Description

[Detailed description of the invention] Industrial application field The present invention is for individually sending out articles stored in multiple stages and rows, and by individually sending out a large number of articles transported at once to a production line etc. It is very useful as a means for automatically supplying goods in automated and unmanned factories.

BACKGROUND TECHNOLOGY When a large number of articles brought in in a container or the like are to be sent individually to a desired conveyance line, it has been conventional to first manually load the large number of articles onto a conveyor or the like and send them out individually. However, 1
The manual process of picking out individual items requires a great deal of effort and time, and as a result, the current situation is that the waiting time for a large number of items that are subsequently brought in is becoming longer.

Problems to be Solved by the Invention The present invention simultaneously unloads a large number of articles stored in multiple rows in a container into each tier, and arranges the multiple rows of articles that were unloaded at the same time. The aim is to automatically carry out the task of taking out individual items.

Means for Solving the Problems: A lifter that moves up and down a container in which multiple items are placed in multiple rows on each shelf of a multi-tiered shelf according to the pitch of each tier, and a lifter that is fixedly attached to one side of the container and that a multi-row extrusion pusher for pushing out multiple rows of articles to the other side of the container; an article delivery conveyor fixedly installed on the other side of the container in correspondence with the pusher; and a rapid feed conveyor connected to the terminal end of the delivery conveyor. an individual feed-out pusher that pushes out articles to be carried out laterally at the terminal end of the rapid-feeding conveyor; and a conveyor that is close to the conveyance surface of the carry-out conveyor and aligns the articles to be carried out. be.

Function: When a trolley with a frame that supports only the bottom edge of a container with multiple items placed in multiple rows on each shelf of a multi-tiered shelf reaches and stops directly above the lifter, it is fixed to one side of the top shelf of the container. The provided multi-row pusher is extended and operated to gradually push the multi-row articles to the other side of the container.

A carry-out conveyor is disposed on the other side of the top shelf position of the container in correspondence with the pusher, and the multi-row articles pushed out of the shelf by the multi-row pusher are transferred to the carry-out conveyor during operation. They are sequentially transferred onto a conveyor and carried out.

The alignment conveyor, which is disposed close to the conveying surface of the unloading conveyor, adjusts the width of the conveying surface of the unloading conveyor in accordance with the widthwise size of the articles to be conveyed by increasing or decreasing the turning angle, and thereby Since the width of the conveying surface is restricted to a width that only allows for the passage of articles, and the conveyance article passage restriction surface of the alignment conveyor forms an inclined surface that moves in the direction opposite to the conveyance direction of the discharge conveyor, irregularities may occur on the discharge conveyor. Among the articles lined up in the conveyor belt, the articles that collide with the passage restriction surface of the alignment conveyor stagnate at that position while convection occurs, and only the articles that do not collide are conveyed downstream in a single line and are placed on the fast-forwarding conveyor. Then, the distance between the next article and the next article is widened and the article reaches the end, and is carried out laterally by a delivery pusher and supplied to a desired processing means.

Furthermore, as the number of convectively stagnant articles increases, the articles pushed out from the shelf push the articles to a position where they do not collide with the regulating surface of the alignment conveyor, pass through, and are carried downstream.

When the multi-row pusher completes pushing out the multi-row articles on the top shelf, the pusher moves back and the lifter moves up one pitch to bring the next shelf directly facing the pusher, similar to the case on the top shelf. By the operation, the multi-row items on the next shelf are sent out individually,
Thereafter, the articles on each shelf are individually sent out in the same manner.

When all the articles on each shelf of the container are pushed out, the empty container cart is carried out, the next cart arrives, and the same operation is repeated for the next container.

Example Fig. 1 is a front view, Fig. 2 is a plan view, Fig. 3 is a side view, Fig. 4 is a plan view of the alignment conveyor, and Fig. 5 is a front view of the alignment conveyor, in which articles A are Container 1 having multi-tiered shelves stored in multiple rows on the shelves,
1' is carried onto the lifter 3 by the cart 2.

Since only the periphery of the bottom of the container 1 is supported by the frame of the cart 2, the lifter 3
The lifting plate 3' directly faces the bottom of the container 1.

