The present invention relates to an article supply device capable of supplying articles.

[Conventional technology]

For example, in the field of manufacturing sweet bread, the manufactured sweet bread (article) may be transported to a packaging device.

FIG. 9 shows an example of a conventional conveying device for conveying a cake called heavy cake, which is somewhat hard and easily sticky, toward a packaging device.

This conveyance device includes a top chain 11 that travels in the direction of arrow A at a constant speed. The top chain 11 is provided with partition pieces 12 at regular intervals.

When the heavy cake 13 is transported by this transport device, the heavy cake 1 sliced after baking is
The heavy cakes 13 are brought to the vicinity of this conveying device, and an operator feeds one heavy cake 13 between each partition piece 12 of the top chain 11. This supplied heavy cake 13 is
It is conveyed as it travels in the direction of arrow A, and is fed into a packaging device (not shown) and packaged. It is the heavy cake 13 that supplies one heavy cake 13 between each partition piece 12 of the top chain 11.
This is to synchronize the conveyance of the paper and the wrapping operation of the packaging device.

[Problem that the invention attempts to solve]

By the way, in such a conventional conveying device, the work of feeding the heavy cake 13 one by one between each partition piece 12 of the top chain 11 is carried out manually, which is extremely troublesome and also reduces the overall cost. There was a problem that became a major hindrance in trying to automate the process.

The present invention has been developed in view of the above circumstances, and provides an article feeding device that can separate and feed articles such as heavy cakes one by one between each partition piece of a conveying device consisting of a top chain or the like. The purpose is to

[Means for solving problems]

The first article is separated from the next article by a sprocket while being held down by the sprocket, and the article is then tipped forward by its own weight at the desired timing, and the articles are fed one by one between each partition piece of the conveying device. It was designed to do so.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to examples.

FIG. 1 shows the main parts of an article supply device in an embodiment of the present invention. In this figure, the same parts as in FIG. 9 are denoted by the same reference numerals, and the explanation thereof will be omitted as appropriate.

This article supply device includes two frames 21. The two frames 21 are arranged above the rear side (right side in FIG. 1) of the top chain 11 and on both sides in the width direction thereof. As shown in FIG. 2, shafts 22 are attached to the tips of the two frames 21, respectively. A gear 23 and a sprocket 24 having a somewhat larger diameter than the gear 23 are rotatably attached to the shaft 22. Although not shown, the rear ends of the two frames 21 are each provided with a shaft and a gear rotatably attached to the shaft. A timing belt 25 is provided between this gear (not shown) and the gear 23.
are provided for each. The upper sides of the two timing belts 25 are supported by a support plate 26 formed integrally with the frame 21.

Above one frame 21 is a guide side plate 31.
is located. A shaft 32 is attached to a predetermined location on the guide side plate 31. The shaft 32 has
A first lever 33, which also serves as a balancer, is attached at a predetermined location so as to be swingable. A shaft 34 is attached to the tip of the first lever 33. A second lever 35 and a first pressing roller 36 are attached to the shaft 34 so as to be able to rotate independently of each other. The tip of the second lever 35 has a shaft 3
7 is installed. A second press roller 38 is rotatably attached to the shaft 37.
The first and second pressing rollers 36 and 38 are prevented from being lowered to positions other than those shown in FIG. There is.

Although not shown, the two timing belts 25 transmit the driving force for running the top chain 11 via a clutch brake or the like.
It is designed to run in the same direction as the top chain 11. This clutch brake (not shown) includes first to third sensors 41 to 43, which will be explained later.
It has come to be controlled by

When the heavy cake 13 is fed by this article feeding device, first, as shown in FIG. place Next, when a power switch (not shown) is turned on, the brake is turned off and the clutch is turned on, causing the timing belt 25 to run in the direction of arrow B, and the lump of heavy cake 13 to be attached to the guide side plate 31.
It is transported in the same direction while being guided by.

When the leading portion of the mass of heavy cake 13 pushes up the first pressing roller 36 and passes under it, as shown in FIG. (also the same sensor) detects the leading edge of the chunk of heavy cake 13, which turns off the clutch and turns on the brake, stopping the timing belt 25. In this state, the foremost piece 13a of the heavy cake 13 pushes up the second press roller 38 and pushes up the sprocket 2.
It is located just before 4.

Since the first and second press rollers 36 and 38 are vertically movable independently of each other, no problem occurs even if the heights of the heavy cakes 13 are different from each other. Note that the first and second press rollers 36 and 38 are lifted and the heavy cake 1 is removed.
The mass 3 may be in the state shown in FIG. 4 from the beginning. In this case, the first sensor 41 is not necessary.

Next, when a start switch (not shown) is turned on, the top chain 11 begins to run in the direction of arrow A. When the top chain 11 or the partition piece 12a passes a predetermined position as the top chain 11 moves,
The second sensor 42 detects this, thereby turning off the brake and turning on the clutch, causing the timing belt 25 to run in the direction of arrow B and at the same time, the sprocket 24 to rotate in the direction of arrow C.

Then, as shown in FIG. 5, the foremost heavy cake 13a rides on the sprocket 24 while pushing up the second press roller 38. At this time, since the circumferential speed of the sprocket 24 is faster than the running speed of the timing belt 25, the front heavy cake 13a and the next heavy cake 13b are separated smoothly and reliably, and the next heavy cake 1
3b is pressed down by the roller 36, thereby preventing the heavy cake 13a from following.

This separated foremost heavy cake 13a is
As shown in FIG.
Falling towards 1. This fall is caused by the third sensor 4
3, which turns the clutch off and the brake on, stopping the timing belt 25. In this state, as shown in FIG. 7, the foremost heavy cake 13a falls onto the top chain 11 and is placed thereon. Further, the next heavy cake 13b pushes up the second press roller 38 and rides on the sprocket 24 to some extent, but is held down by the second press roller 38 and is prevented from falling forward due to inertial force. Also, the next heavy cake 13c is,
By being pressed by the first pressing roller 36, it is prevented from falling forward due to inertial force.

The next partition piece 12b of the top chain 11 is the second
When detected by the sensor 42, the next heavy cake 13b falls onto the top chain 11 and is placed thereon in the same manner as described above. The heavy cakes 13 fed one by one between the partition pieces 12 of the top chain 11 in this way are pushed and conveyed by the partition pieces 12 of the top chain 11, as shown in FIG. 8, for example. The package is then sent to a packaging device (not shown) and packaged.

[Effect of idea]

As explained above, according to the present invention, a sprocket and two pressing rollers are provided at the tip of the conveying means, so that in addition to heavy cakes, elastic and sticky cakes such as castella cake and Baumkuchen are placed between each partition of the conveying device. Since the articles can be reliably separated and supplied one by one, labor can be saved.
