Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which glass tubes are grouped by a predetermined number, and a buffer material is interposed between the grouped glass tube arrays to form a package. The present invention relates to a packaging device for glass tubes that is automatically laminated. 2. Description of the Related Art In general, a glass base tube continuously manufactured in a glass tube manufacturing process is cut into predetermined lengths, and after cutting, a predetermined inspection (appearance, dimensions, shape, scratches, etc.) is performed. ) Is performed, and the glass tube determined to be defective is sorted out and removed.
The glass tube is sent to the packing process by a conveyor in a state where the defective product is missing in some places, and is sequentially stacked and packed in a packaging container. When sequentially laminating and packing glass tubes sent by a conveyor to a packing process in a packaging container, missing defective products are randomly present, so it is necessary to absorb the missing glass tubes. Therefore, conventionally, a predetermined number of glass tubes corresponding to one layer are accumulated on a fixed amount rail, and a fixed rail is installed in front of the fixed amount rail, and when a fixed number of glass tubes are accumulated on the fixed amount rail, A device that closes the gate, supports the subsequent glass tube on the fixed rail, prevents entry into the fixed amount rail, transfers the glass tube on the fixed amount rail to the transfer table, and packs through the transfer table. Has been proposed (for example, see Japanese Patent Application Laid-Open No. 51-95359). [0004] In the conventional apparatus, glass tubes continuously fed by a conveyor are accumulated in a continuous state on a fixed rail and a fixed amount rail. In some cases, flaws were generated or the end face was lost due to the inclination of the glass tube. Therefore, under the present circumstances, an operator receives glass tubes sent by a conveyor one by one, inserts and arranges the glass tubes in a packaging container each time, and laminates and packs the glass tubes. Although it is inserted and interposed, this requires a large labor burden on the operator and poor workability. SUMMARY OF THE INVENTION It is an object of the present invention to prevent a glass tube from being damaged while preventing the glass tube from being conveyed by a conveyer, to collect a predetermined number of glass tubes, and to interpose a predetermined number of glass tubes between rows. It is an object of the present invention to provide a packing device for glass tubes that is automatically stacked and accommodated in a packaging container with a buffer material interposed. [0007] In order to achieve the above object, the present invention conveys glass tubes one by one in parallel via attachments attached to endless chains at predetermined intervals.

Is detected, and when there is a glass tube, the two separator shafts are rotated once to stop the glass tube. When there is no glass tube, the glass tube is set to stop and wait until the next glass tube is conveyed. The above-mentioned glass is provided with a fixed-quantity take-out mechanism and a buffer material having a concave portion for partitioning and supporting a predetermined number of glass tubes at a pitch corresponding to the glass tube receiving pitch of the separator shaft. Glass tube conveying quantitative extraction mechanism

It means the downstream side in the glass tube transport direction. The presence / absence of a glass tube which is supported and conveyed by the attachment of the supply conveyor is detected by a glass tube detection sensor, and when there is a glass tube, the two separator shafts are rotated once to stop. When there is no glass tube, a glass tube fixed quantity take-out mechanism is provided to stop and wait the two separator shafts until the next glass tube is conveyed. The glass tube can be taken out. A predetermined number of glass tubes taken out by the glass tube fixed amount take-out mechanism are transferred onto the buffer material on the relay stand by the transfer mechanism, and further stacked and housed in the packaging container from the bottom by the stacking mechanism. This operation is repeated to stack and store up to a predetermined number of layers, and the packaging container is discharged to supply the next packaging container, and the glass tube is similarly stacked and stored. The packaging containers stacked and stored up to a predetermined number of layers and discharged are covered and bundled before being shipped or stored. The glass tube supplied from the supply conveyor is:
Since each of the glass tube fixed quantity take-out mechanism, the transfer mechanism, the relay stand, and the laminating mechanism is partitioned and supported one by one, damage is prevented. Needless to say, even in the packaging container, one by one is supported in each row by the cushioning material to prevent damage. In particular, since the glass tube and the buffer material are stacked and housed together in the packaging container, the glass tube and the buffer material can be stacked and housed regularly with a simple configuration.
