Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to an air distribution device comprising one or more connection points arranged in a casing and a movable pneumatic device assigned to the connection points. Concerning a type of device that is equipped with a consumption machine.

PRIOR ART In pneumatically driven tools arranged in piston units of pneumatic cylinders without piston rods, when distributing or supplying air for driving the tool, it is necessary to use an air hose in the form of an air hose for the tool. A flexible supply conduit is required. Since the tool arranged in the piston unit travels a correspondingly long distance with a possible cylinder design length of 7 m, a constant supply of air to the tool is necessary to ensure that the tool is supplied with air from a source of pressurized air that makes this working process possible. A long air hose is required that extends to the supply.

In order that such long flexible energy conduits can be installed in a suitable manner, for example cable tensioning devices are mounted or suspended, which in addition to the electrical wires and the hydraulic energy conduits can contain e.g. More pneumatic conduits of compressed air hoses are also arranged.

In particular with such devices for guiding or holding energy conduits such as hoses, in addition to the material costs of the compressed air hose reservoir, temporary structural costs are expended in order to guide the compressed air hose in an orderly manner. must be done. In addition to this, the movement course of the tool itself or the handling and movement of the material to be processed is often also impeded by compressed air hoses and holders, so that in some cases damage to the hoses cannot be avoided, so that especially In order to avoid such damage and ensure reliable guidance of the hose and freedom of movement of the tool and the material to be processed, special construction is required. Also, hoses can often be kept away from heat or aggressive media only at high cost;
Overcoming or eliminating the above-mentioned disadvantages is only possible through special and expensive construction of the hose itself.

Therefore, it is an object of the present invention to provide a device which avoids the above-mentioned disadvantages and which allows for a simple and reliable air distribution.

In order to achieve this object, the invention provides that, in an air distribution device of the type mentioned at the outset, the housing and the consumer are connected in series to a single supply line.

In a preferred embodiment of the invention, the housing is constructed as a pneumatic cylinder without a piston rod, in which the piston forms a structural unit with the consumer, and the air supply to the consumer is provided. A passageway extends from the casing. In a further embodiment, the housing is constructed as a pneumatic cylinder without a piston rod, on which one or more sliding elements are movably arranged, thereby forming a suitable air chamber. and the slide members form a structural unit together with the consumer, and each air supply channel extends from each air chamber to the consumer, in which case each slide member forms an air supply channel leading to each consumer. In addition, there are separate air supply passages for ventilating the adjacent air chambers. In a preferred embodiment, the consumer is a pneumatic tool, such as a rotating circular cutter, which is suitable for transversely cutting the strip of material.

Effects of the Invention With an air distribution device constructed in accordance with the invention, a hose-free air supply allows for an inexpensive form of drive of pneumatic tool sumps, in which case all of the above-mentioned problems associated with known flexible hoses are avoided. Shortcomings are avoided.

Example The invention will now be described in detail with reference to the drawings.

In FIG. 1, a commercially available pneumatic cylinder 1 without a piston rod is shown as a casing, and this pneumatic cylinder 1 mainly consists of a cylinder tube 2, bottom members 3, 4 and a piston unit 5. . The bottom parts 3, 4 are provided with connections 6, 7, which ensure air supply and air evacuation.

The piston unit 5 consists of a piston 8 and a force transmitting member 9, which forms a unit with the piston 8 by means of a slit 10 in the cylinder tube 2.

The force transmitting member 9 has a pneumatic tool 11 as a consumer.
The pneumatic tool 11 in this case consists of a cutter holder 12, a pneumatic cutter drive 13, and a rotating circular cutter 14. In order to seal the air-supplied cylinder chamber 15.24 in the area of the slit 10, an inner and an outer sealing band 16.17 are provided, both sealing bands being raised and lowered by the piston unit 5. Each piston 8 has a passage 18 extending from both piston surfaces.
．． 19 is provided, both roads leading to the cutter drive 13 via a force transmission member 9 and a stationary conduit 22,25.

