Description

  The present invention is a suspended transport system that can transport a transported object (for example, a plastic bottle, a preform, a syringe, a liquid food container, a drip container, etc.) having a locking flange on the top. In particular, the present invention relates to a suspended conveyance system that is devised so as to reliably prevent the object to be conveyed during accumulation (during residence) from being greatly inclined in the conveyance direction.

Conventionally, there are various types of this type of hanging and conveying system, and for example, a bottle hanging and conveying apparatus as shown in Patent Document 1 has been created.
This is because a pair of transport chains that translate a pair of guide rails arranged opposite to each other along a transport line suspend and transport bottles, and the transport chains are connected to each other by connecting pins. The pin of the connecting pin that protrudes from the connecting link body and protrudes vertically from the connecting pin hole of the link body and the bottle supporting portion that hangs the bottle by supporting the flange portion protruding from the outer peripheral surface of the bottle protruding from the connected link body A link protrusion guide protrusion provided on the connecting pin, the guide rail is provided continuously with the link body guide groove and the link body guide groove. Is provided with a pin guide groove for guiding in a sliding state.
That is, the bottle can be transported in a suspended state by supporting the flange portion of the bottle from the left and right by the bottle support portions projecting from the plurality of link bodies of the transport chain.

JP 2007-99405 A (see FIGS. 1 and 2)

However, in the conventional bottle suspending and conveying apparatus, there is a difficulty that the bottle itself is largely inclined in the conveying direction when accumulating (the bottle is stopped at a desired position and the conveying chain is moving). It was. Then, there is a possibility that a part of the bottle is deformed or damaged, or there is a possibility that the flange portion is caught in the gap portion between the bottle support portions of the adjacent link bodies {for example, FIG. As shown in (a), when the transported plastic bottle 40 is stopped while the transport chain 50 is traveling leftward, the support protrusion 51 of the transport chain 50 and the plastic bottle 40 are locked. Due to the friction with the flange 41, the mouth of the PET bottle 40 tends to move in the traveling direction of the transport chain 50, and the PET bottle 40 is inclined greatly. At this time, the lower part of the neck portion of the PET bottle 40 is in contact with the lower end surface of the support protrusion 51, and there is a possibility that a part of the PET bottle 40 is deformed or damaged. In particular, when the plastic bottle 40 itself is empty, the plastic bottle 40 is inclined more greatly, and the lower part of the neck of the plastic bottle 40 is more strongly in contact with the lower end surface of the support protrusion 51, so that deformation and damage are more likely to occur. There was a fear. }.
Further, when the bottle diameter is smaller than the distance between the ends of the bottle support portions of the pair of transport chains, there is a difficulty that the bottle is further inclined in the transport direction. There was also a difficulty that the flange portion was more easily bitten in the gap portion {For example, as shown in FIG. 5B, the preform that has been transported while the transport chain 50 is traveling leftward. When 45 is stopped, the mouth of the preform 45 tries to move in the traveling direction of the transport chain 50 due to the friction between the support protrusion 51 of the transport chain 50 and the locking flange 46 of the preform 45. Comes to tilt greatly. At this time, since the body diameter of the preform 45 is smaller than the distance between the tips of the supporting protrusions of the pair of transport chains 50, the preform 45 has a difficulty in tilting considerably. In addition, there is a problem that the locking flange 46 is more easily bitten in the gap portion between the supporting protrusions 51 adjacent to each other. Furthermore, when the gap portion between the adjacent support protrusions 51 is large, the preform 45 may fall due to the locking flange 46 passing through the gap portion. }.

Accordingly, the present invention solves the above-mentioned difficulties and the like, and has a simple structure, easy handling, easy maintenance, suitable for mass production, low cost, and an economical suspended article equipped with a guided apparatus for an object to be conveyed.
