Abstract

PURPOSE:To regulate the direction of deformable container smoothly and reliably by providing a cam member to be engaged with a rotary drive mechanism to rotate an engaging member by predetermined angle while providing an engage selection member at the engaging portion of said cam member and rotary drive mechanism. CONSTITUTION:Engaging members 5 are provided rotatably on each of many mount bases 4 stretching over a chain 3 of carrying means 1 then the bottom of deformable container 2 is fitted to said member 5. When carrying the container 2 under this state, a detector at the uppermost stream will detect the direction of container 2 and upon detection of incorrect direction an engage selection member 30 is lifted by means of a cylinder 31. Consequently, a cam follower 24 travelling over the linear cam section 26 is engaged with an arched cam section thus to rotate the engaging member or the container 2 by 90 deg. through arm section 22, unilateral clutch 21, etc. While detectors at the downstream will function to convert the attitude of container 2 as required thus to correct the direction.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a direction adjustment device for a deformable container, and more specifically, a device for adjusting the direction of a deformable container, in which a deformable container having a deformed part such as a rectangular or elliptical shape on the body is aligned in a certain direction. Regarding equipment.

Conventionally, a direction adjusting device for a deformable container that aligns the direction of the deformable container while continuously conveying the deformable container usually includes a conveying means for conveying the deformable container, and an engaging member that engages with the container and is integrally transferred. , a rotation drive mechanism that rotates the engagement member to rotate the container, and a detector that detects the direction of the container, and the rotation drive mechanism rotates the container based on a detection signal from the detector. The container is rotated or not rotated to align the container in a predetermined direction.

Conventionally, as the rotational drive mechanism, a dedicated motor is provided, a common drive source is provided, and an electromagnetic clutch is provided in each drive system of the drive source and the engagement member.
Alternatively, while the deformable container is rotated by frictional force, an engaging portion provided at a predetermined position of the deformable container is engaged with a stopper provided at a predetermined position to forcefully stop the container. Proposed. However, in a rotary drive device with such a configuration, the motor and electromagnetic clutch are expensive, and on the other hand, in a device in which the engaging part of the deformable container is brought into contact with the stopper, the container may be damaged or deformed, or the container may fall. There were issues such as the need for special consideration.

In view of these points, it is an object of the present invention to provide a direction adjusting device for a deformable container that is simple in construction and does not damage the container by using a cam mechanism as a drive source.

The present invention will be explained below with reference to the illustrated embodiments.
In Fig. 2, ■ is a transport means for transporting the deformable container 2 (see Figs. 4 and 5), consisting of endless chains 3 arranged parallel to each other and a large number of mounts installed between both chains 3. The deformable container 2 can be transported in a state where the bottom part of the deformable container 2 is fitted into a retaining member 5 rotatably provided on each mount base 4.

As shown in FIGS. 4 and 5, the deformable container 2 is equipped with a body 6 having a rectangular cross section and a handle 7, and is transported by a transport conveyor (not shown) provided upstream of the transport means 1. It is conveyed with fixed guides guiding both sides of the recording body 6, and is synchronized with each engaging member 5 by a timing screw (not shown), so that the bottom of the body 6 with a rectangular cross section is connected to the engaging member. It is fitted into the rectangular recess 8 of No. 5. Note that the probability that the deformable container 2 faces in the normal direction when the deformable container 2 engages with the engagement member 5 is electric.

However, in FIG. 3, the engaging member 5 is rotatable via a bearing 10 provided in the mount base 4 that is stretched between the pair of chinos 3 and the cylindrical case 9 that is fixed to the mount base 4. A lifting rod 11 is provided on the shaft portion of the engaging member 5 so as to be rotatable relative to the engaging member 5.

A plate 12 for receiving the bottom surface of the deformable container 2 is rotatably attached to one end of the lifting rod 11. It is designed to be raised and lowered by Further, a cam follower 14 is attached to the lower end of the lifting rod 11 via a bracket 13, and the cam follower 14 is engaged with a cam member 1B fixed to a machine frame 15. Further, the bracket 13 has a rotation IF member 17 slidably passed therethrough, and the rotation prevention member 17 is fixed to the lower part of the cylindrical case 9 so as to be parallel to the lifting rod 11.

Therefore, when the cam follower 14 is moved up and down according to the cam curve of the cam member 1B as the chino 3 moves, the plate 12 is moved up and down via the bracket 13 and the elevating rod 11. And this play)
12 has a height that matches the upper surface of the engaging member 5 at its rising end position, and in this state, the deformable container 2 is placed on top of the 12 (play).
When supplied, the plate 12 is lowered to position the bottom of the body 6 of the deformable container 2 within the recess 8. Moreover, once the direction of the deformable container 2, which will be described later, is aligned in a predetermined direction,
Thereafter, the plate 12 is raised again to allow the bottom of the deformable container 2 to be discharged from the recess 8 to the outside.

Next, a clutch case 20 is disposed inside the cylindrical case 9.
This clutch case 20 is interlocked with the engaging member 5 via a one-way clutch 21. This one-way clutch 21 is configured to transmit only one direction of the reciprocating rotation of the clutch case 20 to the engaging member 5. Then, a bracket (23) disposed vertically is fixed to an arm portion 22 provided integrally with the clutch case 20, a cam follower 24 is provided at the lower end of this bracket 23, and this cam member is fixed to the machine frame 15. 25 is engaged.

