Description

[Detailed explanation of the invention] <Technical field> This invention is a reversible leftover dish that removes leftover food and leftover vegetables from lunch boxes and other tableware used for school lunches and catering before they are washed. Regarding the drop machine.

The present applicant previously proposed, in Japanese Patent Publication No. 56-48407, etc., a reversible food scraps removal machine that includes a bucket conveyor equipped with a bucket for storing lunch boxes, etc., and a feed roller or rod conveyor installed below the tip of the bucket conveyor. did. This type of reversing type waste removal machine transports lunch boxes by placing them in the bucket of a bucket conveyor, and when the bucket is conveyed to the end of the conveyor and is reversed there, the lunch boxes inside the bucket are sent downward. The structure is such that the bento box is inverted and dropped onto the rollers, and at that time the leftover food in the bento box is dropped between the feeding rollers and the leftover food is removed. Even at the end, the bento box in the bucket was turned upside down and dropped onto the lower feed roller, which caused the falling posture and position of the bento box to be disturbed, and leftover food from the bento box could not be removed properly. .

<Purpose of the invention> The present invention was developed in consideration of the above points, and the tableware such as lunch boxes conveyed by a bucket conveyor is forcibly dropped onto the conveyor below, and the tableware is removed from the tableware. To provide a reversible food waste removal machine capable of effectively removing food waste.

<Structure of the invention> For this purpose, the present invention installs a bucket conveyor that transports tableware in a bucket, and a feed conveyor is installed below the end of this bucket conveyor to collect the dishes that have fallen due to the reversal of the bucket. In a reversible food scraper that receives dishes on a feed conveyor and drops them from the gap, the bucket of the bucket conveyor is pivotally supported on both sides by the conveyor chain so that it can be reversed in the direction of travel. A reversing extrusion device equipped with a pushing member near the end of the conveyor that forcibly pushes out the bucket that has started rotating in the reverse direction in the reverse direction. It was constructed by installing it nearby.

<Example> Hereinafter, an example of this invention will be described based on the drawings.

Fig. 1 shows a schematic cross-sectional view of the reversible waste scraper, and Fig. 2 shows an enlarged view of the same. A plurality of buckets 3 are rotatably supported between conveyor chains 4 at predetermined intervals. In other words, the bucket 3 has a shaft 5 on both sides of its front part.
The bucket is pivoted on the conveyor chain so as to be rotatable in the direction of travel of the conveyor, and the bucket that has moved to the end of the upper part of the bucket conveyor 1 is attached to this shaft 5 at the upper left end.
is inverted around the center.

Reference numeral 6 denotes a reversing extrusion device disposed inside the terminal end of the bucket conveyor 1, in which an extrusion cylinder 8 is fixed to a mounting frame 7 facing obliquely upward, and the tip of the piston rod of the extrusion cylinder 8 rotates in the reversal direction. A pushing member 9 is attached to push out the bottom of the bucket 3 of the bucket conveyor 1 that has started in the reverse direction. 1
Reference numeral 0 denotes a striking member, which is disposed at a position where the tip of the bucket cart 3 that has been reversed approximately 180 degrees at the end of the bucket conveyor 1 strikes.

A feed conveyor 11 is installed below the terminal end of the bucket conveyor 1, which receives the dishes 20 that have fallen due to the reversal of the bucket 3 and sends them to the next processing step.
As the feeding conveyor 11, a conveyor capable of dropping the leftover food in the tableware 20 downward is used, such as a rod conveyor in which a large number of rods are connected at intervals between conveyor chains on both sides. 12 is a leftover container placed below the feed conveyor 11.

Next, I will explain the operation of the reversible leftover machine.
Tableware 20 such as a lunch box containing used leftover food is placed in a bucket 3 of a bucket conveyor 1 that is driven leftward in FIG. 1, and slowly conveyed leftward. When each bucket 3 is conveyed to the end of the conveyor, it starts rotating in the reverse direction, as shown in FIG. At this time, when the position of the bucket is detected by a position detection means such as a limit switch (not shown), the extrusion cylinder 8 of the reversing extrusion device 6 operates to push out the extrusion member 9, and the extrusion member 9 is applied to the bottom of the bucket 3. This acts to forcibly push out the bucket 3 in the reverse direction. The bucket 3, urged in the reverse direction by the extrusion member 9, rotates about 180 degrees around the shaft 5 and hits the tip of the bucket against the striking member 10, whereby the tableware 20 inside the bucket 3 Lower feed conveyor 11
The leftover food therein falls from the gap in the feed conveyor 11 into the leftover food container 12 below and is removed from the tableware 20. Thereafter, the tableware 20 is conveyed by the feed conveyor 11 to a washing machine (not shown) and is washed.

In the above embodiment, the extrusion cylinder 8 was used in the reversing extrusion device 6, but instead of the extrusion cylinder 8, an extrusion system consisting of a motor equipped with a speed reducer and a one-rotation clutch, and a crank mechanism rotationally driven by the motor is used. Various drive mechanisms such as a mechanism for pushing out the pushing member 9 in the reverse direction can be used.

<Effects of the invention> As explained above, according to the reversible food waste removal machine of the present invention, the bucket of the bucket conveyor is pivotally supported on the conveyor chain so as to be reversible in the direction of travel, and the bucket is mounted near the end of the bucket conveyor. A reversing extrusion device is provided with a pushing member that forcibly pushes out the bucket cart that has started rotating in the reverse direction, and a striking member is provided near the end of the bucket conveyor for the tip of the bucket cart to hit when it is reversed. It was configured as follows. For this reason, the bucket that has started to reverse at the end of the conveyor is urged to be pushed out by the extrusion member and is reversed, allowing the tableware such as lunch boxes to fall with some force onto the feed conveyor directly below. Even when the bucket conveyor rotates slowly, the dropping attitude and position are not disturbed when the bucket is reversed, and the leftover food therein can be smoothly dropped and removed by the shock caused by the dropping of the dishes.
