DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fry frame reversing device for a fryer capable of reversing the material being fried in an oil tank and uniformly finishing both surfaces of the material.

[0002]

2. Description of the Related Art Generally, frying such as frying is continuously fried by a fryer equipped with automatic conveying means.

[0003] Flyers generally have a vertically long oil tank,
The material input from the upstream side of the oil tank is conveyed to the downstream side via automatic conveying means, and during this time, an appropriate frying process is performed. The automatic conveying means at this time includes, for example, a pair of left and right conveying chains and a number of lifting frames rotatably mounted between the conveying chains, and by driving the conveying chains, the material in the lifting frames is removed. It can be transported at a predetermined speed.

[0004] A lifting frame reversing device is provided in the middle of the transport chain. That is, a short rack is arranged in parallel with the transport chain, and a small-diameter pinion that meshes with the rack is fixed to the support shaft of the lifting frame. As the fry frame advances through the transport chain, the pinion of the fry frame meshes with the rack, so that the fry frame can be reversed as it advances. In addition, the rack is set to a short predetermined size for rotating the frying frame by 180 degrees, a plurality of racks are separately arranged in the middle of the transport chain, and the frying frame is inverted a plurality of times during the frying process. It is also possible.

[0005]

According to such a prior art, the fry frame is inverted during its operation by the pinion meshing with the rack. At this time, the mechanical relative movement between the rack and the pinion is increased. If the relationship is out of order, there is a problem that the meshing of the two cannot be performed smoothly, and the accident of losing the teeth of the rack or the pinion or damaging the spindle of the lifting frame is inevitable. In addition, for example, in a frying fryer for frying, it is not rare that the entire length of the oil tank exceeds 20 m, so that the elongation of the transport chain cannot be ignored.
Racks and pinions have a relative relationship that tends to be out of order.

Accordingly, an object of the present invention is to solve the problem of the prior art, and to provide a hook arm that mechanically engages with a hook pin of a lifting frame, so that the transport chain can be extended. Another object of the present invention is to provide a fry frame reversing device in a flyer that can always smoothly reverse a fry frame.

[0007]

According to the present invention, there is provided a lift frame rotatably mounted between a pair of transport chains via a support shaft on both sides, and a support for the lift frame. It consists of a hook pin protruding parallel to the axis, and a hook arm that can swing up and down that is arranged corresponding to the hook pin,
The gist of the latch arm is to engage the latch pin and invert the lift frame when the lift frame advances through the transport chain.

It is to be noted that a pair of locking pins can be provided so as to sandwich the support shaft.

Further, a guide rail for supporting the lifting frame can be provided downstream of the hanging arm.

[0010]

According to the structure of the present invention, the lifting frame can be driven from the upstream side to the downstream side of the oil tank by being driven via the transport chain. At this time, when the latch arm is engaged with the latch pin during the progress, the latch pin is restrained by the latch arm and can generate a rotational moment about the support shaft with respect to the lifting frame. it can.
That is, the lifting frame can be rotated around the support shaft and inverted by the rotational moment. In addition, when the lifting frame rotates, the latch pin also pivots about the support shaft, so that the relative distance to the latch arm changes, but this change in distance is absorbed by the swing of the latch arm. You. It is assumed that the hanging arm is automatically separated from the hanging pin when the lifting frame is inverted.

When a pair of hook pins sandwiching the support shaft are provided, even if the lifting frame is inverted, one of the hook pins moves to a position corresponding to the other hook pin before the inversion. By arranging multiple hanging arms along
The fry frame can be sequentially and repeatedly inverted.

If a guide rail is provided downstream of the hook arm, the guide rail can correctly regulate the posture of the lift frame after the inversion.

On the upper part of the oil tank 10, a transport chain 20,
A pair of guide rails 17, 17 are provided to horizontally support the lifting frames 30, 30,... Corresponding to the upper part of the 20 (FIGS. 2, 3). Further, a plurality of guide rails 42 are provided inside the oil tank 10 in order to horizontally support the lifting frames 30, 30... Corresponding to the lower portions of the transport chains 20, 20. However, each guide rail 42 includes a pair of square members 42a, 42a, and a pair of square members 42a, which extend from the downstream side of the deep bottom portion 11a of the oil tank 10 to the immediately upstream side of the hooking arms 41, 41 in the next deep bottom portion 11a. 42a is combined with a rod 42b connecting the upstream end (FIG. 1).

The hook arms 41, 41 provided at each deep bottom portion 11a of the oil tank 10 are provided with a through shaft 41a traversing the oil tank 10.
It is attached to be able to swing up and down through. Each hook arm 41 forms an upward hook 41b at the tip,
The boss 41c protrudes from the boss 41c that is rotatably fitted to the through shaft 41a. The weight 41 is attached to the boss 41c.

It can be positioned at a height of 1. The bosses 41c and 41c are set colors 41e and 4c, respectively.
Positioned on the through shaft 41a via 1e, the latching arms 41, 41 are positioned so as to correspond to the latching pins P1, P1 on both sides of the lifting frame 30.

