Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a method for discharging a product in a depanner device, and a depanner device used therein, specifically bread in the depanner device, and more specifically bread bread having a curved head. and a depanner device used therein.

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

A conventional depanner device is a device that demolds bread, etc. that has been baked in a mold from a bread case (mold). The methods of demolding and ejecting bread, etc. using this device are as follows: a. Bread, etc. is removed using air suction power. Devices and methods are known that use an inverting device to invert a mold containing bread, etc., and drop the baked bread from the top onto a discharge conveyor.

However, devices and methods that use air suction force have the problem of easily creating caving in the bread (dents that form when the temperature of the bread drops), and devices and methods that remove the mold by inverting the mold due to inversion. A height is required between the receiving part (discharge conveyor, etc.),
There was a problem in that products such as bread were easily deformed by a shock caused by a fall.

In order to solve these problems, the present applicant has proposed Japanese Patent Application No. 63-296781 and Japanese Patent Application No. 1-
No. 163090 proposes a method for demolding and discharging products and equipment used therefor.

In addition, recently, bread, especially box-shaped bread, has become more common, with a chevron-shaped cross section and a semi-cylindrical upper surface, rather than the traditional flat, rectangular cross-section. There are many phenomena that are difficult to line up neatly.

JP-A-58-107130 is known as a method for taking out bread from a bread case of a depanner device.

<<Problems to be Solved by the Invention>> When bread, especially box-shaped bread, has a chevron-shaped top surface that swells into a semi-cylindrical shape, it is difficult to pass the bread from the top surface of the semi-cylindrical shape onto the discharge conveyor. After the bread is placed or dropped, the discharging conveyor starts moving in the discharging direction (forward rotation), so there is a problem that the bread falls in different directions regardless of the direction in which the discharging conveyor moves. (Figures 9 to 11
(see figure).

As a result, products such as bread are easily damaged during packaging and transport, and are also prone to damage when transporting the products.It also takes time to transport the products, which is inconvenient and reduces manufacturing efficiency. I came across a problem.

In addition, Japanese Patent Application Laid-open No. 107130/1983 is known as a method for aligning the bread that has been taken out. In this method, a horizontal discharge conveyor is used to arrange the bread, etc. from the bread case, and then the discharge conveyor itself is moved. Since the method involves tilting bread etc. in a certain direction by tilting it up and down, the device becomes large and complicated, and there are problems such as the installation location and the difficulty of holding the machine.

Furthermore, with this device, the bread and the like fall when the discharge conveyor is horizontal, so if the top surface is curved, the direction in which the bread falls is unstable, which is the same problem as in the past.

This invention provides a method for discharging products such as bread, in which the bread is placed upside down in an orderly and stable manner on a discharging conveyor, even if the bread has a semi-cylindrical curved top surface, and its use therein. The purpose is to obtain a device that

<<Means for Solving the Problem>> In order to achieve this object, the present invention holds a case containing a product by a case chuck device, then brings the case chuck device close to a product discharge conveyor in a manner corresponding to the height of the product, and then In this state, the case chuck device and product discharge conveyor are turned upside down using a reversing device and stopped, and after the products in the case are transferred onto the product discharge conveyor, the case chuck device is moved away from the product discharge conveyor. In the product discharging method of a depanner device that discharges products by a product discharging conveyor; a stop for receiving the product coming off from the case, and a product discharging conveyor for discharging the product, when the product is placed on the surface of the product discharging conveyor and the product is detached from the case. , the running direction of the product discharging conveyor should be run in the opposite direction to the product discharging direction for a short period of time, and then immediately run in the forward direction again in the product discharging direction, or the product may be placed on the product discharging conveyor and the product may be removed from the case for a short period of time. A method for discharging products from a depanner device is proposed, in which the product discharging conveyor is made to run faster than the normal speed for a time, and then immediately runs again at the normal discharge speed.

Furthermore, in order to ensure that the product is placed upside down, the case containing the product is held by a case chuck device.
Next, the case chuck device is brought close to the product discharge conveyor in a manner that corresponds to the height of the product, and then, in this state, the case chuck device and the product discharge conveyor are turned upside down using a reversing device and stopped. In the product discharging method of the depanner device, in which after the product inside is transferred onto the product discharging conveyor, the case chuck device is moved away from the product discharging conveyor and the product is discharged by the product discharging conveyor; The product discharge conveyor is configured to be tilted low towards the product discharge direction, and when the product is placed on the surface of the product discharge conveyor and is removed from the case, the running direction of the product discharge conveyor is rotated in the opposite direction to the product discharge direction for a short time. We propose a method for discharging a product using a depanner device, in which the depanner device is configured to allow the depanner to rotate in the normal direction again in the product discharging direction.

