Description

[Detailed Description of the Invention] (a) Object of the Invention [Field of Industrial Application] The present invention relates to a device for taking out bread in a depanner for taking out bread from a food mold and aligning it upright after baking the bread. .

[Conventional technology]

In the bread making process, after the food mold containing bread dough is removed from the baking process, it is sent to a depanner, where the baked bread and the food mold are separated, and the bread taken out there is subjected to the appropriate processing or packaging process. A method is used in which the food mold is sent to the next process and returned to the section that accommodates the divided dough mass.

Conventionally, the method of removing bread from a food mold using the depanner described above is to invert the food mold fed into the depanner at the same place, and then drop the baked bread pulled out from the mold in an upright position onto the conveyor mounting surface. On the other hand, in the middle of transferring the bread to the next process, a step is provided on the conveyor placement surface, and when the bread conveyed between the steps is transferred, it is sequentially overturned by 90 degrees on the placement surface. Methods have been adopted, such as transporting bread that is pulled out of a mold while standing upside down and then held upright.

Figures 3 and 4 show an example of a method for taking out baked bread from a conventionally used depanner, and Figures 3a and 3b respectively show the drum 1 that holds the food mold 3 of the depanner. These are front views, and there is a difference between the two views in that the phase of the drum 1 is different from each other by 180°.

In Fig. 3a, (a) the food mold 4 containing the baked bread A is placed on the belt conveyor 9 and fed into the inner lower notch 2 of the drum 1 with the bottom of the food mold facing down. Although not shown, it also serves to push out the empty food molds stored in the notch 2 from the drum 1 onto the next conveyor 12 (see Figure 4a).

(b) In this state, drum 1 rotates 180 degrees in the direction of the arrow. At this time, the conveyor belt 16 is rising, and the baking bread placement surface of the belt is raised by the rotation of the drum 1 and faces the lower opening of the food mold 4, which is in an upright position. Baked bread A is blocking the mold and trying to pull it out from the food mold 4.
supports the top surface of the

(c) Referring to Fig. 3b, the belt conveyor 16 that was supporting the top surface of the bread A is lowered in the direction of the arrow as a whole, and the carrying surface remains supporting the top surface of the bread A. When it is separated from the mold 4, it remains at a position where the lower bottom (in the illustrated case, the upper edge) of the bread A and the open edge of the food mold 4 are slightly engaged.

(d) Figure 4a is a schematic side view of an example of a conventionally known depanner, in which the belt conveyor 16 is in a state where the bread A is supported on the mounting surface as described in section (c). Then, the bread A is tilted to the right in the direction of the arrow from the horizontal position, and is disengaged from the food mold 4 and placed on the surface of the conveyor 16. At this time, the bread A rolls on the surface and falls in the direction of the arrow. It should be rotated 90° on the conveyor mounting surface so that its top surface faces opposite to the direction of transport of the conveyor belt 16.

(e) As shown in Fig. 4b, the conveyor belt 16 moves in the direction of the arrow (to the right) with the bread A on it, and the bread A is received on the placing surface 16'' between the steps 16'. When transferring bread A', the bread A' is rotated 90 degrees in the direction of the arrow, and eventually the bread A'' is returned to an erect state on the conveyor placement surface 16'' and is conveyed to the belt conveyor 20 for the next process.

This method of removing bread is used.

By the way, in the above method, as expected from the steps described in paragraphs (d) and (e), sufficient measures are not taken to control the posture of the sampled bread. If the orientation and spacing of the breads A on the top are uneven, product defects and troubles are likely to occur before or after being transported to the next process.

(2) Especially when taking out mountain-shaped bread, the products tend to fall over and overlap, which can damage the products.

The occurrence of such troubles could not be avoided.

[Problem that the invention seeks to solve]

Therefore, the present invention solves the problems of the above-mentioned conventional technology, and prevents the products from falling over or overlapping by adding a simple mechanism in the process of removing bread from the food mold in the depanner, thereby preventing product value from being damaged. It is an object of the present invention to provide a device that can take out bread in an upright position, align it, and convey it.

(b) Structure of the invention [Means for solving the problem] In order to achieve the above-mentioned object, the method of the present invention has the following features:
It has the following configuration requirements.

