Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a retort oven device for automatically loading and unloading products to be sterilized into a retort oven.

When carrying so-called retort pouches, which are foods sealed in containers that do not allow light or air to pass through, into a retort oven to sterilize them by heating and pressurizing, it is recommended to install a conveyor inside the oven that circulates only inside the oven. In the past, rails were provided inside the kiln, and the receiving subgroup with the retort pouches arranged on it was mounted on a trolley outside the kiln, and the trolley was manually pushed onto the rails inside the kiln, and then the lid of the kiln was placed. was installed, and boiling water or heated, pressurized steam was injected into the kiln for sterilization.

Therefore, not only does it require manual labor, which does not improve efficiency, but the entire truck is exposed to heat and pressurized steam, which leads to disadvantages such as rusting of various parts such as the frame of the truck and severe deterioration of the lubricated parts of the wheels. was there.

The first object of the present invention is to save labor by automatically carrying retort pouches into and out of a kiln, and the second object is to save labor by automatically carrying retort pouches into and out of a kiln.
The purpose of the retort kiln device of the present invention is to prevent the carrying cart from being exposed to heating, pressurized steam, or hot water.
A retort pouch receptacle trolley pushing device is installed outside the kiln, and a trolley equipped with a pan lifting device is reciprocated between rails installed inside and outside the kiln independently and facing each other. This purpose was achieved by automatically lowering the receiving subgroup from the trolley onto the floor provided inside the vehicle, and by automatically moving the trolley out of the window.

As shown in FIG. 2, the retort oven body is installed with a distance K from the front end of the cart pushing device 3.

This involves transporting the retort pouch receiving subgroup into the kiln body using a trolley 7, and then removing the lid 2 of the helmet body to the position shown by the dashed-dotted line using a lid attaching/detaching device (not shown). This is the space required to further lift the lid to the position indicated by the two-dot chain line using a lid lifting device (not shown).

Similarly, Sq is the outlet of the kiln, and Sq is the base of the kiln body.

Function Next, the function of the retort fixing device of the present invention will be described. When the drive motor 20 is rotated, the sprocket wheel μ/g is rotated by the endless chain 2/, and the endless m/q is driven by the rotation of the sprocket wheels/O at both ends on the same shaft/7, and the roller/3 is rotated. Rotate. If the tray stack group IlB in which retort pouches are arranged is placed on the right end roller /3 of the saucer truck pushing device 3 shown in FIG. 7
It passes above and moves to the left, hits the stopper l17, and stops at the position shown by the dashed line in Figure 1.A separate receiver detects the arrival of the surface group B and stops the drive electric motor m20. let

Next, after moving the lid 2 of the retort main body/to the position shown by the two-dot chain line shown in FIG. 2, the pressure cylinder 3 shown in FIG. When driven, the stopper t17 rotates around the axis lIq and opens, and the receiver releases the stoppage of movement of the surface group B. When such support starts operating the off-board lowering electric motor 33, the drive shaft 35 rotates via the gear mechanism 3t, and the worm gear 3
9. Since the worm wheel shaft ll/ is rotated through the worm wheel I/O, the roller support arm 2 shown in FIG. As it is pressed upward, the receiver is guided by the lifting plate guide ll, l13,
It rises to a position a distance N from the upper surface of the truck 7, as indicated by the dashed line, and the drive motor 33 is stopped by the daytime position detection device. Therefore, the receiving surface group lI6 is the third
It rises to a position a distance p from the surface of roller/3 shown in the figure, supported by the elevating plate lll1, and floats off the surface of roller/3.

In this state, when the trolley drive motor 27 shown in FIG. 1 is operated, the sprocket wheel 30 shown in FIG.
! ;,,2 Push it to the left in the space surrounded by Otsu. Therefore, via the rust fixing fittings 23 and the cart driving fittings 22, the cart 7 carries the receiving subgroup Il O and moves to the left on the rail j1 O, and the cart 7 reaches the position shown by the dashed line in FIG. When the cart moves to the point where the wheels come off the chevron rails 5, the cart maintains its direction along the chevron rails due to the grooved wheels 9 and 10, moves forward further, moves to the chevron rails tp in the kiln, and finally moves to the position shown in 1st≠[. At this position, a separate truck arrival detection device is activated and the drive motor 27 is stopped.

Next, when the electric receiver pAJ3 is operated in the opposite direction,
The worm wheel IklIIIl/ rotates in the opposite direction (counterclockwise), and the roller support arm I1.2 and the support plate l1lI return to their original positions shown in FIG. At this position, a position detection device is activated separately, and the elevating motor 33 is
il, f rotation stops.

Therefore, the receiving surface group lI B shown in FIG. A gap Q is created between the upper surface and the upper surface. In this state, when the trolley drive electric motor Noah is operated in the opposite direction, the sprocket wheel 30 shown in FIG. Since it passes through the kiln and returns to the original position shown in FIG. 1, a separate cart position detection device is activated and the electric drive pA, 27 is stopped.

The retort pouch holder is completely attached to the kiln body in the state shown by the solid line in Figure 2, with the lid 2 of the kiln in the state shown by the solid line in Fig. 2, when the tray geIl B has been carried into the kiln body and the trolley 7 has been returned to the outside of the kiln. Then, close the discharge port jg, supply hot water or heated 11nm steam into the kiln from the supply port 57, heat sterilize the retort pouch for a predetermined time, then close the supply port, open the discharge port 3g, and supply boiling water or steam to the inside of the kiln. The heated and pressurized steam is removed from the kiln, and after the retort pouch has cooled, the lid 2 is moved to the position indicated by the two-dot chain line in FIG. 2, and the trolley drive motor 27 is operated again.
The cart 7 is moved to the position shown in FIG. 11I. After that, the receiver operates the electric motor 33 for unloading the container to raise the tray ≠ B in the kiln from the floor to the position shown at a point KM in FIG. When driven in the direction, the group of supports and faces are carried out of the kiln together with the trolley, and the sterilization work is completed.

All of the above continuous operations are automatically performed by an electric circuit that makes full use of a position detection device and a timer.

Effects Since the retort pouch device of the present invention is constructed and operates as described above, it is easy to carry the retort pouch receiving tray into the kiln.
Transport can be carried out efficiently without requiring any human labor. In particular, when carrying the tray into and out of the kiln, the tray is moved by floating the tray higher than the floor of the kiln.
There is no need to install a roller conveyor or the like for moving the trays in the tray placement section in the kiln. In addition, since the dexterity cart is not exposed to hot water or heated or pressurized steam, the receiver has the effect of making the equipment easier to maintain, and is a useful invention that can contribute to labor savings for the entire device.
