Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a method for demolding and discharging products, particularly soft foods such as bread, and delicate products, and an apparatus used therein, and in particular, a device for removing baked bread. The present invention relates to a method for demolding and discharging and a depanner device used therein.

<<Prior Art>> A device for demolding and discharging soft foods such as bread is known as a so-called depanner.

A general feature required of a method for demolding and discharging foods and a depanner device is how to discharge foods such as soft bread without losing its shape.

Conventional methods and devices related to these and 1. (A)
In order to demold the food and discharge it, a method that uses air suction to send it to a discharge conveyor after demolding,
(B) A method and an apparatus are known in which a food case (food mold) is placed on an inversion device, rotated about 180 degrees, allowed to fall naturally by gravity, placed on a discharge conveyor, and discharged.

Regarding the method and equipment for (B), when inverting a food case in a reversing device, there are two main types depending on how the product is dropped. (This is a device that flips the food case with the bottom side facing the 0-rotation axis.)

Specifically, for example, the following inversion type depanner is known.

(1) Japanese Patent Application Laid-open No. 63-55877 discloses that ``Air vent holes are formed in a part of the membrane of a self-restoring hollow container formed from a soft elastic membrane, and the diameter of the hole is limited to a desired size. A bread holder frame cushioning device for an inverted depanner characterized by having cushioning material arranged side by side 1 is disclosed, and this is an apparatus in which the cushioning material is provided on the material of the bread holder 1.

(2) JP-A-63-87931 and JP-A-63-1
No. 16635 discloses ``a reversing depanner device in which a compacted bread receiving frame is provided in the reversing device, and the bread once dropped into the receiving frame is inverted again, transferred to a zero discharge conveyor, and carried out.'' .

(3) Japanese Patent Application Laid-Open No. 6-0-3 608-7 describes an inlet conveyor that transports the baked baking sheet, and a conveyor that carries the baking sheet into a predetermined position while holding it in a direction perpendicular to the direction of conveyance. The arm member ε that rotates covers the top plate held when the arm member rotates.
In a depanner device comprising a reversing conveyor that is driven to convey the same color when rotated in the same direction, and a carry-out conveyor that is installed in parallel with the conveyor and carries out the molded sweet bread etc. from the top plate according to the drive of the reversing conveyor, a first buffer member attached to the arm member and attenuating the same force when the arm member is rotated to the carry-in conveyor side and the carry-out conveyor side, respectively; a first buffer member attached to the reversing conveyor; A reversible depanner device comprising a second buffer member that attenuates the rotational force when the reversing conveyor is rotated to the loading conveyor side and the unloading conveyor side, respectively. This is a device in which the ejection device inverts, approaches the bread, supports the bread, and depans it.

(4) Publication of Utility Model Publication No. 59-17190 states that ``several rows of air ejection holes are bored in the receiving plate of the food mold formed on the surface of the inverter main body which is rotatably supported by the rotating shaft. Air at a predetermined pressure can be supplied to the blowout hole from the air passage provided in the rotary shaft through a distributor, a hose, and an air guide pipe, and the air blowout hole in the receiving plate is provided by drilling 1 in the bottom of the food mold. Discloses a reversible depanner J that is configured to correspond to an air blowing hole for mold release, and this reversible depanner J differs from the depanner mentioned above in that it does not hold the product below the rotation axis. It is a type of depanner that can be dropped.

(5) Utility Model No. 60-98381 states that ``near the conveyor that conveys the bread cases after baking, there is a holding space for the bread cases inside and a bread escape port on the top surface; An inverter is provided which rotates forward and backward in the longitudinal direction from the inverter to the rear thereof, and has a receiving part on the upper surface close to the upper surface of the inverter, and when the inverter rotates backward, it is rotated by a power cylinder in the opposite direction. A receiving support body configured to rotate and be configured to release pressure of a power cylinder and become freely rotatable when the receiving part approaches the top surface of the reversing body from above is provided. "type device" is disclosed.

(6) JP-A No. 58-107130 discloses "a means for bringing the placement surface of a bread delivery conveyor close to a food mold that has been reversed by a depanner, and a means for moving the bread in this mold onto the said placement surface. Discloses a method for removing bread from a food mold in a depanner, which comprises a means for separating the placement of a bread delivery conveyor from the food mold and a means for transporting the bread transferred to the placement to the next process. ing.

In order to solve the above-mentioned problems, the present applicant has proposed ``Method for demolding and discharging products and apparatus used therein'' in Japanese Patent Application No. 63-296781.

