Description

TECHNICAL FIELD The present invention relates to a tray feeder for supplying components by extracting component storage bodies from magazines, and a component mounting apparatus provided with this tray feeder.

Conventionally, there has been known a component mounting apparatus that picks up a supplied component with a mounting head and mounts it on a board. There are various forms of devices for supplying components in such a component mounting apparatus, and one of them is known as a tray feeder. The tray feeder is mainly for supplying large odd-shaped parts, and the parts are supplied in a state of being stored in a parts storage body. The component storage body is composed of a tray having pockets for storing components and a pallet to which the tray is attached.

The tray feeder has a rack portion and a drawer table. A magazine is detachably attached to the rack portion. The magazine is provided with a plurality of slots arranged vertically, and component storage bodies are inserted into the slots. The drawer table moves up and down with respect to the rack portion, and draws out the component storage body inserted in the slot. The pull-out table from which the component container is pulled out is moved to a predetermined component supply height by an elevating mechanism, and the component is supplied to the mounting head.

In such a tray feeder, each slot of the magazine is configured such that both end portions of the component storage body are supported from below by a pair of rails positioned at the same height. Here, if the component storage body is inserted in a diagonal posture with different heights at both ends instead of a horizontal posture, and is inserted across a plurality of slots that are adjacent to each other in the vertical direction, the component storage body is inserted into the slot. It cannot be withdrawn by the withdrawal stage. For this reason, conventionally, rails positioned at the same height are marked with the same mark, and when an operator inserts a component storage body into a slot according to the mark, the component storage body automatically assumes a horizontal posture. (For example, Patent Document 1 below).

WO2005/112535

However, as described above, even if the same mark is attached to a pair of rails positioned at the same height, the operator may not be able to recognize the mark depending on the situation. There could have been cases where the storage body was actually in an oblique posture. If the component storage body is inserted into the slot at an angle, it will not be possible to pull it out even if you try to pull it out. There was a problem.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a tray feeder and a component mounting apparatus capable of preventing stagnation of component mounting work caused by inserting a component container into a slot in an oblique posture.

The carriage 21 is movable on the floor by means of a plurality of wheels 21 a , and the rack portion 22 is attached to the front portion of the carriage 21 . The magazine 23 is detachably attached within the rack portion 22 . The drawer table 24 and the lifting mechanism 25 are provided at the rear portion of the rack portion 22 .

The rack portion 22 is formed in the shape of a box as a whole, and has a magazine mounting portion 31 which is a space penetrating in the Y-axis direction (FIG. 3). Two magazine mounting portions 31 are arranged side by side in the Z-axis direction in the rack portion 22 . A magazine door 32 that covers the front sides of the two magazine mounting portions 31 is provided on the front side (on the operator OP side) of the rack portion 22 so as to be openable and closable.

In FIG. 5A, the magazine 23 has a shape that opens in the Y-axis direction as a whole, and includes left and right side plates 41 , a top plate 42 and a bottom plate 43 . The left and right side plates 41 face each other in the X-axis direction and are connected by a top plate 42 and a bottom plate 43 extending in the X-axis direction. The magazine 23 has a plurality of slots 44 arranged vertically. Each slot 44 supports the component storage body 14 inserted in a horizontal posture from its lower surface side.

In FIG. 5B, the component storage body 14 is composed of a dish-shaped pallet 51 and one or more trays 52 detachably attached to the pallet 51 . The tray 52 is provided with a plurality of pockets 53P arranged in a matrix. The component 3 is stored in each pocket 53P.

5A and 6, each of a plurality of slots 44 provided in the magazine 23 is composed of a pair of rails 45 supporting both ends of the component storage body 14 inserted in a horizontal posture. Therefore, on the inner surfaces of the left and right side plates 41 of the magazine 23, a plurality of rails 45 are arranged in the Z-axis direction. A pair of rails 45 forming one slot 44 are positioned at the same height. Each rail 45 protrudes and extends in the horizontal direction (in the X-axis direction) toward the inside of the magazine 23 from the inner surface of each of the left and right side plates 41 .

