Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article transferring / conveying apparatus for transferring an article being conveyed from a conveying apparatus to a receiving apparatus while the two apparatuses are moving.

[0002]

2. Description of the Related Art In an apparatus such as an automatic filling and packaging apparatus which sequentially goes through each step while conveying an article, a packaged article as an article to be handled in each step and a bag body for packaging the article are delivered and received. Done. For example, a bag feeding device that feeds individual bags to a bag holding and conveying device or a bag holding and conveying device that pulls out a continuous bag in which a plurality of bags is detachably connected by perforations and cuts it off BACKGROUND ART Bags and articles are transferred between two devices that move to each other at many positions, such as a packaged object conveying device that inserts a packaged object into a bag held by an apparatus while the bag is moving. The transfer of the articles is usually performed in a state in which the above two devices are temporarily stopped at the stations of the respective processes. Therefore, the above-mentioned two devices are driven so as to perform an intermittent motion for the transfer of articles.

[0003]

In the above-described automatic filling and packaging apparatus, the bag body is usually hung only in the state of being gripped by the clip body or the like in the vicinity of both side ends of the opening.
It is not supported by other parts. Therefore, after the object to be packaged is put into the bag body through the opening and then taken out as a product, the bag body will be shaken by the impact force each time it is stopped or moved at each station, and the gripping part It may cause stress to concentrate and damage. This is remarkable as the weight of the packaged object is large and the bag body is long in the longitudinal direction. In particular, when a liquid substance is directly injected into the bag body as a packaged object, the liquid substance causes sloshing and adheres to the opening to cause a sealing failure at the time of sealing in a later process or to stain the inner surface of the bag body. . Further, the shocking shaking of the bag body into which the packaged object is put may cause a great force to the clip body or the like, which may be damaged or the bag body itself may drop.

Even if there is no problem such as damage to the bag or defective sealing as described above, the efficiency of filling and packaging is low due to the intermittent operation of the device for suspending the bag. There are other issues as well.

Therefore, in order to solve the above problems,
By performing the constant speed continuous operation of the two devices for exchanging the above-mentioned articles, not the intermittent operation, and exchanging the articles during the movement without giving the impact force due to the intermittent operation to the bag body into which the object to be packaged is introduced. It is conceivable to use a highly efficient automatic filling and packaging machine. Such an automatic filling and packaging device can be realized by moving two devices operating at a constant speed in the transfer position in the same direction at the same speed.

However, when articles are transferred between the two devices instantaneously, it is possible to move them at the same speed in the same direction. However, when it takes a little time to transfer the articles, this is required. Often difficult to achieve. For example,
When the trajectories of the movements of the transfer parts (the transfer part of one device and the reception part of the other device) of two devices that move in a rotary shape draw a circle, the transfer is a point of contact between these two track circles. Can only be done in position. That is, at this position, the transmission / reception parts of both devices can momentarily have the same speed in the same direction (tangential direction), but before and after that, the speeds (peripheral speeds) are the same, but the moving directions of the devices are different from each other. . That is, the relative positions and the relative postures of the two transfer units are constantly changing. Therefore, when it takes some time to transfer an article, it is not possible to transfer the article while operating at a constant speed. That is, when articles are exchanged at several points in the device, even if it takes some time to exchange at one location and constant speed operation is not possible for the above reasons, even if it is possible to instantly exchange at other locations. , I have no choice but to adopt the intermittent exercise method. Such a problem similarly occurs not only in the above automatic filling and packaging apparatus but also in other types of apparatuses.

The present invention solves the problem that the conventional device has, and even when it takes some time to transfer the goods, the transfer parts of the two devices move in the same direction and at the same speed, so that the relative position and the relative position can be improved. An object of the present invention is to provide an article transfer / conveyance apparatus capable of creating a state in which the posture does not change.

[0008]

According to the present invention, it is an object of the present invention to provide an apparatus having a carrier device and a receiver device for delivering and receiving an article while the article is being carried, wherein a transfer section provided in the carrier device is a straight line. Alternatively, the vehicle travels at a constant speed while drawing a circle locus, the receiving section provided in the receiving device travels at the same speed as the transfer section, and part of the path of the receiving section is part of the path of the transfer section. A position adjusting mechanism that adjusts the position of the receiving part of the receiving device or the delivering part of the conveying device so that they coincide with each other and keeps the relative posture of the receiving part and the delivering part constant in the above-mentioned part of the section. Achieved by

[0009]

According to the present invention having such a structure, the transfer section of the conveying device and the receiving section of the receiving device travel at a constant speed in a straight or circular path. When the transfer section and the receiving section are close to each other, the position adjusting device causes the two tracks to coincide with each other in a predetermined section. In the predetermined section, the transfer section and the receiving section travel on the same track at the same speed. Then, after that, it leaves the orbit. The position adjusting device also has a posture adjusting function, and the relative postures of the delivery unit and the receiving unit are constant in the predetermined section.

