Description

[Detailed description of the invention] The present invention can be used to
The present invention relates to an improvement of a lifting device in a roller conveyor conveyance system for moving luggage from floor to floor.

Conventionally, in automobile production factories, lifting hangers are used to transport parts such as tires from downstairs (for example, the 1st floor) to upstairs (for example, the 2nd floor), and automatic conveyor roller conveyors are used on the downstairs side. The work was made more efficient by moving the items from there to the automatic roller conveyor upstairs.

As one example of such a conventional device, as shown in FIG. It is composed of a plurality of rollers 3, which are arranged in a pivotal manner, and when going downstairs, it is placed adjacent to the tip of the roller conveyor 4 for automatic conveyance on the downstairs side, and the baggage carried to the tip of the roller conveyor 4 is transferred to the cylinder 5.
There is a system in which the lift hanger is raised after the load is placed on the load placement section 1 by pushing or pulling it in.
Since this conventional device uses a cylinder, the device is complicated and has a large number of parts, and its operation is also complicated, which causes problems such as troublesome operation.

Further, as shown in FIG. 2, a driving belt 6 is provided below the rollers 3', .
There is also a device in which the belt 6 rotates the rollers 3', . Since a power source such as a motor to operate the belt is required, the device becomes complicated and also increases in weight. 2' and 2' are support frames, and 4' is an automatic conveyance roller conveyor.

Although not shown in the drawings, in addition to the above, there was also an automatic transport roller conveyor with an inclined tip so that the cargo could be placed on a lifting hanger.
Since an angle is formed between the roller conveyor and the load placement part of the lifting hanger, and the load is moved by inertia, there is a drawback that the load is subject to impact and there is a risk of the load collapsing. Ta.

Therefore, the present invention has been devised in view of the problems of the above-mentioned prior art, and has a simple structure and ensures that the load is transferred from the downstairs automatic conveyance roller conveyor to the upstairs automatic conveyance without causing any damage. The purpose of the present invention is to provide an elevating and lowering device that can be transferred to a roller conveyor.

Therefore, in the present invention, the folded end on the tip side of the roller drive belt of the automatic conveyance roller conveyor on the downstairs (for example, the first floor) side is made to protrude from the tip of the roller conveyor and extend to the bottom where the lifting hanger is located. At the same time, the cargo loading section of the lift hanger is constructed of a pair of support frames and a plurality of rollers rotatable by the drive of the belt arranged in parallel between the support frames in order to achieve the desired effect. It is designed to achieve a purpose.

The present invention will be described below with reference to an illustrative embodiment.

A pair of support frames 22, 22 having approximately the same width as 14
and a plurality of rollers 23, which are rotatably and pivotally arranged in parallel above between both support frames, and when located below, are adjacent to the tip of the roller conveyor a. The upper surfaces of the rollers 23, . . . and the rollers 15, .
The rollers 23, . . . are configured to rotate by the protruding portions (exposed portions) 7.

Guide columns 24, 24 for guiding the hanger are erected on both sides of the lifting hanger b,
Its upper end passes through a through hole 26 drilled in the ceiling of the first floor, that is, the floor surface 25 of the second floor, and extends close to the ceiling of the second floor. Guide rails 24 are provided on opposing inner surfaces of the guide columns, respectively.
a, 24a protrude along the guide columns 24, 24, and a pair of rotatable guide rollers 2 provided on the side surfaces of both support frames 22, 22 of the hanger b.
The guide rails 24a, 24a are held between the guide rails 7a, 27b so as to roll.

The lifting operation of the lifting hanger b is carried out by a hanger lifting motor block 29 mounted and fixed on a support stand 28 installed across both the pillars 24, 24.
It is designed to be carried out by That is, one end of the wire rope 30 is hooked to the moat block 29, and the other end of the wire rope is hooked to the upper end of the hanger section 21, and by driving the moat block 29, the wire rope 30 is hooked.
is wound up and the hanger b is raised. When the upper surface of the roller 23 of the hanger b becomes flush with the upper surface of the automatic transport roller conveyor 32 on the second floor side, the motor block 29 stops the hanger b. Furthermore, when the hanger is lowered, the motor block is turned off, so that the hanger is lowered by its own weight. In this case, the motor block 29 may be lowered by reversing it. Moreover, when the roller 23 of the lifting hanger b comes into contact with the roller drive belt 17,
Brake is applied so that no impact is applied to the hanger b, belt 17, etc.