As described above, in the present embodiment, each of the plurality of slots 44 of the magazine 23 supports from below by a pair of rails 45 positioned at the same height both ends of the component storage body 14 inserted in a horizontal posture. It is configured.

The magazine 23 is attached to a magazine attachment portion 31 provided in the rack portion 22 . When attaching the magazine 23 to the magazine attachment portion 31, the magazine door 32 is opened and the magazine 23 is horizontally (rearwardly) inserted into the magazine attachment portion 31 from the front side of the rack portion 22 (FIG. 3).

When the magazine 23 in which a plurality of component storage bodies 14 are inserted into the slots 44 is attached to the magazine mounting portion 31, the plurality of component storage bodies 14 in the magazine 23 are set in the rack portion 22 at once. The component storage body 14 can also be set in the rack section 22 by inserting the component storage body 14 into the slot 44 of the magazine 23 attached to the rack section 22 .

When two magazines 23 are attached to the upper and lower magazine attachment portions 31 of the rack portion 22, the number of slots 44 corresponding to the sum of the number of slots 44 of the upper and lower magazines 23 in the rack portion 22 is Z. aligned along the axis. For control of the tray feeder 12, each of the plurality of slots 44 arranged in the rack section 22 is given a serial slot number.

In this embodiment, slot numbers "1", "2", "3", . . . , "n", . be done. The slot 44 of each magazine 23 is also given a local slot number unique to that magazine 23 . The local slot number is indicated on the front end face 41T of each of the left and right side plates 41 of each magazine 23 (FIG. 7; see also FIGS. 5A and 5B for the position of the front end face 41T).

A component container 14 is inserted into each of the plurality of slots 44 of the magazine 23 by the operator OP according to predetermined production data. The production data records the slot number of the slot 44 into which the component storage body 14 is to be inserted and the type of the component 3 to be stored in the component storage body 14 inserted into the slot 44 with that slot number. Accordingly, the operator OP inserts the component container 14 containing the component 3 of the type recorded in the production data into the slot 44 with the slot number recorded in the production data. When the operator OP inserts the component storage body 14 in a horizontal position into the slot 44 with the slot number "n" according to the production data, the left and right ends of the component storage body 14 constitute the slot 44 with the slot number "n". is supported from below by a pair of rails 45.

The distance between the two rails 45 adjacent to each other in the Z-axis direction is smaller than the height of the component storage body 14 (the height from the bottom surface of the pallet 51 to the top surface of the tray 52). Therefore, two component storage bodies 14 cannot be simultaneously inserted into two slots 44 adjacent in the Z-axis direction (that is, two slots 44 having consecutive slot numbers). Therefore, when the component container 14 is inserted into the slot 44 with the slot number "n", the slot 44 with the slot number "n-1" located one step above the slot 44 and the slot located one step below The component container 14 is never inserted into the slot 44 numbered "n+1".

In FIG. 5B, a pair of engaged blocks 54 are provided facing each other in the X-axis direction on the rear end side (the side opposite to the operator OP) of the upper surface of the pallet 51 of the component storage body 14. ing. Concave portions 55 that are recessed from the inside toward the outside in the X-axis direction are provided at the ends of the pair of engaged blocks 54 facing each other.

When the magazine 23 in which a plurality of component storage bodies 14 are inserted is set in the rack portion 22, the rear end portion of each component storage body 14 protrudes rearward from the rack portion 22 (FIG. 8). A pair of engaged blocks 54 of each component storage body 14 also protrude rearward from the rack portion 22 , and the engaged blocks 54 of the plurality of component storage bodies 14 are located in the rear region of the rack portion 22 along the Z axis. They are lined up in the same direction.

