Description

[Detailed Description of the Invention] (a) Purpose of the Invention [Field of Industrial Application] The present invention automatically takes out the bread from the mold after baking it, stands it upright, aligns it, and carries it out. The present invention relates to a shutter of a bread receiving frame in a reversible depanner and a bread delivery device.

[Conventional technology]

The bread mold placed in the reversible depanter is
The depanner is rotated intermittently to invert every 180 degrees and inverted, and in this state, the bread taken out from the mold is received and stored in a bread receiving box that is reversibly supported directly below it, and then the receiving box is placed in a pan. A depanner is used to remove bread from a food mold by turning the bread 180 degrees in one operation while storing the bread, and ejecting the bread in an upright position onto the product placement surface of the delivery means provided below. For example, the present applicant (former company name, Oshikiri Kikai Seisakusho Co., Ltd.) filed a patent application in 1983 with regard to the "retrieval method" prior to this application.
The patent specification filed as No. 204399 and the accompanying drawings disclose the invention to the extent that one skilled in the art can easily carry out the invention. In addition, the specific configuration of the reversible depanner for implementing the above method is also described in the above specification,
It is detailed in the drawing.

By the way, in the above-mentioned depanner, the freshly baked bread is stored in the bread receiving box from the inverted/inverted food mold, and the freshly baked bread is turned 180 degrees in one operation to stand upright, and then transferred to the conveyor. When the freshly baked bread is dropped in an upright position and transferred to the outside of the depanner by driving the carry-out conveyor, there is a possibility that the freshly baked bread may unexpectedly come off from the container. (2) Remove the freshly baked bread from the mold while inverted, store it in the bread tray, and then turn the bread upright. until the receiving box is rotated 180° intermittently to transport the container.

In the case of (), there is a residual adhesive force between the food mold and the freshly baked bread, and the direction in which the centrifugal force generated by the rotation of the rotor acts presses the freshly baked bread against the food mold. There is almost no possibility that the bread will separate from the mold due to circumstances such as orientation. In the case of (), (a) the freshly baked bread is simply stored in the receiving box, and there is no adhesive force between the two.

(b) The centrifugal force applied to the bread due to the intermittent rotation of the bread receiver acts in the direction of moving the bread out of the receiver.

For this reason, in conventional devices, a presser claw for holding the bread in place is provided to prevent the freshly baked bread from falling out of the receiving box, and the presser claw is released only when the opening of the receiving box is facing upward or downward. without interfering with the movement of bread to
At other angular positions, it is necessary to control the presser claw to close so that the bread stored in the receiving box does not come off, making the mechanism complicated. However,
If it is a system that improves only the bread receiving box, a cylindrical wall that is approximately equal to the rotation radius of the rotating receiving box is provided along the outer periphery of the rotating receiving box, and windows are bored in the upper and lower walls of the peripheral wall to prevent baking. The above objective may also be achieved by forming a vertical transfer path. In any case, unless there is a wide gap between the opening of the bread receiving box and the product placement surface of the carry-out conveyor, there is a risk that freshly baked bread that has fallen from the receiving box may get stuck on the side frame when being carried out. Therefore, bread may not be transferred smoothly between the two parties.

[Problems to be solved by the invention]

Therefore, the present invention utilizes a conveyor device for carrying out freshly baked bread from a reversible depanner.
When necessary, the open side of the bread receiving frame is closed to prevent the housed bread from leaving the receiving frame when the receiving frame is rotated in order to transport the freshly baked bread that has been received upside down upright and carried out. We have developed a shutter and a bread delivery device that closes the open side of the bread receiving frame while freshly baked bread is stored inside the bread receiving frame, and by making it serve both as a means for discharging bread and as a means for opening and closing the open side of the receiving frame. The object of the present invention is to provide a device which is compact, allows the device to be installed using a small gap in a rotor, and allows smooth transfer of freshly baked bread so as not to damage the products being handled.

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

1. A rack or extension installed near the open side of the bread holder frame so as to block the gap between the bread holder frame provided on the rotation center axis side of the rotor and the food mold opening clamped on the rotor circumferential side, and close to the open side of the bread holder frame. The conveyor is driven in conjunction with the intermittent reversal movement of the rotor every 180 degrees, and the main part of the tension conveyor is positioned above the open side of the bread receiving frame. Until the freshly baked bread in the food mold has finished falling into the receiving frame, the window structure of the conveyor is positioned between the food mold and the receiving frame, so that the movement of the bread is not obstructed, and the space in the bread receiving frame is filled with freshly baked bread. After being filled, the bread placement member of the conveyor moves to stop at a position that closes the open side of the pan, while the main part of the tension conveyor occupies the lower part of the open side of the pan and is accommodated within the pan. After the freshly baked bread falls onto the bread placement member of the conveyor, the conveyor is driven to transport the bread out of the rotor, and the window structure is positioned again between the receiving frame and the food mold and stops. A reversible depanner bread delivery device, characterized in that it is controlled to move until it is moved.

