Abstract

PURPOSE:To prevent the interference-breakage of a glass tube and allow the conveyor speed to coincide with the speed of the next process by loading each glass tube onto the supporting hooks arranged at equal intervals on the feeding- side conveyor which travels continually and transferring the glass tube onto the receiving-side conveyor through a plurality of inclined chutes on one side midway on a vertical traveling passage. CONSTITUTION:Each glass tube (a) is supported onto the glass-tube supporting hooks 1 installed in equal pitch onto the feeding-side conveyor A onto stripes of endless chains 2. The inclined chutes C1 and C2 are arranged in two stages in close to the top edge of the hook 1 in the leading-out part E of the conveyor A. Solenoid valves midway in air feeding pipes 4 and 4 are opened and closed intermittently corresponding to the pipe (a) feeding speed and the feeding pitch of the conveyor A, and the pipes (a) which reach the positions of the inclined chutes C1 and C2 are discharged by the injection force of the high-pressure air supplied from nozzles D1 and D2, and sent onto the receiving-side conveyors B1 and B2 at the lower edges of the chutes C1 and C2. Therefore, the pipe (a) can be prevented from interference-broken, and the conveyor speed can be allowed to coincide with the processing speed in the next process.

Description

[Detailed description of the invention] Industrially small and friendly! The present invention relates to a mechanism for automatically transferring glass tubes from a vertical supply conveyor that continuously runs in the vertical direction to a plurality of other conveyors.

BACKGROUND OF THE INVENTION Conventionally, the configuration shown in FIG. 3 has been most commonly used to transfer glass tubes from one conveyor to another. That is, in FIG. 3, (A) is a supply side conveyor, (B) is a receiving side conveyor, and an inclined shoe (C) is provided between both conveyors (A) and (B), and the supply side conveyor is The glass tube (a) being conveyed by the side conveyor (A) is sequentially transferred to the inclined shoe (C) using the reversing position on the feeding end side of the supply side conveyor (A), and the glass tube (a) is transferred to the inclined shoe (C). a) is transferred onto the receiving plate side conhair (B) and conveyed.

In the conventional transfer mechanism described above, the position where the glass tube (a) is taken out from the supply conveyor (A) is at the feed end side of the supply conveyor (A). Only one reversal position can be used, so when the glass tube (a) supplied from the supply conveyor ('A) is transferred to the receiving conveyor (B) in a direction parallel to the tube axis. In this case, compared to the feeding pinch of the glass tube (a) on the supply side conveyor (A), the conveyance pitch on the receiving side colveyor (B) is a long pinch corresponding to the length of the glass tube (a). Conveyor (B
), there is a risk that the previous glass tube (a) and the next glass tube (a) will collide with each other and cause damage. A
) Even if it were to be made larger, there was a limit to it. Therefore, in the conventional transfer mechanism, there is no choice but to align the glass tube feeding directions of the supply side conveyor (A) and the receiving side conveyor (B) in the same direction, and the feeding direction cannot be freely selected. There was a problem in that it was not possible to take out the glass tube (a) from (A) at multiple locations.

This invention is equipped with glass preamble receiving claws at equal intervals, and a plurality of slopes for taking out glass tubes on the mid-way side of the vertical running path of the continuously running supply conveyor. The chutes are fixedly arranged, a receiving conhair is associated with the lower end of each inclined chute, and a glass tube is connected to the upper end of each inclined chute from the glass receiving claw of the outlet section of the supply conveyor to the inclined chute side. Either an air injection nozzle is provided to transfer the glass to the glass front plate, or the length of the glass front plate catcher is changed stepwise, and the starting end position of each inclined chute is adjusted in steps to correspond to the change in the length of the glass front plate catcher. By changing the length so that the glass tubes are received into the inclined chute in order from the long glass preamble receiving claw, it is possible to freely select the feeding direction of the receiving conveyor, and it is also possible to take out glass tubes from the supply conveyor from multiple locations. I hope it's something you can do.

FIG. 1 shows a first embodiment of the present invention, in which (A) shows a vertical supply conveyor, (B1) and (B2) show a receiving side conveyor, and (C1 and C2) show an inclined chute. .

