Definitions
- the invention relates to an automatic winding machine according to the preamble of the first claim.
- Modern spinning machines have a high output of spinning cops, which also places increased demands on the processing capacity of the downstream winding machines. It is therefore necessary to use a high degree of automation.
- JP-OS 50-136 440 describes a preparation device which is arranged at the head end of the spinning machine and searches for the thread on the cops, which are attached to arbors which are attached at equal intervals to the conveyor belt which passes the spindles of the spinning machine running.
- the time for the preparation of these cops is through the As a result of the requirements specified by the winding machine. This can result in an extremely short cycle time, which can increase the number of improperly prepared coils.
- the cycle time is also predefined in a preparation device in which the cops are guided with pallets in pockets of a transport disk.
- the cops are guided with pallets in pockets of a transport disk.
- they circulate several times, which limits the processing capacity of the preparation device.
- the object of the invention is to propose an automatic winding machine which, in its processing capacity, does justice to the high output of freshly spun cops from spinning machines.
- the cops to be prepared can be divided among the preparation devices, so that the respective dwell time increases significantly and thus the preparation success increases.
- a direct cycle time commitment can be avoided. This is achieved in that the stations of the preparation devices position the pallets with cops and the cycle time can vary within certain limits depending on the success of the thread search.
- the probability of success of the preparation can also be increased by arranging a last substation which is only used if the upstream substation has not found the beginning of the thread.
- the pallets 1 with freshly spun cops 2 reach the area of the winding machine on a feed path 3.
- all conveyor tracks are conveyor belts, of which the pallets 1 by friction be taken along, with corresponding limits.
- the conveyor belts overlap in such a way that a smooth transition into the respective branch path is possible, unless a corresponding resistance is brought up by pent-up pallets.
- the respective first sub-stages 10, 10 'and 10 ⁇ of the preparation devices are arranged so that there is a storage section in front of them, the length of which corresponds to a multiple of the diameter of the base of the pallets 1. After the respective reserve route formed in this way has been filled, the subsequent pallets are diverted to the branch line 4.
- the conveyor belt of the conveyor track 6 projects so far into the area of the junction track 4 that pallets 1 moved past on the junction track 4 are taken over into the conveyor track 6 when the storage section in front of the first substation 10 'is not filled.
- the conveyor belt which runs along the branch path 4 is narrower than the branch path 4.
- the structure of these substations can correspond, for example, to the illustration in FIGS. 7 to 9. Further explanations are still given.
- a transverse transport path 8 is arranged, which guides the cops 2 prepared along the transport paths 6 and 7 with their pallets 1 to the feed path 3 again.
- the feed path 3 merges into a feed path 9, which then leads to a delivery path (not shown) for the cops.
- the cops with their pallets then reach the area of the winding units from this supply path.
- 2 shows a variant in which the transport tracks 6 and 7 are arranged at a considerably reduced distance from the feed track 3. This is made possible by the fact that the substations of adjacent transport tracks are arranged offset to one another.
- sensors 15 and 16 are arranged on the feed path 3 and the transport path 6, which determine the respective fill level of the storage section in front of the first substations. These sensors 15 and 16 work together via control lines 14 'and 16' with switches 14 and 17. This ensures that all preparation facilities are included.
- a further variant of the invention shown in Fig. 3 shows the arrangement of sensors 18 and 20 in front of the switches 19 and 21.
- the switches are each controlled via lines 18 'and 20'.
- the sensors 18 and 20 are designed as color sensors which, for example, recognize the sleeve color of the heads 2 corresponding to a lot. Accordingly, they must be arranged at a height at which the cop 2 transported past does not have any wrapping.
- the control to certain transport lanes can be used to treat the heads of different lots differently. For example, it is possible to treat heads of a lot that are relatively difficult to prepare more intensively.
- a fourth substation 22 can be arranged, which for example preferably searches for the beginning of the thread on the head cone.
- the substation 12 ⁇ has a detector that detects the successful preparation. If this detector has not recognized successful thread preparation, the substation 22, which is otherwise inoperative, can take effect.
- a substation 22 ' which, like the substation 22, searches for the beginning of the thread on the head cone, also after the transverse transport path 8 on the feed path 3 (see FIG. 3).
- This substation 22 'could then are operated by the sensors of the substations 12 to 12 ⁇ . This would have to take into account a corresponding time delay depending on the distance of these substations from the substation 22 '.
- FIG. 4 shows a further variant of the embodiment of the invention, in which the preparation devices are arranged one behind the other, but have separate accesses 23 and 26.
- This arrangement of the preparation devices also represents a kind of parallel connection, as was described in the previous examples.
- a sensor 24 can, for example, detect the passage of a pallet 1 and change the switch in each case. As a result, one copy of the transport path 27 and one copy of the transport path 28 are fed alternately. This arrangement can be continued as desired along the sections of the winding machine. The extremely small space requirement is particularly advantageous.
