Description

Device and method for transferring tubular bag body

The invention relates to a device for transferring a tubular bag body, wherein the tubular bag system can be substantially transferred by a longitudinal transfer device in a direction in which it is longitudinally extended, and can be transferred by a transverse transfer device in a direction substantially perpendicular to the longitudinal direction. In the direction of extension, one of the conveying devices is used for conveying the tubular bag body from the longitudinal conveying device to the transverse conveying device, and the conveying device includes a bearing surface for carrying the tubular bag body.

The present invention also relates to a method for transferring a tubular bag body, wherein the tubular bag body is firstly transferred substantially along a longitudinal extension direction thereof, and is transferred to a bearing surface, wherein the tubular bag system is substantially vertical along The direction in the longitudinal extension direction is transmitted by the bearing surface.

The above-mentioned transmission device and transmission method are widely used in the art and are often used in equipment for manufacturing bag bodies, especially from woven paper. The process usually starts with a material web. The tubular bag system is separated from the textile raw material into a single unit, especially through a transverse cutting device. The tubular bag system is then forwarded in the transverse direction so as to be able to contact the open end area of the tubular bag body in subsequent production steps. According to this purpose, the prior art proposes a wide variety of various transmission devices, whereby the tubular bag body is changed in direction during transmission.

The above-mentioned device for changing the transmission direction of a flat pipe is disclosed in German Patent No. 10 2009 000 893A1. The flat pipe fittings are pushed one by one towards a bearing surface in the longitudinal direction, so as to be subsequently transferred into the transverse direction by a conveying device. Available in a flat type Before being transported in the lateral direction, the flat pipe in the conventional technology must first be located in a lateral area on the lateral transmission plane so that the lateral area can be combined by the conveying device. Therefore, when the pipe fitting is extrapolated to the bearing surface, it must be at least partially set in the area of the transverse transmission plane, so that the pipe fitting is already located on the plane before being transported. For design reasons, the transmission station in the conventional technology includes a conflicting edge, and the bag may push against the conflicting edge, thereby messing or even damaging the bag, and it is not easy to order the bag to the next step. Before delivery. In order to avoid the above-mentioned collision, German Patent No. 10 2009 000 893 A1 divides the bearing surface of the conveying device into a fixed portion and a height adjustment portion in one embodiment. The height adjustment part is formed in a plate shape and is connected to the fixed part through a steering pin, and the steering pin is actuated in the forward direction of the tube body. With the help of a reciprocating piston cylinder, the height adjustment portion can be rotated relative to the steering pin, so that the side edge of the pipe protruding from the height adjustment portion does not act against the abutment edge of the lateral transmission plane .

In addition, German Patent No. 10 2009 000 893 describes that a subsequent flat workpiece can be moved forward a predetermined distance in the longitudinal direction, and the preceding workpiece is conveyed a distance toward the transverse direction, and the value is smaller than the width of the workpiece . For this purpose, a propulsion element is provided, whereby the end of the flat tube can be pushed into the area below the plane where the end originally lay, and the area can be a side of the load plane or a free space. The propulsion element may include a compressed air piston cylinder, whereby a pusher finger or a propulsion belt may be moved. Then, the pushing finger or the pushing belt enters an area of the tube body and contacts the latter, wherein the area is not located on the plane. When the propulsion element is moved, the end of the tube is thus folded down and moved along the lateral surface of the load-bearing element containing the load-bearing surface, until the end reaches the free space and receives a restoring force to be linearly aligned again . However, this embodiment has the disadvantage that the design is expensive and not completely reliable.

Accordingly, the problems of the present invention include reducing or eliminating the shortcomings of the conventional technology. In particular, the present invention uses a device directly corresponding to the structure to design the tubular bag body from the longitudinal transfer device to The transmission mechanism of the lateral transmission device, and avoids operation failure by increasing the rate of the finished product of the bag body.

