Description

[Detailed description of the invention] Method and device for supplying packaging materials to packaging machines Technical field The present invention is a method of supplying packaging material to a packaging machine, especially a confectionery packaging machine, At least one packaging by a take-off roll pair from at least one tape supply reel The material tape is taken off and separated into packaging material parts of a predetermined take-up length by a cutting device. One wrapping material section is fed to the wrapping operation per machine cycle, and the pre-packaging material section is The settable take-off length is controlled by a control circuit that includes the drive for the take-off roll pair. It is about how it came to be done. The invention further particularly provides the method The present invention relates to a device for supplying packaging material to a packaging machine for carrying out the operation.

Background technology According to German Patent Publication No. 3215444, packaging material tapes with printed markings are Devices for correcting and controlling the tap are known. Packaging tape is sent by pair of rolls . The drive of the roll pair is performed by a change gear device, and the connection between the change gear device and the roll pair is A differential gear is placed in between, and its rotational speed is superimposed on the replacement gear. Ru. The differential gearing is driven by a DC motor. Print marks for target values The position is determined by a photoelectric scanning head connected to a pulse generator on the single speed axis of the machine. Detected in If the position of the printing mark deviates from the target value, the rotation speed of the take-up roll will change. , by the electronic controller, through the DC motor and the differential gearing, the position of the printing mark is increased or decreased until a match between the target value and the target value is achieved. Due to dimension switching during encapsulation operation If a different length of packaging material section is required, the appropriate change gear in the change gear system will be used. must be replaced.

Therefore, the mechanical and time expenditures for size changeovers are very high. of printed images This device also meets the current requirements of the packaging industry regarding centering and length of packaging material. Do not correspond. Furthermore, if a package (packaging block) is missing from the wrapping operation section, the supply of packaging material is Special equipment is primarily required to interrupt the supply. This problem is extremely complex As such, a number of solutions are known for this purpose, in which the take-off roll one of the packaging tapes is diverted away and the packaging tape is redirected to continue picking up the packaging material. It comes into contact with the tap. The turning movement of the take-up roll mainly uses a plate cam and a die wheel mechanism. will be carried out.

Discontinuing the supply of packaging materials as described in German Published Patent Application No. 3936869 The device consists of two plate cams mounted on a shaft 180 degrees apart from each other. A lever and a control element are attached to the cam, and the packaging actuator is equipped with a lever and a control element. If there are no lumps) and therefore the packaging material section should not be fed, the lever and the control element causes deflection removal of the take-off roll. However, these devices can easily Reaching the limits of performance. In high-performance packaging machines, there are often obstacles in the supply of packaging material. occurs. After removing the take-off roll, the packaging tape will inertia due to mass inertia. Sexual behavior cannot be completely eliminated.

This results in scraps and consequent disturbances during the packaging operation. scraps In order to reduce the possibility of this occurring, the time when the take-up roll is removed and the time when it is brought into contact are as follows: The last part of the packaging material before removing the take-up roll and the first part after contact are shortened. However, this again leads to a decrease in the quality of the packaging, or Consumption increases. Although it may not be necessary when the packaging machine is in continuous operation, the packaging material section In order to shorten the time and achieve sufficient packaging of the package, Because excessive partial forms must be selected, the packaging material consumption area is arise.

This problem also appears every time the packaging machine is stopped and restarted.

Generally, it is strictly necessary that at least one of the two take-up rolls has an elastic coating. make adjustments difficult.

Device for cutting sheets from a web according to German Patent Publication No. 3114470 is known, and this web is spun from a supply roller using an intermittent drive take-off roll. It is picked up by a stepping motor.

The intermittently fed parts are cut by a transverse cutting device, which performs a pivoting movement. However, it is also driven by a stepping motor.

Furthermore, a device is provided for continuous transport of the parts.

However, this device is only suitable for packaging machines with a low number of cycles.

This device provides the necessary dynamics for synchronization during empty cycles, start-up and return. packaging in the high performance range of over 1000 cycles per minute. Not suitable for virtually continuous direct withdrawal of timber. For example, number of machine cycles 1000 cycles, part length 75rITr+, synchronizing after empty cycle A load/acceleration moment of 5 to 6 Nm appears. Stepping motor keeps pace To avoid missing a step and losing one step, the start-up frequency is set to accelerate with start-step motion. The wave number must be reduced to approximately 2 kHz. However, synchronizing and also for this Approximately 12 kHz would be required to achieve the required dynamics. At that time, Moments for accelerating the material supply reel were not considered.

