Description

[Detailed Description of the Invention] This invention relates to a conveyor used, for example, when transporting products in a production line.

Roller conveyors, belt conveyors, etc. are generally used to transport objects. Among these, roller conveyors cannot transport objects unless they are tilted, and there is no other way to reliably control the moving speed of the object than by controlling the speed of movement of the object by changing the angle of inclination. I couldn't go. Furthermore, when conveying an object using a belt conveyor, the belt conveyor is driven by a motor, so the conveyance speed of the object can be controlled relatively easily. but,
When this belt conveyor is used for product management or product processing, multiple objects are conveyed at the same time by the belt, so it is easy to remove rejected items or carry out necessary processing operations. If the target object is temporarily stopped, the preceding object is pushed and tilted by the following object, causing the belt to become cluttered with products.

Moreover, these conventional conveyors require a large number of interlocking devices and installation space, and have the disadvantage of generating noise.

The present invention was developed in view of the above-mentioned points, and its purpose is to easily control the conveyance speed of objects so that even if the target object is temporarily stopped, the remaining objects in multiple rows will not be disturbed. To provide a conveyor that can be moved freely without generating noise, can be easily multi-lined and branched, can mutually transport goods in different directions, can share parts, and is therefore inexpensive and does not generate noise. It's in the.

The details of one embodiment of the present invention are shown in Figures 1 to 4 below.
This will be explained according to the diagram.

1, for example, has left and right side plates 2a, 2 inside the machine frame 2.
This is a drive main shaft arranged in the longitudinal direction along a, and this drive main shaft 1, for example, transfers the driving force of a motor 3 to a sprocket 4 provided on a motor shaft 3a and a sprocket 5 provided on the drive main shaft 1 itself. By suspending each chain 6, the rotation of the motor 3 is driven. 7a ₁ , 7a ₂ ,
7a ₃ , 7a ₄ ... are rotated so that the rotation directions are different between the pair of side plates 2a of the machine frame 2 and the partition plate 8 provided along the longitudinal direction at the center of the side plates 2a, 2a. It is a freely installed rotating shaft. As a means for constructing the rotating shafts 7a ₁ , 7a ₂ , 7a ₃ , 7a ₄ . . . , for example, the side plate 2 of the machine frame 2
accommodating recesses 9a, 10a, 9a are arranged in the longitudinal direction of the upper surfaces of the mounting frames 9, 10, 9 provided on the upper surfaces of the partition plates 8 and 8, respectively. , 10a, 9a are fitted with a bearing material 11 having substantially the same external shape, and both ends of the rotating shafts 7a ₁ , 7a ₂ , 7a ₃ , 7a ₄ . It is inserted loosely.

Further, the rotating shafts 7a ₁ , 7a ₂ , 7a ₃ , 7a ₄ . . . have drive belts 13a, 13b, 13 wound around the pulley 12 attached to one end thereof and the drive main shaft 1.
c, 13d, . . . , the adjacent shafts rotate in different rotation directions and follow the rotation from the common drive shaft 1 in the same manner as the rotation from the motor 3 follows. 14, 15 are rotating shafts 7a ₁ , 7a ₂ , whose rotation directions are different in the axial length direction.
7a ₃ , 7a ₄ . . . are a plurality of cylindrical rollers that are rotatably loosely inserted into each of the rollers 14, 7a 4, and so on.
At least a part of the inner periphery of the rotating shaft 7a ₁ ,
The rotation shafts 7a ₁ , _{7a 2 ,} 7a 3 , 7a ₄ ... are driven by friction by contacting the outer circumferences of the shafts 7a ₂ , 7a ₃ , 7a ₄ ....

In this case, the rollers 14 and 15 of different sizes and diameters rotate in different directions in the same lines A ₁ and A ₂ , respectively. Reference numeral 16 denotes an object to be transported, and the object 16 is, for example, a bottle, a packaging container for cosmetics, an electronic component, a component of a device, or the like.

One embodiment of the present invention has the above-mentioned configuration,
The object 16 is transported as follows.

