Field of the Invention The present invention relates to an automatic weighing and packaging apparatus for a shot ball, and more particularly, to a short ball automatic weighing and packaging apparatus for improving the reliability of a product by accurately weighing and compacting a shot ball, will be.

Generally, surface machining refers to machining. The concept of negotiation is elimination of unnecessary parts or removal machining to obtain the intended surface.

In particular, surface grinding smoothes the surface of a solid by rubbing it with the edge or surface of another solid. It removes the coating of the surface, the oxide film (rust) and the grit (sand) As well as the process used.

Examples of such polishing include Abrasive Blasting, Grinding, Polishing, and Buffing.

Spray polishing is widely used for construction of piers and buildings, shipbuilding and repair, casting, and surface treatment of metals. In addition to increasing the strength of metals using chilled iron and steel shot abrasives, And it is used in pretreatment and leading paint by methods such as Air Blast Equipment, High Speed Impeller and Wet Blast Technique.

Grinding grinding is a method of grinding a metal surface by sanding an abrasive of a desired size into an air grinder. In order to remove defects of important surface during grinding of coarse parts of forging and casting when removing injection holes, .

Finishing grinding is mainly used to attach abrasive to a belt or a disk grindstone. It is mainly used to remove scratches on the surface of a material by means of tools, to polish the material to a thickness of 0.1 mm, and to remove the coating film during machine assembly or painting.

Buffing is a method of sewing cotton or wool to make it look like a grinding wheel or leather (buff), then applying abrasive around the grinding wheel, pressing the material against the rotating grinding wheel, rubbing the rough surface to polish the surface, Feature.

In recent years, in order to increase the durability of the mechanical parts, various materials have been diversified and advanced, and various special processing methods such as mechanical special processing, electrical special processing and chemical special processing have been studied extensively. In the mechanical special processing, Sandblasting and shot peening can be used to improve the fatigue strength and surface hardness by causing hardening.

Particularly, shot peening can improve the strength of materials to improve the design capability, and it can maintain high toughness at the center of the material, which is very useful for improving the parts of mechanical structure subjected to fatigue load.

The abrasive (Stainless Shot, Cut Wire, Rounded Cut Wire, Zinc Shot, Aluminum Oxide & Garnet, Carbon Steel Shot & Grit) which is the key element of such shot peening needs to increase the production efficiency to meet the demands of various customers. Since the packaging process of the product is not automated, the worker directly measures and packs the weight (15 ~ 20kg) with the scale.

In this way, as the worker directly handles the packaging process of the product, the weight of the product is not accurate and the complaints and claim elements are inherent. In the case of the product packaging process, the labor cost is increased by one person per line.

In addition, there is a problem that the product quality is lowered due to the influx of foreign substances during the packaging process, and the workers are working in a squat position for a long period of time, resulting in industrial accidents and occupational disease factors, resulting in extremely low productivity of about 20% .

In addition, according to the development of the industry, various types of short ball diameters required in various customers are required to construct a new concept production line in order to meet delivery deadlines. However, due to changes in external environment, such as raw material shrinkage and delivery price cut, Because of the difficulty, it is time to research the technology that can automatically package the shotball accurately.

Prior to describing the present invention, in the past, the process for packaging the shot ball discharged from the steel wire cutting device was not automated, and the worker directly measured the weight by the scale and individually packaged it.

In this case, the weight of the product was often not accurate, and the customer's complaints were inherent. In the case of the product packaging process, one person was required for each line, which resulted in a high labor cost. There were industrial accidents and occupational disease factors to work.

Accordingly, the present invention seeks to propose a short ball automatic weighing and packaging apparatus capable of automatically and precisely weighing a short ball to ensure the reliability of the product.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view according to a preferred embodiment of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is another front view according to a preferred embodiment of the present invention. 1 to 3, a short ball automatic weighing and packing apparatus according to a preferred embodiment of the present invention may include an input unit 100, a metering sensor unit 200, and a packaging unit 300 .

The input unit 100 of the present invention includes a body 110 provided adjacent to an outlet 1100 of a steel wire cutting apparatus 1000 for cutting a steel wire to form and discharge a short ball to receive a shot ball, And an opening / closing plate 120 installed at a lower portion of the opening / closing plate 120 so as not to discharge or discharge the shot ball.

