2. Description of the Related Art Conventionally, in a flow production factory or the like, a conveyor device in which a belt-shaped drive chain is hung on a sprocket gear has been widely used in a manufacturing line from intermediate products and semi-finished products to finished products. .

As shown in FIG. 9, for example, such a conveying device includes a plurality of sprockets 102 around which an endless drive chain 101 is wound, and the endless drive chain 10.
And a drive bracket 103 fixed to 1.
Non-conveyed products such as the intermediate products, semi-finished products and finished products are suspended from the drive bracket 103.

In such a transporting device, the length of the drive chain 101 and the position of the sprocket 102 are adjusted, and further, a plurality of the sprockets are rearranged so that the desired transporting route and transporting route can be obtained. It is used according to.

[0005]

By the way, in the case where the above-mentioned transporting device is used in a large space, it is effective to change the transporting route and the transporting route by rearranging a plurality of the transporting devices. However, when the sprocket 102 is used in a relatively narrow space or incorporated in a relatively small-sized device, the conveyance path is changed by adjusting the arrangement position of the sprocket 102.

However, in the above-mentioned conventional conveying device,
As shown in FIG. 9, since the drive bracket 103 is fixed toward the outer side of the drive chain 101, even if the arrangement position of the sprocket 102 is changed, the non-conveyed product is not conveyed at the position of the sprocket 102. The suspended drive bracket 103 draws a large elliptical orbit D, and the swing becomes large. As a result,
There was a problem that the frictional noise also increased.

In particular, when it is used by incorporating it in a small-sized device, it is also desired to change the conveying path in a right angle direction. In such a case, the sprocket 10 is used.
Even if the arrangement position of No. 2 is changed, a large elliptical orbit D is drawn in the outer peripheral direction of the sprocket 102 at the position of the sprocket 102, which is not suitable for changing the conveyance path in the right angle direction. Under such circumstances, the transfer route is changed only by rearranging the plurality of transfer devices described above.

Therefore, the present invention has been proposed for the purpose of providing a conveying device capable of stably conveying a non-conveyed article to be conveyed even when the conveying path in the right angle direction is changed. Is.

In addition, below, although the conveyance apparatus 70 applied to this balloon vending machine will be described, it goes without saying that the present invention is not limited to the application to this balloon vending machine.

As shown in FIG. 1, the overall structure of the carrying device 70 according to the present embodiment includes first to third sprockets 58 to 60 around which an endless drive chain 57 is wound, and the endless drive. A drive bracket 56 which is positioned and fixed on the inner peripheral side of the chain 57, and two sprocket wheels 59 and 60 of the same diameter among the plurality of sprocket wheels are arranged in the vertical direction and parallel to these sprocket wheels. At least one sprocket 58 is arranged at any position, and the drive bracket 56 is configured to fixedly support the support shaft 55 connected to the conveying means for conveying non-conveyed articles.

First, unlike the conventional one, the drive bracket 56 is positioned and fixed on the inner peripheral side of the endless drive chain 57. That is, as shown in FIG. 2A, the endless drive chain 57 includes a roller link 71 fixed by two bushes fitted with rollers and a pin link 73 fixed by a pair of two pins 72. The drive bracket 5 is a long chain that is connected alternately.
6 is fixed to one of the plurality of pin links 73 via the pair of pins 72 on the inner peripheral side of the endless drive chain 57. And this drive bracket 56
In the center of the above, a support shaft 55 connected to a conveying means for conveying non-conveyed products is fixedly supported.

The drive bracket 56 is not limited to the above structure as long as it is positioned and fixed on the inner peripheral side of the endless drive chain 57. For example, FIG.
As shown in FIG. 2, the pin 72 may have a substantially square shape with the positions of the pair of pins 72 as the bases, or FIG.
As shown in (c), it may have a substantially semicircular shape, and may further have the one shown in 2 (a) above. The drive bracket 56 shown in FIGS. 2B and 2C is provided with a step portion 56a for avoiding contact between the support shaft 55 and the drive chain 57 as much as possible.

The drive chain 57 includes the charging section 28.
Large sprocket 58 disposed above the
And a second and a third having the same diameter, which are vertically arranged at the upper position corresponding to the elastic locking member 43 that divides the balloon guide member 41 into the balloon transfer portion 44 and the balloon storage portion 17.
It is mounted between the sprockets 59 and 60.

Further, the first to third sprockets 58 are provided.
Nos. 60 to 60 are rotatably supported by supporting shafts erected on the equipment frame 38, and as shown in FIG.
The sprocket 59 is driven to rotate by the drive gear 61A. The drive gear 61A is meshed with the drive gear 61B that is rotationally driven by the drive motor 62. Also,
The drive shaft 62A to which the drive gear 61B is fixed is supported between the device frames 38, and one end thereof penetrates one device frame 38A and is rotationally driven by the drive motor 62.

