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.

≪Problems to be solved by this invention≫ However, the conventional method of demolding and discharging the product,
Among the devices, (A) uses the suction power of air to suck up the product.The device uses a suction cup to suck out products such as baked bread, and the air passes through the inside of the bread. However, bread caving (a dent formed when the temperature of the bread drops) is likely to occur, and soft products such as bread are easily damaged. In addition, recently, depending on consumer preferences,
The types and shapes of bread have diversified, and depending on the type and shape, there have been problems that cannot be addressed by such a device using a suction cup.

In the depanner device using the reversing device (B),
The food case is inverted and dropped from the case to a receiving part such as a discharge conveyor, but there must be some distance between the case and the receiving part to allow the food case to be inverted. There was a problem that the products such as the above were easily deformed and the commercial value decreased.

In addition, in (6) above, in order to solve this problem, the discharging conveyor, which is the discharging device, is raised and approached the inverted food mold, and the bread is dropped onto the conveyor. After the bread has been transferred, the ejection conveyor is lowered from the food mold, and the bread is removed. As the number of factors that damage
Since it includes the manufacturing process line, the equipment is large-scale and difficult to install on the current line, making it difficult to install.

This invention almost eliminates the falling distance of the product, so there is no falling speed, and the product is not damaged.
A method for demolding and discharging products that has a compact structure and can be relatively easily installed on existing factory lines, and the equipment used for it. The purpose of the present invention is to provide a method for demolding and discharging a product, which can simplify the conventional manufacturing line to a smaller number of lines, and an apparatus used therefor.

<<Means for Solving the Problems>> In order to solve the above-mentioned problems, the present invention provides a method for demolding and discharging products by moving the case containing the product from the case supply device located above the axis of the reversing device. The case containing the product is held onto the loading section by a case chuck device, and then the product discharge device for discharging the product is brought close to the case chuck device from above in a manner that corresponds to the height of the product. Then, turn the case chuck device and product discharge device upside down using a reversing device and stop, drop the product in the case onto the product discharge device, and then move the product discharge device away from the case chuck device. The product is discharged from the product discharge device located below the axis of the reversing device, the product is sent out by the product delivery device, and the empty case is discharged from the case discharge device located above the axis of the reversing device. The case containing the product is fed to and held by a case chuck device on the case placement section, and this operation is repeated one after another in the same manner to demold and discharge the product from the case.

In addition, the device used for demolding and discharging the product includes a device for holding the case, a device for discharging the product, and a device for discharging the product to the device that holds the case from above, depending on the height of the product. a reversing device for reversing these devices; a case feeding device located above the axis of the reversing device; a case discharging device located above the axis of the reversing device; It consists of a device used for demolding and ejecting products, and a product delivery device located below the axis of the reversing device.

≪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,
It is held by a case chuck device on the case ejector. Next, a product discharge device for discharging the product is brought close to the case chuck device holding the product-filled case using a lift 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 each other. Next, in this state, the case chuck device and the product discharge 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 discharge device leaves the case chuck device, the product discharge device is activated to discharge the product, the case discharge device is activated to discharge the empty case, and the next case containing product is placed on the case chuck device. Feed it into the case chuck device and hold it.

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

The bread case 102 carried by the case supply device 7 is pushed by the case pushing protrusion 71 at the rear thereof, and is placed on the case mounting portion 6 of the depanner device. At this time, if there is an empty bread case 101 on the case placement part 6, it is pushed out by the bread case 102 containing bread. The bread case 102 is then chucked by the chuck actuator 54 of the case chuck device 5. The chuck actuator 54 of the case chuck device 5 is configured to operate the chuck actuator 54 of the case chuck device 5 to
Before the 02 is brought in, the piston rod of the air cylinder 53 of the chuck power section is extended,
The distance between the left and right chuck actuators 54 is widened.

