Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides for transporting fiber bobbins from a vibrating conveyor.
The present invention relates to a method and a device for conveying individual fiber bobbins to a preferably regularly operating bobbin conveyor with transport pockets.

Vibratory conveyors are known to be operated irregularly, even when the objects to be conveyed consist of small articles, so that the large amount of objects to be conveyed is to some extent evened out. Therefore, it is difficult to deliver fiber bobbins from a vibrating conveyor to a bobbin conveyor that is operated at regular timings. In this case, the fiber bobbins must first be individualized before being sent out, but this individualization may be affected by problems such as binding of bobbin threads, indiscriminate mixing of bobbins with different winding amounts, and irregular positions of the bobbins. precluded by the condition.

The object of the invention is to make it possible to transport fiber bobbins from a vibratory conveyor to a bobbin conveyor, which is advantageously operated at regular timing, without any hindrance and in accordance with the working speed of the bobbin conveyor. .

According to the present invention, this problem can be solved in the first claim.
This problem was solved by the method described in Section 1. Advantageous embodiments of this method are described in the claims 2 to 4. Furthermore, the features of the device for carrying out the method of the invention are set out in claim 5. Claims 6 to 11 describe advantageous embodiments of the device according to the invention.

According to the invention, a detector, preferably a photoelectric barrier, detects whether untransported fiber bobbins, for example cots, are present at the bobbin delivery point at the end of the conveying track of the vibrating conveyor. If the presence of a fiber bobbin is detected, behind it (opposite to the transport direction) the first blocking element is automatically switched on, ie activated into a blocking position. The vibratory conveyor conveys further fiber bobbins towards this blocking member. As soon as it is detected that fiber bobbins are also located in front of the first blocking element, the second blocking element is switched on and activated into the blocking position, so that a sufficient number of The third, fourth...
The blocking member is switched on and activated.

The removal of the fiber bobbin takes place independently of its supply. If the supply of fiber bobbins takes place more quickly than their delivery or removal, the vibrating conveyor is switched off when the individual fiber bobbin reaches a predetermined stock amount, and then the fiber bobbin located in front is delivered. It is advantageous to be able to switch back on once the switch is turned on. When one fiber bobbin is removed, the blocking member is temporarily opened to allow sequential feeding of the fiber bobbins. If this opening of the blocking elements is carried out sequentially in time, starting from the blocking element that is foremost in the transport direction, overlapping or clamping of the fiber bobbins is advantageously prevented.

In the case of certain bobbins, only two blocking elements can be used to carry out the delivery operation. In this case, the first initial blocking element is arranged at the end of the transport track behind the first fiber bobbin, and the second blocking element is arranged at a distance corresponding to the entire length of several bobbins from the first blocking element. Advantageously, it is arranged at the rear of the part. A chamber is formed in this manner between the first and second blocking member, for example for five successively located bobbins. A detector for causing a stoppage of the vibratory conveyor can then be arranged next to this chamber or in this chamber, at the rear as viewed in the conveying direction. In this case, the vibrating conveyor is
The switch is switched off only when the chamber is filled with fiber bobbins. In this configuration, it is important to prevent the pushing force of the advancing fiber bobbin from exceeding a predetermined conveying pressure.
Otherwise, the inside and outside of the bobbin or the top and bottom of the bobbin may overlap, causing them to tighten and become immovable.

The invention will now be explained with reference to the illustrated embodiment.

The drawing shows a vibratory conveyor 11 with an open top.
Groups of fiber bobbins 12 of approximately the same type are fed into the vibrating conveyor 11 from above. Vibration conveyor 1
1 vibration causes the bobbin to move along a spiral conveying track 13.
Move one piece at a time from the top along the line. At the end 14 of the transport track 13 there is a bobbin transfer device 15, which consists of a flap 17 operated by an electromagnet 16. Below the flap 17, a chute 18 extends to a bobbin conveyor 19, which has a conveyor belt 20 driven by a motor 21.

Mounted on the conveyor belt 20 at regular intervals are transport pockets 22, each of which receives one fiber bobbin. To this end, the conveyor belt 20 stops each time an empty transport pocket is reached on the underside of the chute 18, as shown in the drawing. At the other end of the bobbin conveyor, the transport pockets filled with bobbins are lowered neatly into a bobbin magazine, transport box or the like. This lowering device is not shown in the drawings.