Since the multi-row pusher 4 fixedly installed on one side of the container 1 directly faces the side surface of the top shelf of the container 1, the extension of the pusher 4 by the cylinder causes the multi-row pusher 4 on the top shelf to The rows of articles A are gradually pushed out to the other side, and as shown in FIGS.
It is transferred onto a carry-out conveyor 5 disposed opposite to the conveyor 5, and carried out in the downstream direction by the operation of the conveyor 5. In addition, in order to prevent the pushed out multi-row articles A from overflowing the conveyor 5 and falling outside the conveyor 5, the extension operation of the pusher 4 is performed by placing the multi-row articles A in the vicinity of the outer edge of the conveyor 5. Detectors S ₁ and S ₂ for detecting the amount of extrusion are arranged, and when the extrusion front of the multi-row article touches the detectors, the extension operation of the pusher 4 is stopped, and when it no longer touches the detectors, the extension operation starts again. is started.

The alignment conveyor 6 disposed close to the conveyance surface of the discharge conveyor 5 is shown in detail in FIGS. 4 and 5.

That is, a driving pulley vertical shaft 10 and a driven pulley vertical shaft 11 are rotatably supported on a support frame 9 which is horizontally rotatably attached to a horizontal beam member 7 fixed to a column erected on the floor with a vertical shaft 8. In addition, a drive motor M for a drive pulley vertical shaft 10 is provided, and an alignment conveyor 6 is endlessly wound around both pulleys.

Further, the horizontal beam member 7 is provided with a transmission mechanism 14 that connects the other end of an alignment conveyor rotation operating rod 13 screwed into a nut 12 whose one end is horizontally rotatably attached to the support frame 9, The transmission mechanism 14 is driven via a belt 16 by a rotary handle 15 attached to the column.

Therefore, when the handle 15 is rotated, the rotary operating rod 13 is rotated and the nut 12 is moved, so that the alignment conveyor 6 is horizontally rotated about the vertical axis 8.

In addition, the rotation handle 15 of the alignment conveyor 6
The amount of horizontal rotation is determined by the amount of horizontal rotation of the wire 1, which is tied to the support frame 9 at one end and suspended by attaching a vertical weight W to the other end.
A pointer 18 is attached to the hanging portion of the pointer 7, and a pointer scale 19 is attached to the pillar, and the indicated value of the scale 19 as the pointer 18 moves is detected.

As understood from FIG. 4, the alignment conveyor 6 is rotated on the discharge conveyor 5 by operating the rotary handle 15 to reduce or regulate the width of the conveyance surface of the conveyor 5. As the amount of horizontal rotation of the alignment conveyor 6 increases, the width of the articles carried downstream becomes smaller.

Therefore, if the conveyance surface width is regulated to be smaller than the total width of the two articles pushed out by the pusher 4, the articles are conveyed downstream in a line.

The remaining articles that cannot be arranged in a line collide with the backward movement surface of the alignment conveyor 6 and are prevented from moving downstream, since the alignment conveyor 6 is driven to run in a direction opposite to the carry-out conveyor 5. They are stored by convection while waiting until they are lined up in a line.

The articles A arranged in a line and carried downstream are widened by the fast-forwarding conveyor 20 to widen the distance between them and the succeeding articles, and are pushed out laterally by the individual feed-out pusher 21 at the end of the fast-forwarding conveyor 20. and supplied to the desired processing means.

When all the multi-row articles on the top shelf are pushed out by the multi-row pusher 4, the pusher 4 retreats, the lifter 3 operates to raise the shelf one pitch, and the next shelf directly faces the pusher 4, as described above. Repeating the same operation, the multi-row items on the bottom shelf are pushed out, container 1 becomes empty, and the next container 1'
moves forward to the position of lifter 3 and repeats the same operation.

In this way, a large number of prepared articles can be taken individually and fed in succession to the desired processing means.

Effects of the invention The present invention allows a large number of articles stored in a container and prepared to be taken out by mechanical means without manual labor, and the taken out items are detected by an article pushout amount detection device placed near the outer edge of the delivery conveyor. When pressed, the extrusion operation of the extrusion pusher is stopped, and the amount of articles extruded onto the carry-out conveyor is controlled so as not to overflow, so there is no fear that the extruded articles will fall from the carry-out conveyor.
Moreover, since the alignment conveyor is wound endlessly between the vertical axis of the driving pulley and the vertical axis of the driven pulley, all the articles pushed onto the carrying out conveyor are stored by convection and carried out individually. By unmanning and automating the supply of goods in the processing process,
It greatly contributes to the realization of labor saving and factory automation, and its effects are enormous.
