Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyance device capable of reversing an object to be conveyed during the conveyance process.

BACKGROUND OF THE INVENTION In various conveying devices for conveying articles, there are cases where the article must be turned upside down during conveyance for subsequent processing steps and the like.

For example, in a reversible fan caser in which the contents are taken out by inverting the box with the closing part facing downward, the empty box after separating the contents is placed with the opening part facing upward for the next packaging process. It is necessary to turn it around again and send it out. Such a conveying device is required to have a configuration as simple as possible and to convey the material while performing reversal processing reliably and at high speed due to restrictions such as the equipment layout of the entire factory or processing time. In view of the above points, the present invention has been made for the purpose of providing a conveyance device which has a simple configuration and is capable of conveying an object while continuously reversing the object. An inorganic belt is hung around the endless belt, and a transfer section for applying the conveyed object to the endless belt is pivotally supported, and a twisted transport path is provided around the endless belt to engage and guide the transport member. An inner guide member and an outer guide member provided with a twisted and curved guide plate corresponding to the twisted transfer path are set in duplicate, and the guide plates of the inner guide member and the outer guide member are This is intended to twist and guide the conveyed object, which is biased and transferred by the transfer member.

Hereinafter, the present invention will be explained based on an example in which the present invention is applied to an inversion type surveyer.

FIG. 1 shows the entire reversible anchor, in which 1 is a supply conveyor and 2 is a synchronous conveyor, which consists of a feeding member and a box-shaped guide member, which are stretched between chains on both sides at a required interval. A control mechanism (not shown) is disposed between both conveyors 1 and 2, and the boxes continuously conveyed from the supply conveyor 1 are supplied one by one to each destination village of the synchronous conveyor 2 by the control mechanism. 3 is a well-known flap opening mechanism arranged on a synchronous conveyor, which opens each flap on the top surface of the box as the box is transferred.

Reference numeral 4 denotes an inverting device that inverts the box with the top flap opened by the flap opening mechanism 3 while holding the contents.

Reference numeral 5 denotes a content conveyor disposed at the outlet of the reversing device 4, and 6 a side flap receiving guide, which extends upward obliquely to the conveyor 5. The box body is pulled up by the synchronous conveyor 2 along the side flap receiving guide 6. Both conveyors 5, 2 and guide 6 transport the separated contents and the box, respectively. 7 is a conveying device according to the present invention, which inverts the box body with the closing part facing downward by the reversing device 4, and then inverts the box body again with the closing part facing upward, and transfers it to the next process, the box word process. It is meant to be transported.

Details of this conveyance device 7 will be explained with reference to FIGS. 2 to 7. As shown in FIG. 2, until the box C is pushed by the sending member 8 and transported to the entrance of the transport device 7, the flaps F on both sides are raised horizontally by the side flap receiving guide 6, and the box C is moved forward and backward. The front flap F is opened upwardly from the rear flap date fixing plate 101 by the rotary cam 9.

The rotating cam 9 consists of a rotating shaft 9a rotatably supported on the fixed side and a semicircular cam plate 9b fixed to the rotating shaft ga, and the horizontal position of the cam plate 9b is at the center of the hanging flap F. Its shape is such that the front side in the rotational direction of the central portion 9c is inclined downward, and the height of the front end portion is located slightly above the lower end of the flap F. The rotation of the cam plate 9b is synchronized with the conveyance of the box C, and when the front flap F passes the position of the rotating shaft 9a, the cam plate 9b rotates at a higher speed than the moving speed of this flap F to carry it. Push from the rear and release upwards (see Figure 3). The end of this pushed-up front flap F is located above the fixed plate 10.
Now, the box C whose front flap F has been pushed up is moved onto the fixing plate 10 while being pushed by the sending member 8. The end of this fixed plate 1 is slightly inclined downward, so that the rear flap F can be easily engaged and opened upward. As schematically shown in FIG. 7, the conveying device 7 includes a cylindrical inner guide member 11 with an oval cross section, and a cylindrical outer guide member 12 surrounding the cylindrical inner guide member 11 and having a similar surface. It is equipped with

As will be described later, the box C has both guide members 11 and 1.
While passing through the space with a donut-shaped cross section defined by 2, it is turned over and discharged with the closed part facing upward. The inner guide member 11 is longer than the outer guide member 12 and protrudes forward in the conveyance direction by approximately the length of one box C,
A discharge conveyor 13 is disposed from below this protruding portion to further forward. 14 and 15 are inner guide members 11
A pair of rotating shafts 16 and 15 are rotatably attached to the front and rear ends of the sprockets 16 and 15, respectively.
The chain 18 is wound in the direction of arrow A via a drive source (not shown) (see FIG. 7).