[Effect]

Figures 5a to 5e show an overview of the overall operation including the attachment mechanism of the device of the present invention, and these figures represent the operation of only one of the pair of case grips provided on the rotor. . The operation of the device is explained according to the order of the figures. (a) Step of setting the bread-filled food mold holding case on the gripping stand of the rotor [see Figure 5a] ) is loaded onto the gripper provided on the rotor, the same food mold pushes out the empty food mold from the gripper toward the reuse process (see step (e)), and
A new food mold is fixed on the spot to the gripping table by the click stop mechanism and the clamping means.

At that time, a shutter and a bread delivery conveyor were installed along the open side of the bread receiving frame (not shown) provided on the rotor rotation shaft side, facing the upper part of the opening side of the food mold fixed to the gripping table. As a result, the freshly baked bread, which has already been extracted from the food mold and stored in the bread receiving frame, falls and aligns upright on the top surface of the carry-out conveyor product placement member (indicated by the thick broken line), and then moves onto the conveyor. After completing the step of discharging the food mold out of the apparatus by moving it [see step (e)], the unloading conveyor is further operated, and the article placement member closes the opening surface of the food mold, and then moves to a position where the opening surface is released. It moves to a point where it stops working.

(b) The process of reversing the food mold and taking out the freshly baked bread [see Figure 5 b] The rotor holds the food mold in place and rotates it 180° to the gap.
When the food mold is rotated, the food mold is also turned upside down and the freshly baked bread that was housed therein is pulled out by its own weight and dropped upside down into the bread receiving frame set opposite to it. At that time, a partition plate swings and intrudes into the bread receiving frame space to form the required partitioned space, and a cushion material with appropriate elasticity is layered on the bottom plate, so that the top of the bread that falls out of the mold is It is configured to receive the part softly. In preparation for the possibility that there may be some freshly baked bread that does not release from the mold simply by inverting or inverting the food mold, after the rotor rotates 180 degrees intermittently and stops, the food mold is given shock upwards and downwards to remove the remaining bread. Forcibly transfer freshly baked bread from inside the inverted food mold to the receiving frame side.

(c) Shutter and pan unloading mechanism operation process (5th
See Figure c] All the freshly baked bread fell out of the inverted food mold.
Once the bread is stored and arranged upside down in the bread receiving frame, the shutter and bread delivery mechanism that are extended and stretched along the open side of the bread receiving frame are activated, and the article placement member (indicated by the thick broken line) is placed on the open side of the bread receiving frame. It moves and stops in opposition to the bread receiving frame, and eventually closes the open surface of the bread receiving frame (shuttering action) to prevent the housed freshly baked bread from leaving the receiving frame or disrupting its alignment even when the receiving frame is tilted. .

(d) Reversing process of the bread holder frame [see Figure 5 d] When the rotor is rotated again intermittently by 180 degrees, the bread holder frame (not shown) is reversed and inverted, and the The housed freshly baked bread is dropped and aligned in an upright state through the open surface onto the shutter and the article placement member of the bread delivery mechanism. In this case, the falling distance and speed of the bread are small, and the freshly baked bread falls with its bottom facing down, so there is no need to apply cushioning material to the article placement member of the conveyance mechanism.

(e) Freshly baked bread discharge process [see Figure 5e]
The placed bread is placed on the partition plate of the receiving frame (not shown).
After the material is swung and displaced to open the passage, the conveyor is driven and the material is moved outward from the receiving frame and discharged from the rotor to the next process. The conveyor is driven even after transferring the freshly baked bread to the outside of the depanner, and closes the opening of the empty eating mold, eventually forming a window that does not partition the open side of the bread receiving frame and the opening of the eating mold. The article mounting member is driven to a position where it stops between the two sections, that is, a position where the article placement member is removed from the section, and then stops there.

At the same time, the fixation of the empty mold is released, and a new mold containing freshly baked bread is carried into the rotor's gripping stand as described in step (a), thereby pushing the empty mold toward the reuse process. Let it come out.