The bobbin conveyor 19 is in operative connection with the bobbin transfer device 15. That is, each time an empty transport pocket arrives under the chute 18, the flap 17 automatically opens and the front end bobbin slides down the chute 18 into the transport pocket. By closing the flap 17 again, the conveyor belt 2
0 is caused to move in the direction of arrow 39. The conveyor belt 20 is then stopped again when another empty transport pocket is under the chute 18.

A bobbin holding device 23 is provided at the end of the conveying track 13 of the vibrating conveyor 11. It has four blocking members 24, 25, 26 and 27. Each blocking member has an angle-shaped lever 29 pivotally mounted on the bracket 28, in which a pull bar 30 of an electromagnet 31 is engaged. At the end of the longer arm of the chevron lever 29 is a flag-like member 32.

FIG. 3 shows one blocking member in the activated position (switch-on position). In this position transport of the fiber bobbin is prevented. However, when this blocking member is in the inoperative position (switch-off position), the bobbin is not prevented from being transported. This is because the flag member 32 is in position 32a.

As can be seen from FIG. 1, the blocking members are sequentially arranged on the conveying track at intervals larger than the entire length of the bobbin. A controlling bobbin detector is assigned to each blocking element, which sensor is located in front of the associated blocking element in the conveying direction. The blocking member 24 has a detector 33
However, the blocking member 25 has a detector 34, the blocking member 26 has a detector 35, and the blocking member 27
A detector 36 is assigned to each. The detector can be, for example, a photoelectric device which responds to the presence of a bobbin that is not transported and which in this case operates the associated blocking member into an activated position.

As can be seen in FIG. 1, a first detector 37 for detecting an excess of the maximum value of four bobbins that are not transported, which are located one after the other at the end of the transport track 13;
Further, as can be seen from FIG. 2, a second detector for detecting removal of the bobbin located at the front in the transport direction is provided. The detectors 37 and 38 are connected to the drive device of the vibrating conveyor.
The oscillating conveyor is operatively connected in a manner not shown, so that when the first detector 37 responds, the vibratory conveyor is switched off and when the second detector 38 responds, it is switched back on. Furthermore, the second detector 38 is operatively connected in a manner not shown to the electromagnets of all blocking members, so that upon reaction of the second detector, the blocking members automatically and simultaneously simultaneously and momentarily automatically switched off, and then the bobbin holding device is automatically transferred back into its normal functional state, in other words the switching state of the blocking element is again switched to the state in which it cooperates with the associated bobbin detector after receiving the control pulse. be returned.

As soon as the electrical circuit of the electromagnet 16 of the bobbin transfer device 15 is switched on and the flap 17 is opened, controlled by the bobbin conveyor 19, the bobbin 12 on the flap 17 is moved to the chute 18.
and slides down into the transport pocket 22a below. The opened flap 17 is connected to the second detector 3
8 and then close again. As a result, on the one hand, the vibratory conveyor is switched on again if it was previously switched off, and on the other hand, the entire blocking member is switched off for a short time and then immediately returned to its normal function. . All bobbins previously stopped by the blocking member are in this case moved again, the blocking member 24 detecting the bobbin detector 33
is closed only when it detects that a bobbin, which has been slipped onto the flap which has been closed again during this time, is present without being conveyed. When the blocking member 24 is closed, it acts as a stop for the following bobbin, so that the detector 34 can now switch on the blocking member 25 and move it into the working position. Closing of the blocking elements takes place in this manner one after the other, until finally it is detected by the first detector 37 that a bobbin has been placed in front of the blocking element 27. . The vibratory conveyor is then automatically switched off if no further bobbin has been delivered during this time. The switching of the blocking elements into the switch-off position advantageously takes place sequentially in time, starting from the blocking element located at the front in the transport direction. It is also possible to use a delay device for this purpose. In this case, the advantage is that no disturbances due to excessively rapid or irregular bobbin transport can occur. Approximately the same effect can also be achieved by increasing the spacing between the blocking members progressively in a direction opposite to the conveying direction, if sufficient space exists for such measures. In this case, after each short interruption, the switching of the blocking elements into the switch-on position takes place completely automatically and sequentially, starting with the blocking element located forward in the direction of conveyance.

The bobbin holding device 23 can also be configured such that, instead of just one bobbin, for example two or three bobbins located sequentially at the rear are prevented from being conveyed by one blocking member. be. The associated bobbin detector is in this case two or three of these
It is placed next to the last bobbin of the number of bobbins. In this case, it is possible to prevent the bobbins from being pushed against each other in a horizontally aligned manner or one above the other by appropriately configuring the shape of the conveyor track, for example by configuring the cross section of the conveyor track in a V-shape. I can do it.