In FIG. 4, the drawer table 24 has a box shape with a flat upper surface. An engaging rod 61 extending in the X-axis direction is provided on the upper surface side of the drawer table 24 (see also FIGS. 9A and 9B). The engaging rod 61 moves above the drawer table 24 in the Y-axis direction by the operation of the drawer mechanism 62 built in the drawer table 24 (arrow A shown in FIG. 4).

4, the lifting mechanism 25 includes front and rear guide columns 71 extending upward from the carriage 21, ball screws 72 extending in the Z-axis direction, and a lifting motor rotating the ball screws 72 around the Z-axis. It has 73. The ball screw 72 is screwed into the nut portion 24N provided at the rear portion of the drawer table 24, and the guide column 71 guides the movement of the drawer table 24 in the Z-axis direction. When the lifting motor 73 operates, the ball screw 72 rotates around the Z-axis. When the ball screw 72 rotates, the drawer table 24 moves up and down in the rear region of the rack portion 22 (arrow B shown in FIG. 4).

In FIG. 10 , a control device 80 (see also FIG. 1 ) provided in the component mounting apparatus 1 controls the operation of each section of the component mounting apparatus 1 . Specifically, the control device 80 controls the transport of the board 2 by the transport conveyor 11 and the positioning operation to the work position. The control device 80 also controls the feeding operation of the component 3 by the tray feeder 12 . Specifically, it controls the moving operation of the engagement rod 61 by the drawer mechanism 62 and the elevating operation of the drawer table 24 by the elevating mechanism 25 . The control device 80 also controls the pickup operation of the component 3 by the mounting head 13 and the movement control of the mounting head 13 by the head moving mechanism 13K. The control device 80 has a storage section 80a. The storage unit 80a stores the above-described production data and the like in addition to the mounting program data defining the operation procedure of each unit.

In FIG. 10, a touch panel 81 is connected to the control device 80 . The operator OP makes various inputs to the component mounting apparatus 1 by operating the touch panel 81 . On the other hand, the control device 80 gives various commands to the operator OP through the touch panel 81 and issues various information, warnings, and the like.

When pulling out the component storage body 14 from the slot 44 of the magazine 23 attached to the rack section 22, the control device 80 first operates the lifting motor 73 to open the slot 44 into which the component storage body 14 to be pulled out is inserted. The drawer table 24 is moved to height. When the upper surface of the drawer table 24 is positioned at the height of the slot 44, the drawer mechanism 62 is operated to move the engaging rod 61 forward. Then, the left and right ends 61T of the engaging rod 61 are engaged with the concave portions 55 of the pair of engaged blocks 54 provided in the component storage body 14 (Fig. 11(a) -> Fig. 11(b)).

When the left and right ends 61T of the engaging rod 61 are engaged with the pair of engaged blocks 54, the control device 80 operates the pull-out mechanism 62 to move the engaging rod 61 rearward and pull the parts storage body 14. It is placed on the upper surface of the drawer table 24 (FIG. 11(b)→FIG. 12(a)→FIG. 12(b)). When the pulled-out component storage body 14 is placed on the upper surface of the drawer table 24, the elevating motor 73 is operated to raise the drawer table 24 to the component supply height shown in FIG. When the drawer table 24 is positioned at the component supply height, the component 3 stored in the component storage body 14 can be picked up by the mounting head 13 .

When the component storage body 14 is horizontally inserted into the slot 44 with the slot number "n", the left and right ends of the component storage body 14 are supported by a pair of rails 45 forming the slot 44 with the slot number "n". 13(a). On the other hand, when the component container 14 is inserted into the slot 44 of the slot number "n" not in a horizontal position but in an oblique position in which the heights of the left and right ends are different (vertically adjacent to each other). When inserted across a plurality of slots 44 located), the component storage body 14 has one end supported by the rail 45 forming the slot 44 with the slot number "n" and the other end It is in a state of being supported by the rails 45 forming the slot 44 with the slot number "n-1" (Fig. 13(b)). Alternatively, one end is supported by the rail 45 forming the slot 44 with the slot number "n" and the other end is supported by the rail 45 forming the slot 44 with the slot number "n+1" ( FIG. 13(c)).

