Description

Description: TECHNICAL FIELD The present invention relates to an apparatus used for automatically supplying a set of sheet-like articles after a set of leaning sheet-like articles. is there.

[Prior arts and problems to be solved by the invention]

For example, when a set of sheet-like articles (C ₀ ) leaning against the front end of the transport path (1) are sent to the next step one by one from the front side, the number of sheet-like articles gradually decreases, In order to continuously perform the work in the next step without stopping, it is necessary to supply the next set of sheet-like articles (C ₁ ) to the rear side.

In such cases, replenishing the next sheet-like article by hand is the most primitive, but extremely inefficient.

Therefore, it is conceivable to push the next set of sheet-like articles (C ₁ ) leaning on the transport path (1) with a pushing member such as a pusher, but it is possible to prevent them from falling on the transport path (1). A technical problem remains where and how to install the preventive measures. That is, it is difficult to attach the means for preventing the fall, and even if it is attached, the mechanism will be extremely complicated.

The present invention aims to eliminate such drawbacks.

[Means for Solving the Problems]

In order to achieve this object, in the present invention, at least a sheet-like article leaning on the transport path (1) can be passed over the transport path (1), and on the transport path (1). Two inner and outer magazines (A) and (B) having different sizes so that one magazine can pass through the other magazine are arranged so as to be movable in the front-rear direction of the transport path (1). Of the two magazines (A) and (B) inside and outside, in a state where a large number of sheet-like articles to be replenished are leaned on the conveyance path (1) at the rear and front ends of one magazine (B). A pushing member (10) for holding and pushing a large number of the sheet-shaped articles afterward when the magazine (B) is moved forward and a support member (11) for supporting the front end portion of the sheet-shaped articles are provided, and the other one is provided. Magazine (A)
At the front end of the magazine (A), while moving forward as the magazine (A) gradually advances, it supports the rearmost one of a large number of sheet-like articles located in front of this, and after the sheet-like article Another magazine to continue (B)
After a large number of sheet-like articles have been replenished by, the large number of sheet-like articles held by the magazine (B) are retracted as the magazine (A) is retracted with respect to the magazine (B). A support member (7) for supporting the rearmost one is provided.

[Action]

First, as shown in FIG. 3, the first set of sheet-like articles (C ₀ ) is supplied to the conveying path (1) in a leaning state, and the front and rear ends thereof are located at the front end of the magazine (B). It is supported by the supporting member (11) and the pushing member (10) located at the rear of the magazine (B), and is held in the magazine (B).

When the magazine (B) advances, the pushing member (1
In (0), it is sent to the right in the figure on the transport path (1), but the front end of many sheet-like articles (C ₀ ) leaning on the transport path (1) is supported by the support member (11). Because it is
These will not fall.

Another magazine (A) near the front end of the transport path (1)
Is waiting, so the pushing member (10) of the magazine (B)
The set of sheet-shaped articles (C ₀ ) pushed forward by is pushed into the waiting empty magazine (A) (fourth).
Figure).

At this moment, the magazine (A) retreats as shown in FIG. 5, and the last of the set of sheet-like articles (C ₀ ) supported by only the pushing member (10) of the magazine (B) until now. The article is also supported by the support member (7) attached to the front end of the empty magazine (A), and even if the magazine (B) is retracted as shown in FIG. The sheet-like article (C ₀ ) does not fall to the rear side.

In this way, the set of sheet-like articles (C ₀ ) transferred from the magazine (B) to the magazine (A) is moved by the forward movement of the magazine (A), as shown in FIG. Are sent to the front end of the sheet, and the sheets from the front side are sent to the next step one by one. The magazine (A) is also advanced by one sheet-like article every time one sheet-like article at the front end of the transport path (1) is sent out.

When the number of sheet-like articles (C ₀ ) held at the front end of the transport path (1) decreases, it is necessary to replenish the next sheet-like article from the rear side. Then, as shown in FIG. 7, the next set of sheet-like articles (C ₁ ) is supplied to the empty magazine (B) which is retracted, and the magazine (B) is advanced to be shown in FIG. As described above, the sheet-like article (C ₀ ) located at the front end of the conveying path (1) is conveyed to a position following the sheet-like article (C ₀ ).

