Description

[Technical Field]

[0001] The present invention relates to a bolt arrangement device that arranges a plurality of bolts in one direction, and a bolt installation device using the same. [Background technology]

[0002] One example of the automobile manufacturing process is the installation of an inverter and a motor cable. In this inverter / motor cable installation process, for example, multiple bolts are tightened in one direction to fasten the inverter and the motor cable. In the past, workers would repeatedly pick up each bolt, insert it into a tool socket, and then tighten it. This required repeated insertion of the bolts into the socket and tightening the bolts for each bolt, which created a problem of time-consuming work.

[0003] Patent Document 1 describes a bolt supply device that supplies bolts one by one through piping to a socket, while Patent Document 2 describes a tightening tool that stores a plurality of bolts aligned vertically in a cassette, sends the bolts one by one from the cassette to a bolt holding mechanism, and fits them into a socket.

[0004] According to Patent Documents 1 and 2, it is possible to automatically load bolts into sockets, but to load multiple bolts into multiple sockets at the same time, a dedicated supply device is required for each socket, which poses the problem of making the device structure complex and expensive.

[0005] [Patent Document 1] Patent No. 4400828 [Patent Document 2] Patent No. 3939138 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made in light of the above-mentioned problems, and aims to provide a bolt placement device and a bolt installation device that have a simple configuration and can simultaneously install multiple bolts into multiple sockets. [Means for solving the problem]

[0007] The bolt placement device of the present invention places a plurality of bolts in a line in one direction, and includes a bolt supply means for supplying bolts one by one, a bolt placement section in which a plurality of bolt placement holes for individually placing bolts are arranged in a line in one direction, a movement means for moving the bolt placement section in one direction to make each bolt placement hole face the bolt supply means in order so that bolts supplied from the bolt supply means are placed in each bolt placement hole in order, and a movement control means for controlling the movement of the bolt placement section so that each bolt placement hole stops in order at a position facing the bolt supply means.

[0008] The bolt installation device of the present invention comprises the bolt arrangement device of the present invention and installation means having a plurality of sockets for individually installing a plurality of bolts arranged in the bolt arrangement section. [Effects of the Invention]

[0009] According to the present invention, the movement means moves the bolt placement section in one direction so that each bolt placement hole faces the bolt supply means in sequence, and the movement control means controls the movement of the bolt placement section so that each bolt placement hole stops in sequence at a position facing the bolt supply means, making it possible to easily arrange multiple bolts side by side in one direction. Therefore, with a simple configuration, multiple bolts can be simultaneously installed in multiple sockets.

[0010] In addition, the movement control means is arranged to work in conjunction with the bolt placement section and has a positioning section provided with a plurality of inserted sections extending in one direction individually corresponding to each bolt placement hole, and an insertion member that can be inserted into and removed from each inserted section in accordance with the movement of the bolt placement section, and when one bolt placement hole moves to a position opposite the bolt supply means, the insertion member is brought into contact with the end of one of the inserted sections to stop the movement of the bolt placement section, making it possible to more easily arrange a plurality of bolts in one direction with a simple configuration. [Brief explanation of the drawings]

[Figure 5] 2 shows the configuration of an attachment means for attaching a bolt placed in the bolt placement device shown in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0013] 1 to 4 show the configuration of a bolt positioning device 10 according to one embodiment of the present invention. Fig. 5 shows the configuration of an attachment means 20 that attaches a bolt M placed in the bolt positioning device 10.

[0014] The bolt placement device 10 places a plurality of bolts M lined up in one direction. The bolt placement device 10 includes a bolt supply means 11 that supplies the bolts M one by one, a bolt placement section 12 in which a plurality of bolt placement holes 12A are lined up in one direction and in which the bolts M are individually placed, a movement means 13 that moves the bolt placement section 12 in one direction, and a movement control means 14 that controls the movement of the bolt placement section 12. Note that the bolt supply means 11 and part of the movement control means 14 are omitted from Figures 3 and 4.

[0015] The bolt supply means 11 has, for example, a bolt supply pipe 11A that supplies bolts M one by one. The bolt supply pipe 11A is preferably sized to allow a single bolt M to pass through with the threaded portion leading, and is configured so that the bolt M is inserted from the insertion side and discharged from the discharge side.

[0016] The bolt placement section 12 is formed, for example, from a plate-like member, and has a plurality of bolt placement holes 12A formed in one direction at one end. The spacing and number of the bolt placement holes 12A can be set as desired depending on where the bolts M are to be placed. The spacing between the bolt placement holes 12A may be the same or different. Each bolt placement hole 12A is designed so that, for example, the threaded portion of a bolt M can be inserted and the head can be engaged to place the bolt.

