Description

TECHNICAL FIELD

[0001] The utility model relates to a rail changing device, in particular to a rail changing device of a double-rail carrier. BACKGROUND

[0002] The pipeline is used for preparing products with multiple processing procedures, and when preparing, the product components are carried and delivered by carriers, and the carriers carry the components to move on the pipeline, so that each procedure of the product is completed in turn. According to different properties of the product components, the required carrier structure is generally different. For example, some components of footwear products are relatively small and scattered, and have relatively large hardness, and are not suitable for being delivered by clamping. For the carrying of these components, a wheel type tray type carrier can be used. In order to adapt to the stable walking of the carrier, a double-rail track can be used to support the carrier. The walking wheels on the carrier are supported on the track, and the carrier moves on the track under the drive of the driving mechanism. The track includes a main track and a branch track. The main track and the branch track are respectively composed of two parallel main rails and two parallel branch rails. The branch track forms a work station, and the main track connects each branch track together. Each work station forms a processing position, so that one or more processing procedures can be completed at the processing position. After the corresponding procedure is completed at the work station, the carrier moves to the downstream side. A rail changing device is arranged between the branch track and the main track to adapt to the rail changing of the carrier between the main track and the branch track. The structure of the rail changing device at the outlet end of the branch track includes a swing head. One end of the swing head is pivotally connected to the outlet end of the inner side branch rail, and the other end is used to be connected to the inner side main rail, so as to build a passage between the inner side main rail and the inner side branch rail for the inner side walking wheels on the carrier to support and move. The outer side branch rail and the outer side main rail are connected together through a curved connecting part. When the swing head is in the direction of the outer side main rail, the gap between the outer side main rail forms a passage for the other carriers to pass through the gap position on the main track.

[0003] The swing head is generally driven to rotate by a power mechanism. Since the swing head is relatively long, when the power mechanism is a cylinder, the other end of the swing head may not be able to timely abut against and connect to the inner side main rail when the working air pressure is insufficient. In addition, when the power mechanism is an electric motor, the electric motor may not be able to timely rotate the swing head to the position due to working errors. Due to the weight of the carrier and the carried objects, if the other end of the swing head is not in place, the carrying capacity of the swing head will be greatly affected, the other end of the swing head will sink severely, which may damage the swing head and affect the smooth rail changing of the carrier. UTILITY MODEL CONTENTS

[0004] The utility model needs to solve the technical problem: to provide a double-rail carrier rail changing device, which can effectively promote the other end of the swing head to timely abut against and connect to the inner side main rail, so as to smoothly change the rail of the carrier.

[0005] To solve the technical problem, the utility model discloses a technical scheme of a double-track carrier rail changing device, which is arranged between a main track and a branch track of a workstation. The main track comprises two parallel main rails, the inner main rail is continuously arranged, and the outer main rail is formed with a break at the inlet end and the outlet end of the workstation. The branch track comprises two parallel branch rails, and a channel is formed between the two branch rails for the carrier to pass through. The outer branch rail and the outer main rail are connected together through a curved connecting part. The rail changing device comprises a swing head arranged at the outlet end of the workstation. One end of the swing head is pivotally connected to the outlet end of the inner branch rail, and the other end is used for lapping onto the inner main rail. The rail changing device is characterized in that a pushing member is arranged at one end of the swing head. The pushing member extends into the channel from the outer side. The pushing member is used for receiving the abutment of the carrier to make the other end of the swing head lap onto the inner main rail before the carrier is completely supported on the swing head, so that the carrier can smoothly change the track.

[0006] The pushing member has a certain hardness. Before the carrier advances and changes the track, the pushing member is abutted by the carrier. Through the setting of the shape and the setting position of the pushing member, the other end of the swing head can be stably kept lapped together with the inner main rail before the carrier is completely supported on the swing head, so that the carrier can smoothly change the track.

[0007] Further, in the advancing direction of the carrier on the branch track, the outer end of the pushing member is located on the downstream side of the inner end. The pushing member can be a convex arc shape protruding outward or can be arranged obliquely, which makes the pushing member well adapt to the advancing direction of the carrier, so that the carrier smoothly passes through and pushes the pushing member.

[0008] Further, the carrier is provided with a limiting wheel. The limiting wheel is used for contacting the side surface of the branch rail. The pushing member extends into the running track of the limiting wheel, and the limiting wheel is used for abutting against the pushing member. The setting of the limiting wheel makes the running stability of the carrier on the track good, and through the action of the limiting wheel and the pushing member, the action between the carrier and the pushing member is smooth.

[0009] Further, the width of one end of the swing head is greater than the width of the other end. The inner side surface of the swing head is a plane, and the outer side surface of the swing head is an arc surface. This well adapts to the advancing direction of the carrier, so that the swing head can well adapt to the support requirement of the carrier on the basis of ensuring the smooth track changing of the carrier.

[0010] Further, a fixed plate is fixedly connected to the outlet end of the inner branch rail. One end of the swing head is pivotally connected to the fixed plate, and the trend of the outer side surface of the fixed plate adapts to the trend of the outer side surface of the swing head. Through the setting of the fixed plate, a larger support area can be provided for the carrier on the basis of ensuring the connection of the swing head.

[0011] Further, the other end of the swing head is provided with an elastic head, and the outer side of the elastic head is used to abut against the side of the inner main rail. The elastic head is generally made of soft plastic or rubber, and can abut against the main rail well to reduce the abrasion of the main rail.

[0012] Further, the other end of the swing head is provided with an installation port, and the cross section of the installation port is L-shaped. The elastic head is installed in the installation port, and the elastic head is used to abut against the side of the installation port. Through the installation port, the elastic head can be installed conveniently, and the position stability of the elastic head on the swing head is good.

[0013] Compared with the prior art, the utility model has the beneficial effects that: through the pusher arranged on the swing head, the carrier can abut against the pusher before the track change, the other end of the swing head can abut against the inner main rail, the swing head has good position stability when the swing head bears the carrier completely, and the swing head can provide good supporting force for the carrier. On one hand, the carrier can change the track smoothly, and on the other hand, the swing head is not damaged. Through the pusher, the use problem caused by the unstable work of the power mechanism driving the swing head to move can be solved effectively, and the work demand of the normal and smooth track change of the carrier can be met well.
