Abstract

The device transfers reels from a stack to a processing machine, using a reel carrier. The carrier (1) has grab jaws (13,26), adjustable at right angles to the core axis of a reel, and suction grabs (23), which engage on intermediate reel layers. The grab jaws are formed as clamping bars (14), pressed radially against the inner surface of a core sleeve of a reel.

Description

The invention relates to a device for handling wound material webs, in particular wrapping material for tobacco processing products Industry made bobbins, by taking down the bobbins from one using formed by spacers bobbin stack and transfer of bobbins to a processing unit associated Bobinenaufnahme means one about essentially 90 ° pivotable while the core axis of the reel from the vertical to the horizontal position aligning Bobinenträgers with transverse to the core axis of the bobbin adjustable jaws.

Hüllmaterialbobinen exist in the inventive sense of paper for wrapping a cigarette rod or filter strand, as well as packaging material, such as paper, cardboard, Stanniol or film for tobacco products, especially cigarettes or filter cigarettes.

The use of reel handling devices of the type described above Art has in a disclosed example in DE-PS 40 41 865 configuration proven in the process together cooperating components, in the lying flat or with vertically aligned core axis at a storage station or bobbins stacked on a pallet horizontally to a machine side aligned Bobinenaufnahmezapfen to be transferred by the required Reorientation of the bobbins by appropriate rotary actuators as well long-range transfer movements by appropriate multi-axis linear drives is realized.

According to EP 0 744 363 A2, it is known that in the depalletization of layers stacked and separated by intermediate layers of pack blanks, to remove such intermediate layers by a special suction pad assembly.

From DE 195 38 392 A1 a device for handling coils is known, which with a gripper for coils and a gripper for between the Coils arranged liners is equipped, the grippers alternately can be used.

Furthermore, from DE 43 41 925 A1 a handling device for coils and sleeves known with a gripper, which in the axial direction of the coils or sleeves slidable plate through which the coils or sleeves of the gripper can be deported.

The invention is based on the object, a handling device of the above to improve their type and in particular to increase their efficiency.

This object is achieved in that the Bobinenträger with one parallel to the core axis the bobbin extendable pusher plate as well as with the intermediate position Suction pads is fitted and that the suction pads on the outer surface the extendable thrust plate are arranged.

An independent of the respective bobbin diameter usable, relatively small The arrangement according to a further development is that the jaw grippers as radially engageable against the inner surface of a core sleeve of the bobbin Clamping webs are formed, expediently according to another proposal three provided at angles of 120 ° to each other clamping webs are. In this way, the bobbin pivoted by 90 ° can be relatively easily relative center to the Bobinenaufnahme.

On the one hand to keep the bobbins safe during the transfer and on the other hand to allow a safe, exact threading on the Bobinenaufnahme is after an additional proposal which extendable parallel to the core axis of the reel Pusher plate relative to the inner clamping webs substantially over the Intervention length in the core sleeve extendable. In this way, the bobbin can be used without activating the long-range movements exporting linear drives directly by a drive on Bobinenträger on the Bobbins recording be pushed.

The multiple function of the bobbin carrier is in accordance with the invention solved in a particularly simple manner such that the suction pads on the outer surface the extendable thrust plate are arranged. That way you can The suction pads without interference from the inner jaws in the extended Position the push plate on the intermediate layer.

The multifunction of the Bobinenträgers is after an additional design widened by the fact that as an additional transverse to the axis of the bobbin engagable Back gripper arranged on the extendable thrust plate, diametrically opposed provided the outer surface of the Bobine core sleeve pressable jaws are. In this way, the outer jaws when extended Push plate unhindered by the other functions, the core sleeve on the outer circumference grab and remove from the reel seat.

The advantage achieved by the invention is that by the summary or concentration of several functions better space utilization or a compressed spatial accommodation of the handling organs is achieved.

The invention will now be described with reference to an embodiment shown in the drawing explained in more detail.

