Description

TECHNICAL FIELD This invention relates to packaging machines, and more particularly to vacuum packaging machines for sliced meat. How to accurately place sliced meat on a belt with pockets,
When the belt and the meat on it pass through the vacuum packaging machine,
In the case of a flat plastic belt above the vacuum packaging machine, such as vacuum plastic packaging,
It must be placed in a fixed position.

BACKGROUND ART Conventionally, sliced meat is generally placed in a belt pocket or manually placed at a precise location on a plastic belt.

After the meat is sliced, it is separated, weighed, and transported to a conveyor belt. The sliced meat is fed to the end of the packaging machine and ends just in front of the vacuum packaging machine belt with a conveyor lined to hold it until it is transferred manually.

Generally, the sliced meat is fed onto a plastic belt that leads directly to the vacuum packaging machine from a conveyor above it that is connected to move synchronously with the heddle leading to the vacuum packaging machine. ing. In this case, the sliced meat is placed in the exact position of this upper conveyor, except that the meat already placed on the upper conveyor is automatically placed in place on the belt leading to the vacuum packaging machine. placed by hand.

In this way, in the current system, all sliced meat must be moved manually at some point so that it is always placed in the correct position in order to be able to be packed by a vacuum packaging machine. In need of.

(Problem to be solved by the invention) The packaging line of the present invention provides a first
a conveyor and a second carrying the goods to be packed;
a conveyor, a conveyor for transferring items from a second conveyor to a first conveyor, a device for matching the movement of the transferring conveyor with that of the first or second conveyor, and items near the lower end of the second conveyor; a first detector for detecting the first item, a second detector for detecting the item on the transfer conveyor, and a second detector for detecting the first item on the transfer conveyor.
A control mechanism of the device is configured to match the movement of this conveyor with that of the first or second conveyor so as to move them from the vicinity of the detector onto the transfer conveyor. 1
When the Jth item reaches the second detector, the transfer conveyor stops, and when the second item reaches the first detector, the Jth conveyor is resized. The present invention comprises a controller that moves a transfer conveyor in conjunction with a first conveyor to deliver a first item to a location on the first conveyor.

Often, in packaging machines, two or more items are packaged at the same time. In this case, it is necessary to have four multi-purpose conveyors lined up to supply the items to be packaged and to transfer the items while each is being processed. In such a case, the packaging line according to the invention has a third detector for detecting the items near the lower end of the transfer conveyor. Then, when the first month's item reaches the second + third output device, the second item will arrive at the second detector yc- so that later the transfer conveyor will move to 11''.
Adjust the control device so that the first conveyor stops after the first conveyor stops.

The second conveyor and transfer conveyor transfer the second item to the first
from near the detector to the transfer conveyor, and when the item of the 1st month reaches the 3rd inspection i:Ij d*, to move the transfer conveyor +h. 71+ move together. The first conveyor is stationary when the third item reaches the first detector.

In this case, after reaching this state, the relocation container is It moves together with the first conveyor. Normally, when a packaging machine packages two or more products at the same time, the items on the transfer conveyor are transferred to the corresponding yen (fc) of the first conveyor. The transfer conveyor and the second conveyor move together to transfer two or more items to the transfer conveyor before being put away.

The transfer conveyor and the second conveyor after the items have been transferred from the second conveyor to the transfer conveyor due to the relative spacing of the items on the second conveyor compared to the relative position spacing on the first conveyor. Which of the following will stop first?

Generally, the distance between the items on the first conveyor and the second conveyor is completely insubstantial in the following cases. i.e. of sufficient length to supply the appropriate number of items to be packed at intervals corresponding to the position spacing on the first conveyor when the transfer conveyor has to carry more than one item at a time. For transfer conveyors.

The transfer conveyor is separate and independent. It has a drive mechanism. It is then coupled to the first and second conveyors by conventional electrical, pneumatic or hydraulic methods so as to run at exactly the same speed as the first or second conveyor. Alternately, the transfer conveyor may also be a free-running conveyor, in which case a device for matching the movement of the transfer conveyor to that of the first or second conveyor is directly mechanically connected to the first or second conveyor by means of a clutch. It may also have a one-piece clutch mechanism so that it is coupled to the clutch mechanism.

(Structure and operation of the invention) A special example of the invention for packaging sliced meat will now be described with reference to the accompanying drawings.

This packaging line uses a slicer (1
0). The sliced meat is fed from this steeply inclined conveyor to the 'scale' (n). The scale forms a feedback loop with the slicer (1o), which cuts the meat to the correct size. Next, the sliced meat is sent to the direction straightener (12).The sliced meat is passed through the direction straightener through the three separations + jh path attached to the arranger. When each side of this arrayer (13) is filled with items, the items in the three aisles are transferred to the two storage conveyors ().
1), this array device (13) moves forward. Items in the 3 aisles are transferred from the 2 tier storage container to the internal feed conveyor (
15). It is then sent via a transfer conveyor (16) to a plastic belt (17) which runs into a vacuum packaging machine (18). This vacuum packaging machine (1
8) processes the items in each of the three aisles simultaneously. The machines can then be arranged side by side in order to be able to process two consecutive groups of three items at the same time.