This problem is solved by the device of item 1 and the method of item 18 of the scope of patent application, and its subsidiary items describe its preferred embodiment.

The tubular bag system is conveyed by the longitudinal transfer device, especially along a horizontal longitudinal transfer plane to the transfer device, and accordingly, the tubular bag system is transferred to the horizontal transfer device so as to perform a substantially 90 degree Change of direction. The open end area of the tubular bag body is thus located on the side of the lateral transport device so as to contact the open end area of the tubular bag body in a subsequent processing station, such as a bottom opening device. According to the present invention, the transmission device between the vertical transmission device and the horizontal transmission device includes an upper bearing surface and a lower bearing surface, and the words "upper" and "lower" here refer to the operating position of the device. According to this, the tubular bag body can be alternately transmitted to the upper bearing surface or the lower bearing surface by changing the switching element during the operation of the device. The conveying device preferably includes a suitable supporting member, such as a supporting wheel, according to which the tubular bag system is conveyed from the respective bearing surface to the lateral conveying device. The tubular bag body is then conveyed in the lateral transport direction. According to the at least two bearing surfaces, a delay through the conveying device can be avoided. According to the present invention, the continuous bag body can be overlapped when conveyed on the bearing surface. According to this, the tubular bag body can be pushed to a load-bearing surface along the longitudinal transfer device, and a bag system in the front is transferred from the other load-bearing surface along the transverse transfer direction. Therefore, before the next bag body reaches the conveying device, the bag body need not be completely conveyed out by the conveying device. As a result, the number of bags of the conveying device per unit time can be greatly increased. Compared with the prior art, on the one hand, it is based on a technically simpler device. The throughput of the transfer device increases, while the separate bearing surface of the transfer device can achieve more reliable operation of the device, and disintegration can be eliminated for most parts. Of course, more than two bearing surfaces may be provided. In many applications, it is particularly advantageous if the conveying device includes at least one intermediate bearing surface disposed between the upper bearing surface and the lower bearing surface. Preferably, a plate-shaped bearing element is used to constitute the bearing surface. The bearing surface is preferably disposed on a horizontal plane; however, the bearing surface may be disposed obliquely with respect to the horizontal plane.

Regarding the embodiment for saving space, it is particularly advantageous if the upper bearing surface and the lower bearing surface of the conveying device are arranged up and down. It is preferred to provide substantially the same bearing surface (especially a horizontal bearing surface). Preferably, more than two bearing surfaces can be provided, such as three or four bearing surfaces.

In order to improve the capability of the conveying device, it is particularly advantageous if the switching element is used to alternately transfer the tubular bag body to the upper and lower bearing surfaces of the conveying device. According to this, the tubular bag system is alternately transmitted to the upper bearing surface and the lower bearing surface of the conveying device. When more than two load-bearing surfaces are provided, the tubular bag body is preferably alternately assigned to each load-bearing surface.

For the rotation of the switching element between the upper position and the lower position, it is particularly advantageous if the switching element is connected to a rotating device. By driving the rotating device, the tubular bag body can be controlled to be transmitted to the upper bearing surface and the lower bearing surface. It is preferable to establish control of the rotating device so that the tubular bag body is transmitted to the upper bearing surface and Lower bearing surface.

In order to transfer the tubular bag body to the upper load bearing surface and the lower load bearing surface, if the rotating device used to rotate the switching element can rotate around at least one rotation axis, the rotation shaft system and the longitudinal transmission It is particularly advantageous that the transmission plane of the device is parallel and extends in a direction substantially perpendicular to the longitudinal transmission direction. According to this, the switching element can be inclined upward with respect to the at least one rotation axis (particularly, the horizontal rotation axis), so as to transfer the bag body sent to the switching element to the upper bearing surface. On the other hand, the switching element can be tilted downward to transfer the bag body delivered to the switching element to the lower bearing surface.

