Description

[Detailed description of the invention] (Field of industrial application) This filial idea moves articles by their own weight to the front of the shelf, and uses a cutting device installed at the front exit to load the articles stocked on the shelf one by one. This invention relates to a so-called flow rack device that can be taken out.

(Prior Art) The above-mentioned flow rack device has an excellent advantage of having a simple structure and requiring no special power for moving articles. When the length and capacity are increased, the following problems occur.

(Problem to be solved by the invention) In other words, the pressure applied to the front surface of the cutting device becomes excessive due to the large pressure in the downward movement direction of a large amount of articles, making it impossible to reliably cut out the objects, or causing the drive device of the cutting device to stop working. Even if the reliability of cutting is increased by using a high-power tool, there is a risk that the product itself will be damaged due to the large impact caused by the cutting.

Therefore, the object of this invention is to provide a flow rack device which does not suffer from the above-mentioned drawbacks even when the length and capacity increases, and which still has the above-mentioned advantages inherent to the flow rack.

(Means for Solving the Problems) In order to solve the above object, the flow rack device according to the present invention is provided with an article cutting device and a brake device interlocked with this cutting device on the exit side of the flow rack device, A stopper for the article is provided in the side flow rack portion, and the cutout device is provided so as to be movable up and down between the article conveying surface of the flowrack and the upper end surface of the stopper, and the cutout device and the brake device are connected to the lift of the cutout device. This system is designed to allow the movement of articles as they descend, and to prevent them from moving as they descend. .

(Function) In the flow rack device having the above structure, when the cutting device for taking out the article rises, the operation of the brake device is released, and the subsequent article comes into contact with the rear end of the cutting device and stops. When the unloading of the articles is completed and the cutting device begins to descend, the brake device acts to prevent the articles from moving, and the articles on the flow rack are stored in a row ahead of the brake device and a row behind the brake device. Simultaneously with the completion of the lowering of the cutting device, only the front row portion moves forward until it comes into contact with the stopper on the exit end side.

(Example) Examples will be described below based on the drawings.

FIG. 1 is a side view of a flow rack device 1 according to the invention with a crane 2 for replenishing articles attached to the entrance side. When the amount of articles stocked on each shelf 3 of the flow rack device 1 decreases, the crane 2 A lift table 4 with a roller conveyor moves to the height of the shelf 3 to supply and replenish the articles 5.
The replenished articles 5 move downward by their own weight on the rollers 6 of each shelf 3 along the slope of the shelf, and are cut out one by one by a cutting device 7 provided at the exit end, and are placed on the side of the shelf. Although it is designed to be carried out onto a roller conveyor 8 running in a direction perpendicular to the stage 3,
In front of the cutting device 7, a brake device 9 and an article starting device 11 are provided to smoothly cut out the article and move the article.

The cutting device 7, the brake device 9, and the article starting device 11 will be described in detail below.

That is, in FIGS. 2 to 5, reference numeral 12 denotes a support frame for the cutting device 7 fixed to the outlet end of each shelf 3, and two front and rear rotation shafts 13 and 14 supported by the support frame 12 are connected to the support frame 12, respectively. Crank plates 15 and 16 are fixed, and an elevating roller block 17 for cutting out is supported by a shaft 18 at one end of the crank plates 15 and 16. The other end of the crank plate 15 on the left side in FIG. 4 of the front rotation shaft 13 is fixed to the support frame 12 19.
The rod 21a end of the fluid cylinder 21 is connected to each other, and the crank plates 15 and 16 on the right side of FIG.
1 expands and contracts, the lifting roller block 17 moves to the shelf 3.
In other words, the height of the roller 6 is raised and lowered between the solid line and the chain line in FIG.

The lifting roller block 17 consists of a frame body 23, a roller 24 provided on its side, and a length adjustment bolt 25 threaded onto the end face. By adjusting the threaded length of the bolt 25, the lifting roller block 17 can be adjusted. The actual front-to-back length can be increased or decreased, and the cutting operation can be performed smoothly even if the front-to-back width of the article changes as the article to be handled changes.

In addition, if the length of the article increases or decreases to an extent that cannot be accommodated by the length adjustment bolts 25, the entire frame 23 of the roller block can be replaced with another frame of a different length. It's getting old.

