With this, buckets (a) and (c) which are before and after an intermediate bucket (b) are kept at postures bending forward and rearward respectively when the intermediate bucket (b) is apt to shift to the posture bending forward from the posture bending rearward, and a overlapping state of the flanges 4 and 5 is reversed between the buckets (a) and (c) which are before and after the bucket (b).

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bilateral packet conveyor.

In this conveyor, flanges are usually provided at both (or one) of the adjacent ends of adjacent packets so that the conveyed material can be continuously thrown into each packet by the horizontal packet moving section. ) are overlapped in the horizontal movement part of the butterfly, and in order to move the packet horizontally - descending or rising,
A wrap change is required to turn the overlapping state of the flanges upside down. However, in the past, wrap change was only performed in the horizontal packet moving section by utilizing the packet movement when discharging the transferred material, and it was said that it could not be done for its own purpose; The wrap change is performed in the conveyor section that advances the packets, and the wrap change mechanism installed in the core part does not work at all against the backward movement of packets. The drawback was that the direction of travel was fixed.

The present invention was devised to solve the above-mentioned conventional problems, and is provided with a wrap change mechanism that can reliably and smoothly change wraps regardless of the packet traveling direction in the horizontal packet moving unit. The purpose of the present invention is to provide a pivoted packet conveyor that enables reverse transport.

The present invention will be explained below with reference to illustrative embodiments.

In the figure, reference numeral 1 designates a pair of endless drive chains that are rotatably driven by a plurality of tin rockets, and are interconnected by a common pivot 2. Reference numeral 3 denotes a packet pivotally supported on the shaft 2 of the chain 1, and flanges 4 and 5 are provided at both ends of the packet 30, and flanges 4 and 5 are provided at the lower portions of both sides in opposite directions of swing. One guide row 26, 7 is provided with a shifted position. 8,9
are first and second guide rails arranged in parallel in the packet horizontal movement section of such a conveyor, and the guide rail 8 has a guide with an upward slope that can be held by the guide roller 6 on the front side in the packet traveling direction. A surface 10 is provided, and a guide rod
- The wheel 9 is provided with a downwardly sloped guide surface 11 that can be held by the guide roller 7 on the rear side in the packet traveling direction. The guide rails 8 and 9 are provided in this order in the packet traveling direction so that the rail ends overlap each other in a direction perpendicular to the core direction.

Since the present invention is based on the above, when the chain 1 is driven, the packet 3 that has descended around the tin rocket is placed on the 7th direction 5 on the rear side in the packet traveling direction. The flanges 4 on the front side in the packet traveling direction of the packets 3 overlap each other, and each packet 3 moves horizontally to the position of the guide rail 8.9 in the straight state. Next, the guide roller 6 on the front side in the packet traveling direction first engages with the guide surface lO of the guide 1/-rail 8 and is lifted as the packet moves forward, but the guide roller 7 on the rear side in the packet traveling direction is still not engaged with the guide rail 9. Chain 1
The packet 3 pivoted on the chain 1 loses its front-to-back balance and is tilted rearward about the common axis 2 of the chain 1. Next, when the guide row 26 on the front side in the packet traveling direction comes off the guide surface 10 of the guide rail 8 and is about to fall onto the end surface 12, the guide row 27 on the rear side in the packet traveling direction
is located on the end surface 13 of the guide rail 9, so even if the front guide roller 6 in the packet traveling direction comes off the guide surface 10 of the guide rail 8, the rear guide roller 7 in the packet traveling direction will not touch the end surface 13 of the guide rail 9. As the packet 3 is caught and advances, the packet 3 is gradually tilted forward about the common axis 2 of the chain 1 in the opposite manner to the above. Then, from around the point where the rear guide row 27 in the backward traveling direction is pulled up to the guide surface IJ, 1: of the guide rail 9, the packet 3 gradually weakens its forward leaning posture, and the guide rail 9
When it comes off, recover the original posture.

If we look at the following Bakut motion for the three adjacent packets 3, the middle b packet 3 is the backward-leaning packet 3.
are maintained in the forward and backward tilted postures, respectively, so that a lap change between the a and C packets 3 that reverses the vertical configuration of the 7 lunges 4 and 5 is performed reliably and smoothly.

If the packet traveling direction is reversed, the front and rear guide rails in the packet traveling direction will simply become guide rails 9 and 8, respectively, contrary to the above case, and the wrap change mechanism is the same, so the conveyor can be reversed. The above-mentioned lap change effect can be ensured even when the train is operated.

Note that the guide provided at the lower side of the packet 3 can be rotated with respect to the packet body by guide rollers 8 and 9, but it may also be fixed integrally with the packet body, such as in a nine-way configuration.

Therefore, according to the present invention, regardless of the packet traveling direction,
Wrap change in the horizontal packet movement section can be performed reliably and smoothly with a simple mechanism, and it can also be easily applied to existing equipment, providing a comprehensive effect.