Alternatively, in order to ensure the upside down direction of the product, the case containing the product is held by a case chuck device, then the case chuck device is brought close to the product discharge conveyor at a height corresponding to the product, and then the case chuck device is held in that state. Then, the product discharging conveyor is turned upside down using a reversing device and stopped, and the products in the case are transferred onto the product discharging conveyor.The case chuck device is then moved away from the product discharging conveyor, and the products are transferred to the product discharging conveyor. In the product discharging method of the depanner device, the product discharging conveyor that receives and discharges the product from the case is configured to be highly inclined toward the product discharging direction, so that the product is placed on the surface of the product discharging conveyor and the product is discharged from the case. We propose a method for discharging products from a depanner device, in which the product discharging conveyor is run faster than the normal running speed for a short period of time when the depanner is leaving the product, and then immediately runs at the normal speed again. Furthermore, the devices include a case chuck device for holding cases, a product discharge conveyor for discharging products, a device for moving the case chuck device toward or away from the product discharge conveyor according to the height of the product, and a device for reversing these devices. In a depanner device having a reversing device that causes the product to be discharged; when the product is placed on the surface of the discharge conveyor and the product is removed from the case, the product discharge conveyor is caused to run in a direction opposite to the product discharge direction for a short period of time; We propose a depanner device having an automatic device that immediately rotates forward again in the product discharge direction.

It also includes a case chuck device for holding cases, a product discharge conveyor for discharging products, a device for moving the case chuck device toward and away from the product discharge conveyor according to the height of the product, and a reversing device for reversing these devices. In a depanner device having a device; the product discharge conveyor is configured to be inclined low toward the product discharge direction, and when the product is placed on the surface of the product discharge conveyor and the product is removed from the case, the product discharge conveyor is We propose a depanner device having an automatic device that causes the depanner to run in the opposite direction to the product discharge direction, and then immediately rotates forward again in the product discharge direction.

Alternatively, a case chuck device for holding cases, a product discharge conveyor for discharging products, a device for moving the case chuck device toward or away from the product discharge conveyor according to the height of the product, and a reversing device for reversing these devices. In a depanner device having a device; the product discharge conveyor of the depanner device is configured to be highly inclined toward the product discharge direction, and when the product is placed on the surface of the product discharge conveyor and the product is separated from the case, A depanner device is proposed that has an automatic device that increases the running speed of a product discharge conveyor above the normal discharge speed and then immediately runs the product discharge conveyor at the normal running speed.

≪Operation≫ When products such as bread in a depanner device are inverted, each case containing the product is turned over and begins to come out of the case, and its head rests on the surface of the discharge conveyor, but its base is supported by the case. There is. After reversing, when the case is raised and the product is removed from the case, the discharge conveyor is rotated in the opposite direction to the discharge direction for a short period of time, or is run at a speed higher than the normal speed in the discharge direction. The distance of this reverse rotation running or faster running distance varies depending on the type of product such as bread, but is approximately equal to or slightly longer than the width of the product.

By this reverse running or fast running,
The part of the product that is in contact with the discharge conveyor, that is, the head, momentarily swings in the opposite direction, and the products fall in a neatly aligned direction in the forward or reverse direction.

This falling state is more secure in a configuration in which the discharge conveyor is inclined.

After running in reverse rotation and running at a faster speed than the normal discharge speed, the discharge conveyor runs in the forward rotation direction or at the normal discharge speed to discharge and convey the products.

Reverse running of the discharge conveyor, or running faster than usual, is accomplished by providing an automatic device that inputs the reverse rotation time, etc., into the rotating device of the discharge conveyor.

In this embodiment, the case mounting section 6 is composed of a rotating roller conveyor, but it may also be composed of a belt conveyor or a plate-shaped body with a smooth surface. The case mounting section 6 is provided at approximately the same height as the chain conveyor of the case supply device 7 located on the upstream side and the roller conveyor of the case transport conveyor 8 located on the downstream side.