In DE 31 14 470 A1, a web with an undefined starting position is wandering, accepting the well-known drawbacks of straying and, especially in the case of film, static electricity; The supply loop bypassed the drive load problem.

Disclosure of invention Therefore, an object of the present invention is to provide a packaging machine that operates continuously and has a high packaging capacity. In the packaging operation part, a part of the packaging material having a freely selectable predetermined length is inserted during the packaging operation. Always take into account the various given conditions and the unsteady state of the packaging machine. Delivered in the right length at the right time to easily prevent disruptions and loss of packaging material. The first step is to improve the type of method pointed out at the beginning.

The object of the invention is furthermore to provide for the transformation of packaging operations in an advantageous and technically simple manner. Continuously operating packaging machines, especially confectionery packaging machines, capable of meeting the demands of An object of the present invention is to provide a device for supplying packaging material to a machine.

According to the present invention, with respect to a method, the blade axis of a rotary blade of a cutting device is solved. and an increment in the rotational speed of at least one take-off roll of the take-off roll pair. are determined sequentially within each machine cycle, and are assumed to be in a proportional relationship to each other. Taking into account the circumference and the pre-selected pulling length, select The rotation value of the roll is calculated, and the take-off roll is rotated to achieve this calculated rotation value. The solution is that the drive is controlled during the next machine cycle.

With the method according to the invention, changes in the packaging process can be accommodated with short reaction times and packaging The unsteady operating conditions of the machine as well as changes in the start-up process or packaging tasks should be optimally taken into account. flexible process execution is achieved.

The desired take-off length is preferably set in millimeters by means of a digital selection switch. The rotary cutter can be selected in advance in the machine cycle. By continuously monitoring the increment in the number of rotations and the increment in the number of rotations of the pair of take-up rolls, Taking into account the diameter of the pair, the actual take-off length must be equal to the target value selected with the selection switch. Without stopping the operation of the machine, the appropriate value of the take-up roll drive speed can be brought as close as possible without interrupting the operation of the machine. This is achieved by the drive of the take-off roll without any change in the take-off length. Each change takes effect already in the next machine cycle.

One machine cycle is the time between two consecutive cutting processes of a rotary knife; During the process, the cutter performs a 360° rotational movement.

matched to the selected drawing length of the drawing roll, especially directly driven drawing rolls. The rotation speed is determined after determining the target rotation speed of the driven take-up roll of the take-up roll pair according to the present invention. (within one machine cycle) is increased if the take-up length is selected, or one Reduced if a short take-off length is selected within the machine cycle. take-up roll, (The diameter of the driven take-up roll is taken into account when calculating the target rotation speed, so the take-up roll diameter is The feeding speed of the packaging tape within one working cycle depends on the circumferential speed of the roll. It is increased or decreased until a predetermined take-up length of the dressing section is achieved.

In this way, even during size changeovers or during the wrapping operation of packages or packaging blocks of a particular size. , the length of the packaging material section is always selected according to the objectively most desirable section length. This is also easily possible for the operator of the attached packaging machine. From this, Significant packaging material savings can result, especially if the packaging material is not provided with printed markings. Ru. Moreover, all the necessary equipment is available, for example when intervening in the drive gearing. No mechanical expenditure is required.

According to a preferred embodiment of the invention, a package or a package mass is present in the wrapping operation. If it is confirmed that the packaging material is not supplied and therefore the packaging material portion should not be supplied, Starting from the moment the packaging material section is cut, a driven take-off roll is first operated for a specified period of time. is driven in the opposite direction (negative rotational value), thus pulling back the packaging tape and this The retracting path is detected incrementally by a sensor and subsequently within the same machine cycle. At this point, the take-up roll is stopped (rotation speed 0). As a result, including the collection roll Due to the mass inertia of the packaging material take-off, the packaging material tape advances out of the range of the cutting device. is pulled back and defined behind the cutting edge of the rotary tool before the start of the next machine cycle. transported to the starting position.

