Since the direction is at right angles, the installation space for the entire system must be wide. In addition, the operator is forced to adopt a right-angled movement mode from the skewering device 6 to the packaging device through the take-out device 8, and the workability is lowered. In addition, the take-out device 8 needs to control the delivery of the four bar-shaped workpieces W to the conveyor device 5 using a detection sensor or a high-performance motor, and there is a problem that the construction is complicated and the construction cost is high.

  In addition, what is described in the said patent document 1 is known as what changes the direction of the horizontal direction of a workpiece | work similarly to the above-mentioned conventional workpiece | work transfer system. In the workpiece transfer system disclosed in this publication, the reversing device advances into the workpiece conveyance path while changing the workpiece in the horizontal direction while the workpiece is being conveyed by the feeding conveyor, and reverses the workpiece in the horizontal direction. Evacuate from. The work after reversal is sent to a downstream processing apparatus by a delivery conveyor. However, the workpiece transfer system disclosed in this publication must also change the horizontal orientation of the workpiece using the detection sensor and the high performance motor as described above.

  Other systems include a so-called L-shaped conveyor that gradually changes the horizontal direction while the workpiece is oriented with the workpiece axial direction in the conveying direction, or a workpiece that is oriented with the workpiece axial direction perpendicular to the conveying direction. A so-called curve conveyor that gradually changes the horizontal direction is known. However, these also require a large and complicated direction changing device for gradually changing the horizontal direction, and power by a motor or the like is required. In addition, the orientation changed by the orientation changing device may not be stable, and it may be necessary to manually correct the angle.

  The present invention has been made in view of the above-described conventional problems, and with a simple and compact configuration, it is possible to change the horizontal direction of the rod-shaped workpiece during conveyance without applying manual labor or power. The purpose is to provide a workpiece transfer system.

In order to achieve the above object, a workpiece transfer system according to the present invention includes a first conveyor device that conveys a rod-shaped workpiece in a horizontal posture, and a horizontal orientation of the rod-shaped workpiece that receives the rod-shaped workpiece from the first conveyor device.

It is characterized by being.

  Further, in the above configuration, the one side wall and the other side wall of the apparatus main body are formed in a spiral shape continuous around the vertical axis of the workpiece dropping groove.

  Further, in each of the above-described configurations, the second conveyor device includes a conveyance member that places and conveys the rod-shaped workpiece, and a conveyance drive device that travels the conveyance member. Since the plurality of partition members are erected at intervals in the workpiece transfer direction, a storage chamber for storing the bar-shaped workpieces from the workpiece direction changing device one by one between the front and rear adjacent partition members on the transfer member. Is formed.

  Moreover, the said structure WHEREIN: The guide inclined surface which goes down toward the workpiece conveyance direction upstream is formed in the workpiece conveyance direction upstream of the upper surface of the partition member in a 2nd conveyor apparatus.

According to the workpiece transfer system according to the present invention, the workpiece dropping groove portion of the workpiece orientation changing device is disposed in contact with the falling rod-shaped workpiece and guides the rod-shaped workpiece, and is spaced apart from and facing the one sidewall. The other side wall that contacts the work and guides the rod-shaped work is formed, and the one side wall and the other side wall are formed by being twisted around the vertical axis of the work dropping groove, so that it is simple and compact. The horizontal direction of the bar-shaped workpiece can be changed at a relatively high speed. In addition, the work orientation changing device and the entire system can be reduced in space, and no load is applied to the rod-shaped workpiece from the workpiece orientation changing device without the need for power equipment, detection sensors, or operator assistance. There is nothing. Moreover, various take-out modes can be adopted by directly combining the work take-out device and various conveyor devices. In particular, the one-part main body formed by dividing the device main body of the workpiece orientation changing device and the other divided main body are fixed so as to be close to and away from each other, so that the groove width of the workpiece drop groove can be changed according to the outer diameter of the rod-shaped workpiece Therefore, even if it is a rod-shaped workpiece having different outer diameters, the groove width of the workpiece dropping groove can be adjusted appropriately and passed. Therefore, it can be easily switched and transferred to a rod-shaped workpiece having a desired outer diameter.

