Abstract

PURPOSE:To obtain an necessary number of bodies to be counted accurately by sucking the bodies into holes in the external circumference of a rotating cylinder at the negative pressure in the cylinder, and ejecting them at high pressure after the bodies are counted by the necessary quantity. CONSTITUTION:A cylindrical drum 1 has small holes 2a1-2an,-, 2f1-2fn corresponding to rooms isolated by bulkheads 14a-14f of a distributing trough 13, and rotates as shown by an arrow F. Parts to be measured are supplied into the respective isolated rooms from a hopper which is not shown in the figure, and negative pressure is produced in the drum through a vacuum suction pipe 7. The drum 1 while sucking parts to be measured into the respective small holes rotates; once quantity detecting means 30a-30f count up to a prescribed number, the negative pressure is released and high pressure is applied from a high pressure blow-off pipe 8 to allow the parts to fall in hoppers 24a-24f, thus storing them in a receiving disk which is not shown in the figure. Sequences (a)-(f) of parts to be measured are selected freely in terms of kind and quantity. Thus, various parts are taken out accurately.

Description

[Detailed description of the invention] The present invention relates to solids counters.

Nowadays, instant foods such as miso soup and ramen can be easily made by simply adding boiling water.
It is extremely difficult to pack gluten-free gluten, chikuwa-fu, etc. into bags in exactly the specified number of tubes because the number of pieces is relatively small (2 to 3 pieces), and the filling is done by hand, or the amount is measured without considering the number of pieces. The number of cylinders used is very variable. Regarding Jin, the more amorphous the shape, the more expensive it becomes, so it is not a good book.

The present invention aims to solve the above problems, and
An example of implementing the present invention will be described below based on the accompanying drawings.

The support shafts 15r, 17 and 1F1 are bracket plates for the support shaft 16. In addition, the 1st is a weir plate provided in the front position of the distribution trough, and its both ends are inserted into the grooves provided on both side wall plates of the trough, and it is moved up and down by holding the knob P from below. This allows the discharge height from the bottom of the top to be changed as appropriate. Further, the distribution trough is pivotally supported on a device frame (not shown) so as to be able to reciprocate over a certain width in the axial direction of the cylindrical drum l. The support shaft 20 is supported by a device frame (not shown), and the cough support shaft 20 is provided with a protrusion 21, and the support shaft 23 is parallel to the support shaft 20 and has a cylindrical cam 22 attached thereto.

When the cylindrical drum 1 rotates, the presence or absence of an object to be weighed that is suctioned and fixed to the through hole on the drum surface is discriminated and inputted to a counting counter and a controller (not shown), and the counting counter is controlled at a predetermined constant number. The vacuum suction action is released through the device. In addition, 32g, 326
, 32t @1111 are saucers placed in large numbers at a constant pitch on the belt conveyor 33, and the conveyor 3
When the cylindrical drum moves one pitch at a time with the intermittent rotation above 3, the cylindrical drum rotates by -1 in relation to the movement, and at this time one of the saucers comes to the lower position of the hopper 26. -ing

Next, I will explain the operation. First, a large number of objects 34 to be counted are put into the supply hopper 98. In this state, the electromagnetic feeder is driven, and the objects 34 to be weighed in the hopper 28 are quantitatively transferred. It is then thrown into the distribution trough 13. On the other hand, since the cylindrical drum 1 is rotated by the drive of a motor (not shown), at the same time, the inside of the cylindrical drum 1 becomes negative pressure due to the operation of the vacuum suction pipe, and the cylindrical drum 1 rotates upward from the lower surface of the distribution trough 13. The object to be counted 34 in the distribution trough 13 is suctioned and fixed to the through hole of the moving cylindrical drum 1.

In order to have a wide range of area in which the objects to be counted 34 in the distribution trough come into contact with the outer peripheral surface of the cylindrical drum 1, pull the knob P of the weir plate 18 downward. On the other hand, in order to stop it within a narrow range, the weir plate 18 is pushed upward.

In the apparatus of the present invention, while the rotating drum 1 is rotating, the objects to be counted 34 in the distribution trough 13 are inserted into the plurality of rows of through holes 2at, 2ax, 2416 m11.2 drilled in the outer peripheral surface of the drum.

For one rotation of the β weighing object 34, which is suctioned and fixed to each through hole, is inputted to the counting counter and the controller via the electric detection means of Son and Sob, and the When the number of objects to be counted reaches a required certain number, the vacuum suction inside the cylindrical drum is released, and all the remaining objects to be counted, which were suctioned and fixed to the surface of the cylindrical drum, fall into the export hopper 27. It is eggplant. It should be noted that the objects to be counted that are counted and thrown into the measuring cylinder pass through the hopper 26 at the lower end and are thrown into the respective receiving trays 32 directly below.

When the object to be counted 34 is an ingredient for instant miso soup, the type of object to be counted is dried fried rice, dried tofu, wheat gluten, etc., and these are placed in a saucer that moves intermittently as described above. Two, three, etc. are added exactly as needed.

Furthermore, in the above embodiment, the vacuum suction pipe and the compressed air blowing pipe 8 are separately installed in the cylindrical drum 1, but the nozzle pipes can be used for both by making them correspond to the number of through holes. Preparation 1 Normally, vacuum suction is performed, but a configuration may be adopted in which the solenoid valve is switched to a pressurized air blowout pipe by the combination of the detection means, and this is within the scope of the present invention. Other appropriate modifications and changes are free. In addition, in this embodiment, the distribution trough is made to move minutely back and forth in the axial direction of the cylindrical drum, since the objects to be counted in the distribution trough are not fixed to each other. On the other hand, it is superior in that it becomes easier to adsorb.

The device of the present invention is constructed as described above, and the object to be counted is suctioned and fixed to the surface of a rotating cylindrical drum, and the required number is counted and taken out by an electric detection means in the process of seven rotations. As a result, the required number of cylinders can be taken out accurately, and there is no variation in the number of cylinders to be fed, which is seen in the past.

In addition, even if the shape is irregular, it is possible to suction and fix it regardless of the shape, so it is possible to efficiently charge various solid materials at a constant rate, which greatly contributes to productivity improvement. It is a big thing.

In the above explanation, the objects to be counted are various types used in instant foods, but they can also be counted from various candies to mechanical parts such as screws and nuts.

It is conveniently used when packing a wide range of electrical parts and other items into constant bags. Note that the object to be counted is not limited to a solid object, and may be anything with a certain degree of soft viscosity.