According to another advantageous embodiment of the method according to the invention, by driving a pair of take-off rolls, In connection with the pulling back of the packaging tape, the cutting device is rotated in a direction opposite to the normal direction of rotation. The length of the packaging material pulled back behind the cutting edge of the rotary knife, that is, the length of the packaging material tape The degree of retraction is detected incrementally, stored and added to the take-up length of the next packaging section. This is also optionally possible.

According to yet another preferred embodiment of the invention, the packaging process is interrupted and the packaging tape is removed. If the supply of packaging material is interrupted due to the inertia of the take-off device elements, including the take-off roll Coasting of the tape will inevitably occur, but for this case it is preferable to This coasting effect is achieved by incremental detection on the roll, preferably a driven take-off roll. and this value is the increment at the take-off roll at the time of cutting the preceding packaging material section. The packaging material is compared and the ratio of the actual value increment to the target value increment within the same machine cycle is This wrapping material section can be taken off at a predetermined length when the section is next cut. Compensation control is performed as follows.

A packaging machine in which a package is detected in the wrapping operation part in several consecutive cycles. In the event that the It is maintained at the state @ (rotation speed 0).

According to yet another preferred embodiment of the invention, the packaging machine advantageously During the operating process, i.e. during the start-up machine cycle, synchronization is achieved and the start-up is accelerated rapidly. In order to achieve steady-state operating conditions within the dynamic machine cycle, a pair of take-off rolls, viz. The drive speed of the driven take-off roll is already at a predetermined level on the packaging material part during the start-up machine cycle. For a short period of time, matching the predetermined withdrawal length, so that the withdrawal length of The rotation speed of the take-up roll is increased beyond the target rotation speed.

According to yet another preferred embodiment of the method according to the invention, printing on a packaging tape The position of the image is detected by a sensor using the marking line printed on the side, and The driving rotation speed is changed according to the alignment target position of the printed image based on the length of the packaging material section. will be changed.

An operating section, an adjustment device for the length of the packaging material advanced from the cutting device, and a separator. and a control device that receives sensor signals, and is connected to the drive device of the take-up roll pair. Feeding a packaging machine, in particular a confectionery packaging machine, with packaging material, preferably carrying out said method. According to the present invention, the above-mentioned problem can be solved with respect to a device for A high-dynamic drive motor is connected to the control unit and acts directly on the cutting roll. The machine has a rotary blade, and is attached to the blade shaft of the rotary blade to detect the point of cutting. The problem is solved by providing at least one sensor that

In this way, with a relatively simple structure, machine operation can be interrupted without modification. Packaging that allows you to directly change the desired take-up length without any trouble. An advantageous device is provided for feeding a portion of material to an enveloping location.

The high dynamic drive motor is preferably a service motor coupled directly to the shaft of the driven take-off roll. The rotation speed of the blade axis of the rotary cutter is the same as the machine rotation speed of the packaging machine. It is equipped with an additional incremental speed sensor attached to the cutter shaft. Ru.

Thus, changes in the length of the packaging material sections can be made at each stage of the packaging operation and by the packaging machine. During operation, packaging materials can be cut without interrupting work or changing target value settings. It is likewise possible to monitor fragments continuously. With the device according to the invention, packaging For empty cycles when loading is missing, for normal print image alignment, and for starting machine cycles. It is also easy to realize an accelerated start-up process in an advantageous manner and with high response characteristics. possible.

A second tape supply reel 6 is connected to the tape supply reel 2 for changing the packaging material. Used as another packaging tape that can be supplied in place of the packaging tape l. It is also possible to use At the rear of the pair of take-off rolls with take-off roll 4.4', A rotary cutter shaft 8 provided below carries a rotary cutter 9, and the cutter is It cooperates with the stationary knife 10. The rotary cutter 9 and the stationary cutter 10 are the packaging material tape 1 and A cutting device is formed for the inner strip 7, which tape and strip are taken together on a take-up roll 4. Feed perpendicular to the cutting device by 4°.

The gripping wheel 11 has pairs of holding arms 16, each pair of holding arms 16 The confections B are sequentially received from the individualized trays 12 and packaged in the packaging material section as schematically shown in FIG. 17 is fed from above by the cutting device 8.9.10 to the confectionery B that is just to be packaged. transported to the location where it will be.

