Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for accurately weighing small articles in a delivery and weighing device for weighing articles while delivering them.

[0002]

2. Description of the Related Art For example, in a line for packaging confectionery such as candy in child bags one by one, the packaging process does not correctly store the confectionery, for example, an empty product or a defective confectionery. There are items that contain only parts, or items that are not connected properly due to the disconnection between the bags.

In order to find such an article and remove it from the line, as shown in FIG. 12 (a), the article W carried out from the run-up conveyor 1 is received by the carrying section 6 of the weighing conveyor 5, and the It is conceivable to use a transport and weighing device that is configured to weigh the weight of the article with the scale 7 during transport.

However, in such a conventional conveying and weighing apparatus, rollers 3a and 3b for feeding the conveying belt 2 of the run-up conveyor 1 and rollers 6b for feeding the conveying belt 6a of the conveying section 6 of the weighing conveyor 5 are provided. Since the diameter of 6c is several tens of millimeters or more even if it is small, the small article W of several centimeters or less as described above falls into the gap between the run-up conveyor 1 and the weighing conveyor 5 and cannot be transferred smoothly.

As a method for solving this, FIG.
As shown in (b) of FIG. 5, it is possible to provide a transfer plate 8 in the gap between the run-up conveyor 1 and the weighing conveyor 5 so that articles do not fall between the conveyors. However, since the transfer plate 8 does not have a force to convey the product by itself only by sliding the product, if the tip of the bag gets into the gap between the transfer plate 8 and the run-up conveyor 1, biting occurs and the bag escapes. It is impossible to do so, and the flow of the subsequent articles is greatly disturbed. In addition, even if the transfer speed of the article on the transfer plate 8 is greatly reduced and the article is transferred onto the weighing conveyor 5, a shock due to the speed difference does not stabilize the posture of the article on the weighing conveyor, and the weighing is performed. There is a problem of causing an error.

As another solution, the run-up conveyor 1
And the diameter of the roller of the measuring conveyor 5 is, for example, 1
It is also conceivable to reduce the length to 0 mm or less to shorten the length of the depressed portion of the gap between the conveyors.

[0007]

However, if the roller diameters of the run-up conveyor and the weighing conveyor are reduced to 10 mm or less, the radius of curvature of the return portion of the belt becomes small, which imposes an excessive force on the belt and shortens its life. In addition, a strong bend was attached during the operation stop period,
There is a problem that the transport speed is greatly uneven and the weighing accuracy is significantly reduced.

The present invention solves this problem and enables even small articles to be transferred from the run-up conveyor to the weighing conveyor smoothly, without imposing a force on the belt, and without causing unevenness in the transfer speed, with high accuracy. It is an object of the present invention to provide a transfer and weighing device capable of weighing.

[0009]

In order to achieve the above-mentioned object, a conveying and weighing apparatus of the present invention comprises a measuring conveyor configured to support a conveyor type conveying section with a measuring device, and the conveying of the measuring conveyor. In a conveying and weighing device that is equipped with a run-up conveyor for loading articles into a section, and measures the weight of articles carried into the transport section of the weighing conveyor from the run-up conveyor by the weighing device, the transport section of the weighing conveyor is at the loading side.

A bearing body 41 is horizontally installed inside the upper portion of one end side (carry-in side) of the both side plates 38. Large-diameter bearing mechanisms 41a are provided at both ends of the bearing body 41 so as to face each other.

A carry-in roller 42 having a small diameter (for example, a diameter of 6 mm) whose diameter is shorter than half the length of the article is rotatably supported by both bearing mechanisms 41a. Carry-in roller 42
As shown in FIG. 6 (b), is supported with its outer circumferences in contact with the inner circumference of the large-diameter bearing mechanism 41a.

