  It is an object of the present invention to transfer rod-like articles transported in the longitudinal direction of the tobacco processing industry from a longitudinal conveyor, which transports articles in a row in the longitudinal direction, to a transverse conveyor, which transports articles in the transverse direction. Improvement of the transfer device and method of the present invention, and it should be possible to deliver rod-like articles without obstacles or contamination.

  In the transfer area of the rod-like articles between the longitudinal transfer device and the transverse axial transfer device, the problem is achieved by providing an air curtain generating device capable of acting on or acting on blast air, which can be generated by the air curtain generating device The rod-like articles are developed by the flow direction of the air curtain generated or being directed in the opposite direction to the longitudinal direction of the rod-like articles in or on the longitudinal transfer device. A rod-like article comprising a longitudinal transfer device for transferring in a single row in succession in the longitudinal direction, and a transverse axial transfer device for transferring a bar-like article in the transverse direction, in particular a piercing drum To transport rod-like articles of the tobacco processing industry, in particular filter rods, in a transferable or delivered configuration within the delivery area on the outlet side of the longitudinal transfer device from the longitudinal transfer device to the transverse axial transfer device. Dress of It is solved by.

  According to the present invention, by arranging the air curtain generating device in the transfer area from the longitudinal transfer device to the transverse transfer device, the separated rod-like articles to be transferred are subjected to blast air and the air curtain is generated. Based on the idea that the flow direction of the blast air of the device is oriented at an acute angle to the surface of the rod-like article to be moved, opposite to the linear longitudinal transport direction of the rod-like article . For example, the flow direction of the blast air, which is opposite to the transfer direction of the rod-like articles to be delivered, decelerates the particles drawn by the rod-like articles such as charcoal particles. Because of the opposite flow direction and the generated funnel-like air curtain, kinetic energy is deprived of the particles, whereby the particles in the environment, which are transported with the rod-shaped article drawn in, have the transverse axis. This is because the continuation of the flight is blocked before delivery to the directional transfer device. This makes it possible to achieve a clean transfer from the longitudinal transfer device to the transverse transfer device during the production of the filter rods. Therefore, the degree of contamination is significantly reduced in the subsequent transfer process and the subsequent treatment process. The particles decelerated in the transfer area are easily removed from the transfer area by the corresponding suction device by not being transported together with the transversely axial transfer device with the particles drawn in by the rod-shaped articles and decelerated by the air curtain generator. It can be removed.

  In particular, the transverse transfer device is described as a penetrating drum directly adjacent to the longitudinal transfer device.

  Furthermore, a development of the device is characterized in that the separating device for rod-like articles is provided in the delivery area on the outlet side of the longitudinal transfer device, preferably on the outflow side of the rod-like articles, whereby the rod-like articles are Prior to delivery from the longitudinal transfer device to the transverse transfer device, it may be singulated or singulated, preferably in front of the singulating device with respect to the longitudinal direction of transport of the rod-like articles, preferably Just before and / or after the separating device, preferably immediately after, one air curtain generator capable of acting or acting on blast air is arranged, which can be generated or generated by the respective air curtain generator The flow direction of the air curtain, which is preferably counter to the transfer direction of the funnel-like and / or rod-like articles, respectively, with the longitudinal transfer direction of the rod-like articles in or on the longitudinal transfer device Conversely That it is directed, it is distinguished by.

The flow direction of the air curtain being acted upon by blast air and generated by the air curtain generating device being oriented opposite to the longitudinal transfer direction of the rod-like articles in or on the longitudinal transfer device; The rod-like articles are longitudinally transferred from the longitudinal transfer device for transferring the rod-like articles in the longitudinal direction in a configuration in which the rod-like articles are transported in the longitudinal direction in a row in parallel. Transverse axial transfer device for transporting rod-like articles in the transaxial direction, in particular into a piercing drum, configured to be delivered in the transfer area on the outlet side of the longitudinal transfer device from the device to the transversal transfer device. Industrial bar It is solved by a method for specifically transferring filter rods.