- the sensor 24 which controls the switch 25 via the line 24, is also designed as a color sensor, as a result of which control depending on the batch is possible.
- FIG. 5 shows a series connection of preparation devices along the feed path 3.
- This series connection can advantageously be managed in that the positioning devices of the substations are controlled in such a way that they pass through as many pallets without positioning as preparation devices arranged on the conveyor belt are.
- FIG. 6 A particularly space-saving variant of the invention is shown in FIG. 6.
- the substations 10 ′′′ to 12 ′′′ of different preparation devices on the transport tracks 29 and 30 are combined as a unit.
- the units of the substations are advantageously active alternately on the adjacent belts.
- the corresponding feeding of the pallets into the two transport tracks 29 and 30 can be secured by a switch 31, which switches over to the other position when touched by a pallet 1.
- the pallet 1 is positioned on the feed path 3 by means of a drive 32, preferably consisting of three star-shaped friction wheels.
- This drive 32 rotates the pallet 1 with cops 2 against the winding direction of the thread, with a needle 33 resting on the cops foot.
- This needle 33 is mounted on a rotatable needle holder 33 ', which brings the needle 33 into contact with the sleeve base after positioning the cop 2. This is intended to solve an existing backwinding.
- a blowing nozzle 34 is additionally arranged so that its air jet largely coincides with the point of contact of the needle 33 on the tube foot.
- the beginning of the thread is to be searched for and detached by means of a needle 35 on the cop jacket.
- the needle 35 is analogous to the needle 33 by means of a rotatable needle holder 35 'to the cop jacket.
- a drive 36 which is designed analogously to the drive 32, also rotates the cop against the winding direction of the thread.
- the cop 2 is positioned opposite a suction slot 37 of a suction channel 40.
- the suction air removes that previously Thread end pulled into the suction slot 37. Since the suction slit extends over the head of the cop 2 to a height on the opposite side, which is in the area of the sleeve tip, the thread reaches the position shown in FIG. 9.
- the direction of rotation is reversed by the drive 41 and the length of the thread end defined in its length is loosely wound onto the sleeve tip. This winding can easily be uncovered again by an air flow in the region of the winding unit and then fed to a gripper.
- a detector 39 detects the beginning of the thread, which indicates the successful preparation of the cop for the subsequent unwinding process.
- the use of the detector 39 makes sense in the application of the present invention if a further substation, such as substation 22 in FIG. 3, is arranged downstream.
- this substation 22 is shown in FIG. 10. Based on the fact that the detector 39 has not detected a thread start in the substation 12station, the drive 42, which, like the other substations, consists of three star-shaped friction wheels, is pivoted into the region of the transport path 7, as a result of which the relevant pallet 1 is located in this substation is positioned.
- a suction bell 43 in the substation 22 is essentially effective at the cop cone.
- the main features of this substation correspond to a device for locating broken threads on a spinning machine, as is shown in DE-OS 26 12 660.
- the suction bell 43 is moved vertically by means of a threaded spindle 48, which is actuated by a geared motor 47.
- a light barrier formed from a light source 44 and a photocell 45 determines when the suction bell 43 has reached the head cone. After reaching a position in which there is only a very small gap between the suction bell 43 and the head cone, a suction air flow is generated in a suction channel 50, which flow continues into the suction bell 43. Due to the narrow suction gap, the suction air on the head cone is very effective, which means that the thread start detection rate is very high. The effect is further improved by the fact that the cop is rotated counter to the thread winding direction by the drive 42 while the suction air flow is present.
- a sensor 46 which, if the beginning of the thread is not recognized, can open a switch which is not shown and which leads to a storage path. Cops that have reached this storage section can then be subjected to manual preparation. With 49 a cutting device is designated, which cuts the thread end accordingly.
- the threaded spindle 48 can approach only one suction slot to the head cone, which can also be connected to the suction channel 113.
- the beginning of the thread can be blown into the head sleeve by means of a blow nozzle (not shown) or, for example, can be positioned at a height analogous to the substation 12 by means of the suction slot (also not shown) which, when the head is rotated by the drive 42, loosely winds above of the head cone on the head sleeve.
- a blow nozzle not shown
- the suction slot also not shown
- the transport system of the winding machine can be designed in such a way that these residual bobbins are also on the feed path 3 arrive. It is advantageous if the sensors 18 and 20 shown in FIG. 3 recognize that it is not a completely wound cop. These sensors 18 and 20 would then control the switches 19 and 21 so that the cop in question is passed into the transport path 7. This ensures that the substation 22, which searches for the beginning of the thread on the head cone, can be actuated if the preceding substations could not find the beginning of the thread.