The cutting device 7 is configured as described above, and if the lifting roller block 17 rises from the lowered state,
The article 5 is placed on the elevating roller block 17, lifted up, and moved forward on the rollers 24 in the direction of the roller conveyor 8. A lever 26 with a roller is further fixed and protrudes from the rotating shaft 13. When the rotation shaft 13 rotates in the upward direction of the lifting roller block 17 and the lever 26 rotates upward,
One end 28a of the tiltable roller device 28 (FIG. 3) provided between the rollers 27 of the roller conveyor 8
is lifted as shown in the second figure, and the article 5f is moved on the roller device 28 and smoothly transferred onto the roller conveyor 8. 28b is a pivot point on the other end side of the roller device 28, and 29 is a large number of rollers arranged in rows.

Next, the brake device 9 will be explained. The brake device 9 has a structure substantially similar to that of the cutting device 7, and has two rotation shafts 32, front and rear, supported by a support frame 31 fixed to the shelf 3. 33 and crank plates 34, 3 fixed to the rotation shafts 32, 33, respectively.
5, and a shaft support 36 at one end of the crank plates 34, 35.
A connecting rod 38 connects the brake shoe block 37 and the front and rear crank plates 34, 35.
When the rotating shafts 32 and 33 rotate and the brake shoe block 37 rises above the roller 6, the brake shoe 39 of the block 37
The article 5 is braked when it rides on top of the article 5, but the rotation of the rotation shafts 32 and 33 is caused by the rotation of the rotation shaft 32.
A lever 41 fixedly protruding from the cutting device 7 and a lever 42 fixedly protruding from the rotating shaft 14 of the cutting device 7 are connected by a rod 43 to be driven.

And, each rotation shaft 3 of the levers 41 and 42
2 and 14, so that the elevating roller block 17 and the brake shoe block 37 move up and down relative to each other like a seesaw, that is, when one is going up, the other is going down, and the other is going down. When one is moving, the other is rising.

Further, the structure of the brake shoe 39 is formed in a chevron shape with a length approximately twice the front and rear width of the article with the front and rear slopes, but the brake shoe 39 is removable from the block 37. Goods 5
It can be replaced with various types depending on the size, material, weight, etc.

For example, in the case of a normal cubic-shaped article,
Urethane rubber is baked on the surface, and the length is about 500 to 700 mm, which has a slightly higher braking force, depending on the size of each item, but the front and rear width is smaller than the left stone width or height, causing it to fall. In the case of easy-to-use items, a brake shoe 39 that is made of iron plated with chrome plating and has a slightly lower braking force, and whose length is set slightly longer depending on the size of the item, is suitable. There is.

Next, a description will be given of the article starting devices 11, which are provided in large numbers upstream of the brake device 9.

That is, as shown in FIGS. 6 to 8, the shelf 3
Inclined plates 44 are provided at appropriate intervals along the longitudinal direction.
A long rectangular pipe 46 is provided on the inclined plate 44, which is rotatably supported through rollers 45 and is freely movable back and forth. As shown in FIG. 6, one end of the square pipe 46 is connected to a lever 47 which is fixed and protrudes from the rotating shaft 33 of the brake device 9.
and a connecting rod 48, and when the brake shaft block 37 moves downward, the square pipe 46 rides on the inclined plate 44 and moves forward diagonally upward (as shown by the solid line in Fig. 7). → chain line), but the square pipe 46
The following sliding contact plates 49 are provided at appropriate intervals.

That is, as shown in the seventh and eighth figures, the square pipe 4
A bracket 51 is attached to the bottom surface of the lever 6, and a lever 53 is provided with one end of the lever 53 being pivotally supported 52, and a sliding contact plate 49 having a cross section as shown in FIG. A torsion spring (not shown) is interposed on the support shaft 52 of the lever 53, and the sliding plate 49 is always biased in the upward direction (in the direction of arrow A in FIG. 7). 55 is a stopper pin that restricts the end of rotation of the lever 53 in the direction of arrow A.

Since the sliding contact plate 49 is configured as described above, when the square pipe 46 rides on the inclined plate 44 and moves forward diagonally upward, the upper surface of the sliding contact plate 49 will touch the article placed on the roller 6 of the shelf board. 5, and then, while in this contact state, press the square pipe 4.
6 is absorbed by the rotation of the lever 53 in the direction opposite to the arrow A, that is, the amount of upward movement of the lever 53 is absorbed by the rotation of the lever 53 against the torsion spring. With the contact pressure increased, the sliding contact plate 49 moves forward while rubbing against the bottom surface 5a of the article.

