Abstract

The tape wrap machine has a rectangular frame (3,4,5) through which the items for wrapping are passed. The frame is at an angle to the item feed direction. The ends of the tape are held in a clamp (7) which is in a fixed position. The tape is fed into the frame, and tensioned by a binding head (8) on a tilt mounting. The binding head moves into the plane of the rectangular frame to feed a fresh tape into an injector slot for the frame. The head tightens the tape ready for clamping by the fixed clamp (7). <IMAGE>

Description

The invention relates to a device for strapping a packaged item by means of a belt according to the preamble of claim 1. It is a longitudinal strapping device in which the strapping plane extends in the conveying direction and a flat frame-shaped band guide channel is provided, the frame plane of which intersects the strapping plane at an angle and which is dimensioned so that the packaged goods can be conveyed through.

A device of this type is known from German Offenlegungsschrift 42 37 787, Fig. 3. The device described has a conveyor with a horizontal conveyor plane. Accordingly, there are two opposite sections of the tape guide channel perpendicular to the conveying plane on two sides of the strapping plane, while the other two sections of the band guide channel obliquely pierce the strapping plane above or below the conveying plane. A binding head is installed in the horizontal section of the belt guide channel below the conveyor level. It could also be referred to as a clamping and locking head or the like. The binding head causes the tape to be shot into the tape guide channel and the tape to be pulled back, tensioned, connected and severed. This binding head can be pivoted as an overall device about an axis, which is at the same time the intersection of the strapping plane with the frame plane surrounded by the band guide channel. The swivel drive is designed so that the binding head is in the frame plane when the band is shot in (the band track is in the frame plane when passing through the binding head) and that it then swings into the strapping plane after the packaged goods have reached the strapping position. In any case, the last phase of the retraction and possibly the tensioning process as well as the connection and disconnection of the band takes place in this position.

However, it has been shown that the entire binding head is a relatively large inert mass and it is not possible to carry out the swiveling operations so quickly that working speeds can be achieved as are required today. In addition, a swiveling binding head poses considerable design problems. The space under the conveyor level is very cramped and the moving parts and drive are extremely stressed.

The invention has for its object to provide a strapping machine of the type described in the introduction so that it works quickly and reliably with reasonable effort.

This object is achieved according to the invention in a generic strapping machine by the features of claim 1. The basic idea is to separate a part from the binding head which is capable of pivoting the belt loop from the frame plane into the strapping plane. Only this divided device, with the aid of which the band is shot and pulled back, is pivotably mounted about a pivot axis which coincides essentially with the intersection of the frame plane and the strapping plane. It guides and holds the double ends of the tape when swiveling, causing the entire tape loop to be thrown around. For this special function, the pivotable device can be made particularly light. All other parts of the binding head that perform various functions, such as. B. the holding and connecting the tape loop ends and severing the incoming tape are stationary and therefore uncritical in terms of their weight.

The strapping process takes place in such a way that the pivotable device stands in the frame plane when the band is shot into the band guide channel and swivels into the strapping plane after the band guide channel has been opened. The swiveling can take place before the tape is pulled back, as long as the tape loop is still held in the opened tape guide channel by brushing or the like. If the packaged goods are in rapid succession, on the other hand, the belt begins to be withdrawn while it is being pivoted. As soon as the band is then cut off, the mentioned sub-device can pivot back again and the next band loop can shoot in, while the strapped packaged goods are being conveyed and the next packaged goods are being conveyed into the strapping position.

It is proposed that the pivotable device has a shooting channel, the mouth of which lies in the region of the pivot axis. From the mouth of the shooting channel, the tape passes into the tape guide channel, which forms the loop around the packaged item and leads the initial section of the tape back into the area of the shooting channel mouth. As is known per se, the initial section then lies above the band section which is located in front of the mouth and has not yet been separated.

So that the doubled band sections can be moved together by pivoting the device into the strapping plane in which the components of the stationary device act on them, the two band sections must be held together so that they cannot deflect. The endless belt section is held on the swiveling device by the injection channel with a closed cross section. For the initial section returned through the band guide channel, however, it is proposed as an important feature of the invention that an intermediate clamping device is attached to the pivotable device, which fixes the initial section to the pivotable device at least until it is pivoted into the strapping plane. After clamping the end of the tape in the stationary device with greater clamping force (conventional technique), the intermediate clamping device is released again, so that the tape can be pulled back without hindrance and possibly re-tensioned without the initial section being able to free itself from the jamming.

As an intermediate clamping device, one is advantageously proposed which grips the band at the edges, ie in the direction of the band plane and transversely to the longitudinal direction of the band. Because of the easier operation the Intermediate clamping device preferably designed as a clamping lever.

