of processed sheets of 40 sheets per minute and 2400 sheets per hour.

When the compressed air is used according to the present invention, the tile distribution angle can be made larger than that when the conventional electromagnetic cylinder is used. Therefore, it is possible to shorten the distance required from the branch portion of the transport means to the main portion of each transport means. In the past, the distance from the branch portion to the main portion was required to be 1500 mm or more, but according to the above-mentioned embodiment of the present invention, this can be made only 980 mm.

The compressed air jetting means may employ a configuration in which the compressed air supply source and the jet outlet are connected by a pipe. Therefore, it is possible to easily install the jetting means even in the vicinity of the transfer facility where the installation space is not very large.

The compressed air ejecting means has a simpler structure than that of the conventional electromagnetic cylinder, so that there is less risk of malfunction and maintenance is easy.

Since the inclined transfer means is composed of a horizontal belt and a round belt such as a van cord or a V-belt, the tile has one side edge on the back surface until it reaches the left or right conveyance means from the central conveyance means. Is conveyed while being held in an inclined state in which the surface of the belt is brought into contact with the surface of the horizontal belt at an angle. For this reason, since the frictional force acting between the tile and the horizontal belt is large, the tile is unlikely to slip on the horizontal belt and the positional deviation is very unlikely to occur.
