Abstract

PURPOSE:To surely send down board like bodies in a stock portion by providing a cylinder which separates a weight vehicle from the board like body while pressing the board like body, on the weight vehicle. CONSTITUTION:As a selector valve 10 is switched over from a pipe 8 to a pipe 9, an adsorbing pad 6a is projected out via a first cylinder 6b and brought into contact with a partition 4 to start an adsorbing action. At this time, the air cylinder 7 of a weight vehicle 3c is synchronously driven with the first cylinder 6b projecting out a rod 7a to press the partitions 4, while the weight vehicle 3c is retracted from the partitions 4 in accordance with the projecting out of the rod 7a. As the selector valve 10 is continuously switched over, the connection to an air source 12 is switched over from the pipe 9 to the pipe 8. By this switchover, the adsorbing pad 6a is retraced via the first cylinder 6b while the rod 7a is synchronously retracted, both being separated from the partitions 4. At this moment, a distance is created between the weight vehicle 3c and the partition 4 and the weight vehicle 3c rolls at the distance by its own weight and collides with the partitions 4, to forcibly push in the partitions 4 from an upper course side to a lower course side.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a plate-like body supply device, and particularly to a plate-like body supply device suitable for supplying partitions to partition boxes into containers. Regarding equipment.

[Conventional technology]

A conventional plate-shaped body supplying apparatus will be explained by taking as an example a partitioned supplying apparatus for boxing shown in FIG. According to the figure, the bottles 1 to be packed in boxes flow down together with the line 2, and when they reach the partition supply device, they come to rest as the line 2 is stopped.

The partition supply device receives the stock section 3 adjacent to the side of the line 2 and the partition 4 stored in the stock section 3 as shown in FIG. (not shown).

On the inclined base 3a of the stock part 3, a large number of inner partitions 4 are stacked and placed against each other, and guides are provided at both ends and the upper end of the stacked inner partitions 4 to align and guide the inner partitions 4 downward. Members 3b are respectively provided. A weight wheel 3c is disposed on the upstream side of the inclined base 3a, and is configured to press the partition 4 downstream by the weight of the weight wheel 3C. Furthermore, a claw 3d for locking the partition 4 onto the base 3a is bent at the downstream end of the guide member 3b.

On the other hand, the delivery device 6 is disposed facing the downstream end of the stock section 3. The delivery device 6 includes a suction pad 6
It is provided with a first cylinder 6b that drives the cylinder a and a second cylinder 6C that raises and lowers the first cylinder 6b. Therefore, the second
When the first cylinder 6b is driven at the ascending end position of the cylinder 6c and the suction pad 6a advances into the stock section and contacts the partition 4 at the downstream end, a vacuum device (not shown) is driven to remove the inside of the suction pad 6a that has come into contact with it. The pressure is reduced and the suction is applied to the partition 4, and then the suction puff drawer a is moved by the first cylinder 6b.
When it is retracted, the partition 4 is bent against the claw 3d of the stock part 3 and pulled out, and the partition 4 that has reached the retracted end is positioned above the drop guide part. When the suction pad 6a reaches the retraction end, the second cylinder 6c
is driven to lower the suction pad 6a together with the first cylinder 6b and guide the partition 4 to be delivered to the gap formed in the drop guide section. When the partition 4 approaches the gap, the degree of vacuum of the suction pad 6a is returned to normal pressure, and the suction pad 6
A releases the partition 4 and drops it into the gap in the drop guide section.

A drop guide part 5 drops and inserts a partition 4 between two rows of bottles 1 along a line 2 through a gap, thereby dividing the bottles 1 into two rows. Thereafter, the stopped line 2 is activated to transport the bottles 1 to the next step of packaging.

[Problem to be solved by the invention]

As is clear from the above configuration, the conventional partition supply device has the following features:
The inner partition 4 is restrained fairly tightly by the guide part key 3b so that the alignment of the inner partition 4 within the stock part 3 is not disturbed. Therefore, if the inner partition 4 absorbs moisture and swells even slightly, it will be prevented from sliding inside the stock part 3, and the inner partition 4 will not be able to move smoothly into the stock part 3 with only the pressing action of the weight wheel 3b.
The supply of the inner partition 4 could be hindered because it could not be guided to the downstream side of the -\. Further, if paper dust is accumulated in the partition 4 without absorbing moisture, smooth supply of the partition 4 may be inhibited as described above. Furthermore, if the partition 4 itself is warped or the suction position of the suction pad 6a is misaligned, the supply of the partition 4 will be inhibited.

The present invention was made to solve the above problems, and
Plates such as partitions may absorb moisture and swell, or paper dust may accumulate, or the plates may warp, or the plates may be biased when the suction pad is suctioning. It is an object of the present invention to provide a plate-shaped object supplying device that allows the plate-shaped objects to flow down reliably in a stock section.

[a! Means to solve the problem]

In the present invention, a storage section for storing a plurality of plate-shaped bodies in a stacked arrangement is arranged in an inclined manner, and a weight wheel is rolled so as to press the plate-shaped bodies from above to below the stock part. The suction pad is freely arranged, advances through a cylinder to the lower end of the plate-shaped body pressed by the weight wheel, and adsorbs the plate-shaped body, and as it retreats, the plate-shaped body is taken up from the stock part, and the suction pad is supplied as needed. In the plate-shaped body supply device configured to be disposed opposite to the stock part, a cylinder is disposed on the weight wheel to press the plate-shaped body and separate the weight wheel from the plate-shaped body, The above object has been achieved by providing a plate-shaped body feeding device characterized in that the suction operation of the suction pad is synchronized with the pressing operation of the cylinder.

