Description

Detailed Description of the Invention (a) Purpose of the Invention [Field of Industrial Application] The present invention provides an inversion type for automatically taking out bread from a food mold after baking it, aligning it upright, and carrying it out. This invention relates to a forced fall device for bread in a depanner.

[Conventional technology]

The bread-filled food mold loaded into the reversible depanner is intermittently rotated 180 degrees and turned upside down, and the bread is taken out from the mold in this state, and the bread is placed directly below the bread supported so that it can be turned over. After receiving and storing the bread in the receiving box, the receiving box with the bread stored therein is inverted 180 degrees in one operation, and the bread is discharged in an upright state onto the placement surface of a conveyance means provided below. The "method for removing bread from a food mold using a depanner" is easily implemented by a person skilled in the art, as described in the patent specification and accompanying drawings filed by the applicant as Japanese Patent Application No. 60-204399 prior to the filing of this application. Please disclose as much as possible. Further, at that time, the specific structure of the reversible depanner for implementing the above method is also detailed in the above specification and drawings.

By the way, in the above-mentioned apparatus, the means for extracting the baked bread from the inverted/inverted food mold is to apply a mold release agent to the inner surface of the food mold, and to reduce the adhesive force between the mold and the bread by applying the self-weight of the baked bread. If necessary, air can be blown between the wall of the food mold and the bread to promote separation, or the intermittent operation of the rotating drum can be used to control the food mold. It is designed so that by applying an impact, the bread will separate from the mold and fall under its own weight.

In this regard, the same method as described above is also adopted in the "Method for Removing Bread from a Food Mold in a Depanner" described in Japanese Patent Application Laid-Open No. 58-107130, which was published before the patent application for the above method was filed. It is understood that there are At least, no further technical disclosure has been made.

In the first place, the inner surface of the food mold expands upwards and is smooth, and the mold is coated with a release agent before filling the bread dough, making it easy to separate from the baking bread mold. Before releasing the bread from the mold, blow air between the inner wall of the mold and the bread to break the adhesion between them and turn the mold upside down.The bread will then be pulled out of the mold by its own weight. It is set up like this. Therefore, the above-mentioned method alone usually does not cause any particular trouble in removing the bread from the mold.

However, even in the past, when the weight of the baked bread is light, when the draft angle of the food mold is gentle, the adhesion force of the bread becomes large, and when the baked bread expands and sticks strongly to the food mold, there are cases where the bread cannot be released from the mold. There are various reasons for this, such as uneven application of the agent, bread expanding and covering the edges of the mold, and air not reaching between the mold surface and the bread even when air is blown. Additionally, there were cases in which the bread did not come out of the mold simply by inverting the mold. Therefore, in order to manually release the bread from the mold, the food mold is inverted or held upside down, and the corner of the mold is struck against a fixed object to give an impact to the baked bread, thereby reducing the adhesive force between the bread and the mold. It used to be cut off, but if you are not careful when doing so, the bread may end up on one side and come out, which can damage the product. In particular, it is said that there is a risk that the top of the mountain-shaped bread may hit something and cause damage to that part.

Even in the case of the above-mentioned "method of removing bread from a food mold using a rotary depanner," a method that exclusively utilizes the weight of the baked bread was used as a means of removing the bread from the food mold.・It cannot be said that there are cases where the bread does not come out of the mold even if the bread is turned upside down.

[Problems to be Solved by the Invention] For such bread-containing food molds, it is necessary to remove the food molds from the rotary depanner and while the food molds are transported from there to the empty mold reuse process. It is necessary to remove the remaining bread from the mold.In automatic equipment, if the operations in each process that make up the process are not carried out reliably and uniformly, subsequent processes may be hindered. Although the above-mentioned device can be used by inserting a process for removing baked bread residual food molds in the subsequent process of the depanner, it is not preferable if the automatic device does not reliably release the bread from the mold. In addition, it requires an extra monitoring system and post-processing process, which is disadvantageous in terms of cost reduction.

In particular, it is desirable from users to provide a device that is capable of always reliably separating the bread from the mold, no matter what mold is used and even when some of the aforementioned adverse conditions are present. This is a strong request.

Therefore, in order to solve the above-mentioned problems inherent in conventional devices and also to meet the strong demands of users, the present invention has been developed to remove bread from an inverted/inverted food mold using a rotary depanner. The object of the present invention is to provide a forced bread dropping device that can reliably separate and drop baked bread. Another purpose is to prevent the upper part of the bread from being damaged when the bread is pulled out of the mold and falls into the bread receiving frame. It attempts to provide a dropping device.

