BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray, and more particularly, to a tray for a rotary drum of an automatic tray changer for supplying a workpiece to a automatic tray changer through a bogie.

In general, the head drum of a tape recorder such as a video cassette tape recorder (VCR) is to reproduce or record a signal recorded on a tape traveling along a certain driving path of the odometer. .

The head drum is mounted with an upper drum and a lower drum to which one or more video heads are attached, and a rotor and a stator transformer are interposed therebetween.

In addition, a drum motor is installed below the lower drum, and the upper drum is rotated according to the driving of the drum motor to perform a playback or recording function by the video head.

One example of the upper and lower drum processing steps constituting the head drum is described in FIG.

If the upper and the royal rum are cast by die casting, they are placed in a blank, that is, a workpiece to be machined.

The upper and lower workpieces are machined by roughing, and the holes are processed by drilling and tapping. In addition, the workpiece after the hole processing is finished to remove foreign substances such as cutting oil or oil contaminated on the surface through a washing process after finishing finishing (仕 上 加工).

In addition, after the washing process, the defective product is sorted out through the external inspection, and the workpiece of the upper drum is subjected to tape buffing processing and, optionally, a hard carbon film coating treatment. Through this processing process, the workpieces of upper and lower rum are manufactured as finished products and supplied to the head drum assembly line.

By the way, in roughing, hole and finishing of the workpiece, the machine is mainly used a numerical control machine tool, this numerical control machine tool is widely used as an automated means for improving the operation rate.

In an automated line employing such a numerically controlled machine tool, an automatic tray changer is used to continuously supply the workpiece to the numerically controlled machine tool, and the automatic tray changer mounts the workpiece on a tray for each machining process. Therefore, it is sequentially supplied to the processing machine.

Such automatic tray changers typically install a conveyor system or a chain type buffer in order to perform tray input and discharge operations.

However, the conveyor system or chain type buffer has to carry out the initial loading and discharging of the tray manually, which may cause damage to the product, increase worker fatigue, delay work preparation time, and increase productivity. This deterioration problem was brought about.

In addition, the installation space of the equipment is occupied excessively, the efficient use of the equipment is limited, and the initial equipment investment cost is increased, thereby reducing the economic efficiency. In addition, in order to transport the tray to the processing machine according to each processing process, a separate dedicated truck is required, and a lot of unnecessary time and place are required for the transport and waiting of this dedicated truck, which makes systematic work management and production management cumbersome and difficult. There was a problem.

In order to solve this problem, conventionally, an unmanned transfer truck is adopted to operate a direct numerical control method for integrating control.

However, the military management method not only requires excessive initial capital investment, but also causes abnormality in the group 1 machines, which affects the overall work line, resulting in a decrease in flexibility and productivity.

In order to solve this problem, the applicant has proposed an automatic tray changer 200 as shown in FIG.

This includes: feeding means for transferring the trays on which a plurality of workpieces are mounted into the feeding chamber 210; First lifting means for elevating the trays of the input chamber 210 to the working chamber 230; Means for clamping one tray located at the top of the trays; A robot 240 for sequentially supplying a workpiece mounted on the uppermost tray to a processor; Means for transferring the tray to the upper portion of the discharge chamber 220 when the workpiece to be processed by the operation of the robot 240 is again mounted on the uppermost tray; Second lifting means for lowering the trays positioned above the discharge chamber 220 therein; Discharge means for transferring the trays to the outside of the discharge chamber 220 is provided.

In this case, in the above-described automatic tray changer 200, in particular, the tray on which the workpiece is mounted is one of very important factors, which means that the workpiece mounted on the tray through the robot 240 is accurately maintained in the machining position. This is because not only the transfer to the processing chamber, but also the damage to the mounted workpiece is to be prevented.

To this end, the tray is required to be precisely positioned workpieces, that is, the upper drum and the lower drum, and to prevent breakage and deformation in the process of transferring through the robot 240. In addition, since the workpiece has to go through a washing process or the like, durability of the cleaning material is required.

3 shows a conventional tray on which such a workpiece is mounted.

This, the pad 2 of the epoxy resin material is attached to the entire surface of the bottom plate (1). The bottom plate 1 and the pad 2 are each provided with a plurality of mounting grooves 3 on which the workpieces can be mounted at predetermined intervals. In this case, the pad 2 is formed of an epoxy resin material to prevent damage to the workpiece when a drop impact or the like occurs.

However, in such a conventional tray, the upper surface of the pad in contact with the robot may be damaged by the relatively strong robot in the process of transporting the workpiece mounted on the robot through the processing chamber of the automatic tray changer. In particular, since a plurality of trays are stacked and put into the input chamber of the automatic tray changer, there is a possibility that surface damage of the pad may occur due to the weight of the stacked state.

In addition, in the transfer to the washing process to wash the workpiece, there is a problem causing the worker's fatigue and workability deterioration because the worker must be transported by hand rather than carried through the hanger of the washing machine.

In order to solve such a problem, another tray as shown in FIG. 4 is conventionally proposed.

