Description

Detailed Description of the Invention (Industrial Application Field) The present invention is used in the bagging or canning process of foods such as curry and stew, for example, in which solid materials such as meat, diced beans, potatoes, and carrots are packaged in cans or canned. The present invention relates to a solid material feeding device that can be applied to automatic canning machines, automatic bagging machines, etc. that feed into filling containers such as bags.

(Prior art) Conventionally, a measured or arbitrarily determined amount of the material to be filled is stored in a container, and only the material to be filled in the stored container is processed using a separately prepared automatic canning machine or automatic bagging machine. When discharging and filling cans or bags, if the container is simply turned over and the material to be filled is put in, the material to be filled will adhere to the inner wall surface of the container, ensuring that a predetermined amount of the material to be filled is put in. There was a drawback that I couldn't do it.

(Problem to be Solved by the Invention) Conventionally, as a countermeasure to this problem, by inverting the container and dropping it so that it contacts the stopper, the material to be filled that has adhered to the inner wall surface of the container and has not fallen naturally has been removed by contacting the stopper. A filling device has been proposed in which the material is peeled off by the impact force upon contact and placed in a can or bag, but in the case of light weight materials or flat-shaped materials, the material may still adhere to the inner wall of the container. There was a risk that it would remain.

(Means for Solving the Problems) The present invention has been proposed to solve the above-mentioned conventional drawbacks, and consists of a pair of fixed disks installed at a predetermined interval, and a solid material placed in the center of one of the fixed disks. A supply hole for a container filled with a material to be filled, etc., is provided in the center of the other fixed disk opposite to the same supply hole, and a discharge hole for an empty container is opened in the center of the other fixed disk, facing the supply hole of the fixed disk. Connect the supply device of the container filled with the material to be filled,
A discharge chute for an empty container is connected facing the discharge hole of the fixed disk, and a rotatable rotor is disposed between the fixed disks, and the rotor is attached to a rotating shaft and connected to the discharge chute of the empty container. a square block that supports the bottom of a container supplied from the same square block; a pair of guide brackets that are attached to the same square block and extend parallel to each other within a fixed disk and slide and guide the supplied containers;
It consists of a receiving plate that is provided at both ends of the bracket and has a discharge hole for the material to be filled in the supply container, and the material to be filled in the container is discharged downward by the rotation of the rotor every 180 degrees. It is an object of the present invention to provide a solid material input device characterized in that when a new container is supplied, an empty container is pushed out from the new supply container to a discharge chute.

(Function) When the actual container is pushed into the rotor by the container extrusion device, and then the rotor rotates 180 degrees, the actual container is reversed as the rotor rotates and moves outward due to its own weight and centrifugal force, and the filled container inside is Items are placed inside cans, bags, etc. During the next 180 degree rotation, the empty container that has discharged the filling material balances centrifugal force and self-weight, and gradually returns to an upright state while contacting the arcuate part of the container guide. It is pushed out by the container and received into the discharge chute.

The stopper 7 is activated by the number check signal of the phototube 8.
acts to supply and stop the subsequent actual containers 3.

When the actual container 3 is at position A in FIG. Return to position.

Next, when the rotating shaft 26 rotates 180 degrees in the direction of the arrow B in FIGS. 1 and 3, the container take-out device 10 also operates to bring the next actual container 3 into contact with the guide member 16 and take it out to position A. On the other hand, the actual container 3 at position B is inverted as the rotor 12 rotates and moves outward by a distance L (Fig. 3) due to its own weight and centrifugal force, and at the same time comes into contact with the buffer member 33 on the receiving plate 31. ,
The material to be filled 2 is placed into a pouch 50 that is transferred in the direction of arrow C in FIG. At this time, while the rotor 12 is stopped, the pusher 19 operates to push out the next actual container 3 from position A to B in the same manner as described above.

Next, when the rotating shaft 26 rotates 180 degrees again in the direction of arrow B, the actual container 3 at position B is reversed in the same manner as described above and the material to be filled 2 is thrown into the next pouch 50. On the other hand, the empty container 3a from which the material to be filled 2 has been discharged as described above
During the 180 degree rotation, the container gradually returns to its erect state while bringing its upper end into contact with the arcuate portion 60 of the container guide 45 by balancing the centrifugal force and its own weight as shown in FIG. Finally, it is placed at position B.

Next, while the rotor 12 is stopped, the pusher 19 operates to push the actual container 3 toward the rotor 12, and the empty container 3a at position B is pushed out by the actual container 3 and moved to position C as described above. do. However, at position C as shown in FIG. 2, the empty container 3a is reversed in the direction of arrow D, reaches position D, is accommodated in the container discharge chute 47, and is transferred to the conveyor 54 while rotating within the chute 47. Guided to the process.

By repeating the above operations, the material to be filled 2 is sequentially and intermittently transferred to the pouch 50 that is conveyed from the pouch supply section 55 (of course, operations such as pouch removal, opening forming, and solid material input are synchronized with the present solid material input device 6). and then sequentially operate). Note that by adjusting the rotational speed of the rotor 12 and the reversal movement distance L of the actual container 3 according to the conditions of the material to be filled 2 (weight, shape, etc.), the material can be reliably charged into the pouch 50.

(Effects of the Invention) Since the present invention is configured as explained in detail above, the impact force when the actual container comes into contact with the receiving plate is increased, and the container is not adsorbed to the inner wall surface of the container and falls by itself. The material to be filled can also be reliably peeled off and a predetermined amount of material to be filled can be reliably put in, and the rotor is attached to a rotating shaft and has a rectangular block that supports the bottom of the container supplied from the supply hole. , a pair of guide brackets attached to the same rectangular block and extending parallel to each other within a fixed disk for slidingly guiding the supplied container, and a pair of guide brackets provided at both ends of the brackets to form discharge holes for the material to be filled in the supply container. It consists of a receiving plate, and by rotating the rotor every 180 degrees, the material to be filled in the container is discharged downward from the receiving plate, and when a new container is supplied, the empty container is pushed out to the discharge chute by the same new supply container. This makes it possible to speed up the processing capacity, that is, double the conventional processing capacity.

In addition, the centrifugal force can be adjusted by adjusting the rotational speed of the rotor or the reversal movement distance L of the actual container, so it can fully respond to changes in the conditions of the material to be filled (light weight, shape, etc.), and is highly versatile. can be improved.

In the case of the natural fall method, in order to increase the impact force, it is necessary to increase the head, which requires a correspondingly longer fall time, and the capacity (filling speed) of the filling device gradually decreases. In the case of the present invention, since it uses a forced rotation drive system, it is possible to reverse the drop in a shorter time than when it falls naturally, and the impact force can be increased, and cup feeding and ejection can be performed at the same position. At the same time, the capacity of the filling equipment has been greatly improved (the conventional method was 30 cups/min, but this method has increased it to 100 cups/min).
minute). In addition, by installing a plurality of rows of container conveyors, container supply chute, solid material input device, etc., it is possible to easily create multiple rows and improve productivity.