The chain conveyor of the case supply device 7 has two case pushing protrusions 70 that protrude from the conveyor surface.
They are installed so that they are on opposite sides.

The bread discharge conveyors 1a and 1b are located on the axis 20 of the reversing device 2, and are respectively provided above and below the axis 20 of the reversing device 2 at fixed intervals from the axis 20. Therefore, even if they are rotated 180 degrees, they will remain in the same position.

The bread discharge conveyors 1a and 1b each consist of an endless belt conveyor. The bread discharge conveyors 1a and 1b have drive rollers 11 on the supply side.
and an endless belt 12 stretched between a tail pulley 10 on the discharge side.

When the bread discharge conveyors 1a and 1b are located above the reversing device 2, the discharge side is configured to be lower than the supply side by a distance h as shown in FIGS. 2 and 3 to 5, or Alternatively, as shown in FIGS. 6 to 8, the discharge side is configured to be higher than the supply side by a distance h.

The case transport conveyor 8 consists of a roller conveyor whose starting point is the discharge end of the case mounting section 6. Of course, the case conveyor 8 may be constructed by a chain conveyor or the like.

Next, an embodiment of a method for discharging bread using this depanner device will be described with reference to FIGS. 3 to 5.

The bread case 102 is the bread case 101
and 100 pieces of bread baked in it. The bread-filled bread case 102 rides on the supply conveyor of the case supply device 7, and is attached to the chain conveyor of the case supply device 7 so as to protrude from the surface of the conveyor. The bread case 102 is pushed and moved onto the case placement section 6.

The bread case 102 with bread is placed on the case mounting section 6
When placed on the case, it is chucked (held) by the case chuck device 5a.

Next, the double-X-shaped four-section mechanism of the lift device 3 is closed and retracted, and the case chuck device 5a is raised an appropriate distance so that the tip of the bread 100 in the bread case 101 either touches or does not touch the bread discharge conveyor 1a. close enough to each other. At this time, since the bread discharge conveyor 1a is inclined so that the discharge side is lower, the head of the bread 100 and the bread discharge conveyor 1
The spacing between the a surfaces is slightly larger on the discharge side.

The upward movement distance of the case chuck device 5a is controlled by an electrical signal,
The moving distance is stored and controlled according to the height of the 00 type. In this embodiment, when the height of the product is input from an operation panel (not shown), the distance the piston rod moves is controlled by the product height switch of the lift power unit (air cylinder) 30.
In addition, the product height switch is the case supply device 7.
It is electrically linked to a product height detection device (not shown) installed at the upper entrance, and if an object that is higher than the height of the product entered in advance from the operation panel attempts to enter, an alarm will be issued and the device will shut down. Stop.

The lift device 3 consists of two vertically X-shaped four-section mechanisms, and case chuck devices 5b are provided on the upper and lower sides 180° opposite each other, so when the lower side performs this operation, the case chuck device 5b on the opposite side (upper side) is activated. decline at a similar rate. Next, the reversing device 2 is activated, and both the case chuck devices 5a, 5b and the bread discharge conveyors 1a, 1b are rotated 180° (half rotation) around the axis 20 of the reversing device 2, and the upper and lower case chuck devices 5a, 5b are rotated by 180 degrees (half rotation). Then, the bread discharge conveyors 1a and 1b are reversed. Then, the case chuck device 5a and the bread case 101 held therein are turned upside down, so that the bread 100 in the bread case 101 is turned over and its head is placed on the surface of the stationary bread discharge conveyor 1a. bordering,
It becomes a state of being transferred. At this time, the base of the bread 100 is still in the bread case 101, and the bread case 1
It is supported by 01. (Figure 3).

Next, the X-shaped four-section mechanism of the lift device 3 is opened, and the case chuck device 5a and the pan case 101 are opened.
When the base of the bread 100 is removed from the bread case 101, the bread discharge conveyor 1a is reversely rotated for a short time in the direction opposite to the discharge direction D (FIG. 4). The time when the bread 100 is separated from the bread case 101 includes a short period of time before the base of the bread 100 separates from the support of the bread case 101 and a short time after the base part of the bread 100 separates from the support of the bread case 101. Further, the travel distance of the bread discharge conveyor 1a in reverse rotation varies depending on the shape and type of the bread 100, but is about the width of the bread 100 plus alpha, that is, about 100 to 150 mm. R in the drawing
indicates the rotational direction of the bread discharge conveyors 1a, 1b at that time.