In order for the bag body to be conveyed along the longitudinal conveying device without being hindered, if the switching element includes an upper guide and a lower guide, and a space is formed between the upper guide and the lower guide, A guide gap through which the tubular bag body passes is particularly advantageous. Accordingly, the tubular bag body can be transmitted through the guiding gap of the switching element, and the tubular bag system can be transmitted to the upper guiding surface or the lower guiding surface according to the position of the switching element.

In a particularly preferred embodiment, the upper guide includes at least one upper needle-shaped element, preferably includes a plurality of upper needle-shaped elements perpendicular to the longitudinal transmission direction and spaced from each other, and / or the lower guide Containing at least one lower needle-shaped element, preferably including several lower needle-shaped elements perpendicular to the longitudinal transmission direction and spaced from each other. In the case of several needle-shaped elements, it is particularly advantageous if the upper needle-shaped element and / or the lower needle-shaped element can be switched together, especially rotated together between the upper position and the lower position.

According to another alternative embodiment, a plate (especially a guide plate) can be used as an upper and / or lower guide, and the plate can be adjusted between the upper position or the lower position so that the tube The bag-shaped body is conveyed in the direction of the upper or lower bearing surface.

In order to change the switching element to distribute the tubular bag body to the upper or lower bearing surface, if the upper guide (particularly the upper needle element) is provided on an upper rotating shaft member, and / or the lower guide It is particularly advantageous that the piece (especially the lower needle-shaped element) is disposed on the lower rotating shaft member. The rotating shaft member is preferably connected to the rotating device so as to change the switching element between the upper position and the lower position.

In order to continuously transfer the tubular bag body to the respective bearing surfaces of the conveying device in a highly reliable manner, if an upper transmission surface rising along the longitudinal transmission device is provided between the switching element and the upper bearing surface, And / or it is particularly advantageous to provide a lower transmission surface lowered along the longitudinal transmission device between the switching element and the lower bearing surface. Preferably, a substantially horizontal and vertical transmission plane is provided, and then the transmission surface is set to the bearing surface of the transmission device. The switching element is preferably disposed in the transition area between the vertical transmission device and the transmission surface.

According to this purpose, it is advantageous if the upper transmission surface and / or the lower transmission surface are disposed at an inclined angle with respect to the longitudinal transmission plane of the vertical transmission device. Therefore, according to the position of the switching element, the tubular bag body can be guided to the upper transmission surface obliquely upward or to the lower transmission surface of the conveying device obliquely downward. The longitudinal transmission device is disposed in the vertical direction, and is preferably located substantially in the middle between the upper transmission surface and the lower transmission surface of the transmission device.

In order to achieve the distribution of the film sequence during the transition from the vertical transmission plane to the transmission plane, a wedge-shaped element may be provided according to a simple structure embodiment to form between the switching element and the transfer device. The front sections of the upper and lower transmission surfaces, and the wedge-shaped element is preferably movable (especially rotated) between an upper position corresponding to a lower position of the switching element and a lower position corresponding to an upper position of the switching element. . Therefore, when the switching element is disposed in the upper position, the wedge element is preferably disposed in the lower position, and vice versa. This has the advantage that the obstruction of the guide path to the upper or lower load surface of the conveying device can be reliably removed. In this preferred embodiment, it is particularly possible to prevent the bag body from colliding with the wedge-shaped tip of the wedge-shaped element. The switching element preferably includes the aforementioned guide, and accordingly, the bag system is particularly alternately conveyed in the direction of the upper or lower bearing surface, and the wedge-shaped element is switched between the lower and upper positions.

If an upper transmission device (especially having at least one transmission belt) is provided, the tubular bag body on the upper transmission surface is transferred between the switching element and the upper bearing surface, and a transmission device (especially having at least one (Another conveyor belt) transferring the tubular bag body on the lower transfer surface between the switching element and the lower load bearing surface of the transfer device, the transfer of the tubular bag body to each load of the transfer device can be accelerated surface.