  Further, in the case where the one side wall and the other side wall of the apparatus main body are formed in a spiral shape that is continuous around the vertical axis of the workpiece dropping groove, the one side wall and the other side wall are in a rod shape due to the spiral shape of the one side wall and the other side wall. It is possible to change the horizontal direction by sliding the work very smoothly and guiding it.

The embodiment described below is merely an example embodying the present invention, and does not limit the technical scope of the present invention. FIG. 1 is a schematic plan view showing a workpiece transfer system according to an embodiment of the present invention. However, the same components as those in the conventional workpiece transfer system shown in FIG. 9 are denoted by the same reference numerals and detailed description thereof may be omitted.
In FIG. 1, a workpiece transfer system 1 according to this embodiment includes a first conveyor device 2 that conveys a rod-shaped workpiece W in a horizontal posture, and a rod-shaped workpiece W that has received and received the rod-shaped workpiece W from the first conveyor device 2. The work direction changing device 3 that changes the horizontal angle θ by 90 degrees and the second conveyor device 4 that carries out the bar-shaped work W discharged from the work direction changing device 3 are configured.

  A skewering device 6 is provided on the upstream side of the first conveyor device 2 in the workpiece conveyance direction (arrow J1 direction). The skewering device 6 includes a piercing device 16 that pierces each Frankfurt E with the skewer F into a skewered product (hereinafter referred to as a rod-shaped workpiece W), an entrance conveyor device 15 that feeds Frankfurt E into the piercing device 16, And a delivery-side conveyor device 17 for feeding the bar-shaped workpiece W from the piercing device 16 to 2. On the upstream side of the skewering device 6 in the workpiece conveying direction, an endless belt 18 (conveying member) for supplying Frankfurt E to the entrance-side conveyor device 15 of the skewering device 6 and a conveying driving device 19 for running the endless belt 18 are provided. A conveyor device 7 is provided.

  On the other hand, the 3rd conveyor apparatus 5 is arrange | positioned in the downstream of the workpiece conveyance direction (arrow J2 direction) of the above-mentioned 2nd conveyor apparatus 4. FIG. The third conveyor device 5 rotates and drives rollers (not shown) spaced apart from the conveyor body 13, an endless belt 14 (conveying member) looped around these rollers, and the rollers. The upper endless belt 14 travels in the direction of the arrow J3. The workpiece traveling direction (arrow J3 direction) of the endless belt 14 is perpendicular to the workpiece conveying direction (arrow J2 direction) of the second conveyor device 4, and parallel to the workpiece conveying direction (arrow J1 direction) of the first conveyor device 2. is there. The endless belt 14 conveys, for example, four workpieces W, W, W, and W at the same time in a state where their rod center directions are directed to the workpiece conveyance direction.

The first conveyor device 2 includes rollers 32 and 32 (see FIG. 6; one is not shown) spaced apart in the horizontal direction, and an endless loop between these rollers 32 and 32. The belt 10 (conveying member) and a conveyance driving device (not shown) that rotationally drives the roller 32 to travel the upper endless belt 10 in the direction of arrow J1.
The workpiece orientation changing device 3 is disposed between the first conveyor device 2 and the second conveyor device 4, receives the rod-shaped workpiece W from the first conveyor device 2, and receives the rod-shaped workpiece W in the horizontal direction. Is changed by an angle θ (in this example, angle θ = 90 degrees) and then transferred to the second conveyor device 4.

