Description

  The present invention relates to a conveyor connecting device for smoothly transferring a conveyed product to another conveying device on the downstream side in a connecting portion of the conveyor.

  Conventionally, a gap is formed in the arc part of the end of the conveyor in the transfer part of the conveyor, and the conveyed product may fall into the gap or be tilted by the gap, resulting in a hindrance to the conveyance. In order to smoothly transfer to another transport device, a conveyor connecting device having a transport roller in the gap is known.

The conveying rollers of these conveyor connecting devices are not driven as a free roller or are rotated by an independent driving device.
That is, as shown in FIG. 14, in order to transfer the conveyed product 700 from the upstream conveyor 600 to the downstream conveyor 601, it is used for conveyance as a free roller in a gap portion formed in an arc portion at the end of both conveyors 600 and 601. As shown in FIG. 15, in order to transfer the conveyed product 700 from the upstream conveyor 600 to the downstream conveyor 601, as shown in FIG. 15, in the gap portion generated in the arc portion at the end of both conveyors 610 and 611, It is known that a transfer roller 510 driven by a motor 511 controlled in synchronization with the moving speeds of the conveyors 610 and 611 by a control device 620 is installed. (For example, refer to Patent Document 1).

A conveyor connecting device provided with a plate that covers a further gap generated before and after the conveying roller is also known.

  However, in such a conventional conveyor transfer device, when the conveying roller is not provided with a driving force as a free roller, the conveyed item is moved by being pushed by the conveyed item flowing from behind, so that the intermittent item is intermittent. During conveyance and final conveyance, there is a problem that the conveyance object stagnates on the conveyor transfer device or that the posture of the conveyance object is disturbed or falls due to contact between the conveyance objects. However, since the size and complexity of the apparatus increases, there is a problem that the burden of maintenance increases and the burden of rearrangement of the transport line also increases.

  Therefore, the problem to be solved by the present invention, that is, the object of the present invention is to solve the problems of the prior art as described above, and the conveyor roller is driven with a simple structure to connect the conveyor. The present invention provides a conveyor connecting device for smoothly transferring a conveyed product to another conveying device on the downstream side.

  The invention according to claim 1 is provided between a conveyor device that conveys a conveyed product on the upper surface of a conveying chain or belt, and another conveying device adjacent to an end portion of the conveyor device. In the conveyor transfer device including a transfer roller for transferring a transfer object, the transfer roller is provided in at least two rows and driven in a transfer direction by a drive transmission roller provided on a lower surface thereof, and the drive The transmission roller is driven in contact with the conveyor conveyance surface rotating portion at the end of the conveyor device, thereby solving the above-mentioned problem.

  According to the second aspect of the present invention, in addition to the configuration of the conveyor connecting device according to the first aspect, the conveying roller is directly contacted with the driving transmission roller and driven in the conveying direction by friction transmission. This further solves the above problem.

  According to the third aspect of the present invention, in addition to the configuration of the conveyor connecting device according to the first aspect, the conveying roller is free to rotate with a stepped shaft having a large-diameter portion at an end. The above-mentioned problem is further solved by being fitted and the large-diameter portion of the stepped shaft coming into contact with the drive transmission roller and being driven in the conveying direction by frictional transmission.

  In addition to the configuration of the conveyor transfer device according to any one of claims 1 to 3, the invention according to claim 4 is provided with three or more rows of the conveying rollers, and the drive transmission. The above-mentioned problem is further solved by driving the transport roller not driven by the driving roller in the transport direction from the transport roller driven by the drive transmission roller via the drive transmission belt.

  The conveyor connecting device of the present invention is provided between a conveyor device that conveys a conveyed product on the upper surface of a conveying chain or belt and another conveying device adjacent to the end of the conveyor device, and conveys between them. In a conveyor transfer device having transfer rollers for transferring an object, the transfer roller can be driven to smoothly transfer the transfer object to another transfer device on the downstream side.

By being driven in the direction, a material having good cushioning properties can be used for the drive transmission roller, and even if the conveyor device becomes a polygonal shape when rotating a chain or the like, it absorbs shock and vibration. And the transport roller can be driven smoothly.

  Moreover, in addition to the effect which the conveyor connecting apparatus which concerns on Claim 1 has the effect which the conveyor connecting apparatus of the invention which concerns on this claim 3 shows, the said roller for conveyance is a stepped shaft by which the large diameter part was provided in the edge part. When the transfer roller receives an external force, it is loosely fitted so that the large-diameter portion of the stepped shaft comes into contact with the drive transmission roller and is driven in the transfer direction by friction transmission. Since the fitted transfer roller can stop rotating by sliding with respect to the stepped shaft, the transfer roller of the transfer roller can be stopped when it is applied to an accumulation type transfer device to stop the transfer object. The rotation stops and the transported object is not damaged.

  Moreover, in addition to the effect which the conveyor transfer apparatus which concerns on any one of Claim 1 thru | or 3 show | plays the conveyor transfer apparatus of the invention which concerns on this invention 4, while the said roller for conveyance is provided in 3 or more rows, The conveyance roller that is not driven by the drive transmission roller is driven in the conveyance direction from the conveyance roller driven by the drive transmission roller via the drive transmission belt, thereby increasing the conveyance distance of the conveyor connecting device. Therefore, even if the distance to the downstream transfer device to be connected is long, it can be stably transferred.

  In the conveyor connecting apparatus according to the present invention, the conveying rollers are provided in at least two rows, and are driven in the conveying direction by drive transmission rollers provided on the lower surface side of the conveying rollers. It is driven in contact with the rotating part of the conveyor transport surface of the part, and the transport roller is driven with a simple structure, so that the transported product can smoothly ride on the other transport device on the downstream side at the transfer part of the conveyor. Any specific embodiment may be used as long as the effect of shifting is exhibited.

  That is, the conveyor transfer device of the present invention may be used when connecting between two conveyors in a straight line or when connecting at a right angle, and the transfer device other than the conveyor from the conveyor, the storage device It may also be used when connecting to the same.

  In addition, the conveyor in which the conveyor connecting device of the present invention is used may be any type of conveyor such as a belt conveyor or a chain conveyor as long as at least a portion of the conveying surface that contacts the drive transmission roller moves. .

  The specific material of the transport roller used in the present invention may be any material that is normally used in a transport device depending on the transport object and the purpose of transport.

  In addition, the drive transmission roller used in the present invention may be any material that can transmit a driving force by contact, and a chain conveyor in which a large number of chain links each having a flat top plate are connected by connection pins.
