Description

[Detailed Description of the Invention] (a) Purpose of the Invention [Field of Industrial Application] The present invention is to automatically take out the bread from the food mold after baking it, and transport it in an upright and aligned manner. The present invention relates to a bread holder frame having a partition plate in a reversible depanner for use in a reversible depanner.

[Conventional technology]

The bread mold placed in the reversible depanner is
The depanner is rotated intermittently to turn it upside down 180 degrees, and in this state, the freshly baked bread pulled out of the mold is received and stored in a bread receiving box that is reversibly supported directly below. The gist of the device is to turn the bread 180 degrees in one operation while storing the bread, and drop and discharge the bread in an upright position onto the mounting surface of a conveyance mechanism installed at the bottom of the receiving box. The "method for removing bread from a food mold using a depanner" is disclosed in the patent specification and accompanying drawings filed as Japanese Patent Application No. 1983-204399 by the applicant (formerly known as Oshikiri Machinery Manufacturing Co., Ltd.) prior to this application. , are disclosed to the extent that those skilled in the art can easily implement them. Also,
At that time, the specific structure of the reversible depanner device that implements the above-mentioned method was also detailed in the same specification and drawings.

By the way, in the above-mentioned device, there is a process of extracting freshly baked bread from an inverted/inverted food mold, and a process of extracting the bread from an inverted/inverted food mold.
As a process that connects the process of arranging and placing the bread on the conveyance surface of the carry-out mechanism, the bread is placed upside down and stored in a bread receiving box, and then the bread is rotated 180 degrees and the upright bread is transferred to the carrying-out mechanism from the receiving box. However, if there is an element that disturbs the alignment of the received bread somewhere in between, even if the bread is pulled out of the inverted mold in an aligned manner, it will not be possible to get it out of the depanner's conveying mechanism in an orderly manner. If the product is not delivered in its proper shape, it may cause inconvenience or adversely affect the subsequent process.

In particular, mountain-shaped bread has a rounded head, and when it is inverted and removed from the mold, it is stored in a receiving box, so even if you try to hold it in that shape, it is unstable and difficult to accept.

In this regard, in the "Method for Removing Bread from a Food Mold in a Depanner" described in Japanese Patent Application Laid-Open No. 107130/1989, which was published before the patent application for the above-mentioned method was filed, when the food mold is inverted, the bread receiving surface is Invert the loaf of bread (mountain-shaped bread) to be removed from the mold and temporarily bring it close to the opening of the mold until the bottom part does not come off the rim of the opening of the mold, and place the top of the falling bread on the receiving surface. After making contact, the same side is tilted in one direction and gradually separated from the food mold, so that the bread pulled out of the mold is aligned and falls in one direction. It cannot be said that the posture of the served bread on the receiving surface is always sufficiently controlled.

In the case of the method of Patent Application No. 60-204399, although it is not explicitly stated, a bread receptacle with a volume almost the same as the shape of the unit mold is used so as not to disturb the alignment of the bread extracted from the mold. It has been proposed to provide boxes corresponding to each other so that the bread does not lose its position in the receiving box.

This method requires a bread receiving box corresponding to the food mold of unit (i), and if the volume of the receiving box is reduced, it becomes difficult to transfer the bread smoothly.

() A gap is required somewhere between the food mold and the receiving box, or between the receiving box and the transport mechanism, for transferring the bread, making it difficult to control the posture of the bread during the transfer.

() It is necessary for the bread placed on the transport mechanism to be ejected without getting caught on the edge of the bread receiving box during transport, and to do this, the distance between the transporting mechanism and the bread receiving box must be increased. It is difficult to control the posture when the bread falls.

There is a problem as mentioned above.

