Abstract

A combined filtering stick with insertion of a circular disk made from paper or a board in a filtering part is produced in process as follows: a material belt is output at the position that the circular disk is cut down at a first suction roller. A second suction roller is used to receive the flow of the circular disk. In order to transmit circular disks and insert the circular disks into the gap of a filtering component in axial moving, epicycloids or other similar delivery mechanisms are employed to match the speed of a transmission machine with that of a roller and the filtering component.

Description

The processing of combination rod

The present invention relates to make up the production of rod, particularly relate to the equipment of the used bar-shaped filter element of combination of the production that is used for being assembled in cigarette with filter tip.

Know that the combination filtering material contains the rod type element that axially forms a line, this element has the quite element of thin similar disk between adjacent two end faces that are placed on element, that is disk is clipped between the element.Typically, disk is to be made the aperture that has one or more permission cigarettes to pass through on it by card or the same material of similar paper.

From one aspect of the present invention, produce the equipment of combination rod and form by following array apparatus, on the direction that is parallel to the club body length, feed the device of a series of bar-shaped object, described logistics leaves between continuous object at interval; Carry the device of disk stream and be used to receive disk to reach the conveyer that between continuous bar-shaped object, inserts disk, like this, can be formed on the combination rod that accompanies a disk between two continuous objects.

Preferred conveyer can change speed, and like this, when certain position, its speed is complementary with the device that is used to feed disk, and when another position, its speed is complementary with the device that is used to transmit bar-shaped object.Conveyer can comprise a planetary mechanism that is used for this purpose.In preferable a setting, conveyer comprises a series of disk joint element, for example comprises a pin that matches with the hole on each disk.

This equipment also can be included in the device that produces the gap between the bar-shaped object of applying.Like this, can from the rod that cuts away continuously, object be transported, for example form the part that filter stick is produced machine.

Disk can downcut from a material band.Conveyer can receive the disk of self-suction cylinder, and disk transmits on the suction cylinder, and is resisted against with big face on the surface of cylinder.After can or receiving before each disk is received by conveyer adhesive is coated onto on one or two surface of this disk.

After inserting disk between two bar-shaped objects, object and disk form joint by deceleration and other action of object, so that form a continuous combination rod.Bonding plane between disk and the bar-shaped object is enough to keep the complete of combination rod; On the other hand, rod can packaged and sealing in continuous baling press.By at cutting combination rod on the position between two disks, can downcut one or more combination rod type elements from making up rod.Cutting also can be undertaken by continuous incision rod.Using continuous excellent cutting equipment, two such cutting equipments can be positioned on the straight line from the place that continuous rod downcuts bar-shaped object.

Only further describe this invention by the reference accompanying drawing in the mode of example.Among the figure:

Fig. 1 is illustrated in and is used to be assembled into the disk that inserts between the filtration members of cigarette filter;

Fig. 2 is the side view of the equipment of production disk shown in Figure 1;

Fig. 3 is the plane that is used for the equipment between the filtration members that disk is inserted.

Disk 2 shown in Figure 1 is formed by the paper or the card of about 0.2 millimeters thick, and its typical diameter is about 8mm, has a diameter to be about the centre bore 4 of 2mm on it.

As shown in Figure 2, the card band 6 that gets off from cylinder 8 unwindings is sent on the benchmark cylinder 10, and benchmark cylinder 10 forms suction by a fixing aspirating air pipe 12 on the part of its circumference.Cutting-cylinder 14 matches to merge with benchmark cylinder 10 cutting knife is housed, and these cutting knifes downcut disk 2 from card band 6.Remaining card band 6A passes through part cutting-cylinder 14, and moves the garbage collection station to by a pair of opposed roller 16.The waste material that produces by forming hole 4 is removed (beginning to rest on the cutting-cylinder 14) by suction.

Benchmark cylinder 10 is sent to disk to a series of disk 2 will be sent to place on the cylinder 18, and disk 2 is retained on the benchmark cylinder 10 by the suction that applies by suction pipe 12; Similarly, conveying roller 18 cooperates with suction channel 12 disk is stopped thereon.The rotary speed of conveying roller 18 is faster than the speed of benchmark cylinder 10, so that after transmitting, disk 2 is separated further.Disk 2 is when being transmitted by conveying roller 18, and the outside of each disk 2 applies binding agent by rubber roll 18.

Each disk 2 is peeled off conveying roller 18 at delivering position 18A place by the pin 24 that engages with disk by centre bore 4.Pin 24 is contained on the planet connecting gear 26.Connecting gear 26 transmits pin 24 at each swing circle with different speed: at position 18A place, the speed of the disk 2 on the speed of pin 24 and the conveying roller 18 is consistent.

Equipment shown in Figure 3 can be used as for example part of the continuous filtration rod production machine of Molins PM5.As shown in the figure, the continuous filtration rod 28 that will be formed by cellulose acetate usually by continuous excellent cutter 32 cuts into the filter element 30 of presetting length.The filter element 30 of adjacency flows to position 36 by conduit 32 from cutter, in this position, engages each elements on either side by accelerating pulley 38, makes continuous element produce a little interval.

Conveyer 26 drives each pin 24 by position 36 with this form, makes continuous disk 2 be inserted in two slits between the continuous element 30.36 speed and the speed of element 30 are complementary pin 24 in the position.Forming from disk 2 thereon by the path of the transmission of cylinder 18 beginnings of cross drive and the unit 30 that disk 2 axially transmits thereon, and when the speed of coupling on the corresponding delivering position, connecting gear 26 in principle with BP No.2079134 or 2217574 in the principle that embodied in the disclosed mechanism similar.Transmitting machinery also will be equipped with continuous disk 2 is taken off and sends into the cam mechanism (not shown) the conduit 34 of 30 of elements or cooperate with it from pin 24.Though not expression among Fig. 3,, two interelement gaps of continuous filtration are enough to insert disk 2.

The stroke that begins from delivering position 18A, the disk 2 that has bonding agent is coated onto glue on its other one side by another gluer (not shown).In the position 36 and wheel 38 downstream, element 30 has formed the materials flow that links to each other with disk 2, and heater 40 around conduit 34 so that connect glue between disk 2 and the element 30 and dry and solidify.Can also guarantee that disk 2 and element 30 recline in the upstream of heater 40 by friction or other method.

The continuous rod of Chan Shenging is by a further continuous excellent cutter 42 like this, this cutter in the position 44 place's cutting rods to produce the combination filter element 46 that each all contains disk 2.In order to replace cutting unitary element 46, cutter 42 can be cut into the element (as comprising 4 or 6 elements 46) of a plurality of length, and to offer the filter assembly machine of producing cigarette with filter tip, this cigarette comprises one section tobacco and an element 46.

In order to be increased in the integrality of the continuous rod that cutter 42 downstreams form, can before cutting, the wrapping paper with porous be packed and seal by rod continuously.In this case, heater 40 has not just needed (although the different heater of needs is used so that gelling is solid, the continuous packing of formation is excellent sells with whole rolling out).
