Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to, for example, a truck bed conveyor for transporting frozen materials.

[0002]

[Prior Art]

 Conventionally, there has been a technique in which a load chain is stretched and a reciprocating drive of the chain is used to load and unload luggage.

[0003]

[Problems to be solved by the device]

 In the prior art described above, the tension of the load chain is adjusted by providing a driven wheel for tensioning the load chain or a tension roller.Therefore, the vertical width for mounting the load chain cannot be easily reduced, and the tension adjustment operation is not possible. There were structural and handling problems such as being troublesome because it was regulated by the loading surface.

[0004]

[Means for Solving the Problems]

 Therefore, according to the present invention, a large number of horizontal rails for carrying luggage are installed between two load chains, and a partition is slidably erected on a guide rail for tensioning and guiding the load chain. A tension bolt is fixed at the lower end in the extension direction of the load chain, and one end is fixed to the lower part of the partition.The other end of the load chain is connected to the tension bolt. The load chain can be attached to the bottom of the load chain more compactly than before, and the load chain can be compactly placed at the bottom of the load chain, and both ends of the load chain can be attached via the tension bolt so that the tension bolt forms part of the load chain. It can be connected and fixed, and the tension bolt mounting structure can be simplified and the tension adjustment operability can be easily improved.

A cooling device for keeping the temperature below a predetermined temperature, (3) and (3) are rear doors for loading and unloading luggage, and the left and right guide rails (4) and (4) and the two central guide rails (5) and (5) The floor plate (6) of (1) is extended and fixed in the front-rear direction on the upper surface, and adjacent rails (4) and (5) are connected and fixed in a lattice shape by a horizontal frame (7), and the upper surface of the frame (7) is fixed. The load receiving frames (8) are stretched in parallel with the rails (4) and (5), and the partitions (10) are slid on the receiving grooves (9) and (9) of the left and right guide rails (4) and (4). The movers (11) (11) are slidably fitted, and the screen (10) is slidably erected on the guide rails (4) (4). There.

Further, the front ends of the guide rails (4) and (5) inside the loading platform (1) are provided with sprockets (13) through a drive shaft (12), and a deceleration case is provided above the drive shaft (12). (14) and an electric motor (15) are provided, the sprocket (13) is rotated forward and backward by the motor (15), and the rear ends of the guide rails (4) and (5) on the rear side of the loading platform (1) are followed. The driving wheels (16) are supported on a free-wheeling axis, and a large number of cross rails (18) on which loads (17) are placed are erected between two load chains (19) (20). As a set, three sets of load chains (19) ... (20) ... form three transfer surfaces (21) ..., and a connector (22) is fixed to the lower part of the partition (10) to drive the driven wheels (16). ) Hanging on the load chain (19) (20) one end side pin ( 23) is connected to the connector (22), and the cross rail (18) is slidably contacted with the synthetic resin belt (24) such as Teflon on the upper surface of the load receiving frame (8) to load the load (17) on the cross rail (18). Is configured to be received by the belt (24).

Further, one end of the tension bolt (25) is fixed to the connector (22), and the other end of the bolt (25) is attached to the rear side of the partition (10) in the extension direction of the load chain (19) (20). An end of a load chain (19) (20) that extends and hangs around a sprocket (13) is connected to the bolt (25) through a pivot body (26), and a bolt (25) is tightened by a tension adjusting nut (27). ) To prevent the pivotal body (26) from coming out, and the tension of the load chain (19) (20) is set by screwing in and out of the nut (27), and one end side of the partition (10) is fixed. The other end side of the guide plate (28) to be fixed is extended above the bolts (19) and (20) substantially parallel to the bolts (19) and (20), and through the long hole (29) of the guide plate (28). Guide plate (28) to pivot body (26) A bolt (30) is fixedly secured to the shaft to prevent the pivot body (26) from rotating around the tension bolt (25).

As is clear from the above, a large number of cross rails (18) on which the luggage (17) is placed are installed between two load chains (19) (20), and the load chains (19) ( The partition (10) is slidably erected on the guide rails (4) and (5) for tensioning and guiding the 20), and the load chains (19) and (20) extend in the extending direction at the lower end of the partition (10). The tension bolt (25) is fixed, and the load chain (19) (20), one end of which is fixed to the lower part of the screen (10), the other end of which is connected to the tension bolt (25). The load chains (19) (20) are connected endlessly through the bolts (25) so that they form a part of the load chains (19) (20), and the load chains (19) (20). The upper side of The feeding part and the lower non-conveying part are slidably guided by the chain guide ridges (31) of the guide rails (4) and (5), and the widths of the front and rear installation parts of the driving part such as the deceleration case (14) are set. When the partition (10) is retracted to the forefront side of the loading platform (1), the drive unit such as the deceleration case (14) is installed by making the projection length of the tension bolt (25) rearward of the partition (10) shorter. The tension bolt (25) is configured to move to the part.

Then, by the forward / reverse control of the motor (15), the partition (10) is reciprocated back and forth through the load chains (19) (20) to and from the loading platform (1), so that the cross rails (18) ... The load (17) to be placed is put in and out via the rear side of the loading platform (1), and the load (17) is stopped and supported by the static friction between the aluminum alloy horizontal rail (18) and the belt (24). The tension of the load chain (19) is adjusted by screwing in and out the nut (27).

The connector (22) and the guide plate (28) are detachably fixed to the lower portion of the partition (10) with a single bolt (32). The connector (22) and the pivot body ( 26) is supported by bolts (25) extending horizontally in the front-rear direction and guide plates (28) to connect both ends of the load chains (19) (20).
