Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can supply device for supplying cans to a conveyor in a conveyor device used for transferring cans from one place to another place.

[0002]

BACKGROUND OF THE INVENTION Conveyor devices are sometimes used to transport cans from one location, such as a supply source, to another location, such as a work location. The can supply device used on the can supply side of such a conveyor device has a can guide, a turret, and a conveyor, supplies the can from the can guide onto the turret, and then the can is transferred from the turret to the conveyor, The cans are transported to the work site by the conveyor.

[0003] In such a conveyor apparatus, however, the conveyor may expand and contract depending on the environmental temperature. For example, if the operation is a baking / drying step of a coating, the conveyor may rise in temperature while passing through a baking / drying oven and may be thermally elongated to cause slack. A tension wheel is attached to absorb the slack, but if the slack is further large, the tension wheel cannot absorb the slack, so shift the position of one of the two wheels around the conveyor Tensions are made.

[0004]

However, as described above, if the positions of the wheels at both ends around which the conveyor is wound are shifted, the positions of the corresponding turrets must also be changed at the same time. It takes time to absorb the thermal elongation. Also, when the position of the turret is changed, the relative position of the can guide changes, so that the delivery of the can is not performed well. In particular, it is necessary to fix the position of the can guide in order to stabilize can transport. Because of this, the thermal expansion of the conveyor can be well absorbed by a simple method, and the thermal expansion of the conveyor can be absorbed while the can guide is installed at the fixed position, and the can from the can guide to the conveyor can be absorbed. There is a demand for the development of a conveyor can supply device capable of performing stable delivery.

[0005] The present invention has been made in view of the above circumstances, and it is possible to satisfactorily absorb the thermal expansion of a conveyor by a simple method, and to maintain the can guide in a fixed position with the can guide. An object of the present invention is to provide a can supply device for a conveyor, which absorbs thermal elongation and can stably transfer a can from a can guide to a conveyor.

[0006]

SUMMARY OF THE INVENTION In response to this object, a conveyor can supply apparatus according to the present invention comprises a can guide at a fixed position, a timing belt device, a first wheel at both ends and a second wheel. Conveyor having a conveyor wound between the wheels and receiving the cans from the can guide to the timing belt of the timing belt device, and then transferring the cans from the timing belt to the conveyor. A device, comprising a fixed frame, a movable frame displaced with respect to the fixed frame, and a driving device for driving the movable frame, the timing belt device and the first wheel supported by the movable frame It is characterized by becoming.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings showing an embodiment. In FIG. 1, reference numeral 1 denotes a conveyor device. The conveyor device 1 includes a can guide 4, a timing belt device 5, a conveyor device 6, and an outlet conveyor device 7 between an inlet 2 and an outlet 3.

The transported can 10 is transferred to the timing belt device 5 and then transferred from the timing belt device 5 to the conveyor device 6. The conveyor device 6 carries the cans into and out of a work place, for example, a baking oven 8.
The cans taken out of the work place are two turrets 11, 1
It is delivered to the outlet conveyor 7 through the outlet conveyor 2 and is carried to the outlet 3 by the outlet conveyor device 7 and carried out. The present invention relates to a can supply device 20 at the inlet 2.

As shown in FIGS. 1, 2, and 3, the can supply device 20 includes a can guide 4 at a fixed position, a timing belt device 5, a conveyor device 6, a fixed frame 31, a movable frame 32, and a frame driving device. 33.

The can guide 4 is a can stocker (not shown).
Is supplied to the timing belt device 5 by guiding the can from the apparatus, and is provided at a fixed position. The timing belt device 5 has a timing belt 24 wound around a driving wheel 22, a driven wheel 21, and an intermediate guide wheel 23 located at both ends.
The timing belt 24 has an attachment 25 as shown in FIG.

The conveyor device 6 has a chain conveyor 28 wound between a first sprocket wheel 26 located at the entry end and a second sprocket wheel 27 located at the exit end. Timing belt 2
4 and the traveling route of the chain conveyor 28 are arranged close to each other in the can supply device 20.

The fixed frame 31 is installed at a fixed position and has a fixed rail 34. On the other hand, a slider 35 is attached to the lower end of the movable frame 32, and the movable frame 32 is placed on the rail 34 of the fixed frame 31 via the slider 35, whereby the movable frame 32 It is displaceably supported. Movable frame 32 and fixed frame 31
Are connected by a frame driving device 33, and the position of the movable frame 32 on the fixed frame 31 is determined by the operation of the frame driving device 33. An air cylinder can be used as the frame driving device 33. On the movable frame 32, the driving wheel 22, the driven wheel 21, and the guide wheel 2 of the timing belt device 5 are provided.
3 is supported, and the first sprocket wheel 26 of the conveyor device 6 is supported.

The operation of the can supply device 20 constructed as described above is as follows. The transported can 10 is transferred from a stocker (not shown) of the can through the can guide 4 at a fixed position to the timing belt 24 of the timing belt device 5 and then received from the timing belt 24 to the chain conveyor 28 of the conveyor device 6. Passed. The chain conveyor 28 transports the cans to a work place, for example, the baking drying oven 8.

Next, the chain conveyor 28 thermally expands and becomes slack, and when it is necessary to remove the slack, the frame driving device 33 is operated to press the movable frame 32 and displace it with respect to the fixed frame 31. . Movable frame 32
, The timing belt device 24 and the first sprocket wheel 26 of the chain conveyor 28 are displaced to give tension to the chain conveyor 28. At this time, the can guide 4 and the timing belt 24 are displaced relative to each other. However, since the timing belt 24 has a straight path 36 in the running path, the can guide 4 is kept in the straight section 36 with the same can delivery condition. Is transferred to the timing belt 24 without any trouble. Timing belt 2
4 and the entrance portion of the chain conveyor 28 move together, so that there is no relative displacement between the two and the conditions for the delivery of cans between the two are kept the same.

As described above, according to the present invention, the thermal elongation of the conveyor can be satisfactorily absorbed, and the thermal elongation of the conveyor can be absorbed while the can guide is installed at the fixed position. A can supply device for a conveyor capable of stably transferring cans can be obtained.