4 is a schematic view of the steel wire cutting apparatus 1000. [ Referring to FIG. 4, it can be seen that a steel wire cutting apparatus 1000 for continuously manufacturing shot balls supplied to a shot ball automatic weighing and packing apparatus of the present invention is shown.

That is, the input unit 100 receives the shot ball from the discharge port 1100 of the steel wire cutting apparatus 1000 shown in FIG. 4 into the body 110 in a natural dropping manner, The opening / closing plate 120 may be opened or closed to prevent the door from being discharged.

The discharge port 1100 of the wire cutting apparatus 1000 is connected to the upper portion of the body 110 fixed by the support stand 130 stably vertically standing from the floor (more preferably, (The upper side of the ball 110 is connected) so that the shot ball does not flow out.

5 is an installation state diagram of a filtration unit 400 according to a preferred embodiment of the present invention. Referring to FIG. 5, the filtering unit 400 is installed on the upper part of the input unit 100 to sort the short balls supplied to the body 110 according to their diameters.

Specifically, the filtration unit 400 is provided to further improve the reliability of the product. The filtration unit 400 may include a filtration member 410 having a filtration net 412 and a rotation axis 420. That is, the filtering unit 410 is installed on the upper part of the charging unit 100 so that only the shot ball of a predetermined size or less is allowed to pass through the discharge hole 1100 of the steel wire cutting apparatus 1000 and supplied to the inside of the body 110 The rotary shaft 420 is fixed to one side of the sieve member 410 and rotatably installed on one side of the sieve unit 100 so as to rotate the sieve member 410 inward and outward of the input unit 100, It is possible to make it possible.

The outer surface of the inner surface of the body 110 may have a straight shaft groove 112 formed along the longitudinal direction of the body 110. The outer surface of the body 110 may include a sieve member 410, The rotating shaft 420 fixed to the rotating shaft 420 is detachably inserted and the position of the filtering member 410 can be changed while rotating the rotating shaft 420 as occasion demands.

5 (a), the filtration member 410 is positioned on the upper portion of the charging unit 100 by the rotation shaft 420, and then the charging unit 100, that is, the other side of the charging unit 100 A protrusion 414 protruding in a size accommodated in the receiving groove 114 on the other side of the filtering member 410 is provided in the receiving groove 114 for restricting the position of the filtering mulching member 410, The injection unit 100 and the filtration unit 400 can be stably fixed.

5 (b), it can be seen that the filtering member 410 is moved to the outside rather than the position corresponding to the input unit 100 by the rotating shaft 420. In this case, It can be seen that the ball is in a rest state in which the automatic weighing and packing apparatus is not used.

In addition, a vacuum pump (not shown) for vacuum-sucking the shot ball that has not passed through the sieve 412 may be installed outside the injection unit 100, which can not pass through the sieve 412 beyond the predetermined size, It is intended to separate the shot ball that has not been introduced into the screen 110 from the screen 412.

(Not shown) is installed on the outer side of the body 110. Vacuum is applied to the pail so that most of the shot balls remaining on the sieve 412 due to failure to pass through the sieve 412 are collected It means that it can be recycled for another purpose.

The metering sensor unit 200 of the present invention is configured to meter a shot ball supplied to the loading unit 100 installed at the lower portion of the loading unit 100.

When the shot ball supplied to the body 110 reaches a preset weight value in the metering sensor unit 200, the opening and closing plate 120 is opened under the control of the control unit and the shot ball is moved to the receiving unit 320 When the supply of the shot ball is completed, the lower hole of the body 110 is closed by the opening / closing plate 120 under the control of the control unit.

In other words, the metering sensor unit 200 continuously measures the weight of the shot ball until a predetermined weight value is reached, and can operate the opening / closing plate 120 to be open when the preset weight value coincides with the predetermined weight value . That is, when the metering sensor unit 200 completes accurate metering of the shot ball, the opening / closing plate 120 installed on the lower part of the body 110 is controlled by the control unit to open the hole in the lower part of the body 110, And is discharged to the receiving unit 320. [ Then, when the discharge of the shot ball is completed, the opening of the lower portion of the body 110 is closed by the opening / closing plate 120 under the control of the control unit.

