Abstract

A transport system for taking spools of thread (3) on a conveyor from a textile machine (1) through an inspection station (26) to a final station. The textile machine has a plurality of positions (I-VIII) at which a plurality of spools are adjacently arranged one behind the other and produced in this manufacturing configuration. The conveyor between the textile machine (1) and the inspection station (26) is interrupted, the partial sections are connected by an intermediate station (11), the spools (3) are conveyed in the first partial section between their winding head and the intermediate station (11) in the manufacturing configuration or a division therein, the spools are rearranged in the intermediate station (11) to a flat configuration and transferred to an inspection carriage and the second partial section leads through the inspection station (26) to the end station. The spools can be alternative or additively arranged in a preferably vertical flat configuration before being taken to the inspection station (26), said spools being individually impaled on pins (17) on an inspection carriage which are arranged in a flat array, the pins (17), being long enough to be able to take several spools. In addition, the bearing frame is taken, when the conveyor is loaded with a layer of spools, through the inspection station (26) and finally on the existing layer of spools is laid another layer which is then taken to the inspection station (26). Besides only spools bearing the same kind of thread are laid on a conveyor.

Description

DESCRIPTION

Electric monorail system with spool transfer

The invention relates to a transport system for transporting thread spools. Such a transport system is known from EP-A 92 115 224.5 (Bag. 1943).

Several thread spools are aligned and wound up on a single spindle and then transported in this configuration (referred to as the production configuration in the context of this application) to an intermediate storage facility. The bobbins are then brought individually from the interim storage to the individual control.

However, there are transport systems for transporting thread bobbins, through which the thread bobbins are first brought from the manufacture to the individual inspection and then to a final storage facility. In this case, it is necessary to rearrange the thread spools from the production configuration in which the thread spools are aligned so that they can be checked individually. This reorganization takes a very long time.

However, there is also a need to produce a very high packing density of the coils for the end station. End storage, intermediate storage, packaging stations, loading stations or similar can be considered as the end station. The object of this invention is to quickly and effectively perform the rearrangement of the thread spools between the manufacturing or processing machine, individual control and end station so that the control device (doffer) by which the thread spool is removed from the machine does not take so long in time becomes that the operation of the machine suffers. This object is solved by claim 1 and / or claim 2. Advantageous refinements are specified in the dependent claims.

This makes it possible to solve the actual operating process from the process of rearranging the coil. The thread bobbins removed from the machine are removed from the doffer in the production configuration or part of the production configuration, i.e. H. aligned one behind the other, taken over and handed over in this form to another transport device. Only this intermediate transport device leads the thread bobbin to a reordering station, in which the bobbins are reloaded onto a further transport device - also referred to below as a check car, control transport device - and thereby rearranged into a surface configuration. A surface configuration is an order in which the coils of a production spindle are arranged one above the other and / or next to one another essentially in a common surface. The thread spools can then be moved through the control station in this form.

This gives rise to the further problem that this surface configuration has a large space requirement in the coil store. The further rearrangement according to claim 2 solves this problem. This solution is particularly advantageous if different threads are produced by several manufacturing or processing machines. According to this solution, it becomes possible to use the control transport device for the purpose of Always load the control only with coils of a certain type, the coils produced on a manufacturing spindle being arranged in a surface configuration. After the check, the used check transport device waits until bobbins of the same type are produced. These are then in turn handed over to the waiting control transport device in a surface configuration. The solution according to claim 2 is particularly suitable in combination with the embodiment of the invention according to claim 1.

In the development according to claim 4, there is a particularly favorable time and space-saving possibility of storage.

An exemplary embodiment of the invention is described below with reference to the drawings.

Show it

Figure 1 shows the map of a transport system according to the invention.

Fig. 2 is a vertical pallet, which is suitable for the arrangement of the coils in a surface configuration and for storage at the same time.

Figure 3 shows the vertical pallet of FIG. 2 with a transfer station.