An incremental transmitter 13 is attached to the blade shaft 8 of the rotary blade 9 that rotates in synchronization with the machine rotation speed. is provided. Furthermore, below the cutter 9 and 10 arrangement, there is a sensor for detecting each cutting point. A sensor 14 is installed. The packaging material tape 1 has a printed marking line 5 along the side edge. and the marked line correlates with the position of a suitable printed image not shown here, A printing mark scanning device 15 is provided between the deflecting rollers 3, which acts as a printing image sensor. It corresponds to Via the detection of the printed marking line 5, the rotational With respect to the length of the packaging material portion 17 cut from the packaging material tape l by the knife 9, Centering of the printed image on the packaging material portion 17 is achievable.

Inside the encasing operating part, attached to the holding arm 16 of the gripping wheel 11, from the singulation plate 12 A corresponding pair of holding arms 1 is provided in the range from receiving confectionery B to supplying it to packaging material portion 17. A sensor 18 is provided to monitor the presence of confectionery B between 6 and 6.

The drive shaft of the driven take-up roll 4° is connected to a servo motor 19 as a high dynamic drive device. Another sensor, not shown here, is directly coupled and serves as an incremental transmitter. located inside the motor.

Furthermore, a programmable control device 20 is provided, which on the one hand sensor elements 13, 14, 15, 18 and the detected actual values to the control device 20. It is connected to the incremental sensor of the servo motor 19 to Appropriate adjustments are made based on the target value. This target value is itself at least partially In particular, □Not shown here□Digital selection switch It is therefore variable in relation to the take-up length of the wrapping material section 17, which can be set manually. control By means of the device 20, the drive motor or servo motor 19 is thus activated by the take-off roll pair 4. The driven take-off roll 4'' of 4'' is controlled in such a way that the target value is achieved.

Supply of packaging material, i.e. for confectionery B held by the holding arm 16 of the gripping wheel 11 A control sequence for controlling the feeding of the packaging material portion 17 is shown in FIG. Ru. During steady operation, the confectionery packaging machine has a cycle number of 1000 to 1500 rpm or Operates in high performance range with 7 minute cycles. This number of cycles cuts the packaging material portion 17. equal to the number of separation processes carried out by the rotary knife 9 for cutting. Each machine service During a cycle (herein also referred to as a cycle), the packaging material portion 17 is separated and covered. The wrapped confectionery is also discharged from the machine. The enveloping process in the gripping wheel 11 itself takes several cycles. and is thus covered by each wrapping material portion 17 for each machine cycle. There are multiple confections at various stages of being packaged.

■The mechanical cycle includes the cutting process by the rotary blade 9 and the separation of the packaging material portion 17. After the rotary cutter 9 is rotated 360°, the next packaging material portion 17 is cut. The process ends.

As shown in the flowchart in Figure 2, even when the packaging machine is turned on (started up), the The actual state, that is, the machine rotational speed represented by the rotational speed of the cutter shaft 8, is transmitted through the incremental transmitter. 13, and the rotation speed of the driven take-up roll 4° is controlled by a servo motor 19. Scanned by installed incremental transmitters. The length of the packaging material portion 17 is controlled. On the operation panel 21 connected to the device 20, a digital calibrated in millimeter pitch is displayed. set by a selection switch and scanned by the controller 20.

Furthermore, depending on the signal of the sensor 18, it is determined whether there is a packaged mass, ie confectionery B, on the gripper wheel 11. or whether it is an empty cycle (no sugar detected). recognized. The position of the printed mark line 5 is determined by the print mark line scanning device 15 (rechargeable head). Also, the position of the rotary cutter 9 is detected by a sensor 14. ratio every l ms From the compared signal values, the control device 20 determines the required movement of the servo motor 19. The function is calculated and via the output controller 22 the servo motor 19 is The number of rotations and direction of rotation of the driven roll 4' with a rotation angle of 4.4 degrees are adjusted as appropriate.