Further, the second sprocket 59 and the third sprocket 59
The sprockets 60 have the same radius R and are arranged in the vertical direction. Then, at a position of the same height, which is located in parallel with the lower third sprocket 60, the first sprocket 59 and 60 having a diameter larger than those of the first sprocket 59 and 60.
Sprocket 58 is arranged.

The support shaft 55 is used for the balloon guide member 4
The support member 40b is arranged orthogonal to the nozzle member 1 and the supporting member 40b is fitted to the support shaft 55, so that the nozzle member 40
Is supported in a drooping state. The drive bracket 56 that fixedly supports one end of the support shaft 55 is assembled to a part of the endless drive chain 57.

In particular, in the present embodiment, as shown in FIGS. 3 and 4, the position of the pair of pins 72 of the drive bracket 56 is set as the base position, and one end of the drive bracket 56 from this base position. The distance T to the center position 55a of the support shaft 55 that is fixed and supported is substantially the same as the radius R of the second and third sprockets 59 and 60.

This is set in order to suppress the movement locus of the drive bracket 56 to be a little swinging according to these paths even when the conveying path is changed to a right angle or a right angle or more. Then, this enables the movements described below.

In the above description of the embodiment, the drive bracket 56 is provided with the support shaft 55, but the drive bracket 56 is provided with a chucking member (not shown) for chucking a non-conveyed product. It may be provided so that the non-conveyed product is attached and detached.

Next, the carrying state of the carrying apparatus having the above construction will be described together with the construction of the above-mentioned balloon vending machine.

A support shaft 55 provided on the drive bracket
As shown in FIG. 1, it circulates inside the drive chain 57 in a clockwise direction (movement locus is indicated by M), but first, in the position where the third sprocket 60 is arranged, the vertical direction (Y
Indicate. ) To the lateral direction (indicated by Z in the drawing) at a right angle, the transport path is changed. In this case, as shown in FIG. 6, the nozzle member 40 supported by the support shaft 55 is provided.
Moves downward from the position corresponding to the second sprocket 59 toward the balloon storage portion 17, and the balloon guide member 41
When the balloon material 30 is caught by entering the guide slit 45 of the balloon guide member 45, as shown in FIG.
The balloon material 30 is moved along the guide slit 45 of FIG. That is, at the position where the third sprocket 60 is arranged, it is required to change the transport path in the right angle direction with extremely high accuracy.

In the above case, the drive bracket 56 according to this embodiment is positioned and fixed on the inner peripheral side of the drive chain 57. Therefore, the drive bracket 56
Moves along the inner peripheral side of the drive chain 57, and does not rotate in a large elliptical orbit D at the position of the sprocket 102 as in the conventional transfer device shown in FIG. .

That is, when the drive bracket 103 is fixed toward the outer peripheral side of the drive chain 101 as in the conventional device shown in FIG. 9, the nozzle member 40 enters the guide slit 45 of the balloon guide member 41. However, even if the balloon material 30 is caught, it is difficult to move along the guide slit 45 of the balloon guide member 41 and convey the balloon material 30 to the inflating portion 28 because the large elliptical trajectory D is drawn. .

However, the drive bracket 5 according to this embodiment
Since 6 is positioned and fixed on the inner peripheral side of the drive chain 57, the drive bracket 56 is attached to the drive chain 5 described above.
Since it moves along the inner peripheral side of 7, the above movement can be smoothly handled.

Moreover, in the carrying device 70 according to the present embodiment, the interval T between the fixed portion 72 with the drive chain 57 and the fixed portion 55a with the support shaft 55 is equal to the second and third sprockets 59, 60. The radius R is substantially equal to the radius R. Therefore, the drive bracket 56 rotates in the same radius R as that of the third sprocket 60 with respect to the right-angled conveyance path, and thus draws a substantially right-angled trajectory. For this reason, as shown in FIG. 7, when the nozzle member 40 catches the balloon material 30, immediately after the balloon material 40, the stable state with little swing along the guide slit 45 of the balloon guide member 41 toward the inflating portion 28. And, moreover, it is moved accurately.

Next, at the position where the first sprocket 58 is arranged, as shown in FIG. 1, the support shaft 55 is diagonally upward (indicated by X in the figure) from the lateral direction (indicated by Z in the figure). The transportation route will be changed to. in this case,
As shown in FIG. 8, when the balloon material 30 conveyed to the inflating unit 28 is inflated to a predetermined size by helium gas or the like, the nozzle member 40 moves upward, and the nozzle unit 40a moves to the balloon guide. This is a state in which the member 41 comes out of the nozzle guide slit 45 and the engagement state with the nozzle member 40 is released.