[Problem that the invention seeks to solve]

Therefore, the present invention aims to solve the above-mentioned problems.When transferring bread extracted from an inverted food mold, the space within the bread receiving frame is partitioned by a plurality of partition plates to receive the bread. The gap between the received bread and the frame is narrowed to maintain the posture of the received bread, including when the bread receiving frame is reversed, and the partition plate is moved outward from the inside of the receiving frame when the bread is carried out on the conveying mechanism. It is an object of the present invention to provide a bread receiving frame having a diaphragm of a reversible depanner that can be swung so as not to interfere with the transfer of aligned breads.

(b) Structure of the invention [Means for solving the problem] In order to achieve the above object, the present invention has the following constituent elements.

(1) The rotating drum that transports bread-filled molds and discharges empty molds is rotated intermittently every 180 degrees, and from the inverted and inverted food molds, freshly baked bread is placed in a bread receiving frame set opposite to the bread molds. In the bread receiving frame of the reversible depanner, which accepts bread and allows the freshly baked bread in the inverted/inverted receiving frame to fall onto a conveying mechanism and to be carried out of the drum, a pair of plural pieces of bread are placed on both sides of the receiving frame. A swing-type partition plate is pivotally supported, and the partition plate normally swings and stops so as to occupy a position that partitions the space inside the bread receiving frame, but at least the freshly baked bread received in the receiving frame is transferred to the transfer mechanism. During the time when the bread is dropped and placed on top of the drum and is being carried out of the drum, it swings from the position that divides the space inside the receiving frame toward the outside of the receiving frame, and occupies a position that does not interfere with the conveyance of the freshly baked bread. A bread holder with a distinctive partition plate.

(2) A tension spring is installed between the pair of swinging partition plates, and the partition plates are always urged to swing and stop in the direction that defines the space within the receiving frame. A bread holder having a partition plate according to item 1 above, which comprises:

(3) The pair of swingable partition plates are configured to have a swinging and stopping position controlled by cam means provided outside the rotating drum against spring bias. A bread holder with a board.

[Effect]

Figures 5a to 5e show an overview of the overall operation including the mechanism attached to the holder frame of the present invention, and although they only illustrate the operation of one side of the pair of case grips, they can be carried out in accordance with the order of the figures. Explain the operation of the device.

(a) Step of setting the bread mold holding case on the gripping stand of the rotating drum [see Figure a]. A bread-filled food mold holding case (hereinafter also referred to as a food mold or case) is attached to a gripping stand (first
When the mold is fed onto the mold (see figure 2', hereinafter also referred to as the table), the case pushes out the already empty food mold from the gripping table towards the mold reuse process (see figure e). On the spot, the case was positioned with respect to the gripping table by the click stop mechanism, and at the same time, the push-up plate was lowered and the open clamp mechanism was closed by the spring bias, and the case was set on the table. Ru.

At that time, the focal plane opening/closing and bread conveyance mechanism, which is extended and arranged at the upper part of the opening side of the food mold that is locked on the gripping table, moves the bread that has already been taken out from the food mold out of the drum by the conveyance mechanism. After completing the discharging process [see Figure e], it continues to operate and passes through a state where the opening surface of the food mold is closed, and then is driven to a position where the opening surface of the food mold is released, at which point the operation is stopped. There is.

(b) The process of inverting the mold and removing the bread [see Figure b].

When the rotating drum rotates 180° intermittently with the gripping base locked, the food mold is also turned upside down and upside down. While placing it on the convex cam surface, a separately provided mechanism releases the connection between the gripping base and the rotating drum,
To allow the platform to move freely in the diametrical direction of the drum.