  As shown in FIGS. 6 and 7, the second conveyor device 4 includes rollers 33, 33 that are spaced apart in the horizontal direction, and an endless belt 11 that is looped around these rollers 33, 33. (An example of a conveying member according to the present invention) and a conveyance driving device 12 that rotationally drives the roller 33 to travel the upper endless belt 11 in the direction of the arrow J2. On the upper surface of the endless belt 11, plate-like partition members 34, 34, 34,... Are erected at regular intervals in the transport direction (arrow J2 direction). That is, on the endless belt 11, between the partition members 34, 34, storage chambers 35, 35, 35,... For storing the bar-shaped workpieces W released from the lower surface opening 28 of the workpiece orientation changing device 3 one by one. -Is formed. In this case, a guide in which the corner portion of the upper surface 43 of each partition member 34 (see FIG. 7) on the upstream side in the workpiece conveyance direction (opposite to the arrow J2) is cut out, that is, the guide descends in the opposite direction of the arrow J2. The form in which the inclined surface 42 was formed in each partition member 34 is taken. An interval M between the front and rear partition members 34 is set to be somewhat larger than the outer diameter C of the rod-shaped workpiece W. As a result, only one rod-shaped workpiece W can be reliably accommodated in the accommodation chamber 35. Moreover, the space | interval of the upper end position of the guide inclined surface 42 in the front side partition member 34 and the front surface of the rear side partition member 34 is formed widely, and this reception space | interval N is the outer diameter C of the rod-shaped workpiece W, for example. It is set to about 5 times. Thereby, the guide inclined surface 42 having an appropriate inclination angle that can be easily accommodated can be formed. On the other hand, guide members 41A and 41B are attached to the peripheral portions of the lower surface opening 28 on the lower surfaces of the one divided main body 22A and the other divided main body 22B, respectively. These guide members 41A and 41B are formed in an upside down L shape when viewed from the front, and are linear when viewed in the front-rear direction.

  As shown in FIGS. 2 to 4, the work orientation changing device 3 described above has a device main body 21 formed in a block shape, and a workpiece drop formed to communicate with the device main body 21 in the vertical direction to drop the rod-shaped work W. And a groove portion 26. The apparatus main body 21 has a height H, and the workpiece dropping groove 26 has a groove length L. The workpiece dropping groove portion 26 is in contact with one side surface WA of the falling rod-shaped workpiece W and guides the rod-shaped workpiece W downward, and is spaced from the one sidewall 25A while being spaced apart from the one-side wall 25A. And an other side wall 25B that contacts the other side surface WB and guides the rod-shaped workpiece W downward. An upper surface opening 27 is formed on the upper surface 23 of the apparatus main body 21, and a lower surface opening 28 is formed on the lower surface 29. The work dropping groove 26 communicates the upper surface opening 27 and the lower surface opening 28. Thus, the workpiece dropping groove 26 is formed by twisting one side wall 25A and the other side wall 25B of the apparatus main body 21 in a continuous vertical spiral. The shape of the workpiece dropping groove 26 can change the horizontal angle θ of the rod-shaped workpiece W (see FIG. 3B).

  The apparatus main body 21 of the workpiece orientation changing apparatus 3 described above is formed by being divided into one divided main body 22A having one side wall 25A and another divided main body 22B having another side wall 25B. Four female screw holes 24 are provided in the upper surface 23 and the lower surface 29 of the one divided main body 22A and the other divided main body 22B, respectively. These female screw holes 24 are for fixing the work direction changing device 3 to the fixing plate 40 of the system base (not shown) with screws. The one-divided main body 22A and the other divided main body 22B are made of self-lubricating synthetic resin, for example, Duracon (trademark) which is a copolymer containing formaldehyde units and oxyethylene units of polyacetal. Note that the outer peripheral positions α, β, γ, and δ of the apparatus main body 21 shown in plan in FIG. 3B correspond to the outer peripheral positions α, β, γ, and δ in the developed view shown in FIG. doing.

