Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a new and improved object transfer device, particularly for transferring an upright object such as a bottle onto two adjacent transfer surfaces. The present invention relates to a transfer device that can smoothly move objects over steps.

In general, in order to automatically seal the contents of a packaging container such as a bottle, attach a label, and perform other operations, it is necessary to continuously move the container in an upright position along a certain path.

There are various means for transporting these upright objects, but in particular when transporting upright objects by stacking them on a conveyor or by sliding objects on a sliding surface, these transfer surfaces are generally limited. Because of the length, multiple transfer surfaces must be laid in succession in order to obtain a colinear transfer path of a given length. However, when a plurality of transfer surfaces are installed in succession, a certain amount of space or a step is inevitably formed between adjacent transfer surfaces, so that an upright object that moves between adjacent transfer surfaces must be placed within the above-mentioned distance. They had the disadvantage of being prone to falling over when climbing over stairs or steps, which could lead to unexpected accidents. SUMMARY OF THE INVENTION The present invention provides a new and improved object transfer device which overcomes the disadvantages of the prior art transfer devices described above, and which provides a new and improved object transfer device which provides an arrangement for moving objects between adjacent transfer surfaces. A screw for feeding an upright object such as a bottle is arranged along the traveling direction of the screw, and a guide rail is arranged opposite to the screw to engage the upright object with the groove of the screw, and regarding the screw, The trough of the screw at the boundary between the two transfer surfaces is made relatively narrower than the theoretical trough of a normal upright object, and when the upright object moves through the boundary, the upright object is forcibly tilted in the twisting direction of the valley groove. It is characterized by allowing

To explain the present invention in detail below, the object transfer device of the present invention is composed of a feeding screw and a guide rail which are arranged oppositely above the object transfer surface as described above, and an upright object such as a bottle is transported by a screw and a guide rail. and is engaged with the groove of the feed screw by a guide rail,
It is transferred on the transfer surface as the screw rotates.

The upright object transferred on the transfer surface in the device of the present invention is
It is forcibly tilted at the boundary between adjacent transfer surfaces in order to overcome the gap or level difference formed between the adjacent transfer surfaces, but this is the case when referring to the superconductor feeding screw. This is achieved by making the trough relatively narrower than the theoretical trough of a normally erected object. This trough changes from a deep circle where the upright object engages with the trough of the screw.Therefore, in the present invention, the trough of the screw at the boundary between two adjacent transfer surfaces is normalized. To make the upright object narrower than the theoretical trough means to deepen the engagement depth of the upright object with this trough when the shape of the screw root groove is constant; In order to keep the engagement depth of the upright object in the groove constant, it is necessary to actually narrow the valley, but when exploring any of the above-mentioned forms, the normally upright object is tilted along the twist of the screw. Next, the device of the present invention will be explained in detail based on the attached drawings. First, the first diagram illustrates the schematic configuration of the main parts of a typical embodiment of the device of the present invention. As is clear from the drawing, this device consists of a screw turtle for feeding an upright object and a guide rail 2 installed opposite it.

The screw shaft is made of a synthetic resin material that has excellent lubricity with respect to the upright object 3 such as a bottle, and the depth of the grooves a is uniform over the entire length of the screw.

This screw also serves as a surface for transporting the upright object 3, such as a conveyor or a dead body. If it is placed above a moving surface such as a plate and as close to the transfer surface as possible, it will be rotated by a suitable drive mechanism 41.
On the other hand, the guide rail 2 is also made of the same synthetic resin material as the screw, and is arranged opposite to the screw at a distance such that the upright object 3 can be pushed into the groove a of the screw.

This guide rail 2 is supported by a plurality of guide stands 5, and in order to deeply engage the upright object 3 in the groove of the screw at a predetermined position, that is, near the boundary p between two adjacent transfer surfaces, the guide rail 2 is The distance between the screw member and the screw member is narrowed by a distance adjusting mechanism.The apparatus shown in FIG. / Or it can be installed above the second transfer surface consisting of a dead five-plate drum arranged with a step, or as shown in Figure 4, a transfer surface consisting of a conveyor and a step on the It is used by being installed above a transfer surface consisting of a dead G plate 8' which is arranged with a horizontal axis.

Therefore, in FIGS. 3 and 4, the conveyor y,
? The upright objects 3 transferred by ' are initially shallowly engaged with the grooves la of the screw turtle, and are moved to the right in the drawing while being normally erected on the first transfer surface. The standing object 3 is the bulging portion 9 of the guide rail 2
As a result, the upright object 3 is deeply engaged with the groove la of the screw 1, and accordingly, the upright object 3 is forcibly inclined in the torsional direction of the groove of the screw.

At the same time as the upright object is tilted, the forward end of the bottom of the upright object in the direction of movement is lifted, so that the object can easily overcome the gap or step between the transfer surfaces and reach the dead plates 8, 8.
′ will be moved up. The object 3 transferred onto the dead plates 8, 8' is again shallowly engaged with the screw 11, and is slid and transferred onto the dead G plate by the screw in a normal upright state. Next, FIG. 2 shows another typical embodiment of the device of the present invention,
In this device, the screw cap for feeding upright objects and the guide rail 2 are arranged facing each other with a parallel interval maintained, and the feeding screw 11 is located near the boundary p between two adjacent transfer surfaces. The middle W of the valley groove 11a is smaller than the valley WJ on both sides thereof, and ``this valley W' corresponds to the theoretical valley for normally standing up the object 3.

The apparatus shown in FIG. 2 is used by being installed above two adjacent transfer surfaces as shown in FIGS. 3 and 4, and in this case, the upright The object engages with the groove of the screw and is moved to the right in a normal upright state, and then is forcibly tilted in the direction of the torsion of the groove turtle a at the middle W of the valley, and the object is moved in the direction of movement of the bottom of the erected object. The front end of the side is lifted and this object 3 easily overcomes the gap or gap between the transfer surfaces and becomes dead.

Plate 8 is transferred onto the wing'. The object 3 that has been transferred onto the dead plate is again in a normal upright state and is slid on the dead plate by the screw. As explained above, according to the device of the present invention, when transferring an upright object such as a bottle onto an adjacent transfer surface, the object can be easily moved over the gap or step formed between the two transfer surfaces and smoothly. Because it can be moved, it can effectively prevent the upright object from falling when it is transferred between the transfer surfaces, and prevent various troubles caused by the upright object falling over.Therefore, its practical value is extremely great. be.