The supply side conveyor (A) has glass preamble receiving claws (1) attached to an endless chain (2) at equal intervals, and has a lead-out part (E) for the glass tube (a) in a part of the running path. In FIG. 1, the endless chain (2) is shown schematically by a single line. This endless chain (2) consists of two parallel and interlockingly driven chains, each chain is provided with glass front catch claws (1) at equal pitches, and the glass tube <a> is held at two locations in the tube axis direction. Support it horizontally. In FIG. 1, the glass front plate receiving claw (1) is shown in an oval shape, but it may have another shape.

Each inclined chute (CI) (C2) is arranged in two stages at the lead-out part (E) of the glass tube (a) of the supply side conveyor (A), and the position of the inclined starting end (upper end) is determined by the glass tube support claw. Although it does not interfere with the glass tube (a,) being conveyed by (1), it is placed close to the tip of the claw (1).

Corresponding to the starting end of each inclined chute (CI) ((,2), the support frame (3
) The air injection nozzle (Dt) (D2 is fixedly installed in the air injection nozzle (Dl) (D2).
4) It is connected to a high-pressure air supply source (not shown) through (4), and a solenoid valve (not shown) is inserted between each of them. (a)
The glass tube <a> that has arrived at the position of each inclined chute (C1)' (C2) is injected with high-pressure air to the inclined chute (C1) (C2) side by opening and closing intermittently according to the feeding speed and pitch of It is released with a jetting force of . The injection timing of each air injection nozzle (Dl) (D2) is such that the injection timing is such that the glass tubes (a) supported by the glass preamble receiving claws (1) provided at equal intervals on the supply side conveyor (A) are alternately One air injection nozzle (Dl) intermittently releases odd-numbered particles, and the other air injection nozzle (D2) releases even-numbered particles. It is timed to release intermittently. This timing is achieved by detecting the pitch of the support type electrically with the switch and opening/closing the solenoid valve.
There are various methods such as

In addition, each air injection nozzle (Dl) (D2) is provided with an injection force adjustment valve (5) (5), and the clamp member (6) (6) of the air supply pipe (4) (4) is The support frame (3) via the mounting bracket (7) (7) with
) is fixed and adjustable in position.

The receiving side conhairs (B+) (B2) are arranged corresponding to each of the inclined lower ends of the above-mentioned inclined chutes (CI) (C2), and in the example of FIG. 1, the glass tube (a) is placed parallel to the tube axis. Although the case is shown in which it is conveyed in one direction, it may be conveyed in another direction.

FIG. 2 shows a second embodiment of the present invention, in which the supply side conveyor (A) has long and short glass bone receiving claws (la) (
Ib) are alternately provided at equal intervals, and the inclined shoes)
) (C2) is different depending on each overlap, and the one with the long claw (1a) is first scooped out with a chute and taken out.

In both of the above-mentioned embodiments, the parts are disposed in two stages at a supporting type pitch and taken out, but it is also possible to provide two or more stages. For example, in the first embodiment, it is possible to install a plurality of sets including the air injection nozzle, the inclined chute, and the receiving conveyor, and in the second embodiment, the length of the glass bone receiving claw is changed stepwise, and the starting end position of each inclined chute is changed stepwise in accordance with the change in the length of the glass osteodermal receiving claw, so that the glass osteodermal receiving claw is received in order from the longest glass osteodermal receiving claw to the inclined chute side. Just do it.

In this invention, the glass tube is taken out from the middle of the vertical path of the supply conveyor, so the glass tube outlet can be selected at any position, and there are multiple receiving conveyors. Furthermore, there is an advantage that the conveyance direction of the taken out glass tube can be freely selected. Therefore, from the supply side conveyor that conveys the glass tube in a direction perpendicular to the tube axis,
When transferring glass tubes to a receiving conveyor that is conveyed in a direction parallel to the tube axis, interference and damage to the glass tubes can be prevented, and the speed of the receiving conveyor can be adjusted to the next step without being restricted by the speed of the supply conveyor. For example, it has excellent advantages such as being able to match processing speeds such as packaging processes.