By this time, the partition plate of the opening/closing and conveyance mechanism installed between the bread receiving frame and the food mold, which are installed opposite to the opening surface of the food mold, is open, so the food mold is inverted or upside down. The freshly baked bread that has been pulled out under its own weight falls and is stored upside down in the opposing bread receiving frame. At this time, a thick cushion member with appropriate elasticity is placed on the bottom plate of the receiving frame so as not to damage the top surface of the falling bread and reduce its commercial value.
(Especially the head of mountain-shaped bread contains many air bubbles and is said to be easily damaged.) By the way, freshly baked bread does not release from the mold simply by inverting the mold by 180 degrees. may exist. After the rotating drum is rotated and stopped intermittently, the upwardly convex cam surface is rapidly moved up and down via an air cylinder mechanism, etc., so that the gripping base supported by the cam surface, the food mold, etc. By applying an impact upward and downward to break the adhesive force between the freshly baked bread and the food mold that had remained in the food mold, even if the food mold is inverted, the bread that was still attached to the mold will be removed. Securely release and drop the mold and store it in the bread receiving frame. At that time, partition plates swing and enter the space inside the bread receiving frame from both sides, as shown in the upper center of the side view of the depanner shown in Figure 2, and the space is filled with each unit of freshly baked bread. The board is divided into volumes suitable for receiving, and the board maintains the receiving posture for falling freshly baked bread. These are the partition plates that stand perpendicularly to the bottom surface of the pan receiving frame in FIG. b and partition or partition between the pans and between the pans and the outside.

In addition to the above, there is also a mechanism that applies impact in the upward and downward directions to the food mold and forcibly accommodates the bread remaining in the food mold into the bread receiving frame. It is also possible for the base to be mounted diametrically from the outside against the spring bias.

(c) Opening/closing and transport mechanism operation process [see Figure c].

Once all the bread has fallen out of the food molds and is housed and lined up upside down in the bread receiving frame, the opening/closing and conveying mechanism that extends opposite the open surface of the bread receiving frame is activated, and the screen-like member is placed in the food mold. The gap between the bread receiving frame and the pan receiving frame is blocked, and the open surface of the bread receiving frame is eventually closed. Since the bread stored in the receiving frame is surrounded by the partition plate and the opening/closing mechanism, even if the rotating drum rotates 180° intermittently and the bread receiving frame is tilted, the bread stored in the receiving frame will still be will not fall out of the frame or be disorganized.

(d) Reversing process of bread holder [see figure d].

In the middle of rotating the rotating drum 180° intermittently,
By means provided separately as previously described in step b,
The locking mechanism between the gripping base and the rotating drum operates again, and then the case gripping base is separated from the upward convex cam surface. As the rotating drum rotates, the bread receiving frame is reversed 180 degrees and turned upside down (not shown), so the bread stored in the receiving frame is erected and extended facing the open surface of the frame. drop and line up on the transport surface of the release and transport mechanism. that time,
Since the falling distance and falling speed of the bread are small, and the bread falls with its bottom facing down, there is no need to provide a cushion member to the conveyance mechanism.

(e) Bread discharging process (see Figure e).

The bread that has been dropped and placed on the opening/closing and transport mechanism is transported after the partition plate of the bread receiving frame swings to open a path for the bread (see the bread receiving frame shown at the bottom center of the side view in Figure 2). By operating the mechanism, the material is transported out of the opening/closing and transporting 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 food mold from the gripping base, and as previously described in step a, a new food mold containing bread is carried onto the stand of the rotating drum, and thereby the empty food mold The mold is extruded for the reuse process, that is, the case is replaced, and then a new mold is clamped to the table.

In this way, steps a and subsequent steps are repeated again.

The functions of the apparatus of the present invention are mainly those described in steps (b) to (e) above.

〔Example〕

FIG. 1 is a schematic front view of an embodiment of a reversible depanner equipped with a receiving frame of the present invention, and FIG. 2 is a side view. In the figure, 1 is a rotating drum, 2 is close to the outer peripheral surface of the drum 1, A food mold holding case gripping stand is installed point-symmetrically with respect to the rotation center, and a case gripping stand 2' of the same shape is installed on the opposite side. Each member described below, like the case gripping bases 2 and 2', is arranged symmetrically with respect to the rotation axis of all the drums 1, so only the configuration of one will be explained, and that of the other will be described. omitted.

