SE447571B - Hardware for managing spools - Google Patents

Abstract

Peripheral hardware for a machine (1) for the production of spools (3) for cash registers, calculators, data tapes, and the like. The equipment's main components include a holder (4) connected to the production machine (1), a separator (5) to afterwards receive the spool (2) coming from the holder and to press the spools out of their set in succession, a divider (6) to detect spools (3) that do not allow themselves to be separated, and a calibre press (7) to calibrate the separated spools (3) to the right width. The equipment also entails a stamping device (8) to stamp the spools (3) on either end and a transporter (9) for transporting the spools to a shrink wrap machine (10) to pack a predetermined number of spools in shrink wrap. After the shrink wrap machine there is another transporter (11) for transport of the shrink wrapped spools (3) to a packing machine (12) for packing of these into cartons (36).<IMAGE>

Description

447 571 10 15 20 25 30 35 2 2 of the rollers to a shrink film plant for packing a predetermined number of rolls in shrink film, an additional transport device being provided for transporting the shrink film-packed rolls to a packing station for packing these rolls in cartons.

The invention is described in more detail below with reference to the accompanying drawings, which show a preferred embodiment. Fig. 1 shows in horizontal projection a machine arrangement, in which the equipment according to the invention is included. Fig. 2 shows a section along the line A-A in Fig. 1. Fig. 3 also shows a section, but along the line B-B in Fig. 1. Fig. 4 shows schematically and in perspective, seen from the front, parts of a disassembly machine included in the equipment. Figures 5 and 6 show a part of the disassembly machine according to Figure 4 from the front and from the side, respectively. Figs. 7-9 show from the side, from the front and from above a separating device included in the equipment according to the invention. Fig. 10 shows from behind a calibrating press included in the equipment.

As can be seen from Fig. 1, the patent-pending equipment is part of a machine assembly with several machines 1, of which only two are visible, for the manufacture of roller sets 2. Of these roller sets are manufactured by means of the equipment according to the invention rollers 3, which for the most part forms receipt rolls for cash registers.

This equipment mainly comprises a waiting bearing 4 in connection with the manufacturing machine 1, a disassembly machine 5, a separating device 6, a calibration press 7, a stamping device 8, a conveyor 9, a shrink film plant 10, a conveyor 11 and a packing plant. 12.

The manufacturing machines 1 are of a type well known in the context and will therefore not be described in detail. The only thing that needs to be said about them is that they cut off a roll in several, say 20, webs which are wound up on sleeves which are threaded on a spindle rotatably driven in the machine and easily removable from the machine; When this spindle is full, it is transferred to the waiting bearing 4, where the operator removes the spindle.

There are a number of roller sets 2 left in the waiting warehouse, which are gradually transferred to the disassembly machine 5.

The disassembly machine 5 has an feed channel 13, which is limited by a bottom slide rail 14 with a central, longitudinal slot 15 and by two side support plates 16. Furthermore, the machine 5 has a discharge channel 17, which is limited by a bottom plate 18 and two side guide plates 19. Between and the discharge channels 13, 17 there is a later described club 20 for disassembling the rollers 3 from the roller set 2.

A pusher arm 21 extends through the slot 15 in the bottom slide rail 14 and is connected at its lower end, located below the rail 14, to a cylinder unit 22, suitably an Origacylinder. At its upper end, the pusher arm 21 carries a feed lug 23, which abuts against the end of the roller set 2 and feeds this to the club 20.

The side support plates 16 and the side guide plates 19 are adjustable by means of suitable devices, not described in more detail, for relatively sluggish advancement of the roller set 2 to the club and relatively easy discharge of the disassembled rollers 3 from the club 20.

The club 20 has two arms 26 adjustably mounted on the upper end of a pendulum 25 mounted in a steel bearing 24, which are covered with suitable, elastic profiles 27 of rubber, plastic or the like. The arms 26 are set according to the current roll diameter plus a small clearance of the order of 1.5-2, Ö mm. The lower end of the pendulum 25 is actuated by an eccentric 28, which is mounted on the output shaft of an electric motor 29, so that the arms 26 are subjected to a rapid oscillating movement transversely to the longitudinal direction of the input and output channels 13, 17 and thereby provide the desired disassembly of the rollers 3 from the roller set 2.

After the disassembling machine 5 comes the separating device 6, see Figs. 7-9, which has a belt conveyor 30 as an extension of the discharge channel 17 of the disassembling machine 5. Disassembled rollers 3 are blown by means of an air nozzle 31 into a channel 32, which is only slightly wider than the roll width and which is slightly inclined, so that the rollers are transferred to the roller track 9 and fed to the calibrating press 7. The rollers 3 which cannot be disassembled in the disassembly machine 5 (discarded rollers) are too "wide" to be able to enter the channel 32 and are instead deflected by a spring-loaded plate 33 and transported further by means of the conveyor 30 to a waste container or the like.

The calibrating press 7 placed after the separating device 6 operates continuously and is very easy to change to its stroke length. The press has a press cylinder 34 and is equipped with a time relay, which means that it does not stop if it should be overloaded during the first work stroke. By striking several times against the passing rollers' 3, which are fed by the press of the conveyor belt 9, these are calibrated to the correct width.

The stamping device 8 is placed after the calibrating press 7 and has easily replaceable text jackets and dyeing.

The device has double roller stamps and side conveyor belts for any printed side. The side conveyor belts mean that the rollers 3 are fixed in position at the stamping, whereby a very good finish on the print is obtained.

The conveyor 9 between the stamping device 8 and the shrink film system 10 has photocell monitoring. It may have preselection automatic for transporting one or more rollers 3 'in width to the shrink film plant.

The shrink film plant 10 is complete with automation and shrink tunnel 35; the facility is of known design and does not need to be presented further.

From the plant 10 leads a further conveyor 11, which together with one or more similar conveyors from the other equipment extends to the packing plant 12.

In this packing plant 12, the shrink film-packed rolls 3 are packed in cartons 36 for delivery to the customers. E The equipment also includes a complete control system for the various components, such as reset function, small / large rollers, emergency maneuver, restart after emergency maneuver and emergency stop. The conveyors, which are designed as conveyor belts, are partly thyristor controlled for any transport speed and are tachometer monitored for speed synchronization.

The invention must of course not be considered limited to the illustrated and described embodiment, but can be modified in several ways within the scope of the protection claimed in the appended claims.