When the transport chains 20, 20 are driven in the directions of arrows K1, K2 in FIG. 2 by a driving device (not shown), the lifting frames 30, 30,... Can be simultaneously circulated in the same direction. Therefore, if the material is put into the frying frames 30, 30,...
The materials in 0, 30,... Are fried by the frying oil in the oil tank 10 and can be taken out downstream of the oil tank 10. In FIG. 2, lids 32, 32,... Of the lifting frames 30, 30,... Turned back to the upstream side are open, and the lids 32, 32,. And

The fried frames 30, 30...
At the upstream end of the oil tank 10, it wraps around the oil tank 10 and proceeds downstream in the oil tank 10. At this time, each fried frame 30
In the deep bottom portion 11a, the locking pins P1, P1 are restrained by engaging the locking arms 41, 41 with the locking pins P1, P1 on the front side in the traveling direction from the lower side (FIG. 2). 4).

On the other hand, the square members 42a of the guide rail 42 for horizontally supporting the lifting frames 30, 30,... Do not exist at the positions of the locking arms 41, 41. As P1 and P1 are restrained and continue to move forward by the transport chains 20, 20,
As a whole, it is smoothly rotated in the traveling direction (the direction of arrow Ka in FIG. 4, the two-dot chain line in FIG. 2). At this time, each hook arm 41 swings around the through shaft 41a in the direction in which the hook 41b side is pushed down (the direction of arrow Kb in FIG. 4).

As described above, when the fry frame 30 rotates about 90 degrees (FIG. 5), the upper surface of the fry frame 30
2 is in contact with the bar 42b at the tip of
When 0 and 20 proceed further downstream, the rod material 4
2b further rotates the fry frame 30 relatively. Then, while the latch pins P1, P1 disengage from the latch arms 41, 41, the lifting frame 30 is reversed at a stroke, and thereafter is guided by the guide rails 42 and proceeds downstream.

Thereafter, the hanging arms 41, 41 return to their original postures with the weights 41d, 41d lowered, and the lifting frame 30 which subsequently proceeds to the deep bottom portion 11a can be inverted in the same manner. . On the other hand, in the fry frame 30 which has been turned over and rotated by 180 degrees, the positions of the pair of hook pins P1 and P1 on both sides are exchanged, but the hook pins P1 and P1 are
Since they are projected at symmetrical positions sandwiching a, the relative relationship between the latching pins P1, P1 after inversion and the corresponding latching arm 41 is exactly the same as that before inversion. Therefore, the lifting frame 30 is provided at the next deep bottom portion 11a with a hook arm 41,
The latching pins P1, P1 on the front side in the traveling direction are temporarily restrained via 41 so that they can be reversed again. That is, when the frying frames 30, 30,... Advance in the oil tank 10, the deepening portions 41a are repeatedly inverted by the hooking arms 41, 41 disposed on each of the deep bottom portions 11a, so that the inner material is uniformly distributed. Can be finished.

[0028]

Other Embodiments The frying frame 30 can be arbitrarily deformed according to the material to be fried (FIG. 6).

Here, circular storage portions 34a, 34a are formed by combining a pair of frame members 34, 34, and the storage portions 34a, 34a are openably and closably covered by a wire mesh. Further, arm-shaped side plates 33, 33 are fixed to both ends of the frame members 34, 34. Each side plate 33 is provided with a support shaft 33a and locking pins P1, P1. The side plates 33, 33 are twisted by an angle θ with respect to the horizontal direction H of the storage portions 34a, 34a, so that
Can be restricted in the direction of the arrow Ka in FIG.

In the above description, the hook pins P1, P1 projecting from the respective side plates 33 of the lifting frame 30 do not necessarily need to be provided at exact symmetric positions sandwiching the support shaft 33a. Each time the lifting frame 30 is inverted, the hook arms 41, 41 disposed on each deep bottom portion 11a have their lengths so as to smoothly engage with the hook pins P1, P1 located on the front side in the traveling direction. This is because it can be dealt with by alternately changing the length.

In each of the above embodiments, the locking arms 41, 41 are provided with the bosses 41c, 41c on the through shaft 41a.
Is moved to a position where it does not engage with the retaining pins P1, P1, so that the inversion of the fry frame 30 can be stopped. It is possible to arbitrarily set the number of reversals of the frying frame 30 during frying according to the type of the material.
The setting of the number of inversions can also be realized by making the through shaft 41a detachable, thereby temporarily removing the hook arms 41, 41 together with the through shaft 41a. That is, the frying frames 30, 3
If it is sufficient to invert 0... Once only, the latching arms 41, 41 may be provided only at one location of the oil tank 10.

The hook arms 41, 41 may be urged upward by a suitable spring member instead of the weights 41d, 41d. When the width of the oil tank 10 is small and the frying frame 30 is small, the catch pin P1,
P1 and the latch arm 41 need only be provided on one side of the fry frame 30. Further, in this case, the locking pins P1, P
1 is distributed and protruded on both sides of the fry frame 30, one for each
The hooking arms 41 may be alternately arranged on either the left or right side for each deep portion 11a.

[0033]

As described above, according to the present invention, a locking pin is projected from each lifting frame rotatably mounted between the transport chains, and a locking arm corresponding to the locking pin. With this arrangement, the latch arm restrains the latch pin of the moving lifting frame and generates a rotational moment on the lifting frame, so that the lifting frame can be smoothly inverted. The relative relationship with the arm is
Since there is no influence at all by the elongation of the transport chain, there is an excellent effect that even when a large oil tank is used, a smooth lifting frame reversing operation can always be realized.