An appropriate number of breads 100 arranged in parallel on the upper surface of the bread discharging conveyor 1a swing for a moment in the opposite direction to the discharging direction D during this short run before falling over themselves. According to
The body parts on the base side fall all at once in the ejection direction D (Fig. 5). This is also due to the fact that the bread discharge conveyor 1 has a low discharge side and is inclined with a height difference of h.

After this short period of reverse rotation, the bread discharge conveyor 1a immediately begins to rotate forward in the discharge direction D, and transfers the bread 100 that has fallen neatly in the same direction to the bread transport conveyor 4.

Next, on the lower side, the next bread case 102 containing bread is sent onto the case placement section 6 and chucked by the case chuck device 5b.

Next, the X-shaped four-section mechanism of the lift device 3 is closed and retracted again, and the case chuck device 5b is raised until the tip of the bread in the lower bread case 102 touches the lower bread discharge conveyor 1b. bring them close together.

Then, turn the reversing device 2 around its axis 20 again.
The case chuck devices 5b, 5a and the bread discharge conveyors 1a, 1b are turned upside down by 180° rotation, and the bread 100 in the bread case 101 is transferred and placed on the surface side of the bread discharge conveyor 1b.

Next, the X-shaped four-section mechanism of the lift device 3 is opened, and the case chuck device 5b and the pan case 10 are opened.
1 and when the bread 100 is removed from the bread case 101, the stationary bread discharge conveyor 1b is rotated in the opposite direction as described above, and the head of the bread 100 in contact with the bread discharge conveyor 1b is moved in the discharge direction D. Shake it to the opposite side and tilt the base of the pan 100 in the discharge direction.

After this short period of reverse rotation, the bread discharge conveyor 1b immediately begins to rotate forward in the discharge direction D, and transfers the bread 100 that has fallen neatly in the same direction to the bread conveyor 4.

At this time, on the lower side, the case chuck device 5a removes the chuck of the empty bread case 101,
The empty bread case 101 becomes free on the case placement part 6, and the rotating roller conveyor of the case placement part 6 is activated to push the empty bread case 101 onto the case transport conveyor 8.

The depanner device repeats this operation sequentially,
The baked bread is removed from the bread case and discharged.

Further, to explain the method for discharging products from the depanner apparatus shown in FIGS. 6 to 8, the bread discharging conveyor 1 is configured such that the discharging side is inclined higher than the supply side by a height difference of h, so that the bread discharging conveyor 1 is The distance between the head of the bread 100 and the surface of the bread discharging conveyor 1 is almost zero on the discharging side of the bread discharging conveyor 1, but there is a gap as you go to the supply side of the bread discharging conveyor 1a (6th figure).

Next, the X-shaped four-section mechanism of the lift device 3 is expanded to raise the case chuck device 5a and the bread case 101 chucked thereto, and when the base of the bread 100 is separated from the bread case 101, the bread discharge conveyor 1 and run for a short period of time (Fig. 7). The time when the bread 100 separates from the bread case 101 includes a short time before and after the base of the bread 100 separates from the support of the bread case 101.

Further, this running distance varies depending on the shape and type of the bread 100, but is about the width of the bread 100 plus an alpha, that is, about 100 to 150 mm.

During this run, the appropriate number of breads 100 arranged in parallel on the upper surface of the bread discharge conveyor 1 momentarily swing their heads in contact with the bread discharge conveyor 1 in the high slope discharge direction D, thereby causing the bodies on the opposite side to swing. The parts fall all at once toward the supply side (Fig. 8).

After this short-term fast run, the bread discharge conveyor 1a immediately starts running at a normal speed, and the bread 100 that has fallen neatly in the same direction is directly transported in the discharge direction D.
and transfer it to the bread conveyor 4.

<<Effects of the Invention>> Therefore, according to the present invention, when a product such as bread is demolded and discharged in a depanner device, the product such as bread falls neatly in the same direction, so that the bread is not damaged when it is discharged. This has the effect of improving manufacturing efficiency.

In particular, since bread can be tipped in the same direction regardless of its type or shape, it has become possible to continuously manufacture bread of various types and shapes in accordance with consumer requests. be.
