Description

Transfer device with variable arrangement formation

Technical Field

The utility model relates to a sucking disc moves and carries the device, especially relates to a arrange changeable year device that carries of formation.

Background

The domestic ceramic process flow comprises mud refining, material cutting, roll forming, drying and blank washing, wherein after the blank washing procedure, the ceramic blank on the blank washing machine is transferred to a blank carrying table, and the ceramic blank transferred to the blank carrying table is manually transferred to a blank placing frame for stacking. In order to realize continuous and automatic production, each process flow, such as between the rolling forming and drying process and the blank washing process or after the blank washing process, needs to be provided with a transfer device, and the ceramic blank on the rolling forming machine is transferred to a blank washing machine or the ceramic blank after the blank washing process on the blank washing machine is transferred to a blank carrying table. The transfer device used in ceramic production basically adopts a vacuum chuck transfer device, as described in the patent document disclosed in chinese patent application No. 201520743829.0. In the existing transfer device, the arrangement mode of a plurality of suckers fixed on the transfer device is fixed, such as single-row arrangement or double-row arrangement, and the arrangement formation can not be changed.

However, in the production of ceramics, the conveying mechanism of the roll press is a ring conveying mechanism, when the transfer device sucks the ceramic blanks from the roll press, the ceramic blanks are arranged in a straight line, while the conveying mechanism of the blank washer is a disk conveying mechanism, when the transfer device transfers the sucked ceramic blanks to the blank washer, the ceramic blanks are required to be placed on the blank washer in a circular arc arrangement. In the existing transfer device, in order to adapt to transfer of linear arrangement and circular arc arrangement, only two suckers are usually arranged on the transfer device, namely, the transfer and cutting device can only transfer two ceramic blanks to a blank washing machine from a rolling forming machine each time, the single transfer capacity is small, and the transfer efficiency is low.

Similarly, when the ceramic blanks on the blank washing machine are transferred to the blank carrying table after the blank washing process, although there is no strict requirement on the arrangement of the ceramic blanks placed on the blank carrying table, the transfer device can take out a plurality of ceramic blanks arranged in an arc shape on the blank washing machine, and then directly transfer the ceramic blanks arranged in the arc shape to the blank carrying table. However, in this transfer mode, since the ceramic blanks are placed on the blank carrying table in an arc arrangement, the blank carrying table is generally required to have a wide width and a wide floor area, which is not favorable for the discharge and spatial layout of each device in the ceramic production workshop.