According to a particularly preferred embodiment, the conveying device includes a pressure element in each case of the upper and / or lower bearing surface, which can be adjusted between a release position and a clamping position. By temporarily holding the bag body on the upper or lower bearing surface through the pressure element, it is possible to reliably prevent the bag body from being on the bag body during the transition from the longitudinal transfer device to the transfer device. Rise. The bag system is placed on the upper or lower bearing surface in a controlled manner through the pressure element. In addition, the opening of the body of the tube can be largely prevented from being caused by subsequent airflow. When the conveying or output position of the lateral transmission is reached, the pressure element can be raised from the holding position (holding the bag body on the upper or lower bearing surface) to the releasing position (releasing the bag body).

In order to prevent the bag body from entering the conveying device with a sharp delay, if the pressure engine element includes a pressure engine part, and the pressure engine part can be moved in the longitudinal conveying direction and preferably by a winding belt (especially around the Two deflection wheels and a looped winding belt) are advantageous. According to this, the pressing part moves together with the bag body in the longitudinal conveying direction until the bag body reaches the release position (where the bag body starts to be conveyed laterally). In this way, when the bag body is introduced into the release position of the upper or lower bearing surface, sliding friction between the pressure element and the bag body can be better avoided.

The pressing element is preferably connected to a lifting member, which can be rotated around a rotating shaft as a center, so that the pressing element is moved between the release and clamping positions. By rotating the lifting member around the rotation axis, the pressure element is changed from the lower clamping position to the upper releasing position, and vice versa.

In order to raise the pressure element before the lateral transmission starts, if the lifting member includes at least one lifting arm, and the at least one lifting arm is provided on a bearing member, particularly a cam, which is provided on another rotating shaft, Department has advantages. The cam has a non-circular or oval shape in a known manner, so that the lifting arm is set at the lower clamping position or the upper releasing position according to the angular position of the cam.

For the transition of the pressure element between the release position and the clamping position, if a linear drive (particularly an electrically, pneumatically or hydraulically actuated piston cylinder device) is connected to the reversing lever, The other axis of rotation is advantageous. By actuating the linear driving member, the other rotating shaft is rotated through the reversing rod connected thereto. The effect caused by the rotation of the other rotation shaft causes the cam provided thereon to lift the lifting arm, and as a result, the pressure element is lifted To the release position.

In order to combine the position of the pressure element with the lateral transmission device, if the other rotation shaft is connected to a contact wheel through a rotation rod, the contact wheel can be rotated to release a static position of the bag body and the bag body It is advantageous to send it to a movable position in the transverse transmission direction. In this embodiment, when the pressure element is set at the release position, the contact gear train is set at the movable position for the lateral transmission, and vice versa. Therefore, the transmission of the transmitting device can be coordinated with the pressure element.

In order for the bag body to generate the lateral transmission, it is advantageous if the contact wheel located in the movable position is lowered onto a driving wheel and the driving wheel is connected to a driving device. Due to the virtual combination between the contact wheel, the bag body and the driving wheel, the bag system is sent out from the conveying device in the longitudinal transmission direction.

In order to send the tubular bag body from the conveying device, it is advantageous if the upper bearing surface and the lower bearing surface of the conveying device are connected to a common transmission plane of the lateral transmission device through an upper and lower merging area. . Accordingly, the tubular bag system is transferred from the bearing surface of the transfer device to the horizontal transfer plane of the lateral transfer device. The tubular bag body is preferably alternately transferred from the upper and lower bearing surfaces to the common transmission plane of the lateral transmission device along the merging area. Preferably, other transmission devices (especially with a transmission belt) are provided to transfer the tubular bag body to the combining area, and the combining area can be constructed between the switching element and the transferring device. Preferably, a horizontal horizontal transmission plane is provided, which is preferably consistent with the horizontal horizontal transmission plane.