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

The functions of the apparatus of the present invention are those described above in steps (a), (c), and (e).

〔Example〕

Fig. 1 is a schematic front view of an embodiment of a reversible depanner equipped with the device of the present invention, and Fig. 2 is a side view thereof. , a point (line) relative to its rotation center axis
The food mold holding case grips are installed symmetrically, and a case grip 2' of the same shape is installed on the opposite side.

Each member explained below is the case gripping base 2, 2'.
Similarly, all points (lines) are relative to the rotational axis of the rotor.
Although they are arranged symmetrically, for convenience, only the configuration of one side will be explained, and the description of the other side will be omitted.
3 is a food mold holding case in which a plurality of food molds are stacked in parallel and integrated and tightened with a band; 4 is a bread receiving frame; A plurality of pairs of partition plates 5 which are pivotably supported on both sides are installed. The partition plate 5 is formed to divide the space inside the bread receiving frame into units of capacity suitable for accommodating each unit of freshly baked bread, and to be able to swing into the space outside the receiving frame (see Fig. 2). There is.
Reference numeral 6 denotes a shutter and bread conveyance mechanism consisting of an endless chain and an article placement member, which is constructed in an overall shape of a square by a plurality of sprockets 7. It extends along the side of the receiving frame between the opening side and the open side of the bread receiving frame 4 installed opposite to the opening side, and blocks the gap between the two, depending on how the transport mechanism 6 is driven. In some cases, the position of the article placement member may be different from the food mold and the receiving frame 4.
The bread tray is moved to a space other than the space between the bread pan and the bread pan to create communication between the two, so as not to prevent the freshly baked bread from slipping out of the inverted/inverted food mold and falling onto the bread receiving frame 4 directly below it [Fig. 5 b reference〕. Also, depending on the driving condition, the article placement member of the transport mechanism may stop at a position opposite to the open side of the bread receiving frame and close the open side of the receiving frame (shutter action), allowing the bread receiving frame 4 to be accommodated even if it is reversed or tilted. While there is no risk of the freshly baked bread falling out of the receiving frame or disturbing the alignment, the surface of the placing member prevents the freshly baked bread in the inverted bread receiving frame from falling in an upright position. Then, the conveyor is driven, and the conveyor is conveyed out of the rotor 1 via the discharging roller group 8 provided in succession (see FIGS. 5d and 5e).

Note that the rotor 1 rotates intermittently every 180 degrees in the direction of the arrow around its rotation axis.

9 is a conveyor for charging the food mold holding case 3 provided on the machine frame side, the end of which is near the circumferential surface of the rotor 1;
It is installed corresponding to the stop position of the case gripping stand 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 reversible depanner is as described above.
As described in detail in the section above, the device of the present invention has the functions of opening and closing the open side of the bread holder frame when storing freshly baked bread, and carrying out the freshly baked bread that has fallen onto the placement member out of the rotor. [See Figures 5a to 5e].

Fig. 3 is an enlarged front view of the waist of one embodiment of the shutter and bread delivery device of the present invention, and Fig. 4 is a perspective view thereof. , and the one provided on the opposite side. Unless otherwise specified, the same structure is provided in point (line) symmetry with respect to the axis, and is the same as in the case of the explanation of Fig. 1. be.

In the figure, 6 consists of two endless chains provided in parallel, and is supported by a plurality of sprockets 7, _7-2 ... _7-6 , which are pivotally supported on the rotor 1 in parallel to the rotation axis 12 of the rotor 1. , when viewed from the front, it is stretched in a ``shi'' shape. A blind-shaped article mounting member 13 is installed in a part between the two endless chains 6, 6, and the width of the chain in the longitudinal direction is the total length of the endless chain in this embodiment. By driving the same chain, the placing member 13 acts as a shutter on the open side of the bread receiving frame 4, supports the baked bread that has fallen from the receiving frame 4, and conveys it to the discharge roller group 8 side. That is, the pan conveyance mechanism 6 is entirely driven and controlled by a sprocket _7-3 that is pivotally supported in close proximity to the rotor rotating shaft 12, but the sprocket _7-3 is further connected to the rotor through a drive shaft and a sprocket 14. It is connected to be driven by a chain installed on a sprocket 15 which is supported concentrically with the shaft 12. Sprocket 1
sprocket 1 connected to sprocket 5 and provided concentrically with this
6 has a chain connected to the motor via the clutch mechanism 17, so the clutch mechanism 1
By opening and closing 7, power is transmitted from sprocket 16 to sprocket 15 to sprocket 14 to sprocket _7-3 , and the movement of endless chain conveyor (shutter and bread conveyance mechanism) 6 can be controlled. Since the sprockets 15 and 16 are supported coaxially with the rotor shaft 12, the position of the chain conveyor 6 can be controlled independently of the intermittent rotational movement of the rotor 1.