Further, two female screw holes 30 are formed on the upper and lower sides of the other divided main body 22B from the outer peripheral surface of the other divided main body 22B toward the vertical axis K. Male screw members 38, 38 that are rotatably disposed on the system base are screwed into these female screw holes 30, 30. As the male screw member 38 is screwed into the female screw hole 30, the other divided main body 22 </ b> B approaches and separates from the one divided main body 22 </ b> A, and as a result, the groove width D of the workpiece dropping groove 26 is made variable. It has become. After the groove width D is determined to be a desired width, a fixing bolt 37 for fixing to the fixing plate 40 is screwed into the female screw hole 24 of the upper surface 23, so that the other divided main body 22B is divided into one part. Fixed to the main body 22A. That is, the configuration including the female screw hole 30, the male screw member 38, the female screw hole 24, and the fixing bolt 37 constitutes the groove width variable mechanism 39 of the present embodiment.
A guide plate 36 (see FIG. 6) having an upper portion curved in an arc shape is attached to a position in the vicinity of the upper edge portion of the other side wall 25B of the upper surface 23 of the other divided main body 22B of the apparatus main body 21. . This guide plate 36 is for guiding a plurality of bar-shaped workpieces W, W, W,... Coming from the first conveyor device 2 to the upper surface opening 27 of the workpiece orientation changing device 3. That is, the gap between the curved inner peripheral surface of the guide plate 36 and the endless belt 10 at the position wound around the roller 32 of the first conveyor device 2 is set to be slightly larger than the outer diameter C of the rod-shaped workpiece W. .

  Next, the operation of the workpiece transfer system 1 configured as described above will be described. In this case, Frankfurt E was tested, for example, with outer diameters C = 21 mm, 25 mm, 26 mm, and 30 mm. When transporting Frankfurt E having a different outer diameter C, the male screw member 38, which is loosened by loosening the fixing bolt 37 of the variable lateral width mechanism 39, is rotated to advance in the female screw hole 30; The other divided main body 22B is moved closer to and away from the one divided main body 22A to adjust the groove width D of the workpiece dropping groove portion 26 (upper surface opening 27).

  First, a large number of Frankfurts E, E, E,... Are placed and transported on the endless belt 18 of the conveyor device 7 in a horizontal posture in which the work axis is perpendicular to the transport direction. These Frankfurts E, E, E,... Are sequentially transferred to the entrance conveyor device 15 of the skewering device 6 and carried into the piercing device 16. In the piercing device 16, the skewers F are pierced one by one in each Frankfurt E to form a bar-shaped workpiece W, and then are carried out by the delivery-side conveyor device 17. Subsequently, the bar-shaped workpiece W from the delivery-side conveyor device 17 is transferred onto the endless belt 10 of the first conveyor device 2 and conveyed (in the direction of arrow J1). Then, the rod-like workpieces W, W, W,... On the endless belt 10 are guided by the inner wall surface of the guide plate 36 and supplied one by one to the upper surface opening 27 of the apparatus main body 21 of the workpiece orientation changing device 3. The

  In the workpiece orientation changing device 3, the other side surface WB of the bar-shaped workpiece W is in contact with the upper part of the other side wall 25B of the other divided main body 22B, and the one side surface WA is in contact with the upper part of the one side wall 25A of the one divided main body 22A. Thereafter, the bar-shaped workpiece W enters the workpiece dropping groove 26 from the upper surface opening 27, and descends while sliding on the other side wall 25B of the other divided main body 22B and the one side wall 25A of the one divided main body 22A, and the horizontal direction is changed. To go. Then, at the lowest part of the workpiece orientation changing device 3, the rod-shaped workpiece W has its workpiece axial center parallel to the workpiece conveyance direction (arrow J1 direction) of the first conveyor device 2 (that is, the workpiece conveyance direction of the second conveyor device 4). The angle θ = 90) with respect to (in the direction of arrow J2), and the material is sequentially discharged from the lower surface opening 28 of the workpiece dropping groove 26.