In the above case, the drive bracket 56
Will rotate along the diameter of the first sprocket 58, but since the drive bracket 56 according to the present embodiment is provided on the inner peripheral side of the drive chain 57, it rotates in a large elliptical orbit. There is no such thing, and the drive chain 57 moves along the inner peripheral side.

A relatively large space is required for the nozzle portion 40a to come out of the nozzle guide slit 45 of the balloon guide member 41. Even in such a case, according to the present embodiment. The drive bracket 56 moves along the inner peripheral side of the drive chain 57. Therefore, the carrying device according to the present embodiment is particularly suitable for use by incorporating it into a small device.

Next, at the position where the second sprocket 59 is arranged, as shown in FIG. 1, the support shaft 55 is diagonally upward (indicated by X in the figure) and is substantially vertical (indicated by Y in the figure). The transportation route will be changed to. in this case,
At the position of the second sprocket 59, the drive bracket 56 moves and changes vertically from the horizontal X direction to the vertical Y direction and returns to the original position. Note that this angle is set so that the change in movement is larger than that in the case of the right angle state from the Y direction in the vertical direction to the Z direction in the horizontal direction.

In response to the change in the transport path in the above-described substantially vertical state, the drive bracket 103 as in the conventional apparatus shown in FIG.
Is fixed to the outer peripheral side of the drive chain 101, the non-conveyed product can be swung greatly. However, the drive bracket 56 according to the present embodiment includes the drive chain 57.
Is provided on the inner peripheral side of the drive chain 57, and a distance T between the fixed portion 72 with the drive chain 57 and the fixed portion 55a with the support shaft 55.
Is formed to have a radius approximately equal to the radius R of the second and third sprockets 59 and 60. Therefore, as shown in FIG. 4, the drive bracket 57 is in a stable state with a small swing so as to match the inner rotation of the second sprocket 59 even when the drive bracket 57 has a larger change movement than the substantially right angle state. It is moved.

After rotating in this way and returning to the original state, the same movement is repeated again to intermittently convey the balloon material 30 which is a non-conveying article, and to attach and detach it. .

As is clear from the above description, the drive bracket 56 according to the present embodiment is positioned and fixed on the inner peripheral side of the drive chain 57. Therefore, as compared to the conventional device in which the drive bracket 103 is fixed to the outer peripheral side of the drive chain 101, the drive bracket 5
The movement locus of 6 is small, and it is conveyed in a stable state with little shaking. Moreover, the drive chain 5
The distance T between the fixed portion 72 with respect to 7 and the fixed portion 55a with respect to the support shaft 55 is equal to the radius R of the second and third sprockets 59 and 60.
Are formed almost equally. Therefore, the drive bracket 56 does not rotate in a large elliptical orbit even when the conveyance path is changed to a right angle or more, and the state is adapted to the change in the vertical direction. Therefore, the non-conveyed goods can be accurately conveyed in a stable state.

In the above embodiment, the conveying device 7 in which the plurality of sprockets 58 to 60 are arranged in a vertical state is used.
Although described as 0, the present invention is applicable to a case where the plurality of sprockets 58 to 60 are arranged in a horizontal state and at least two sprockets 59 to 60 having the same diameter are arranged to face each other in the left-right direction. However, the moving operation is performed in a stable state and is not limited to the above embodiment. Further, in the above embodiment, the three sprockets 5 are used.
8 to 60 have been described, but it goes without saying that four or more can be applied.

[0041]

The conveyor according to the present invention comprises a plurality of sprockets around which an endless drive chain is wound, and a drive bracket which is fixed on the inner peripheral side of the endless drive chain. Two sprockets of the plurality of sprockets are arranged in the vertical direction, and at least one sprocket is arranged at a position parallel to the lower sprocket in the vertical direction, and the drive bracket is not conveyed. It is characterized in that a support shaft connected to a transfer means for transferring an article is fixedly supported. Therefore,
The drive bracket can be moved along the inner peripheral side of the drive chain, and it is possible to provide a transfer device that can effectively cope with a change in the transfer route even in a relatively small space or a relatively small device.

Particularly, two of the above-mentioned plurality of sprockets are used.
Even if the sprocket is arranged in the vertical direction and at least one sprocket is arranged at a position parallel to the lower sprocket in the vertical direction and a right-angled conveyance path is set, The track of the drive bracket at the position draws this substantially right-angled track, and the non-conveyed product is conveyed in a stable state. Therefore, it is possible to suppress the frictional noise when a non-conveyed product is conveyed, and also it is possible to exert an extremely large effect when the product is used in a relatively narrow space or incorporated in a small device.
