Abstract

A transport system (S) comprises a guide path ( 1 ) and at least one mobile carriage ( 2 ) movable along the guide path ( 1 ). The guide path ( 1 ) comprises a first guide profile ( 11 ) and a second guide profile ( 12 ). A single pair of rollers ( 31, 32 ) are mounted rotatably in an independent way to one another on a first rotation shaft ( 51 ) borne by the mobile carriage ( 2 ) so as to be in contact with the first guide profile ( 11 ). A first pair of rollers ( 41, 42 ) and a second pair of rollers ( 43, 44 ) are mounted rotatably in an independent way to one another on a second rotation shaft ( 52 ) and on a third rotation shaft ( 53 ) borne by the mobile carriage ( 2 ) so as to be in contact with the second guide profile ( 12 ).

First claim

The invention claimed is:

1. A transport system for transport of products, comprising:
a guide path and at least one mobile carriage for transport of products movable along the guide path,
the guide path being conformed in such a way as to comprise a first guide profile and a second guide profile, parallel to one another and having an extension that includes at least one straight portion and at least one curved portion,
the first guide profile being conformed in such a way as to have a first rolling wall and a second rolling wall arranged inclined to one another,
the second guide profile being conformed in such a way as in turn to have a first rolling wall and a second rolling wall arranged inclined to one another;
a first rotation shaft borne by the at least one mobile carriage;
a second rotation shaft borne by the at least one mobile carriage; and
a third rotation shaft borne by at least one mobile carriage;
wherein the at least one mobile carriage comprises a first group of rolling members and a second group of rolling members, the at least one mobile carriage being coupled to the guide path so that the first group of rolling members is in contact with the first guide profile and the second group of rolling members is in contact with the second guide profile,
wherein the first group of rolling members comprises a single pair of rollers, the rollers of the single pair of rollers being both mounted rotatably and in an independent way to one another on the first rotation shaft, the rollers of the single pair of rollers being mounted on the first rotation shaft so that a first roller is in contact with the first rolling wall of the first guide profile and in that a second roller is in contact with the second rolling wall of the first guide profile so that when the at least one mobile carriage is moved along the guide path, the first roller can roll along the first rolling wall of the first guide profile independently of the second roller which rolls along the second rolling wall of the first guide profile;
wherein the second group of rolling members comprises a first pair of rollers and a second pair of rollers, the rollers of the first pair of rollers both being mounted rotatably and in an independent way to one another on the second rotation shaft and the rollers of the second pair of rollers being both mounted rotatably and in an independent way to one another on the third rotation shaft, the rollers of the first pair of rollers being mounted on the second rotation shaft so that a first roller of the first pair of rollers is in contact with the first rolling wall of the second guide profile and a second roller of the first pair of rollers is in contact with the second rolling wall of the second guide profile and the rollers of the second pair of rollers being mounted on the third rotation shaft so that a first roller of the second pair of rollers is in contact with the first rolling wall of the second guide profile and a second roller of the second pair of rollers is in contact with the second rolling wall of the second guide profile, so that when the at least one mobile carriage is moved along the guide path, the first roller of the first pair of rollers and the first roller of the second pair of rollers can roll along the first rolling wall of the second guide profile in an independent way, respectively, from the second roller of the first pair of rollers and from the second roller of the second pair of rollers which roll along the second rolling wall of the second guide profile,
wherein the at least one mobile carriage further comprises:
a base plate on which the first rotation shaft, the second rotation shaft and the third rotation shaft are mounted; and
an upright member borne by the base plate, a first support member borne by the upright member and a second support member borne by the upright member, the first support member being arranged transversally to the upright member in such a way as to be facing the base plate, the second support member being removably coupled to the upright member on the opposite side of the upright member with respect to the first support member, wherein the first support member is conformed for hooking and supporting a respective product to be transported and the second support member is conformed for hooking and supporting a respective product to be transported.

2. The transport system of claim 1 , wherein the first rotation shaft, the second rotation shaft and the third rotation shaft are predisposed and mounted on the at least one mobile carriage so as to be parallel to one another.

3. The transport system of claim 1 , wherein:
the rollers of the single pair of rollers of the first group of rolling members have a lateral contact surface with the first guide profile having a truncoconical shape or a spherical cap shape;
the rollers of the first pair of rollers of the second group of rolling members have a lateral contact surface with the second guide profile having a truncoconical shape or a spherical cap shape; and
the rollers of the second pair of rollers of the second group of rolling members have a lateral contact surface with the second guide profile having a truncoconical shape or a spherical cap shape.

4. The transport system of claim 1 , wherein:
the rollers of the single pair of rollers of the first group of rolling members; and
the rollers of the first pair of rollers of the second group of rolling members and the rollers of the second pair of rollers of the second group of rolling members are made of a yielding plastic material.

5. A transport system for transport of products, comprising:
a guide path and at least one mobile carriage for transport of products movable along the guide path, the guide path being conformed in such a way as to comprise a first guide profile and a second guide profile parallel to one another and having an extension including at least one straight portion and at least one curved portion, the first guide profile being conformed in such a way as to have a first rolling wall and a second rolling wall arranged inclined to one another, the second guide profile being conformed in such a way as in turn to have a first rolling wall and a second rolling wall arranged inclined to one another;
wherein the at least one mobile carriage comprises a first group of rolling members and a second group of rolling members, the at least one mobile carriage being coupled to the guide path so that the first group of rolling members is in contact with the first guide profile and the second group of rolling members is in contact with the second guide profile,
wherein the first group of rolling members comprises a single pair of rollers mounted rotatably in an independent way to one another on a first rotation shaft borne by the at least one mobile carriage, the rollers of the single pair of rollers being mounted on the first rotation shaft so that a first roller is in contact with the first rolling wall of the first guide profile and in that a second roller is in contact with the second rolling wall of the first guide profile so that when the at least one mobile carriage is moved along the guide path, the first roller can roll along the first rolling wall of the first guide profile independently of the second roller which rolls along the second rolling wall of the first guide profile;
wherein the second group of rolling members comprises a first pair of rollers and a second pair of rollers, the rollers of the first pair of rollers being mounted rotatably in an independent way to one another on a second rotation shaft borne by the at least one mobile carriage and the rollers of the second pair of rollers being in turn mounted rotatably in an independent way to one another on a third rotation shaft borne by the at least one mobile carriage, the rollers of the