As shown in FIG. 13(b) or FIG. 13(c), when the component storage body 14 is inserted into the slot 44 in an oblique posture, the left and right ends 61T of the engaging rod 61 are pushed into the component storage body. 14 cannot be engaged with the engaged block 54 of the pallet 51, and the component storage body 14 cannot be pulled out onto the drawer table 24.例文帳に追加Therefore, when inserting the component storage body 14 into the slot 44, the operator OP needs to be careful so that the component storage body 14 is inserted into the slot 44 in a horizontal posture.

This embodiment is configured to prevent the operator OP from accidentally inserting the component storage body 14 into the slot 44 in an oblique posture. Further, even if the component storage body 14 is inserted into the slot 44 in an oblique posture by mistake, it is configured such that this can be detected before the pull-out mechanism 62 pulls out the component storage body 14 . These configurations will be described below.

In FIG. 7, the plurality of slots 44 provided in the magazine 23 are configured such that the first slots 44a and the second slots 44b are arranged alternately in the vertical direction. Here, the first slot 44a is the slot 44 in which the width W of each of the pair of rails 45 has the first dimension W1. The second slot 44b is a slot 44 in which the width W of each of the pair of rails 45 has a second dimension W2 different from the first dimension W1 (larger than the first dimension W1).

Thus, in this embodiment, the pair of rails 45 forming each of the plurality of slots 44 of the magazine 23 have the same width W, and form another slot 44 located adjacent to each other in the vertical direction. It has a width W different from that of the pair of rails 45 .

Therefore, when inserting the component storage body 14 into the slot 44 of the magazine 23, the operator OP visually checks that the width W of the rail 45 of the slot 44 is the same on the left and right (both ends of the component storage body 14). By checking and further checking by touching the rails 45 with both hands, it is possible to confirm that the two rails 45 are at the same height. Accordingly, it is possible to prevent the operator OP from inserting the component storage body 14 into the slot 44 in an oblique posture by mistake.

As shown in FIG. 7, identification marks 46 having the same identifier are provided near the pair of rails 45 forming the slot 44 (in this case, the front end surfaces 41T of the left and right side plates 41 of the magazine 23). is provided. The identification mark 46 has a different identifier from the identification mark 46 attached in the vicinity of each of the pair of rails 45 constituting the other slot 44 located adjacent in the vertical direction.

The identifier is, for example, a color, and in this embodiment, the color of the identification mark 46 provided corresponding to one slot 44 is the same as the color of the identification mark 46 provided corresponding to the slot 44 on the upper side. , and the color of the identification mark 46 provided corresponding to the slot 44 one step lower. In the present embodiment, a white mark 46a with a white color that is the first color of the identifier and a black mark 46b with a black color that is the second color different from the first color are Z They are arranged alternately in the axial direction.

When the operator OP inserts the component storage body 14 into the slot 44 of the magazine 23, the operator OP visually recognizes the identification mark 46 provided near each of the pair of rails 45 that constitute the slot 44. It can be confirmed that the two rails 45 are positioned at the same height by the fact that (if the identifier is a color, the color is the same) on the left and right. Therefore, it is possible to more reliably prevent the component storage body 14 from being erroneously inserted into the slot 44 in an oblique posture.

4 and 9(a) and (b), sensor mounting arms 91 extending rearward from the left and right ends of the drawer table 24 are provided on the rear end side of the drawer table 24. A detection sensor 92 is attached to each tip (front end) of each sensor attachment arm 91 . Two detection sensors 92 attached to the two sensor attachment arms 91 are positioned facing each other in the X-axis direction. One of these two detection sensors 92 is a light projector 92a and the other is a light receiver 92b.

9(b) and 11(a) and (b), the distance between the light projector 92a and the light receiver 92b is larger than the dimension of the component container 14 (of the pallet 51) in the X-axis direction. The light projector 92a projects the inspection light 93 in the horizontal direction (X-axis direction) toward the light receiver 92b, and when the light receiver 92b receives the inspection light 93, it outputs a light reception signal to the control device 80 (FIG. 10). ).