The transfer conveyor (16) is a kind of subordinate conveyor,
It has a driving roller (19) connected to a double clutch unit (20). This Double Crunch 7t (20) is sold by the Simplatroll company and manufactured in Bedford, England. Inventory Ho is 17]95. This clutch unit has one /yahu1-(2]) passing through the center. This shaft is connected to a drive roller (19), and is driven by a Boo')-(22) or a pulley (23) depending on the state of an electromagnetic clutch connected in the middle. The internal feed conveyor (15) is powered by a motor (2
It is driven by a drive belt (24) from 5). Bell 1-(17) passing through the vacuum packaging machine is motor (26)

) is coupled to the pulley (22) of the Motor (2
The drive shaft of 6) is a drive bell) According to (28),
Double clutch unit (20) boo! J-(23)
is combined with In this way, when the pulley (22) and shaft (21) are connected with the clutch, the motor (2
5) drives the internal feed bell (1, 5) and at the same time drives the transfer belt (16).

Similarly, when the pulley (23) and the shirt (2]) are connected by the clutch, the motor (26)
8) and the bell + (17), and also drives the transfer conhair (16) which is moving at the same speed as the belt (17).

The operation of the transfer conveyor and the internal feed conveyor (15), the belt (17) of the vacuum packaging machine (18) will be explained in more detail in subsequent figures. In subsequent drawings, the corresponding location of the position of the item placed in Bell) (17) is indicated by the number 2''. Fia, 3~pity,
The initial condition is shown at 10, with two detectors, detector D1 at the lower end of the conveyor (15);
Detector D2 at the lower end of the transfer conveyor (16).

In Fig. 3, the first operation is shown, in which the conveyor (15) moves the article color, μ, towards its lower end.
Operate. This operation continues until the first item color reaches the point on detector D1, at which point the conveyor (
15) is stopped. This state is shown in Fiq, 4. Relocation conveyor (16),! : The conveyors (15) are now connected together and both are driven to transfer the first item color from the conveyor (15) to the transfer conveyor (j6). This state is shown in Fi (1, 5). continues moving first.In this initial state, the item μ
Pig, as shown in 6, first reaches the detector D1.

And on the transfer conveyor (16), the item color is detected by detector D2.
Keep moving until you reach . Originally, the transfer conveyor (1
In order to accomplish this in step 6), the conveyor (15) must be able to be driven independently. However, this depends on the length of the conveyor (16), on the separation of the detectors D1 and D2, and on the separation of the product ends and on the conveyor (15). In this example, in practice, the item color reaches D2 before the item μ reaches D]. When the product color reaches detector D2, the conveyor (]
6) stops. This situation is shown in Fi9.7.

The next action that occurs is Bell 1 entering the vacuum packaging machine.
- This is the operation of (17). At this time, transfer conveyor (1

15) Connect to the conveyor (15) so that they move together.

As shown in piq, Jo, conveyor (15) and (16
) both continue to move in the trench where the next item μ reaches the detector D1. Is this F? :! This is similar to the situation shown in 7 and 6. The process described in Fi, 6-9 is repeated for each item.

When the packaging machine (18) simultaneously processes two consecutive groups of items in each aisle, these two separate items are placed on the conveyor (6) so that they can be moved simultaneously into the packaging machine (18). It is necessary if they are not lined up. The operation of the transfer conveyor in this case is expressed as Fiq, II ~ piq, 2
It is shown as 2.

In this example, the second detector D2 is installed halfway down the conveyor (16) and the additional detector D3 is installed at the lower end of the conveyor (16). Product quality, group b, c is Fiv,
As shown at 17K, the first item reaches the detector DJ and is sent on the conveyor (15). At this point, the conveyor (15) stops VC as shown in Fig. 12. The conveyors (15) and (16) are then connected together to convey the first five items to the conveyor (15) and (16) as shown in Fig. 13.
15) to the conveyor (16). As soon as the item color detector is reached, the transfer conveyor (16) is sized, but the pig.

As shown at 14, the conveyor (15) continues to move until the second item μ reaches the detector DI. As soon as the second article μ reaches the detector D1, Fig. 1
As shown in Figure 5, the conveyor (15) is 11-years old. Conveyors (15) and (1,6) are then connected together again and moved together to transfer the articles μ to conveyor (16).

On the transfer conveyor (16), the quality of the first item is detected by the third detector D.
In the trench reaching 3, keep moving with Conhair (15).

As soon as this movement occurs, the transfer conveyor (16) stops. However, the conveyor (+5) continues to move in the trench where the third item reaches detector D1, as shown in Fia, 18. Next, the conveyor (16) is Fiq.

As shown at 19 and 20, at position "2" of belt (17) it is coupled with belt (17) to transfer both the left and right sides of the items from conveyor (16). As soon as the movement of bell l-(, +7) is completed, the conveyor (16) is rejoined to the conveyor (15) and both move the goods △ onto the conveyor ( 15) to the conveyor (16).Once the item E is on the detector D2