Incidentally, as shown in FIG.
This is accomplished by installing a power transmission mechanism interlocked with the motor via the clutch mechanism 19, and synchronizing the clutch mechanism 19 and the 180° intermittent rotation of the rotor 1. Then, while the rotor 1 is rotating,
If the clutch mechanism 17 is left open, power will not be transmitted to the chain conveyor 6 during that time, so the conveyor 6 will not move from its old position while the rotor 1 is rotating.

Now, if the clutch 19 is released and the rotor 1 is stopped at the phase shown in the third figure, the bread receiving frame 4 will be reversed so that its open part will face downward, and the freshly baked bread housed in the receiving frame 4 will be directed downward. However, at that time, since the shutter and the article placement part 13 of the conveyance mechanism 6 are stopped at positions opposite to the open part of the bread receiving frame, the freshly baked bread is erected and placed on the surface of the placement member 13 of the conveyance mechanism 6. Align on top (see Figure 5d).

At the same time, the receiving frame partition plate 5 swings and retreats from the moving direction of the bread, so after its operation, the clutch mechanism 17 closes, driving the conveying mechanism 6 in the direction of the arrow, and placing the bread on the article placing member 13. The freshly baked bread is conveyed in the direction of the discharge roller group 8. The clutch mechanism 17 is a mounting member 13 attached to the transport mechanism.
After delivering the bread placed on it to the discharge roller group 8, it moves around the end side sprocket _7-6 and moves in the return direction on the side facing the case gripping base 2, and is placed on the sprocket 7, at least The chain conveyor is driven so as to move to a position where there is no interruption between the bread receiving frame opening part and the opening surface of the food mold clamped to the case gripping base 2 and then stopped, and then the chain conveyor is opened (see FIG. 5a).

On the other hand, the article mounting member attached to the shutter and the transport mechanism 6', which are installed point (line) symmetrically with the shutter and the transport mechanism 6 with respect to the rotor rotation axis 12, is simultaneously loaded from the sprocket 15. The transmitted power is transmitted to the mechanism 6' so that the mounting member moves to a position where it faces the upward opening of the other pan holder and closes it all, and then stops.
Drives the chain conveyor that makes up the

That is, the conveying mechanisms 6, 6' sandwiching the rotor rotating shaft 12 are controlled by opening and closing the clutch mechanism 17 so that they move and stop at fixed positions symmetrically with each other in synchronization with the intermittent rotation of the rotor.

As mentioned above, by the time the article placement member of the conveyance mechanism 6' covers the other bread receiving frame opening and closing it, all the freshly baked bread from the ready-to-eat mold clamped opposite to it has been transferred to the receiving frame. Needless to say, it fell and was stored on the side. As a result, the article placing member of the mechanism 6' acts as a shutter for the open part of the bread receiving frame, and in the subsequent process, the rotor 1 is
It is driven 180 degrees intermittently, and as a result, the receiving frame that houses the freshly baked bread tilts, and even if the open part is positioned downward, the housed bread will not roll outward and cause damage. , when the bread holder has stopped at the position 4 shown in the third diagram,
Freshly baked bread falls onto the product placement member while standing upright.
Arrange them and prepare to take them out of the depanner [see Figure 5 d]. The next step returns to the beginning of the description of this embodiment, and one cycle of the depanner is completed.

The explanation of other functions and effects related to this example overlaps with the description in the previous [Operation] section, so
Omit this.

(C) Effects of the Invention As described above, according to the present invention, the space occupied by the bread receiving frame is reduced by combining the functions of the bread carrying means and the shutter mechanism of the opening part of the bread receiving frame into one device. By simplifying the mechanism so that it can be installed even in the narrow gap between the food mold holding stand provided on the rotor and the bread receiving frame, and by adding mechanisms such as a chain and sprocket,
It makes it easier to control the stop position of the shutter part, and
It has special functions that cannot be expected from conventional devices, such as eliminating the need to transfer the baked bread onto the conveyor table when discharging the bread from the rotor, and preventing the product (bread) from being damaged by the depanner.・It is effective.
