Abstract
Description
The present invention relates to a pallet conveying plant.
Various proposals have been made and implemented regarding the conveying equipment of a workpiece conveyance pallet, for example, from the viewpoint of conveyance efficiency and space saving with respect to conveying facilities of conveyance pallets, such as a vehicle body or a vehicle body part, as follows. Transfer equipment has been proposed.
For example, Japanese Patent Application Laid-Open No. 2006-44810 (Patent Document 1) conveys a pallet for loading and conveying automobile glass as a work in a horizontally mounted state for the purpose of saving space in a return line. A pallet conveying line is disclosed which has a conveying line, and a return line for supporting and returning the pallet in a vertically mounted state from the end of the conveying line toward the start end.
In addition, Japanese Patent Application Laid-Open No. 9-142643 (Patent Document 2) discloses a split pallet for loading left and right wheels, respectively, in a storage facility of a car that primarily stores a plurality of cars between transport lines of different types. It is disclosed that the transport space or the storage space can be miniaturized by transporting the car and keeping the divided pallets closer to each other when the car is not loaded, that is, when the empty pallet is transported and stored.
In this way, when the conveying equipment of the work conveying pallet is mounted and used in the work manufacturing line (including the assembly, storage, and inspection line), it is common that any equipment (processing equipment, etc.) is installed on both sides of the work conveying line. . Therefore, it is necessary to leave the space and working space for installing these facilities as much as possible on both sides or the periphery of a conveyance line.
However, in the case of the transfer lines disclosed in
In view of the above circumstances, in the present invention, it is a technical problem to secure a work space for a work and an installation space for a work required for work by achieving space saving of a pallet conveying equipment.
Solution to the above technical problem is achieved by the pallet transport facility according to the present invention. That is, this pallet conveyance apparatus is a pallet conveyance apparatus provided with the conveyance line which conveys the pallet of the state which loaded the workpiece, and the return line which returns an empty pallet from the end of a conveyance line to the beginning, WHEREIN: Two conveyance lines are side by side Pallets divided into left and right are arranged on each conveying line, and a return line is provided between a pair of conveying lines, and both divided pallets are conveyed on a pair of conveying lines, respectively, and each division It is characterized in that the pallet is returned on the return line. In addition, right and left here shall refer to the direction orthogonal to these conveyance and return directions, when carrying or return directions are carried forward and backward.
According to this structure, since each divided pallet is returned through the center side of a conveyance installation rather than conveyance, the space for a return line can be accommodated in the space for a conveyance line. For this reason, the pallet conveyance line can be reduced significantly by making the increment space as much as a return line substantially zero. Moreover, since sufficient space is secured on the side of the conveying line, it is possible to arrange a suitable work work facility without being limited in space along the conveying line of the work.
Here, the following conveying forms can be taken for the divided pallets. That is, one divided pallet is driven, and the other divided pallet is integrated with the divided pallet on the driving side through the work, and at the time of return, both divided pallets are integrated on each other and returned on the return line. .
According to this configuration, the driven pallet is transported integrally with the driven pallet at the time of return, and the driven pallet is driven only by returning the driven pallet. Is returned. As a result, the space can be further reduced, and even when the pallet is divided, the power required for the pallet transfer can be minimized, and the installation space of the drive mechanism can be reduced.
Of course, the conveyance form of a split pallet is not limited to the said form. For example, a pair of divided pallets conveyed at the end of side-by-side conveying lines may be alternately conveyed and returned on one return line. Alternatively, two return lines may be used, and each divided pallet may be returned on two return lines provided between the pair of transport lines. When the workpiece is used as the vehicle body, the space between the conveying lines (the spacing of the splitting pallets) is approximately the same as the width of the vehicle body, so that space for two return lines can be secured.
Moreover, you may comprise so that the division pallet conveyed on a conveyance line and the division pallet returned on a return line may be on the same plane.
Regardless of the time of conveyance and return, if the divided pallet is always on the same plane, the conveying equipment is simplified because the pallet can be transferred from the conveying line to the return line only by conveying in the pallet horizontal direction (vehicle width direction). Moreover, since it is enough to just move the minimum distance, it is also preferable at the point of conveyance efficiency. In addition, since the vertical direction of the pallet is always constant at the time of conveying the pallet, the vertical direction of the workpiece loaded on the pallet is also easy and accurate.
In addition, when paying attention to the pallet for workpiece conveyance, the configuration shown below aims at further space saving of the pallet conveying equipment, or reduces the proportion of the mechanism driving the pallet to the conveying equipment, thereby improving the space of the work equipment. It is also possible to aim for an increase.