(El) Structure of the Invention [Means for Solving the Problems] In order to achieve the above object, the present invention includes the constituent elements described below.

+11 The table for holding the loaded bread mold holding case and the rotating drum are connected by a removable locking member or supported by a spring bias, and the table is equipped with a slider or a rotary drum. A rotating drum is provided with a trochanter, and the rotating drum is rotated intermittently in one direction to rotate the food mold, which is fixed to the case gripping table, 180 degrees at a time.
Before and after inversion/inversion, engage the slider or trochanter with the cam surface and release the locking member, or hold the case gripper while it is supported by a spring bias. A cam is used to cause an impact to be applied to the bread-containing food mold by reciprocating the bread-filled mold so that it suddenly moves downward from a fixed position or returns to a fixed position from a downward position, thereby separating the baked bread from the inverted food mold. A reversible depanner pan forced fall device.

(2) Due to the rotation of the rotating drum, before the slider or trochanter provided on the food mold holding case gripping base comes off the cam surface, the locking member works again to close the gap between the rotating drum and the case gripping base. The forced dropping device for a reversible depanner according to item (1) above, which is formed by connecting the device.

(3) A focal plane type opening/closing and conveying mechanism is installed between the food mold holding case gripping base and the bread receiving frame installed at a position opposite to the table, and the opening/closing and conveying mechanism is The forced fall of bread in the reversible depanner according to item +11 or item (2) above, which comprises closing the open surface of the bread receiving frame before the reciprocating cycle ends and the rotation of the rotating drum starts again. Device.

(4) The bread forcible dropping device for a reversible depanner according to item (1) above, wherein the gripping mechanism of the food mold holding case is a combination of a click-stop type positioning member and a spring-pressing locking member.

(5) A cushion plate is provided at a position opposite to the food mold holding case gripping base with respect to the focal plane type opening/closing and transporting mechanism, and a cushion plate is arranged on the bottom surface of the bread receiving frame having an opening on the opening/closing and transporting mechanism side. The forced bread dropping device for a reversible depanner according to item (1) above.

[Effect]

Figure 5 (al to te+) shows an overview of the overall operation of the device of the present invention, including the attached mechanisms, and only the operation of one side of the case gripping stand is shown, but the operation of the device will be explained according to the order of the figures. .

(al) The process of setting the bread-filled food mold holding case on the gripping stand of the rotating drum.
(See figure 2, hereinafter also referred to as the stand).
The case pushes out the empty food mold from the gripping table toward the food mold reuse process [see (e)], and at the same time,
The case is positioned with respect to the stand by a click stop mechanism, and at the same time, the push-up plate is lowered and the clamp mechanism, which has been opened, is biased by a spring, and the case is set on the stand.

At that time, the focal plane type opening/closing and bread conveyance mechanism located on the upper surface of the opening side of the food mold, which is locked to the gripping stand, is used to discharge the bread that has already been pulled out of the food mold out of the drum by the conveyance mechanism. After finishing (see (e)), the operation continues to pass through a state where the opening surface of the food mold is closed, and then it is driven to a position where the opening surface of the food mold is opened, and the operation is stopped there.

(bl) The process of inverting the food mold and taking out the bread When the rotating drum rotates 180 degrees intermittently with the gripping base locked, the food mold will also be reversed and turned upside down. The slides or trochanters provided on the case grip stand rest on upwardly convex cam surfaces (see numeral 22 in Figure 3) provided on both sides of the upper part of the rotating drum, and the weight of the stand, case, etc. is supported by the cam surfaces. At the same time, a separately provided cam surface (Fig. 3, reference numeral 1)
9) to open the mechanism that locks the holding table and the rotating drum.

By this time, the partition of the opening/closing and conveyance mechanism installed between the bread receiving frame and the food mold, which are installed facing the opening surface of the food mold, is open, so the food mold may be inverted or upside down. The baked bread, pulled out of the food mold by its own weight, falls and is stored upside down in the opposing bread receiving frame. At that time, the partition plate swings and enters into the bread receiving frame to occupy a position, and a thick, elastic member with appropriate elasticity is placed on the bottom plate of the receiving frame to prevent the falling baking bread from falling. Designed to avoid scratches on the surface.

However, the purpose of the above-mentioned cushion member is to prevent the baking bread, which falls forcefully into the receiving frame due to the operation of the forced bread dropping device described below, from being damaged.

