Description

[Detailed description of the invention] Conveyance device for goods capable of bulk handling In this invention, the conveyance groove is arranged in a spiral shape between the centers. at least partially immersed in a liquid disposed around and contained in a container The present invention relates to an article conveying device that is equipped with a vibrating conveyor and is capable of bulk handling. During ~ The structural unit consisting of the central cylinder and the conveying groove has a vibration drive unit installed outside the container. It is attached. In this type of equipment, the liquid contained in the container must be protected from the surrounding atmosphere. Must be. For example, electrolyte for aluminum plating is removed from oxygen and moisture in the air. or the surrounding atmosphere from hazardous vapors of the liquid. do not have.

For surface treatment of bulk-handled articles, e.g. cleaning or pickling or electroplating. Items that can be handled in bulk along an upwardly leading conveying groove for plating A helical conduit that transports items such as bolts, washers or nuts through the treatment liquid under vibration. Bear can be used.

Known metal bulk electroplating equipment does not allow bulk handling of materials passing through the treatment bath. A vibrating conveyor with horizontal and vertical vibration components is installed to transport the products. Ru. This vibrating conveyor uses inertia to move the material upward in a spiral conveying groove. Bulk-handled items are conveyed around a columnar central tube connected to a groove. . The vibrating conveyor is placed in an airtight container containing the electrolyte together with the pillars, and the conveyor A central tube with a central tube is partially immersed in this electrolyte. Vibration is reduced by the drive unit. Items that can be easily lifted up and can be bulk handled must be periodically vibrated to gain height. is transported through the electrolyte in the transport direction. This kind of vibrating conveyor is relatively small It just requires a lot of driving force. Strong movement and good electrolyte exchange and dispersed Provides uniform current input over the entire active surface of bulk-handled articles . The conveying groove of the vibrating conveyor can be vibrated via the central tube. In that case The central tube has a spiral shape that serves as a support structure for the conveying groove as well as for vibration transmission. The conveying groove leading upwards around the periphery of the It is attached to the central tube located in the center. And the excitation is driven by vibration at a small expense. (see German Patent Application Publication No. 3524510) ).

Another conventional example of a vibratory conveyor similarly handles bulk-handled items to be processed. This conveyor groove is equipped with a conveyor groove for this purpose! l! II spirally arranged around the central cylinder, It is partially immersed together with the central cylinder in the electrolyte contained in the container. bulk handle The supply of ready-to-drink items takes place via a drop tube, allowing for bulk handling. A conveying channel leads out of the open container above for the removal of the articles. The central cylinder is transported Connected as an anode along with grooves and bulk-handled articles and containing electrolyte The metal lining of the inner wall of the container is connected as a cathode. Center cylinder and conveyance groove? The vibrating component consists of a vibration drive consisting of two vibrating heads. These vibrating heads are arranged facing each other on the circumference of the upper end of the central cylinder. Ru. In this conventional example, the vibrating drive is easily accessible, but both vibrating heads are synchronized. must be adjusted and adjusted. The structural unit consisting of the central cylinder and the conveying groove has a capacity together with the electrolyte and the electrolyte to form an open device which, for example, contains a water-free electrolyte. Not suitable for processing bulk-handled items inside (U.S. (See US Pat. No. 3,649,490).

An object of the present invention is to simplify the known structure of a conveying device for bulk-handled articles. It consists in simplifying and improving. Especially for configurations with easily adjustable drives, for example for closed devices containing electrolytes sensitive to oxygen and/or water. It is something that

In this invention, a vibrating structural unit consisting of a central cylinder and a conveying groove is mounted in a stationary container. Based on the knowledge that a closed device is obtained when the device is successfully sealed against the This problem is therefore solved by the features of claim 1. This configuration A simple design for hermetically closed equipment for the processing of goods that can be handled in bulk. A simply adjustable drive is obtained and a water-free electrolyte is used in the device. Can be done.

In one embodiment, the seal can be made of flexible plastic. Furthermore, the container A special configuration of the seal with a shaft sealing ring can be provided between the lid and the central tube. one of these rings is responsible for sealing against the corrosive vapors of the electrolyte. , the other is responsible for sealing against atmospheric intrusion.