When the piston rod 3 expands and contracts, it expands and contracts the same distance left and right around the pinion gear, so the chuck actuator 54 opens and closes without being deviated from the center of the depanner device. Bread case with bread 10
2 enters between the chuck actuators 54, the air cylinder 53 is contracted, and the left and right chuck actuators 54 press it inward to hold it.

When the bread case 102 is chucked from left and right by the chuck actuator 54 of the case chuck device 5, the piston rod 201 of the air cylinder 20 of the lift device 2 is extended, and the horizontal movement bar 21 is moved toward the discharge end side. The bread discharging devices 3a and 3b connected to the arm bar 25 are brought closer to the axis 10 by moving the bread discharging devices 3a and 3b connected to the arm bar 25 by appropriately widening the distance between the fulcrum shafts 24 and reducing the height of the X-shaped four-bar mechanism. Therefore, the upper bread ejecting device 3a comes very close to the top surface of the bread 100 so as to come into contact with it. The moving distance of the piston rod 201 of the air cylinder 20 can be changed depending on the type and shape of the baked bread, that is, its height. Adjust the proximity distance to the surface of the discharge device 3a. In this embodiment, the stroke of the air cylinder 20 is changed. The stroke of the air cylinder 20 depends on the position of a product height switch 204 provided on the outer circumferential side of the cylinder body. When the bread height is input from the operation panel (not shown), the product height switch 204 connects electrically with the product height detection device (not shown) provided at the entrance on the case supply device 7. If the height of the pan 100 that is about to enter the depanner device is too high, the air cylinder 2
Stop the movement of 0. For example, if you set the pan height to 125mm using the control panel (not shown),
The product height switch 204 is set in advance at 125 on the cylinder body side of the air cylinder 20.
It is placed at a position corresponding to mm. In addition, a product height detection device (not shown) issues an alarm and stops the device if bread of 125 mm or more tries to enter.
When the piston head (not shown) of the air cylinder 20 advances to the position of the product height switch 204, the switch is activated, the air circuit is activated electrically, and the brake section of the air cylinder 20 is activated, causing the piston rod 201 to move. Fix it. At this time,
The bread discharging device 3 stops at a position matching the height of products such as bread. Next, the reversing power unit 12 of the reversing device 1 is activated to rotate the shaft center 10 by half a rotation of 180 degrees. By turning the bread discharging devices 3a, 3b and the case chuck devices 5a, 5b upside down and reversing the front and back, the bread 100 in the bread case 101 falls onto the lower surface of the bread discharging device 3a.

Next, the piston rod 201 of the air cylinder 20 of the lift device 2 is shortened, the horizontal movement bar 21 is moved to the supply end side, the distance between it and the fulcrum shaft 24 is appropriately narrowed, and the X-shaped four-bar mechanism is extended high. ,
Bread ejection device 3 connected to arm bar 25
a and 3b are separated from the axis 10.

Next, the air cylinder 53 of only the case chuck device 5 on the case discharge conveyor 8 side (upper side) of the case chuck devices 5a, 5b is extended, the left and right chuck actuators 54 are separated, and the bread cases 101 are separated.

Then, when a new bread case 102 containing bread from the case supply device 7 is pushed by the case pushing protrusion 71 of the chain conveyor 70 and carried onto the case mounting section 6, the next bread case 102 containing bread will be pushed. The case is then discharged onto the case discharge conveyor 8.

At this time, the belt conveyor 30 of the bread discharging device 3b is rotated on the lower side, and the bread 100 is discharged to the bread discharging conveyor 4.

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

≪Effects of the Invention≫ Therefore, according to the present invention, products such as bread can be demolded and discharged without damaging them, and since the conveyor for discharging remains fixed, there are fewer failures of the equipment in relation to the production line. It has the effect of becoming.

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. Although a plurality of production lines including a plurality of devices such as a plurality of depanners for demolding and discharging the mold are required, this can be done with one mold demolding and discharging device. Furthermore, this simplifies the production line, greatly simplifies maintenance and repair work, and improves production efficiency.