In addition, in this embodiment, it is advantageous if the upper merging area and / or the lower merging area present an obtuse angle with the transmission plane of the lateral transmission device in each case. Accordingly, the upper merged region is inclined downward and the lower merged region is inclined upward. The horizontal and horizontal transmission plane of the horizontal transmission device is disposed in the vertical direction, and is preferably located substantially between the upper bearing surface and the lower bearing surface of the transmission device.

Generally, for bag production equipment, if a separating device is provided, the tubular bag It is advantageous to separate the body into a single unit. With the help of the separating device, a tube-shaped woven material can be cut into a single tube-shaped bag body, that is, constitute an open end region. The separation device is preferably arranged in the area of the longitudinal transmission device. The woven material (after being separated into a single unit) and the tubular bag system are conveyed in the planar state, that is, the bag body portions are superimposed on each other through the longitudinal transfer device.

Preferably, a transverse cutting device is provided for cutting a tubular braided material in the transverse direction of the longitudinal transmission direction as a separating device. The above-mentioned transverse cutting device belongs to the prior art in nature. For example, a rotary blade wheel may be provided, whereby the weaving material is cut along the lateral direction of the longitudinal conveying direction.

Generally, for bag production equipment, an opening device is preferably provided to form a bottom opening between the bag body portions of the open end region of the tubular bag body. The opening device is preferably disposed in the area of the lateral transmission device, so that the bag body that reaches the planar state can be opened in the bottom area before the bottom of the bag body is formed on a bottom platform, which is also a practice in the art. know.

The method of the present invention is characterized in that the tubular bag body is transferred to an upper bearing surface and a lower bearing surface by switching a switching element, and the tubular bag body is transferred from the tubular bag body along the transverse transmission direction (extending substantially perpendicular to its longitudinal direction) Submit.

The advantages and technical effects of this method lie in the foregoing comments regarding the transfer device of the present invention.

A particularly advantageous embodiment is that the tubular bag system is transmitted to the upper bearing surface and the lower bearing surface alternately, and thus the throughput of the tubular bag body through the conveying device can be greatly improved.

FIG. 1 shows a device 1 for transporting a tubular bag 2. The device 1 comprises a longitudinal transfer device 3, according to which a tubular braided material, in particular a braided tube (not shown), is a horizontal transfer plane (i.e., extends along its longitudinal direction) along the longitudinal transfer direction 3 ' Direction) in this plane state. This woven material forms a continuous bag body 2 which is separated into single units later as described in detail below. The longitudinal transmission device 3 includes a longitudinal driving device, especially a type of a tension wheel or a transmission wheel, which is well known in the art and therefore need not be described in detail. Therefore, a separating device 5 is distributed to the longitudinal conveying device 3, and the tubular bag body 2 is formed by the knitted material through the separating device. As shown in this embodiment, a transverse cutting device is provided for cutting the tubular braided material perpendicular to the longitudinal transmission direction 3 'as the separation device 5. The transverse cutting device includes a top provided with a blade element. The rolling member 6 and a lower rolling member 7 provided with a corresponding receiving opening. The rolling elements 6 and 7 are arranged to rotate in opposite directions, so that the knitted material is cut once in a direction perpendicular to the longitudinal extension in each rotation direction, so as to separate the bag body into a single unit. A force wheel 4 is provided to stretch the braided material in the transverse conveying device. The tubular bag body 2 includes two bag body portions superposed on each other, and each bag body portion may be composed of several different material layers. Thereafter, the tubular bag body 2 is transported in the planar state in the longitudinal transport direction 3 ', The open end region of the tubular bag body 2 is disposed at the front or rear end.

As shown in Figs. 3 and 4, the device 1 also includes a lateral transmission device 8. According to this, the tubular bag body 2 is transmitted in the lateral transmission direction 8 ', that is, it extends substantially perpendicular to its longitudinal direction so as to be transmitted to a The bottom opening device (not shown) forms a bottom opening in the open end region of the tubular bag body 2. In addition, a transfer device 9 is provided to transfer the tubular bag body 2 from the longitudinal transfer device 3 (only shown schematically in Figs. 3 and 4) to the lateral transfer device 8.

