Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technique for accurately weighing small articles in a transport weighing device that weighs articles while transporting them.
[0002]
[Prior art]
For example, in a line where candy and other confectionery are wrapped in child bags one by one, the wrapping process may contain only products that are not properly stored in the bag, such as empty or missing confections. Items that are connected or that are connected due to poor cutting between bags.
[0003]
In order to find such an article and remove it from the line, as shown in FIG. 12 (a), an article W carried out from the run-up conveyor 1 is received by the transport section 6 of the weighing conveyor 5, and the weight of the article is reduced. It is conceivable to use a transport weighing device that is configured to measure by the weighing device 7 during transport.
[0004]
However, such a conventional transport and weighing device has rollers 3a and 3b for feeding the transport belt 2 of the run-up conveyor 1 and rollers 6b and 6c for transporting the transport belt 6a of the transport section 6 of the weighing conveyor 5. However, since the small article W is several tens of millimeters or more, 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 move smoothly.
[0005]
As a method for solving this, as shown in FIG. 12B, a transfer plate 8 may be provided in a gap between the run-up conveyor 1 and the weighing conveyor 5 so that articles do not fall between the conveyors. Conceivable. However, since the passing plate 8 merely slides the article and has no force to convey the article by itself, if the tip of the bag enters the gap between the passing plate 8 and the conveyer 1, the biting occurs, and the passing plate 8 comes off. And the flow of subsequent articles is greatly disturbed. In addition, even if the transfer speed of the articles on the transfer plate 8 is greatly reduced, and the articles are transferred onto the weighing conveyor 5, the shock due to the difference in speed does not stabilize the posture of the articles on the weighing conveyor, and the weighing is performed. There is a problem that an error occurs.
[0006]
Further, as another solution, it is conceivable to reduce the diameter of the rollers of the run-up conveyor 1 and the rollers of the weighing conveyor 5 to, for example, 10 mm or less so as to reduce the length of the recessed portion of the gap between the conveyors.
[0007]
[Problems to be solved by the invention]
However, if the roller diameter of the run-up conveyor and the weighing conveyor is reduced to 10 mm or less, the radius of curvature of the return portion of the belt is reduced, so that the belt is forcibly shortened and its life is shortened. There is a problem in that the transfer speed becomes uneven, the transport speed becomes uneven, and the weighing accuracy is significantly reduced.
[0008]
The present invention solves this problem, so that even small articles can be smoothly transferred from the run-up conveyer to the weighing conveyer, and accurate weighing can be performed without exerting excessive force on the belt and causing uneven conveyance speed. It is an object of the present invention to provide a transfer weighing device.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram schematically showing an entire sorting machine to which a transport weighing device according to an embodiment is applied, and FIGS. 2 to 10 show the structure of each conveyor.
[0011]
This sorter is a small article, such as a confectionery packaged in small bags one by one by a packaging machine (not shown), in which the contents are empty, or in which only a part of the missing confectionery is contained, or It is configured such that the connected bags and the like can be excluded from the line. As shown in FIG. 1, a weighing conveyor 22 is disposed at the center of the base 21, and a package is provided at one end of the base 21. A run-up conveyer 60 for carrying articles received from the machine (not shown) to the weighing conveyor 22 is arranged. On the other end side of the base 21, the articles weighed by the weighing conveyor 22 are received. Is disposed as it is, and a sorting conveyor 90 for removing defective products from the transport path is provided.
[0012]
The weighing device 23 of the weighing conveyor 22 has four shafts 23a for receiving a load, and outputs a signal corresponding to the weight applied to the shaft 23a.
[0013]
As shown in FIGS. 2 to 5, the transport section of the weighing conveyor 22 is supported by a pair of support plates 25 facing each other. The two support plates 25 include a horizontally long rectangular fixing portion 25a, a connecting portion 25b extending upward from one end of the fixing portion 25a, and a supporting portion extending horizontally from an upper end of the connecting portion 25b in a direction opposite to the fixing portion 25a. 25c, the outer shape is formed in a substantially crank shape. The two support plates 25 are connected in parallel to each other by two prismatic shafts 27 fixed at both ends by bolts 26 so as to bridge between the lower ends of the fixing portions 25a. The tips of the four shafts 23 a of the measuring device 23 are fixed by nuts 28.