The control device 80 causes the light projector 92 a to project the inspection light 93 while the drawer table 24 is positioned at the height of the slot 44 . The inspection light 93 projected by the light projector 92a is not blocked by anything when the component storage body 14 is not inserted into the slot 44 at the height of the drawer table 24, so the light receiver 92b (FIG. 9(a)). At this time, the detection sensor 92 is in a "non-detection state" in which the component storage body 14 is not detected. On the other hand, when the component storage body 14 is inserted into the slot 44, the light is blocked by the component storage body 14 inserted in the slot 44, so that the light is not received by the light receiver 92b (FIG. 9(b)). At this time, the detection sensor 92 is in a “detection state” in which the component storage body 14 is detected.

Here, when the inspection light 93 is blocked by the component storage body 14, when the component storage body 14 is in a horizontal position, the engaged block 54 provided in the component storage body 14 (more specifically, the engaged block 54 on the side of the projector 92a) block 54) (FIG. 9(b)). On the other hand, when the posture of the component storage body 14 is oblique, the inspection light 93 is blocked by the upper surface or the lower surface of the component storage body 14 .

As described above, in the present embodiment, the detection sensor 92 determines whether or not the inspection light 93 projected in the horizontal direction is blocked by the component storage body 14 . 14 is detected.

In FIG. 10, the control device 80 has an attitude detection section 80b. Based on the detection information from the detection sensor 92 , the posture detection unit 80 b performs posture check (posture detection) to detect the posture of the component storage body 14 inserted into the slot 44 . Specifically, the posture check is based on whether the detection sensor 92 is in a "non-detection state" or a "detection state" at the timing when the detection sensor 92 is moved up and down and the inspection light 93 is projected. , and the presence or absence of the component storage body 14 at a plurality of heights in a certain region in the vertical direction including the slot 44 .

The attitude check is performed based on the production data stored in the storage unit 80a. to the drawer table 24 (for example, immediately after the component container 14 is inserted into the slot 44). In the posture check (method for detecting the posture of the component storage body 14), the posture detection unit 80b raises and lowers the detection sensor 92 to detect the presence or absence of the component storage body 14 at a plurality of heights in a certain vertical region including the slot 44. After executing the step of checking (inspection step), based on the inspection result (detection information of the detection sensor 92) obtained in the inspection step, the step of determining the orientation of the component storage body 14 inserted in the slot 44 (posture Judgment process) is executed.

When detecting the posture of the component storage body 14 in the slot 44 with the slot number "n", the posture detection unit 80b first operates the lifting mechanism 25 to lift the drawer table 24, and the detection sensor 92 detects the position of the slot number "n". n−1”, “n”, and “n+1” are positioned at the height of each slot 44 (FIG. 14). Then, each time the detection sensor 92 is positioned at the height of each slot 44, the light projector 92a emits the inspection light 93 to change the state of the detection sensor 92 ("detection state" or "non-detection state"). or not) is inspected (inspection process). Here, the vertical regions including the positions of the slots 44 with the slot numbers "n-1", "n", and "n+1" correspond to the fixed vertical regions including the slot "n".

Cases in which the component container 14 is inserted into the slot 44 with the slot number "n" include the following first case, second case, third case, and fourth case. In the first case, as shown in FIGS. 15(a), (b), and (c), the component container 14 is horizontally inserted into the slot 44 with the slot number "n". As shown in FIGS. 16(a), (b), and (c), the second case has one end of the component storage body 14 inserted into the slot 44 with the slot number "n". This is the case where the other end is inserted into slot 44 with slot number "n-1" because body 14 is in an oblique posture.

As shown in FIGS. 17(a), (b), and (c), the third case has one end of the component storage body 14 inserted into the slot 44 with the slot number "n". This is the case where the other end is inserted into slot 44 with slot number "n+1" because body 14 is in an oblique posture. The fourth case is a case in which the component storage body 14 itself is not inserted into the slot 44 with the slot number "n" (a case in which it is neither horizontal nor oblique).