  The rod-like workpieces W released from the workpiece orientation changing device 3 are accommodated one by one in the accommodation chamber 35 on the endless belt 11 of the second conveyor device 4 and conveyed in the direction of arrow J2. The state change at this time is shown in FIGS. First, in FIG. 7A, a first bar-shaped workpiece W (1) is stored in a certain storage chamber 35, and the second bar-shaped workpiece W (2) is placed on the bar-shaped workpiece W (1). It is listed. Further, the rod-shaped workpieces W (3) and W (4) are placed on the rod-shaped workpiece W (2) and stand by in the guide members 41A and 41B. Then, when the endless belt 11 slightly advances in the direction of the arrow J2, as shown in FIG. 5B, the rod-shaped workpiece W (2) is moved from the rod-shaped workpiece W (1) to the upper surface 43 of the subsequent partition member 34. Change to. Further, when the endless belt 11 advances in the direction of the arrow J2, the bar-shaped workpiece W (2) moves from the upper surface 43 of the partition member 34 onto the guide inclined surface 42 as shown in FIG. Rolls down on top. And in the figure (d), the rod-shaped workpiece W (2) is about to fall from the guide inclined surface. Subsequently, when the endless belt 11 advances in the direction of the arrow J2, as shown in FIG. 5E, the rod-shaped workpiece W (2) falls into the next storage chamber 35 and is stored on the rod-shaped workpiece W (2). The third rod-shaped workpiece W (3), the fourth rod-shaped workpiece W (4), and the fifth rod-shaped workpiece W (5) in the above slide together in the guide members 41A and 41B. In this way, the rod-shaped workpiece W is guided by the guide inclined surface 42 of the partition member 34 and is transferred after being securely stored in the storage chamber 35 one by one.

  In the above description, an example in which the guide members 41A and 41B are used in order to increase the reliability of workpiece delivery has been described. However, the present invention includes the guide members 41A and 41B omitted. Even with such an omission configuration, the rod-like workpieces W from the lower surface opening 28 of the apparatus main body 21 can be accommodated one by one in the accommodation chamber 35 of the second conveyor device 4. In that case, it is desirable to arrange the work direction changing device 3 as close as possible to the second conveyor device 4 as long as the second conveyor device 4 and the work direction changing device 3 do not interfere with each other.

  And the rod-like workpieces W, W, W,... From the second conveyor device 4 are placed on the endless belt 14 of the third conveyor device 5, for example, four by four. It is conveyed in the direction of arrow J3 perpendicular to the workpiece conveyance direction (arrow J2 direction). In this case, the workpiece axial directions of the four rod-like workpieces W, W, W, W are the same as the workpiece conveying direction (arrow J3 direction). The rod-like workpieces W, W, W, W having such an orientation are boxed in the subsequent process.

  As described above, according to the workpiece transfer system 1 of this embodiment, a simple and compact configuration such as the device main body 21 having the workpiece dropping groove 26 is sufficient, so that not only the workpiece orientation changing device 3 but also the entire system can be reduced in space. Even with such a simple configuration, the horizontal direction of the bar-shaped workpiece W can be reliably changed at a relatively high speed. Further, no power device, detection sensor, or operator assistance is required, and the load applied to the bar-shaped workpiece W from the workpiece orientation changing device 3 is small and does not receive an impact. Moreover, various take-out modes can be adopted by directly combining the entrance-side or exit-side conveyor device with the workpiece take-out device 3. That is, in the workpiece transfer system 1 of this embodiment, since the workpiece conveyance direction J1 from the skewering device 6 to the first conveyor device 2 and the workpiece conveyance direction from the second conveyor device 4a to the packaging device are the same, Since it can move substantially linearly between the skewering device 6 and the broadcasting device, various operations can be performed efficiently.

  Since the one side wall 25A and the other side wall 25B of the apparatus main body 21 are formed in a spiral shape continuous around the vertical axis K of the workpiece dropping groove 26, the spiral shape of the one side wall 25A and the other side wall 25B The one side wall 25A and the other side wall 25B can guide the bar-shaped workpiece W very smoothly and change the horizontal angle θ. Therefore, even in a state where a plurality of bar-shaped workpieces W come to the workpiece drop groove 26, the horizontal angle θ can be changed without any problem with respect to the individual bar-shaped workpieces W. Furthermore, since the one divided main body 22A and the other divided main body 22B are fixed so as to be able to approach and separate from each other, the groove width D of the workpiece dropping groove 26 is made variable according to the outer diameter C of the rod-shaped workpiece W. be able to. Therefore, even if it is the rod-shaped workpiece | work W of different outer diameter C, the rod-shaped workpiece | work W can be passed through the workpiece | work drop groove part 26 adjusted to the appropriate groove width D which can pass a workpiece | work. Accordingly, the workpiece orientation changing device 3 can be easily switched to the rod-like workpiece W having the desired outer diameter C and transferred.