[0014]
Between the connecting portions 25b of the two support plates 25, a horizontally long rectangular middle plate 29 is vertically laid horizontally, and a motor support plate 30 is erected on one surface 29a side of the middle plate 29, and a motor support plate is provided. A drive motor 31 is supported on 30. A pulley 32 is fixed to a shaft 31 a of the drive motor 31.
[0015]
The support portion 25c of each of the support plates 25 is bent so that the upper portion thereof is located inside the lower portion, and a side plate 38 described later is fixed to the support portion 25c at the upper edge at one end (loading side) of the upper portion. A U-shaped groove 33 is provided. Further, both ends of a shaft 36 of the intermediate roller 35 are fixed to nuts 37 on the other end side (unloading side) of the upper portions of both support portions 25c.
[0016]
As shown in FIG. 6A, the intermediate roller 35 has a bearing mechanism 35b fixed to both ends of a hollow cylindrical body 35a, and the cylindrical body 35a rotates around a shaft 36 inscribed in the bearing mechanism 35b. Is configured.
[0017]
Inside the upper portions of the support portions 25c, a pair of horizontally long rectangular side plates 38 are fixed by bolts 39 tightened so as to pass through the grooves 33 of the support portion 25c.
[0018]
The side plates 38 are connected by an underlay plate 40 horizontally laid on the inside of the upper end. The underlay plate 40 is for supporting a load of an article conveyed by the conveyor belt 56 described below from below to prevent the conveyor belt 56 from hanging down.
[0019]
A bearing body 41 is laid on the inside of the upper part on one end side (loading side) of the both side plates 38. At both ends of the bearing body 41, large-diameter bearing mechanisms 41a are provided so as to face each other.
[0020]
A small-diameter (for example, 6 mm in diameter) carry-in roller 42 whose diameter is shorter than half the article length is rotatably supported by both bearing mechanisms 41a. As shown in FIG. 6B, the carry-in roller 42 is supported such that outer peripheries of both ends thereof are in contact with the inner perimeter of the large-diameter bearing mechanism 41a.
[0021]
A screw support plate 43 bent in an inverted L-shape is fixed to the outside of the lower portion on one end side (loading side) of 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 penetrate vertically, and a vertically long shaft groove 46 is formed in the vertical portion 43b of the screw support plate 43 from the lower end upward. It is formed toward.
[0022]
A first roller 48 having a larger diameter (for example, a diameter of 20 mm) than the carry-in roller 42 is arranged between the vertical portions 43b of the two screw support plates 43 in parallel with the carry-in roller 42. In the first roller 48, similarly to the intermediate roller 35 shown in FIG. 6A, a bearing mechanism is fixed to both ends of a hollow cylindrical body, and the cylindrical body rotates about a shaft 49 inscribed in the bearing mechanism. It is configured as follows.
[0023]
Both ends of the shaft 49 of the first roller 48 pass through the shaft groove 46 of the screw support plate 43 and are pushed from above by the lower end of the tension adjusting screw 45.
[0024]
On the other hand, a bearing body 51 identical to the bearing body 41 is also horizontally laid at the same height and parallel to the other end side (unloading side) of the both side plates 38. At both ends of the bearing body 51, large-diameter bearing mechanisms 51a are provided so as to face each other. Both ends of a carry-out roller 52 having the same diameter as the carry-in roller 42 are rotatably supported by both bearing mechanisms 51a. Have been.
[0025]
Below the discharge roller 52, a second roller 53 is disposed 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, has a shaft 54 inscribed in a bearing mechanism fixed to both ends of a hollow cylindrical body. It has a structure that rotates around the center. Both ends of the shaft 54 of the second roller 53 are fixed to the side plate 38 by nuts 55.