Another solution to the clamping problem is, according to a further concept of the invention, that a clamping device is provided which grips the initial section of the tape in the position reached after passing through the tape guide channel on the broad sides and that at least the clamping members of this device are pivotally mounted about the pivot axis are and are in drive connection with the pivotable device. This amounts to a modification of the currently known stationary clamping device. If e.g. a slide and a plunger pushing from below on this slide are used as known clamping members, so these could each receive a rotatably mounted pressure plate, at least one of which is pivotally connected to the pivotable device, if possible via a freewheel, so that the pivotable device after cutting the tape and as long as the clamping device is still actuated, can pivot back into the insertion position.

As far as the structural design of the pivotable device is concerned, it is proposed to provide a U-shaped bracket as the supporting structure, the first leg of which is designed as a pivot arm with a strong bearing and the second leg of which supports the mouth-side section of the injection channel. This structure allows the stationary device to be gripped with the pivotable device, while the pivot axis extends through the stationary device in the extension of the axle journal.

In a first embodiment of the pivotable device, it has a feed device which consists of two or more interacting rollers which clamp the belt between them and a motor, in particular an electric motor. The rollers and the motor are attached to the pivotable device and are pivoted with it. In order to further reduce the inertial mass of the pivotable device, the motor can also be arranged in a stationary manner and be in drive connection with the feed rollers via a flexible shaft. If in any case the pivotable device has a feed unit which also feeds the tape back, it is proposed to provide a flexible tape guide channel between the pivotable device and a tape magazine (cassette). As a flexible tape guide channel, a helix tightly wound from steel wire can be considered, which can also have a rectangular cross section.

Another suggestion is that the pivotable device has no feed device at all, but rather that its insertion channel is connected to a stationary feed roller arrangement via a flexible tape guide channel. This then advantageously leads to an extreme reduction in the weight of the pivotable device and to a correspondingly simpler and faster pivot drive.

The stationary feed roller arrangement can also be designed as a tensioning device, which brings about an increased tensile force on the belt. Such a retensioning device is often provided in addition to the normal insertion and retraction device. Under certain circumstances, a flexible belt guide channel can be dispensed with if feed rollers for shooting in are arranged on the swiveling device and separate feed rollers for retracting and possibly retensioning the belt are arranged in a stationary manner.

It should be noted that the transfer of the belt loop from the frame level to the strapping level Belt guiding elements can be supported. It is proposed that in at least one guide plane perpendicular to the strapping plane and intersecting the strap guide frame, which can be the conveying plane in a vertical strapping machine, strap guide elements are provided with guide edges which form a straight slot penetrated by the strapping plane and arcuate at its ends at an obtuse angle bend towards the respective frame section penetrating the guide plane perpendicularly. The conveyor table is therefore provided with a slot which is bent twice and the respective edges of which serve as leading edges.

In addition, it is proposed that two stamps movable perpendicular to the first guide plane (for example the conveying plane) are provided, which press the packaged goods against the guide plane after reaching the strapping position and that the pressure plates of these stamps have further leading edges which are congruent with the leading edges of the first guide plane . Instead of making the printing plates from stamps to the control level, the second control level can also be stationary. In a horizontal strapping machine, both control levels are vertical. You do not need to come into contact with the packaged goods.

The invention is not limited to conventional tapes whose cross section is much wider than thick, such as. B. 5 mm x 0.38 mm. A plastic tape with these dimensions is often used to bundle magazine and newspaper packages. The term tape in the sense of the invention also includes tension cords with an oval, round or other cross section. All possible materials should also be included.

In the figures 1 and 2, the strapping device is shown in its entire extent. The belt guide frame is flat and rectangular and is perpendicular to the conveying plane 1 intended parallel to the paper plane, but obliquely to the conveying direction 2. One of the two frame sections 3 penetrating the conveying plane 1 vertically is in 1 in cross section. At the bottom, the frame sections 3 merge into short horizontal frame sections 4 over 90 ° curves. The frame sections 4 run below the conveying plane 1 and form a gap in which a stationary closure device 7 and a pivotable insertion and withdrawal device 8 are arranged. At the top, the vertical frame sections 3 are connected to one another by a horizontal frame section 5. A cuboid packaged product 9 arriving in the conveying direction 2 can move under the portal formed by the frame sections 3 and 5. The length of the packaged goods 9 is not greater than the distance between the frame sections 3 in the conveying direction 2. The packaged goods 9 are stopped in the middle under the belt guide channel. This is its strapping position.