In Figure 1, the machine 1 for the production (spinning machine) and / or processing (stretching machine) of threads is shown only schematically. Shown are the frames of the winding devices, which are designated with I. to VIII. In each winding machine six spools 3 are produced on a spindle 2. These coils are on an empty tube formed. It is indicated schematically that the winding machine I. has just been emptied. Therefore, only empty tubes 4 can be seen on the winding spindle. The winding machine II. Is in the winding trip. The coils are therefore still relatively small. The winding machines IV. To VIII. Are still in the winding cycle or shortly before the end of the same. In particular, the winding spindle of the winding machine V. is at the end of the winding cycle and the winding machine III. already in the phase in which half of the six finished bobbins are already loaded onto a doffer 5. It is assumed for the following description that different types of thread are produced on the spinning machine with the winding machines I. to IV. And V. to VIII. The Doffern 5 are handling and transport devices that can be moved along an operating path along the machine front. Each doffer 5 has two mandrels 6. Each mandrel 6 has the length of three coils or three empty tubes 4. the winding machine III. it is shown that the carrying mandrel 6 of the doffer is already loaded with three coils. The doffer has now been moved into a position in which its other mandrel 6 with the spindle 2 of the dishwasher III. flees. The remaining bobbins can now be pushed off the bobbin spindle by means of a push-off device (cf., for example, Bag. 906 = DE-PS 24 38 363 = US 39,74,973). The loaded doffer is then driven on the operating path 7, which is looped around the machine 1, to an unloading station 11. Here is a doffer 5.1. to see who is still fully loaded. The unloading takes place on an intermediate transport device 8. This intermediate transport device is configured similarly to a doffer 5. That is, the intermediate transport device has mandrels 9 which have the same distance and the same length as the carrying mandrels 6 of the doffer. Therefore, by means of a suitable push-off device (see e.g. DE- OS 42 14 229 - Bag. 1919) on the doffer 5.1. located coils are pushed or pulled on the mandrels 9 of the intermediate transport device in a very fast operation. The intermediate transport device 8 can be moved with some others on an intermediate track 10, which in the present case is self-contained and is part of a track leading to the control station. The intermediate web 10 leads to a transfer station 12. At the transfer station 12, the coils are pushed off the intermediate transport devices and thereby brought into a different configuration. This is explained again below: The thread bobbins are in the so-called "production configuration" on each winding spindle. In this configuration, the coils are aligned. In the sense of this application, the manufacturing configuration is also retained when reloading onto the doffer, since the manufacturing configuration - namely the aligned arrangement of the coils - is only shared. The maintenance of the manufacturing configuration or a part thereof has the advantage that the bobbins can be pushed off their respective winding spindles very quickly, with a single division of the manufacturing configuration only one doffer movement, with division of the manufacturing configuration (three aligned Coils) only two doffer movements are required to accommodate all coils. This short period of time is important because the winding machine - such as. B. out of the bag. 1670 = EP 0 374 536, has a winding turret with two winding spindles, the winding spindles operating alternately. The bobbin change must take place very quickly so that the newly placed empty tubes with the rapidly growing new bobbins do not grow against the full bobbins and blow up the winding machine. Because the undivided or divided production configuration with several aligned coils is retained even when the doffer is unloaded in the unloading station 11, the doffer is Lich only used briefly. This has the advantage that every doffer is available again for the actual machine operation after a short transfer time. This can save doffer. This is important because the doffers are complicated devices and in particular also contain devices (not shown here) for the supply of empty tubes (not shown here and not described).

In the transfer station 12, a sorting device 13 takes over the removal of the full bobbins from the intermediate transport device 8.1 and the loading of the control transport device 14.

Such a control transport device is shown in FIG. 2 and FIG. 3 in the top view and in the view. It is a standing pallet. The pallet (vertical pallet) has a horizontal base 15 with a vertical pallet wall 16, which is fastened upright on a longitudinal edge of the base. On the pallet wall 16 are several, for. B. six, mandrels 17 attached cantilevered vertically. The outside diameter of the mandrels 17 is smaller than the inside diameter of the sleeves for the coils. The support mandrels 17 are arranged in a surface grid. A grid of three vertical and two horizontal rows is shown. Each mandrel 17 has the length of several coil sleeves, here three coil sleeves. It is shown in FIGS. 2 and 3 that the coils delivered in the partial manufacturing configuration are distributed to the mandrels 17 in the transfer station 12 by a sorting device 13. This is done by placing a coil on each of the mandrels, the coil being on the front end of the respective mandrel.

In this way, the coils from the production configuration rearranged into a surface configuration. In this surface configuration, the coils are moved in the control direction. There they can be passed through a weighing device (see e.g. Bag. 2051 = DE-A 42 38 160) and subjected to other visual or other controls.

