Abstract

PURPOSE:To feed the food reliably with good timing by inverting it with a twist chute and controlling the opening/closing timing of a shutter to feed it to the next process in the said device for cake, etc. CONSTITUTION:The food 1 inverted by a twist chute 2 is dropped to a chute 3 from the chute 2 and is fed to a shutter 4. The shutter 4 is reciprocated between I and H in consistency with the transfer timing of a transport conveyor 6 to the next process, and the food 1 is fed to the conveyor 6. According to this constitution, reliable feeding is available and efficiency is improved.

Description

Detailed Description of the Invention The present invention is a front-side reversal supply method in which foods such as confectionery, which are arranged on the front or back side, are reversed using a twist chute and then fed to the next process in a timely manner by a shutter equipped with a supply function. It is related to the device.

When the shape of the food is hemispherical with a flat part and an unstable surface part such as a spherical surface, or when the top of a cone is cut off and the top is unstable like a trapezoid, etc. ,
From the stable side down (this is called the front side),
When it is necessary to invert this with the unstable side facing down (this is referred to as the back side), it is particularly difficult to reliably invert and supply all the pieces since the unstable side is facing down.

A conventional example is explained with reference to FIG. 1. Two stages of conveyors a and b are provided, and food (11) arranged face up is conveyed on the upper conveyor a, and the food (11) is conveyed on the top conveyor a, lower b
There is a method of flipping the paper 180 degrees when it falls onto the conveyor so that the entire surface is on the back side. This method is useful when processing large quantities.
The drawback was that there was a lack of certainty.

The present invention allows foods such as sweets arranged on the front or back side,
Using a twist chute, it is given a twisting angle so as to be reversed 180 degrees and dropped, and is closed and opened by the reciprocating circular movement of a shutter with a supply function installed in the direction of movement, thereby stopping it. This is a device that repeats the process of supplying the raw material to the next process in a timely manner.

The structure of the present invention will be explained with reference to the embodiments shown in the drawings.

Twist chute (21 in the drawing) gives a twisting angle to the hemispherical food (1) on the surface at the entrance and 18 at the exit.
It is inverted by 0 degrees, and explanatory diagrams of cross sections at seven locations in between are shown in FIGS. 3(A) to 0. In FIG. 3, the top surface is open to make it easier to remove food if it gets stuck and to manage the reversing process, but it is not necessary to open the top surface.

In general, for food products, which often have a light responsibility, it is desirable to reduce the resistance on the inner surface of the twist sheet as much as possible, and to achieve this, better results can be obtained by selecting the material of the twist sheet and treating the inner surface of the twist sheet. It will be done.

It is desirable that the inclination of the twist sheet be the minimum angle necessary for the food to slide under its own weight. This prevents the paper from floating up, popping out, or becoming jammed during the reversal process, making it possible to perform the reversal smoothly and reliably.

The one-dot chain line of the twisted sheet in Figure 2 indicates the locus (2) → 0 of the center point of the top and bottom of the food when the cross section of the twisted sheet is 4~(q in Figure 3). This is a curve.

The twisting direction of the twist sheet may be left twisting or right twisting, and although it was explained as a 180 degree reversal, it can be used for the purpose of changing the angle of the position of food from any angle to any angle. It is also possible.

The food (1) is fed one by one with the front or back side aligned onto the twist sheet, and the food (1) that has been completely turned over by the twist sheet is processed by the shutter (4) equipped with a feeding function by 31 ), but if it is unstable, especially on the back side, twist this sheet to make the slope of the sheet even smaller to reduce the speed at which it slides and keep it as stable as possible. It is necessary to

The shutter with a feeding function supplies the food to the conveyor (6) to the next process in a timely manner (Fig. 2).It makes a reciprocating circular motion between H and then stops at H to keep the food stable. state, moves in the ■ direction, and is supplied to the conveyor that connects to the next process.

In the case of food that has slipped down sheet f31 and is unstable, especially on the back side, a stopping guide ( 5). However, since it is generally in a stable state when it is inverted to the front side, it is sufficient to change the shape of the feeding portion of the shutter depending on the shape of the food to be fed, and a restraining guide is not necessarily required.

As described above, by carrying out the present invention, it has become possible to reliably turn over all the food products on their front or back sides and to supply them to the next process.

In particular, it is effective for reversing and feeding foods from the front side to the back side, such as foods having a shape having a flat part and an unstable surface part such as a spherical surface.

The present invention can be connected in a straight line, including the connection with the previous and subsequent processes, and does not require complicated equipment, so it does not require space. I was able to increase the effect.