[0026]
The conveyor belt 56 of the weighing conveyor 22 is formed in an endless belt shape, one surface of which is in contact with the outer periphery 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 surface is provided. It is stretched between the first and second rollers 48 and 53 so as to be in contact with the outer periphery of the intermediate roller 35. The transport belt 56 is given an appropriate tension by adjusting the tension adjusting screw 45.
[0027]
A drive belt 57 is stretched between the second roller 53 and the pulley 32 of the drive motor 31. The drive motor 31 rotationally drives the second roller 53 at a constant speed such that the transport belt 56 is transported from the carry-in roller 42 side to the carry-out roller 52 side.
[0028]
In the weighing conveyor 22 having such a transport section, the transport belt 56 is hung substantially vertically from the carry-in roller 42 and the carry-out roller 52 toward the first and second rollers 48, 53 located almost directly below the transport belt 56, respectively. Even if the diameters of the carry-in roller 42 and the carry-out roller 53 are small, an excessive bending force is not applied to the transport belt 56, and a strong curve is not applied during the operation stop period.
[0029]
In addition, 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 torque of the second roller 53 can be efficiently transmitted.
[0030]
Further, since the intermediate roller 35 is in contact with the surface of the conveyance belt 56 opposite to the other roller, the intermediate roller 35 applies a force in a direction to correct the bending of the conveyance belt by the other roller during the operation stop period during driving. Because of this, unevenness in the transport speed is not caused.
[0031]
In addition, when the measuring conveyor 22 loosens the bolt 39 holding the side plate 38 and pulls the carry-in roller 42 side upward about the shaft 36 of the intermediate roller 35, the pulley 32 and the second roller 53 The distance becomes shorter, the drive belt 57 can be removed, and if the drive belt 57 is removed, the transport mechanism portion except for the intermediate roller 35 can be removed from the support plate 25, and maintenance can be performed easily.
[0032]
On the other hand, as shown in FIGS. 1 and 7 to 10, the run-up conveyer 60 disposed on the loading side of the weighing conveyer 22 is supported via a pair of support plates 61 whose lower portions are fixed on the base 21. It is supported above the table 21.
[0033]
Inside the two support plates 61, a stepped middle plate 62 is laid horizontally. A motor support plate 63 is attached to a low step portion of the middle plate 62, and a drive motor is mounted on the motor support plate 63. 64 is fixed. A pulley 65 is attached to a shaft 64a of the drive motor 64.
[0034]
Second support plates 66 are fixed to the upper portions of both support plates 61 so as to face each other. The second support plate 66 is bent so that its upper part is located inside the lower part, and a U-shaped groove 68 for fixing a side plate 69 to be described later with a bolt 67 is formed at the upper edge of the upper part. And at the center.
[0035]
A pair of side plates 69 are disposed inside the second support plate 66 so as to face each other, and the both side plates 69 are connected by an underlay plate 70 horizontally laid between upper ends thereof. The underlay plate 70 receives the load of the articles conveyed by the conveyor belt 83 described later and prevents the conveyor belt 83 from hanging down.
[0036]
A carry-in roller 71 is rotatably supported at one end side (a carry-in side) of both side plates 69. Like 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 a bearing mechanism fixed to both ends of the cylindrical body. It is fixed to the side plate 69 by 73.
[0037]
A pair of bearing mechanisms 74 are attached to the other end side (unloading side) of the underlay plate 70 so as to face each other. Both ends of a discharge 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 diameter of the bearing mechanism 74 is smaller than the diameter of the bearing mechanism 41 a supporting the carry-in roller 42 of the weighing conveyor 22.
[0038]
Further, the interval between the pair of bearing mechanisms 74, that is, the width of the unloading side end of the run-up conveyer 60, can enter the inside of the pair of bearing mechanisms 41a on the weighing conveyer 22 side, as shown in FIGS. Is set to
[0039]
A screw support plate 77 bent in an inverted L-shape is fixed to the outside of the lower end on the other end side (unloading side) of both 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 vertically long axial groove 79 is formed in the vertical portion 77b of the screw support plate 77 from the lower end upward. Have been.