Each vertical pallet is independently stable on its floor 15 and can be transported on a hanging conveyor 18. Such a overhead conveyor has horizontally discharging support arms 25 with which it engages under the bottom of the vertical pallet.

The overhead conveyor can be moved on a control track 19 to the control station and then to the warehouse 21.

After the check, however, the overhead conveyor 18 initially travels with the bobbins into a waiting loop 20. The overhead conveyor 18 remains there until bobbins of the same thread type are produced and are brought into the transfer station 12 by one of the intermediate transport devices 8. Now the waiting overhead conveyor is also moved into the sorting device 13. The freshly delivered spools are pushed onto one of the mandrels 17 of the vertical pallet. The coils already on it are pushed one place further. The newly delivered coils are now also in a surface configuration, so that they can also be weighed in the control station and checked in some other way.

After the check, the overhead conveyor moves with the vertical pallet again into the bypass 20 and waits as shown. In the meantime, bobbins of different provenance can be conveyed through the intermediate transport devices 8 to the sorting device 13 and there to other lowering devices. legal palettes are rearranged.

If bobbins of the same type of thread are again delivered, the overhead conveyor 18.2. with the coils on it again moved into the tube loading station 13. The mandrels 17 of the vertical pallet are again equipped with one coil each. As a result, the newly delivered coils are again in a surface configuration so that they can be checked.

After the check, the now fully loaded overhead conveyor with the coils is moved to an end station. The storage 21 with the transfer station 22 serves as such end station. In the transfer station 22 for FIG. 3, the above description of FIG. 2 applies. In addition, however, in FIG. 3 the sorting device 13 of the sorting station - in FIG. 3 with the Letter A denotes - shown. A detail of the sorting device 13 results from the section in FIG. 3A. The supervision according to FIG. 3 shows that the sorting device has a vertical support 27. The carrier 28 is rotatably mounted on the support 27. Two mandrels 29 are attached to the carrier 28. Both mandrels have the same design and are offset by 180 °. The mandrels have an outer diameter that is smaller than the inner diameter of the sleeves. The mandrels are hollow and have a slot 30 on their upper side, which is aligned axially parallel and extends essentially over the entire usable length of the dome. A telescopic cylinder 31 is mounted in each dome. On the piston rod, which is moved by the telescopic cylinder, there is a push-out pin 32 which projects through the slot 30 and engages behind the sleeves 4 of the coils 3. The stand 27 is set up in a stationary manner at the transfer station 12. For re-sorting, the overhead conveyor 18 is moved in such a way that one of the support domes 17 of the intermediate transport device 8 alternates with one of the mandrels 29 of the sorting device 13 are cursed. The coils 3 are then pushed off the respective dome and pushed onto the mandrel 29. The carrier 28 is then rotated until the next empty mandrel 29 is aligned with the next still full mandrel 17 of the intermediate transport device 8. Then the remaining coils are pushed by the intermediate transport device 8 onto the empty dome 27. The intermediate transport device can now move again. The carrier 28 is now brought into alignment with the spikes 17 of the pallet wall 16. The control car is moved sideways step by step so that one coil each can be brought from the dome 29 to one of the dome 17 of the control car. In Fig. 3 it is shown that the control car 14 is already equipped with a layer of coils. A coil is still missing in the second layer. The carrier 27 can also be moved in the vertical direction by means of a hydraulic cylinder, which is not shown here. In order to bring one mandrel of the sorting device 13 into alignment with a dome of the vertical pallet, the control carriage 14 is moved laterally and the sorting device is moved in the vertical direction.

Here the coils are loaded onto a storage device 23. This is done by pushing the vertical pallet, which can stand on its own, onto the storage device. The storage device 23 can then be moved on rails 24 along the storage front. It is set up so that the vertical pallets can be placed on the individual shelves of the warehouse. Here again, the bobbins become more expensive according to the type of thread produced. On the shelf warehouse 21.1. So are coils, e.g. B. the processing machines I., II., III on the shelf warehouse 21.2. Spools of the winding machines IV., V., VI. and on the shelf 21.3. Spools of winding machines VII. And VIII. Stored. There, the vertical pallets can be transported using suitable transport equipment picked up again and sent for further processing.