At this moment, the magazine (A) retreats as shown in FIG. 9, and the supporting member (which supports the many sheet-like articles (C ₀ ) located at the front end of the transport path (1) from the rear side until now ( 7) becomes to support the last _{one of the} subsequent set of sheet-like articles (C ₁ ). Then, when the magazine (B) is retracted as shown in FIG. 10, the next new set of sheet-like articles (C) is placed after the sheet-like article (C ₀ ) located at the front end of the transport path (1). ₁ ) will be supplied.

By repeating this operation, the next new sheet-shaped article can be automatically replenished to the rear side of the sheet-shaped article on the transport path (1) one after another.

〔Example〕

 Embodiments of the present invention will be described with reference to the accompanying drawings.

On both left and right sides of the conveyance path (1) extending in the left-right direction in FIG.
Two rails (2), (2), inside and outside,
(2 '), (2') are provided, and the inner rails (2 '),
In (2 '), the wheels (a) and (a) of the inner magazine (A) of the two inner and outer magazines (A) and (B) having substantially arcuate side surfaces, and the outer rails (2) and (a) are used. In (2) there is another wheel on the outer magazine (B) (b)
The two magazines (A) and (B) inside and outside
Can be moved back and forth along the transport path (1). Two internal and external magazines (A) and (B) for the transport path (1)
In the embodiment, as means for moving the chain in the front-back direction, the two endless chains (3), inside and outside, are provided along the transport path (1).
(4) is arranged so that the hem of the inner magazine (A) is fixed to the inner chains (3) and (3), and the hem of the outer magazine (B) is fixed to the outer chain (4). , A case where both chains (3), (4) are made to run in the left-right direction of FIG. 1 will be exemplified. Then, the chain (3) is mounted on the chain (3) when the chain (3) is run by the air motor shown in (5) of FIG. 1 and the chain (4) is run by the gad motor shown in (6) of FIG. 1, for example. The magazine (A) and the magazine (B) attached to the chain (4) move in the front-back direction of the transport path (1). The motor for driving the chains (3), (4) is not limited to the above. Further, the forward and backward movements of the magazines (A) and (B) are not limited to the above-mentioned mechanism, and may be performed by, for example, a cylinder.

Inside the two magazines (A) and (B), the inner magazine (A) has two left and right support members (7a) on the upper front end.
(7a), and in the middle of the magazine (A), two left and right long holes (1 ') and (1') are cut out in the front-back direction of the transport path (1) so that two faces are left and right. Attach the support members (7b) and (7b). Each support member (7a),
As shown in FIG. 2, (7b) is pivotally attached by one pin (8), and the support member (7a) is attached to the timepiece of FIG. 1 by the spring (9) wound around each pin (8). The support member (7b) is biased in the needle direction and in the counterclockwise direction in FIG. That is, the upper and lower support members (7a) and (7b) are urged in the tightening direction with respect to the traveling direction of the transport path (1). Each of the supporting members (7a) and (7b) supports the rearmost one of a large number of sheet-like articles leaning on the conveying path (1), which will be described in detail later. The support members (7a) and (7b) may be provided on only one of them, but it is better to be provided on both the upper and lower sides. Since the support members (7a) and (7b) provided on both the upper and lower sides can reliably support a large number of sheet-like articles leaning on the transport path (1) from two directions, the sheet-like shape. The article can be prevented from falling. Also,
If the support members (7a) or (and) (7b) are provided on both the left and right sides as shown in FIG. 2, not only the sheet-shaped article will not fall further, but also the sheet-shaped article on the transport path (1) is moved in the left-right direction. It is possible to reliably move forward without slipping.