The bobbin carrier 1 shown in FIGS. 1 to 3 is known from FIG Way by means of longitudinal guides 2, transverse guides 3 and vertical guides. 4 on a portal 6 relative to a standing on a pallet 7 Bobinenstapel 8 and one of a processing device not shown assigned Reel seat arranged in the form of a bearing pin 9 movable.

The Bobinenträger 1 is rotatably supported by a geared motor 11 on an axis 12 by 90 ° and equipped with a first jaw gripper 13, which has three at an angle of 120 ° to each other arranged clamping webs 14. The clamping webs 14 are with respect to a core sleeve 16 of a reel 17 radially outwardly against the inner wall of the core sleeve 16 by means of a pneumatic clamping cylinder assembly 18 spreadable.
The Bobinenträger 1 is also provided with a U-shaped thrust plate 19 which is displaceable by means of a pneumatic actuating cylinder 21 and guide rods 22 in the longitudinal direction and relative to the clamping webs 14. On the pusher plate 19 four suction pads 23 are arranged, to which via a pneumatic connection 24 suction air can be applied.
On the thrust plate 19, a second jaw gripper 26 is additionally attached, which has two diametrically engageable against the outer surface of the Bobinenkernhülse 16 by means of pneumatic adjusting cylinder 27 jaws 28.

The operation of the bobbin carrier 1 in the transfer of a reel 17 from the reel stack 8 to the bearing pin 9 of the reel seat according to the figures 4 to 6 is as follows:
The Bobinenträger 1 sets with retracted thrust plate 19 on the front side on a reel 17, so that the clamping webs 14 of the jaw gripper 13 dip into the upper part of the core sleeve 16. By activating the clamping cylinder assembly 18, the clamping webs 14 are spread against the inner wall of the core sleeve 16.

Then the Bobinenträger 1 with the Bobine 17 by activating Linear actuators on the vertical guide 4 lifted from the stack of bobbins, the bearing pin 9 the Bobinenaufnahme process and thereby by activating the geared motor 11 rotated by 90 °, so that the core axis 29 of the bobbin 17 is horizontal with the axis of the bearing pin 9 is aligned and the bobbin 17 partly on the Journal 9 can be pushed (Figure 5). To the bobbin 17 completely on the To transfer bearing pin 9 is by activation of the actuating cylinder 21 the Push plate 19 so far advanced that they the core sleeve 16 of the previously radial moved inwardly and thus detached from the inner wall of the core sleeve 16 Clamping webs 14 pushed off and transported to the same extent on the bearing pin 9 (Figure 6).

The operation of the Bobinenträgers 1 when removing an empty core sleeve 16th from the journal 9 of the reel seat according to FIGS. 7 and 8 is as follows:

The Bobinenträger 1 moves with extended thrust plate 19 in the angled 90 ° Rotary position concentric to the core axis 29 with the open jaws 28 of its jaw gripper 26 over the seated on the journal 9 Core sleeve 16. By activating the actuator cylinder 27, the jaws set 28 against the outer peripheral surface of the core sleeve 16, whereupon the Bobinenträger 1 moved back by activation of the linear guide associated linear drive is while the core sleeve 16 deducted from the bearing pin 9.

The operation of the bobbin carrier 1 in the removal of an intermediate layer 31 from the reel stack 8 according to the figures 9 and 10 is as follows:
Before a new bobbin 17 can be transferred from the bobbin stack 8 to the bearing pin 9, first a two bobbin layers 32 separating liner 31 must be removed. For this purpose, the Bobinenträger 1 sets with extended thrust plate 1 with its suction pads 23 on the intermediate layer 31, which is detected by applying suction and lifted off according to Figure 9 by activation of the vertical guide 4 associated linear drive from the Bobinenstapel 8. The Bobinenträger 1 is moved by 90 ° while rotating and disposed of the liner 31 by venting the suction pads 23 in a receptacle 33.
