Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for continuously supplying and discharging real cans to a pressure cooker for sterilization in the canning industry.

(Prior technology) Conventionally, as a continuous heating pressure cooker,
The device described in Publication No. 11277 is publicly known, and this device is provided with an input device body and a take-out device body, which allow heated food to be taken out and put into the pot body by closing them at the input port and output port of the pot body. In order to enable air on the high temperature and high pressure side to be transferred to the other body when both bodies are closed, both bodies are connected to each other by a pipe.

(Problems to be Solved by the Invention) The conventional continuous heating type pressure cooker described above has a casing that communicates with the main body of the pot through an inlet, and has an opening on the opposite side of the inlet, and an article inlet having an opening. The main body is fitted into the casing, which communicates with the pot main body through the carry-out port, and has a take-out port on the opposite side of the carry-out port. The outlet of the extractor body is alternately communicated with the inside and outside of the pot body by rotating both bodies,
This is for receiving and transporting heated foods.
When the charger body and the extractor body communicate with the pot body, high-temperature, high-pressure air that has flowed from the pot body into the charger body or the extractor body is released to the outside when each body is opened, and heat is generated. This causes a loss of pressure, so
To prevent this, the injector body and the extractor body must be connected by a pipe equipped with a pump, valve, etc. in order to transfer high-temperature, high-pressure air from one side to the other when both are closed. The dot was hot.

The present invention has been made to solve the above-mentioned conventional problems, and includes:
A sliding shaft with two sets of actual can storage pockets is fitted to enable sliding and rotation, and by sliding, the two sets of storage pockets are alternately positioned in the pot, and by rotation, the cans are inserted into the pot. By simply providing a seal ring between each receiving pocket, and providing a bearing portion having a width that engages one or more of the seal rings on both sides of the inlet portion and the outlet portion, the inlet portion and the outlet portion It is an object of the present invention to provide a continuous supply and discharge device for actual cans for a pressure cooker that can completely prevent leakage of steam.

(Means for Solving the Problems) The means of the present invention for achieving the above-mentioned object is to provide a pressure cooker with an inlet and an outlet of a real can communicating with the pressure cooker, and to connect these inlet and outlet, Sliding shafts having a length equal to or greater than the double width are fitted so as to be slidable to the left and right, and two sets of real can storage pockets separated by seal rings are formed on these sliding shafts. an operating means for alternately positioning the two sets of real can storage pockets inside and outside the pressure cooker by sliding each one on a moving shaft in the left and right directions;
Each of the pockets is rotated by a predetermined angle in conjunction with a rotating means for changing the opening of the pocket into a state for receiving actual cans and a state for discharging actual cans. A continuous feeding and discharging device for real cans for a pressure cooker is provided with a bearing portion having a width that constantly engages one or more of the following.

(Function) The device configured as described above accommodates real cans from the opening into a set of real can storage pockets located outside the entrance of the sliding shaft that passes through the entrance, and this set of storage pockets is located outside the entrance. When the sliding shaft is slid toward the
One or more of the seal rings provided between each storage pocket always engages with the bearing part to maintain airtightness, so the storage pockets of the set containing actual cans can be closed at the entrance without leaking steam. is located in
Since the other set of storage pockets are located outside the entrance, in this state, if the sliding shaft is rotated by the rotating means and the opening of the actual can storage pocket is directed downward, the inside of the storage pocket will be opened. The fruit cans are sent to the conveyor.

Therefore, if you rotate the sliding shaft so that the opening faces upward, store the actual cans into a pair of storage pockets located outside the entrance, and then slide the sliding shaft in the opposite direction after storing the cans. As described above, the sliding shaft positions a pair of storage pockets containing actual cans at the entrance part in a state where airtightness is maintained by engaging one or more seal rings and the bearing part, Since the set of storage pockets from which the actual cans were delivered are positioned outside the entrance, the sliding shaft is rotated accordingly to send the actual cans in the storage pockets to the conveyor and then returned to the storage pockets. Store the cans and move them to the entrance,
The operation of sending actual cans to the conveyor by rotation,
If this is done in synchronization with the progress of the conveyor, the continuous supply of actual cans will be reliably carried out in an airtight state.

When the cans are continuously supplied in this manner, the cans are conveyed through the pressure cooker by the conveyor for a predetermined period of time, during which time they are sterilized and reach the outlet. Therefore, when the previous sterilized real can falls from the conveyor into a pair of real can storage pockets on the sliding shaft passing through the exit section, the storage pocket at the entrance section is moved to the entrance section by means of reciprocating the sliding shaft. When the actual cans are ejected from one set of storage pockets, the cans are ejected from one set of storage pockets by rotating the storage pockets using the rotating means so that the openings of the storage pockets face downward. When the opening is returned to face upward, the storage pocket located within the inlet section will receive the actual cans that fall one after another from the conveyor. Therefore, when the storage pocket receives the cans, the sliding shaft is slid in the opposite direction, and the set of storage pockets located at the entrance are positioned outside the entrance, and after the cans in this storage pocket are discharged, put it back,
If the operation of dropping cans from the conveyor into a set of storage pockets located in the entrance section is carried out in synchronization with the progress of the conveyor, continuous discharge of cans can also be carried out reliably in an airtight state. It is.

(Effects of the Invention) The continuous feeding and discharging device for real cans for a pressure cooker according to the present invention has two sets of real can storage pockets at the inlet and outlet of the real cans attached to the pressure cooker. The two sets of storage pockets are alternately positioned at the entrance or exit and on both sides thereof by passing through the cans and sliding the sliding shaft, and on the entrance side, the actual cans are placed in the storage pockets located outside the entrance. When the storage pocket moves to the entrance, the sliding shaft is rotated to tilt the storage pocket to send the actual cans to the conveyor, and on the exit side, the cans are sent to the storage pocket located at the exit. When the cans are sent out from the conveyor and the storage pocket moves outside the outlet, the sliding shaft is rotated and the cans are sent out by the tilt of the storage pocket, so the pressure of the sealed type is Not only can it be possible to continuously supply and discharge actual cans to and from the pot while maintaining its airtightness, which can save labor, but the pressure cooker mentioned above can be kept airtight by using the sliding shaft. This can be completely achieved by a very simple structure in which a seal ring is provided between each of the can storage pockets, and the bearing portion of the sliding shaft is formed to have a width that allows one or more of the seal rings to engage at all times. As a result, equipment costs are greatly reduced and the cost of sterilizing canned goods is significantly reduced.