A screw support plate 43 bent in an inverted L shape is fixed to the outside of the lower part of one end side (carry-in side) of the both side plates 38. A tension adjusting screw 45 is attached to the horizontal portion 43a of the screw support plate 43 so as to vertically pass therethrough,
Further, a vertical shaft groove 46 is formed in the vertical portion 43b of the screw support plate 43 from the lower end toward the upper side.

A first roller 48 having a larger diameter (for example, 20 mm in diameter) than the carry-in roller 42 is arranged between the vertical portions 43b of the screw support plates 43 in parallel with the carry-in roller 42. Similar to the intermediate roller 35 shown in FIG. 6A, the first roller 48 has a hollow cylindrical body to which bearing mechanisms are fixed, and the cylindrical body rotates about a shaft 49 inscribed in the bearing mechanism. Is configured.

Both ends of the shaft 49 of the first roller 48 pass through the shaft grooves 46 of the screw support plate 43 and are pressed by the lower end of the tension adjusting screw 45 from above.

On the other hand, a bearing body 51, which is the same as the bearing body 41, is laid at the same height and parallel to the other end side (delivery side) of the both side plates 38. Large-diameter bearing mechanisms 51a are provided at both ends of the bearing body 51 so as to face each other. Both bearing mechanisms 51a rotatably support both ends of a carry-out roller 42 and a carry-out roller 52 having the same diameter. Has been done.

Below the carry-out roller 52, the second roller 5
3 are arranged in parallel. The second roller 53 is formed to have the same diameter as the first roller 48, and like the intermediate roller 35 shown in FIG. 6A, the shaft 54 inscribed in the bearing mechanism fixed to both ends of the hollow cylindrical body is provided. It has a structure that rotates to the center. Both ends of the shaft 54 of the second roller 53 are fixed to the side plate 38 by nuts 55.

The conveyor belt 56 of the weighing conveyor 22 is formed in an endless belt shape, one surface of which comes into contact with the outer circumference of the carry-in roller 42, the carry-out roller 52, the second roller 53 and the first roller 48 in this order, and the other. Is laid between the first and second rollers 48 and 53 so as to contact the outer periphery of the intermediate roller 35. An appropriate tension is applied to the conveyor belt 56 by adjusting the tension adjusting screw 45.

A drive belt 57 is stretched between the second roller 53 and the pulley 32 of the drive motor 31. In the drive motor 31, the conveyor belt 56 is used for the carry-in roller
The second roller 53 is rotationally driven at a constant speed so that the second roller 53 is conveyed from the second side toward the carry-out roller 52 side.

A weighing conveyor 2 having such a transport section
In 2, the transport belt 56 is hung from the carry-in roller 42 and the carry-out roller 52 to the first and second rollers 48 and 53 located substantially directly below the carry belt 56, respectively. Even if the diameter is small, the conveyor belt 56 is not subjected to an unreasonable bending force, and a strong curl cannot be applied during the operation stop period.

Since the intermediate roller 35 is provided at a position higher than the first and second rollers, the contact angle between the first and second rollers 48 and 53 and the conveyor belt 56 can be increased, The rotational force of the second roller 53 can be efficiently transmitted to the conveyor belt 56.

The intermediate roller 35 is a conveyor belt 56.
On the other hand, since it is in contact with the surface opposite to the other rollers, a force is applied in a direction to correct the bending of the conveyor belt by the other rollers during the operation stop period during driving, so that unevenness in the conveying speed does not occur. .

The weighing conveyor 22 has a side plate 38.
By loosening the bolt 39 holding the shaft and pulling up the carry-in roller 42 side around the shaft 36 of the intermediate roller 35, the distance between the pulley 32 and the second roller 53 becomes short,
The drive belt 57 can be removed, and if the drive belt 57 is removed, the transport mechanism except the intermediate roller 35 is supported by the support plate 25.
It can be removed from the box and maintenance can be performed easily.

On the other hand, as shown in FIGS. 1 and 7 to 10, the run-up conveyor 60 arranged on the carry-in side of the weighing conveyor 22 has a pair of support plates 61 whose lower portion is fixed on the base 21. It is supported above the base 21 by way of.

