Description

[Detailed description of the invention] When packaging chicken eggs for retail sale, 6 to 12 eggs are packaged.
Separate the eggs into two rows and have individual storage seats to prevent them from coming into contact with each other.In a container called an egg carton, the eggs are lined up in a container with the sharp end facing down and the blunt end facing up. Common.

In recent years, automatic packaging machines for eggs have made remarkable progress, and the automation of retail packaging as described above has rapidly become widespread. Along with this, there has been a demand for automating the process of inserting a label with the size code, province of production, date of packaging, etc. printed into the container. In order to meet this demand, several automatic devices of this type have already been proposed.

However, the reality is that all of them have some kind of problem, and rice cannot be considered satisfactory. The most common problem is the reliability of inserting labels one by one in a constant position into the narrow gap between two rows of eggs in containers that are being transported at a considerable speed. It means that it is scarce.

Moreover, the prices cannot be called cheap.

The present invention is intended to easily and inexpensively provide this type of device that is highly adaptable to container conveyance speeds and has a highly reliable label loading operation.

To explain the figures, reference numeral 1 denotes a label loading chamber, the bottom of which is open except for the label support section 2 on three sides, as illustrated in FIG. Reference numeral 3 denotes a label posture regulation chamber provided below the loading chamber 1, which is composed of a label support member 4 in an upright position and an opening/closing member 5 facing the label support member 4 in a V-shape. A suction cup tear 6 is attached to a swinging rod 7 and swings vertically between the loading chamber 1 and the posture adjustment chamber 3, and is connected to a suitable vacuum device (not shown) via an air valve 8. At the same time, the air valve 8 is opened and closed as the air valve 8 swings. In the drawing, a rotary type air valve 8 is installed horizontally, and a swinging rod 7 is attached to its rotating portion 9 together with a gear 10. The following is an example of a case in which the part 9 and the swinging rod 7 are made to swing together. The timing relationship between the opening and closing of the air valve 8 and the swinging of the swinging rod 7 is such that the suction cup 6 rises to suck only one label L from the bottom of the loading chamber 1, and then descends to the posture regulation chamber 3. It is set so that it can be released when approached. The posture regulation chamber 3 is formed into a deep V-shape by the label support member 4 in an upright position and the opening/closing member 5 facing it in a 7-shape. It becomes a posture. This is the posture with the lowest air resistance when falling into the container 14, so that a sufficient falling speed can be obtained and there is no risk of the posture collapsing during the fall. In the drawing, the bottom of the posture regulation chamber 3 is opened and closed using a contact rod 16 coaxial with the opening/closing member 5.
At the same time, the return spring 17 is tensioned, and the upper end of the eggs 19 filled in the container 14 and conveyed by the conveyor j8 touches the contact rod 16, so that the bottom of the 7-shaped chamber is opened. , a case is illustrated in which the label L falls at that moment and is then closed again.

In order to supply the next label L in the posture regulation chamber 3 after it has fallen, a reflective photosensor 20 is installed in the gap between the two label support members 4.4 forming the posture regulation chamber 3 in the drawing. In this example, the absence of the label L is sensed, and the signal is used to rotate the motor 12. A flexible guide member 21 is provided at the lower end of the label support member 4 to protrude downward, and its tip end, that is, its lower end, is set to a length that reaches the gap between the left and right side of the chicken eggs 19. As a result, the labels L falling from the posture regulation room 3 fall along the guide member 21 and are accommodated in the narrow gap between the front and rear rows of chicken eggs 19 in a fixed vertical position.

In general, the faster the egg 19 is transported, the more turbulent air is generated near the top of the egg group, which tends to disturb the direction and posture of the falling labels, but the guide member 21 sufficiently prevents this. You can.

As described above, the present invention can be applied not only to packaging containers for chicken eggs, but also to similar packaging containers for foods and other foods, by placing the labels one by one at a predetermined position on the container in a fixed posture. You can put it in.

The structure is also extremely simple and robust.

Claims (4)

[Claims] (1) In the packaging process of eggs, etc., the container filled with eggs is installed on a conveyor that is conveyed in an open state, and it relates to a device that inserts labels one by one into the containers passing under the conveyor. A label loading chamber is provided above, a label posture regulation chamber is provided below, and between the two, a suction cup connected to a vacuum device and an air valve is provided so as to be able to swing freely in the vertical direction. The posture regulation chamber senses the approach of the container and opens its bottom, and the swinging of the suction cup is caused by a signal emitted by a sensor that detects the presence or absence of a label in the posture regulation chamber. 1. A device for inserting labels into egg packaging containers, etc., characterized in that the device is controlled by: (2) The device for inserting labels into egg packaging containers, etc. according to claim 1, wherein the loading chamber is formed in an open state except for the label supporting portions on three sides at the bottom of the loading chamber. (3) The apparatus for inserting a label into an egg packaging container or the like according to claim 1, wherein the posture regulation chamber comprises a label support member in an upright position and an opening/closing member facing the label support member in a V-shape. (4) The label feeding device for an egg packaging container or the like according to claim 3, wherein the label supporting member has a flexible guide member protruding downward from the lower end thereof.
