[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller body transport tray for accommodating and transporting a roller body having a roller portion and core rods protruding from both ends of the roller portion.

[0002]

2. Description of the Related Art Conventionally, when a roller body to be assembled in a printer or a copying machine is transported from, for example, a roller body factory to an assembly work station, the roller body is mounted on a roller carrier shown in FIG. Was there. In this carrier, two supports made of foamed resin are mounted in parallel on both side edges of corrugated cardboard, and this support is provided with a large number of lateral grooves for sandwiching a core rod.

The above-described roller carrier was handmade because it had a structure not suitable for mass production, but with the increase in the production amount of rollers, the time and effort required to manufacture the carrier could not be ignored. Further, since this carrier is bulky, there is a problem in that it requires a place for storage before use, and corrugated paperboard is worn during use to generate scraps, which adhere to the roller surface.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the conventional roller carrier.
It can be mass-produced and can be stored compactly before use.
It is an object of the present invention to provide a means for accommodating / transporting a roller body that does not generate wear debris during use.

[0005]

Thus, according to the present invention, (1) a single-layer or multi-layer structure for accommodating and transporting a roller body having a roller and core rods protruding from both ends of the roller. A tray formed of a synthetic resin sheet, which has a dish-shaped recess having a depth capable of accommodating the roller, and a tray which has an upper surface and is continuously connected to the dish-shaped recess and hangs down a peripheral edge of the dish-shaped recess. A side wall of a predetermined height that surrounds the outer side of the barrier part and spreads downward, and further includes a roller support part that accommodates and supports the roller at the bottom of the dish-shaped recess. , Front and rear core rod support portions sandwiching and supporting both ends of the core rod before and after the roller support portion, between the front core rod support portion and the roller support portion, and the rear portion. Between the core rod support part and the barrier part of There is provided a tray for transporting a roller body, the tray having a recess provided downward.

In using the tray for transporting the roller body according to the present invention, both ends of the core rod of the roller body are sandwiched between the front and rear core rod supporting portions. Then, the roller of the roller body comes into contact with and is supported by the roller support portion provided in the center of the tray. Thus, the predetermined number of roller bodies can be aligned in the dish-shaped recesses of one tray in parallel and stably accommodated. If the tray is large, the dish-shaped recess should be two or three along the roller direction.
It may be divided into individual parts. In this case, each part is divided by the barrier part, which prevents sagging of the central part due to bending when the whole is made into one dish-shaped recess. In addition, although the tray is generally rectangular in plan view, it may have a shape close to square depending on the shape of the roller body.

The trays containing the roller bodies are stacked one above the other and put in a returnable box for storage or transportation. In that case, by stacking the trays in the front-rear direction alternately, the trays are provided between the roller support portion of the upper tray and the front core rod support portion, and between the rear core rod support portion and the rear barrier portion. The bottoms of the two recesses are in contact with the tops of the core rod support portions of the lower tray. As a result, the upper side surface of the core rod of the roller body housed in the lower tray is pressed by the bottom surface of the depression, and the space between the upper and lower trays is defined.

A tray for transporting roller bodies according to the present invention is
Since the synthetic resin sheet is molded by, for example, a vacuum molding method, it can be mass-produced. Since empty trays can be stacked on top of each other without a gap, a large number of trays can be stored in a relatively small space. Further, since the abrasion of the tray of the present invention hardly occurs during use, the situation of adhesion of the abrasion to the roller surface is improved.

The synthetic resin sheet used in the present invention is selected from the sheets of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polystyrene, ABS resin and the like, and the sheet may be in a single layer form or a foam of the above resin. It may be a laminated sheet in which a sheet and a single layer sheet are laminated by fusion or adhesion. The laminated sheet has a two-layer structure, or 3 with a foam sheet sandwiched in the middle.
It may have a layer or four-layer structure. When manufacturing the roller body transport tray of the present invention from these synthetic resin sheets, a known vacuum forming method can be used.

BEST MODE FOR CARRYING OUT THE INVENTION As a preferred embodiment of the present invention, (2) a rotationally asymmetric position with respect to the center point of the planar shape of the tray on the upper surface of the barrier portion formed wide before and after the dish-shaped recess. The roller body transport tray according to (1) above, wherein a recess having a predetermined depth shallower than the height of the side wall is formed downward from the upper surface.

The width of the upper surface of the barrier portion is formed, for example, wider before and after the dish-shaped recess than on the left and right of the dish-shaped recess. In the present embodiment, a recess is formed downward from the upper surface of the barrier portion before and after the wide dish-shaped recess. A part of the recess may be associated with the side wall, and the side wall of the part may be recessed inside the tray. The position where the recess is provided may be, for example, a position that is rotationally asymmetric with respect to the center point of the planar shape of the tray. In this way, when the two trays are stacked with the front and back being different from each other, the positions of the depressions do not shift and do not overlap each other vertically. The depth of the depression should be slightly shallower than the height of the side wall. In order to improve the strength of the tray, vertical ribs may be provided at arbitrary intervals on the inner peripheral wall surface of the depression, the outer peripheral portion of the side wall, the upper wall surface of the barrier portion, the peripheral portion of the dish-shaped recess, and the like. Good.

When the two trays provided with the depressions of this embodiment are stacked in a staggered manner in the front-rear direction, the bottom surfaces of the depressions of the upper tray contact the upper surface of the barrier portion of the lower tray,
This defines the space between the upper and lower trays. The tray spacing in this case is selected so as to match the tray spacing defined by the depression described in (1) above. By providing the depressions of this embodiment at several positions on the upper surface of the barrier of the tray, the parallel relationship between the upper and lower trays can be stabilized.

Further, in the above state, the lower edge of the side wall of the upper tray covers the upper portion of the lower tray, so that the upper and lower portions are
Relative lateral movement between the trays of sheets is prevented.

When stacking empty trays in the same direction, the shapes of the respective parts including the recesses of the present embodiment are the same in the upper and lower trays, so that the empty trays can be stacked in a compact shape without any gap between the upper and lower trays. .
