BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article stand-up and supply device, and more specifically, it is arranged on the unloading side of a means for conveying a flat article such as a can in a state of being laid down, and the conveying posture in the flat state. The present invention relates to an article standing and feeding device for feeding 90 degrees to 90 degrees and feeding it to the conveying means in the next stage.

[0002]

2. Description of the Related Art As a conventional article stand-up / feeding apparatus, as shown in FIG. 5, for example, a unloading side of a first carrying apparatus 2 for carrying a flat (low height) canister 1 having a substantially cylindrical shape in a lying state. Is provided with a carry-in port 3a of the chute transport path 3 that is curved in a substantially arc shape, while a carry-out port 3b of the chute transport path 3 is
It is opened toward the lower end displaced by about 90 degrees from the carry-in port 3a. Then, the second transfer device 5 is provided at the lower end of the carry-in port 3a.
Is provided. With such a configuration, the canned product 1 in the sideways state is erected by passing through the inside of the chute carrier path 3 by converting its carrier posture by 90 degrees.
That is, the side surface 1a is directed downward, and thereafter, the side surface 1a is naturally dropped and transferred from the carry-out port 3b onto the second carrying device 5 therebelow. Therefore, in the second transport device 5,
The canned product 1 is conveyed in an upright state as shown in the drawing.

[0003]

However, the above-mentioned conventional apparatus has the following various problems. That is, since the distance from the carry-out port 3b of the chute transport path 3 to the transport surface of the second transport device 5 is set to be relatively long in order to accommodate canned goods (articles) of different shapes, the fall time As it is long, the can 1 receives a large impact when dropped. In addition, the canned product 1 has a flat shape and thus has poor stability in the standing state. As a result, it falls further forward, backward, etc., and cannot be transferred on the second transfer device 5 in an upright state. In addition, recently, the shape of such a cylindrical canned product is also changed to the one shown in FIG. ), And in the case of such a type, the above-mentioned problem becomes more remarkable because the stability in the standing state is lower.

The present invention has been made in view of the above background, and an object of the present invention is to securely raise a flat article conveyed in a state of being laid down and transfer it to the conveying apparatus at the next stage. An object is to provide an upright supply device for articles.

[0005]

In order to achieve the above-mentioned object, in the article standing and feeding apparatus according to the present invention, the article standing and feeding apparatus is provided on the carry-out side of a means for carrying flat articles such as cans in a sideways state, and has a substantially arc shape. And a conveyance posture changing means for changing the conveyance posture of the article to an upright state by moving along the conveyance path, and the conveyance posture changing means is arranged below the conveyance posture changing means and stands up. In the article upright supply apparatus including a conveyance means for conveying the article, the conveyance means has a conveyance surface divided into at least a plurality of portions, and the conveyance posture conversion means and the conveyance means are provided at a lower position. Provided is a transfer means composed of inclined conveyor means, and the conveyor means is arranged such that its lower side passes between the divided conveying surfaces and is located further below, and from the conveying attitude converting means. With a receiving plate member for receiving an article of the upright immediately out.

[0006]

The article that has passed through the conveyance posture changing means is automatically converted into the upright state and carried out by moving along the curved surface of the conveyance path. Then, the carried-out standing product is transferred onto the top surface of the receiving plate member immediately after the carrying-out. At this time, since the article comes into contact with the top surface immediately after being carried out, the impact received at the time of contact is small, and the standing state is maintained without falling when the receiving member is transferred to the top surface (delivery device).

Next, since the conveyor means constituting the transfer means is inclined downward, the position of the top surface of the receiving plate member is gradually lowered as it moves forward. As a result, the placed article also gradually moves down. When the forward / downward movement continues, the receiving plate member is positioned below the conveying surface of the conveying device at the next stage, so that the lower part of the article in the upright state abuts against the conveying surface of the conveying means, Separate from the top surface of the plate member. Therefore, after that, it is conveyed while receiving the conveying force from the conveying means side and maintaining the standing state. Further, even when the transfer device is transferred to the transfer device side, the receiving plate member only moves below the transfer surface, so that a particularly large impact is not applied to the article and the transfer is smoothly performed while maintaining the standing state. To be done.

In this example, the height (side surface) as shown in FIG. 1 shows a device for raising a can 1 having a flat tubular shape having a diameter R longer than the width h) and having a winding tightening process only on the lid portion 1b side.

