Description

TECHNICAL FIELD

[0001] The present application relates to the field of elevator technology, more particularly, to a scissor lifting taking and placing device. BACKGROUND

[0002] Currently, the stacker is used for the flow of filter rod trays in the high-bay warehouse, which can meet the automatic warehousing, filter rod solidification, freezing, inspection, automatic delivery, manual sampling, manual return, and other operations of multiple brands of filter rods. The filter rod high-bay warehouse and the stacker play an important role in ensuring filter rod production and launching. Once the stacker fails, the entire production and launching will be severely affected. From the current use of the stacker, there is a major failure about every three months. Referring to Figure 1 , the existing technical solution is to start the emergency manual flow program outside the warehouse when the stacker fails. The specific process includes three important links. First, after the forming machine produces, the filter rod tray is manually lifted out, then stacked, and then transported to the launching machine by a manual forklift according to the production brand, and then manually added to the launching machine chain channel by the launching machine operator. Second, after the launching machine launches the filter rod, the filter rod tray is manually taken out, then stacked, and then transported to the forming machine by a manual forklift, and then manually added to the tray loader by the forming machine operator. Third, ensure the continuous operation of the original production work, and at the same time, organize technical personnel in the lane to repair the stacker, and then continue to use it after the normal operation is restored.

[0003] Currently, four stackers are connected in series in the same safety interlocking system, that is, when a manual enters the lane to repair one stacker, the remaining three stackers will also be in an emergency stop state. Therefore, the single stacker failure repair work is generally carried out during the weekend and Monday maintenance period, and cannot be repaired in a timely manner. In the emergency plan, small brand filter rods are most easily affected. If the stacker fails for more than 40 minutes, the small brand filter rod will be directly pulled to the launching machine for launching after the forming machine produces, and lacks solidification time. In addition, the emergency plan has maximized the mobilization of labor resources through process optimization, but there are still the following problems that cannot be avoided: (1) all personnel are busy with emergency disposal, the scene is very chaotic, and there is a large safety risk. (2) There is a high risk of quality risk of filter rod manual flow with wrong brand and serial number. (3) Filter rod production and use at the same time cannot guarantee the solidification time, which brings quality risks to cigarettes. (4) The whole team keeps a high working intensity, which is easy to ignore the product quality bottom line. (5) Small brand filter rods are most likely to be interrupted, affecting the production of the next process. (6) If the weekend only produces filter rod launching, due to insufficient personnel, the stacker failure will not be able to maintain the filter rod launching, causing a large number of machine stops in the cigarette packaging workshop.

[0004] Therefore, how to provide a stable and reliable emergency scissor lifting taking and placing device has become a technical problem that needs to be solved in the field. SUMMARY