Rods 19 are pivotally supported on the chain 18 at predetermined intervals. The rod 19 is rotatable only in a plane perpendicular to the direction of movement of the chain 18, and its tip always protrudes from a guide slit 20 formed in the inner guide member 11.
As the chain 18 rotates, the guide slit 201 is engaged and moved. Therefore, the guide slit 20 is formed on the upper surface side of the inner guide member 11 on the entrance side of the device, and has a semicircular shape with approximately the same diameter as the sprocket 16 with the support portion of the rotating shaft 14 as the center. Furthermore, on the outlet side, the inner guide member 11 has a semicircular shape having approximately the same diameter as the sprocket 17, centered on the support portion of the rotating shaft 15 formed on the lower surface side of the inner guide member 11. In the guide slit 20', on the side of the inner guide member 11,
The above two semicircles are obliquely inclined with respect to the horizontal plane for feeding, and when viewed as a whole, the inner guide member 11 has an endless shape wound diagonally from the entrance side to the exit side. ing. That is, while the chain 18 rotates between the sprockets 16 and 17, the rod 19 attached to the chain 18 engages the two guide slits and rotates, and its tip end is connected to the inner guide member 11. Swing from the top surface to the bottom surface and from the bottom surface to the top surface. On the other hand, inside the outer guide member 12, there is provided a pair of side guide plates 22 corresponding to the guide slits 201 from the inlet side to the outlet side, and the distance between these guide plates 22 is set from the width of the box C. It is set slightly larger. Therefore, the box C can move while twisting between these guide plates 22, and this movement is as follows.
This is done by inserting iron into the box C so that the protruding portion of the rod 19 from the inner guide member 11 is pressed from behind. In addition, in FIG. 7, the side guide plate 22
is not shown for simplicity. Since this device has the above-mentioned configuration, it operates in the following manner to reversely move the box C.

The box C, which has been pushed by the feeding member 8 and forced with the opening facing downward, is first pushed forward with the front flap F by the rotary cam 9 and transferred onto the fixed plate 10. As the box body C moves forward, the rear seven wraps F come into contact with the fixing plate 10, and are thereby pushed up rearward. Box C is feeding member 8
The rod 19 is pushed into the space between the inner guide member 11 and the outer guide member 12, and the rod 19 is inserted into the box C.
As the box C is carried in (see FIG. 4), the sending member 8 changes direction upward to open the box C. Next, the box C is transferred while rotating between the pair of guide plates 22 while being energized by the rod 19 (see Fig. 5), and when it reaches the outlet of the device, the opening is directed upward. Discharge conveyor 1
On the other hand, the rod 19 comes out from inside the box C and returns to the entrance side via the chain 18.

Each flap F of this box C engages with the inner guide member 11 and maintains the open state until it is twisted and transferred by this device and transferred onto the conveyor 13. Therefore, after the reversal, the flap F does not close due to its own restoring force, and there is no need to open the flap F again before filling the contents. In the above embodiment, while the box C is transferred from the left side to the right side in FIG. 2, the inner guide member 11 is transferred from the upper side to the lower side and reversed. It is possible to reversely move it upward. Therefore, both the reciprocating motion of the rod 19 can be used for twisting conveyance, and in order to avoid interference between conveyed objects that pass each other at the entrance and exit of this conveyance device, four sprockets 23 are installed as shown in FIG. It is also possible to increase the width B of the entire feeding layer. Furthermore, it goes without saying that the present invention can also be applied to a box washer.

As described above, according to the present invention, at least a pair of rotating members are supported on a fixed frame in a rotational manner, a rotatable endless band is rotated by these rotating members, and a rotating endless band is pivotally supported by the endless band. a transfer member; an inner guide member provided with a twisted transfer path defined around the endless band for engaging and guiding the transfer member; and the twisted transfer path spaced apart from the inner guide member; an outer guide section having a guide plate along the route, and a torsion mechanism in which the conveyed object, which is biased and transferred by the transfer member, is made to follow between the inner guide member and the guide plate of the outer inner member. The conveyed object is guided by the engagement bias of the transfer section along a fixed twisting guide path formed by the surface of the inner guide member and the guide plate of the outer guide member. It is possible to reliably and smoothly invert and transfer, and especially when the box that has avoided the flaps is twisted and transferred along the inner guide member, the flaps that are opened at the time of inversion are restored and closed. This has the effect of allowing an efficient reversing operation to be performed without any friction.