  In this case, according to the invention, the flow direction of the air generated by the air curtain generating device is directed to the strand surface of the rod-like article, in particular the blast air of the funnel-shaped air curtain is rod-shaped at an acute angle. Hit the strand surface of the article. In particular, the air outlet nozzles or air outlet slits of the air curtain generator are such that the individual blast air streams that flow out intersect (in theory) the projections in the center of the strand of the rod-like article before the air curtain generator. It is arranged and oriented. In this case, the (theoretical) intersection of the blast air stream flowing out of the air curtain generator is upstream from the air curtain generator at a distance of 15 mm to 40 mm, preferably 20 mm to 30 mm.

  In the drawings, the same or similar elements and / or parts have the same reference numerals, so that a new introduction is omitted.

  The figures of FIGS. 1 to 3 show a transfer device 10 for transferring rod-like articles 20 transferred in the longitudinal direction, which are arranged and transported one after the other in the longitudinal direction in the longitudinal conveyor 12. Each shows a different perspective view. Furthermore, the transfer device is provided at the end of the longitudinal conveyor 12 on the outlet side of the longitudinal conveyor 12 with a piercing drum 14 formed as a lateral conveyor, so that the rod transferred from the longitudinal conveyor 12 to the piercing drum 14 The article 20 is transported transversely on the penetration drum 14.

  For example, the longitudinal conveyor 12 is a component of a strand making machine of the tobacco processing industry, such as, for example, a cigarette strand making machine or a filter strand making machine. In this case, the piercing drum 14 is formed, for example, as a lateral conveyor which is used to transfer the filter rods to another machine, for example a filter mounting machine.

  The entry of the piercing drum 14 in FIG. 2 is omitted for reasons of clarity.

  The transfer device 10 is provided on the exit side with a pair of accelerating rollers with accelerating rollers 16.1 and 16.2 in the transition area between the longitudinal conveyor 12 and the piercing drum 14, so that both accelerating rollers 16.1, When the rod-shaped articles 20 enter between 16.2, the rod-shaped articles 20 are accelerated in the longitudinal direction towards the penetration drum 14 and thus separated.

  An air curtain generating device 30 is disposed downstream of the accelerating roller pair having the accelerating rollers 16.1 and 16.2 before the rod-like article 20 is delivered to the penetration drum 14, and passes through the air curtain generating device. The articles 20 are transported in the longitudinal direction.

  At the time of transfer of the bar-like article accelerated by the accelerating roller pair, the bar-like article 20 is transported along the guide body 18 at the outlet side, and this guide body faces the opening 32 of the air curtain generator 30. The rod-like articles 20 are transported between the guide body 18 and the air curtain generator 30.

Due to the deceleration of the particles by the blast air flow generated, the particles are decelerated and sucked, for example, by a suction device (not shown here) near the acceleration rollers 16.1, 16.2.

  Since the mouth-like opening 32 of the air curtain generating device 30 is formed as a long hole or a long hole opened at one end, a corresponding space is generated when the rod-like article 20 is transferred to the penetration drum 14.

  On the outflow side of the rod-like articles from the longitudinal conveyor 12, a holder 36 for the air curtain generator 30 is arranged. The holding part 36 (see FIG. 3) is not shown in FIGS.

  The air curtain generating device 30 is provided with the free and long hole 38, and the guide pin of the holding portion 36 can be introduced and accommodated in the long hole. This provides a lateral guide for the rod-like articles 20 transported in the longitudinal direction of the air curtain generator 30 movably arranged between the longitudinal conveyor 12 and the piercing drum 14.

  Preferably, the air curtain generator 30 is pivotable in another configuration.

  As can be further seen from FIG. 3, the side of the piercing drum 14 of the mouth opening 32 spreads like a funnel, so that the side of the piercing drum 14 of the mouth opening 32 corresponds to the longitudinal conveyor 12 of the opening 32. Greater than the side.

  All the features mentioned above, the features which can only be read from the drawings and the individual features disclosed in combination with the other features, alone or in combination, are considered to be important to the invention.