Note that in cases where the horsepower of the fluid cylinder 21 can be increased, when the shelf 3 is not so long, or when the weight of the article is light, the sliding contact plate 49 is not provided and It is also possible to directly lift the article 5 and move it forward using the square pipe 46 that moves forward. In that case, if the inclined plate 44 is made to have a gentle slope, the cylinder 21 with a smaller horsepower is sufficient.

The flow rack device 1 of this embodiment has the above structure, and a large number of articles 5 are placed on the rollers 6 of the shelves 3 by the crane 2.
are sequentially lowered and cut out in the following manner.

That is, in a normal state, the cylinder 21 of the cutting device 7 is contracted, the lifting roller block 17 is in the lowered position, the brake shoe block 37 is in the raised position, and the sliding plate 49 of the starting device 11 is in the lowered position.
is in the lowered position, and the article 5 on the roller 6 is stopped by the stopper plate 56 at the exit end, and at the same time is braked at the brake device 9 position, so that the article 5 on the roller 6 is substantially The articles are stored separately in a row section A in front of the brake device 9 and a row section B behind the brake device 9 (FIGS. 1 and 6). In this state, new articles 5 are introduced from the entrance side.

Therefore, even if the impact caused by the introduction of a new article 5 is transmitted to the article 5e in the front row of the rear row section B, the article 5e is stopped by the frictional force on the brake shoe 39. Therefore, if the article 5 is pinched between the stopper plate 56 or the like and subjected to deformation pressure, it will not cause damage, and no large impact will be transmitted to any article 5 on the shelf 3.

Then, when the cylinder 21 is extended from this state and the lifting roller block 17 is raised to the state shown in the second figure, the article 5f in the front row of the front row section A is placed on the lifting roller block 17 and lifted. , are cut out and carried out onto the roller conveyor 8 via the roller device 28 as described above, but at this time, the frontmost article 5f is only subjected to pressure equal to at most several articles in the front row section A. I haven't hung up yet,
Even if the fluid cylinder 21 has a small horsepower, the front article 5f can be lifted and cut out very smoothly and quickly.

Furthermore, by raising the elevating roller block 17, the shoe 39 of the interlocked brake device 9 is lowered to release the brake, and at the same time or just before the front article 5f is lifted, the articles 5 in the rear row B are lowered. It is connected to the articles in the front row A, and at this point the articles on the shelves 3 form a substantially continuous row. In addition, at this time, that is, when the brake shoe block 37 descends, the sliding contact plate 49 of the starting device 11 rubs the lower surface 5a of the article forward while contacting with an appropriate pressure as described above, so that it can be moved for a long time. The articles 5, which were not moved and could no longer move smoothly due to the effects of dents that fit into the rollers 6 formed on the lower surface 5a of the articles, are also promoted to move downward, and the articles in the back row B are moved smoothly as a whole. do.

The articles 5, which have temporarily formed a substantially continuous line as described above, are then moved again by the lifting roller block 17 being lowered again and the brake shoe book 37 being raised. It is essentially divided into two rows A and B, front and rear.

That is, by raising the brake shoe block 37, the downward movement of the articles 5 behind the brake device 9 position is stopped, forming the rear row B, and the lifting roller block 17 is sunk below the rollers 6. As a result, several articles 5 between the cutting device 7 and the brake device 9 are moved forward by approximately one article until stopped by the stopper plate 56, forming a front row A. It will be done.

When the elevating roller block 17 descends, the roller device 28 descends and sinks onto the rollers 27 of the roller conveyor 8, so the article 5 that has moved downward on the roller device 28 is transferred onto the roller conveyor 8. , and thereafter carried out by the conveyor 8 in the orthogonal direction.

(Effect of the invention) As is clear from the above explanation, the flow rack device of this invention is provided with an article cutting device and an article braking device interlockingly connected to the cutting device, so that the article rows on the shelf can be substantially controlled. Since the cutting operation is performed in two rows divided into the front and back,
Even if the shelves become longer and the pressure applied to the rows of articles in the front and rear directions increases, the cutting operation can be performed reliably and smoothly, and a small drive source can be used as the driving source for the cutting device.

In other words, conventional flow racks (for example, Japanese Patent Application Laid-open No. 1983-1999
151505), the force of moving all the articles placed on the flow rack downstream is applied to the articles in the front row, so the frictional force when lifting the articles for removal is large and smooth. In contrast, according to the present invention, only the pressure of the number of articles existing between the braking device and the front row is applied to the articles in the front row, so it is possible to cut out articles quickly. .