Thus, the receiving section moves in the above-mentioned section as if it were provided in the conveying device, and the relative position and relative posture with respect to the transfer section do not change. Therefore, the articles can be transferred and received in this section over a relatively long time.

A guide pin 58 is provided at the end of 5. A groove 59 that engages with the guide pin 58 of the lever 55 is formed in the rotating member 56 so as to extend in the longitudinal direction of the lever 55. A shaft 67 that rotatably supports the member 56 is provided. The transfer portion (not shown) is located at the position of the shaft 67, and the rotating member 5
Supported by 6.

The slider mechanism 52B has a slider 66 slidably guided in the radial direction of the rotary plate 51 by a guide groove 51B formed in the rotary plate 51.
One end of is connected by a shaft 67 so as to be rotatable relative to the rotating member 56 of the link mechanism 52A. A cam follower 68 is provided at the other end of the slider 66,
It engages with a cam groove 69A of a stationary cam plate 69 provided in parallel with the rotary plate 51.

From the viewpoint of the transfer of the articles to be wrapped from the second rotation transfer device 50 to the rotary 1 using the position adjusting device 52 from the viewpoint of transfer between the two devices during conveyance of the article, the second rotation is performed. The transfer device is a transport device and the rotary is a receiving device.

Next, the operating principle of the position adjusting mechanism 52 will be described with reference to FIG. 8 is a plan view of the mechanism of FIG. 7 when the upper cam plate 65 is removed.
In FIG. 6, reference numeral 61 indicates a locus circle and a moving direction of movement of the bag body suspension portion of the rotary 1, and reference numeral 62 indicates movement when the delivery portion is not attached to the position adjusting mechanism 52 of the present embodiment. The locus circle and the moving direction shown are shown, and both locus circles 61 and 62 intersect at positions Q and R.

The cam groove 69A of the lower cam plate 69 is
It is formed so as to draw a locus 61A so that the delivery section moves on the locus circle 61 when the delivery section moves from the position Q to the position R. That is, the straight line obtained by connecting the axis 51A and an arbitrary point on the locus circle 61 is the locus circle 61 and the locus 6.
The distance between the points intersecting with 1A is constant. Thus, when the cam follower 68 is guided by the cam groove 69A (not shown), the delivery unit 60 moves on the locus circle 62 and when it reaches the position Q, moves on the locus circle 61 of the rotary 1 and moves to the position R. When it comes to, it comes to move on the locus circle 62 again. When the delivery portion reaches the position Q, the cam groove 57A of the upper cam plate 65 moves from the position q to the position r of the cam follower 57 as the cam follower 57 moves from the position Q to the position R of the delivery portion. Turn to the side,
As a result, as seen from the thick chain double-dashed line in FIG. 8, while the rotating member 56 is extending from the position Q to the position R, it is always at a right angle to the tangent line of the arc QR, and the transfer portion is as if the rotary 1 And is formed as if rotating and moving integrally with the rotary 1.

Thus, the slider mechanism 52B causes the delivery section to move on the locus circle 61 of the rotary 1 when moving from the position Q to the position R, and at the same time, by the rotating member 56 connected to the shaft 67, the shaft 67 moves. The orientation of the delivery portion supported at the position is always constant with respect to the locus circle 61 by the link mechanism 52A.

Then, the bag body falling from the lower section of the rotary discharge device 110 is carried out as a product.

In the apparatus of this embodiment having the above structure,
The packaged object P is packaged in the following manner.

(1) First, the continuous bag pulled out from the unillustrated original fabric is separated into individual bags 3 at the perforations. The bag body supply device 20 shown in FIG. 4 holds three such bag bodies 3 in a state where they are not spaced from each other, and the three bag bodies 3 are moved to each other by rotating the rotating members 21A, 21B and 21C by 180 °. Are delivered to the bag transporting device 10 at intervals of.

(2) Conveying belt 12 of bag conveying device 10
The bag body 3 conveyed by means of the sucker members 31A, 31B, 31C of the first rotation transfer device 30 are sequentially taken out one by one, and when the rotary 1 rotating at a constant speed passes the position 1A, each bag body of the rotary 1 is conveyed. It is delivered to the hanging part. The bag body 3 is hung by the bag body suspension portion of the rotary 1 in order by sandwiching, and passes through the positions 1B, 1C, ... Shown in FIG. 1 at a constant speed.

