Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an article conveying apparatus having a storage function.
[0002]
[Prior art]
There is an apparatus (buffer device) that can carry out articles carried at irregular intervals from the previous process to the subsequent process at regular intervals (see, for example, Patent Document 1). In this buffer device, a plurality of article storage sections are formed in a loop-shaped chain that can move on a substantially oblong outer peripheral track, and the article storage section is set at a carry-in position set in one linear moving portion of the loop-shaped chain. The article housed in the container is transported to the unloading position set in the other linear moving section by rotating the loop-shaped chain and turning the article housing section. The buffer device is configured to slide the loop-shaped chain itself with two motors. By independently rotating and stopping these two motors, the buffer device accommodates articles at the carry-in position and the carry-out position. The compartments can be stopped independently in terms of timing so that articles can be carried in from the previous process and carried out to the subsequent process.
[0003]
In the buffer device, the loop-shaped chain slides to change the path from the carry-in position to the carry-out position (the chain length from the carry-in position to the carry-out position), and is stored in the article storage section between the two positions. It is possible to change the number of articles. That is, when the post-process is temporarily stopped for some reason and it becomes impossible to carry out the article from the article storage section that has reached the carry-out position, the loop chain is connected to the side where the path extends (the article storage side). ) To store the article, it is possible to continue to carry in the article from the previous process. In addition, when the time interval between the articles sent from the previous process becomes large, the looped chain is slid in the opposite direction and the stored articles are continuously carried out to the subsequent process at equal intervals. Composed.

[Problems to be solved by the invention]
When the processing capacity of the line including the buffer device and the preceding and following processes (the number of processes per unit time) is large, when the subsequent process is stopped, the apparatus is immediately filled with stored articles, and the previous process must be stopped. It becomes a situation that does not become. Similarly, when the pre-process is stopped, the article stored in the apparatus is immediately carried out and becomes empty, and the post-process must be stopped. That is, the buffer device cannot cope with a large processing capacity, and there is a possibility that the frequency of stopping the pre-process and the post-process is frequently generated.
[0006]
Although it is possible to reduce the frequency of stopping the pre-process and post-process by increasing the amount of stored articles by increasing the slide amount of the loop-shaped chain, in this case, the apparatus itself becomes longer. Cause a problem that requires a large installation space.
[0007]

In the carry-in mechanism B, the first carry-in carriers 14 and 14 at the forefront in the movement direction in the first carry-in article receiving groups 32 and 32 receive the article 12 at the receiving position R. ₁ (See FIG. 4).
[0035]
The article 12 conveyed by the carry-in conveyor 10 is discharged from the article conveyance terminal portion toward the first carry-in carriers 14 and 14, and the article 12 is discharged on the bottom surface by the first carry-in carriers 14 and 14. Both sides in the width direction are supported. When it is detected by the detection means that the article 12 has been received by the first carry-in carriers 14, 14, the first endless chains 23, 23 are moved by the first carry-in motor 30 to the first carry-in carrier 14. It rises intermittently at a pitch of the arrangement interval. When the above operation is repeated and 15 articles 12 are received in the first carrying-in article receiving groups 32, 32, the second in the moving direction frontmost part in the second carrying-in article receiving groups 33, 33 arranged subsequently. Carrying-in carrier 15, 15 receives position R ₁ The second endless chains 27 and 27 are rotated by the carry-in second motor 31 so as to arrive at. Then, every time the article 12 is continuously received by the second carry-in carriers 15 and 15, the carry-in carriers 15 and 15 are intermittently raised at a pitch corresponding to the arrangement interval, whereby the articles 12 from the carry-in conveyor 10. Will be accepted without interruption.
[0036]
When fifteen articles 12 are received in the first carrying-in article receiving groups 32, 32, the first endless chains 23, 23 are rotated at a predetermined speed by the first carrying-in motor 30, and the first carrying-in article receiver is received. The groups 32 and 32 are the delivery position T of the article 12 ₁ Ascend to stop positioning. Next, the carry-in pusher 35 is moved forward from the standby position toward the operating position, and the pusher 35 is moved to the delivery position T. ₁ In the process of passing through the gap formed between the first carry-in carriers 14, 14, 15 articles 12 are sent out at a time and positioned at the carry-in position I of the storage mechanism C and stopped. Are carried into the article container 48 at a time.
[0037]
When the article 12 is carried into the article container 48 at the carry-in position I, the motor 42 on the carry-in position I side is controlled to rotate by a predetermined amount, the driven endless chain 49 is rotated, and the article container 48 is arranged. The empty article container 48 is moved corresponding to the carry-in position I after being moved by an interval (one pitch). In this way, each time a predetermined number of articles 12 are carried into the article container 48 from the carry-in mechanism B, the operation of moving the driven endless chain 49 by one pitch is repeated, so that the storage mechanism C has A plurality of articles 12 are stored in each of the plurality of article containers 48.

When the article storage body 48 is moved to the front side in the moving direction and the next article storage body 48 storing the article 12 is stopped at the carry-out position O, the article 12 can be carried out. At this time, the position of the article container 48 facing the carry-in position I does not change. Further, when the article 12 is carried in during the carrying-out operation of the article 12, the motor 42 on the carry-in position I side is independently controlled to rotate in the normal rotation direction, and the movable body 38 accommodates the article at the carry-in position I. By moving the body 48 forward in the moving direction and stopping the empty article container 48 at the carry-in position I, the article 12 can be carried in. At this time, the position of the article container 48 facing the unloading position O does not change. That is, by independently controlling the rotation of the two storage motors 42 and 42, the movement and stop of the article container 48 so as to correspond to the carry-in position I and the carry-out position O are supported. The operation of moving and stopping is performed independently. For example, when the supply conveyor 13 (packaging machine) is temporarily stopped, only the motor 42 on the carry-in position I side is controlled to rotate, and the moving body 38 moves as described above, and the article is stored in the storage mechanism C. The storage amount of 12 increases. Further, when the article 12 conveyed by the carry-in conveyor 10 is interrupted, only the motor 42 on the carry-out position O side is rotationally controlled, and the moving body 38 is moved and stored as described above. The article 12 is unloaded from the storage mechanism C.