As shown in FIGS. 3 and 4, the conveying device 9 includes an upper bearing surface 10 and a lower bearing surface 11 of one of the tubular bag bodies 2. This has the advantage that, for the most part, the delay of the tubular bag body passing through the conveying device 9 can thus be avoided. A tubular bag body 2 may thus have been pushed onto a load-bearing surface 10 or 11 while a front bag body 2 has not yet left the other load-bearing surface 10 or 11. In this embodiment, the upper 10 and the lower bearing surface 11 of the conveying device 9 are superposed on each other on a horizontal plane. The bearing surfaces 10 and 11 are arranged on the upper side of the plate-shaped bearing element. Of course, more than two bearing surfaces 10 and 11 may be provided.

In order to transfer the tubular bag body 2 to the upper bearing surface 10 and the lower bearing surface 11 alternately, a switching element 12 is provided, which can be changed between an upper position (refer to FIG. 1) and a lower position (refer to FIG. 2). between. In the upper position of the switching element 12 according to FIG. 1, the tubular bag body 2 is conveyed to the upper bearing surface 10, and in the lower position of the switching element 12 according to FIG. 2, the tubular bag body 2 is conveyed.系 haul to the lower bearing surface 11. According to Figures 1 and 2, several bag bodies 2 are transferred to the upper 10 and the lower bearing surface 11 one by one. However, it is preferable to alternately transfer the tubular bag body 2 to the upper 10 and the lower bearing surface 11, so that the number of the finished bag body 2 can be greatly increased.

As shown in FIGS. 1 and 2, the switching element 12 is connected to a rotating device 13. According to this, the switching element 12 can rotate around a rotation axis, and the rotation axis extends from the longitudinal transmission of the longitudinal transmission device 3. The plane extends substantially 3 'perpendicular to the longitudinal transmission direction. In the illustrated embodiment, the switching element 12 includes an upper guide 14 and a lower guide 15. A guide gap 16 is formed between the upper guide member 14 and the lower guide member 15 and allows the tubular bag body 2 to pass through. Travel in the longitudinal transmission direction 3 '. The upper guide member 14 includes at least one upper needle member 14 ', and the lower guide member 15 includes at least one lower needle member 15'. The advantageous system can be provided with several upper needle elements 14 ′ spaced from each other and perpendicular to the longitudinal transmission direction 3 ′, and several lower needle elements 15 ′ spaced from each other and perpendicular to the longitudinal transmission direction 3 ′. Rotate between the upper position according to FIG. 1 and the lower position according to FIG. 2. According to this purpose, the upper guide 14 is provided on an upper rotation shaft member 17 and the lower guide 15 is provided on the lower rotation shaft member 18, which includes a rotation axis extending parallel to the longitudinal transmission plane of the longitudinal transmission device 3 In order to achieve the purpose of changing the switching element 12.

In this embodiment, viewed from the longitudinal transmission direction 3 ', the rotation axes of the upper 14' and lower needle elements 15 'are disposed at the front end regions of the upper and lower guides 15. However, of course, the rotation axes of the upper 14 'and lower needle-shaped elements 15' can also be provided in a way that the bag body 2 first contacts the free ends of the upper 14 'and lower needle-shaped elements 15' in the longitudinal transmission direction 3 '.

