Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guide device for use in a carton material delivery mechanism, a carton material delivery mechanism using the guide device, and a method for guiding and separating material from a stream of material in multiple rows. The guiding device of the invention is particularly suitable for guiding some materials from a multi-row material stream in a first direction and guiding other materials in a second direction.
The material flow is therefore divided into two.

In material delivery mechanisms, when the material feeding speed is very high, successive materials may come into contact with each other (i.e., the end of one material may touch the leading edge of the next material) when these materials are discharged onto the shimbling conveyor. This type of guiding device must be used to separate the materials because they overlap and are rotated or pinched (there is not enough time for them to separate and discharge onto the shingling conveyor). Must be. Known guiding devices of this type include mechanical material deflectors and vibrating roller mechanisms that direct the material alternately upward and downward.

However, this type of guiding device is not reliable. Furthermore, this device is difficult to modify depending on the shape of the material.

That is, an object of the present invention is to provide a guide device that can separate materials, perform the work reliably, and can be easily changed depending on the size and shape of the materials.

According to the invention, there is provided a device for guiding and separating materials 1, which device consists of a first conveying mechanism E and a second conveying mechanism F, which conveying mechanisms E.

In a preferred embodiment, the material is supplied in two directions from the artificial end by the first conveyance mechanism and the second conveyance mechanism.

Advantageously, each suction belt mechanism also consists of a pair of suction belts spaced apart transversely to the feed direction of the material. Furthermore, in this case each transport mechanism preferably consists of six sets of laterally spaced apart suction belts.

Furthermore, each of the suction belts is formed with a number of suction ports. The suction belts in the two sets of transport mechanisms are synchronized 1. The suction port of the suction belt is driven by the suction port of the suction belt in the first conveyance mechanism to suction and hold some of the materials in each row of materials, and the suction port of the suction belt in the second conveyance mechanism to suck and hold some of the materials. It is positioned so that the material is sucked and held.

When the apparatus of the present invention alternately separates the materials in each row, it is preferable that each suction belt is formed with an even number of suction ports, for example, each suction belt is formed with four sets of suction ports. Each set of suction ports consists of at least one, preferably two suction ports.

Further, instead of arranging the suction ports in pairs, the suction ports may be provided continuously around the circumference of each suction belt. In this case, it is preferable to provide a member for closing at least one suction port in at least one suction belt, and the suction ports of each suction belt are equally provided.

More preferably, a box-shaped chamber is provided in combination with each suction belt. A part of this chicken bar faces the associated suction belt and is closed off by a longitudinally grooved plate on the bend, and this chamber is connected to the vacuum pump via an inlet branch pipe. When each suction belt passes over the plate, vacuum is applied to the suction port of the belt.

a suction belt mechanism, each thimbling unit of the first pair of shinbling units being disposed at the downstream end of the first and second conveying mechanisms, A material delivery mechanism is provided, wherein each shinbling unit of the second pair of bling units is located at a downstream end of the first pair of shinbling units.

The invention further provides for guiding some of the materials from a continuous stream of multiple rows of materials in a first direction by means of a number of laterally spaced suction belt mechanisms; A method for guiding and separating material is provided, characterized in that the material is guided in a second direction by means of a number of other suction belt mechanisms spaced apart in the direction.

The present invention will be described in detail below based on specific examples shown in the accompanying drawings.

Refer to FIG. 1 showing the entire delivery mechanism [7] This delivery mechanism consists of a supply device A1, a guide device B provided on the downstream side of the supply device, and a pair of guide devices provided on the downstream side of the guide device H. Shinbling unit (5hinf-1tnff unt
t) C1+C2 (hereinafter sometimes referred to as the first simbling unit) and a pair of simbling units D+' and D2 (hereinafter referred to as the second simbling unit) provided further downstream of the pair of simbling units C1 and C, (sometimes called a simbling unit).

The supply mechanism A is provided to continuously deliver the carton blank 1 to the guide device B, and is composed of a large number of roller pairs 2. The feeding mechanism AFi is disposed downstream of a cutting and creasing mechanism (not shown) for cutting and creasing the carton material from the plate-like continuous web.

As shown in FIG. 2, the above-mentioned carton materials 1 are supplied to the guide device B in six rows. Furthermore, the materials in each row are alternately 1α for the right side material and 16 for the left side material. The right side material 1α is exactly the same as the left side material 1h, but is arranged so that the left side material 1h is rotated by 180 degrees. The material 1 is thus formed such that the right material 1α and the left material 1b are alternately arranged. This results in a reduction in the amount of waste that would be produced if all the blanks were preformed, such as the right-hand blank or the left-hand blank.

The guide device B consists of an upper conveyor set E and a lower conveyor set F (
(See Figure 2). There are six conveyors in each conveyor set E and F, and the guide device B is arranged such that the two conveyors in each set are laterally aligned with the ends of blanks 1 in each row of the six blanks example. ing.

As is clear from FIG. 1, the two sets of conveyors E and F are separated in their feeding direction of carton material. Each of the conveyors E and F has an endless belt 6 (sixth
(see figure). This endless belt 6 is driven by toothed wheels 4 and 5. Each of the belts 6 is combined with a box-shaped chamber 6. The inner surface of the chamber 6 is closed by a curved longitudinally grooved plate (not shown).

