Description

  The present invention relates to a slide drive device, and more particularly to a device that slide-drives in a state where two or more slide portions are synchronized by a single driving force generation source.

  2. Description of the Related Art Conventionally, a production line has been provided with a device in which a rod or the like is driven to slide for uses such as slide conveyance, positioning, and cutting of a workpiece. Specific slide drive devices include, for example, a device in which a plate is attached to the rod end of a pneumatic cylinder, or a linear guide or the like attached in parallel with the cylinder's rod expansion / contraction direction to ensure parallelism. There is. With regard to the slide drive device, a technique has been proposed in which the workpiece conveying rod is smoothly slid using the elastic force of a spring (Patent Document 1).

By the way, when sliding a wide workpiece such as a plate glass, it is necessary to apply a force to a plurality of locations in the workpiece. As a device corresponding to this, it is possible to adopt a structure in which a wide plate parallel to the end of the workpiece is attached to the rod end of one cylinder, and a plurality of chucks, claw portions, etc. are joined thereto.
An apparatus having a structure in which a plurality of slide mechanisms are arranged in parallel is also conceivable in principle.
Japanese Patent Laid-Open No. 2004-200968

However, in a device having a structure in which a wide plate is attached to the rod end of the cylinder, the wider the workpiece, the corresponding plate width needs to be increased correspondingly, resulting in a larger device size and weight.
Further, in an apparatus having a structure in which a plurality of slide mechanisms are arranged in parallel, it is necessary to synchronize the slide drive of each slide mechanism. That is, when a plurality of slide mechanisms do not synchronize well, it is conceivable that the workpiece is inclined or the workpiece is damaged due to local stress applied to the workpiece.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a slide drive device in which a plurality of slide portions can be driven to slide in synchronization.

In order to achieve the above object, the present invention provides a first base block and a first slide and a second slide that are slidably attached to each of the intersecting portions while partially intersecting the base block. A slide drive device having a block has the following characteristics.
In the slide drive device according to the present invention, the base block is provided with an action point that can reciprocate substantially linearly and a driving force generation source that reciprocates the action point. In the slide drive device according to the present invention, the first slide block has first and second portions facing each other across the intersection with the base block in the slide direction, and the second slide The block has third and fourth locations facing each other across the intersection with the base block in the sliding direction.

  Note that the term “substantially linear” in the above is basically the same as “linearly”, but “substantially straight” is considered in consideration of the looseness that occurs when taking into account the accuracy and crossing of the dimensions of the equipment. "Is added. In addition, the “driving force generation source” in the above refers to, for example, a pneumatic cylinder, a hydraulic cylinder, and a motor or a rotary actuator having a function of converting into linear motion (for example, screws such as a ball screw).

  Further, in the slide drive device according to the present invention, the first to the fourth portions which are linear bodies and bendable between the first to fourth portions and the action points of the base block. Each of the four transmission members is stretched. When the action point moves in one direction, a tensile force acts on the first and third transmission members, or the second and fourth transmission members, and the first and second forces are applied by the acting tensile force. The slide block slides. Here, the first and second slide blocks slide with an amount of displacement corresponding to the amount of movement of the action point.

  In the slide drive device according to the present invention having the above-described configuration, the first transmission member is between the action point and the first location, and the second transmission member is between the action point and the second location. The third transmission member is stretched between the action point and the third location, and the fourth transmission member is stretched between the action point and the fourth location. Then, the first slide block and the second slide block slide with a displacement amount corresponding to the movement amount of the action point. The “slide” here means a slide relative to the base block.

  In the slide drive device according to the present invention, by using the first to fourth transmission members, the first slide block and the second slide block are slid in a synchronized state with a simpler configuration than the above prior art. be able to. Further, in the slide drive device according to the present invention, since the first to fourth transmission members are linear bodies and members having flexibility are employed, the design relating to the handling of the transmission members is adopted. Is relatively easy. That is, if a gear, a shaft, a cam, or the like is used to transmit the driving force, a space must be secured for the arrangement, resulting in a low degree of design freedom. On the other hand, when the transmission member is used as in the slide drive device according to the present invention, the degree of freedom in designing the device can be increased.

In the slide drive device according to the present invention, the first slide block and the second slide block do not necessarily slide in the same direction. For example, one slide block is normal with respect to the base block. When projecting in the direction, it is possible to adopt a configuration in which the other slide block projects in the negative direction in synchronization with this.

For these reasons, when a hydraulic cylinder, a pneumatic cylinder, or the like is used as a driving force generation source, it is advantageous from the viewpoint of space and cost compared to the case of using the motor or the like.

Furthermore, a hydraulic cylinder or a pneumatic cylinder can generate a larger force than a motor having substantially the same volume, and is advantageous from the viewpoint of moving speed.
(Variation 2) In the slide drive device according to the present invention, wires are used as the first to fourth transmission members, and the first to fourth transmission members are located at the first to fourth locations. The pulleys are stretched between pulleys and action points via pulleys, and each pulley is pivotally supported by a base block.

  In the slide drive device according to this variation, a wire is used as the transmission member. For this reason, compared with the case where a chain etc. are used as a transmission member, size reduction and weight reduction of an apparatus can be achieved. That is, when a chain is used as the transmission member, the weight per unit length of the chain itself is heavier than that of the wire, and it is necessary to use a chain tensioner or the like. Become. Therefore, the slide drive device according to this variation is more advantageous from the viewpoint of device size and weight.

In this variation in which a wire is used as the transmission member, the elastic range of the wire can be used, so that the impact on the workpiece can be reduced.
(Variation 3) In the slide drive device according to the present invention, each of the first and second slide blocks is provided with a linear guide rail, and each of the first and second slide blocks in the base block. The linear guide rail is supported by the linear guide provided at the intersection.

(Variation 4) The slide drive device according to the present invention further includes third and fourth slide blocks that partially cross the base block and are slidably attached at the intersecting portions. The base block has third and fourth slide guide portions corresponding to the third and fourth slide blocks, respectively.
In the slide drive device according to this variation, in the slide direction of each slide block, the first slide block has the fifth and sixth locations facing each other across the intersection with the base block, and the second slide The block has seventh and eighth locations facing each other across the intersection with the base block, and the third slide block includes ninth and tenth locations facing each other across the intersection with the base block. The fourth slide block has eleventh and twelfth locations facing each other across the intersection with the base block.

  Moreover, in the slide drive device according to this variation, between the fifth place and the ninth place, between the sixth place and the tenth place, and between the seventh place and the eleventh place. , And between the eighth portion and the twelfth portion, fifth to eighth transmission members, which are linear bodies and have flexibility, are respectively stretched. The third and fourth slide blocks are characterized by following the first and second slide blocks.

In the slide drive device according to this variation, the third and fourth slide blocks slide in a state of being synchronized with the first and second slide blocks. That is, in the slide drive device according to this variation, the four slide blocks slide in a synchronized state.
(Variation 5) In the slide drive device according to Variation 4, the first to fourth slide blocks are arranged such that each slide axis is two-dimensionally arranged in a virtual plane that is assumed to intersect each slide axis. It has a relationship.

(Variation 6) In the slide drive device according to the present invention, the moving axis of the action point and the slide axes of the first and second slide blocks are set in a substantially parallel state. . Here, “substantially” of “substantially parallel” is interpreted in the same manner as “substantially” of “substantially linear”.
(Variation 7) The slide drive device according to Variation 6 is characterized in that the first slide block and the second slide block are set in a state in which the slide shafts are on the same line. To do.