3 is a food mold holding case, in which multiple food molds are stacked in parallel and integrated with a band tightened around the periphery. Reference numeral 4 denotes a bread receiving frame, and a plurality of partition plates 5 pivotally supported on both sides of the bread receiving frame are installed in correspondence with the openings of the respective food molds. Reference numeral 6 denotes a focal plane type opening/closing and pan conveying mechanism consisting of a chain and a belt, which is constructed in an "angular" shape as a whole by a plurality of pulleys and sprockets 7, and one of the chains and belts. One part is shaped like a blind, and the other part is open.
The long side of the letter extends to a position closer to the receiving frame between the opening side of the food mold and the bread receiving frame 4 installed opposite thereto, and blocks the gap between the two, but it is difficult to open/close and drive the bread conveying mechanism 6. Depending on the situation, the opening part of the belt may move between the food mold and the bread receiving frame, allowing communication between the two, allowing the bread to slip out of the inverted/inverted food mold.
This does not prevent it from falling into the bread receiving frame 4 directly below [see Figure 5b]. In addition, the freshly baked bread that falls upright on the screen belt and is lined up there is transferred by driving the opening/closing and bread conveying mechanism, and then transferred to the rotating drum via 8 groups of discharging rollers provided subsequently. 1. Take it outside [see Figure 5 d and e].

Note that the rotating drum 1 rotates intermittently every 180° around its central axis in the direction of the arrow.

9 is a carry-in conveyor for the food mold holding case 3 installed on the machine frame side, the end of which is near the circumferential surface of the drum 1;
It is installed corresponding to the stop position of the case gripping base 2'. 10 is a group of freshly baked bread transport rollers on the machine frame side facing the discharge roller group 8, and 11 is a group of rollers for transporting the empty mold case 3. The operation of the above-mentioned reversible depanner is as described in detail in the section of "Function" above, and the receiving frame of the present invention is attached to both sides above the rotation axis of the reversible depanner, and is attached to the upper and lower sides of the inverted/inverted food mold. By applying an impact in the direction, the freshly baked bread that had remained in the food mold is forcibly pulled out of the mold, and is caused to fall and be accommodated in the bread receiving frame provided oppositely (Fig. 5b). See process or Figure 1].

Figure 3 is a front view of one embodiment of the receiving frame of the present invention;
The figure is a partial side view, and each of the constituent members described below is installed symmetrically with respect to the rotation center axis of the rotary drum, so only one of them will be described. In the figure, reference numeral 4 denotes a bread receiving frame, which faces the food mold holding case gripping base and is fixed to the rotation center axis side of the rotating drum (a gripping base 4' is also provided on the opposite side). intermittently as the rotation of
Rotates every 180°. Reference numeral 12 denotes a pair of swing shafts supported parallel to each other on both sides of the bread receiving frame 4, and on the same axis are a plurality of blade plates fixed respectively at positions corresponding to the pitches of the opening edge of the food mold. A partition plate 5 is provided, and each edge of the partition plate 5 is tapered (see Fig. 3) to widen the receiving width on the bread loading side and to smoothly receive falling bread into the receiving frame. At the same time, [see FIG. 5b], the posture of the bread that has been inverted or fallen is effectively maintained within the frame by sandwiching the width of the receiving portion.

In addition, since each partition plate 5 is fixed to the swing shaft 12 with screws, it can be moved and adjusted in the direction of the shaft 12 by loosening the setscrew, thereby supporting each type of food mold depanner. Available for use.

As shown in FIG. 4, a tension spring 13 is installed between one pair of the partition plates 5 and connected to each other.
Therefore, the partition plates 5 are always urged to swing and stop all at once in the direction within the space of the bread receiving frame 4, and divide the space into sections with a capacity sufficient to receive approximately one unit of bread [Fig. 3, 5b], an arm 14 is fixed to one end of the shaft 12, and a roller 15 pivotally supported at the tip is brought into contact with a plate cam 16 provided on the machine frame outside the drum along the side of the rotating drum. This causes the partition plate 5 to swing outward from the inner space of the receiving frame 4 in response to the intermittent rotation of the rotating drum against the bias of the tension spring 13 installed on the partition plate 5. (See Figure 4).