On the other hand, at the rear part of the outer magazine (B), there is a pushing member (10).
In addition, a support member (1
1) Install. The pushing member (10) plays a role of supporting the rearmost one of a large number of sheet-like articles leaning on the conveying path (1) and pushing it from the rear, and the supporting member (11) serves to push the sheet-like articles. They are supported from the front side, but they will be explained in detail later. In the embodiment, the supporting member (11) is composed of a vertically movable pressing piece, but instead of this, the supporting member (7a) of the magazine (A),
It can also be something like (7b). As a means for moving the support member (11) up and down, a cylinder (12) is used in the embodiment, and by its operation, the support member (11) moves up and down along the guide rod (13) with respect to the magazine (B). I am doing it.

In the embodiment as a sheet-shaped article, a rectangular tube-shaped container (C) for storing milk, juice and the like as shown in FIG. 12 is folded so as not to be bulky and a sheet (C ′) is provided as shown in FIG. However, the sheet-like article in the present invention is not limited to this type,
It may be just one piece of paperboard. Also, the material is not limited to paper,
Synthetic resins and various other types are conceivable, and their application range is extremely wide.

Next, the operating state of the device shown in the embodiment will be described in the order of steps.

First, as shown by a chain line in FIG. 1 and a solid line in FIG. 3, a first set of sheet-like articles (C ₀ ) is leaned (
(Fig. 12) is fed onto the conveying path (1), and its front and rear ends are composed of a supporting member (11) located at the front end of the magazine (B) and a pushing member (10) located at the rear of the magazine (B). Supported. In addition, one set of sheet-like articles (C ₀ ) is fed to the transport path (1).
The above-mentioned supply can be performed by carrying a set of sheet-like articles (C ₀ ) from another place by a holding device (not shown).

When the gad motor shown by (6) in FIG. 1 operates in this state, the endless chain (4) runs in the direction of the arrow in FIG. 3, and the magazine (B) attached to it moves forward,
A set of sheet-like articles (C ₀ ) on the transport path (1) is pushed by the pushing member (10) of the magazine (B) and is fed to the right in the figure. In this case, since the front end of one set of sheet-like articles (C ₀ ) is supported by the supporting member (11) of the magazine (B),
These will not fall.

Another magazine (A) near the front end of the transport path (1)
Is waiting, so the pushing member (10) of the magazine (B)
The set of sheet-like articles (C ₀ ) pushed by is pushed into an empty magazine (A) waiting as shown in FIG.

At this moment, the air motor (5) is activated and the endless chain (3) runs in the direction of the arrow in FIG. Therefore, the magazine (A) attached to the chain (3) is retracted as shown in the figure, and a set of sheet-like articles that have been supported only by the pushing member (10) of the magazine (B) until now. (C ₀ )
The last one will be supported by the supporting members (7a) and (7b) attached to the front end of the empty magazine (A) that has retracted, and as shown in FIG. 6, the magazine (B). Even if the sheet moves backward, the set of sheet-like articles (C ₀ ) does not fall to the rear side. When the magazine (A) retracts, the tips of the supporting members (7a) and (7b) come into contact with the upper end surface and the lower end surface of the set of sheet-like articles (C ₀ ) and the spring (9).
The support members (7a) and (7b) do not get caught on the sheet-like article because they open outwardly around the pin (8) while countering the twisting force of the sheet-like article. The outward direction here means
In the case of the support member (7a), the counterclockwise direction is shown in FIG. 1, and in the case of the support member (7b), the clockwise direction is shown in FIG. 1, and both support members (7a) and (7b) are centered on the pin (8). In both cases, the magazine (A) can be retracted by opening it outward. Further, when the magazine (B) is retracted, the supporting member (11) attached to the front end of the magazine (B) is moved up by the cylinder (12) along the guide rod (13) as shown by the chain line in FIG. It does not get caught on the shaped articles.