The conveyor plane 1 comprises two horizontal plates, which together form a straight slot 1a, which extends in the middle in the conveying direction. At the ends of the slot 1a, its edge lines, the so-called leading edges 1b, bend at an obtuse angle to form a curve toward the respective frame section 3. Through the leading edges 1b, the band 13 is guided towards the slot 1a when the band loop is contracted. When the belt 13 lies against the packaged goods at the bottom, it passes through the slot 1a. Conveyor belts, not shown, which move on the conveying plane are dimensioned and arranged such that they do not cover the slot 1a and the other leading edges 1b.

There are also two stamps, not shown, arranged on both sides of the belt guide frame, which move perpendicular to the conveying plane 1 and press the packaged goods against the conveying plane. The pressure plates of these stamps also form leading edges which run essentially congruently with the leading edges 1b of the conveying plane 1. With that the Transfer of the belt loop into the strapping level in its upper area, supported above the packaged goods.

As the cross sections, in particular Fig. 3, show, the tape guide frame consists of a movable cover frame 6 and a stationary angle frame. The latter forms a flat contact surface 11 for the envelope frame and has a bevel 12 for stiffening. The envelope frame 6 is made of a cross-sectionally rectangular profile made of hard plastic and has a circumferential groove 10 on the side facing the contact surface 11. This groove encloses the band 13 on three sides. The groove 10 is covered when the enveloping frame 6 bears against the contact surface 11. This is the closed position of the tape guide frame according to FIG. 3. In a rapid movement driven by pneumatic cylinders, not shown, the enveloping frame 6 is moved a little way away from the contact surface 11 into the open position of the tape guide frame according to FIG. 4 the ribbon 13 formed freed ribbon loop.

The pivot axis 14 of the device 8 runs in the middle of the belt guide frame and perpendicular to the conveying plane. As best shown in FIG. 7, it is designed in the form of a bow. The lower leg of the bracket forms a swivel arm 15 which is mounted on a fixed bearing pin 16 by means of a stable bearing. An electric motor 18 and the bearing of a pressure roller 19 are fastened to the web 17 of the bracket, which in the example is vertically upward, with horizontal axes. The pressure roller 19 lies on the circumference of a drive roller 20 fastened to the motor shaft and thus presses the belt 13 onto this drive roller. A proximity sensor 21 detects whether the pressure roller 19 is rotating or stationary.

The upper leg of the bow-shaped device 8 (FIG. 7) is formed by an extension arm 22. It has a T-shaped support profile, Consists of a rib 23 and a flat carrier strip 24. On this a cross-sectionally closed injection channel 25 made of sheet metal runs, the inner cross section of which allows the belt 13 to pass through without hindrance, but also has no unnecessary cross-sectional play. The shooting-in channel 25 begins at the point of contact of the rollers 19 and 20 with an obliquely rising section and finally changes into a gently rising section, which ends with its mouth 26 approximately at the point where the pivot axis 14 comes up. Strictly speaking, in this example, the axis 14 passes through the injection channel 25 shortly before its mouth 26.

5 shows the pivotable device 8 in the insertion position. The injection channel 25 lies in the plane of the tape guide channel. The tape 13 comes from below in the area of the pressure roller 19 into the shooting channel 25, pushes after passing the mouth 26 in the shooting direction 27 into the left section 4 of the tape guide channel according to FIG. 2, rises in the first frame section 3 and finally comes in Channel of the second frame section 4 back to the device 8. The beginning of the band arrives above the shooting-in channel 25, runs over the superstructures of the boom 22 and the mouth 26 and, after a further short distance, actuates an electrical switch (band switch), not shown, which stops the electric motor 18 used for the shooting-in.

The abovementioned structures are a guide block 28 and a clamping lever 32 which is L-shaped in plan view. On the left side of the belt 13 - in relation to the insertion direction 27 - the guide block 28 forms a vertical wall 29. The clamping lever 32 is pivotably mounted by means of a bearing pin 33 and has on the side facing the wall 29 a groove which is somewhat narrower than the band 13. So when the clamping lever by means of a schematically indicated tension spring the wall 29 is used, he clamps the band 13 at its edges. An upwardly open, flat groove 30 is formed on the guide block 28 in the shooting-in direction of the clamping lever 32. This also guides the belt laterally.

A fixed stop pin 31 cooperates with a nose of the clamping lever 32 in such a way that, in the insertion position according to FIG. 5, the clamping lever 32 stands out a little from the wall 29 against the spring force. This and by widening the groove of the clamping lever 32 at the outlet end of the band ensures that the clamping effect is eliminated in this position. If the beginning of the band 13 now emerges from the right frame section 3 (according to FIG. 2) after it has circulated in the band guide frame, it runs through the groove of the clamping lever 32 in its release position and then through the groove 30 of the guide block 28 at a flat angle to the tapered band section below.

