Description

[Detailed Description of the Invention] The present invention is based on a slat conveyor that supports and conveys automobiles, for example in an automobile manufacturing factory, that is, a pair of left and right roller chains, and a slat plate attached between opposing chain links of these roller chains. This relates to a slat conveyor.

The slat conveyor configured as described above intermittently transports automobiles with the wheels supported by the slat plates, and various operations are performed on the automobiles during the intermittently stopped periods. Therefore, if the wheel-receiving surface of the slat plate is flat, there may be a transfer error when transferring the car to the slat conveyor, a shock during intermittent conveyance, etc. This will result in misalignment, which will have a negative impact on various types of work, especially automated work. In order to solve this problem, it is conceivable to form a V-shaped recess on the upper surface of the slat plate and to fit the wheels into this recess. However, in this case, when the vehicle is taken out in the transport direction at the end of the transport path, it is not easy to take out the vehicle because the wheels fit into the recesses described above. Therefore, recently, the slat plate is cut out, a pair of rocking receiving plates are provided in this notch, and the wheel is fitted into the V-shaped receiving surface formed by the downward movement of these swinging receiving plates to perform positioning. Then, at the end of the conveyance path, a configuration has been considered in which cam rollers attached to the lower surfaces of both swing receiving plates act on the cam rail to move both swing receiving plates upward so that their upper surfaces become flat. There is. However, according to this configuration, since a notch is formed and a pair of rocking receiving plates are disposed in the notch, manufacturing is time-consuming and the structure is complicated. In addition, when the swinging receiving plate moves upward, the cam roller on the transport direction side first acts on the cam rail, so the swinging receiving plate on the transporting direction side moves upward first, and then the remaining swinging receiving plates follow. This will result in an upward movement. As a result of the upward movement being carried out in a deviated manner, the rocking receiving plate that moves upward in advance acts in an oblique direction with respect to the direction of the load on the wheel side, making it impossible to lift the wheel smoothly. There is a risk of damaging the wheels.

The purpose of this invention is to adopt a pair of swingable divided slat plates, but to
The object of the present invention is to provide a slat conveyor whose overall structure can be simplified and which can move both divided slat plates upward at the same time.

In order to achieve the above object, the slat conveyor of the present invention consists of a pair of left and right roller chains and slat plates attached between opposing chain links of these roller chains. These divided slat plates are each attached vertically swingably to the chain link side via pins perpendicular to the direction of movement, so that the opposing ends become free swinging ends. A stopper surface is formed on the chain link side to restrict the lower limit of movement of both divided slat plates so that the upper surface of the plate becomes a V-shaped receiving surface, and a bracket is attached to the lower surface of the free end of one of the divided slat plates, and a roller is attached to this bracket. A cam roller is attached via a shaft, a bracket placed on the roller shaft is connected from the lower surface of the free end of the other split slat plate, and a cam rail is provided at the end of the conveyance path to guide the cam roller upward. are doing.

According to the slat conveyor of the present invention having such a configuration, the following effects can be expected. That is, since a pair of divided slat plates are constructed by dividing a normal slat plate into two, manufacturing can be performed more easily and the structure can be simplified compared to a type in which notches are formed. Furthermore, when the cam roller rides on the cam rail at the end of the conveyance path, one of the divided slat plates moves upward via the bracket, and at the same time, the other divided slat plate also moves upward via the bracket on the roller shaft that is moving upward. Therefore, since both divided slat plates move upward at the same time, a pushing force can be applied from directly below in the direction of the load on the wheel side, and the wheel can be lifted smoothly. At the same time, it is possible to prevent damage to the wheels.

An embodiment of the present invention will be described below based on the drawings. A pair of left and right slat conveyors 1
basically consists of a pair of left and right guide rails 3 supported by a machine frame 2, and a pair of left and right roller chains 5 supported and guided by the guide rails 3 via rollers 4.
, a slat plate 7 attached between opposing chain links 6 of these roller chains 5, and an intermittent drive device (not shown) interlocked with the roller chain 5. The slat plate 7 at the appropriate position is divided into two in the direction of movement, forming two divided slat plates 7A and 7B. A support plate 8 is integrally connected inward from the chain link 6 corresponding to this divided portion, and a strip 9 is attached to the support plate 8. Both divided slat plates 7A and 7B are installed between a pair of left and right strips 9, and pins 10A and 10B are inserted perpendicularly to the moving direction so that the opposite ends thereof become swinging free ends 7a and 7b. They are each attached to the strip member 9 via the screws 9 so as to be able to swing up and down. The upper surface of the strip 9 is formed into a V-shaped stopper surface 11 when viewed from the side, and this stopper surface 11 receives the lower surfaces of the two divided slat plates 7A, 7B, thereby allowing the two divided slat plates 7A, 7B to The top surface of

A bracket 12 is connected downward from the lower surface of the free end of the pin 10.
A cam roller 14 is attached via a roller shaft 13 parallel to A and 10B. From the lower surface of the free end of the other divided slat plate 7B, the roller shaft 1

The action will be explained below.

Since there is no cam rail 17 in the portion of the transport path 16 other than the terminal end, both divided slat plates 7A and 7B are connected to pins 10A and 1 as shown in FIG.
It moves downward around 0B and is received by the stopper surface 11, so that the upper surface becomes a V-shaped receiving surface. In this state, the automobile 19 is transferred to the starting end of the transport path 16 using, for example, a suspended transport device. At this time, each wheel 20 is received by a V-shaped receiving surface, and even if there is a transfer error, the wheels 20 are automatically positioned at a fixed position. In this state, it is intermittently conveyed, and various operations are performed during the intermittently stopped periods. In addition, since each wheel 20 is supported by a V-shaped receiving surface, the impact on the vehicle 1 during intermittent conveyance is
Movement of 9 is blocked. At the end of the conveyance path 16, the cam roller 14 rides on the cam rail 17, and as a result, one of the divided slat plates 7A moves upwardly around the pin 10A via the bracket 12. At that time, the roller shaft 13 also rises, so

Move up around B. That is, both divided slat plates 7A and 7B move upward by the same amount at the same time, and as a result, a pushing force is applied from directly below to the load direction on the wheel 20 side, and the wheel 20 can be moved smoothly. The upward movement of both divided slat plates 7A and 7B is as follows:
This process is continued until the upper surface becomes flat as shown in FIGS. 4 and 5. Therefore, movement to the outside of the slat conveyor 1 via the transfer plate 18 can be performed smoothly.