(3) When the bag body 3 hung at the bag body suspension portion of the rotary 1 passes through the position 1C, the opening device 4 is operated and the opening portion of the bag body 3 is largely opened. . Then, at the position 1D, the members 5A, 5A of the guide device 5 descend and enter the opening of the bag body 3 and then rotate to make the opening wide across the entire width of the bag 3 in preparation for loading.

(4) On the other hand, in the package transfer device 40,
The tray P1 containing the articles to be packaged P is placed and traveling at a constant speed, and the orientation is changed vertically at a position where the tray P1 is close to the second rotation transfer device 50.

(5) The second rotation transfer device 50 has a transfer part, and takes out the package P from the tray P1 whose direction is changed vertically and rotates it at a constant speed and brings it to position 1D in FIG. At that time, the gripping force of the delivery part is released and the bag is dropped into the bag body 3. At that time, as described above with reference to FIGS. 7 and 8, the delivery unit has only a fixed relative position because the traveling locus and the traveling speed are the same with respect to the bag suspension portion of the rotary 1. In addition, the relative posture (direction) with respect to the hanging portion of the bag body is also constant, and it is possible to drop and insert the bag over time.

(6) The rotary 1 continues to rotate at a constant speed,
When the bag body 3 passes through the position 1F, the antiaging agent is put into the bag body 3 from the chute 71.

(7) When the rotary 1 further rotates and passes through the position 1F of the bag body 3, the guide device 5 of the nitrogen sealing device 80.
Widens the opening of the bag body in the thickness direction and the width direction of the bag body, and the thin tube 81 enters therein. After entering the thin tube 81,
The guide device 5 rises and retracts outside the bag body, and tensioning means (not shown) pulls both ends of the opening outward in the width direction. As a result, both inner surfaces of the opening are almost in close contact with each other in the state where the thin tube 81 has entered, and there is no gap. In this state, nitrogen is sealed from the thin tube 81 for a predetermined time, and then the thin tube 81 is pulled out upward. This step of filling nitrogen is performed while one bag body moves from position 1G to position 1J.

(8) When the bag 3 has passed the position 1K after completion of the nitrogen filling, the operation of the sealing device 90 is started, and the opening of the bag 3 is sealed by the pair of heat bars 91A and 91B. This sealing process is similar to the above nitrogen filling.
This is performed while the bag body 3 moves from the position 1K to the position 1N.

(9) Further, when the bag body 3 reaches the position 1O, the positions 1O to 1R are transferred in the same manner as in the above sealing step.
In the meantime, the seal portion of the bag body is cooled by the pair of cooling bars of the cooling device 100.

(10) Thereafter, the bag body 3 is released from the bag body hanging portion at the position 1W and drops, and the rotary discharge device 110
Thus, the product is stored in the receiving tray 121 of the carry-out device 120 and carried out as a product.

The invention is not limited to the illustrated embodiment,
Various changes are possible. For example, a position adjusting mechanism similar to the position adjusting mechanism provided in the second rotation transfer device for making the relative speed and the relative attitude change to zero for a predetermined period of time with respect to the rotary 1 is used for the package transfer device 40. It can be provided in the rotation transfer device. That is, from the viewpoint of the transfer between the two devices during the transfer of the article, the package transfer device is the transfer device and the second rotation transfer device is the receiving device. In that case, since the conveyance path of the packaged body conveying device is a straight line, the shape of the cam groove must be changed to a shape corresponding thereto. By doing so, it is possible to accurately deliver the packaged object from the packaged object transport device 40 to the second rotation transfer device 50 over time. If the first rotation transfer device 30 and the rotary 1 are also provided with the position adjusting mechanism based on the same principle as described above, the delivery can be performed more easily and accurately. Further, the position adjusting mechanism can also store the position in the memory device in advance and move a predetermined member based on the designation signal without depending on the system using the cam as described above.

Furthermore, in the present embodiment, the bag conveying device 1
The transfer between 0 and the first rotation transfer device is performed in a state where the relative speed between them is zero, but it is almost instantaneous. Therefore, when it is desired to secure the time at which the relative speed is zero as long as possible without using the position adjusting mechanism, the traveling path of the bag body transporting device 10 is not made straight and one of the orbit circles of the first rotation transfer device 30 is not used. It is also a measure to form the curved running portion along the portion.

[0048]

As described above, according to the present invention, the bag body is delivered,
Since the transfer process of all the articles such as the insertion seal to the bag of the packaged object is performed in such a state that the cooperating transfer devices do not have the relative speed and the relative posture does not change, It becomes possible to perform each process while continuously operating at a constant speed, and damage to the bag body, seal failure, and the hanging part of the bag body, which were possessed by the conventional equipment equipped with a transfer device that operates intermittently, The problems such as detachment of the article during delivery and the low work efficiency of the delivery process are all ameliorated.