Now, as mentioned earlier, there are some baked breads that do not release from the mold simply by inverting or inverting the mold. After the rotating drum rotates intermittently by 180 degrees and stops, the upward convex cam surface is connected to the air cylinder mechanism (Fig. 3, number 23).
- 25)) to apply an upward and downward impact to the gripping table, food mold, etc. on which the weight is applied, removing the baked bread that had remained in the mold until then. To break the adhesive force between a food mold and a food mold, and to surely release and drop the baked bread still attached to the mold even when the food mold is inverted, and store it in a bread receiving frame. The measures described above, however, also make it possible to implement the case gripping stand diametrically with respect to the rotating drum in a spring-biased manner. Note that the strength of the impact can be changed as necessary, such as by adjusting the stroke for moving the food mold up and down, or by adjusting the strength of the return spring pressure of the air cylinder.

(C) Opening/closing and conveyance mechanism operation process Once the bread has been removed from all the food molds and stored and arranged upside down in the bread receiving frame, the opening/closing and conveying mechanism provided opposite the open surface of the bread receiving frame is activated. Then, the screen-like member blocks the gap between the food mold and the receiving frame, and eventually closes the open surface of the bread receiving frame.

In this way, even if the bread receiving frame is tilted, the opening/closing and transport mechanism is stopped so as to cover the open side of the receiving frame so that the housed bread will not fall off or the alignment will be disturbed.

(dl Reversing process of the bread receiving frame In the middle of intermittently rotating the rotating drum 180 degrees, the gripping base and rotating drum are locked again by controlling the separately provided cam surface as described in the bl process. The mechanism works, and then the slider or trochanter attached to the gripping base moves away from the upward convex cam surface by the rotation of the 0-rotation drum, and the bread holder frame is rotated 180 degrees.
Since the loaf of bread is inverted and inverted, the bread housed in the receiving frame is erected and falls and is aligned on the conveying surface of the opening/closing and conveying mechanism.

At this time, the falling distance and falling speed of the bread are small, and the bread falls with its bottom side down, so there is no need to provide a cushion member to the conveying mechanism.

+81 Bread discharge process The bread that fell and was placed on the opening/closing and transport mechanism,
After the diaphragm of the bread receiving frame swings to open a path for the bread, the conveying mechanism is operated, and the bread is discharged from the opening/closing and conveying mechanism and the rotating drum toward the next process.

At the same time, the push-up plate works and the clamp mechanism releases the empty mold from the gripping base, and as mentioned above in the tal process, a new bread mold is carried into the stand of the rotating drum, thereby releasing the empty mold. Extrusion, ie, case replacement, is performed for the reuse process, and then a new food mold is clamped to the table.

In this way, the tal process and subsequent steps are repeated again.

The functions of the apparatus of the present invention are those described above exclusively in the first step.

〔Example〕

(Part 1) , ), Figure 1 shows a reversible depanner equipped with the device of the present invention.
), - is a schematic front view of one embodiment, and FIG. 2 is a side view, and in the figure,
1 is a rotating drum, 2 is a food mold holding case gripping stand installed close to the outer periphery/surface of the drum 1 and symmetrical with respect to the center of rotation, and a case gripping stand 7 of the same shape is installed on the opposite side. It is. Each member explained below is the case gripping base 2. Similar to r, all of them are arranged point-symmetrically with respect to the rotation axis of the drum 1, so only one structure will be explained, and the description of the other one will be omitted. 3 is a food mold holding case, in which multiple food molds are stacked in parallel and integrated and tightened with a band around the periphery; 4 is a bread receiving frame, and the receiving frame has an opening for each food mold. Corresponding to this, a plurality of partition plates 5 are installed on both sides which are swingably supported. 6 is a focal plane type opening/closing and pan conveyance mechanism consisting of a chain and a belt, and a plurality of pulleys and sprockets 7,
The chains and belts are constructed in a box shape, with a part of the chain and belt forming a curtain shape, and the other part being open, with the long side of the box facing the open side of the food mold. It extends to a position near the bread receiving frame between the installed bread receiving frames 4, and blocks the gap between the two, but depending on the opening/closing and driving conditions of the bread conveying mechanism 6, the open part of the belt may close between the food mold and the bread receiving frame. The layered belt moves and communicates between the two, and does not prevent the bread from being pulled out of the inverted/inverted food mold and falling into the bread receiving frame 4 directly below [see Fig. 5 (bl)]. The baked breads fall vertically upwards, and the baked breads lined up there are transferred by driving a conveyor, and then transported out of the rotating drum 1 via a group of 8 discharging rollers provided subsequently [Fig. 5 1dl +81
reference〕.