[0017] The moving means 13 moves the bolt placement section 12 in one direction, and causes each bolt placement hole 12A to face the bolt supplying means 11 in order so that the bolts M supplied from the bolt supplying means 11 are placed in each bolt placement hole 12A in order. Specifically, for example, the moving means 13 moves each bolt placement hole 12A so that it faces the discharge side of the bolt supplying pipe 11A in order. The moving means 13 is, for example, a cylinder 13A such as an air cylinder and a bolt placement section and a guide member 13B such as a guide rail that guides the movement of the guide member 12. The guide member 13B extends in one direction, for example.

[0018] The movement control means 14 controls the movement of the bolt placement section 12 so that each bolt placement hole 12A stops in order at a position facing the bolt supply means 11. The movement control means 14 has, for example, a positioning section 14B provided with a plurality of inserted sections 14A, and an inserting member 14C that can be inserted into or removed from each inserted section 14A in accordance with the movement of the bolt placement section 12. The inserting member 14C can be moved in the vertical direction by a cylinder (not shown), such as an air cylinder, thereby allowing it to be inserted into or removed from each inserted section 14A.

[0019] The positioning portion 14B is formed of, for example, a plate-like member and is disposed so as to move in conjunction with the bolt placement portion 12. Specifically, the positioning portion 14B is coupled to, for example, a lateral side of the bolt placement portion 12 in one direction. Each inserted portion 14A is, for example, slit-shaped or groove-shaped and is provided extending in one direction so as to individually correspond to each bolt placement hole 12A. The movement control means 14 is configured to, for example, when one bolt placement hole 12A moves to a position facing the bolt supply means 11 (for example, the discharge side of the bolt supply pipe 11A), bring the inserting member 14C into contact with an end of one inserted portion 14A corresponding to that one bolt placement hole 12A, thereby stopping the movement of the bolt placement portion 12.

[0020] The inserted portions 14A are preferably arranged alternately in a first row and a second row in one direction according to the order of the corresponding bolt arrangement holes 12A. For example, the first inserted portion 14A corresponding to the first bolt arrangement hole 12A is preferably arranged in the first row, and the second inserted portion 14A corresponding to the second bolt arrangement hole 12A is preferably arranged in the second row. Furthermore, the inserting member 14C preferably has a first inserting member 14D arranged corresponding to the first row of the inserted portions 14A, and a second inserting member 14F arranged corresponding to the second row of the inserted portions 14A.

[0021] The terminal end of each inserted portion 14A in the movement direction of the bolt placement portion 12 is preferably provided to correspond to, for example, the corresponding bolt arrangement hole 12A. Specifically, the terminal end of each inserted portion 14A is preferably located on a line perpendicular to one direction passing through the corresponding bolt arrangement hole 12A. The starting end of each inserted portion 14A in the movement direction of the bolt placement portion 12 is preferably provided to correspond to, for example, the bolt arrangement hole 12A immediately preceding the corresponding bolt arrangement hole 12A. Specifically, the starting end of each inserted portion 14A is preferably located on a line perpendicular to one direction passing through the bolt arrangement hole 12A immediately preceding the corresponding bolt arrangement hole 12A. The starting end of the first inserted portion 14A in the movement direction of the bolt placement portion 12 can be set arbitrarily. Note that in FIGS. 3 and 4, the perpendicular to one direction passing through each bolt arrangement hole 12A is indicated by a dashed line.

[0022] With this configuration, for example, while the bolt placement portion 12 is stopped by the first insertion member 14D, the second insertion member 14F can be inserted into the inserted portion 14A, and while the bolt placement portion 12 is stopped by the second insertion member 14F, the first insertion member 14D can be inserted into the inserted portion 14A, making it possible to easily control the movement of the bolt placement portion 12. Note that Fig. 3 shows a state in which the first insertion member 14D is inserted into the first inserted portion 14 and abuts against the end portion to stop the bolt placement portion 12, and Fig. 4 shows a state in which the second insertion member 14F is inserted into the second inserted portion 14 and abuts against the end portion to stop the bolt placement portion 12.

[0023] The bolt positioning device 10 is preferably used, for example, as a bolt setting device in which a plurality of bolts M placed in the bolt positioning device 10 are simultaneously set by a setting means 20. The setting means 20 has, for example, a plurality of sockets 21 that individually set a plurality of bolts M placed in the bolt placement section 12. Each socket 21 is rotatable, for example, by a rotation mechanism (not shown). Each socket 21 is disposed, for example, on an arm 22 and is movable. The setting means 20 is disposed, for example, near the destination to which the bolt placement section 12 is moved.

