JPS5997918A - Synchronous control method of conveyed goods and conveyer to which goods are transferred - Google Patents

Abstract

PURPOSE:To improve the synchronism and transfer goods smoothly by detecting the conveyed goods just before they are transferred on a conveyer to find out if they are within a synchronous transferring lot and constructing to control the speed of conveyed goods to be within a synchronous range. CONSTITUTION:Advancing goods held between a vertical belt A are detected by a photoelectric switch PH1. At this stage, a time range M-N for the conveyer 2 to transfer goods synchronously is previously set to judge whether they are within a synchronous range. That is, when the goods pass within the range M-N, they can be conveyed as they are, but when they are out of the range M-N and pass Q, for instance, the speed is controlled from Q to R as a solid line (B) shows. The synchronism of the goods transferred to the conveyer 2 is checked and ensured by a photoelectric switch PH2. This construction permits to improve the synchronism and transfer goods smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for synchronizing randomly flowing conveyed articles and a conveyor on which they are transferred.

For example, when transferring the conveyed articles loaded on conveyor Ill and flowing randomly to a packet on another conveyor (2) provided in front of the conveyor II+, to place the articles one by one on the packet. In order to ensure that the conveyed articles and the conveyor (packets) move synchronously.

The present invention is extremely convenient for use in such cases by detecting the position of the article in front of the conveyor where the article is being conveyed, and detecting the article within the range where the article moves in synchronization with the conveyor in front. When K continues to be transported,
On the other hand, when it deviates from the four tracks, the multi-travel speed of the conveyed article is controlled so that it is within the range of synchronization with the conveyor. explain.

After the conveyor ill running at a predetermined speed, left and right 1
A pair of vertical belts (5) and β) are installed, a photoelectric switch (PHZ) is installed on the side of the conveyance path immediately in front of the vertical belt (5) on the hand 111 side, and another photoelectric switch (PHZ) is installed on the side of the vertical belt (). A switch (PH,) is provided.

In front of the conveyor pile is a conveyor (2) on which packets or attachments are mounted at regular intervals. When the articles sent by the conveyor urrm and the conveyor (2) move in synchronization, the articles can be placed one by one in a packet.

For example, the front vertical belt (8) is made to run at a speed of 2 of the front vertical belt Ill, and
Vertical Calpel) CB+ l-j It is assumed that the transport device runs slightly faster than the operating speed of the machine (for example, the coloring device for this article) that includes this conveyance device.

Under this condition, the articles sent from the conveyor Ill are held by a pair of left and right vertical belts (8) and move further forward, blocking the light when passing the photoelectric switch (PHI). A time range in which the conveyed articles and the conveyor (2) can move synchronously at this position is set in advance. For example, assume that the range is within lli LJ of point M-N shown on the horizontal axis of the drawing. Note that this range can be determined by the position at which the conveyed article is transferred to the packet on the conveyor (2).

Therefore, when the conveyed article moves along the path shown by the solid line A in the drawing, the solid line A passes through the entire range of M-N as shown in the drawing. At the detection position, the conveyed article and the conveyor (2
) can be confirmed to be migrating in sync. In this case, the conveyance is continued as is. When the article reaches the vertical belt (G)), it is transported by the vertical belt [F]) at twice the previous speed, and then the conveyor (2), which is running in synchronization with the article, is transported by the vertical belt [F]). sent to.

In this case, the solid line A should cover the time range S-T that blocks the light of the photoelectric switch (PHI), and at the position of the photoelectric switch (PH1), the transported goods and the conveyor (
2) is again confirmed to be transitioning in synchronization with a1.

If the S-T range is exceeded, it is preferable to turn on a defective indicator lamp and stop the machine.

Next, when the conveyed article traces the trajectory indicated by the solid line, L! I
For example, when the transported article deviates from the range of M-N and blocks the light from the light switch (PH M-
The vertical belt (5) is decelerated to the initial speed A (2 speed of the vertical belt (B)) through the intermediate point Q of H to the point R where PQ=QR, and when it reaches point R, the Stop the control and resume driving at the original speed.

In this way, the article sent out of the synchronization range M-N will be decelerated once until its transfer speed is synchronized with the conveyor (2), and then adjusted once to synchronize with the conveyor (2). Then, it is transferred again at the original speed. Therefore, the articles that could not originally be transferred to the packets on the conveyor (2) are reliably stored in the bucket (K) by the above-mentioned control.

In addition, in the figure, the range within the dotted line indicates the range in which the conveyed article and the conveyor on which it is transferred are synchronized, and within this range, V
When the CC edge line is drawn, the first reapers are moving synchronously.

In the above embodiment, the vertical belt (3) is decelerated in order to synchronize the conveyed articles and the conveyor (2), but it is also possible to synchronize both by accelerating the vertical belt (8). You can also do this.

In addition, in the case of the above embodiment, the control time of the vertical belt (3) was set to twice the time from when the article blocked the light of the photoelectric switch (PH,) until it reached the midpoint of the synchronization range. This is to ensure that the above control is performed without malfunction. However, the setting suite is not limited to this case.

In addition, as a linkage control mechanism of the vertical belt (8),
This can be done using a conventionally known differential gear arrangement and clutch mechanism.

The present invention has the advantage that synchronized control of the conveyed articles and the conveyor 2 on which they are transferred can be easily and easily performed.