That is, the pallet conveying apparatus which concerns on this invention has a power transmission part for receiving the power to a conveyance direction from the drive mechanism provided by one of the division pallets of a pair of division pallets provided separately from one division pallet, and the other division pallet The silver workpiece may be configured to be conveyed integrally with one divided pallet via the workpiece.
According to this structure, the structure around the pallet loading part in a conveyance installation can be simplified. In particular, since the drive mechanism is sufficient to be provided only on one pallet side, the installation space of the drive mechanism can be greatly reduced, and further space saving of the pallet transfer facility can be achieved. In addition, the space around the split pallet can be emptied as long as the entire transport equipment can be maintained. Therefore, access to the workpiece mounted on the divided pallet is also good, and workability is improved.
Here, as a specific form of a pair of dividing pallets, for example, a dividing pallet having a base having a work loading surface together and a side wall portion extending downward from the side edges of the base, wherein the work is divided into a pair of the side walls. The fitting parts for making the side wall parts adhere to each other in close contact with each other in the state mounted on the pallet are mentioned, respectively.
According to the above structure, the pallet divided to the left and right can be returned in an integrated state, so that even when the workpiece is not loaded on the pallet at the time of return, the pallet is driven on the driving side as in the case of conveyance by driving the driving side pallet integrated with the driven side pallet. Both divided pallets can be returned only by the drive mechanism provided. Moreover, since the side wall parts of the pallet divided left and right can be contacted and fitted, the pallet transfer mechanism required at the time of integration is also simple.
In this case, it is preferable that the contact area with the conveying side member in which this divided pallet is mounted among the lower surfaces of the at least one divided pallet forms the shape which can be slid with respect to a conveyance side member not only in a conveyance direction but a direction orthogonal to a conveyance direction. . By setting it as such a structure, the at least one division | segment pallet may be slid off from a conveyance member only by the movement of the division pallet in the horizontal direction, and the division pallets may be closely fitted. Therefore, the pallet conveyance mechanism required at the time of integration can be simplified more.
Moreover, when paying attention to the drive apparatus of the workpiece conveyance pallet, by setting it as the structure shown below, it is also possible to aim at further space saving of a pallet conveyance installation, and to increase the space for work equipment.
That is, the pallet conveying apparatus according to the present invention further includes a pallet driving device which is mounted and used on a pallet conveying line having a conveying line and a return line, and the pallet driving device is installed between the conveying line and the return line parallel to each other, The roller may be configured to have a plurality of rollers connected to the driving source, one side of the roller contacting the side face of the pallet on the conveying line, and the other side of the roller contacting the side face of the pallet on the return line.
When the pallet drive device is provided in this manner, the drive device is configured to be capable of conveying and returning the pallet by bringing the pallet side into contact with the side surfaces of different rollers at the time of conveyance and at the time of return. Since the conveying direction of a pallet is reversed in a parallel conveyance line and a return line, the pallet transfers the conveyance direction to a pallet by rotating the roller by contacting the side surface of the pallet on a conveyance line to one side of a roller. In addition, by moving the side of the pallet on the return line to the other side of the roller and rotating the roller in the same direction as the conveyance, the pallet is given a moving force in the return direction. Therefore, the drive device for conveyance can be combined with the drive device for return, and the installation space of such a drive device can be made small, and further miniaturization of a pallet conveyance installation can be attained. Moreover, since it is not necessary to provide each drive apparatus for return and conveyance, the cost down can be aimed at by that much.
In addition, since the direction of rotation of the roller can always be in one direction, it is not necessary to interpose a mechanism for changing the direction of the driving force applied to the pallet between the pallet and the roller on the return line. Therefore, even when it returns only by the drive apparatus (roller) for conveyance, the driving force of a return direction can be given to a pallet.
Here, as a specific configuration for achieving the contact state between the roller and the pallet, for example, further comprises a roller moving means for moving the roller between a position in contact with the pallet on the conveying line and a position in contact with the pallet on the return line. A constitution provided is considered. According to this structure, a relatively small roller can be adopted, and sufficient working space can be ensured between a conveyance line and a return line.
Moreover, as a structure of that excepting the above, the structure which provides the roller of the magnitude | size which a contact state with the pallet on a conveyance line and the contact state with the pallet on a return line is obtained, for example is considered. That is, by providing the roller of the said size in consideration of the space | interval of a conveyance line and a return line, the pallet can be provided with the driving force required for conveyance and return of a pallet, without providing a roller moving means etc.