In the first case where the component container 14 is horizontally inserted into the slot 44 with the slot number "n", the inspection light 93 of the detection sensor 92 is not blocked at the position of the slot number "n-1" (FIG. 15). (a)), it is blocked by the component container 14 at the position of the slot number "n" (FIG. 15(b)), and is not blocked at the position of the slot number "n-1" (FIG. 15(c)). In this case, the inspection results obtained in the inspection process are "non-detection", "detection", and "non-detection" in the order of slot numbers "n-1", "n", and "n+1". 1 case” column). Based on this inspection result, the control device 80 determines that the component storage body 14 inserted in the slot 44 with the slot number “n” is in a horizontal posture (posture determination step), and places the component storage body 14 on the drawer table 24 . It is determined that it is possible to withdraw by , and an "OK" flag is set.

In the second case where the component container 14 is inserted obliquely into the slot 44 with the slot number "n", the inspection light 93 of the detection sensor 92 is detected by the component container 14 at the position of the slot number "n-1". (FIG. 16(a)), is blocked by the component storage body 14 at the position of the slot number "n" (FIG. 16(b)), and is not blocked at the position of the slot number "n+1" (FIG. 16(c)). In this case, the inspection results obtained in the inspection process are "detected", "detected", and "not detected" in the order of the slot numbers "n-1", "n", and "n+1" ("second Case” column). Based on this inspection result, the control device 80 determines that the component storage body 14 inserted in the slot 44 with the slot number "n" is in an oblique posture (posture determination step), and places the component storage body 14 on the pull-out table. 24 determines that withdrawal is not possible. Then, an "NG" flag is set, and a predetermined notification is given to the operator OP via the touch panel 81 as notification means (that the component container 14 inserted in the slot 44 with the slot number "n" is in an oblique posture). notification) is performed (notification step).

In the third case where the component container 14 is inserted obliquely into the slot 44 with the slot number "n", the inspection light 93 of the detection sensor 92 is not blocked at the position of the slot number "n-1" (Fig. 17(a)), the position of the slot number "n" is blocked by the component storage body 14 (FIG. 17(b)), and the position of the slot number "n+1" is blocked by the component storage body 14 (FIG. 17(c)). ). In this case, the inspection results obtained in the inspection process are "not detected", "detected", and "detected" in the order of the slot numbers "n-1", "n", and "n+1" ("third slot in FIG. 18"). Case” column). Based on this inspection result, the control device 80 determines that the component storage body 14 inserted in the slot 44 with the slot number "n" is in an oblique posture (posture determination step), and places the component storage body 14 on the pull-out table. 24 determines that withdrawal is not possible. Then, an "NG" flag is set, and a predetermined notification is given to the operator OP via the touch panel 81 (notification that the component container 14 inserted in the slot 44 with the slot number "n" is in an oblique posture). (notification step).

In the fourth case where the component container 14 is not inserted into the slot 44 of the slot number "n" to which it should be inserted, the inspection light 93 of the detection sensor 92 is emitted from the slot numbers "n", "n-1", "n+1". ” is not interrupted by any of the In this case, the inspection results obtained in the inspection process are "non-detection", "non-detection", and "non-detection" in the order of the slot numbers "n-1", "n", and "n+1" (" 4th case” column). Based on the result of this inspection, the controller 80 determines that the component container 14 is not inserted into the slot 44 with the slot number "n" (posture determination step). Then, an "NG" flag is set, and the operator OP is notified via the touch panel 81 (notification that the component container 14 is not inserted in the slot 44 with the slot number "n" (notification step).