[0024] The bolt placement device 10 operates, for example, as follows: First, for example, the first insertion member 14D is inserted into the first inserted portion 14A corresponding to the first bolt placement hole 12A, and the bolt placement portion 12 is moved in one direction by the moving means 13. When the first bolt placement hole 12A moves to a position corresponding to the discharge side of the bolt supply pipe 11A, the first insertion member 14D comes into contact with the terminal end of the first inserted portion 14A corresponding to the first bolt placement hole 12A, and the movement of the bolt placement portion 12 stops (see FIG. 3).

[0025] When the bolt placement section 12 stops, one bolt M is supplied to the first bolt placement hole 12A via the bolt supply pipe 11A. During this time, for example, a second insertion member 14F is inserted into the second inserted portion 14A corresponding to the second bolt placement hole 12A. After the bolt M has been supplied to the first bolt placement hole 12A and the second insertion member 14F has been inserted into the second inserted portion 13A, the first insertion member 14D is removed from the first inserted portion 13A. This releases the first insertion member 14D from stopping the movement of the bolt placement section 12, and movement of the bolt placement section 12 by the moving means 13 resumes.

[0026] Next, when the second bolt placement hole 12A moves to a position corresponding to the discharge side of the bolt supply pipe 11A, the second insertion member 14F abuts against the end portion of the second inserted portion 14A corresponding to the second bolt placement hole 12A, and the movement of the bolt placement portion 12 stops (see Figure 4).

[0027] When the bolt placement section 12 stops, one bolt M is supplied to the second bolt placement hole 12A via the bolt supply pipe 11A. During this time, for example, a first insertion member 14D is inserted into the third inserted portion 14A corresponding to the third bolt placement hole 12A. After the bolt M has been supplied to the second bolt placement hole 12A and the first insertion member 14D has been inserted into the third inserted portion 13A, the second insertion member 14F is removed from the second inserted portion 13A. This releases the stop on the movement of the bolt placement section 12 by the second insertion member 14F, and movement of the bolt placement section 12 by the moving means 13 resumes.

[0028] This process is repeated until the bolt M is supplied to the last bolt placement hole 12A. After that, the first insertion member 14D or the second insertion member 14F is removed from the last inserted portion 14A corresponding to the last bolt placement hole 12A. This releases the movement of the bolt placement section 12, and the bolt placement section 12 moves in one direction to a predetermined position.

[0029] After placing multiple bolts M in the bolt placement section 12, the arm 22 of the mounting means 20 is moved to mount each bolt M in each socket 21. At this time, it is preferable to rotate each socket 21 until the head of each bolt M is housed in each socket 21. This is because the head of each bolt M can be mounted without being tilted.

[0030] As described above, according to this embodiment, bolt placement section 12 is moved in one direction by movement means 13 so that each bolt placement hole 12A faces bolt supply means 11 in sequence, and movement control means 13 controls the movement of bolt placement section 12 so that each bolt placement hole 12A stops in sequence at a position facing bolt supply means 11, so that multiple bolts M can be easily arranged side by side in one direction. Therefore, multiple bolts M can be simultaneously attached to multiple sockets 21 with a simple configuration.

[0031] In addition, the movement control means 14 is arranged to work in conjunction with the bolt placement section 12 and has a positioning section 14B provided with a plurality of inserted sections 14A extending in one direction individually corresponding to each bolt placement hole 12A, and an insertion member 14C that can be inserted into and removed from each inserted section 14A in accordance with the movement of the bolt placement section 12.When one bolt placement hole 12A moves to a position opposite the bolt supply means 11, the insertion member 14C is brought into contact with the end of one inserted section 14A to stop the movement of the bolt placement section 12, thereby making it easier to arrange a plurality of bolts M in one direction with a simple configuration.

[0032] Although the present invention has been described above using embodiments, the present invention is not limited to the above embodiments and can be modified in various ways. For example, although each component has been specifically described in the above embodiments, the specific configuration of each component may be different. In addition, it is not necessary to include all of the above-described components, and other components may be included.

[0033] In addition, in the above embodiment, the inserted portions 14A are arranged alternately in a first row and a second row along one direction according to the order of the corresponding bolt arrangement holes 12A, and the insertion member 14C has a first insertion member 14D arranged corresponding to the first row of inserted portions 14A and a second insertion member 14F arranged corresponding to the second row of inserted portions 14A.However, it is also possible to provide each inserted portion 14A separately and arrange the insertion member 14C to correspond individually to each inserted portion 14A.

[0034] Furthermore, in the above embodiment, the first inserted portion 14A corresponding to the first bolt arrangement hole 12A is arranged in a first row, and the second inserted portion 14A corresponding to the second bolt arrangement hole 12A is arranged in a second row, and a first insertion member 14D is provided corresponding to the first row of inserted portions 14A, and a second insertion member 14F is provided corresponding to the second row of inserted portions 14A.However, the first and second rows may be reversed, and the first insertion member 14D and second insertion member 14F may be reversed.
