Abstract

PURPOSE:To increase the work efficiency in a press device by arranging a spare blank feeding device between a press device and destacker device. CONSTITUTION:A spare blank feeding device 14 is arranged at the side part of a blank transfer line in the adequate position between a destacker station 4 and press device 10. This spare feeding device 14 is composed by a guide column 16, chain 21, pickup device 19 and transfer device 20, etc. When two sheets overlapping state of the blank 2'' is detected by a detector 12 at the stacker station 4, the pickup device 19 holds with suction the spare blank 2' of the above of a shelf 15 first and the spare blank 2' is carried then onto the transfer line via transfer device 20 and positioned. For the while the double piled blank 2' is rejected, so the work is continued without stopping the press device 10. The work efficiency in the press is therefore increased.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to press equipment.

[Prior Art] FIG. 2 does not show an example of press equipment, in which a stack 2 consisting of blanks 2' stacked in multiple layers on a pallet 1 is transferred to a destacker station 4 by a supply conveyor 3.
It is now being transported up to At the destacker station 4, the stack 2 is suctioned one by one by a pick-up device 5, adsorbed by a magnetic belt feeder 6, and sent to the next process. The blank 2' fed out by the magnetic belt feeder 6 is cleaned by a cleaning device 7, then positioned by a positioning device [8], and supplied to a press device 10 by a loading device 9. Note that 11 is a discharge conveyor for discharging empty pallets 1.

In the press equipment, when the stack 2 is sucked by the pickup device 5, the stack 2 may be sucked in a double blank state due to adhesion of oil or the like. Therefore, conventionally, the magnetic belt feeder 6 is provided with a double blank detector 12, and when this detector 12 detects that two blanks 2' are stacked, the magnetic belt feeder 6 is reversed and sent to the reject blank station 13. The two stacked blanks 2' were to be rejected.

[Problems to be Solved by the Invention] However, in the conventional method, when a double blank is rejected, the next blank 2' will not be ready in time for the press cycle, so the press device 10 must be temporarily stopped, and the work is interrupted. It was inefficient. In addition, since the blank 2' located at the bottom of the stack 2 may have some flaws, even after being sent to the reject blank station 13, the blank 2' located at the bottom of the stack 2 may be damaged by the press machine when discharging the empty pallet 1 and supplying the next loaded pallet 1. 10 had to be stopped.

The present invention aims to eliminate such stoppage time of the press apparatus 10 and improve work efficiency.

[Means for Solving the Problems] The present invention has a configuration in which a preliminary blank supply device is provided between the destacker device and the press device.

[Effect] Therefore, when a double blank occurs, empty or loaded bar 2
When exchanging the blank, a spare blank is supplied from the spare blank supply device.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the press equipment of the present invention is installed at an appropriate position between the discoverer station 4 and the press device 10, for example, on the side of the blank conveyance line between the cleaning device @7 and the positioning device 8. , a spare blank supply device 14 is provided for feeding the spare blank 2'' onto the conveyance line. In FIG. 1, the same reference numerals as in FIG. 2 indicate the same parts.

The spare blank supply device 14 includes a guide column 16 that guides a plurality of blank shelves 15 in a vertically movable manner, a chain 21 that moves along the guide column 16 and connects eight shelves 15 at predetermined intervals, and drives the chain 21. a motor 18 equipped with a wheel 17 to pick up the spare blank 2″ on the shelf 15;
In order to supply the spare blank 2'' sucked in step 9 onto the conveyor plate between the cleaning device 7 and the positioning device 8, the pickup device M19 is moved from a position above the shelf 15 to above the conveyance line. It consists of @20.

Now, at the stacker station 4, if the detector 12 detects that the blanks 2' that have been sucked by the pickup device 5 and are about to be sucked and conveyed by the magnetic belt feeder 6 are in a two-layered state, a spare blank is supplied. The device 14 feeds the preliminary blanks 2'' onto the conveyor line.

That is, the pickup device 19 sucks and holds the spare blank 2'' placed on the blank shelf 15, and then drives the conveyance device 20 to move the preliminary blank 2'' together with the pickup device 19 onto the conveyance line. At this point, the pickup device 19 is released.

At this time, the positioning device i8 has already moved to the position (indicated by the imaginary line) for receiving the spare blank 2''.The press machine @1G continues its work without stopping.

While supplying the above 2" spare blanks, 2"
The stacked blanks 2' are transported to a jet blanking station 13.

The spare blank supply device 14 rotates the wheel 17 by driving the motor 18 and moves the chain 18 to sequentially raise the shelf 15 and position the spare blank 2'' within the operating range of the pickup device 119. Make sure to keep it.

In addition, the preliminary blank supply device is operated in the same way as described above even after the lowest blank 2' on the pallet 1 is sent to the reject blank station 13 until the next loaded pallet 1 is supplied to the destacker station 4. 1
At step 4, a spare blank 2'' is supplied.

It should be noted that the invention is not limited to the above-mentioned embodiment, and the palm-held blank supply device 14 may be positioned at such a position that it can supply the spare blank 2'' to the inlet of the cleaning device 1, or in any other suitable position. It can be provided at any location.

[Effects of the Invention] As explained above, according to the press equipment of the present invention, a spare blank can be supplied onto the conveyance line from the spare blank supply device when a double blank occurs or when an empty or loaded pallet is replaced. Therefore, there is no downtime for the press equipment, and work efficiency is improved, which is an excellent effect.