[Effect]

According to the present invention, when the suction pad advances and comes into contact with the plate-like body at the downstream end and adsorbs it, the cylinder of the weight truck is driven in synchronization with this movement, and presses the plate-like body at the upstream end. While sandwiching the overlappingly arranged plate-like bodies, the weight wheel retreats and separates from the plate-like bodies. Then, at the same time as the suction pad retreats, the cylinder of the weight truck retreats, so a gap is formed between the weight truck and the plate-like object, causing the weight car to roll under its own weight and collide with the plate-like object. to prevent clogging of the plate.

〔Example〕

Hereinafter, based on FIGS. 1 and 2, the same or equivalent parts as those in the prior art will be denoted by the same reference numerals, and the explanation thereof will be omitted, and the features of the present invention will be mainly explained.

As is clear from FIG. 1, in the partition supply device of this embodiment, an air cylinder 7 is attached to a weight wheel 3C disposed upstream of the stock section 3.

Air cylinder 7 is connected to switching valve 10 via line 8.9. The switching valve 10 is further connected to an air source 12 via a pipe 11, and is configured to supply compressed air to the air cylinder 7 via the switching valve 10 to move the rod 7a of the air cylinder 7 forward and backward. There is.

Further, the pipe 8.9 connected to the switching valve 10 is also connected to the first cylinder 6b which drives the suction pad 6a, and is driven in synchronization with the air cylinder 7 of the weight wheel 6C.

Therefore, when the switching valve 10 is in the state as shown in FIG.
The air source 12 communicates with the pipe 8, and the first cylinder 6b and air cylinder 7 connected to the pipe 8 have their respective rods retracted.

Then, when the switching valve 10 is switched from the pipe 8 to the pipe 9, the suction pad 6a advances through the first cylinder 6b, contacts the partition 4, and starts suction operation. At this time, the air cylinder 7 of the weight wheel 6C is driven in synchronization with the first cylinder 6b, advances the rod 7a and presses the partition 4, and the weight wheel 6C moves into the partition 4 in accordance with the advance of the loft 7a. retreat from. When the switching valve 10 is subsequently switched, the connection of the air source 12 is switched from the pipe 9 to the pipe 8. Due to this switching, the suction pad 6a retreats via the first cylinder 6b, and in synchronization with this, the rod 7a of the air cylinder also retreats and leaves the partition 4 together.

At that moment, a distance is created between the weight wheel 6C and the partition 4, and the weight wheel 6C rolls that distance due to its own weight and collides with the partition 4, moving the partition 4 from the upstream side to the downstream side. push in,
In other words, even if a part of the partition 4 is caught in the stock part 3 due to the impact force caused by this collision, it is released and the partition 4 can be supplied without any hindrance.

In addition, the air fQ12 is supplied to another switching valve 14 via piping 13.
It is connected to the. This switching valve 14 is further connected to the pipe 15.1.
6 to the second cylinder 6C, and is configured to supply compressed air from the air source 12 to the second cylinder 6C.

Thus, the first cylinder 6b is moved up and down by the switching operation of the switching valve 14 via the rod 6d of the second cylinder 6C, and the partition 4 adsorbed to the suction pad 6a is dropped into the drop guide section. .

Next, the operation of the partition supply device of this embodiment will be explained with reference to FIG.

+al in the same figure shows a state in which the supply of the partition 4 is expected,
In this state, the switching valve 10.14 is in the state shown in FIG. Next, when the switching valve 10 is switched from the state shown in FIG. 1 to connect the air source 12 to the pipe 9, the suction pad 6a is connected to the first cylinder 6b, and the rod 7a is connected to the air cylinder 7.
The suction pad 6a contacts the partition 4 at the downstream end, and the rod 7a pulls the weight wheel 6C away from the partition 4 while pressing the partition 4 at the upstream end. ) Proceed to the adsorption process in the state shown. For suction, use suction pad 6
This is done by a vacuum device (not shown) that works in conjunction with the contact of a to the partition 4.

Subsequently, when the switching valve 10 is switched to the state shown in FIG. 1, the air source 12 is communicated with the pipe 8, the suction pad 6a and the rod 7a are both moved backward, and the suction pad 6a transfers the partition 4 above the drop guide section. do. On the other hand, the rod 7a of the air cylinder 7 is instantly separated from the partition 4 and placed in a second position between the weight wheel 6C and the partition 4 at a distance commensurate with the size of the rod 7a.
The state shown in Figure (C) is reached.

The moment there is a distance between the weight car 6C and the partition 4, the weight car 6
c rolls downward due to its own weight, and is placed in the partition 4 as shown in Fig. 2 (
It operates so as not to collide as shown in d+ and cause a catch inside the stock part 3.

Meanwhile, while the weight truck 6C collides with the partition 4 as shown in FIG. 2 (d+), the other switching valve 14 switches and the air source 1
2 to the piping 15 to connect the rod 6 of the second cylinder 6C.
d, the first cylinder 6b, that is, the suction pad 6a, is lowered and the partition 4 is inserted into the drop guide section. At this time, the vacuum level of the suction band 6a is released, the partition 4 is dropped, and the switching valve 14 is lowered again. Switch to piping 16 and attach suction pad 6
A is returned to the standby state (FIG. 2 (state of al)), and the series of operations is completed.

Note that the present invention is not limited to a supply device for partitions, but can be widely applied to devices for supplying plate-shaped bodies such as the partition 4.

(Effects of the Invention) The plate-shaped body feeding device of the present invention prevents the plate-shaped bodies such as partitions from absorbing moisture and swelling, or paper dust may accumulate, or the plate-shaped bodies may warp. Even if the plate-like body is biased during suction by the suction pad, the plate-like body within the stock part is reliably flowed down.