<<This inventive power {Problem to be solved>>> However, among the conventional methods and devices for demolding and discharging products, the method and device (A) for sucking up the products using air suction force are as follows:
Uses a suction cup to suck up baked goods such as bread,
Because air passes through the inside of the pan, caving of the pan (
This has the problem that it tends to cause dents (which form when the temperature of the bread drops), and it tends to damage soft products such as bread. In addition, recently, the types and shapes of bread have diversified according to the tastes of consumers, and depending on the types and shapes, there have been problems that such devices using suction cups cannot cope with.

In the depanner device that uses the inverting device (B), the food case is inverted and dropped from the case to a receiving area such as a discharge conveyor. There was a problem in that products such as bread were easily deformed due to the shock caused by dropping from a distance (height), reducing the commercial value.

In addition, in (6) above, in order to solve this problem, the ejection conveyor, which is an ejection device, is raised and approached the inverted food mold, the bread is dropped, and the bread is transferred to the conveyor. After that, the ejection conveyor is lowered and released from the good mold, but with this method, the bread is in the direction of falling instantly from the inverted mold, so it is necessary to support the bread. In addition to increasing the number of elements that could cause damage, the equipment also became large-scale as it included the manufacturing process line, making it difficult to install on the current line and making it difficult to install.

This invention provides a method for demolding and discharging products that almost eliminates the falling distance of the product, has no falling speed, does not damage the product, has a compact structure, and can be relatively easily installed on an existing factory line, and the method thereof. A method for demolding and discharging products that can simplify the conventionally multiple production lines to a smaller number of lines in a factory that has processes for manufacturing a wide variety of products such as bread, and the equipment used therefor. The purpose is to provide

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention provides a method for demolding and discharging a product by holding a case containing the product by a case chuck device on a case discharging device, and then Next, place the product discharge device that discharges the product close to the case chuck device in a manner that corresponds to the height of the product, and then turn the case chuck device and product discharge device upside down in this state and stop them. , After transferring the product in the case onto the product discharge device, move the product discharge device away from the case jack device (J, discharge the product from the foot of the product discharge device, and discharge the empty case from the case discharge device J; At the same time, the next case containing a product is sent to the case chuck device on the case ejecting device and held there, and this operation is repeated one after another in the same manner to demold and eject the product from the case.

In addition, the equipment used for demolding and discharging the product includes a device that holds the case, a device that discharges the product, and a device that discharges the product to the device that holds the case, depending on the height of the product.
It consists of a device for approaching and separating the case 1, a reversing device for reversing these devices, and a device for ejecting the case.

《Operation》 The method for demolding and discharging products such as bread is to transport the case containing the product from the previous process using a device such as a conveyor, and hold it by a case chuck device (case discharging device). Next, a product discharge device for discharging the product is brought close to the case chuck device holding the case containing the product using the lift 1 device. This proximity varies depending on the size and shape of the product such as bread, but the moving distance of the lift device is determined in advance by a control signal according to the height of the product type, and the product is placed on the surface of the product discharge device. They can be placed close enough to touch. Next, in this state, the case chuck device and the product dumping device are turned upside down and stopped.

Then, the product in the case moves onto the product discharge device due to its own weight. This falling distance is almost non-existent. The lift device is then operated in reverse to move the product ejection device away from the case chuck device.

When the product ejection device is separated from the case chuck device, the product ejection device is activated to eject the product, and
The case ejection device is operated to eject the empty case, and the next case containing a product is sent to the case chuck device on the case ejection device and held there.

Thereafter, this operation is repeated in the same manner one after another, and products such as bread are demolded and discharged.

The next bread case (10
In step 2), the case is pushed and discharged onto the case discharge conveyor (8).

At this time, the belt conveyor (30) of the bread discharging device (3)h is rotated on the lower side, and the bread (ioo) is discharged to the bread discharging conveyor (4).

The depanner device repeats this operation one after another to demold and discharge the unbaked bread from the bread case.

<<Effects of the Invention>> Therefore, according to the present invention, products such as bread can be demolded and discharged without damaging them, and the conveyor for discharging remains fixed, which reduces equipment failure in relation to the production line. There is an effect.

In addition, in order to remove the product from the product case, the product ejection device is moved closer to the product case, but this distance can be easily changed depending on the type of product such as bread. Previously, multiple production lines including multiple depanners and other devices for demolding and discharging were required, but this can be done with a single demolding and discharging device. moreover,
This simplifies the production line, greatly eases maintenance and repair work, and improves production efficiency.
