Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a packaging device from a higher-level conveyor such as a supply conveyor for high-speed and continuous large-scale processing of easily damaged objects such as eggs and fruits. The present invention relates to an improvement of a support piece constituting a workpiece storage seat, which is a part of a device for safely transferring a workpiece to a lower conveyor such as.

(Prior Art) Automatic sorting equipment and packaging equipment for chicken eggs, fruits, etc. have recently been accelerated due to large-scale processing, and along with this, the risk of impact damage due to the movement speed of the processed object itself has increased. It was

In particular, it is well known that it is not easy to prevent the danger of high-speed transfer of the object to be processed from above to below in the apparatus.

The present inventor has succeeded in the technical development of "a device for transferring a vulnerable object to be processed from a discharge conveyor to a take-up conveyor" as disclosed in JP-A-60-110618, and is now commercialized. Has been put into practical use.

The outline of this transfer device is as follows.

An upper device and a lower device are horizontally arranged in two stages between an upper processing object discharge conveyor and a lower processing object take-up conveyor.

The upper device includes a group of individual storage seats with a seat bottom that can be opened and closed in a lateral direction for receiving the object to be processed discharged from the discharge conveyor.

The lower device that reciprocates up and down includes a group of individual accommodating seats having a seat bottom that can be opened and closed in order to receive an object to be processed discharged from the upper apparatus and discharge the object to a take-up conveyor.

The bottom of the accommodation seat of the lower device is released between the end of the descending stroke of the lower device and the beginning of the ascending stroke and can be closed before the end of the ascending stroke, and the seat bottom of the accommodation seat of the upper device is
When the lower device finishes the ascending stroke and the seat bottom of the accommodation seat of the lower device is closed, the seat bottom opening / closing means of the upper device, the seat bottom opening / closing means of the lower device, and the elevating means of the lower device are released. It has a linear reciprocating mechanism that works together.

Furthermore, the individual accommodating seats of the upper and lower devices are provided with a pair of front and rear supporting pieces at regular intervals, and a pair of straight rods are laid horizontally in parallel to form a set of four sheets that face each other in the front and rear and lateral directions. Formed in the voids between the support pieces. The seat bottom of the accommodation seat is opened and closed by expanding and contracting the distance between the pair of straight rods.

However, this transfer device still has some problems, and in particular, the above-mentioned upper and lower devices need to be improved.

(Problems to be solved by the invention) One of the above-mentioned problems depends on the size of an object to be processed, such as an egg, which has a large difference in shape depending on its size. There was an inconvenience that the upper and lower devices had to be partially replaced or adjustments had to be made.

The second problem is that the object to be processed is discharged downward from the high-speed conveyor, which is driven at a high speed, so that the object to be processed drops at a considerable speed. For this reason, it is easy to bounce while falling into the accommodation seat waiting at the bottom, and there is a risk that the ones themselves may lose their posture and their neighbors may come into contact with each other, resulting in damage.

(Means for Solving the Problems) This invention is a support seat component member for an object to be processed having a peculiarity that it is easily damaged and has an egg-shaped or spherical shape that easily rolls. The object of the present invention is to solve the above-mentioned problems by improving one of the pieces, and the gist is the following constitution.

Each supporting piece attached to the straight rod through the elastic member so that the accommodation seat of the object to be processed can be expanded, at least between the top and the hem of the part that is likely to come into contact with the object to be processed, A slanting sliding surface is provided having a curved portion that forms a bulge toward the outside of the accommodation seat.

(Operation) The object to be processed, which is conveyed at a high speed by the upper conveyor, drops onto the accommodation seat at a considerable motion speed. When the object to be processed is, for example, an egg, the energy of the drop resists the pressing force of the elastic member and expands the vicinity of the top of the set of four supporting pieces that form the accommodation seat, and the sliding surface that descends obliquely is formed. Glide into the accommodation seat.

