Description

[Detailed description of the invention] The present invention relates to a conveying device.

Conventionally, in a conveying device in which a loaded thin plate (plate thickness 2.5 to 5 mm) is adsorbed by a negative pressure adsorption type conveyor belt and conveyed continuously in the horizontal direction, two thin plates are transferred by the conveyor belt.
~ Three sheets were sometimes attracted and transported at the same time, causing problems in the next process.

Therefore, an object of the present invention is to provide a conveyance device that can reliably convey conveyed materials one by one to the next process.

An embodiment of the invention is shown in FIGS. 1-4.

That is, as shown in FIGS. 1 and 2, this conveyance device includes a lifting device 2 loaded with conveyed materials 1 such as a plurality of veneers, plywood, steel plates, asbestos boards, hard fiberboards, etc. A suction conveyance means 3, such as a conveyor belt of a negative pressure suction type, which is placed above the lifting device 2 and which sucks the upper surface of the uppermost conveyed material 1 and conveys it in the horizontal direction, and a suction conveying means 3, which is installed in parallel with the lifting device 2 and which sucks The apparatus is equipped with an air blowing device such as an air blower/spool 4 for blowing air between the uppermost conveyed material 1 transported by the conveying means 3 and the lowermost transported material 1. In this case, the air blowing nozzle 4 is provided in front of the loaded materials 1 in the transport direction. In addition, in front of the suction conveyance means 3,
A first stopper 5 for preventing the passage of multiple sheets, a second stopper 6 for preventing the passage of multiple sheets, and a roller 7 for preventing the passage of multiple sheets are provided. Only one sheet of conveyed material 1 is sent out. Further, a capstan is provided above between the first stopper 5 for preventing the passage of multiple sheets and the second stopper 6 for preventing the passage of multiple sheets.
3 and 4, a pinch roller 10 that can be raised and lowered by a cylinder 9 moves the conveyed material 1 to the capstan roller 8.
The material to be conveyed 1 is conveyed to the next process by being held between the two. With this configuration, the transported materials 1 can be reliably sent out one by one to the next process in the following manner.

In other words, "the material to be transported 1 loaded by moving up the lifting device 2"
The top surface of the uppermost conveyed material 1 is supported by the suction conveyance means 3, and the uppermost conveyed material 1 is sucked by the suction conveyance means 3 and transferred in the horizontal direction. In this case, since air is blown between the uppermost conveyed material 1 and the lower conveyed material 1 by the air blower/slip 4, two or more transported materials 1 are simultaneously transported by the suction conveyance means 3. It will not be absorbed. In addition, even if two or more sheets are being conveyed at the same time, the first
Since there are a stopper 5 and a second stopper 6, the conveyed materials 1 in the overlapped state are stopped by these.

In particular, since the second stopper 6 is located just in front of the position where the capstan roller 8 and the pinch roller 0 are provided, vertical displacement may occur due to sagging or inclination of the conveyed material 1. Thus, the second stopper 6 is not disengaged from the second stopper 6, and is reliably engaged with the conveyed material 1 below. Therefore, the transported materials 1 are reliably transported one by one to the next process. As described above, the conveying device of the present invention includes a lifting device loaded with a plurality of sheets of transported materials, and a suction device disposed above the lifting device that sucks the upper surface of the topmost transported material and transports it in the horizontal direction. a conveying means, an air blowing device that is installed in parallel with the lifting device and blows air between the uppermost conveyed material transported by the suction conveying means and the conveyed material below it; and conveyance of the suction conveying means. a first multi-sheet passage prevention stopper provided at the front in the direction and whose upper end engages the lower conveyed material when two sheets are conveyed in an overlapping state by the suction conveyance means; A pair of capstan rollers and pinch rollers that pinch the conveyed material from above and below and send it forward. A second plural-sheet passage prevention stopper is provided just before the roller and engages with the conveyed materials below in the case of the overlapping state, so that the conveyed materials are reliably transferred one by one to the next process. It has the effect of being able to be transported.
