The present invention relates to an automatic pitch feed apparatus, and more particularly, to an automatic pitch feed apparatus capable of positioning a pallet in the next working position with minimal movement without an additional alignment device.

Various types of transfer devices are used. A representative example of such a conveying device is a conveyor belt. A conveyor belt is a device which transfers a specific article by installing several support rollers and drive rollers in a guide, and installing and driving a belt along this roller. Such a conveyor belt may be used for loading and unloading loads, but may be used in a process of a production line, and may be used to move goods in the process to the next process.

However, such a conveyor belt is difficult to select the exact position of the goods to be conveyed, and there is a drawback that is difficult to put in the operation of repeated stopping and conveying. That is, the conveyor belt is easy to use where continuous movement is required, but there are some difficulties to apply to the production process. Therefore, in the case of using a conveyor belt, additional devices are used to stop the conveyed article at a desired position or to put it in a desired process.

Apparatuses similar to the conveyor belt introduced have been used to solve this problem of the conveyor belt. A representative example is a conveying system using pallets. A conveying system using a pallet is a device for conveying an article on a pallet to a designated place by a driving device while the pallet for conveying the article moves along a pre-installed guide.

In addition, Figure 3 is an exemplary view schematically showing the cross-sectional shape of the automatic pitch feed device. However, Figure 3 is shown to help understand the cross-sectional shape does not show the exact cut plane, other drawings also briefly shown only the parts necessary for the understanding of the description.

1 to 3, the automatic pitch transfer device according to the present invention includes a pallet 110, a pallet guide 120, a first transfer cylinder 130, a second transfer cylinder 150, and a latch unit 140. And a centering unit 160. Here, in describing the present invention, a control device for adjusting the automatic pitch feeder will be omitted and described.

Pallet 110 is a plate in the form of a plastic or metal provided to transport the article. The pallet 100 is seated on the pallet guide 120 and is moved on the pallet guide 120 by the first transfer cylinder 130 or the second transfer cylinder 150. One or more pallets 110 are formed such that the pinholes 111 to which the centering pins 161 of the centering unit 160 are coupled penetrate the surface direction so that the articles are aligned at a specific position during transportation. That is, when the pallet 110 is moved to a predetermined pitch by the transfer cylinders 130 and 150, the centering pin 161 is coupled to the pinhole 111 to temporarily fix the pallet 110. In addition, the lower surface 116 of the pallet 110, the latch groove 115 is formed substantially parallel to the pallet guide 120. The latch groove 115 is provided to cause the cross section and the latch of the latch 141 when the latch 141 is raised. That is, when the latch 141 is positioned below the latch groove 115, the cross-section 145 of the latch 141 rises toward the latch groove 115 by the spring 143 coupled to the latch 141. Done. As a result, the end surface 146 of the end portion 145 of the latch 141 contacts the latch groove 115 to generate a latch. At this time, the pallet 110 is transferred by the force applied to the latch 141 by the transfer cylinders 130 and 150. Thereafter, when the transfer is completed, the latch 141 is returned by the transfer cylinders 130 and 150, and the pallet 110 is fixed by the centering pin 161 at the transfer position. Therefore, the lay groove 115 is formed in the form of a pair with the latch 141, when the latch 141 is moved in the conveying direction of the pallet 110 is caught between the pallet 110 and the latch 141. It may be formed in any form as long as it is a form to generate.

The pallet guide 120 has a pallet 110 seated thereon, and secures a path for the movement of the pallet 110. In particular, the pallet guide 120 is formed such that the bent surface 112 on which the pallet 110 is seated has a 'c' shape. This allows the pallet 110 to move smoothly in the conveying direction, and the pallet 110 is separated from the pallet guide 120 when the centering pin 161 is coupled and detached or when the latch 141 is caught or pressed. This is to prevent. In addition, the center of the pallet guide 120, the centering unit 160 and the transfer cylinders (130, 150) are installed to achieve the fixing and movement of the pallet (110).

The first transfer cylinder 130 moves the latch unit 140 in the moving direction of the pallet 110 or in the opposite direction to move the pallet 110 on the pallet guide 120. To this end, the first transfer cylinder 130 includes a first cylinder 131, a first cylinder arm 133, and a first cylinder hook 135. The first cylinder 130 generates pressure to operate the first cylinder arm 133 in a horizontal direction (hereinafter, the horizontal direction is assumed to be 'a moving direction of the pallet or the opposite direction'). Through this, the first cylinder 130 moves the latch unit 140 coupled with the first cylinder hook 135 and the first cylinder hook 135 in the horizontal direction. The first cylinder arm 133 transmits the force from the first cylinder 130 to the first cylinder hook 135 to start the first cylinder hook 135 in the horizontal direction. The first cylinder hook 135 is coupled to the end of the first cylinder arm 133 and the latch unit 140 to apply the force from the first cylinder 131 and the first cylinder arm 133 to the latch unit 140. To pass.