When the open / close board 120 is closed, the shot ball discharged from the discharge port 1100 of the steel wire cutting apparatus 1000 is continuously supplied to the input unit 100 and the predetermined weight is repeatedly measured.

Here, the metering sensor unit 200 may be installed in the lower part of the charging unit 100 (or inside the body 110 or the opening and closing plate 120), and may be carried out in the form of a load cell. A load cell refers to a transducer that measures force or load by changing physical quantities such as force or load into electrical signals.

In other words, the load cell is deformed by a force or a load in proportion to the strain gauge (= strain, strain gauge), and the strain generated per unit length is called a strain. And it is mainly used in automation processes and the like.

As such a load cell, for example, a hydraulic load cell, a pneumatic load cell, and an electric load cell may be applied.

Hydraulic load cell utilizes the force of weight. When a weight is applied to the outside of the piston installed in the cylinder, a corresponding force is generated and transmitted to the hydraulic oil in a certain container to measure the weight.

A pneumatic load cell uses the same principle as a hydraulic load cell to directly measure the pressure change due to weight by using a flexible diaphragm instead of a piston. The diaphragm is designed to automatically maintain the equilibrium of the force. The diaphragm is supplied with constant pressure air to one side of the diaphragm, and the air is discharged to the outside according to the position of the piston type discharge valve connected to the diaphragm, have.

An electric load cell can be divided into two types: a strain gage cell and an induction cell. A cantilevers load cell using a strain gage is capable of measuring very small weights , And load cells using strain gages can be compressed, elongated, or compounded.

However, since the structure of such a load cell is obvious to those skilled in the art, further explanation will be omitted here.

The packaging unit 300 of the present invention includes a rotary table 310 rotatably installed at a lower portion of the charging unit 100 and a rotary table 310 installed at a predetermined interval on the rotary table 310, And a plurality of receiving units 320 that can be packed in units such that the short balls are supplied.

6 is a plan view of a packaging unit 300 according to a preferred embodiment of the present invention. Referring to FIG. 6, the rotation table 310 is seen from above.

That is, the rotary table 310 is circularly formed with a predetermined diameter and is coupled to be rotated through a central shaft 312 rotated by a power means (for example, a motor). However, a bearing may be provided at a coupling portion with the center shaft 312 in some cases.

The center shaft 312 is supported by the pedestal 314 and is rotated by the power means so that the short ball can be packed in each receiving unit 320 partitioned by the rotating table 310. In addition, an operation panel for turning on / off the power means or adjusting the rotational speed of the power means may be provided.

A replenishing metering tank 140 branched from the outlet 1100 of the steel wire cutting apparatus 1000 and capable of discharging the shot ball to the receiving unit 320 may be installed by a predetermined amount. (See Fig. 3)

Subsequently, an auxiliary load cell 322 for measuring the weight value of the short ball supplied to the receiving unit 320 may be installed in the lower portion of the receiving unit 320. (See Fig. 3)

When the weighed weight value measured by the auxiliary load cell 322 is compared with a weight value preset by the weighing sensor unit 200 and the weighing sensor unit 200 deviates from a preset tolerance, It is preferable that a control unit is provided to enable supply of a short ball as much as the weight of the supplementary metering tank 140 branched from the discharge port 1100 of the storage unit 320 to the storage unit 320.

That is, when the weight value of the shot ball supplied to the receiving unit 320 is lower than the preset weight value in the auxiliary load cell 322, the control unit controls the supplemental weighing tank 140 so that the short ball inside the replenishing weighing tank 140 is supplied to the receiving unit 320 by an amount less than a preset weight value in the auxiliary load cell 322. [

The shot ball supplied to the input unit 100 is precisely metered by the metering sensor unit 200 and the shot ball supplied from the input unit 100 to each of the storage units 320 is supplied to the metering sensor unit 200, it is filled into the receiving unit 320 in the supplement measuring unit 140 for the remaining remaining weight value.

After the weighing sensor unit 200 and the auxiliary load cell 322 divide the first and second weights to precisely measure the short ball, the packaging container such as a saddle bag is closely attached to the lower part of the storage unit 320, By completing, the accuracy of the shot ball metering can be improved, as well as the reliability of the product can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention may be embodied otherwise without departing from the spirit and scope of the invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention, but to illustrate them, and the scope of the technical idea of the present invention is not limited by these embodiments.