In this way, the set of sheet-shaped articles (C ₀ ) transferred from the magazine (B) to the magazine (A) travels the chain (3) by the operation of the air motor (5) after that (see FIG. 6). The sheet is sent to the front end of the conveying path (1) in the direction of the arrow), and the front side of the sheet is picked up one by one by an ejection device (D) and sent to the next step. In the case of the embodiment, the front side of the sheet-like article (C ₀ ) is supported by the projecting device (D) and does not fall down, and the sheet-like article is prevented by the projecting device (D) as shown in FIG. (D) and the guide plate (e) in front of the stopper (there is a gap of about one sheet-like article) to be sent to the next step. Every time one sheet-like article at the front end of the transport path (1) is pushed out, the magazine (A) also advances by one sheet-like article. In the embodiment, the drive source is the air motor (5), but a torque motor may be used instead. By using such a motor, the supporting member (7a) of the magazine (A),
The force of (7b) pushing the sheet-like article can be changed according to the number of sheets. That is, when there are a large number of sheet-like articles in front of the supporting members (7a) and (7b), the supporting members (7a),
(7b) strongly presses the sheet-like article, and conversely, when the number is small, the pushing force can be adjusted to be small.

The sheet-like article at the front end of the transport path (1) is moved to one by the pop-out device (D) provided immediately before the transport path (1).
While the sheets are being picked up one by one, as shown in FIG. 7, the next set of sheet-like articles (C ₁ ) is supplied to the retracted empty magazine (B). Then, when the gad motor (6) is driven to drive the chain (4) in the direction of the arrow in FIG. 7, the magazine (B) advances as shown in FIG. Therefore, the next set of sheet-like articles (C ₁ ) is conveyed to a position following the sheet-like article (C ₀ ) located at the front end of the conveying path (1).

At this moment, the air motor (5) is driven in the opposite direction and the chain (3) runs in the direction of the arrow in FIG. Therefore, the magazine (A) attached to this is retracted as shown in the figure, and until now supports a large number of sheet-like articles (C ₀ ) located at the front end of the transport path (1) from the rear. Support member (7a),
(7b) comes to support the trailing one of the subsequent set of sheet-like articles (C ₁ ). Then, the support member (11) located at the front end of the magazine (B) ascends along the guide rod (13) by the operation of the cylinder (12) as shown by the chain line in FIG. 9, and the gad motor (6). Drive in the opposite direction and the chain (4) travels in the direction of the arrow in Fig. 9,
The magazine (B) attached to this is retracted as shown in FIG. Thus, the next new set of sheet-like articles (C ₁ ) is supplied after the sheet-like articles (C ₀ ) located at the front end of the transport path (1).

By repeating this operation, the next new sheet-shaped article can be automatically and successively supplied to the rear side of the gradually decreasing sheet-shaped article.

When the magazines (A) and (B) are moved forward and backward, the wheels (a) and (b) attached to the magazines are arranged on the left and right sides of the conveyance path (1) along the rails. Since the magazines (2), (2), (2 ') and (2') travel while rotating, the magazines (A) and (B) can travel very smoothly. Also, magazine (A),
(B) The forward and backward positions are detected by sensors (not shown), and the air motor (5) and the gad motor (6), which are drive sources, are driven, respectively, so that the above work can be performed reliably. Not only can it be done, but as the number of sheet-like articles in front of it supported by the supporting members (7a) and (7b) of the magazine (A) decreases, this is quickly detected by the above sensor, and the rear side The following new sheet-shaped articles can be supplied one after another.

In other drawings, as in the case of the supporting member (7b) of the magazine (A), (14) [Fig. 1] shows a part of the face from the upper surface of the conveying path (1). The supporting member mounted so as to extend, when the magazine (B) is at the position shown by the solid line in FIG. 1, the supporting member (1
1) and support the front end of the set of sheet-like articles supplied to the magazine (B). When the magazine (B) advances and one set of sheet-like articles passes over this support member (14), it rotates around the pin (8) against the torsional force of the spring (9), and the conveyance path Immerse under the upper surface of (1). After passing the sheet-like article, the supporting member (14) again faces the conveying path (1).

〔The invention's effect〕

According to the present invention, the following new sheet-shaped article can be automatically and efficiently replenished to the rear side of the sheet-shaped article on the transport path (1). Therefore, when connecting this device and the device for performing the work of the next process back and forth,
The work of the next step can be continuously performed without stopping.