Like the first transfer cylinder 130, the second transfer cylinder 150 moves the latch unit 140 in the horizontal direction. The second transfer cylinder 150 also includes a second cylinder 151, a second cylinder 153, and a second cylinder hook 155. This may be understood with reference to the first transfer cylinder 130, and a detailed description thereof will be omitted. In the detailed description of the present invention, a case in which both the first transfer cylinder 130 and the second transfer cylinder 150 are provided will be described as a representative example. As such, when the first transfer cylinder 130 and the second transfer cylinder 150 are provided, the distance that the pallet 110 moves by the first transfer cylinder 130 and the second transfer cylinder 150 is different from each other. can do. That is, the first transfer cylinder 130 moves the pallet 110 only one pitch, that is, one unit distance, and the second transfer cylinder 150 moves the pallet by a distance corresponding to a pitch of two pitches or more. It is possible to move 110). Through this, it is possible to increase the efficiency and speed of the process by increasing the moving speed of the pallet (110). Alternatively, the first transfer cylinder 130 and the second transfer cylinder 150 may move the pallet 110 in different directions, but in this case, the latch unit 140 should be installed in accordance with the moving direction. do. However, this does not limit the present invention. In addition, the operation of the transfer cylinders 130 and 150 will be described in more detail with reference to FIG. 4.

The latch unit 140 moves the pallet 110 in the horizontal direction by the force from the transfer cylinders 130 and 150. For this purpose, the latch unit 140 includes a latch 141, a hinge 142, a spring 143, and a latch arm 144. The latch arm 144 is installed to be substantially horizontal with the pallet 110 around the pallet guide 120. The latch arm 144 is fixed to the latch 141 and the spring 143 at regular intervals. In addition, the latch arm 144 is coupled to the cylinder hooks 135 and 155 to reciprocate the latch 141 installed in the latch arm 144 in the horizontal direction. The latch arm 144 and the latch 141 are coupled by the hinge 142, and the latch 141 is maneuvered in the vertical direction with the hinge 142 as the axis. The latch 141 forms a hook with the pallet groove 115 of the pallet 110 to transfer the pallet 110 by the transfer cylinders 130 and 150. That is, when the transfer cylinders 130 and 150 move the latch 141 in the direction opposite to the pallet 110 moving direction, the latch 141 is pressed by the lower surface of the pallet 110 and the pallet is pressed. 110, the lower portion is moved. When the latch groove 115 is positioned on the upper portion of the latch 141 located on the lower surface of the other pallet 110 after the movement, the cross section of the latch 141 rises to the inside of the latch groove 115, and the pallet 110 moves. When the latch 141 is moved in the direction, a latch occurs between the cross section of the latch 141 and the latch groove 115. When the jam occurs, the pallet 110 is started in the conveying direction by the conveying cylinders 130 and 150. By repeating such a process, the pallet 110 is transferred horizontally on the pallet guide 120. That is, the latch 141 protrudes from the pallet groove 115 and repeats pressing on the pallet lower surface 116. The spring 143 provides a force that pushes the cross-section of the latch 141 upward from the bottom of the latch 141 so that the latch 141 protrudes into the pallet groove 115. This will be described in more detail with reference to FIG. 4. To this end, the latch 141 is formed to have a long length in one direction, one end is coupled to the latch arm 144 by a hinge 142, the spring 143 is coupled to the bottom surface of the other end side. The upper surface of the cross section of the latch 141 is formed with a slope so that easy pressing occurs by the pallet 110, and the end cross section of the cross section is formed to have a cross-sectional shape where the latch groove 115 is easily matched. do.

The centering unit 160 serves to fix and align the pallet 110. For this purpose, the centering unit 160 includes a centering pin 151, a centering bar 162, a centering bar guide shaft 163, a centering cylinder 165, and a guide housing 166. The center ring pin 151 is installed in the center ring bar 162 at regular intervals and moves in the vertical direction as the center ring bar 162 moves. The centering pin 151 is coupled to the pinhole 111 of the pallet 110 by rising in the vertical direction to fix or align the pallet 110 at a specific position, and when the pallet 110 moves, the pallet 110 is lowered. To move). A plurality of centering pins 151 are fixed to the centering bar 162 at regular intervals, and are coupled to the centering bar guide shaft 163 to raise the setter pins 151 in the vertical direction in accordance with the movement of the guide shaft 163. Or descend. The guide shaft 163a installed in the vertical direction is installed to penetrate the guide housing 166, and the guide shaft 163b installed in the horizontal direction is combined with the vertical guide shaft 163a and the centering cylinder 165 to guide the vertical direction. The shaft 163a is moved in the vertical direction. The centering cylinder 165 is installed in the same structure as the table 190, and the movable portion of the cylinder is coupled with the horizontal guide shaft 163b. The centering cylinder 165 is to raise or lower the centering pin 161 through the reciprocating motion of the cylinder to fix or release the pallet 110.