[0040]
Between the vertical portions 77b of the two screw support plates 77, an intermediate roller 80 having a larger diameter than the discharge roller 75 is disposed in parallel with the discharge roller 75. Like the intermediate roller 35 of the weighing conveyor 22, the intermediate roller 80 is configured such that the shaft 81 passes through the center of a bearing mechanism fixed to both ends of the cylindrical body. , And is pushed from above by the lower end of the tension adjusting screw 78.
[0041]
The transport belt 83 formed in an endless belt shape of the run-up conveyor 60 is stretched so that one surface thereof is in contact with the outer periphery of the carry-in roller 71, the carry-out roller 75, and the intermediate roller 80.
[0042]
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 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.
[0043]
As shown in FIGS. 2 and 3, the carry-out roller 75 of the run-up conveyor 60 has a minimum gap (for example, 1 mm) with respect to the carry-in roller 42 of the weighing conveyor 22 within a range where the conveying belts 56 and 83 do not contact each other. ). For this reason, even when the thickness of the conveyor belt is taken into consideration, the length of the recessed portion of the gap between the conveyors is 10 mm or less, and articles having a length of about 20 mm are not affected by the gap between the conveyors, From the weighing conveyer 22 to the weighing conveyor 22.
[0044]
When the bolt 67 holding the side plate 38 is loosened and the carry-out roller 75 side is pulled upward, the distance between the pulley 65 and the carry-in roller 71 is shortened. If the drive belt 84 is removed, the transport mechanism can be removed from the second support plate 66, and maintenance can be easily performed.
[0045]
In addition, the sorting conveyor 90 arranged on the unloading side of the weighing conveyor 22 is configured substantially symmetrically with the run-up conveyor 60 except that the conveyor length is short.
[0046]
Therefore, the detailed structure of the sorting conveyor 90 is the same as that of the run-up conveyor 60, and only the main parts will be described below with reference to FIG.
[0047]
The sorting conveyor 90 is supported above the base 21 via a support member 91 fixed on the base 21, and a drive motor 92 is fixed to the support member 91, and a pulley 93 is mounted on the drive motor 92. Installed.
[0048]
A pair of bearing mechanisms 94 (see FIG. 3) are attached to one end side (loading side) of the support member 91 so as to face each other. The bearing mechanism 94 has the same diameter as the unloading roller 52 of the weighing conveyor 22. Both ends of the carry-in roller 95 are rotatably supported.
[0049]
An intermediate roller 96 is disposed below the carry-in roller 95. The intermediate roller 96 is provided with a tension adjusting mechanism (not shown).
[0050]
An unloading roller 97 is rotatably supported on the other end side (unloading side) of the support member 91, and one end of the transport belt 98 formed in an endless belt shape has an import roller 95, an intermediate roller 96, and an unloading roller. It is laid so as to be in contact with the outer periphery of the roller 97.
[0051]
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 transport belt 98 to transport at a speed equal to or higher than the transport belt 56 of the weighing conveyor 22.
[0052]
The carry-in roller 95 of the sorting conveyor 90 is also close to the carry-out roller 52 of the weighing conveyor 22 so as to be minimum (for example, 1 mm) within a range where the gap between the conveying belts 56 and 98 does not contact. For this reason, even when the thickness of the conveyor belt is taken into consideration, the length of the recessed portion of the gap between the conveyors becomes 10 mm or less, and articles of about 20 mm can be smoothly transferred from the weighing conveyor 22 to the sorting conveyor 90.
[0053]
In addition, a sensor 100 for detecting a timing at which articles are loaded into the weighing conveyor 20 is provided above the running conveyor 60 and the weighing conveyor 22. The sensor 100 includes, for example, a plurality of reflection-type light emitting and receiving devices arranged in a direction orthogonal to the direction in which the articles are carried in. Receiving the light, it detects the loading of the article.
[0054]
Further, the sorting conveyor 90 is provided with an elimination device 101 for eliminating defective products whose weight measured by the weighing machine is not within a preset range from the sorting conveyor 90. When the defective product is transported to a predetermined position, the removing device 101 ejects the defective product from the sorting conveyor 90 by, for example, injecting air from the side.
