The container that has bulge loop is hung the device of conveying

Affiliated field

The present invention relates to a kind of feedway, it is carried by the bulge loop of Suspended containers.

Background technology

Be extensive use of pneumatic conveyor, the plastics and the non-plastic container that are used for neck is had bulge loop are carried, and general bottle is made by PVC, and it need adopt the bearing guide that is used to support bulge loop.Then, bottle is by a series of fans drive, and 5 to 7 meters of these fan spaces also produce air-flow along throughput direction.

The shortcoming of this system is that fan makes a large amount of air movements tend to cause the pollution of container.

Another shortcoming is that noise is big, high engine installation of frame and energy consumption height.

Gondola patent of invention NO.1190535 discloses a kind of mechanical device from plastic bottle to forward mounting that carry, it is provided with load-transfer device on whole travel line, the bottle grasping mechanism is housed on the load-transfer device, is held on the bulge loop below of bottleneck, hang bottle and carry by guide groove along travel line.

Above-mentioned patent does not also obtain practical application, and this is because said apparatus the turning of delivery system and up section, runs into many difficult problems.

In fact, above-mentioned delivery system is a kind of motor-driven element of imagination, and the belt that is generally belt or combines with other element (as rubber coated band) allows the bulge loop mutual action of they and container.Described bulge loop and motor-driven element disalignment or depart from motor-driven element make that bulge loop has different curvature with motor-driven element in the turnaround section of carrying.Clearly, can produce many operational problems aspect this installation, tensioning and the size calculating at conveyer.

Gondola patent application NO.40029A/90 discloses the conveyer of another kind of employing pushing mechanism, it is conceived to the initiatively motion of branch of osed top chain, the plastics pushing member that extends laterally is installed on the chain, this element acts on container one side, and chain is fixed on a pair of longitudinally guiding element.

Because the shutdown in conveyer downstream can cause the accumulation of container, this can produce big noise, and also can be caused the breakage of pushing member and container in the sliding force of container by the pushing member continuous action.

Goal of the invention

The objective of the invention is in order to solve an above-mentioned difficult problem, be particularly useful for the container of band bulge loop is hung conveying, and can carry continuously the turnaround section of travel line and up section, can replace effectively with the delivery system of air as propulsive effort, and the complexity that cuts down the consumption of energy significantly and install, and stop Shi Buhui in transfer movement and produce the problem that container is piled up.

Described purpose can reach by feedway of the present invention fully; the feature of device is referring to following specification sheets; be defined by the claims; particularly the track that forms of the side of container pushing member basically with this device in the track identical (promptly having identical curvature) of motor-driven element; described motor-driven element dynamically is connected with pushing member, and both are positioned on the different planes.

Two preferred embodiments by following specification sheets can more clearly understand feature of the present invention, but they are also not exclusively as the embodiment that the present invention is limited, below, describe by accompanying drawing:

Brief description

Fig. 1 and Fig. 2 show the device of two different embodiment, along the axis of movement part sectional view;

Fig. 3 shows the lateral plan of the device that is substantially perpendicular to Fig. 1 direction;

Fig. 4 is the birds-eye view along the device of the A-A line partly cut-away of Fig. 3;

Fig. 5 is the birds-eye view of feedway in turnaround section.

Embodiment

Referring to Fig. 1, label 1 is specifically represented the traction framework or the guide plate of chain-linked conveyer, this chain-linked conveyer is made of pair of rolls pillar endless chain, this chain is plane motion less than 20 degree angles along substantial horizontal or with sense of motion, in the ascent stage of carrying or descent stage with respect to throughput direction even bigger inclination can be arranged.

By suitable element 10,, opposite guide plate 4 is fixed on the guide plate 1 moving conduit that is used for support chains and between guide plate and opposite guide plate, forms chain as screw.

Roller formula chain

2a and 2b move along direction shown in the arrow 8, and actuator for example, can come chain drive-belt by the flat sprocket wheel that is fixed in the rotating shaft of embedding because of being that known forms does not illustrate, and chain roll is on sprocket wheel.

Below the roller 3 of first moving element " C " shape support 7 is installed, this supports 7 and forms second moving element, and it stretches out than end portion 7a, is used to support the edge of each container 5 bulge loop, the axis in-line of the center link of this end 7a and described roller.In fact, support 7 and be connected on the roller 3 of chain, the movable end 7a that its shape should be used in supporting container roughly forms the planar section of corresponding pair of rolls mast axis.Each supports 7 and links to each other with a pair of roller of chain.Be provided with by this form and support 7, the tracks with corresponding chain is consistent basically to make delivery track as the movable end 7a formation of supporting and structure for conveying, and they have identical curvature.

Adopt this mode, for adopting conventional apparatus can eliminate at all problems that the travel line turnaround section produces, this is because in turnaround section, and the path of motion of path of motion that is formed by first moving element (being chain) and lower end 7a is in full accord.In order to obtain this result, shown in the label 9 of Fig. 1, the plane of movement of container (by the determined plane of corresponding bulge loop) moves down, and is positioned at the below on chain movement plane.

The ad hoc structure of guide plate 1 and opposite guide plate 4 has significantly increased the rigidity of structure of device, has avoided supporting 7 unfavorable distortion, in addition, makes device suitable with the container with different size bottleneck and bulge loop easily.Easily imagination the 1a inside, interval of a plurality of blocks or pad insertion guide plate, can be dwindled the width of central aisle 11, and opposite guide plate 4 is provided with another and organizes corresponding pad and can dwindle its lateral dimensions.

In another embodiment shown in Figure 2, opposite guide plate 4 is not set, the supporting member 12 be connected on the roller is installed on the chain, chain is in the interior groove milling campaign of the guide plate 1 that is used for supporting it.

Do not have embodiment shown here according to another, it is contemplated that,, can only adopt yet a chain 2 of movable support is housed, fixing supporting guide is set at the opposite side of bulge loop corresponding to the terms of settlement that Fig. 1 and Fig. 2 proposed.

Referring to Fig. 4, label 71 parts of end 7a are isosceles trapezoid basically especially, and their interconnective parts 72 are rounded off basically.

The shape of the end of each supporting member 7 or annex 7a forms an area supported, be used at the outstanding bulge loop of the two-side supporting of container, and can keep the continuity of this area supported in turnaround section, this is local overlapping assurance of cavetto part of the isosceles trapezoid of the supporting member that linked to each other by front and back.

The central orbit that the longer sides of isosceles trapezoid 71 moves through in the face of container 5.

Clearly; chain-linked conveyer 2 can be replaced by the conveyer of other form; for example by the traction of belt or hawser, above the conveyer of support is housed; in turnaround section; as long as the path of motion basically identical of the formed path of motion of movable supporting base end portion of assurance holding vessels and original traction element (as belt or hawser) makes them have identical curvature.

Term " basically identical " is that the path of motion of finger ends 7a is coaxial with the conveying track, or has identical curvature, and the side direction play is at least less than 20 millimeters.
