Description

The ring type metal sheet memory device that has towed pitch of the laps

Technical field

The present invention relates to a kind of ring type metal sheet memory device that has towed pitch of the laps.

Background technology

Pipeline of producing on tinuous production and/or welding section field are carried out constant presenting as the metal sheet memory device permission of holder to the manufacturing line that is positioned at the memory device downstream, and this knows in this area and be commonly used.

Memory device places between the spool and manufacturing line of at least one carrying roll film usually, the metal sheet that stored number is enough, permission is replaced the hole spool with the spool that carries a volume metal sheet, and with the metal sheet of new roll film with on empty reel spool around under metal sheet " afterbody " combine, and do not need to stop manufacturing line.

Known in the artly there is polytype metal sheet memory device, merely as example, can exemplify: slot type memory device (free ring) and have the toroidal memory (being called floops) of push-press type pitch of the laps, the great drawback that they exist is, if metal sheet (too) is thin and/or with ductility (very large) when material is made, can not normal running.

The ring type metal sheet memory device that has towed pitch of the laps can overcome aforementioned disadvantages.System by mode of traction storage metal sheet (such as, for example, drawbench), be known in this area, but the applicant does not learn the memory device that metal sheet is stored as ring by mode of traction.

Summary of the invention

The specific embodiment

In the accompanying drawings, corresponding element refers to identical Reference numeral.

Fig. 1 schematically shows the front elevation of metal sheet memory device 1 produced according to the invention, this metal sheet memory device is carried by metal construction 100, and comprises the inlet cohort 2 of at least one suitable guide wire plate 20, pinch roll 3, the mobile roller (dandy roll) 4 of metal sheet 20 tension force that control is come, a series of loose rolls 5, the outside mobile rotating disk 6 of carrying servo-actuated nip rolls 12, the internal fixation rotating disk 7 (coaxial) of carrying servo-actuated transfer roller 13 with rotating disk 6, leave the mobile roller (pinch roll) 18 of metal sheet 20 tension force of memory device 1 with fixing 7 one-tenth single-piece spiral paths 15 of rotating disk (more clear in Fig. 2) and control.

Do not describe in inlet cohort 2, pinch roll 3, mobile roller (4,18), loose roll (5,12,13) and spiral path 15 literary compositions, because they are known for those skilled in the art.

Two a plurality of rollers 8 of rotating

disk

6,7 carryings, roller 8 is fit to the towed metal sheet ring that is wound on the described roller 8 of carrying, described roller 8 is installed in the swing arm 9, swing arm 9 is connected to each other by brace rod 10, and be subjected to piston (or other known hydraulic devices, driving Fig. 3), the operation of swing arm is managed by logical block, and logical block is preferably also controlled pinch roll 3 and outside rotating disk 6.

For content shown in the reduced graph, logical block and sensor thereof and actuator omit in the accompanying drawings, in addition, only express in Fig. 1 that a metal sheet ring is positioned at mobile rotating disk 6 and fixedly on the rotating disk 7.

In working order (Fig. 1), metal sheet 20 is through inlet cohort 2, pinch roll 3, mobile roller 4 and loose roll 5, arrive the nip rolls 12 of mobile rotating disk 6, these nip rolls are with rotating disk 6 rotations, the metal sheet 20 that enters is turned to the metal sheet ring that is positioned on the mobile rotating disk 6, meanwhile, turn to the metal sheet ring that is positioned on the fixing rotating disk 7, contact with the roller 8 of mobile rotating disk 6 from the metal sheet 20 of metal sheet ring.

, before arriving manufacturing line, from mobile roller 8 below, pass through from the metal sheet 20 of fixedly rotating disk 7 and spiral path 15.

Fig. 2 schematically shows the lateral plan of metal sheet memory device 1 shown in Figure 1, for content shown in the reduced graph, in Fig. 2, only show metal construction 10, mobile rotating disk 6, spiral path 15, one of them roller 8, wherein swing arm 9 and brace rod 10 wherein with each Reference numeral.