Note that the rotating drum l rotates intermittently every 180° around its central axis in the direction of the arrow.

Reference numeral 9 denotes a carry-in conveyor for the food mold holding case 3 provided on the side of the frame, the end of which is installed near the circumferential surface of the drum 1, corresponding to the stop position of the case gripping table 7.

Reference numeral 10 indicates a group of baking bread transport rollers on the frame side facing the ejection roller group 8, and reference numeral 11 indicates a group of rollers for carrying out the empty mold case 3. As mentioned above, the operation of the reversible depanner is the "action" mentioned above.
As detailed in the section above, the device of the present invention has the following features:
One of these machines is attached to both sides above the rotating shaft, and applies an impact upward and downward to the inverted/inverted food mold, forcibly pulling out the baked bread that had remained in the mold from the mold. The process of dropping and storing the bread in the opposing bread receiving frame 4 is performed (see the process shown in FIG. 5 or FIG. 1).

FIG. 3 is a schematic front view of the device of the present invention, and FIG.
It is a cross-sectional view along line VI'/, in which 1 is a rotating drum;
Reference numeral 2 denotes a case holding stand, which is guided by a plurality of guides 12 provided on the drum l and supported so as to be movable in the direction of the rotational axis of the drum. Reference numeral 13 denotes a support shaft provided upright on both sides of the case gripping base 2, which is always locked to the drum side by engaging with a locking plate 14 pivotally supported on the periphery of the drum 1 so as to be able to swing freely. The plate 14 is biased clockwise (in the locking direction) in the figure by a tension spring 15.

As mentioned above, the rotating shaft 16 of the locking plate 14 is supported by a bearing on the peripheral edge of the drum, and an arm 18 with a roller 17 is fixedly provided at one end of the arm 18. Accordingly, the arm 18 is engaged with and placed on the surface of the cam 19 provided on the side of the crosspiece frame, thereby causing the arm 18 to apply clockwise torque f,·ψ· based on the tension spring 15.

, - it swung counterclockwise, and ended up as shown in Figure 3.
゛The locking plate 14 is released from the support shaft 13, and the rotating drum l and the case gripping base 2 are uncoupled slightly earlier than that (the roller 20, which is pivotally supported by the case gripping base 2, is released at one end) The cam 22 is fixed to the center of a beam 21 that is swingably supported on a crosspiece frame, and is placed on the surface of a cam 22 that is convex upward. , so as to hang on the cam surface and support the gripping base 2 so that it will not fall when the gripping base 2 is released from the drum l.

The other end of the beam 21 is pivotally supported by the end of a piston rod 24 of an air drive mechanism 23 provided on the frame, and a compression spring 25 is installed between the end of the wand 24 and the driver 1123, so that the rod 24 is It is always biased to be in the extended position (see Figure 3).

Therefore, when air is supplied to the air drive mechanism 23 in the state shown in FIG. 3, the piston rod 24 contracts against the bias of the compression spring 25.9, and the beam 21 is moved to - as shown by the imaginary line.

As a result of swinging to this position, the upward convex cam 22 also descends, and the case gripping base 2 and the rest that are weighted on the same surface are guided by the guide 12 and fall downward. At that time, a stopper 26 fixed to a leg provided on the case gripping base 2 comes into contact with the frame of the rotating drum 1 to support the fall of the case gripping base 2,
This gives an impact to the food mold, and on the other hand, the falling inertia is applied to the baked bread remaining in the food mold, giving rise to an opportunity for the bread to be pulled out of the mold.

Next, as soon as the air supply to the air drive mechanism 23 is stopped, the compression spring 25 acts on the piston loft 24 to swing the beam 21 back to its old position, so that the food mold removes the baked bread remaining in the mold. It returns to the upper position as if leaving it behind, giving the bread another chance to come out of the mold. At that time, if you want to adjust the strength of the impact on the food mold based on conditions such as the shape of the food mold or the difference in the capacity of the baking bread, you can move the position of the leg stopper 26 provided on the case gripping base 2. Measures may be taken such as changing the falling distance of the food mold or changing the strength of the compression spring 25.

As described above, according to this embodiment, the opportunities for removing the baked bread from the food mold are: (1) when the rotary drum 1 is intermittently rotated by 180 degrees to invert or invert the food mold; and (2) when the food mold is turned upside down. When the drive mechanism 23 is activated to drop and stop the food mold, (3) the air supply to the air drive mechanism 23 is stopped and the compression spring 25
When the food mold is returned to its old position by the force of , this happens three times, and as a result, all of the normally baked bread falls out of the mold. Furthermore, if the bread remains in the mold, the mechanism for changing the magnitude of the impact mentioned above is adjusted to apply more power to the mold, but preferably the minimum impact is enough to cause the baked bread to fall out of the mold. Adding this is a means to avoid damaging the bread that falls and is housed in the bread receiving frame 4.

