Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a transport device capable of branching a transported object and controlling the attitude of the transported object. This transport device is particularly suitable for transporting rectangular transport objects.

[0002]

[Prior art]

 A special branching device was installed when it was necessary to branch a conveyed product in the conventional transporting device. Also, when it was necessary to control the attitude of the conveyed goods, a special attitude control device was installed.

[0003]

[Problems to be solved by the invention]

 When a special branching device or attitude control device was installed, the device became complicated and expensive. The problem to be solved by the present invention is to provide a transfer device that can branch a transfer object and control the posture of the transfer object without attaching a special device.

[0004]

[Means for Solving the Problems]

 The conveying device according to claim 1, the second conveyor 2 is arranged in series on the discharge side of the first conveyor 1, the third conveyor 3 is arranged in series on the discharge side of the second conveyor 2, and the second conveyor 2 is When the second conveyor 2 is rotated horizontally so that it can be rotated horizontally, the fourth conveyor 8 is arranged in a direction that is in series with the discharge side of the second conveyor 2, and an angle is set to the discharge side of the fourth conveyor 8. In addition, the fifth conveyor 9 is arranged. When transporting the transported product straight, the first conveyor 1, the second conveyor 2, and the third conveyor 3 are transported in series. When branching the conveyed material, the second conveyor 2 is turned horizontally and conveyed in series with the fourth conveyor 8.

According to a second aspect of the present invention, in order to enable the second conveyor 2 to be rotated horizontally, a discharge end of the first conveyor 1 and a carry-in end of the second conveyor 2 are provided. A support 4 for filling a gap provided therebetween is provided substantially flush with the second conveyor 2. If there is a gap, the conveyed product may be caught in the gap and may not be transported smoothly. This is not the case in the second aspect.

According to a third aspect, in the first aspect, the frame 11 having the upper surface slightly higher than the upper surface of the driving roller 12 or the like, which is the carrier of the fifth conveyor 9, is provided on both sides of the fifth conveyor 9. The distance between the inner surfaces of the frames 11 is narrower than the long side of the rectangular article to be conveyed and wider than the short side. Regardless of the posture of the rectangular conveyed object on the fifth conveyor 9, the posture of the conveyed object may be corrected due to the corners of the conveyed object colliding with the frame 11 while being conveyed on the fifth conveyor 9. It is discharged in a posture.

According to a fourth aspect, in the first aspect, a gap formed between a discharge end of the fourth conveyor 8 and a side edge of the fifth conveyor 9 is filled with the gap. The driving speed of the group of driving rollers 10 is made higher than the feeding speed of the fifth conveyor 9. If there is a gap, a part of the conveyed product may fall into the gap, preventing smooth continuous conveyance. If there is a group of drive rollers 10 that fills the gap, it can be transported smoothly. Further, since the transport speed of the drive roller 10 group is high, when the transported material is thrown from the drive roller 10 group onto the fifth conveyor 9, if the transported material is not in a predetermined posture, the corners are framed. The posture is controlled due to collision with the object, and is discharged in a predetermined posture.

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to FIGS. 1 is a plan view, FIG. 2 is a plan view of main parts, FIG. 3 is a front view of main parts, FIG. 4 is a front view, and FIG. 5 is a plan view of main parts. As shown in FIG. 1, a second conveyor 2 such as a belt conveyor is arranged in series on the discharge side of a first conveyor 1 such as a belt conveyor, and a third conveyor 3 such as a belt conveyor is disposed on the discharge side of the second conveyor 2. They are arranged in series. As shown in FIG. 2, the second conveyor 2 can be rotated clockwise in the horizontal direction by about 45 degrees around a rotation center A provided at the center near the carry-in side. By the way, in order to enable the second conveyor 2 to rotate, the first conveyor 1 must be so rotated that the corner B on the loading side of the second conveyor 2 does not contact the discharge end of the first conveyor 1 when rotating. It is necessary to provide a sufficient gap between the first conveyor 2 and the second conveyor 2. However, if such a gap is provided, a part of the conveyed article may fall into the gap and hinder smooth continuous conveyance.

Therefore, a measure as shown in FIG. 2 was taken. First, a support 4 was attached along the end of the second conveyor 2 on the carry-in side, and was substantially flush with the second conveyor 2. The front end of the support 4 is provided with an arc portion 5 having a radius equal to the length connecting the rotation center A and the corner B by 90 degrees from the corner B, and the rest is a straight portion 6 parallel to the carry-in end. Shaped. Also, a triangular support 4 was attached along the side edge from the corner B of the second conveyor 2. The front edge of the triangular support 4 is a straight portion 7 extending tangentially from the arc 5. As is apparent from FIG. 1, when the support 4 is formed in such a shape, even if the first conveyor 1 and the second conveyor 2 are connected in series, the second conveyor 2 is rotated and inclined. However, the gap between the first conveyor 1 and the second conveyor 2 is almost completely filled with the support 4.