It is provided with the square frame body 10 made of aluminum which forms the rectangular cavity 11 in the inner surface, The lower surface of the cavity 11 of this square frame body 10, for example, the lower column and upper drum of a to-be-processed state There is provided a seating portion 12 to which it can be mounted.

However, in such a conventional tray, it is very difficult to form the seating portion for mounting the royal rum and the upper drum, and also to form a rectangular frame body made of a metal material (for example, aluminum, etc.), resulting in a unit cost increase, and the weight is also very high. It was heavy and it was very difficult for the worker to handle it. In addition, problems such as corrosion occurs in the rectangular frame of the metal material by the cleaning material during the cleaning process.

The present invention was created in order to solve such a conventional problem, it is easy to load the workpiece, and can minimize the damage caused by impact or contact from the outside, and to facilitate the workability and cost reduction of the worker It is an object of the present invention to provide a tray for the low rum of the automatic tray changer.

In order to achieve the above object, a tray for a lower drum of an automatic tray changer according to the present invention has an internal surface in an automatic tray changer tray which is loaded with a plurality of workpieces in the state of a workpiece and supplied to the automatic tray changer through a bogie. A cavity having a quadrangular body formed therein, an upper edge formed at an inner side and an outer side thereof having a stepped portion, and a rim extending at both sides of the edge; Horizontal and vertical girders intersecting with each other from the inner surface of the cavity to form a lattice; Support bars formed in a grid in each direction of the horizontal and vertical girders; Seating parts provided at intersections of the support bars and seated at a lower rum in a workpiece state; It characterized by including the.

Such a characteristic configuration and the resulting effects of the present invention will become more apparent from the following detailed description of the invention with reference to the accompanying drawings.

FIG. 5 is a perspective view of a tray for royalum according to the present invention, FIG. 6 is a plan view, and FIG. 7 is a front view. 8 is an enlarged sectional view taken along line A-A of FIG. 6, and FIGS. 9 and 10 are state diagrams stacked on a trolley, and FIGS. 11 and 12 are state diagrams applied to an automatic tray changer.

And the present invention will be described with reference to the automatic tray changer shown in FIG.

As shown in the drawing, the present invention includes a frame 110 in which a cavity 111 of a quadrangular body is formed on an inner surface thereof. Edges 112 having stepped portions 112a and 112b are formed on upper and inner surfaces of the above-described frame 110, and rims 113 and 114 are formed on both side surfaces of the edge 112.

On the other hand, horizontal and vertical girders (120,130) (girder) are formed from the inner surface of the cavity 111 of the quadrangular body to cross each other to form a lattice shape.

In addition, a plurality of support bars 140 (support bars) are provided in a lattice shape by crossing each other in the upper direction of the horizontal and vertical girders 120 and 130.

In this case, in particular, a seating portion 150 is provided at the point where the support bars 140 intersect with each other in the above-described workpiece (B).

Support ribs 115 and 116 are formed on the side surfaces of the lower frame 110 of the above-described rims 113 and 114 at predetermined intervals. In this case, the support ribs 115 and 116 are clamping means of the automatic tray changer 200, that is, a portion clamped through the jaw 251. At this time, each of the outer surfaces of the support ribs 115 and 116 so as to be easily clamped through the clamper means of the automatic tray changer 200, that is, the jaw 251 has inclined surfaces 115a and 116a inclined outward.

At this time, the edge 112 of the above-described frame 110 is preferably such that two portions of the corners form the rounding portion 112c and two remaining corners are formed with the chamfers 112d, which is the tray 100. This is to match the assembly position of each other in the process of laminating a plurality of.

In addition, it is preferable to provide the windows 117 and 118 and a hanger hole (H) on both sides of the frame 110 described above, which is unnecessary when stacking a plurality of trays 100 through the windows 117 and 118. When the trays are stacked, that is, for example, when the trays for upper drums are stacked, this is to easily identify. In addition, the hanger hole (H) is a portion inserted into the hanger of the washing machine for washing the workpieces loaded on the tray 100, through which the workpieces loaded on the tray 100, that is, the lower rum (B) It can be easily cleaned.

In this case, it is more preferable that the aforementioned windows 117 and 118 are divided into left and right windows 117 and 118 by the display unit 119, respectively. This is to prevent this, because it is not possible to reliably distinguish whether or not the other trays are mounted when the trays having the grooves extending to the side are stacked.

On the other hand, when looking at the structure of the seating portion 150 in which the low rum R in the workpiece state is seated, the hubs 142 of predetermined lengths are formed at the intersections of the support bars 140 in the upper direction. At this time, the outer diameter of the hub 142 is inserted into the shaft hole of the low column (B) in the above-described workpiece state.

At this time, in the stacking of a plurality of trays 100 directly below the intersection of the support bars 140, a low rum in the workpiece state seated on the seating portion 150 of the tray 100 located directly below The flange portion 141 is formed to extend to a predetermined length in order to prevent B) from being separated to the outside by an external impact or the like and to attain a reinforcing role.

On the other hand, the above-described frame 110 and the horizontal and vertical girders (120,130), the support bars 140 and the seating portion 150 is integrally molded with a material of polyphenylene sulfide resin (PPS; POLYPHENYLENE SULFIDE RESINS) This would be desirable.

