Description

[Detailed Description of the Invention] The present invention relates to an improvement in a top shock absorbing device for a tray used in a fruit sorting machine that transports various fruits and vegetables one by one on a bucket with a tray.

Conventionally, as shown in Fig. 1, a cushioning material 1 such as a sponge made of foamed rubber or soft resin material is attached to the upper surface of the saucer with an adhesive 2, or the saucer is molded with resin as shown in Fig. 2. In this case, the buffer cover covering the top surface of the saucer is not placed in close contact with the saucer, but instead a rib 3 or pin 4 is provided on the saucer side so that there is a gap in the area other than the ribs 3 or pins 4. However, products with sponges and other adhesives have disadvantages such as their elasticity decreases as the sponge ages, making them less durable, and the fuzz of fruits such as peaches gets stuck and becomes hard. Because it was glued together, there was a drawback that the tare weight could not be made uniform. Furthermore, the system shown in Figure 2 has a partial buffering effect, but since there are ribs and pins that act as receiving parts for the cover provided on the saucer side, these parts become non-buffering parts in the form of stripes or dots. There was a flaw that shocked the fruit as it ripened.

Also, similar ones include Utility Model Application Publication No. 53-27049,
The one disclosed in Japanese Utility Model Application Publication No. 53-28156 has been proposed, but the one in Japanese Utility Model Application Publication No. 53-27049 has a closed air chamber between the cup and the elastic cup. An air chamber is formed by partially forming a depression in a wall surface or a part of the outer peripheral surface of the elastic cup. However, the air chamber is only partial, and the target fruit ranges from extremely large to extremely small, so some fruits may fall into areas that do not have an air chamber, and depending on the method of feeding, they may hit the upper rim of the cup and damage the fruit. There was a drawback to giving. Also, in the case of Utility Model Application No. 53-28156, the cushion material is attached tightly to the inside of the cup. However, the same cushion material cannot provide an appropriate cushioning effect for fruits ranging from extremely large to extremely small, and the disadvantage is that it may cause some damage to the fruit, and the locking protrusion has a head that is closer to the hole provided in the cup. Because of the large size, the volume of the head of the protrusion cannot be reduced, and in reality, it is difficult to put on and take off, and when using a soft cushion material that expands and contracts, the head is mopped and damaged, resulting in a lack of locking function.

The present invention was made to eliminate these drawbacks, and uses a flexible/elastic material such as rubber, vinyl acetate, or soft PVC for the upper surface cover of the saucer to provide a buffering effect, and the upper inner surface of the saucer is A certain gap is provided on the upper surface of the upper edge of the saucer, and in order to install it without using adhesive, the upper edge of the saucer is inserted and a hollow hook is provided on the bottom of the saucer. It is formed so as to fit into the hole to serve as a cushion cover, and is also formed with an appropriate amount of space so that the space will not be crushed by the size and shape of the saucer and the weight of the selected fruits such as fruits and vegetables to be placed on it. In order to maintain the cushioning effect on the selected fruits, the cushion cover has a rod-like, fin-like, or various other shapes on the back surface of the cushion cover, and has elasticity that can be appropriately bent and expanded when fruits and vegetables are added. The body protrusions are scattered at appropriate positions, and the gap between the cushion cover and the saucer and the elastic protrusions act as a buffer against the impact caused by the insertion of selected fruits, and the attachment and detachment of the saucer and the cushion cover is facilitated. It is designed to be easy to use.

FIG. 3 showing an embodiment of the present invention will be explained below.

5 is a tray for fruits and vegetables used in various fruit sorting machines, and is used in weight sorters, shape sorters, transport bucket conveyors, etc., and is used in various ways for conveyor chains that run and rotate. Installed in multiple distances.

Reference numeral 6 denotes a cushion cover that is attached to the upper surface of the saucer, and is made of a flexible/elastic material such as rubber, vinyl acetate, or soft PVC, and covers the upper surface of the saucer 5 and the upper edge of the saucer 5 according to the size and shape of the saucer 5. A gap 7 is formed at an appropriate interval between and, and the upper peripheral edge 6a is formed so as to enclose and fit the upper end of the saucer. 6b is cushion cover 6
This is a hook provided at the center back side of the cushion cover, and is inserted into the hook hole provided at the center bottom of the saucer 5 to fix the center portion of the cushion cover. Part 6b
It is formed into a hollow shape to reduce the volume (outer circumferential diameter). Reference numeral 8 denotes an elastic protrusion provided on the back side of the cushion cover 6 to support the gap 7 between the saucer and the cushion, and is usually molded integrally with the cushion cover from the same material and shaped like a rod or fin of several millimeters. They are scattered at appropriate positions on the tray so that when fruits are placed, they bend, expand and contract appropriately to act as a cushion. Depending on the size and shape of the saucer 5, the elastic protrusion 8
may be attached to the cushion cover 6 using a sponge or the like made of a different material.

As described above, the present invention uses a saucer cushion cover made of a flexible elastic material that can be fitted into the tray and manufactured by injection molding, so it is not only easy to attach to the tray, but also suitable for weight sorting machines. You can obtain a high-quality saucer that is ideal for the saucer.

Furthermore, although the present invention is equipped with a hook portion for fixing the central portion of the cushion cover to the hole at the bottom of the saucer, since the hook portion is hollow, the volume of the hook portion (outer diameter ) can be reduced and can be attached and detached repeatedly without damaging the head of the hook.

Furthermore, in the present invention, a space is provided between the cushion cover and the saucer, and the entire upper surface and upper edge of the saucer are formed in an air cushion type, so that even soft fruit can be provided with an appropriate cushioning effect. Even if a soft fruit hits the upper edge of the saucer due to improper loading, the fruit will not be damaged, and the gap is supported by an elastic protrusion that bends and expands appropriately, so any part on the saucer will not be damaged. However, it can provide a moderate cushioning effect. In addition, since the cushion cover does not use a sponge with air bubbles, there is no longer a problem where the fluff of fruits such as peaches gets stuck in the cushion cover and hardens, resulting in a durable, high-quality saucer that does not damage the fruit, making it more economical. The effect is huge.