[0055]
In the sorting machine configured as described above, for example, when a child bag packaged article having a length of about 20 mm is loaded from the packaging line onto the run-up conveyor 60 at a predetermined interval (an interval substantially equal to the transport length of the weighing conveyor 22), As shown in FIG. 11, each article W is conveyed toward the weighing conveyor 22 and transfers to the weighing conveyor 22. At this time, since the length of the drop portion between the run-up conveyor 60 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 is carried in by the sensor 100. The weight of the article W is detected based on the weighing signal at a timing when a predetermined time (time until the weighing signal stabilizes) from the timing, and it is determined whether or not the weight is within a set range.
[0056]
The determination result is sent to the elimination device 101 of the sorting conveyor 90, and when the articles weighed on the weighing conveyor 22 have moved to a predetermined position on the sorting conveyor 90, the items are sorted based on the determination result. In addition, since the gap between the weighing conveyor 22 and the sorting conveyor 90 is also smaller than the article length, the impact of the shock when the articles transfer from the weighing conveyor 22 to the sorting conveyor 90 on the weighing device 23 of the weighing conveyor 22 is small. In addition, it is possible to make the timing at which the articles are unloaded from the weighing conveyor 22 and the timing at which the next article is loaded at substantially the same time, thereby improving the weighing efficiency.
[0057]
In addition, in each conveyor, the conveyor belt is stretched from the small-diameter roller to the large-diameter roller under the conveyor in a substantially vertical direction. Becomes longer, a strong bend is not formed, and unevenness in the transport speed does not occur.
[0058]
Further, in the weighing conveyor 22, 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 transport belt 56 can be increased, The rotational force can be efficiently transmitted to the transport belt 56.
[0059]
Further, since the intermediate roller 35 is in contact with the surface of the conveyor belt 56 opposite to the other roller, the curving formed during the operation stop period is corrected by the intermediate roller 35 that applies a force in the opposite direction to the curl. The measurement accuracy is high without causing irregularities in the transport speed.
[0060]
The carry-in roller 42 and the carry-out roller 52 of the weighing conveyor 22 have both ends supported by bearing mechanisms 41a and 51a from outside, and the carry-out side end of the run-up conveyor 60 and the sorting conveyor 90 are provided inside the bearing mechanisms 41a and 51a. Is designed to allow the carry-in side end to enter, so that the gap between the conveyors can be reduced, and large-diameter bearing mechanisms 41a and 51a can be used, thereby preventing deterioration of weighing accuracy due to uneven rotation. be able to.
[0061]
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 having no sorting function and simply outputting a weighing result.
[0062]
In the above-described embodiment, the discharge roller 52 of the weighing conveyor 22 has the same diameter as the carry-in roller 42. For example, when the weighed articles are dropped from the discharge side of the weighing conveyor 22 for processing, the discharge roller 52 is used. Need not be small, and may be the same diameter as the first and second rollers 48 and 53.
[0063]
【The invention's effect】
As described above, the transport weighing device of the present invention reduces the diameter of the carry-in roller of the transport section of the weighing conveyor, and extends the transport belt from the carry-in roller to the lower large first roller. Even if the carry-in roller is used, the transport belt is not overloaded and the life of the belt can be extended. Also, since there is no strong bending and no uneven transport speed, the weighing accuracy does not decrease.
[0064]
Also, an intermediate roller is disposed at a position higher than the first and second rollers between the second roller and the first roller disposed below the discharge roller, and one surface side of the transport belt is a load roller, a discharge roller, and a first roller. Since the belt is in contact with the outer periphery of the second roller and the opposite surface is in contact with the outer periphery of the intermediate roller, the contact angle between the transport belt and the first and second rollers can be increased, and the rotational force of the rotary drive device can be increased. Can be efficiently transmitted to the transport belt.
[0065]
In addition, the unloading rollers of the run-up conveyor are almost the same diameter as the carry-in rollers of the weighing conveyor, so that they are close to each other. Also, the measurement accuracy does not decrease due to the above factors.