This is because polyphenylene sulfide resin is a highly crystalline chain polymer having a benzene ring as a bone structure, and exhibits excellent and stable material properties in all environments (heat resistance, oil resistance, chemical resistance, etc.). Since it is a resin (Super EP), when integrally molded through this, damages due to impact or contact with the robot 240 can be prevented in advance, and damage to the rodum in the state of the mounted workpiece is performed. This can be prevented.

The use example of the tray which concerns on this invention comprised in this way is demonstrated.

First, FIG. 8 illustrates an example in which a plurality of trays 100 of the present invention are stacked. First, the lower column B of the workpiece state is formed at the outer diameter of the hub 142 protruding at the intersection of the support bars 140. Insert the shaft hole of

In addition, in the case of stacking a plurality of such trays 100 and supplying them to the input tray 210 in the automatic tray change 200, for example, the plurality of trays 100 may be stacked and supplied through the trolley 300 as shown in FIG. 9. .

This will be described in more detail, and a plurality of trays 100 are stacked on the loading part 320 of the trolley 300. At this time, the lowermost tray 100 is free to be transported by the roller 311 of the rail portion 310 of the trolley 300.

Meanwhile, in this case, when the trays 100 are stacked, the lower part of the frame 110 is supported by the stepped portions 112a and 112b of the edge 112 and sequentially stacked, and the trays 100 are rounded portions of the edge 112. It is laminated stably by the chamfer 112d of 112c. That is, the trays 100 are sequentially stacked without shifting due to injection error during injection molding.

At this time, in stacking a plurality of trays 100 sequentially on the rail portion 310 of the trolley 300, the trays on which the other trays 100, for example, the upper drum, are mounted by the windows 117 and 118 formed in the frame 110. The presence or absence of the mounting can be easily determined. This is because the windows 117 and 118 are divided by the display unit 119 so that this can be easily determined when the other trays are mounted.

In this way, by moving the trolley 300 having a plurality of trays 100 stacked using the wheels 330 and the handle part 340 to move to the standby space or the input chamber 210 of the automatic tray changer 200, the tray can be easily moved. The low rum B in the state of the workpiece loaded on the 100 can be supplied. Meanwhile, in the process of transferring the above-described bogie 300, the 100 located at the lowermost end of the tray 100 stacked on the rail 310 has its flow through the stopper means 350 of the bogie 300. Easily prevented.

Meanwhile, in FIGS. 11 and 12, the tray 100, which is supplied to the input chamber 210 of the automatic tray changer 200 by the trolley 300 and is supplied to the work chamber 230 by lifting means, is clamped. The process of doing so is illustrated.

When the position of the uppermost tray 100 supplied to the work room 230 by the lifting means is detected by the sensor 253 mounted in the upper center of the clamping plate 252, the cylinder is operated to guide the rail. The guide block is conveyed toward the movable plate shaft along this.

At the same time, as the clamp plate 252 is transferred, the lower surfaces of the rims 113 and 114 are respectively supported on the upper side of the jaw 251 to clamp the tray 100. At this time, the inclined surface 251a of the jaw 251 prevents interference generated between the jaws 251 and the stepped portions 112a and 112b of the edge 112, and the inclined surface 251b of the jaw 251 on the lower side. This prevents the interference generated between the jaw 251 and the edge 112 of the tray 100. In addition, the groove of the inclined surface 251 b prevents interference generated at the ends of the rims 113 and 114.

In addition, the inclined surface 251a of the jaw 251 contacts the inclined surfaces 115a and 116a of the support ribs 115 and 116 and is clamped to prevent the flow of the tray 100, and the guide plate 254 and the support plate 255 are prevented. Since the front and back of the tray 100 firmly hold each, the flow of the tray 100 is prevented.

In this way, the robot robot 240 of the tray 100 transports the workpiece mounted on the tray 100 to the supply line of the conveyor system and starts the processing operation.

In addition, the tray 100 in which the work column of the lower column B of the work state is mounted is inserted into the hanger of the washing machine through the hanger holes H formed at both sides of the windows 117 and 118, thereby completing the processing work. It will be easy to wash the wardrum (B) in the workpiece state. At this time, the fear of deformation due to cutting oil, oil, washing liquid, etc. during the washing process will be effectively prevented because the material of the tray 100 itself is molded in excellent polyphenylene sulfide re-roll roll in all environments.

On the other hand, the above-described embodiment is merely to describe one preferred embodiment of the present invention, the scope of the present invention is not limited to such, and can be changed appropriately within the scope of the same idea, for example, It is applicable.

As described above, according to the tray for the row rum of the automatic tray changer according to the present invention, it is very easy to mount the ward rum in the state of a plurality of workpieces on the tray, and it is possible to supply these to the automatic tray changer through the bogie and this bogie. There is an easy advantage.

In addition, since the tray itself is integrally molded using a material of polyphenylene sulfide, there is an effect that the ease of molding and damage of the royal rum in the mounted workpiece state can be easily prevented.