Inside each of the support plates 61, an intermediate plate 62 formed in a step-like shape is provided horizontally, and a motor support plate 63 is attached to the lower step portion of the intermediate plate 62, and the motor support plate 63 is attached to the motor support plate 63. The drive motor 64 is fixed. A pulley 65 is attached to the shaft 64a of the drive motor 64.

Second support plates 66 are fixed to the upper portions of both support plates 61 so as to face each other. Second
The support plate 66 is bent and formed so that its upper portion is located inside the lower portion, and the side plate 6 to be described later is provided at the upper edge of the upper portion.
U-shaped grooves 68 for fixing 9 with bolts 67 are provided at both ends and the center.

Inside the second support plate 66, a pair of side plates 6 is provided.
9 are arranged so as to face each other, and the both side plates 69 are connected by an underlay plate 70 horizontally extending between the upper ends thereof. The underlay plate 70 receives the load of the article conveyed by the conveyor belt 83 described later and prevents the conveyor belt 83 from hanging down.

A carry-in roller 71 is rotatably supported on one end side (carry-in side) of both side plates 69. Similar to the intermediate roller 35 of the weighing conveyor 22, the carry-in roller 71 is configured such that the shaft 72 passes through the center of the bearing mechanism fixed to both ends of the cylindrical body, and both ends of the shaft 72 are nuts. It is fixed to the side plate 69 by 73.

On the other end side (carrying out side) of the underlay plate 70, a pair of bearing mechanisms 74 are attached so as to face each other. Both ends of a carry-out roller 75 having the same diameter as the carry-in roller 42 of the weighing conveyor 22 are rotatably supported by the bearing mechanism 74. The bearing mechanism 74 has a smaller diameter than the bearing mechanism 41a supporting the carry-in roller 42 of the weighing conveyor 22.

The distance between the pair of bearing mechanisms 74,
That is, the width of the end portion on the unloading side of the run-up conveyor 60 is set so that it can enter the inside of the pair of bearing mechanisms 41a on the side of the weighing conveyor 22, as shown in FIGS.

A screw support plate 77 bent in an inverted L shape is fixed to the outside of the lower portion of the other side (delivery side) of the side plates 69. A tension adjusting screw 78 is attached to the horizontal portion 77a of the screw support plate 77 so as to penetrate therethrough, and a vertical shaft groove 79 is formed upward from the lower end of the vertical portion 77b of the screw support plate 77. Has been done.

An intermediate roller 80 having a diameter larger than that of the carry-out roller 75 is arranged in parallel with the carry-out roller 75 between the vertical portions 77b of the screw support plates 77. The intermediate roller 80 is
Similar to the intermediate roller 35 of the weighing conveyor 22, the shaft 81 is configured to pass through the center of the bearing mechanism fixed to both ends of the cylindrical body, and the both ends of the shaft 81 form the shaft groove 79 of the screw support plate 77. It passes and is pushed from above by the lower end of the tension adjusting screw 78.

The endless belt-shaped conveyor belt 83 of the run-up conveyor 60 is stretched over so that one surface thereof is in contact with the outer circumferences of the carry-in roller 71, the carry-out roller 75 and the intermediate roller 80.

A drive belt 84 is stretched between the carry-in roller 71 and the pulley 65 of the drive motor 64. The drive motor 64 drives the transport belt 83 to transport from the carry-in roller 71 side to the carry-out roller 75 side at substantially the same speed as the transport belt 56 of the weighing conveyor 22.

The carry-out roller 75 of this run-up conveyor 60
2 and 3, as shown in FIG. 2 and FIG. 3, close to the carry-in roller 42 of the weighing conveyor 22 so that the gap is minimized (for example, 1 mm) in a range where the conveyor belts 56 and 83 do not contact each other. There is. Therefore, even if the thickness of the conveyor belt is taken into consideration, the length of the depressed portion of the gap between the conveyors is 10 mm or less, and an article having a length of about 20 mm is not affected by the gap between the conveyors, and the run-up conveyor 60 Can be smoothly transferred to the weighing conveyor 22.

