Definitions
- the invention relates to a feed mechanism for feeding a material to be processed into a working assembly included in a sheet processing line, said feed mechanism comprising equipment for handling both single sheets and a strip unloaded from a reel, and which equipment optionally provides a guidance either for the single sheets or the strip onto an entry track to the working assembly.
- the material to be processed is fed to a working assembly present in the sheet processing line either in the form of single sheets or a strip to be unloaded from a reel.
- Switching over from strip material to single sheet material or reversely from single sheet material to strip material is not generally possible, or at least it is highly inconvenient.
- Production of large series from a strip material is advantageous, fast, and efficient.
- Fig. 1 shows a feed mechanism of the invention in a schematic plan view.
- Fig. 2 shows a section along a line T -II in fig. 1.
- Fig. 3 shows a section along a line ⁇ i-IH in fig. 1.
- Fig.4 shows a side view at an arrow IV in fig. 1.
- Fig. 5 shows a section along a line V-V in fig.4.
- Fig. 1 shows in a schematic plan view a portion of a sheet processing line, including a working assembly indicated by reference numeral 3.
- the working assembly 3 has its tools preferably adapted to travel crosswise relative to the lengthwise direction of the sheet processing line. In principle, however, the working assembly 3 can be any type of assembly adaptable to sheet working.
- the sheet processing line has its entry track, designated with reference numeral 6, supplied either with a strip 1 unloaded from a reel (not shown) by means of schematically illustrated equipment generally designated with reference numeral 5 or optionally with single sheets 2 by means of equipment generally designated with reference numeral 4, said equipment 4 picking up one single sheet 2 at a time from an appropriate stack onto the processing line entry track 6.
- the subsequently processed strip 1 or single sheets 2 travel from left to right in fig. 1, the section of the working assembly to the left of the working assembly 3 being hereinafter referred to as an entry side 7 and the section to the right thereof as an exit side 8.
- the working assembly 3 On its entry side 7, the working assembly 3 has the entry track 6 provided on either side thereof with at least one web guide 14 for guiding sides 15, 16 of the single sheet 2 or the strip 1 which are parallel to the entry track 6.
- the entry track 6 is provided on either side thereof with two web guides 14.
- At least one of the web guides 14 is equipped with a positioning element 17 (fig. 3) for shifting the single sheet 2 or the strip 1 to a desired position in a direction crosswise to the entry track's 6 lengthwise direction.
- the web guides 14 on the other side can be stationary, yet preferably arranged according to fig. 3 in such a way that the web guides 14 present on the opposite sides 15, 16 are adapted to center or align the single sheet 2 or the strip 1 relative to a longitudinal center hne 23 of the entry track 6. In the example of fig. 3, this is implemented by means of ball screws making up the positioning element 17.
- the working assembly 3 On its exit side 8 as well, the working assembly 3 has the entry track 6 provided on either side thereof with at least one web guide 22.
- the web guide 22 is preferably as shown in fig. 3 and thus identical to the web guide 14 mounted on the entry side 7 of the working assembly 3.
- the working assembly 3 has its entry side 7 provided with a first feeder 9 shuttling co-directionally with the entry track 6 and mounted above the entry track 6.
- the feeder 9 is equipped with grippers 25 (fig. 2), which take hold of the opposite sides 15, 16 of the single sheet 2 or the strip 1 and which are adapted to move a positioning element 10, a ball nut screw in the example of fig. 2, for shifting the single sheet 2 or the strip 1 to a desired position in a direction crosswise to the direction of the entry track 6.
- the feeder 9 has its positioning element 10 adapted to center or align the single sheet 2 or the strip 1 relative to the longitudinal center line 23 of the entry track 6.
- the entry track 6 is provided, preferably on the entry side 7 of the working assembly 3, with a barrier 11 which most preferably comprises a vertically movable rod or bar.
- the working assembly 3 has its entry side 7 provided with a separate feeding means 12 for bringing the leading edge 13 of the single sheet 2 or the strip 1 against said barrier 11.
- the feeding means 12 includes a flexible element 24 for urging said leading edge 13 tightly against the barrier 11.
- the flexible element comprises preferably a suction pad 24, a magnet or the like engagement element, functioning as a gripper element of the feeding means 12.
- the feeding means 12 is preferably adapted to operate underneath the single sheet 2 or the strip 1.
- the separate feeding means 12 is needed particularly for setting the single sheets 2 picked up from a stack precisely at a correct location on the entry track 6.
- the working assembly 3 has its entry side provided with an arrest cylinder 18 for immobilizing the subsequently processed single sheet 2 or strip 1 relative to the entry track 6, especially when the first feeder 9 performs a return motion to its start position.
- the arrest cylinder 18 is preferably integrated with the web guide 14 (fig. 3).
- the working assembly has its exit side 8 provided with a second feeder 19 adapted to shuttle parallel to the entry track 6.
- the feeder 19 is equipped with a gripper 21 , which takes hold of the leading or side edge 13, 15, 16 of the single sheet 2 or the strip 1 or a piece 20 to be removed from the single sheet 2 or the strip 1.
- the number of grippers 21 is two.
- the gripper or grippers 21 is/are adapted to travel in a direction crosswise to the direction of the entry track 6.
- the gripper/grippers is/are further adapted to travel in a vertical direction.
- the grippers 21 are adapted to perform vertical motions thereof independently of each other.
- the working assembly 3 has its exit side 8 provided with the arrest cylinder 18 for immobilizing the processed single sheet 2 or strip 1 relative to the entry track 6.
- the arrest cylinder 18 is most preferably included in the web guide 22.
- the working assembly 3 has its exit side 8 provided with a first conveyor 26, extending parallel to the entry track's 6 plane, and with a second conveyor 27 therebelow. Further provided is an adjustable guide element 28, which in the example of fig. 4 comprises an adjustable baffle, for guiding the pieces 20 removed from the strip 1 or the single sheet 2 onto the desired conveyor 26, 27.
- the feed mechanism operates as follows.
- the entry track is supplied with a strip 1 by means of conventional equipment 5 or optionally with a single sheet 2 by means of conventional equipment 4.
- the strip 1 or the single sheet 2 is set in a desired position in a direction crosswise to the entry track 6 by means of web guides 14 present on the entry side 7 of a working assembly 3. This is followed by bringing a leading edge 13 of the strip 1 or the single sheet 2 against a barrier 11, most preferably by the action of a feeding means 12 operating underneath the entry track 6 and equipped for example with suction pads 24.
- the strip 1 or the single sheet 2 has its leading edge 13 bearing tightly against the barrier 11, the strip
- a second feeder 19 mounted on the working assembly's 3 exit side 8 takes hold of the strip 1 or the web 2 and pulls a trailing end of the strip 1 or the web 2 out of the working assembly 3.