Fig. 3 schematically shows the back view of metal sheet memory device 1 shown in Figure 1, can see the rear portion of the mobile rotating disk 6 of metal construction 100, inlet cohort 2, pinch roll 3, the device 41 of controlling mobile roller 4, bearing hydraulic cylinder body 11 among Fig. 3, and the fixing rear portion of rotating disk 7, wherein hydraulic cylinder 11 acts on the pin of swing arm 9.

In embodiment shown in Figure 3, each hydraulic cylinder 11 acts on the wherein pin of a swing arm 9, and the pin of a described wherein swing arm 9 is couple to the pin of adjacent swing arm 9 by brace rod 10 machineries.

Fig. 4 schematically shows the metal sheet memory device shown in Figure 1 that is in idle condition: metal sheet 20 is only through inlet cohort 2, enter pinch roll 3, be positioned on the mobile roller 4, be positioned on the loose roll 5, be positioned on the servo-actuated transfer roller 13, be positioned on the spiral path 15 and be positioned on the mobile roller 18 (tension force of the metal sheet 20 of memory device 1 is left in control), and do not relate to two rotating

disks

6,7.

Fig. 5 and 6 schematically shows metal sheet memory device shown in Figure 1 in two consecutive steps, metal sheet 20 is wound on mobile rotating disk and fixedly on the rotating

disk

6,7.

Equal the idle condition (Fig. 4) of output speed from the input speed of metal sheet 20, mobile rotating disk 6 beginnings cause the output speed of the speed of metal sheet 20 input stores 1 greater than the guiding manufacturing line along anticlockwise motion (in the described in the text embodiment).With the transfer roller 13 traction metal sheets 20 of 6 one-tenth single-piece nip rolls 12 of rotating disk against fixing rotating disk 7 (Fig. 5), then it is drawn to by on the roller 8 of mobile rotating disk 6 and fixedly rotating disk 7 carryings (Fig. 6), and continue with this speed rotation, till the ring of predetermined quantity is formed on two rotating

disks

6,7.

Should remember that the speed of metal sheet 20 that enters memory device 1 is relevant with the rotative speed of pinch roll 3, and on two rotating

disks

6,7, form in the process of ring that metal sheet 20 leaves memory device 1 to present required speed to manufacturing line.

When having formed the ring of requirement on two rotating

disks

6,7, mobile rotating disk 6 and pinch roll 3 reduces their rotative speeds, so that when mobile rotating disk stops, the amount that enters the metal sheet 20 of memory device 1 equals the amount of the metal sheet that leaves towards manufacturing line.

In case reach this situation, pinch roll 3 speed that slows down gradually, up to stopping (stopping the metal sheet 20 of arrival), and 6 beginnings of mobile rotating disk are along rotating in the opposite direction with previous side, discharge the metal sheet 20 that is formed on the ring on rotating

disk

6 and 7 and will be stored in the memory device 1 and present to manufacturing line.

Pinch roll 3 stops metal sheet 20 these situations of arrival, allows the remetal source, another kind of roll film is attached to the end of the metal sheet 20 of arrival.

When no longer storing metal sheet 20 on the memory device 1, the mobile rotating disk speed that slows down gradually, up to stopping, if recover the inlet that metal sheet 20 flows into mobile rotating disk, then this memory device switches (perhaps can switch) to idle condition (Fig. 4), then, again with metal sheet 20 coilings (perhaps can coiling) on two rotating disks 6 and 7 (Fig. 5 and 6).

The operation of traction memory device 1 of the present invention illustrates no longer in more detail, because be obvious to those skilled in the art, perhaps under any circumstance, can both be derived by the operation of push-press type memory device known in the art.

In the case without departing from the scope of the present invention, those skilled in the art can carry out the common knowledge in this area and/or change and improvement that natural evolution enlightened to the aforementioned metal board memory.
