Description

Shock absorbing material for transportation of cathode ray tubes}

The present invention relates to a shock absorber for transporting cathode ray tubes, and more particularly, to a cathode ray transport transport shock absorber that allows a sufficient protection against heavy materials even after repeated use while smoothly fitting into an automated packaging facility.

Referring to FIG. 1, the cathode ray tube 10 joins the funnel 11 to the rear of the panel in which the shadow mask assembly is incorporated to form a vacuum bulb and an electron gun at the neck portion of the funnel 11. It has a structure in which the assembly 12 is mounted. Since the electron beam generated by the electron gun assembly 12 is properly deflected and scanned in front of the panel, an image is expressed, and thus is used as an output means of a TV receiver, a computer monitor, an oscilloscope, and the like.

At this time, the cathode ray tube is packaged, shipped, and transported in the semi-finished state as shown in FIG. 1 and put into the finished product assembly site. As a packaging material, multiple corrugated cardboard is generally used, but it is difficult to be molded into a complicated shape so as to be arranged compactly, and the durability is weak in repeated use, thereby increasing the logistics cost.

In addition, even when automated packaging equipment is used to reduce the man-hours, the robot is easily deformed when the robot is in operation to increase the number of man-hours for inserting the cathode ray tube into place. Moreover, it is difficult to expect the cathode ray tube to be laminated in a plurality of layers in order to increase the efficiency of packaging.

Accordingly, an object of the present invention is to provide a cushioning material for transporting cathode ray tubes, which allows a sufficient protection against heavy materials even when used repeatedly while being smoothly matched with automated packaging facilities.

The present invention relates to a shock absorbing material for protecting the cathode ray tube 10 in which the main parts of the electron gun assembly 12, the bands 13 and 14, the bracket 16, the dag 18, and the like are exposed to the outside. The outer band 14 is connected to the overlapping portion 14a, and there is a case where the inner band 13 is adjacent to the outer band 14. The bracket 16 is in a protruding state for mounting to a case in manufacturing a finished product such as a TV receiver. The dag 18 is applied in the appropriate range on the funnel 11 to stabilize the electron beam.

The present invention allows the cathode ray tube 10 on the lower plate 20, the intermediate plate 30, and the upper plate 40 formed of a foamed resin to be accommodated in a multilayer in a state in which at least one axis is symmetrically arranged. FIG. 1 shows that the cathode ray tube 10 is being accommodated between the lower plate 20 and the intermediate plate 30, and the intermediate plate 30 and the upper plate 40 are waiting in an overlapping state. Although the lower plate 20, the intermediate plate 30, and the upper plate 40 are used one by one, but the number of the intermediate plate 30, if necessary, it is possible to stack more multi-layer. As the foamed resin, it is advantageous to use EPE, EPP, EPS, etc. in terms of durability, but in general, EPS is widely used. The symmetrical arrangement of the cathode ray tube 10 in one axis is described with reference to FIGS. 4 and 5 to be described later.

At this time, the present invention is provided with a support means to maintain the position by engaging up and down with each cathode ray tube 10 in a state of forming the protection of the main portion. The support means may be selected from the intaglio portion 50 or the wall portion 90 connected by the ribs 95 of the indented groove structure. The engraved portion 50 is illustrated in FIGS. 1, 4 and 5 while the wall portion 90 is illustrated in FIG. 6 and will be described later. The intaglio portion 50 is formed on the upper surface of the lower plate 20, the upper surface and the bottom surface of the intermediate plate 30, the groove structure of the same dimensions on the lower surface of the upper plate 40. Since the intermediate plate 30 has the intaglio portion 50 on both sides, it is preferable to double the overall thickness of the lower plate 20 and the upper plate 40 to prevent the strength from being weakened.

The intaglio portion 50 is based on a shape close to an ellipse so as to accommodate the bottom surface of the cathode ray tube 10, and a triangular groove 58 is integrally extended to accommodate a portion of the funnel rearward. The band grooves 53 and 54 and the rectangular grooves 55 and 56 are formed to be in contact with each other at a constant pressure, while the triangular grooves 58 are formed to be inclined surfaces so that the dags 18 of the funnel are not in contact. The band grooves 53 and 54 and the first rectangular groove 55 vary depending on the size of the band 13 and 14, and the second rectangular groove 56 is deeper at both ends of the band grooves 53 and 54. It is formed to extend.