A fourth conveyor 8 such as a belt conveyor is arranged in a direction in which the second conveyor 2 is in series with the discharge side of the second conveyor 2 when the second conveyor 2 is rotated by approximately 45 degrees. On the discharge side of the fourth conveyor 8, a fifth conveyor 9 such as a roller conveyor is disposed in a direction inclined at about 45 degrees. Since the fourth conveyor 8 and the fifth conveyor 9 are arranged at an angle of about 45 degrees, a triangular gap is formed between the discharge end of the fourth conveyor 8 and the side edge of the fifth conveyor 9. ing. In order to fill the gap, several drive rollers 10 are provided in parallel from the longest one to the shortest one. The transport speed of the drive rollers 10 is set to be higher than the transport speed of the fifth conveyor 9.

Although the fifth conveyor 9 may be a belt conveyor, as shown in FIG. 3, a plurality of drive rollers 12 may be mounted in parallel between left and right frames 11 arranged in parallel. . However, the upper surface of both frames 11 is higher than the upper surface of the carrier such as the drive roller 12 by a height h of several centimeters. A sixth conveyor 13 such as a belt conveyor is arranged in series on the discharge end side of the fifth conveyor 9. By the way, in the above, the configuration is as shown in FIG. That is, the discharge end of the first conveyor 1 is slightly higher than the carry-in end of the second conveyor 2, the discharge end of the second conveyor 2 is slightly higher than the carry-in end of the fourth conveyor 8, and the discharge of the fourth conveyor 8 is performed. The discharge end of the group of drive rollers 10 arranged on the end side is slightly higher than the upper surface of the frame 11 of the fifth conveyor 9. By doing so, the movement of the conveyed goods becomes smooth.

The above-described transport device operates as follows. For example, assume that a rectangular transport object H is transported. However, the length of the long side of the conveyed object H is longer than the interval between the inner surfaces of both frames 11 in the fifth conveyor 9, and the length of the shorter side is shorter than the interval between the inner surfaces of both frames 11. When the conveyed material H is sent linearly from the first conveyor 1 to the third conveyor 3, the first conveyor 1, the second conveyor 2, and the third conveyor 3 are connected in series as shown by a straight line in FIG. And then transport. In order to diverge the conveyed product H in the direction of the fourth conveyor 8, the second conveyor 2 is rotated clockwise, and the second conveyor 4 and the fourth conveyor 8 are conveyed in series. The conveyed article H moves from the first conveyor 1 to the second conveyor 2 and further rides on the fourth conveyor 8. Next, it moves from the group of drive rollers 10 to the fifth conveyor 9 and is sent out to the sixth conveyor 13.

Meanwhile, the conveyed object H rides on the first conveyor 1 in various postures. If the conveyed object H rides on the first conveyor 1 in a horizontally elongated state as shown by Ha in FIG. 1, the second conveyor 2, the fourth conveyor 8, the group of drive rollers 10, the fifth conveyor 9, and the The same attitude is maintained while being transported by the six conveyors 13. However, when the conveyed object H rides on the first conveyor 1 in such a posture as indicated by Hb, Hc, and Hd, the second conveyor 4 to the fourth conveyor 8 maintain such various postures. And to a fifth conveyor 9 via a group of drive rollers 10. At this time, the transport speed of the group of driving rollers 10 is faster than the transport speed of the fifth conveyor 9 and the discharge end of the group of driving rollers 10 is located higher than the frames 11 on both sides of the fifth conveyor 9. The objects Hb, Hc, and Hd are vigorously thrown from the group of drive rollers 10 onto the fifth conveyor 9. As shown in FIGS. 5 (a) and 5 (b), the conveyed objects Hb and Hc input in an inclined state instantaneously rotate the center of gravity G because the corners hit the frame 11 and a reaction force is generated in the direction of the arrow. It rotates as a center and assumes a portrait orientation on the fifth conveyor 9. Further, as shown in FIG. 5C, when the transported object Hd rides on the fifth conveyor 9 in a horizontally long state, one end of the transported object Hd is dragged by the fifth conveyor 9 in the arrow direction. This corrects the posture in the vertical direction. Then, the conveyed articles Ha, Hb, Hc, and Hd in the vertically long state ride on the sixth conveyor 13 and are discharged.