(i) When the new food mold holding case 3 is being carried onto the case holding table 2, that is, when it is opposite to this,
The bread is erected from the installed bread receiving frame 4 and falls and is aligned on the opening/closing and transporting mechanism 6.
When the bread is being driven out of the rotating drum (see Figure 5e), the partition plate 5 is swung outward from the space of the bread receiving frame 4 so as not to obstruct the movement of the bread. It is moving and stopping [see Figures 2 and 4, bottom center]. This is done by the end of the arm 14 provided at the shaft end of the swing shaft 12 engaging and abutting the cam plate 16, and rotating the swing shaft 12 against the torque of the spring 13. .

() By the time the rotating drum intermittently rotates 180° and stops (see Figure 5b), the arm 14 comes out of contact with the cam plate 16 surface, so the spring stretched between the partition plates 5 13, all the partition plates 5 swing and stop in the direction of the space inside the bread receiving frame 4, dividing the space into sections with a volume sufficient to receive approximately one unit of bread, and separating the space from the inverted food mold. Make preparations to receive the missing bread [Second
See Figures and Figure 4, top center].

() After all the bread is taken out from the inverted food mold and placed in the bread receiving frame 4, until the rotating drum intermittently rotates 180 degrees and stops [No.
(See Figures c and d), the partition plate 5 divides the space within the space of the receiving frame 4 and holds the received bread, so that even when the bread receiving frame 4 is reversed, there is a risk of disturbing the alignment of the stored bread. do not have. However, at this time, the opening/closing and conveying mechanism is driven to close the open surface of the bread receiving frame 4.

Next, when the opening/closing and transporting mechanism 6 is driven and begins to transport the bread that has fallen and been aligned from the bread receiving frame 4 onto the mechanism mounting surface to the outside of the rotating drum [fifth
By the time [see Figure e], the partition plate 5 has swung outward from the space within the receiving frame 4 (see the bottom center of Figure 4).
Does not interfere with bread transfer.

In short, the partition plate 5 only needs to be removed from the space within the bread receiving frame when the opening/closing and transporting mechanism 6 is driven and the bread aligned on the placement surface is carried out of the drum.

From this, it can be seen that it is sufficient to install the cam plate 16 for swinging the partition plate 5 out of the receiving frame against the biasing force of the spring so as to correspond to the final part of one rotation cycle of the rotating drum.

(c) Effects of the Invention As described above, according to the present invention, (1) When receiving bread pulled out from an inverted food mold, the space inside the bread receiving frame is divided by a partition plate to prevent the bread from falling down and falling. Hold the pan in the receiving position. The present invention is the first to implement the technical concept of dividing the space within the bread receiving frame to receive bread, and releasing the division of the space within the receiving frame during bread ejection and transportation.

(2) While the bread is stored in the bread holder frame, the bread is held by dividing it with a partition plate, and the bread holder frame is held at 180°.
To ensure that the alignment of bread is not disturbed within a receiving frame even when it is turned over.

(3) After the bread stored in the bread receiving frame is erected and opened/closed, and falls and is aligned on the bread placement surface of the transport mechanism, the partition plate swings outward from the space inside the receiving frame, and the bread is Do not obstruct removal.

(4) Therefore, it is possible to sufficiently reduce the distance between the open edge of the receiving frame and the transport mechanism.
When the bread holder is turned over while still containing bread,
The partition plate and the transport mechanism surface work together to ensure the alignment of the bread, and also reduce the falling distance when the bread falls from the bread receiving frame onto the transport mechanism mounting surface, making it possible to arrange the fallen breads in an orderly manner. Make it.

(5) If the mounting interval of the partition plate to the swing shaft is adjustable, it can be used as a depanner for different types of food mold holding cases.

This results in exceptional functions and effects that cannot be expected from conventional devices.