The run-up conveyor 60 has side plates 38
By loosening the bolt 67 that holds the feed roller 75 and pulling up the carry-out roller 75 side upward, the distance between the pulley 65 and the carry-in roller 71 is shortened, and the drive belt 84 can be removed from the pulley 65. If removed, the transport mechanism portion can be removed from the second support plate 66, and maintenance can be easily performed.

Further, the sorting conveyor 90 arranged on the carry-out side of the weighing conveyor 22 is constructed substantially symmetrically with the running conveyor 60 except that the conveyor length is short.

Therefore, the detailed structure of the sorting conveyor 90 is the same as that of the run-up conveyor 60, and only the essential parts will be described below with reference to FIG.

The sorting conveyor 90 is supported above the base 21 via a support member 91 fixed on the base 21, a drive motor 92 is fixed to the support member 91, and a drive motor 92 is attached to the drive motor 92. A pulley 93 is attached.

A pair of bearing mechanisms 94 (see FIG. 3) are attached to one end side (carry-in side) of the support member 91 so as to face each other. Carry-in roller 95 with the same diameter
Both ends of the are rotatably supported.

Below the carry-in roller 95, an intermediate roller 96 is provided.
Is arranged. The intermediate roller 96 is provided with a tension adjusting mechanism (not shown).

On the other end side (carry-out side) of the support member 91, a carry-out roller 97 is rotatably supported, and one end of the conveyor belt 98 formed in an endless belt shape is carried in by the carry-in roller 9.
5, the intermediate roller 96 and the carry-out roller 97 are wound so as to come into contact with the outer peripheries thereof.

A drive belt 99 is stretched between the carry-out roller 97 and the pulley 93 of the drive motor 92. The drive motor 92 drives the conveyor belt 98 to be equal to or faster than the conveyor belt 56 of the weighing conveyor 22.

The carry-in roller 95 of the sorting conveyor 90
Also, they are close to the carry-out roller 52 of the weighing conveyor 22 so as to be the minimum (for example, 1 mm) in a range where the gaps between the conveyor belts 56 and 98 do not contact each other. For this reason, even if the thickness of the conveyor belt is taken into consideration, the length of the depressed portion of the gap between the conveyors is 10 mm or less, and articles of about 20 mm can be smoothly transferred from the weighing conveyor 22 to the sorting conveyor 90.

The run-up conveyor 60 and the weighing conveyor 2
A sensor 100 for detecting the timing of loading the article onto the weighing conveyor 20 is provided above the space between the two. The sensor 100 is composed of, for example, a plurality of reflection type light-emitters arranged in a direction orthogonal to the carrying-in direction of the article, and applies light from above to the packaging bag of the article which is transferred from the run-up conveyor 60 to the weighing conveyor 22 and reflects it. Upon receiving the light, it is detected that the article is carried in.

Further, the sorting conveyor 90 is provided with an excluding device 101 for excluding, from the sorting conveyor 90, defective products whose weight measured by the weighing machine is not within the preset range. When the defective product is conveyed to a predetermined position, the removing device 101 ejects the defective product from the sorting conveyor 90 by jetting air from the side, for example.

In the sorting machine thus constructed, for example, a child bag packaged article having a length of about 20 mm is carried from the packaging line onto the run-up conveyor 60 at a predetermined interval (almost equal to the transport length of the weighing conveyor 22). Then, as shown in FIG. 11, each article W is conveyed toward the weighing conveyor 22 and transferred to the weighing conveyor 22. At this time, the run-up conveyor 6
Since the length of the depressed portion between 0 and the weighing conveyor 22 is shorter than the length of the article as described above, the article W smoothly moves onto the weighing conveyor 22 and a predetermined time from the carry-in timing detected by the sensor 100 ( The weight of the article W is detected based on the weighing signal at the timing when the time until the weighing signal stabilizes), and it is determined whether the weight is within the set range.

