Material box and automatic feeding device

Abstract

The invention relates to a material box and an automatic feeding device which are used for vertically placing a plurality of fixing pieces. The fixing pieces are straight fixing pieces or bent fixingpieces, each bent fixing piece comprises a straight line section and a bent section, the material box comprises a bottom plate, a front limiting plate and a rear limiting plate are arranged on the bottom plate in the width direction of the fixing pieces at an interval, a left limiting plate and a right limiting plate are arranged on the bottom plate in the length direction of the fixing pieces atan interval, the straight line sections are arranged on the bottom plate, the bent sections are arranged in a suspended mode, a pushing opening is formed between the front limiting plate and the bottom plate, and a discharging opening only allowing the single fixing piece to go out is formed between the rear limiting plate and the bottom plate. The automatic feeding device comprises the material box, a driving mechanism used for pushing out the lowermost fixing piece in the material box through the discharging opening, and a material receiving mechanism used for receiving the fixing pieces pushed out of the discharging opening. The material box and the automatic feeding device have the advantages of being reasonable and compact in structural design, capable of automatically conveying the straight fixing pieces or the bent fixing pieces, better matched with a numerical control nailing machine, safe and reliable in operation and the like.

Description

Technical field: [0001] The invention relates to the technical field of door and window processing equipment, in particular to a material box and an automatic feeding device. Background technique: [0002] The fixing piece (also called the connecting piece or the installation piece or the connecting piece) is one of the indispensable parts in the installation of doors and windows, and mainly plays the role of fixing the doors and windows on the wall. In order to improve the processing efficiency of doors and windows, it is generally necessary to install the fixing piece on the door and window profiles in advance. In the past, the installation of the fixing piece was mainly done manually. During the installation, the installation position was marked on the door and window profiles in advance, and the fixing piece was placed on the door and window profiles according to the mark, and then nailed with an electric screwdriver. This installation method is not only labor-intensive ...

Problems solved by technology

However, the problem of how to realize the automatic feeding of the fixed sheet has been puzzling the relevant researchers.

[0003] In order to realize the automatic feeding of the fixed sheet, various attempts have been made in the prior art, but there are always some unsatisfactory parts. The scheme that the fixing piece is directly and quickly installed on the nailing mechanism, and then the CNC nailing machine takes the fixing piece and nails directly on the door and window profiles, which realizes the semi-automatic feeding of the fixing piece, but manual feeding is still required; another example is the existing technology Disclosed is a mechanism that can realize automatic feeding along the length direction of the fixed piece (referred to as the horizontal feeding mechanism). The specific structure is as follows: Figure 11 As shown, the horizontal feeding mechanism includes a horizontal feeding channel arranged horizontally, and a horizontal feeding material box for placing the fixed sheet is arranged on the horizontal feeding channel. There is a material outlet, the size of the outlet can only allow one fixed piece to pass through, and a horizontal feeding driving cylinder is provided at one end of the pushing port. Although the horizontal feeding mechanism can realize the feeding of the fixed piece, there are three prominent Problem: First, it can only feed the straight fixed piece, but cannot feed the curved fixed piece. The existing fixed piece is divided into two types: straight fixed piece and curved fixed piece, such as Figure 12 As shown, a straight plate means that the entire surface is flat; as in Figure 13 As shown, the curved fixing piece refers to bending at about 1 / 4 of the length of the fixing piece to divide it into two parts: a straight section and a bent section. In the same plane, the main function of the curved fixed piece is to facilitate the rotation of the fixed piece during installation, so the curved fixed piece is more widely used; second, due to the use of horizontal transportation, the horizontal length of the entire structure is too long, which is very inconvenient to use , the structure is not compact enough; the third is that due to the long distance of horizontal conveying and the long length of the push plate, it is easy to deform after long-term use, which eventually leads to jamming and even the problem of popping out the fixed piece

Through the analysis of the existing improvement scheme, it can be known that there is no mature scheme in the existing technology that can realize the automatic feeding of the fixed piece, so it is necessary to design a new automatic feeding device, which can not only realize the automatic feeding of the straight fixed piece, but also It can realize the automatic feeding of the bending fixed piece, and the structure design is more reasonable and compact at the same time