The following particularities apply to the individual operating states: There is no condensation between the corresponding pair of holding arms 16. There is no B, therefore there is no package (package mass), and an empty cycle is displayed. If the sensor 18 confirms that the information ++J+ +, that is, "empty cycle exists" is output. Accordingly, the program of the control device 20 The output controller 22 is loaded according to the Noken installed in the ram, and the servo motor is activated. The servo motor 19 is braked to a speed of 0, the direction of rotation is reversed, and the servo motor 19 continues to operate. Stop. The return trip is detected incrementally. Length of pulled back packaging tape l is added to the subsequent take-up length of the next packaging material section 17. Optionally, preceding packaging Incremental detection of the advancing length of the packaging material based on mass inertia after separation of the material section 17 The packaging tape, i.e. its leading edge, should be cut in the defined area behind the cutting edge before the next step. It is also possible to transport it to a longer take-off length. This control process and the cutting of the next packaging material section 17 One servo motor, thus including a subsequent restart of the packaging machine, in order to release The resulting movement of the take-off roll 4.41 is clear from the curve diagram in FIG. Become. Here, 10 = start of empty cycle tl = start of subsequent cycle t2 = start of second subsequent cycle (standard operation) VSoll - set withdrawal speed +v2=maximum drive speed 1■1=Maximum reverse rotation speed This control sequence related to stopping and reverse rotation of the servo motor 19 is performed in one machine size. It must end inside the cell. During the next scan of the sensor 14, the sensor 18 is also scanned again. Confectionery B still exists between the corresponding holding arms 16 of the gripping wheel 11. If not, the servo motor position +1011, that is, the drive stop (V○) is maintained. be done. Confectionery B is present again, and therefore the supply of packaging material part 17 leads to the next packaging section Once it is confirmed that the target should be fulfilled, the “start” function is released and the servo motor is activated. The acceleration of the motor 19 is controlled as shown in FIG. 3 between times t1 and t2.

Thus, within this subsequent cycle following the stoppage of the servo motor 19, a predetermined trigger Synchronization is achieved in length. The length of packaging material missing up to the cutting edge is as shown in Figure 3. As can be seen from the startup cycle range between points t1 and t2, the take-up speed is increased for a short time, This is then achieved by returning to the target speed that corresponds to the take-off length.

Inside the process, the packaging material is The position of the printed image on the loop 1 is determined using, in particular, the side printing marks 5 and the printing marks scanning device 15. It is also possible to align accurately.

The rotation speed of the take-up roll 4.4' is corrected by the servo motor 19 in order to align the printed image. In order to This is done by logically combining the output signal of the sensor 14 that detects the point. both When the sensor signal on the other side has the value n1++, the rotation speed of the servo motor 19 is accordingly The rotation speed of the driven take-up roll 4° is then corrected to the "plus" direction. of the output signal If the logical combination yields the value +1o11, then the controller 20 causes the output controller 22 to be activated. The target rotation speed corrected to the "minus" direction for one servo motor Output.

As a result, the packaging material tape can be applied only on one side of the printed marking line 5 in the l/10 mm range. A rocking of the printed image is achieved on l. In this way, the printed image on the wrapped confectionery B The position of the sensor 14.15 determines the time cycle or mechanical cycle depending on the placement of the sensor 14.15. The reference can be fixed according to a predetermined setting value.

For example, when switching to another package or confectionery size (size changeover), the packaging material part 17 When changing the take-up length of the packaging material portion 17 or for other reasons. If it is necessary to perform A selection switch (not shown), preferably digital, calibrated to the millimeter input via the switch and thus into the control device 20. Driven take-up row The cycle is calculated by taking into account the circumferential length of 4° and also by evaluating the incremental transmitter 13 of the cutter axis 8. By counting the number of rolls and reading the selection switch value, the driven take-off roll 4 ° or for one servo motor, a new target rotational speed that determines the take-up length is controlled The output is controlled by the device 20 and the output is controlled via the output controller 22.

The relational expression is Number of cycles x withdrawal length 1−−−−−−−−−−−=number of rotations Perimeter of take-up roll When increasing the take-off length, the increase detected by the incremental transmitter 13 and the incremental transmitter The take-up roll 4 is rotated until the ratio matches the calculated value inside one servo motor. The rotation speed of the connected servo motor 19 is readjusted. When shortening the take-up length In this case, the number of rotations of the driven take-off roll 4° is reduced accordingly. Very short comparison interval Due to the distance and high incremental resolution, the required synchronization can be achieved in a short time. like this During the operation of the packaging machine, packaging operations are carried out within one work cycle (machine cycle). Any desired pick-up manager without interruption or mechanical modification. It is possible to achieve this.
