A carrier type conveying apparatus capable of solving a problem in a conventional conveying apparatus wherein a conveying carriers (1) stop abnormally, comprising a rear-pushing traveling district (3) having, at its inlet, a rear-pushing drive means (5A) propelling the conveying carriers (1) at a constant speed and, at its outlet, a speed control drive means (5B) for sending out the conveying carriers (1) at the constant speed and a high-speed traveling district (4). The conveying apparatus comprises carrier connection systems (carrier connection means (9), connection engagement means (10), connection release means (11)). When the conveying carriers (1) travel in the high-speed traveling district (4), the connection of the conveying carriers (1) adjacent to each other in the longitudinal direction by the carrier connection systems is disabled. Only when the conveying carriers (1) travel in the rear-pushing traveling district (3), the conveying carriers (1) in the longitudinal direction are connected to each other by the carrier connection system to prevent the conveying carriers (1) in contact with each other at their end parts from being separated a specified distance or longer from each other.

The invention claimed is: 1. A carrier type conveying apparatus comprising, in a traveling route of conveying carriers, a rear-pushing traveling district having, at an inlet thereof, a rear-pushing drive means for propelling the conveying carriers at a constant speed, and at an outlet thereof, a sp
The invention claimed is: 1. A carrier type conveying apparatus comprising, in a traveling route of conveying carriers, a rear-pushing traveling district having, at an inlet thereof, a rear-pushing drive means for propelling the conveying carriers at a constant speed, and at an outlet thereof, a speed control drive means for sending out the conveying carriers at a first constant speed and a high-speed traveling district in which the conveying carriers exiting the rear-pushing traveling district travel at a second speed higher than the first speed, and a carrier connection system which connects fore and after adjacent conveying carriers to each other, wherein the carrier connection system comprises carrier connection means, a connection engagement means provided at the inlet of the rear-pushing traveling district, and a connection release means provided at the outlet of the rear-pushing traveling district, the connection engagement means switches the carrier connection means at the inlet of the rear-pushing traveling district to connect fore and after conveying carriers whose end parts are in contact with each other, and the connection release means switches the carrier connection means at the outlet of the rear-pushing traveling district to release the connection between the fore and after conveying carriers and disable the connection between fore and after conveying carriers in the high-speed traveling district, and wherein the carrier connection means comprises a connected part provided on either one of the front and rear end parts of each conveying carrier and a movable connector provided on the other of the front and rear end parts of each conveying carrier, and the movable connector can be switched between a connecting position and a connection releasing position and is shaped so as to be held in the connecting position by an urging force and so as not to automatically engage with the connected part when conveying carriers approach each other while the movable connector is at the connecting position, and the connection engagement means switches the movable connector from the connecting position to the connection releasing position and then returns the movable connector to the connecting position in a state that the end parts of the fore and after conveying carriers are in contact with each other to engage the movable connector to the connected part as a connecting mate, and the connection release means switches the movable connector from the connecting position to the connection releasing position, and returns the movable connector to the connecting position after the fore conveying carrier travels at the second speed and separates from the after conveying carrier. 2. A carrier type conveying apparatus comprising, in a traveling route of conveying carriers, a rear-pushing traveling district having, at an inlet thereof, a rear-pushing drive means for propelling the conveying carriers at a constant speed, and at an outlet thereof, a speed control drive means for sending out the conveying carriers at a first constant speed and a high-speed traveling district in which the conveying carriers exiting the rear-pushing traveling district travel at a second speed higher than the first speed, and a carrier connection system which connects fore and after adjacent conveying carriers to each other, wherein the carrier connection system comprises carrier connection means, a connection engagement means provided at the inlet of the rear-pushing traveling district, and a connection release means provided at the outlet of the rear-pushing traveling district, the connection engagement means switches the carrier connection means at the inlet of the rear-pushing traveling district to connect fore and after conveying carriers whose end parts are in contact with each other, and the connection release means switches the carrier connection means at the outlet of the rear-pushing traveling district to release the connection between the fore and after conveying carriers and disable the connection between fore and after conveying carriers in the high-speed traveling district, and wherein the carrier connection means comprises a connected part provided on either one of the front and rear end parts of each conveying carrier and a movable connector provided on the other of the front and rear end parts of each conveying carrier, the movable connector can be switched between a connecting position and a connection releasing position and selectively held at the connecting position and at the connection releasing position by an urging force, the connection engagement means switches the movable connector from the connection releasing position to the connecting position and engages the movable connector with the connected part as a connecting mate in a state that end parts of fore and after conveying carriers are in contact with each other, and the connection release means switches the movable connector from the connecting position to the connection releasing position. 3. The carrier type conveying apparatus according to claim 1, wherein the movable connector is provided with a cam follower part, and the connection engagement means and the connection release means comprise cam rails which act on the cam follower part (39) and switch the position of the movable connector according to the traveling of the conveying carriers. 4. The carrier type conveying apparatus according to claim 1, wherein the connected part comprises an upward hook member, and the movable connector is pivotally supported so as to freely move up and down between the connecting position at a lower limit and the connection releasing position at an upper limit, and is provided with, on its free end side, an engagement part engaging downward with the connected part and a cam follower roller, and the connection engagement means and the connection release means comprise cam rails which act on the cam follower roller and switch the position of the movable connector according to the traveling of the conveying carriers, and on the conveying carrier, a carriage supported while enabled to freely elevate by cross link mechanisms is provided, and in the rear-pushing traveling district, carriage pushing-up rails which push up the carriage via the cross link mechanisms and a carrier floating preventive rail which acts on the cam follower roller of the movable connector to press the movable connector to the connecting position at the lower limit are arranged.