(1) A position where an inverted bread is pulled out from a food mold that is engaged with a depanner drum that is intermittently driven around an axis provided substantially parallel to the food mold transfer direction, and a position where the pulled out bread is moved to the depanner drum. The bread extracted from the food mold is received in the receiving box as it is by communicating with the conveyor belt surface carried out from inside, and is rotated 180 degrees around the central axis provided independently from the depanner drum. A depanner characterized in that a mechanism is provided to release and deliver the bread that has been inverted and received in the bread receiving box onto the conveyor belt surface, and to align the breads in an upright state on the surface of the conveyor conveyor. A device that takes bread out of a food mold.

[Effect]

Case stands for holding food molds were cut out at symmetrical positions on the inner peripheral surface of the depanner drum, which was provided to rotate intermittently at 180° increments, and when the drum stopped, the bread pushed into one of the case stands was accommodated. After clamping and fixing the food mold, the drum is stopped rotating 180 degrees, and the bread housed in the inverted food mold is opened opposite the mold, and is rotatably supported on a frame separate from the drum. Drop the bread in the opposite direction into the bread receiving box.

Close the opening/closing plate of the receiving box that received the bread, hold the received bread so that it does not fly out of the receiving box when the receiving box rotates 180°, and then flip the receiving box 180° in one operation. The bread is stopped, the opening/closing plate is opened, and the bread in the receiving box is dropped onto the conveyor mounting surface for the next process in an upright state, that is, with the bottom facing down.

During that time, the empty food mold rotates 180 degrees and returns to its old position, where it is no longer clamped between it and the case stand, while the food mold containing the next bread is moved towards the same case stand. As it is pushed in, it is ejected from the case stand of the depanner drum, placed on another conveyor, and sent out of the machine.

Through the series of steps described above, one cycle of the method for taking out bread from a food mold using the depanner of the present invention is completed.

The case stand of the drum is equipped with claw clamps for holding and fixing the food mold, but when the case stand occupies the bottom position, the food mold containing bread is completely attached to the drum case stand. The claw clamp is open until the bread is fed, and therefore, the empty bread mold that was occupying the case stand is transferred to the drum by the new bread storage mold that is sent from the conveyor to the case stand. It is now possible to push it out and eliminate it.

〔Example〕

1 and 2 show an embodiment of the apparatus of the present invention. FIG. 1 is a schematic front view of the depanner drum, and FIG.
The figure is a side view of the depanner, and in the figure, 1 is
A case stand 2 is formed by providing a notch on the inner surface of the depanner drum symmetrically with respect to its central axis and along the generatrix direction, and claw clamps 3 are provided on the drums on both sides of the stand 2. When the case stand 2 occupies the lower position L, it is opened, and when it is at any other position, the food mold 4 on the stand 2 is always clamped to fix and hold the food mold 3 on the stand 2.
The drum 1 is supported by a pair of support rollers 5 on the lower side of its outer periphery, on which it is rotatable but restrained in the direction of the rotational axis, and concentric circles are formed along the outer periphery of the drum 1. A chain 8 is installed on the attached sprocket 6 via a sprocket 7 of a separately provided drive mechanism, and the drum 1 is rotated intermittently every 180 degrees by the drive mechanism. At this time, the rotation of the drum 1 is controlled so that the case stand 2 provided on the inner wall of the drum always occupies the low position L or the high position H and stops.

In Fig. 2, reference numeral 9 denotes a belt conveyor that intermittently feeds blocks of bread-containing molds 4 from the previous process to the case stand L position of the depanner drum 1. A stopper 10 for feeding out mold blocks one set at a time is provided so as to appear and retract. The conveyor is operated to convey the food mold blocks in the direction of arrow a.

Reference numeral 11 denotes a roller conveyor for receiving blocks of empty food molds 4 also pushed out from the case table L position and delivering them to the empty food mold collection belt conveyor 12, which are rotatable parallel to each other. A plurality of pivotally supported roller groups are arranged in an inclined manner, and the case table L position and the starting point position of the conveyor 12 are connected. The conveyor 12 is constantly operated in the direction of the arrow.