Conveyors E and F are configured such that each of the belts 6 passes over the plate of the chamber 6. Each of the chambers 6 is connected to a vacuum pump (not shown) via an inlet branch pipe 7 and a pair of inlets 8. Each belt 3 is provided with four suction ports 9. These suction ports 9 are provided in the same way around the belt 6, and are arranged in sets of two. Each of the suction ports 9 is formed by an opening 9a provided in the belt 3 and a washer-shaped head 9h fixed to the outer surface of the belt B. Therefore, when the belt 6 passes over the grooved plate of the chamber 6, the vacuum inside the chamber 6 is applied to the suction port 9, and the material 1 in contact therewith is firmly held by the belt. Become. Also the 6th
Referring to the drawings and FIG. 4, a disk 9c that fits snugly within the head 9h of the suction port 9 is provided, thereby maintaining the vacuum state in the chamber 6.

In this case, the belt 3 can be used by easily changing the number of suction ports 9 to be used.

The belt 6 is connected to a normal drive member (
(not shown). Furthermore, the suction ports 9 are each located on the belt 6, so that when a row of materials 1 is fed to the inlet end of the guide device B, the materials in each row are alternately conveyed by the belt 6 of the conveyor E and the belt 3 of the conveyor F. transported. Or〈1. The right-hand material 1a is conveyed by the belt 6 of the upper conveyor E, and the left-hand material 1b is conveyed by the belt 6 of the lower conveyor F. By doing this, there is no possibility that the right material 1α will conflict with the left material 1h in separation.

At the outlet ends of conhairs E and F, materials 1α and 1
b are supplied to the first simbling units c1 and C7, respectively. The shingling unit c1 and rjctu is a standard conveyor belt shingling unit, and its speed is lower than half of the inlet speed of carton materials 1α and 1b. Therefore, the shimbling units C1 and C2 act so that the leading and trailing ends of the carton materials 1α to 1b are slightly shaped.

After leaving the shingling units C1 and C7, the carton blanks 1a and 1b are transported to the second shingling units D and D2, respectively. Thimbling units D, D, are also standard conveyor belt shinbling units. This unit D, and, are at slow speed, and the carton blanks 1a and 1b each overlap here substantially over their entire length. Therefore, these two
Seed thimbling units C and D are carton material 1
This is to delay the delivery speed of α and 1b and perform preliminary overlap work. Once the blanks leave the downstream shimbling unit DI, they can easily be stacked manually or automatically.

The guiding device described above has various advantages. In particular, the apparatus is useful for separating continuous material that has been set, positioned, or printed in such a manner that it must be collected at the branch 12. Another advantage lies in the use of suction belts which act to guide the material without displacement over the entire length of the guiding device, which is not possible with devices using known baffle plates or vibrating rollers. Therefore, this guide device improves the internal operation.Furthermore, when the material passes through this guide device, 1
．． Since both ends are positioned by the suction belt, this guiding operation is performed reliably without any displacement.

This guide device described above can be modified in various ways. For example, the number of sets of suction ports 9 provided on each suction belt 6 can be varied. Each suction belt 6 can have a number of sets of suction ports 9, but typically 2, 4, 6, etc. are suitable. Furthermore, each set of suction ports 9 may consist of one or more suction ports. It is also possible to provide each suction belt B with a continuous row of suction ports 9.

In use, when the material to be guided has a special shape, many suction ports 9 are closed by the disks 9C, and only the suction ports located at predetermined positions on the suction belt 6 are used for transporting the material. The device of the present invention can be used for conveying many types of materials, and can be used in many fields, since it is only necessary to close the suction port 9 depending on the type of material.

If the device of the invention is used for guiding relatively wide materials, it is also possible to provide six or more suction belts 6 for each row of materials to be fed into the device. Similarly, if the materials to be guided are very narrow, only one suction belt 6 for each row of materials may be used.

The guiding device of the invention may also be used to separate some material from a continuous stream of multiple materials.

For example, a printing and processing unit comprising a printing roller having six circumferentially spaced dies for each row of a number of laterally spaced rows of material. When using the apparatus of the invention downstream, one die in each row would be set to print on a different material than the other two dies in that row.

In this case, one conveyor of the transport mechanism E or F is set to transport every six materials, and the other conveyor is set to transport the remaining materials. In this case 2
One material can be reliably separated from a continuous stream containing the seed material.

Furthermore, the guide device of the present invention can also be used to separate all the materials in adjacent rows from all the materials in a given row. That is, it is possible to separate a specific material from multiple rows of materials vertically, horizontally, and vertically. This is particularly useful with materials that have excessive edge-to-edge overlap.

The guide device of the present invention can also be used to separate a particular material from multiple rows of materials laterally with respect to its feeding direction. In this case, the suction belt mechanism (usually a plurality of pairs of suction belts) on each conveyor is divided transversely as well as perpendicularly to the feed direction.

Although the above-described guiding device has been described exclusively for guiding and separating materials such as carton materials, it can of course also be used for guiding and separating flat products such as printed labels.
