Description

Automatic feeder with drop impact buffer cover {AUTO FEEDER WITH BUFFER COVER}

electronic checkweigher

Republic of Korea Patent Registration No. 10-1778844 (electronic checkweigher without sensor conveyor)

An object of the present invention is to provide a checkweigher equipped with an automatic feeding device including a drop impact buffer cover in order to improve structural instability of sorted products placed on a weighing plate.

In the cited patent registered by the present applicant, partitions 110 are formed at regular intervals on the supply conveyor 10, and sorted items are automatically or manually put into each partition, and the moment the conveyor belt 100 stops while being transported The rod of the air cylinder 20 entering the metering unit moves forward and pushes the sorted product to the metering panel 31 of the metering unit 30, and after the weight is measured in the metering panel 31, the air cylinder enters the discharge conveyor. It is a sorter that is pushed and discharged by the conveyor belt 100 of the discharge conveyor 50 by 40, but this configuration has the following problems that are difficult to use industrially.

1) When the metering plate 31 is almost level with the conveyor belt 100, even though the metering plate 31 has a downwardly inclined end at the entrance where the sorted goods enter, the sorted goods It was difficult to land due to collision, and when the metering panel 31 was installed low enough, it took time for the vibration of the metering panel 31 to stabilize due to the impact of the landing sorted item, so there was a problem in that the processing speed was reduced.

That is, it is difficult to optimize the appropriate heights of the metering plate 31 and the conveyor belt 100 .

2) There was a problem in that the sorted product could not be accurately dropped to the center of the weighing plate 31. When the rod of the metering part entry air cylinder 20 pushes the pushing plate 140 at a low speed, the sorted goods propagate while leaning on the pushing plate 140, so it cannot reach the central part, and if it is pushed at a high speed, the part hit Various movement results were derived, but it was difficult to settle in the central part, and this problem led to undesirable results in accurately measuring the sorted items.

That is, there was a problem in that it was difficult to seat the sorted product at the center of the weighing plate 31 for accurate measurement.

3) On the other hand, when the sorted product placed on the upper surface of the conveyor belt 100 of the supply conveyor 10 is fish such as croaker or thin belt, when the rod advances the pushing plate 140, it is like a fin or a tail part Thin fish caught in the gap between the upper surface of the conveyor belt 100 and the push plate 140, making it difficult to transport and frequently damaging the fish body, and when the sorted item was shellfish such as abalone or individual oysters, the conveyor belt ( 100) was frequently damaged, such as tearing.

That is, there was a problem in that the conditions for transferring the sorted articles from the upper surface of the conveyor belt 100 to the measuring plate 31 were not consistent.

4) In the cited patent, since the supply conveyor 10 needs to be a system that repeats operation, stopping for a while, and then operating again, the drive unit of the supply conveyor 10 must use an expensive servo motor or index motor. and a drive is required to control it. If it could be operated at constant speed, it would have been possible to apply a more economical general induction motor.

That is, the cited patent had a problem in that it was difficult to manufacture at low cost.

In order to solve these problems, the present invention has been made,

The present invention is characterized by having a cover having a curved surface formed while following the trajectory of the rotation radius of the head pulley 130 while being spaced apart from the head pulley 130 of the supply conveyor 10 by a predetermined distance.

In addition, the drop impact buffer cover provided by the present invention is characterized in that it enables an automatic feeding device in a checkweigher for aquatic products such as fish or shellfish.

The present invention minimizes the impact applied to the metering plate to give a sense of structural stability, thereby enabling accurate measurement.

The present invention compensates for the disadvantages of the conventional method in which fish or shellfish are transported while being pushed on the upper surface of the conveyor belt 100 and land on the weighing plate 31, thereby protecting the device and minimizing damage to the body of the fish.

The present invention compensates for the disadvantages that have not been automated in aquatic product checkweighers such as fish and shellfish, enabling a semi-automatic or fully automatic feeding device, so that breakthrough effects such as productivity improvement and labor cost savings can be expected.

That is, the sorting articles 300 are rolled or overturned and buffered, reaching just before the weighing plate 31 in FIG. 7 and then, when put into the weighing plate 31, there is no or minimal impact load. As such, it can be placed on the central portion of the metering plate 31 when spraying.

In the present invention, the curved portion 420 is shown and described in a semi-cylindrical shape, but the curved portion 420 may be formed in a polygonal shape, or may be configured to be arranged by bending a plurality of round bars. In addition to this, the present invention If the technology pursued by , that is, the cover that the sorted article 300 stored between the partitions 110 is buffered without leaving the inside of the curved portion 420 and reaches just before the metering plate 31, all of them fall under the right. something to do.

5 to 7 are views when the sorted product 300 is pushed in the "W" direction, which is the transverse direction of the supply conveyor 10,

8 to 11 are the longitudinal (縱) direction of the supply conveyor 10 to the sorted article 300 This is a drawing when pushing in the "L" direction.

In the present invention, the weighing unit 30 includes a weighing plate 31, a load cell 32 (Load-cell) fixedly coupled to the lower portion of the weighing plate 31, and a load cell on which the fixed part of the load cell 32 is placed and placed. 32) It consists of a pedestal 33 for coupling the whole to the frame 80 or leg 90, and is fixedly coupled to the frame 80 or leg 90 or one side of the pedestal 33, and the sorted article 300 ) It is composed of a discharge conveyor entry air cylinder 40 for pushing, and a pushing plate 140 is provided at the end of the rod of the discharge conveyor entry air cylinder 40.

At this time, the present invention provides another embodiment of the metering unit 30.

The metering unit 30 includes a metering plate 31 as described above, and an air cylinder 40 entering the discharge conveyor for pushing the sorted articles 300 weighed on the metering panel 31 toward the discharge conveyor 50. ), but is not limited thereto.

As shown in FIG. 11, the metering unit 30 omits the metering plate 31 and the air cylinder 40 entering the discharge conveyor, and is a sensor conveyor 1000 having a belt surface running in an endless track, and the sorted product 300 By measuring the weight of and driving the conveyor after measuring, the sorted items 300 that have been weighed can be transported toward the discharge conveyor 50. Since the sensor conveyor 1000 that measures this weight is a known technology, more detailed No explanation.

The sensor conveyor 1000 may be provided with guides 1100 on three sides excluding the discharge portion for stable landing and storage of the sorted articles 300 .

On the other hand, as shown in FIG. 16

The supply conveyor 10,

Adding a vibrating means 500 and further comprising a rotating body 900 rotating in the "R" direction for suppressing and releasing the two-layer structure of the sorting article 300 at a position before the sorting article 300 is discharged. can be characterized

The entire frame 80 including the supply conveyor 10 is vibrated by the vibrating means 500 using a pair of vibrating motors obliquely disposed outside the frame 80 of the supply conveyor 10, and the vibration Vibration feeder having a buffer member 700 so that it is not transmitted to the outside, a saddle 600 fixedly coupled to the frame 80 at the top of the buffer member 700, and a separate bottom frame 800 at the bottom. As a form, this is a well-known technology, so a more detailed description is omitted.

When the vibration as described above is transmitted to the supply conveyor 10, the sorted articles 300 stored between the partitions 110 become a structure suitable for easily storing and arranging one (or more) items in each partition. At this time, When two or more are to be accommodated in one compartment to form a double layer, the two-layer structure can be suppressed and released by the rotating body 900 rotating in the "R" direction, and this rotating body is also widely used in the industry. Since it is technical, a detailed description is omitted.
