Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an article conveying device, and relates to an article conveying device that changes the direction of an article carried in from one side in a different direction and conveys it to the other side.

Hitherto, various structures have been proposed as this type of distribution mechanism, but the first one generally has a special direction change mechanism in the direction change section, and the goods transported by this direction change mechanism are Many of them have a structure in which the material is turned in the other direction and then transported out.

However, these types of devices tend to have a complicated structure and high cost, and in some cases, there are problems such as the possibility of objects getting stuck at the turning point or being transferred in an inclined position. have.

The present invention was developed in view of the above points, and it is possible to constantly transport goods without using a complicated direction change mechanism, without congesting the change direction with goods, and without having to transfer goods in an inclined position. It is an object of the present invention to provide an article conveying device that can smoothly change direction and convey.

The present invention includes a plurality of high-speed rotating rows 2 arranged in parallel on a frame with shafts for carrying out articles at high speed, and at least a carrying-in section of the high-speed rotating rollers arranged in a direction perpendicular to the carrying-out direction of the articles. a transport conveyor, which is connected with the transport surface forming a slightly lower head than the transport surface of the high-speed rotation roller and is driven at a slower speed than the high-speed rotation roller; Located at the outer end of the conveyor's loading section, it locks the articles being carried out by high-speed rotating rollers when changing the direction of the articles and conveying them, and the conveyor also changes the direction of the articles in the orthogonal direction and conveys them. The stopper is integrated with a stopper that moves forward and backward with respect to the inlet section of the conveyor, and extends only when the article is to be conveyed without changing the orientation of the article. The present invention is characterized by comprising a guide body that guides the conveyor.

Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a frame, and high-speed rotating rollers 3 for transporting articles at high speed are rotatably mounted on parallel mounting pieces 2 of the frame 1 at predetermined intervals.

The plurality of high-speed rotation rollers 3 are driven at high speed via an electric motor and an interlocking mechanism (not shown).

4 is a carry-in conveyor, and this carry-in conveyor 4 is connected to the article carry-in section 5 of each of the high-speed rotating rollers 3.

This carry-in conveyor 4 is rotated at a speed slower than the rotational speed of each high-speed rotating roller 3 by a driving means (not shown).

Further, reference numeral 6 denotes a conveyor, and this conveyor 6 is disposed at the unloading section 7 of the high-speed rotating roller 3 so as to be orthogonal to the article unloading direction of the high-speed rotating row 23.

In this conveyor 6, mounting pieces 8 and 9 are opposed to the frame 1 in the same direction as the high-speed rotating row 23, and a large number of rollers 10 are rotated at a predetermined gap between the mounting pieces 8 and 9. This large number of rollers 1 are freely arranged in parallel
It consists of 0.

Further, drive rollers 11 are rotatably mounted on a shaft at both ends in the conveying direction, located under one mounting piece 9 of the frame 1, that is, below each of the rollers 10, and between the drive rollers 11. A drive belt 12 is suspended and engaged with the lower surface of each of the rows 210, so that each row 210 is rotated in conjunction with the article conveyance direction by frictional coupling of the drive belt 120 times. It has become.

The one drive roller 11 is driven by a drive means (not shown) at a speed slower than the rotational speed of the high speed rotation roller 3 via an interlocking mechanism 13 connected thereto.

Then, the transport surface a of at least the inlet section of the transport conveyor 6 constituted by the above-mentioned rows 210 is slightly lower than the transport surface constituted by the high-speed rotating rollers 3, for example, due to the lower head of about 20 mm, the goods are transported. It is designed to prevent splashing.

The housing 14 is integral with a stopper, and the integral stopper 14 is approximately the same length as the high-speed rotating roller 3 and has a U-shaped cross section, with connecting rods 15 protruding from both ends thereof.

This integral stopper 14 is fixed to a supporting frame 16 via connecting rods 15 at both ends, and the supporting frame 16 is located outside the carrying-in part of the conveyor 6 in front of the carrying-out part 7 of the high-speed rotating roller 3. It is located and fixed at the end.

Reference numeral 17 denotes a guide body, and this guide body 17 is curved with an arcuate guide surface 18 having a large curvature formed inside.

One end of the guide body 17 is fixed to a support shaft 19, and the support shaft 19 is rotated by the frame 1 at one end in the width direction of the unloading section 7 of the high-speed rotating row 23, that is, at the outer end. It is freely erected.

Further, a piston rod 22 of a cylinder 21 is rotatably connected to a lever 20 fixed to this support shaft 19, and this cylinder 21 is fixed to the frame 1.