As can be further observed in Figs. 1 and 2, an upper transmission surface 19 rising in the longitudinal transmission direction 3 'is provided between the switching element 12 and the upper bearing surface 10, and between the switching element 12 and the lower bearing surface 11 The lower transmission surface 20 is arranged in the vertical transmission direction 3 '. Each of the upper transmission surface 19 and the lower transmission surface 20 presents an obtuse angle with the longitudinal transmission plane of the longitudinal transmission device 3, and the longitudinal transmission plane extends horizontally in the illustrated embodiment. In this embodiment, a wedge-shaped element 21 is provided to form an upper 19 and a lower transmission surface 20 between the switching element 12 and the transfer device 9. For the transmission of the tubular bag body 2 of the upper transmission surface 19 between the switching element 12 and the upper bearing surface 10, an upper transmission device 22 is provided, which includes a transmission belt 23 on both sides of the upper transmission surface 19. In addition, a transmission device 24 is provided for transmitting the tubular bag body 2 of the lower transmission surface 20 between the switching element 12 and the lower bearing surface 11 of the transmission device 9. The lower transmission device 24 corresponds to the upper transmission device 22 and includes another transmission belt 25 on both sides of the lower transmission surface 20. The bearing surfaces 10 and 11 can be equipped with corresponding transmission devices so as to set the tubular bag body in an output position completely located on the bearing surfaces 10 and 11.

By periodically changing the switching element 12, the tubular bag bodies 2 are alternately distributed to the upper bearing surface 10 and the lower bearing surface 11 of the conveying device 9.

In the illustrated embodiment, the braided tube exhibits only a small portion of the transmission rigidity due to the improper size of the base material (such as polypropylene fibers). For this reason, it is advantageous if the pipe body portion is introduced into the lateral transfer device 8 substantially from below or above the entire transfer length of the longitudinal transfer device 3. Based on this, the non-introduced part must be as short as possible from the viewpoint of transmission.

During the transmission of the pipe body part in the longitudinal transmission direction 3 'perpendicular to the cross section of the pipe body part, the oncoming airflow may cause the risk of opening based on the required high transmission speed. Therefore, in the illustrated embodiment, the front end of the bag body portion is firmly fixed in the closed position of the entire width, which is in the transmission area transmitted to the upper transmission surface 19 and the lower transmission surface 20 Caused by the upper needle element 14 'and the lower needle element 15'. In the illustrated embodiment, the end regions of the needle elements 14 'and 15' are provided on a rising upper transport surface 19 and a lower lower transport surface 20. In this manner, the upper needle element 14 'and the lower needle element 15' exhibit a guiding function only before the front end of the pipe body portion reaches the upper transmission surface 19 and reaches the lower transmission surface 20, respectively. A gap-shaped guide channel is constructed along the upper 19 and lower transmission surfaces 20, and accordingly, the bag body 2 is guided to the upper and lower sides. Through the interaction between the guides 14 and 15 and the wedge-shaped element 21, the distribution of the bag body 2 can be achieved. The wedge-shaped element 21 defines a gap-shaped guide channel, and the guides 14 and 15 pass through Simple control to achieve guidance in this transmission direction. In this way, the bag body 2 can be reliably distributed in the directions of the upper bearing surface 10 and the lower bearing surface 11 without jumping.

As shown in FIGS. 3 and 4, the upper bearing surface 10 and the lower bearing surface 11 of the conveying device 9 are connected to a common horizontal lateral transmission plane of a lateral transmission device 8 through an upper merging area 26 and a lower merging area 27. The opening means (not shown) is used to form a bottom opening between the bag body portions of the open end region of the tubular bag body. Upper merge zone 26 and lower merge zone 27 corresponds to the upper transmission surface 19 and the lower transmission surface 20, which are constructed between the switching element 12 and the transmission device 9. According to this, both the upper merging area 26 and the lower merging area 27 present an obtuse angle with the horizontal transmission plane of the lateral transmission device 8, so that the tubular bag body 2 is inclined from the upper bearing surface 10 inclined downward and the lower bearing surface inclined upward 10 alternately leads to this common lateral transmission plane of the lateral transmission device 8.

As shown in FIGS. 3 and 4, the conveying device 9 includes a conveying member 28 (only shown schematically) for each load bearing surface 10 and 11, which is in the form of a supporting wheel.
