Problems solved by technology

[0010] These problems are by no means unique to escalators, but are common to the structure in which joints and holes are provided on two plate-shaped members, and are typical problems in conveying equipment in which multiple joints and holes are formed.

Embodiment 1

[0030] figure 1 It is an external view showing what is called an escalator, which is a passenger conveyor as an example of transportation equipment to which the present invention is applied. This escalator is composed of a step 8 that moves endlessly from the floor of the lower floor to the floor of the upper floor, and handrails 3 erected on both sides (only one side is shown).

[0031] In addition, the handrail 3 is equipped with: a handrail rubber belt 2 that moves synchronously with the movement of the pedal 8; .

[0032] figure 2 It is a structural diagram showing the armrest frame of this embodiment. The handrail frame is a structure in which a U-shaped frame 1A holding the shape of the handrail rubber belt 2 and a C-shaped frame 1B fixing the panel 3 a of the handrail 3 are overlapped. Punching and plastic connection are simultaneously performed on the overlapped surfaces drawn in an S-shape in the longitudinal direction to form the hole 10 and the plastic connecti...

Embodiment 2

[0049] In this example, not only Figure 4 The relationship between the height difference H between the front ends of the punching punch 11 and the plastic connecting punch 20 and the thickness T of the overlapping workpiece 5 and workpiece 6 is H>T, and when H<T Take this as an example.

[0050] In the structure of this embodiment (not shown), if the punch plate side of the metal die set is pressurized, as in Embodiment 1, since the punch 11 for punching and the punch 21 for plastic connection are loaded The same punch hits the plate and therefore starts moving towards the die side at the same time. In addition, since the punch 11 for punching protrudes toward the mold side than the punch 21 for plastic connection, the punching process starts earlier. Then, since the overhang amount H is smaller than the plate thickness T, the punch 21 for plastic connection starts to pressurize the workpiece 5 during the punching process, and the plastic connection also starts. In additio...

Abstract

The invention relates to the shape of a plate-shaped part and a method for manufacturing the plate-shaped part, a conveying device and a method for manufacturing the conveying device, and an automatic escalator. The subject of the invention is that the distance precision between the center of a plastic connecting part and the center of an opening part is inadequate when the opening part and the plastic connecting part are disposed on the plate-shaped part. When punched hole parts and plastic connecting parts are formed on two plate-shaped parts, a punch and a mould are arranged for the punched hold parts and the plastic connecting parts. The punch for punching punches earlier than the plastic connection, and the plastic connection is completed during the punch for punching entering the processed material.

Description

technical field [0001] The present invention relates to the shape of a plate-like member and its manufacturing method, a conveying device and its manufacturing method, and in particular to an escalator. Background technique [0002] As an example of a method of fixing two sheets of metal used in conveying equipment, for example, Japanese Patent Application Laid-Open No. 11-147683 (Patent Document 1) discloses the following content: In the example of an escalator, the railing of the passenger conveyor is made of alloy The handrail frame made of board is made by overlapping the surface side frame for holding the handrail rubber belt and the back side frame for holding the balustrade made of glass plate, and joining them by resistance welding, and processing the joint surface for Hole for fastening bolts etc. to the escalator casing. [0003] In addition, there is Japanese Patent Publication No. 6-16908 (Patent Document 2) as one of the methods of overlapping and joining two a...