That is, when the motor 3 rotates, this rotation is transmitted to the drive main shaft 1 via the sprocket 4, chain 6, and sprocket 5, so that the drive belts 13a, 13b, 13 wound around the drive main shaft 1 are
c, 13d... to the left and right side plates 1 of the machine frame 2.
The rotating shafts 7a ₁ , 7a ₂ , 7a ₃ , 7a ₄ .
Since 3d... is suspended in different directions, 2
Adjacent rows in the advancing direction rotate in different directions. Therefore, the rotating shafts 7a ₁ , 7a ₂ , 7a ₃ , 7a ₄ ...
A cylindrical roller 1 of different sizes and diameters is loosely inserted into the
4 and 15, a part of the inner circumference thereof is the rotating shaft 7a ₁ , 7a ₂ ,
By coming into contact with 7a ₃ , 7a _{4 .} . . , driving forces in different directions are applied, and the shafts rotate in opposite directions.
Therefore, the object 16 placed on the large-diameter roller 14 is conveyed along the two lines A ₁ and A ₂ in the direction of rotation of the large-diameter roller 14, that is, in the direction of arrows A and B in FIG. In this case, the small-diameter roller 15 rotates in a different direction from the large-diameter roller 14, but since the object 16 is placed on the large-diameter roller 14 and does not come into contact with the small-diameter roller 15, it is involved in transportation. do not. Also, the fact that the small diameter roller 15 is interposed between the large diameter rollers 14, 14 that contribute to the transportation of the object 16 means that if the small diameter roller 15 were not provided, the large diameter rollers 14, 14 would make it difficult to handle. This is to ensure safety, such as preventing the conveyor from being accidentally pinched, and to prevent unsightly appearance, such as the drive mechanism inside the conveyor being exposed from the outside.

Further, in this embodiment, the large diameter roller 14 that contributes to the transportation of the article and the small diameter roller 15 that does not contribute to the transportation of the object 16 are arranged on adjacent rotating shafts 7a ₁ , 7a ₂ , 7a ₃ , 7a that rotate in different directions. _4. This is done by loosely inserting the large diameter roller 14 into...
The order in which the small-diameter rollers 15 and 15 are combined is not limited to being adjacent to each other. Moreover, the left and right side plates 1a, 1
A rotating shaft 7 installed between a and the partition frame 8
Drive belts _13a , 13b, 1 wound between a 1 , 7a 2 , 7a ₃ , 7a ₄ ... and the drive main shaft ₁
It goes without saying that by changing the winding direction of rollers 3c, 13d, . . . , the rotation direction of the large diameter roller 14 and the small diameter roller 15 can be easily changed.

In addition, when stopping a desired row of objects 16 due to product management or product processing needs, the rotating shaft 7 is
Since a ₂ , 7a ₄ . . . are rotated idly, the object 16 is stopped on the large-diameter roller 14, and the following object 16 also presses against the preceding object 16, so that it stops on the large-diameter roller 14 and tilts. First, the transported products are not disturbed as with conventional belt conveyors. This makes it possible to check for defective products and quickly process the products. Furthermore, the objects 16 in the rows that are not stopped are transported freely.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, the two lines A ₁ and A ₂ of the above embodiment are
A line A ₃ in which a large-diameter roller 14 moves in the same direction as the line A ₁ is installed on the extension line of the previous stage,
Further, this embodiment differs from the previous embodiment in that two lines A ₄ and A ₆ in which a large-diameter roller ₁₄ rotates in the same direction as the line A 1 and one line A ₅ in a different direction are provided in the preceding stage. Similarly to line A ₁ , in line A ₃ , a large diameter roller 14, a same diameter roller 14, and a small diameter roller 15 are rotatably installed every other time between the left and right side plates 2a and 2a of the machine frame 2. The drive belts are wound in different winding directions between the main drive shaft 1, which is driven by the rotational force of the motor 3, and the pulleys 12 attached to each rotating shaft, so that rollers of different diameters are formed. 14 and 15 in different directions, and also in the subsequent lines A ₄ and A _{6 ,} the large diameter roller 14 is rotated in the same direction as the drive belts 13a, 13b, 13e wound in the same direction as the line A1. By winding the drive belt, rollers 14 and 15 of different diameters are rotated in different directions to transport the object 16.

Also, in any embodiment, the rollers 14, 15
The rotational speed of the motor 3 can be adjusted by controlling the rotational speed of the motor 3.

As mentioned above, with this invention, it is easy to control the transport speed of the object, and even if the target object is temporarily stopped, the remaining objects can be moved freely without causing any disturbance. In addition, the number of large-diameter rollers involved in transporting objects and their rotational direction can be controlled simply by changing the winding state of the drive belt that is wound around a common drive shaft, making it possible to create multiple rows and branch lines. It is also possible to easily transport items in different directions. Furthermore, a single drive shaft driven by the rotational force of the motor can be shared to rotate a number of rotating shafts installed on the machine frame at right angles to the shaft.
Moreover, the rollers of different sizes and diameters, the rotary shaft that is rotatably fitted loosely into the rollers, and the bearing that rotatably supports this rotary shaft on the machine frame are all the same parts, so parts can be shared and costs can be reduced. .