As shown in the figure, the first transfer device 10
Can be conveyed in a state in which the lid portion 1b side of the can 1 is turned down (a state in which the top and bottom are turned upside down from the state shown in FIG. 6B), and the wide endless belt 11 and the belt surfaces on both sides in the traveling direction are used. And a narrow belt 12 arranged in an upright state, and the narrow belt 12 forms a side wall. Although not shown, a pair of narrow belts 1 arranged on both sides
Nos. 1 are arranged in an inverted V shape so that the distance between them is gradually reduced. As a result, the cans 1 that are randomly transported in large numbers on the first transport device 10 are gradually aligned, and when they are finally unloaded from the first transport device 10, they are aligned in a single column. . That is, the first transporting device 10 is a so-called aligning device, and the point is that the cans 1 can be fed one by one to the side of the transporting posture changing device 20 which constitutes a part of the article standing and feeding device of the present invention in the next stage. It should be.

Here, the article upright supply apparatus of the present invention will be described. First, the conveyance posture changing apparatus 20 has a chute conveyance path 21 which is curved in a substantially arc shape, and an inlet 21 thereof.
The a is arranged so as to be continuous with the unloading side end of the first transfer device 10. The other end of the chute transport path 21 is located at the lower end displaced by about 90 degrees from the carry-in port 21a and serves as a carry-out port 21b. That is, the chute transport path 21 is located above (on the carry-in port 21a side) in the horizontal plane and below (on the carry-out port 21b side) in the vertical plane. A pair of guide plates 22 are arranged on both sides of the chute conveying path 21, and a top plate 23 is arranged above the chute conveying path 21 with a predetermined distance therebetween, so that the canned goods 1 are guided to the chute conveying path 21. Move along
You can drop it.

Further, the guide plate 22 is cut out on the carry-out port 21b side of the chute conveying path 21, and a pair of star wheels 24 are arranged in the cut-out space. As shown in FIG. 3, the star wheel 24 is of a flat star shape having a recess 24a whose side surface is cut inward in an arc shape, and the pair of star wheels 24 rotate synchronously to face each other. Canned food between places 24a
It is designed such that the cans 1 are pinched and dropped downward in order from the first canned food 1.

The star wheel 24 is shown in FIG.
As shown in FIG. 2, it is possible to connect to a drive motor 28 via a power transmission mechanism 27 including a gear box 25, a coupling 26, a rotary belt, etc., and the rotation of the drive motor 28 is appropriately decelerated. It is transmitted and is designed to rotate.

A second transfer device 30 is disposed below the chute transfer path 21. The second conveying device 30 is composed of two endless belts 32 provided between the pulleys 31 arranged at the front and rear, and the two endless belts 32 are arranged in parallel at predetermined corners. It is arranged. Then, the side surface 1a of the can 1 which is erected so as to be installed between the two endless belts 32 is placed, and as the endless belt 32 rotates, the can 1 that is placed in the standing state is bottomed. It is transported with the 1d side as the front. Further, in this example, flat side wall plates 33 are formed upright on both outer sides of the two endless belts 32 to prevent the can 1 from being laterally separated during transportation.

In the present example, the two endless belts 32 constitute a conveying surface. For example, the conveying surface is composed of a plate member having a space in the center and is placed on the plate member. The conveying force for the canned food 1 may be given by a pushing finger or the like separately arranged above or on the side of the conveying surface.

Here, in the present invention, the chute transport path 2 is used.
The delivery device 40 is provided between the carry-out port 21b of No. 1 and the second transfer device 30, and receives the canned food 1 sent from the carry-out port 21b, more specifically, the star wheel 24, and maintains its standing state. On the other hand, the transfer is smoothly performed on the second transfer device 30.

That is, the transfer device 40 has a basic structure of a conveyor device arranged in a downward slope from the chute transfer path 21 side toward the second transfer device 30, and specifically, the second transfer device 30. A drive sprocket 41 arranged at a predetermined lower position in a vertical plane between the two endless belts 32 and a driven sprocket 42 arranged at a predetermined position on the back surface side of the chute conveying path 21.
The endless chain 43 is inserted into the space between the endless belts 32, and a receiving plate member 44 having a substantially right triangle shape is attached to the endless chain 43.

The receiving plate member 44 is attached to the endless chain 43 at the center of the oblique side 44a, and the apex angle on the rear side in the traveling direction is made substantially equal to the inclination angle of the endless chain 43. There is. This allows
The top surface 44b of the receiving plate member 44 is substantially horizontal, and is kept horizontal while it is moving forward and downward as the endless chain 43 rotates. Further, as shown in FIG. 3, the top surface 44b of the receiving plate member 44 is
It is cut in a V shape so that the side surface 1a of the curved canned product 1 can be reliably indicated.

