Description

[Detailed Description of the Invention] The present invention relates to a pneumatic carrier, and particularly to an opening/closing structure of the pneumatic carrier.

A pneumatic carrier used in a pneumatic carrier device that pneumatically transports items between separated stations or between a transmitting station and a receiving station is usually a cylindrical pneumatic carrier with an opening at one end. It consists of a child body and a cap that opens and closes the open end of the pneumatic feeder body, and conveyed articles can be taken in and taken out from the open end. In such pneumatic carriers, it is necessary to open and close the open end of the pneumatic carrier main body with a cap each time an article is loaded into the pneumatic carrier or an article is removed from the pneumatic carrier. Therefore, the structure for attaching and detaching the cap must be such that the opening end can be opened and closed easily and quickly from the viewpoint of efficiency of pneumatic pumping, and the cap must not fall off during pneumatic pumping.

In view of the above-mentioned requirements, various structures have been proposed for attachment/detachment of the cap for opening and closing the open end of the air sender body, including a screw type or a tube fitting type. However, many of the conventional air carriers are
When the opening end is opened, the cap is removed from the pneumatic body, and there is therefore a risk that the cap may be lost when it is removed from the pneumatic body.

The present invention allows the open end of the pneumatic sender body to be opened and closed easily and quickly, and allows the cap to be securely attached to the pneumatic sender main body, while also eliminating the risk of the cap being removed from the pneumatic sender main body and being lost. The purpose of the present invention is to provide an improved pneumatic carrier that is free from leakage.

According to the present invention, the present invention has a pneumatic sender main body having a cylindrical open end at one end, and an annular edge portion that fits into the open end of the pneumatic sender main body in a cylindrical manner. In the pneumatic carrier, the pneumatic carrier has a generally disc-shaped cap that selectively opens and closes the open end, and the pneumatic carrier main body and the cap have a first shaft portion that is substantially perpendicular to each other. and a second shaft portion, the first shaft portion is attached to the air sender body about an axis offset from the center of the open end substantially parallel to the central axis of the open end. the caps are rotatably mounted on the cap and movably along the axis thereof, and the second shaft portion engages the cap substantially along one diameter of the disc-like shape, thereby connecting the caps to each other; and the cap is arranged in a position where the edge portion is fitted into the open end in a cylindrical manner and closes the open end, and when the edge portion is removed from the cylindrical fit with the open end and the first shaft is moved toward the open end. The cap is pivotable around an axis of the cap to open the open end, and the first shaft is biased by a spring in a direction to move the cap toward the open end. This is achieved by using a pneumatic pouch that is characterized by:

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is an overall view, partially in cross section, of the pneumatic carrier according to the present invention with the open end closed, Fig. 2 is a sectional view showing the main parts of the air carrier with the open end open, and Fig. 3 is the open end open state. It is an end view in the state. In these figures, reference numeral 1 indicates a cylindrical air sender main body, and the air sender main body 1 is open at one end. A cushion member 2 made of felt is attached to the other end of the air sender main body 1, and cushion rings 4 made of felt are attached to the vicinity of both sides of the outer periphery by annular members 3 made of rubber. ing.

5 indicates a cap. The cap 5 has a cylindrical portion 6 that fits into the outer periphery of the open end of the pneumatic sender main body 1 in a cylindrical manner, and is configured to selectively open and close the open end 1a of the pneumatic sender main body 1. The fitting length between the pneumatic body 1 and the cap 5 is the annular end wall 6 of the cylindrical portion 6.
The length is regulated by a, and the length may be about 10 mm in a general pneumatic carrier.

The pneumatic sender main body 1 has three holes 7, 8, and 9 on one axis extending parallel to the axis of the pneumatic sender main body 1 in the peripheral wall near the open end. rotates the shaft member 10 around its axis, that is, around the open end 1
It is received so as to be rotatable around an axis offset to one side from the center of a and movable in the axial direction. The shaft member 10 has a hook shape bent at a substantially right angle, and has one portion 10a that engages with the holes 7 to 9, and the other portion 10b that extends in the radial direction of the cap 5. The cap 6 is connected to the pneumatizer main body 1 by engaging with the holes 5a and 5b provided therein. A snap spring 1 is attached to the free end of the portion 10a of the shaft member 10.
1 and the ring member 12 locked by the part 1
A compression coil spring 14 is installed between the ring member 13 which is attached to the ring member 0a so as to be movable in the axial direction and engages with the end wall portion of the air balloon main body 1. The member 10 is urged to the right in the drawing, that is, in the direction in which the cap 5 fits into the pneumatic body 1 in a cylindrical manner. A portion 10b of the shaft member 10 extends in the radial direction of the cap 5, crosses the recessed portion 5c of the cap 5, and forms an operating portion of the cap.

As shown in FIG. 1, when the cap 5 is fitted into the pneumatic body 1 in a cylindrical manner and the open end 1a is closed, when opening the open end 1a, the operator must Grasp the pneumatic carrier body 1 with one hand, and use the other hand to hold the operating portion 10b of the shaft member 10.
, and move the cap 5 in the axial direction of the portion 10b to the left in the figure against the spring force of the compression coil spring 14, so that the cap 5 is inserted into the pneumatic sender main body 1. Pull it out from the cylindrical fitting, and in this state, rotate the cap 5 approximately 180 degrees around the axis of the portion 10a.
degree, and release it by aligning it with the open end 1a. As a result, the open end 1a of the pneumatic carrier body 1 is opened as shown in FIGS.
The state is now ready for loading of articles to be transported.

In addition, in order to close the opening end 1a from the open state as shown in FIGS. 2 and 3, the cap 5 must be moved approximately toward the pneumatic body 1 around the axis of the portion 10a. Rotate it 180 degrees and align it with the open end 1a. Cap 5 is open end 1a
When aligned, the cap 5 moves to the right in the figure together with the shaft member 10 due to the spring force of the compression coil spring 14, and the cap 5 is fitted into the air body 1 in a cylindrical manner, and the open end 1 is closed. become. The cap 5 is fitted into the pneumatic feeder main body 1 in a cylindrical manner, and is given a force in the fitting direction by the compression coil spring 14, so that the opening end 1a does not open during pneumatic feeding. do not have. In addition, in the unlikely event that an axial force is applied to the cap 5 in a direction away from the pneumatic feeder body 1 during pneumatic feeding, this force moves against the action of the compression coil spring 14, causing the cap 5 and the pneumatic feeder body 1 to move. Even if the tube-type fitting is separated, the cap 5 is prevented from rotating around the axis of the portion 10a of the shaft member 10 by the inner wall of the pneumatic tube, and the cap 5 is prevented from rotating around the axis of the portion 10a of the shaft member 10. Since the axial movement amount is restricted to an appropriate length by the shaft member 10, the pneumatic body 1
It does not open to the extent that the conveyed articles inside fall out from the opening end 1a.

Furthermore, even when the opening end 1a is open as described above, the cap 5 is connected to the pneumatic carrier main body 1 by the shaft member 10, so there is no risk of it being lost.

In the above-described embodiment, the pneumatic body 1 and the cap 5 are connected by the spring force of the compression coil spring 14.
Although it was configured to maintain a cylindrical fit with the
The present invention is not limited to this, but is configured such that the tube-type fitting is selectively maintained by providing an appropriate spring-type engaging portion on the tube-type fitting portions of both. may have been done.