In FIGS. 1 and 2, 13 is a pan reversing mechanism, which is provided inside the drum 1.
They are provided in a vertical plane that includes the rotational center line of the drum 1, parallel to the axis, and symmetrical to each other with respect to a rotating shaft 14 that is rotatably supported on another machine frame. A bread receiving box 15 opens upward directly below the case platform height position H, and an opening faces downward to the placement surface of the bread conveyor belt conveyor 16, which is provided with at least a portion extending inside the drum 1. a bread receiving box 15' located at a position of 180 degrees with respect to the receiving box 15; a pair of double-opening opening/closing plates 17 each having a swing axis parallel to the rotating shaft 14;
17', and the opening/closing plate 17 receives the food mold 4 stopped at the case stand H position into the bread receiving box 15 in the opposite direction, and then closes it, and the receiving box 15 rotates around the rotating shaft 14. In addition to preventing the stored bread from falling out of the box even if the bread is stored in the bread receiving box 15' in the previous process, it is placed opposite the conveyor 16 placement surface while being held by the opening/closing plate 17'. The opening/closing plate 17' that engages with the bottom of the bread that has been reversed and transferred to the position is released, and the bread is gently dropped onto the conveyor 16 mounting surface in an erect state. Therefore, the bottom surface of the bread receiving box 15 of the reversing mechanism 13 needs to be at least farther away from the open edge of the food mold occupying the H position than the length of the amount of bread to be handled. The distance between the open edge and the placing surface of the conveyor 16 must also be greater than the length of the bread, but if the distance is longer than necessary, there is an increased chance of damaging the bread when it is discharged. This is not a desirable situation because it may disturb the alignment of the bread after it falls, or it may increase the overall capacity of the device.

A sprocket 18 is attached to one end of the rotating shaft 14 of the reversing mechanism 13, and a chain belt 19 is installed between the sprocket 18 and the sprocket provided on the drive mechanism described above, so that the drum 1 can rotate 180 degrees. At the same time, the reversing mechanism 13 is also provided to rotate intermittently through 180 degrees. From the perspective of the work process, it is preferable to start the intermittent rotation of the reversing mechanism 13.
Slightly faster than that of drum 1.

In addition, until the bread-containing food mold 4 sent to the L-position case table of the drum 1 reaches the H-position and the bread is dropped into the bread receiving box 15 in an inverted state,
Since the timing is set such that the opening/closing plate 17 of the reversing mechanism 13 is opened, the bread stored in the bread receiving box 15' in an upright position is also supported and received by the opening/closing plate 17' until that time. It will be waiting inside the box 15'.

Bread is stored in a receiving box 15, and its opening/closing plate 17
is closed and the bread is secured in the receiving box 15, and at the same time the opening/closing plate 17' of the receiving box 15' is opened, and the upright bread waiting in the receiving box 15' is placed on the conveyor 16. drop it on the surface. The reversing mechanism 13 intermittently rotates 180 degrees in one operation while maintaining this state, thereby reversing the positions occupied by the receiving box and the opening/closing plate, in preparation for the next cycle.

The upright breads that have fallen in line on the bread delivery conveyor 16 are transferred to the outside of the depanner, transferred to the conveyor 20, transported in the direction of arrow c, and transferred to the next process.

The operation of the depanner having the above configuration is as follows.
The main parts of the depanner drum and reversing mechanism are omitted as they are as explained in the section above.
Since it is operated only by rotational motion and no other complicated motions are added, there is room to increase the speed of operation as needed, enabling efficient depanner operation. Further, unlike known methods, there is no need for means for swinging the entire transport conveyor mechanism and the accompanying power consumption.

(C) Effects of the Invention The feature of the device of the present invention is that the bread is inverted by the depanner and removed from the food mold in an inverted state, and then stored in the receiving box, and then the receiving box is removed in one operation.
The bread is turned 180 degrees so that it is taken out onto the conveyor in an upright state and aligned.

According to the method of the present invention, by simply inserting a simple reversing and transferring mechanism between the depanner and the bread delivery conveyor, not only square bread but also mountain-shaped bread can be processed efficiently, automatically, and continuously. The products can be separated from the food mold, aligned and arranged on the mounting surface of the conveyance means without disturbing the interval, and can be conveyed to the next process without falling over or damaging the product.

Furthermore, compared to a conventionally known device for taking out bread from a depanner mold, the space and bottom area occupied by the device can be significantly reduced, and the device can be incorporated into a bread making line as is.

The present invention produces special functions and effects that cannot be expected from conventional techniques.