After all the baked breads have been removed from the inverted food mold, when the rotating drum 1 is operated for intermittent rotation of 0j80°, the roller 20, which is pivoted on the case gripping base 2, rotates with an upward convex cam surface. 22, the roller 17 comes off the cam surface 19, and the biasing force of the spring 15 acts, causing the locking plate 14 to swing around the shaft 16 and return to its old position, so that it is erected on the gripping base 2. Lock the support shaft 13 and rotate the rotating drum 1.
and the case gripping base 2 is restored. Therefore, even if the roller 20 subsequently comes off the convex cam 22,
Since the gripping base 2 is connected to the rotating drum 1, it does not move relative to the drum 1.

Regarding the subsequent operation of the above device, see [Operation] below.
Since it is as explained in the section, the explanation will be omitted.

(Part 2) In the above-mentioned device, if it is intended to simplify the engagement and disengagement mechanism between the rotating drum 1 and the case gripping base 2, the following measures may be taken. That is, the case gripping table 2 does not move in the diametrical direction with respect to the rotating drum when the food mold holding case 3 is mounted and gripped, but the roller 20 supported by the case gripping table is forced to move only when the roller 20 is pivoted on the case gripping table. Since it is only necessary to be able to move upward and downward (in the diametrical direction of the drum), in order to do this, the case gripping base 2 must be pressed and locked in the diametrical direction of the drum with a spring biased state, while at the same time it must be able to slide against the rotating drum. The holding base 2 is movably supported, and in this case, the spring bias against the gripping base 2 is (1) when pressing the base 2 toward the center of rotation of the rotating drum l, and (+1) when pressing the base 2 in the circumferential direction of the drum. There may be cases. In contrast, although not shown, the cam surface 22
The shape may be upwardly convex, downwardly concave, or provided with a positive cam. When the cam surface is upwardly convex, the operation of the air drive mechanism 23 is different from the embodiment (part 1), and must work in the extension direction; when the cam surface is downwardly concave, it is the same as in the embodiment (part 1). In the case of a positive cam, it can be used in either case, and in either case, the air drive mechanism 23 moves the roller 20 upwardly and downwardly against the elastic force of the gripper support spring. It will be forced to drive.

The magnitude and occasion of the impact force applied to the food mold and baked bread in these cases are as described in Example (Part 1).
) can be made to have no major difference.

For other operations of this example, see Example (Part 1).
Please refer to it as stated in .

(Part 3) When the case gripping base 2 is pressed and locked in the diametrical direction of the drum by a spring, and is also supported so as to be slidable in the same direction, it is not always necessary to install the air drive mechanism 23. do not.

That is, as the rotating drum rotates, a cam is installed on the circumferential surface of the drum 1 so as to press the base 2 in the diametrical direction of the drum against the biasing spring of the case holding base 2.
When the drum has completed its 180° intermittent rotation, the roller that was pivotally supported by the stand 2 and held and placed on the cam surface and pressed the stand 2 against the spring bias is moved to the cam surface. When the case grip 29 is released, the grip biasing spring, which had been pressed and compressed by the cam, expands rapidly and urges the case grip 29 to separate. The force may be applied either in the direction of the center of rotation of the rotary drum l, as in the second embodiment, or in the circumferential direction of the drum. However, in the case of this embodiment, the spring-based impact is applied to the inverted food mold or baking bread only once, but it is applied to the locking mechanism between the gripping base 2 and the rotating drum 1 and the case gripping base. The impact applying means can be greatly simplified.

For other functions of this example, see Example (Part 1)
I won't read it again because it's exactly as I explained.

(8) Effects of the Invention According to the device of the present invention, in the reversible depanner, the opportunity to take out the baked bread from the food mold is increased when the food mold is inverted or inverted, and subsequently when the food mold remains inverted. , by applying a downward impact to the Ainoho and Watari areas, adjusting the strength of the impact as necessary to ensure that all the baked bread from the mold is applied with the minimum necessary impact. At that time, the bread that falls after being removed from the mold is held horizontally and accommodated in the space of the bread receiving frame and its bottom, and is received as gently and completely as possible during baking. To provide a forced fall device for bread in a reversible depanner that does not damage the surface of bread.
