Description

  The present invention relates to a conveyor facility in which a roller group is rotatably arranged on a conveyor frame to form a conveyance path having a linear path portion and a curved path portion.

Conventionally, the following configuration is provided as this type. That is, the rollers of the straight roller conveyor and the curved roller conveyor are rotatably provided on the support frame via the support shaft, and the belt that is driven to circulate between the pulleys by the motor is used as a roller (or a pulley integrated with the roller). The load placed on the roller is moved along the rotation direction of the roller by abutting from below and rotationally driving the roller group. In this case, as the belt, a resin V belt having a reverse trapezoidal belt cross section or a resin V belt having a hexagonal cross section with both upper corners cut off is used (see, for example, Patent Document 1).

  However, according to the above-described conventional configuration, the upper surface portion of the belt is in contact with the roller (or pulley integrated with the roller) and the lower surface portion is supported by the pressure roller group, and therefore the upper and lower surfaces are Since each part is in contact with another object, damage due to wear becomes severe, and there is a possibility of adversely affecting the intended rotational force transmission. In addition, by providing the pressure rollers at a large number of locations, the structure becomes complicated and expensive.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a conveyor facility that can reduce damage due to wear and that can make the structure simple and inexpensive.

  In order to achieve the above-mentioned object, the conveyor equipment according to claim 1 of the present invention has a linear path portion and a curved path portion by disposing a group of rollers in a freely rotating manner on the conveyor frame. The roller group drive means arranges an endless chain common to each path portion along the transport path, with its forward and backward portions facing each other in the vertical direction. In addition, the endless chain is configured by providing a drive unit for the endless chain, and the endless chain slides one of the chain links paired in the conveyor width direction with respect to the link pin in the link length direction. It is configured to be movable, and the forward portion is configured to be movable below the roller group by the support guide by the guide member. It is obtained by, characterized in that at least a portion abuts from below rollers in a state that fits in the chain width friction member is provided.

  Therefore, according to the first aspect of the present invention, the object to be conveyed supplied to the starting end portion of the conveyance path can be conveyed linearly on the linear path part, and subsequently can be conveyed in a curved line on the curved path part. . At that time, in both path portions, a common endless chain in the driving means is rotated to obtain a conveying force. In other words, the endless chain that is being rotated can abut the integrated friction member from below on the roller group by the chain link being supported and guided by the guide member in the forward portion, and thus the rotational force of the endless chain Thus, the roller group is driven to rotate at a predetermined rotational speed. Thereby, in both path | route parts, a to-be-conveyed object can be continuously conveyed by the same conveyance speed. At that time, the reaction force of the contact (pressure contact) of the friction member can be stably received by the chain link because at least a part of the friction member is accommodated in the chain width.

  In the forward portion of the curved path portion, the end surface of the chain link slides in the link length direction with respect to the link pin by guiding the outer surface of the chain link in sliding contact with the guide member. The length is adjusted by moving it, and it does not swing unexpectedly in the chain width direction, so that it can always move smoothly in an arc along the curved path. Therefore, the friction member integrated on the endless chain side does not swing, and the roller group can be stably in contact from below.

  Furthermore, the friction member is divided and provided in units of chain links, so that the bending portion in the plan view of the friction member hardly occurs in the forward portion of the curved path portion due to the arc-like bending. The elastic contact from the lower side to the roller group can be performed. In addition, the endless chain can reduce damage due to wear by bringing only the contact surface of the friction member into contact with the roller group over the entire length of the conveyance path including the linear path portion and the curved path portion.

For example, the container A supplied to the starting end portion of the transport path 2 by the carrying-in means (not shown) is transported linearly on the straight path portion 2A by the linear conveyor device 11, and subsequently the curved conveyor device 21. Then, after being transported in a semicircular shape on the curved path portion 2B, it can be discharged from the end portion of the transport path 2 by unloading means (not shown). At that time, the conveyor devices 11 and 21 rotate the driving wheel body 45 by driving the motor 43 in the common driving means 30 to rotate the endless chain 31 to obtain the conveying force. That is, as shown in FIGS. 2 and 4, the endless chain 31 is reversely guided to the reversal ring body 40 at both end portions in the direction of the conveyance path 2, and the guide member 51 is in the forward portion 31 a between the reversal ring bodies 40.

By being supported and guided by the support surface 52 a, the contact surface 39 a of the integrated friction member 39 can be elastically contacted with the rollers 16 and 26 group from below, so that the roller 16 is driven by the rotational force of the endless chain 31. , 26 are driven and rotated around the roller shafts 17, 27 at a predetermined rotational speed. Thereby, in both the conveyor apparatuses 11 and 21, the container A can be continuously conveyed by the same conveyance speed. At this time, the reaction force of the elastic contact (pressure contact) of the friction member 39 is stabilized by the inner chain links 32B and 33B via the receiving member 36 because the friction member 39 is accommodated in the chain width 31W.

Thus, the endless chain 31 adjusts the length by sliding the inner chain link 33A on the outer side thereof in the link length direction with respect to the link pin 34, and does not swing unexpectedly in the chain width direction. Therefore, it is possible to move smoothly in an arc along the curved path portion 2B. Therefore, the friction member 39 integrated on the endless chain 31 side does not shake, and the elastic contact from the lower side of the contact surface 39a with the rollers 16 and 26 group can be stably performed. Thus, the transmission of the driving force by the endless chain 31 can always be suitably performed.

Further, the friction member 39 is provided by being divided in units of the chain links 32A, 32B, 33A, 33B, so that the friction member 39 is accompanied by an arcuate bend in the forward portion 31A of the curved path portion 2B. The roller 16 and 26 group can be elastically contacted from below with almost no bending deformation in a plan view, and therefore, the driving force can be transmitted smoothly and frictionally to the roller 16 and 26 group. This can be done with less damage to the member 39. Moreover, the endless chain 31 elastically abuts only the abutment surface 39a of the friction member 39 on the rollers 16 and 26 group over the entire length of the conveyance path 2 including the linear path portion 2A and the curved path portion 2B. Thus, damage due to wear can be reduced, and the guide member 51 can be provided with a simple and inexpensive structure due to the shape of the mold rail.
