Abstract

PURPOSE:To facilitate direction regulation by detecting the direction of deformed containers to regulate the direction of the container through the engagement of any of a plurality of locating pins provided according to the contour of the deformed container thus selected with stopper members on a container engaging member. CONSTITUTION:When deformed containers 11 are supplied on a turntable (not shown) in a rotor 1 from a transfer conveyer through a star eheel, an ascending engaging member 12 descends to engage a shoulder of the container 11. Then, before the container 11 is supplied onto the turntable, the direction of the container 11 is detected by a plurality of detectors so that cylinder units 57-60 are operated to select locating pins necessary for directing the container 11 in the normal direction from a plurality of locating pins 31-34 disposed on the periphery of a stopper member 30 rotated integrally with the engaging member 12. And the deformed container 11 is adapted to be directed in the normal direction by the engagement of selected locating pins with the stopper member 30.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a direction regulating device for a deformable container, and more specifically, a direction regulating device for a deformable container that aligns deformable containers having a rectangular or elliptical body portion in a certain direction. Regarding.

Conventionally, a direction regulating device for a deformable container that aligns the direction of the deformable container while continuously transporting the deformable container has been used, for example, with a transport means for transporting a deformable container having a rectangular cross section, and a device that engages with the deformable container and is integrally transported. a retaining member; and a rotation drive mechanism that rotates the deformable container by rotating the retaining member,
The detector detects the direction of the deformed container and the direction is I.
When the direction is not in the F direction, there is a device in which the rotation drive mechanism is used to rotate the rotation drive mechanism sequentially by 90 degrees.

In this type of direction regulating device for a deformable container, the direction of the deformable container is detected once at a time to detect whether or not rotation is necessary.
It is necessary to provide a detector in the cylinder, which makes the device complicated and large, and the deformable container rotates intermittently, resulting in slow processing speed.

In view of these points, the present invention includes a plurality of positioning pins that engage with the damper member provided integrally with the engagement member and forcibly stop its rotation, corresponding to the shape of the deformable container. The rotational behavior of the deformable container is provided at a location, and the deformable container is supplied to this with the engaging member at the standard rotational position, and the orientation of the deformable container is detected in advance and corrected based on this. The corresponding positioning bin can be held in the above-mentioned stomper member (<1 position, and in this state, the engagement member is rotated and the rotation of the engagement member is stopped by the positioning bin, so that the deformable container can be placed in the regular position. With this configuration, the direction of the deformable container can be adjusted simply by detecting the direction of the deformable container and positioning the corresponding positioning pin so that it can be engaged with the stomper member. An object of the present invention is to provide a direction regulating device for a deformable container, which can set the direction of the deformable container to be the normal direction, and can therefore have a simple configuration and a high processing speed.

At this time, the second engaging member 12 is in the upward position A, and when the deformable container 11 is supplied to the rotary table L, the engaging member 12 descends and engages with the shoulder portion of the deformable container 11. Then, as will be described later, all the deformable containers are transformed by the required rotation of the retaining member 12.]
When the direction of
From there, it is discharged onto a conveyor 24.

A positioning force of 1.3 is provided in the middle of the
By bringing the cam follower 37 into elastic contact with the cam follower 37 at 6 with a spring (not shown), each of the positioning pins 31 to 34 can be set to a non-engaged position in which the positioning pins 31 to 34 are not engaged with the stopper member 30, and a engaged position in which they are engaged with the stopper member 30. It is possible to position it in the same way.

1- Two cam followers 40 to 47 are attached to each of the crime positioning pins 31 to 34, and one cam follower 40 to 43 of each of the positioning pins 31 to 34 controls the rotation of the rotating body 1 from the star wheel 27 on the discharge side. direction ji

These fixed cams 48 to 51 are provided on a supporting member pa integral with the identification +i2, and among the fixed cams 48 to 51, the fixed cam 48 that engages with the positioning pin 31 serving as a reference raises the positioning pin 31. , the fixed cams 48 to 51 that engage with the other positioning pins 32 to 34 are
It is now possible to make 2-34 into 1-11.

Therefore, when the engaging member 12 passes through the star wheel 27 on the discharge side and takes out the deformable container 11 by υ1, the positioning pin 31 serving as a reference is moved by the fixed cams 48 to 51.
is at an engagement position where it engages with the stopper member 30, and the other positioning pins 32 to 34 are at non-engagement positions where they do not engage with the stopper member 30. Then, due to the rotation of the drive gear 22 which is rotating with the rotation of the rotating body 1, the friction flange 2

2 is rotated, and when the stopper member 30 rotating in contact with the engaging member 12 comes into contact with the positioning pin 31, the rotation of the stopper member 30 and the engaging member 12 is forcibly stopped. As a result, the engaging member 12 is positioned at a predetermined reference position.

On the other hand, 1; the other cam followers 44 to 47 provided on each of the crime positioning pins 31 to 34 are disposed at positions slightly forward in the rotational direction of the rotating body l than the star wheel 2G on the supply side in 1-. The movable cams 53 to 56 act as second positioning means, and each i
The +l moving cams 53-56 are respectively linked to the shilling devices 57-60 via appropriate link mechanisms.

Then, each of the movable cams 53 to 56 is connected to a shilling device 57 to

As a result, each of the positioning pins 31 to 34 passes through the movable cams 53 to 56 that are interlocked with the silling devices 57 to 60 without engaging them, and at that time, the locating pins 31 to 34 pass through the movable cams 53 to 56 that are interlocked with the silling devices 57 to 60, and at that time, Since the stopper member 30 that rotates together with the mating member 12 contacts the positioning pin 31 and remains positioned at a predetermined reference position, the deformable container 11 is not rotated by the engaging member 12 in any way and is moved to the discharge side. from the star wheel 27 onto the conveyor 24.

On the other hand, - the deformable container 1 is detected by the detectors 61 to 63.
If the control device 64 determines that it is necessary to rotate the deformable container 11 by, for example, 270 degrees in the rotational direction of the engagement member 12 in order to orient the deformable container 11 in the iE direction, the control device Reference numeral 64 denotes a shilling device 5 that is interlocked with a movable cam 53 that engages with a reference positioning pin 31.
7 is actuated, the cylinder device 60 of the movable cam 56 engages with the positioning pin 34 which is 270 degrees out of phase with the positioning pin 31 in the rotational direction of the engaging member 12.

Then, the TTf movable cam 53 moves the reference positioning pin 31 to one of the non-locking positions, so that the stopper member 30 is moved by the positioning pin 31.
is released, the engaging member 12 rotates, and the deformable container 1
Rotate 1. At the same time or before this, the positioning pin 34 is positioned at the engagement position by the movable cam 56, so that when the stopper member 30 rotates 270 degrees, it engages with the positioning pin 34 and is stopped. As a result, the rotation of the deformable container 11 is also stopped. In this state, the deformable container 11 is oriented in the normal direction.

Thereafter, when the deformable container 11 approaches the discharge side star wheel 2'7, the retaining member 12 is raised by the aforementioned cam 15, and the deformable container 11 is placed on the conveyor 24 by the star wheel 27. And deformed container 1
1 is ejected, each of the positioning pins 31 to 34 comes to pass through the fixed cams 48 to 51, and as described above, the positioning pin 31 serving as a reference is moved to the stopper member 3o by the fixed cams 48 to 51. The other positioning pins 32 to 34 are in the engagement position where they engage with the stopper member 3.
0, the engaging member 12 is returned to the predetermined reference position.

In addition, in the above embodiment, the drive gear 22 and the fixed tooth medium 23