  In addition, the second conveyor device 4 includes an endless belt 11 for conveying a workpiece (an example of a conveying member), and a plurality of partition members 34, 34, 34,. .., And a guide inclined surface 42 is provided at a corner on the rear side of the upper surface 43 of each partition member 34. Since it is formed, the rod-like workpieces W from the workpiece orientation changing device 3 can be smoothly and quickly accommodated in each accommodation chamber 35 one by one. Therefore, even if the plurality of rod-shaped workpieces W come from the workpiece orientation changing device 3, it is not necessary to perform a process of separating them one by one, and the individual rod-shaped workpieces W can be reliably carried out at high speed. Moreover, since the apparatus main body 21 of the workpiece orientation changing apparatus 3 is made of Duracon, which is a self-lubricating synthetic resin, the one side wall 25A and the other side wall 25B are easily slipped. Accordingly, it is possible to change the horizontal angle θ by more smoothly guiding the rod-like workpiece W in sliding contact with the workpiece drop groove portion 3.

Instead of the second conveyor device 4, another second conveyor device 4 a having an endless belt 31 whose work conveyance direction is parallel to the arrow J <b> 1 as shown by a one-dot chain line in FIG. 1 may be provided. I do not care. Also in this case, since the workpiece conveyance direction J1 from the skewering device 6 to the first conveyor device 2 and the workpiece conveyance direction from the second conveyor device 4a to the packaging device are the same, the movement of the operator is linear and the work is performed. Increases efficiency .

Further, in each of the above embodiments, the apparatus main body 21 formed in a block shape is illustrated, but the present invention is not limited thereto. For example, as shown in FIG. 8 (a) ~ (d) , a work orientation changing unit 3b formed in the frame-shaped device body 21b using a first divided body 22Aa and other split body 22Ba are two rod-like member, It is included in the present invention. In the workpiece orientation changing device 3b, the upper end of the right divided main body 22Aa and the upper end of the left other divided main body 22Ba are spaced apart from each other about the vertical axis K. Then, the one divided main body 22Aa is arranged to be inclined slightly downward toward the workpiece conveying direction (arrow J1 direction) of the first conveyor device 2, and the other divided main body 22Ba is arranged to be inclined somewhat upward. Further, with the vertical axis K as the center, the one-divided main body 22Aa and the other-divided main body 22Ba are arranged so as to be inclined inwardly to some extent. With this configuration, the workpiece dropping groove portion 26 twisted around the vertical axis K is formed. The workpiece dropping groove 26 in FIG. 8 is formed to have a groove length A and a groove width B.

  In this workpiece orientation changing device 3b, the left end portion of the rod-like workpiece W whose workpiece axis is perpendicular to the workpiece conveyance direction (arrow J1 direction) in the first conveyor device 2 passes above the upper end of the one-divided main body 22Aa. The right end portion of the rod-shaped workpiece W comes into contact with the upper portion of the other side wall 25Ba of the other divided main body 22Ba. Thereafter, the bar-shaped workpiece W descends in the workpiece drop groove portion 26 while sliding on the other side wall 25Ba of the other divided main body 22Ba and the one side wall 25Aa of the one divided main body 22Aa, and changes its horizontal direction. Then, at the lowest part of the workpiece orientation changing device 3b, the rod-shaped workpiece W has a workpiece axis that is parallel to the workpiece conveyance direction (arrow J1 direction) of the first conveyor device 2 (that is, the workpiece conveyance direction of the second conveyor device 4).