The drive sprocket 41 is linked to the same drive motor 28 as that of the star wheel 24 via a drive chain 45 and the like, so that the drive sprocket 41 is continuously rotated at a constant speed. Then, when the canned food 1 is released from the restraining force (holding force) from the star wheel 24a, the top surface 44b of the receiving plate member 44 is positioned immediately below the released canned food 1 as shown in FIG. , The lid portion 1 of the can 1 in which the upright wall surface 44c of the receiving plate member 44 has fallen
It is adjusted so that it is located close to the b side.

Next, the operation of the above embodiment will be described. First, a large number of cans 1 are conveyed on the first conveying device 10 and are sequentially supplied to the conveying posture changing device 20 one by one. Then, the supplied canned food 1 is transferred to the chute transport path 2
It moves so as to slide down along the curved surface of No. 1 and contacts the star wheel 24 in an upright state to temporarily stop the falling movement.

With the rotation of the star wheel 24, the side surface 1a of the can 1 is supported by the recess 24a of the star wheel 24 and gradually moves downward while maintaining the standing state. Then, when the support from the recess 24a is released, it falls downward, but at the same time as the drop, the lower side of the side surface 1a of the can 1 is the receiving plate member 4 of the delivery device 40.
4 is placed on the top surface 44b. During this placement, since the fall distance is short, there is almost no impact,
The canned product 1 maintains the standing state without falling. Moreover,
Since the upright wall surface 44c of the receiving plate member 44 for receiving the next canned food is close to the lid portion 1b side of the canned food 1, even if the canned food 1 is inclined to fall backward, the upright wall surface 44c prevents the canned food from falling. Suppressed.

Next, the canned goods 1 placed on the top surface 44b of the receiving plate member 44 moves as the receiving plate member 44 moves downward while moving forward as the transfer device 40 is rotationally driven. Then, when the top surface 44b moves below the two endless belts 32 of the second transfer device 30, the lower portion of the side surface 1a of the canned product 1 placed on the top surface 44b and transferred is 2 below. The book is brought into contact with and placed on the endless belt 32 of the book. Then, thereafter, the work is carried along the second carrying device 30, and thereby the work of raising and handing over the canned product in the sideways state is completed.

The transfer from the transfer device 40 to the second transfer device 30 is performed by moving the receiving plate member 44 downward from the space between the two endless belts 32. Sometimes, the can 1 is not subjected to any big impact, and it is transferred onto the second carrier while maintaining its standing posture smoothly.

FIG. 4A shows the main part of the second embodiment of the present invention. As shown in the figure, in this example, unlike the first embodiment, the shape of the receiving plate member 44 'of the transfer device 40' is formed so that the tip of the top surface 44'b is lifted slightly upward. It's a face. With such a configuration, the can 1 transferred from the chute transfer path 30 onto the transfer device 40 and being transferred is brought into contact with the standing wall surface 44'c of the receiving plate member 44 'at the rear of the can 1 and is moved forward. The fall is more reliably suppressed. On the other hand, when the can 1 that is thus slightly biased rearward is transferred to the second transfer device 30 side, as in the first embodiment, the top surface 4 is moved.
Since 4'b moves below the endless belt, it can be transferred smoothly without being impacted.
It will not fall at this time. The rest of the configuration and operation are similar to those of the first embodiment described above, and therefore their explanations are omitted.

In each of the above-mentioned embodiments, the device for raising the canned goods has been described, but the present invention is not limited to this, and any kind of article can be raised. Further, the shape is not limited to the cylindrical shape, and the invention can be applied to rectangular shapes and other arbitrary shapes. Further, the sideways / upright state referred to in the present specification means a posture (state) derived from the shape of the article as shown in each of the above-described examples and the drawings, regardless of the top and bottom of the article itself.

Further, needless to say, the shape of the receiving plate member is not limited to the above-mentioned ones.
It suffices that it is possible to transfer to the second transfer device at the next stage while maintaining the standing state obtained by changing the transfer posture by passing through the chute transfer path. The means for suppressing the forward fall of the can of food placed on the top surface is not limited to the inclined surface as in the second embodiment. For example, as shown in FIG. , Receiving plate member 44 "
Various modifications can be made such that the locking piece 45 is erected at a predetermined position on the top surface 44 ″ b of the above.

[0026]

As described above, in the article upright supply apparatus according to the present invention, the upright articles carried out from the conveying attitude changing means are placed on the top surface of the receiving plate member of the transferring means immediately after the carrying out. Therefore, the impact received during the placement is small, and the fall is suppressed during the placement. Further, when the transfer means is transferred from the transfer means to the transfer means, since the receiving plate member moves below the transfer surface of the transfer device, the contact destination of the article is automatically changed. It will not be added, and it will be transferred smoothly while maintaining the standing state. Therefore, the flat-shaped article conveyed in the state of being laid down can be reliably erected and transferred onto the next-stage conveyance device.