As soon as the beginning of the tape triggers the aforementioned tape switch and thus stops the tape drive, the tape guide channel opens and the pivoting movement of the device 8 begins, preferably driven by a pneumatic cylinder. Immediately at the beginning of the pivoting movement, the nose of the clamping lever 32 lifts off the stop pin 31, so that the spring becomes effective and the band 13 is held on the boom 22 by the clamping lever 32. This makes it possible during the subsequent pivoting of the device 8 by 45 ° to pivot both the band section which lies in front of the mouth 26 of the weft channel 25 and the overlying band beginning section about the pivot axis 14. The doubled band sections are thereby moved into the strapping plane and thereby reach the area of those organs of the stationary device 7 that the beginning of the band over the band surface Clamp tightly so that sufficient tension can be achieved when pulling back. Then the incoming strip section is then clamped off. Then the tape is cut off and then the two tape ends are connected by welding.

The clamping lever 32 is cut at an angle of 45 ° in the plan view on the outside of its angular shape. As a result of the cut surface 34 thus created, the belt 13 can free itself from the clamping lever groove when it is pulled back and placed against the packaged goods 9 when the clamping lever is pivoted through 45 °. The pivoting is achieved with the aid of a plunger 35 which is displaceable in the transverse direction in the guide block 28 and which cooperates with a rocker arm 37.

Shown in context, the individual phases of a strapping process and the associated control processes proceed as follows: First of all, it should be noted that the device 7 contains a camshaft 38 shown in FIG. 7, which, as is known per se, has an essential control function. Among other things, the camshaft 38 controls a heating tongue 36, the rocker arm 37, two superimposed horizontal sliders 39 and three vertical punches 40, 41 and 42.

After completion of a strapping process, the strapping device described is set ready for strapping regardless of whether a packaged item 9 is in the strapping position or not. For this purpose, it can be assumed that the pivotable device 8 is in the insertion position according to FIG. 5. New tape 13 is shot in by means of the electric motor 18. It enters the tape guide channel formed by the closed groove 10 via the injection channel 25 and makes a complete circulation. Finally, the beginning of the tape reaches the tape switch. This stops the electric motor 18 which Belt guide frame opened and the device 8 pivoted into the retracted position shown in FIG. 6. With the beginning of the pivoting movement, the nose of the clamping lever 32 lifts off from the stop pin 31, whereby the spring can come into effect, which pulls the clamping lever against the wall 29 and thus holds the band on the pivotable device 8. The belt loop is elastically wound by the swiveling movement, because apart from the swiveled belt sections in the lower middle area, the remaining larger part of the belt loop is still between the opened belt guide frame parts and is held there by brushes or similar elastic holders. The machine is now ready for strapping.

If a packaged product 9 now comes into the strapping position, a trigger switch is actuated which sets the first cycle of the cam control in motion. First, the end of the band is clamped against the upper slide 39 by means of the punch 40. It should be noted that this stamp 40 has a transverse opening 40a below its printing surface, which is penetrated by the incoming band 13. The insertion channel 25 partially projects into this opening with its mouth. Then the clamping lever 32 is released, that is, by means of the rocker arm 37 and the plunger 35, brought into its 45 ° position against the spring action. Then the electric motor 18 starts in the opposite direction of rotation and the tape is pulled back. The strap loop detaches from the strap guide channel and flips into the strapping plane as a result of the pretension generated by the device 8. When the band has finally wrapped around the packaged goods 9, the motor 18 and the pressure roller 19 come to a standstill, which is detected by the proximity sensor 21.

It gives the start signal for the second stroke, that is to say the second angle of rotation step of the camshaft 38.

In this cycle, the retracted end section of the belt loop is first clamped off relative to the upper slide 39 by means of the punch 41. The punch 42 then cuts off the tape with its right edge. Immediately thereafter, the device 8 swings back into the shooting position. In the meantime, the heating tongue 36 moves between the two ends of the band and heats them up. After the heating tongue 36 is pulled out again, the heated ends of the band are also clamped together by means of the punch 42 and are thereby welded. And finally all the stamps and slides move back, so that the connected belt loop is completely free and the packaged goods 9 can be transported further.

This completes the functional cycle, after which the strapping device is brought back into the ready-for-strapping position.

It now depends on the subsequent speed of the packaged goods, how long the strapping device remains in the strapping ready position. The faster the packaged goods follow one another, the earlier the trigger switch responds and, with high machine output, the belt can then be retracted during the swiveling process or, in extreme cases, at the same time.