Then, by the expansion and contraction of the piston rod 22 of the cylinder 21, the support shaft 19 is rotated via the lever 20, and the guide body 17 fixed thereto is inserted into the loading section of the conveyor 6.
That is, it moves forward and backward in front of the stopper unit 14.

Next, a fixed guide 23 is provided at the other end in the width direction of the unloading portion 7 of the high-speed rotation roller 3, that is, at the inner end,
The inner surface of this fixed guide 23, that is, the guide body 1
An arcuate guide surface 24 is formed on the surface opposite to the guide surface 7 .

In the past, the stopper unit 14, the fixed guide 23, and a series of guide pieces 25 were fixed to both ends of the conveyor 6 in the width direction.

In this structure, when an article is carried into the carry-in section 5 of the high-speed rotating rollers 3 by the carrying-in conveyor 4, the conveyance speed of the article is increased by the high-speed rotating roller 23, and the article is transported to the carrying-out section T. At the same time, it is further carried out vigorously from the carrying-out section 7 to the carrying-in section of the conveyor 6.

In this case, the transfer surface a of the carry-in section of the conveyor 6 is lower than the transfer surface of the high-speed rotating rollers 3 and has a certain height difference, so that the articles are carried into the carry-in section of the conveyor 6 in a floating state. Ru.

In addition, since a stopper unit 14 is provided at the outer end of the conveyor 6 in front of the unloading section 7 of the high-speed rotation roller 3, articles that are being carried out with great force can be prevented by stopping at the stopper unit 14.
4, the load is reliably locked, and the load is transported with the direction changed.

In addition, even if the article bounces back toward the high-speed rotation roller 3 side due to momentum, the difference in level between the transfer surface a of the carry-in section of the conveyor 6 and the transfer surface of the high-speed rotation roller 3, i.e. There is no possibility of running onto the high speed rotating roller 3 side due to the drop.

The articles carried into the carrying-in section of the conveyor 6 are
The conveyor 6, which is previously rotated at a slower speed than the high-speed rotating rollers 3, changes direction and is conveyed toward the discharge section.

Therefore, each article that is continuously conveyed from the carry-in conveyor 4 is separated from the following articles by the high-speed rotating rollers 3 and carried out, and the direction can be changed without causing traffic jams and smoothly conveyed by the conveyor 6. .

Next, when transporting articles without changing the load direction, the cylinder 21 is operated and the piston rod 22 is contracted as shown in FIG. The guide body 17 fixed to the support shaft 19 is advanced to a predetermined position of the loading portion of the conveyor 6 in front of the integral stopper 14.

When the article is carried out with great force by the high-speed rollers 3 as described above, the article is guided by the arc-shaped guide surface 18 inside the guide body 17 and is conveyed by the conveyor 6 without changing the direction of the article. .

Further, at this time, the article is conveyed by the conveyor 6 while being guided by the guide surface 24 of the fixed guide 23 together with the guide body 17 depending on the case.

In addition, in implementation, it is preferable to use a roller with a large friction coefficient as the high-speed rotating roller 3.

Further, the conveyor 6 includes a plurality of rollers 1 that constitute the conveyor 6.
0, for example, lining roller I on row 210 in the middle.
It is preferable to intervene with Qa.

According to the present invention, a plurality of high-speed rotating rollers are installed in a parallel shaft, and the article is transported at a height slightly lower than the transfer surface of the high-speed rotating rollers, perpendicular to the article discharging direction, at the article discharging section of the high-speed rotating rollers. By arranging conveyors with a surface formed in series, it is possible to receive the incoming articles with a simple structure of high-speed rotating rollers without using a special complicated direction change mechanism, and to transfer the articles to the inlet section of the conveyor. Therefore, there is no risk of objects becoming jammed at the direction change section or being transferred to the conveyor's input section in an extremely tilted state. By installing a stopper integrally at the outer end of the carry-in section of the carry-in conveyor, even if the article is carried out forcefully by the high-speed rotating rollers, the stopper will surely stop the article from being received, and the rotation of the conveyor will be prevented. Together with this, it is possible to change the direction of the load and convey it smoothly, and also because the transfer surface of at least the carry-in section of this conveyor is lower than the transfer surface of the high-speed rotating rollers, forming a slight head. , it is easy to transfer the article to the loading section of the loading conveyor, and even if the article is pushed back toward the high-speed rotating rollers, this can be reliably prevented by the step. Moreover, by providing the guide body so that it can move forward and backward with respect to the loading section of the loading conveyor, by using the guide body, it is possible to smoothly convey the load without changing the direction of the load, and therefore,
It is possible to change the direction of the goods or to smoothly change the direction of the goods and carry them out without changing the direction of the goods.