As shown in FIG. 1, the cam member 25 includes a linear cam portion 26 that is along the conveying direction of the conveying means l and does not rotate the retaining member 5 via the clutch case 20.
and three arcuate cam parts 27, 28, and 28, each of which has a starting point and an end point continuous with the cam part 26, and rotates the engaging member 5 by 80 degrees in a predetermined direction, and A cam follower 24 that engages the cam member 25 at each starting point of the arcuate cam portion 27, 28, 28.
Engagement selection members 3o for selecting whether to engage the linear cam portion 28 or the arcuate cam portions 27, 28 are provided so as to be movable up and down.

This engagement selection member 30 is connected to the machine frame 1 as shown in FIG.
The cam follower 24 is moved up and down by a cylinder device 31 provided at the cam member 5, and at its rising end position engages with the linear cam portion 26 of the cam member 25 and travels.
In order to forcibly engage the arcuate cam part 27, 28 or 29, the linear cam part 20 downstream of the connection part is closed and the L-shaped member is continuous with the arcuate cam part. There is.

Then, on the upper surface of the mount base 4, a stopper is pressed against the outer circumferential surface of the cylindrical engaging member 5 and engages with flat portions 32 formed at four locations on the outer circumferential surface to hold the engaging member 5 in that position. A mechanism 33 is provided. Therefore, although the one-way clutch 21 is used, the cam follower 24
is normally held at a constant position, and when the engagement selection member 30 is located at the lower end position, the cam follower 24 does not engage with the arcuate cam portion 27, 28 or 28. It comes to run on the linear cam portion 26.

Note that the arm portion 22 integrally provided to the clutch case 20 is held in a predetermined position by a spring or the like, and the cam follower 2
4 may be held at a position where it normally engages with the linear cam portion 2B.

Furthermore, a detector 35, 36, 37 consisting of a phototube for detecting the direction of the deformable container 2 is provided at the connection portion between the starting point of each of the arcuate cam portions 27, 28, 28 and the linear cam portion 2C.
As shown in FIG.
The handle 7 is arranged so as to detect the gap between the handle 7 and the handle 7. Therefore, when each of the detectors 35 to 37 can detect light, the deformable container 2 is facing in the normal direction, and when the detectors cannot detect light, it is facing in another direction. This means that Each of the detectors 35 to 37 is configured to output a signal to the cylinder device 31 to raise the engagement selection member 30 when it cannot detect light. When the deformable container 2 whose bottom part is fitted into the engaging member 5 passes the most upstream detector 35, the direction of the deformable container 2 is detected by the detector 35, and the direction is changed to the normal direction. When facing, the engagement selection member 30 is located at the lower end position, so the cam follower 24 runs on the linear cam portion 2B without being engaged with the arcuate cam portion 27. In this state, the engaging member 5 is not rotated, and the deformable container 2 is conveyed to the downstream side while facing in its normal direction, and is similarly transported to the detector 3B.

37 and is discharged outside while facing in the normal direction.

On the other hand, if the detector 35 detects that the deformable container 2 is not facing the normal direction, the detector 35 detects that the deformable container 2 is not facing the normal direction.
The cylinder device 31 is actuated by the signal from 5, and the engagement selection member 30 is raised, and the cam follower 24 that has traveled on the linear cam portion 26 is forcibly engaged with the arcuate cam portion 27 by the engagement selection member 30. be made to match.

As a result, when the arm portion 22 and the clutch case 20 are rotated in a certain direction by the cam curve on the inlet side of the arcuate cam portion 27, the engaging member 5 is rotated in that direction via the one-way clutch 21. and rotate the deformable container 2 by 80 degrees. - When the arm portion 22 and the clutch case 20 are rotated in the opposite direction by the cam curve on the exit side of the arc-shaped cam portion 27, the engaging member 5 and the deformable container 2 are rotated in the opposite direction by the one-way clutch 21. rotation in the direction is prevented.

Furthermore, when the deformable container 2 passes through the detectors 36 and 37 on the downstream side, the orientation of the deformable container 2 is detected in the same manner as described above, and the engagement selection member 30 is raised ten degrees depending on the orientation.
Alternatively, the deformable containers 2 are held at the lower end position, one of the two types of operations described above is repeated, and finally all the deformable containers 2 are oriented in the normal direction, and in this state they are discharged to the outside. It becomes like this.

On the wood flow side, if the requirements on the downstream side change and the direction of the handle 7 of the container 2 needs to be changed, it is possible to simply change the direction of the handle 7 of the container 2 without changing the rotation drive mechanism etc. There is an advantage that the requirement can be easily met by simply changing the positions of the detectors 35-370.

In addition, on the actual flow side, the cam member 25 has a linear cam portion 2.
6, but this linear cam portion 26 can be omitted if necessary. In addition, it goes without saying that the arcuate cam parts 27 to 29 may be provided in a number corresponding to the shape of the deformable container. When aligning towards
It is sufficient to provide one arcuate cam portion. In this case, if the deformable container 2 is discharged to the outside while aligned in the normal direction, and then the retaining member 5 is reversely rotated to return to the original rotation position, the above-mentioned one-way Clutch 21 can be omitted. Furthermore, although the deformable container 2 is conveyed in a straight line in the above embodiment, it is also possible to configure it as a rotary type.

As described above, the present invention includes disposing a cam member that engages with a rotational drive mechanism and rotates the engaging member by a predetermined angle along the conveyance locus of the engaging member, and 1. In the part that connects to the rotational drive mechanism,
Since an engagement selection member is provided that selects engagement or disengagement between the cam means and the rotary drive mechanism in response to a detection signal from the detector, the configurations of the rotary drive mechanism and the cam member can be changed. It can be made simpler than the conventional method, and the effect that the container will not be damaged can be obtained.