As in the first case described above, when it is determined in the posture determination step that the posture of the component storage body 14 in the slot 44 is the horizontal posture, the work of reinserting the component storage body 14 into the slot 44 is omitted. No need. On the other hand, as in the second and third cases, when it is determined in the posture determination step that the posture of the component storage body 14 in the slot 44 is oblique, the component storage body 14 cannot be inserted into the slot 44 . Repair work is required, and the operator OP must pull out the once inserted component storage body 14, place the component storage body 14 in a horizontal posture, and reinsert it. Further, as in the fourth case, when it is determined that the component storage body 14 is not inserted into the slot 44 in the attitude determination step, the operator OP selects the component storage body 14 to be inserted into the slot 44. It must be prepared and inserted into slot 44 .

By checking the posture of the component storage body 14 in this way, even if the operator OP has erroneously inserted the component storage body 14 into the magazine 23 in an oblique posture, this can be detected in advance. Therefore, it is possible to reinsert the component storage body 14, thereby preventing a situation in which the component storage body 14 cannot be pulled out.

The attitude check must be performed at least before the operation of pulling out the component container 14 whose attitude is to be checked from the magazine 23 . As described above, the timing is immediately after the component storage body 14 is inserted into the slot 44 (immediately after a changeover due to the changeover of the model to be produced, or when the component storage body 14 is replaced to switch the type of parts to be supplied). immediately after the case). It is preferable to carry out immediately after the start of production for the component storage bodies 14 that have already been inserted into the slots 44 at the start of production.

The orientation check may be performed for all the slots 44 lined up in the rack section 22, but only for the slots 44 in which it is known that the component storage bodies 14 are inserted based on the production data. may be executed. The former method has the advantage of being able to detect the component container 14 that has been erroneously inserted into the slot 44 that is supposed not to be inserted in the production data. There is an advantage that the takt time can be improved by keeping it at .

In the above example, when detecting the attitude of the component storage body 14 inserted in the slot 44 with the slot number "n", the slot 44 with the slot number "n" and one slot 44 on the upper side are detected. The presence or absence of the component storage body 14 is detected for the slot 44 on the lower side. This is because there is a premise that the component storage body 14 is not inserted into the slot 44 to be inserted. The detection of the posture of the component storage body 14 may be performed at a plurality of heights in a certain area in the vertical direction including the slot 44 of interest. An examination of the body 14 need not be performed. Regarding the slots 44 which may contain the component storage bodies 14 in the upper and lower slots 44, the presence or absence of the component storage bodies 14 at a plurality of heights in a certain area between a little above and a little below the slot 44 is checked. You should investigate.

As described above, in the component mounting apparatus 1 (tray feeder 12) according to the present embodiment, the pair of rails 45 forming each of the plurality of slots 44 of the magazine 23 of the tray feeder 12 have the same width W. However, it has a width W different from that of a pair of rails 45 forming another slot 44 positioned adjacent to it in the vertical direction. Therefore, when inserting the component storage body 14 into the slot 44, the operator OP visually confirms that the width W of the rail 45 of the slot 44 is the same on the left and right (both ends of the component storage body 14). Furthermore, by touching and confirming the rails 45 with both hands, it is possible to confirm that the two rails 45 are at the same height. As a result, it is possible to prevent the operator OP from inserting the component storage body 14 into the slot 44 in an oblique posture. It is possible to prevent the stagnation of the component mounting work that occurs (forcible stop of the operation of the component mounting apparatus 1, etc.).

Although the embodiments of the present invention have been described so far, the present invention is not limited to the above, and various modifications are possible. For example, in the above-described embodiment, the plurality of slots 44 provided in the magazine 23 includes two types of slots 44 (a first slot 44a and a second slot 44) having different widths W of the rails 45 alternately in the vertical direction. However, it is sufficient that the width W of the pair of rails 45 forming each slot 44 is different from the width W of the pair of rails 45 forming the other vertically adjacent slot 44. , three or more slots 44 having different widths W of the rails 45 may be arranged in the vertical direction.

To provide a tray feeder and a component mounting device capable of preventing stagnation of component mounting work caused by inserting a component container into a slot in an oblique posture.