FIG. 2 shows the pneumatic cylinder 1 and pneumatic tool 11 shown in FIG. 1 in a sectional view taken along line 2--2. As can be seen in FIG. 2, the passage 18 extends from the center point of the piston 8, bypassing the inner sealing band 16. In the upper part of the force transmission element 9, the channel 18 leads to an air distributor 20, to which the cutter holder 12 is fixed. Since the seal plate 21 is tightened between the force transmission member 9 and the air distributor 20,
Air losses in the transition region between the channel 18 and the conduit 22 are avoided O. The operating mode of the device described above is as follows: Compressed air is supplied to the pneumatic cylinder 1 via the connection 6.
When supplied, the cylinder chamber 15 is filled and the piston 8 together with the pneumatic tool 11 is moved in the direction of the arrow 23.

At the same time, a portion of the compressed air flows from the cylinder chamber 15 through the passage 18 and the conduit 22 into the pneumatic cutter drive 13 and drives the circular cutter 14 in a clockwise direction. The above-mentioned movement separates the strip of material M. During the forward movement of the piston 8 in the direction of the arrow 23, the air is
Compressed air escapes through the connection 7 from the cylinder chamber 24 which is not supplied with compressed air. The compressed air supply to the pneumatic cylinder 1 is replaced for the next cutting operation. That is, the compressed air now enters the cylinder chamber 24 through the connection 7,
The piston 8 is moved in the direction opposite to the arrow 23. In this case as well, compressed air flows from the cylinder chamber 24 to the passage 19.
and through the conduit 25 into a pneumatic cutter drive, which causes the circular cutter 14 to rotate in a counterclockwise direction and cut the strip of material M anew.

The air distribution device shown in FIG. 6 is constructed in the form of a pneumatic cylinder without a piston rod. In this case, the housing 26 of the air distribution device is formed by a slotted pipe 27 and a pipe chain 28, 29 in each case. The slitted pipe 27 is provided with a plurality of sliding members 30, 31, 32, which are connected to the pipe 2 via intermediate members 33, 34, 35.
It is connected through a slit 39 to each one consumer 36, 37, 38, which is arranged outside the housing 7. Each consumer 36.
37.38 have separate drives 40, 41.42, each of which cooperates with a rack 43, for example, and thus allows an individual movement of each consumer 36, 37.38. Make it. The casing 26 is a sliding member 30.31
．． 32 into several air chambers 44, 45, 46.47, in which case in each sliding member 30, 31.32 each air supply passage 4B, 49.50 is divided into several air chambers 44, 45, 46.47 by each consumer 36, 3
This makes it possible to supply air to 7°38°. For ventilation of the mutually adjacent air chambers 44, 45, 46, 47, the air supply channels 4B, 49.50 are extended in the direction of movement of the slide members 30, 31.32, so that the air supply channels 4
In addition to 8, 49.50, another air supply passage 51, 52.5
3 is formed.

In order to seal the slot 39, inner and outer sealing bands 54,55 are provided, based on the form of a pneumatic cylinder without piston rod, both sealing bands 54,55 being connected to the sliding member 30, in the area of each consumer. 31
．． It is raised and lowered by 32 intermediate members 33, 34, and 35. Due to the special arrangement of the upper part of each air supply channel 4B, 49.50, the inner sealing band 54 is bypassed and the respective intermediate member 33, 34.35 and the conduit 56,
Air supply to each consumer 36.37.38 is possible via 57.58. For example, the sliding member 30 and the intermediate member 3
3 and the consumer 36 can be compared with the step view in FIG. 2.

The operating mode of the embodiment shown in FIG. 6 is as follows: When air is supplied via the connection 59 in the tube-to-tube chain 28, the entire casing 26 is vented. At this time, all the air chambers 44, 45, 46° 47 are uniformly filled with air.

Compressed air can now be optionally removed at each sliding member 30.31.32. Compressed air can be taken out at any point in the range of several air chambers 44, 45, 46, 47 in each case, since the sliding elements 30, 31, 32 can be moved by the drive 40, 41, 42. can be done.

The air distribution device shown in FIGS. 1 and 2 uses a pneumatic tool in the form of a rotating circular cutter (the circular cutter axis and the direction of movement of the piston are located at right angles to each other). The air distribution device shown in FIG. (located parallel to the direction of movement of the sliding member) can be used to cut a running strip of material into strips of different widths.
