Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a non-stop packaging device and a method thereof. To enable smooth conveyance without causing any problems and without stopping the driving of a packing machine and a belt conveyor even during banding, and to speed up work.

[Conventional technology]

Conventionally, when automatically banding stacked products, first, the packaging machine itself is provided with a heald or roller drive mechanism, and the products are stopped at a binding position and bound.

In order to increase the banding processing capacity, a speed amplifier for the packaging machine conveyor belt is required. Once speed amplifiers are realized, the packaging equipment will have to stop suddenly when stopping the belt rotation.
Product collapses.

Therefore, in order to prevent the load from collapsing, a stopper device is installed at the tip of the packing machine, and if side alignment is required,
A side aligning device is provided, and a back beating device is provided to pick up the stacked products from the front, back, right and left, and then banding is performed.

That is, when banding items to be packaged, the process is as follows: stopping the conveying device, arranging the products, bundling, and discharging, and the conveying device is repeatedly stopped and started each time.

[Problem to be solved by the invention]

However, when banding with the above-mentioned packaging machine, if the speed of the conveyor heddle is increased to increase the banding processing capacity, the packaging machine will suddenly stop when the belt conveyor stops rotating. Occasionally, the load may collapse.

The above-mentioned packaging machine has a stopper installed on the tip side in the running direction to prevent the load from collapsing, and the load is placed against this for banding, but if the product is a random size with uneven length, the stopper The disadvantage was that it was not possible to band at the center of the product unless the position of the band was controlled.

[Means for Solving the Problems] Therefore, in order to achieve the object of the invention and solve the above-mentioned problems, the present invention provides a method in which the packing machine performs bundling while moving forward at the same speed as the conveyor belt. , product assortment! is no longer necessary, and the ability is improved accordingly.

The first aspect of the present invention is a non-stop packaging device in which a recess is formed inside the packaging device main body to allow the packaging machine to move by a set distance, and a timing conveyor is placed just in front of the main body to control the sealing of the packing machine. A plurality of rows of 4-reto conveyors are built into the main body of the device, and the heald conveyor is located at a portion facing the seal control section. , forming a gap for the band of the packing machine to pass through, and providing a drive mechanism for running the belt conveyor inside the main body of the packing machine, and causing the belt conveyor to run when the seal control section detects the presence of the object to be packed. The packing machine moves forward at the same speed as the packing machine speed, and when the seal control section detects that the hand is wrapped around the objects being packed while moving forward and the bundling is completed, the packing machine moves backward in response to a bundling completion signal. It is equipped with a moving mechanism.

The second aspect of the present invention is that in the non-stop lump packing method, the objects to be packed that have been sent to the main body of the packing device from the previous process are placed on the supply side of the mounting surface of multiple rows of belt conveyors built into the main body of the device. When the object to be packed is detected and reaches the position of the seal control part of the mobile packing machine, the packing machine begins to move within the recess of the main body at the same speed as the belt conveyor, and at the same time, the packing machine itself starts bundling. After completing the process, the packing machine instantly begins to return to its original position,
The items to be packed that have been bundled are discharged forward, and at this time, the next item to be packed has been sent with timing adjusted from the previous process, and while the packing machine returns to its original position, it is automatically moved to the binding position. The speed of the belt conveyor is controlled so that when the packing machine returns to its original position, it moves forward again and bundles the colored objects to be packed. .

[Example of operation process]

Next, an example of an operation process in a packing operation according to the present invention will be explained.

The objects to be packed W placed on the conveyors in this order are the supply accumulation roller conveyor C2 and the timing belt conveyor C1 installed immediately before the packaging device main body 1, and are conveyed through the sensor 17 installed at the front of the timing belt conveyor. The length E in the running direction is measured, the running speed is adjusted, the conveyor is transported to the main body 1, and at the same time it is transferred to the belt conveyor 9 on the main body side, the conveyor drive mechanism 9' is driven by the forward rotation of the servo motor M. Packed as is 1
113 and reach the predetermined positions of the handway unit 4 and seal control section 5. In this case, when one band B is applied, the package is set so that it reaches the center position of the seal control section 5.

When the presence of the object W to be packed is detected at the reached position, the forward and backward drive mechanism 11 starts operating due to the forward rotation of the servo motor M2, and the packing machine 3 moves to the concave portion 1 of the main body 1. During the forward movement, the packing machine started to apply a band to the center of the object to be packed, and the packing machine reached the front position on the set moving path #L. Sometimes binding (wrapping, gluing,
Kanotov is completed.

In addition, when wrapping two bands B around the object to be packed W, the center position of the object to be packed should be located in front of the center of the seal control section 4, and after binding by hanging the first grain hunt at that position. In response to the bundling completion signal from the packing machine 3, the packing machine moves backward to the banding position of the two openings of the object W to be packed, and at the same time, by controlling the speed of the belt conveyor 9,
After determining the position for hanging the bands on the two openings, hang the bands and tie them together.

The reason for controlling the speed of the belt conveyor 9 is as follows.
By increasing or decreasing the speed of the belt conveyor 9 depending on the length P of the object W to be packed, the packing machine 3 can move two bands within a predetermined moving distance L (approximately 200 ae in the embodiment). This is to make it possible to make bets.

Next, when the seal control unit 5 completes the binding of the items W to be packed, the packaging machine 3 sends a binding completion signal, and in response to this signal, the servo motor M2 rotates in reverse, and the packaging machine 3 instantly Start moving backwards. On the other hand, the bundled objects W to be packed are moved forward by the belt conveyor 9, but when the packing machine 3 starts to move backward, the belt conveyor 9 moves to move the next object W to be packed to the predetermined position in FIG. The packing machine 3 returns to its original position by controlling the speed to change the speed so that the packaging machine 3 can supply up to 100% of the packaging material, thereby completing one process. Then, the packing machine 3 moves forward again to move the next packing object W, (hereinafter Wz ・W, . . .
. . . W, ) moves forward to a predetermined position of the seal control section 5. In this case, if there is no next item to be packed, the packing machine 3 is stopped at its original position.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following effects. In other words, even if the speed of the belt conveyor is increased,
Since the movement of the packing machine is not stopped during the bundling by the packing machine, it is possible to reliably prevent the stacked objects to be packed in multiple stages from collapsing.

Furthermore, by not stopping the running of the packing machine and the belt conveyor during bundling, the supply, bundling, and conveyance of the objects to be packed are fully automatically performed, saving labor and making the work extremely smooth.

Furthermore, the banding processing capacity can be achieved in an extremely short time by making the travel time of the packing machine the same as the banding time.

Further, positioning adjustment for size change is not necessary.

In other words, even if the items to be packaged are random products with irregular lengths, the timing belt conveyor and sensor in the previous process ensure the adjustment of the feeding speed, so that the supply speed is always adjusted properly, in addition to being loaded with one piece at the appropriate position. It is possible to perform full band binding or more band binding. Note that it is natural that products having standard dimensions with a constant length can be bound at a predetermined location.

Furthermore, the non-stop packing apparatus of the present invention does not require an overhang frame on the packing machine for attaching accessory devices, and is novel and advantageous as this type of non-stop packing apparatus and method.
