Bunker and method of work thereof that control stores and carries empty light tank body to use

Technical field

The present invention relates to store the bunker that light-duty hollow tank body is used, above-mentioned bunker is envisioned for specially and plastic slack tank is supplied to machining production line (fill, bottled, label manufacturing line etc.) later on temporarily piles up before (comprising other goods though its use can be summarized as), above-mentioned bunker is this type, be provided with the outlet of loading inlet and discharging these tank bodies by gravitational method at its high level place in its underpart setting, it be stacked in exit conveyor above, belt conveyor is connected to relevant later processing or handles above-mentioned jar manufacturing line.The invention still further relates to the method that control stored and carried empty light tank body.

Background technology

When (for example in high-capacity bunker inside, the vertical parallel hexahedron chamber that has 5 meters of 4 meters of sides and height) bottom is provided with the unloading outlet to discharge this hollow light-duty tank body, for example during plastics system thin-walled can, highly tend to form " vault " or " bridge formation ", they hinder above-mentioned tank body regular and mobile continuously by relevant unloading outlet.This is because in fact, above-mentioned tank body often has the fitfull shape and has protrusion, as handle, neck etc., cause that (particularly under the situation of other overlapping jar disorder distribution and withstanding pressure) above-mentioned tank body stops up mutually, thereby form the structure of a kind of being called as " vault " or " bridge formation " that said structure supports and withstands bulkhead, therefore cause jam-packed in the bunker, thereby stop tank body that bunker is contained and the whole tank bodies that are positioned at the top to land to the bunker bottom by gravity.

The empty light tank body of influence in the large scale bunker, store another be limited in its lower crushing strength, for example when standing when crossing the eminence free falling to collide or a large amount of tank body when standing pressure by the weight generation when being deposited in given tank body top.Therefore, the maximum piling height of the maximum height and bottom, the bunker inherence load-bearing surface upper tank body of inlet free falling is loaded in restriction by top.

Another shortcoming of above-mentioned bunker is, if particularly these bunkers are used to store those subsequently with the tank body of filling liquid or the beverage can of consuming for people, the inside that just needs the cleaned at regular intervals bunker, above-mentioned cleaning is the work that labour intensity is big, because these chamber size are big, the difficulty (only can touch by its open top with by the use jacking system usually) that is difficult to touch is arranged in addition.

Provide several devices to solve the problem of bulk material such as the pit coal or the cobble of other solid densification of gravity transfer in existing technology, they tend to form vault.

U.S. Pat 2,905,365 and 3,286,886 disclose the funnel storage bin or the device of conveying bulk materials, and they are made up of the hopper that has the stiffener plate fixation wall, with the cross-sectional plane that rectangle is arranged, its surface region has tapering by the top end of to, and above-mentioned hopper is provided with outlet in its lower end.Stiffener plate is connected to above-mentioned at least one wall in the inboard, with provide the device of vibration to be connected to above-mentioned flat board.

The shortcoming that this layout has is to have the gap between stiffener plate and bin stock bulkhead, tends to receive and the container cavity particle, hinders the work of device, be under the situation of decomposer not removing they make cleaning very difficult.On the other hand, the mechanism that transmitting vibrations is used is arranged on the outside of storage bin, and they must pass the relevant fixation wall of storage bin so that be connected with portable plate, so just cause the relative complexity of said mechanism.