The determination result is sent to the excluding device 101 of the sorting conveyor 90, and when the article weighed on the weighing conveyor 22 moves to a predetermined position of the sorting conveyor 90, it is sorted according to the determination result. . Since the gap between the weighing conveyor 22 and the sorting conveyor 90 is also small with respect to the length of the article, the impact on the weighing device 23 of the weighing conveyor 22 due to the shock when the article is transferred from the weighing conveyor 22 to the sorting conveyor 90 is small. As a result, the timing of carrying out the article from the weighing conveyor 22 and the timing of carrying in the next article can be set almost at the same time, and the weighing efficiency can be improved.

Further, in each conveyor, since the conveyor belt is hung from the small-diameter roller to the large-diameter roller therebelow in a substantially vertical direction, it is not necessary to apply an unreasonable bending force to the conveyor belt by the small-diameter roller. In addition, the belt life is extended, strong curving is not provided, and the conveyance speed is uniform.

Further, in the measuring conveyor 22, since the intermediate roller 35 is provided at a position higher than the first and second rollers, it is necessary to increase the contact angle between the first and second rollers 48 and 53 and the conveyor belt 56. Therefore, the rotational force can be efficiently transmitted to the conveyor belt 56.

In addition, the intermediate roller 35 is a conveyor belt 56.
Since it is in contact with the surface opposite to the other rollers, the curving habit during the operation stop period is corrected by the intermediate roller 35 that gives a force in the direction opposite to the habit, and unevenness in the conveyance speed does not occur, High weighing accuracy.

Further, the carry-in roller 42 of the weighing conveyor 22
The carry-out roller 52 supports both ends of the carry-out roller 52 from the outside by the bearing mechanisms 41a and 51a, and the carry-out side end of the run-up conveyor 60 and the carry-in side end of the sorting conveyor 90 enter the inside of the bearing mechanisms 41a and 51a. Therefore, the gap between the conveyors can be reduced, and the bearing mechanisms 41a and 51a having a large diameter can be used, so that the deterioration of the weighing accuracy due to the uneven rotation can be prevented.

Further, although the above embodiment is an example in which the present invention is applied to a weight sorter, the present invention can be similarly applied to an apparatus which does not have a sorting function and simply outputs a weighing result.

In the above embodiment, the weighing conveyor 2
Although the second carry-out roller 52 has the same diameter as the carry-in roller 42, for example, when the measured articles are dropped from the carry-out side of the weighing conveyor 22 for processing, the carry-out roller does not need to have a small diameter. The diameters of the first and second rollers 48 and 53 may be the same.

[0063]

As described above, in the carrying and weighing device of the present invention, the carry-in roller of the carrying section of the measuring conveyor is made small in diameter, and the carry belt is stretched from the carry-in roller to the large first roller below. Therefore, even if a carry-in roller with a small diameter is used, the conveyor belt is not overpowered, the belt life can be extended, strong bending is not applied, and the conveyor speed does not become uneven. Does not fall.

In addition, the second roller disposed below the carry-out roller
An intermediate roller is arranged between the roller and the first roller at a position higher than the first and second rollers, and one side of the conveyor belt is in contact with the outer circumference of the carry-in roller, the carry-out roller and the first and second rollers, and the other surface is intermediate. Since the rollers are bridged so as to be in contact with the outer circumference of the roller, the contact angle between the conveyor belt and the first and second rollers can be made large, and the rotational force of the rotation drive device can be efficiently transmitted to the conveyor belt.

Further, since the carry-out roller of the run-up conveyor has a diameter substantially the same as that of the carry-in roller of the metering conveyor and are brought close to each other, even small articles can be smoothly transferred from the run-up conveyor to the conveyor section of the metering conveyor. Weighing accuracy does not deteriorate due to changes in posture.