Since each supporting piece to be formed is attached to the straight rod via the elastic member, this accommodation seat has an appropriate elasticity. In addition, there is a curved portion that forms a bulge toward the outside of the accommodating seat while the sliding surface extends from near the top to the hem. That is,
The inside of the accommodation seat is slightly inflated like a bag. Therefore, regardless of the size, the chicken egg plunging into the accommodation seat is softly sandwiched from all sides with moderate elasticity by the sliding surface having moderate elasticity in the bulge.

Therefore, the eggs are quietly and safely stored in the storage seat without bouncing.

Further, in this case, when the object to be processed spreads down the sliding surfaces of the four supporting pieces and slides down, each supporting piece elastically moves in the longitudinal direction of the straight bar with the attachment part to the straight bar as a fulcrum. Compress and tilt the member. The degree of this inclination generally corresponds to the size of the object to be processed, so that no special adjustment or the like is required.

(Example) Hereinafter, the present invention will be described based on an illustrated example in which an object to be processed is an egg.

First, the transfer device 1 of the embodiment will be described with reference to FIG. 5. The transfer device 1 includes a higher conveyor 11 and a lower conveyor.
It is installed between 21 and 21, and is composed of an upper device 2 and a lower device 3.

As shown in FIG. 1, the upper and lower devices 2 and 3 horizontally and horizontally extend a pair of straight rods 5 having a plurality of pairs of front and rear support pieces 4 mounted at regular intervals. Then, the accommodation seats 6 are formed in the spaces between the set of four support pieces 4 facing each other in the front-rear direction and the lateral direction. The seat bottom of the accommodation seat 6 is opened and closed by expanding and contracting the interval between the pair of straight bars 5.

In the drawings, a linear reciprocating mechanism for performing opening / closing of the seat bottoms of the upper and lower devices 2 and 3 and the lifting and lowering of the lower device 3 in a timely manner is omitted.

In the illustrated embodiment, as described above, the transfer of the object M to be processed from the upper conveyor 11 to the lower conveyor 21 is such that the upper apparatus 2 temporarily receives the object M discharged from the upper conveyor 11 and then the lower apparatus. It is carried out in two stages so that the lower device 3 which discharges the same to the lower conveyor 3 discharges it to the lower conveyor 21.

Here, the support piece 4 is made of a synthetic resin having a small friction coefficient, such as nylon or polyacetal, and is formed in a substantially saddle shape, and a square hole is formed at the center thereof. On the other hand, a stopper 7 for determining the front and rear positions of the pair of support pieces 4 is attached to the straight rod 5. Therefore, the support piece 4 is loosely fitted with the straight rod 5 into the hole, and is pressed against the stopper 7 by the spring 8 which is an elastic member attached to the straight rod 5,
It is attached to the straight rod 5. (See FIG. 1).

Further, according to the present invention, each of the four support pieces 4 forming the accommodation seat 6 has at least a portion that comes in contact with or is likely to come into contact with the object to be processed M from the top 4a to the hem 4b.
A sliding surface 4d is formed which has a curved portion 4c forming a bulge toward the outside of the accommodation seat 6 and descends obliquely. The curved portion
4c is the most characteristic of this invention.

In addition, if the shape of the support piece 4 is formed to be slightly longer in the vertical direction and the sliding surface 4d is slightly extended, a two-stage transfer of the workpiece M as in the embodiment shown in FIG. It can be safely transferred by handing over.

Further, in the illustrated embodiment, the case where a plurality of accommodation seats 4 are provided has been shown, but only one accommodation seat 4 may be provided if necessary.

(Effect) By improving the structure of the support piece constituting the object-to-be-processed seat, the discharged object can be received without bouncing and without losing the posture. Therefore, it is possible to more safely transfer the object to be processed which is easily damaged.

Therefore, it is possible to cope with the speeding up of a series of processing of the object to be processed, and further labor saving can be achieved.