In addition, the lower plate 20, the intermediate plate 30, the side surface of the intermediate plate 30 in the present invention is formed side grooves 60 for loading / unloading. Side groove 60 is the size of the robot arm can be inserted in the automated packaging equipment and formed in communication with the intaglio portion 50 on the lower plate 20, the intermediate plate 30, the intermediate plate 30. Since the lower plate 20, the intermediate plate 30, and the upper plate 40 have the intaglio portions 50 of the same size, the respective side grooves 60 also coincide with each other when stacked as shown in FIG. 1.

In addition, the lower plate 20, the intermediate plate 30, the upper plate 40 in the present invention is provided with a groove 70 for even drying when forming the material. Since the recess 70 is formed in the space between the neighboring intaglio portions 50, the size and the position thereof vary according to the arrangement of the intaglio portions 50. Even drying is maintained through the grooves 70 in the process of drying after molding the foamed resin. Groove 70 is able to save the material while maintaining the strength because it also serves as a weight loss. Grooves 70 are necessarily formed on the bottom surface of the lower plate 20 and the upper surface of the upper plate 40, but may be omitted to prevent the strength from being weakened on the surface where the intaglio portion 50 is formed.

And FIG. 5A shows a 15 ″ (15 inch) CDT integral type with 16 cathode ray tubes 10 arranged in a symmetrical arrangement in the vertical and horizontal axes, and FIG. 5B shows a 17 ″ CDT integral type with 14 cathode ray tubes 10 mounted on the vertical axis. Accept only in symmetrical arrangement. The configuration of the side groove 60 and the groove 70 has the same identity as FIG.

FIG. 5C shows a 21 ″ flat CRT integral, in which eight cathode ray tubes 10 are housed in a symmetrical arrangement on the vertical and horizontal axes. In the form of supporting the cathode ray tube 10 through the wall portion 90, the same configuration as in FIG. 2 described above is applied, but unlike the above-described intaglio portion 50, the groove thickness is not required because the overall thickness is maintained evenly. not. Adjacent wall portions 90 connect to respective ribs 95 to reinforce strength.

FIG. 5D shows a 29 ″ general detachable, eight cathode ray tube 10 symmetrically arranged in a vertical axis and a horizontal axis, and FIG. 5E shows a 29 ″ flat CRT separated, eight cathode ray tube 10 symmetrically in a vertical axis and a horizontal axis. Housed in an array. The configuration of the side groove 60 and the groove 70 has the same identity as FIG.

As described above, it is advantageous for the plurality of cathode ray tubes 10 to be symmetrically arranged at least uniaxially in stabilizing the operation of the robot in an automated packaging facility. Typically, up to about 30 cathode ray tubes 10 are accommodated, and the same principle applies here.

Figure 6 is a schematic diagram showing the outer surface structure of the cushioning material according to the present invention.

According to the present invention, the lower plate 20 and the upper plate 40 may further include a plurality of beads 80 on the surface where the cathode ray tube 10 is not received. The lower plate 20 and the upper plate 40 absorb the impact by adding a bead 80 that protrudes to a certain height because the impact force from the bottom acts from time to time when the cathode ray tube 10 is stacked and transported. There is also an advantage. The city illustrates the form of a bead 80 that is spaced and spread in a square shape in a corner. The above-described groove 70 is formed on the surface on which the beads 80 are formed.

In the operation using the automated packaging equipment, when the lower plate 20, the intermediate plate 30, the upper plate 40 is put into the process in a stacked state, the arm of the robot lifts the intermediate plate 30 and the upper plate 40 When the cathode ray tube 10 is filled in this state, the intermediate plate 30 is lowered. When the cathode ray tube 10 is filled in the intermediate plate 30, the upper plate 40 is lowered to complete lamination. The stack is then bound with a band and placed in a box to complete the packaging.

According to the above configuration and action, the cathode ray tube transport buffer material of the present invention has a useful effect to allow a sufficient protection for heavy materials even when repeated use while smoothly matched with automated packaging equipment.
