Description

  The present invention relates to a bulk feeder that aligns parts accommodated in a loose state in a predetermined direction and conveys the aligned parts in an aligned state, and in particular, can accommodate a large number of parts in the bulk feeder in the bulk feeder. It relates to a component storage case.

  A component feeder called a bulk feeder includes a component storage case having a component storage chamber capable of storing a large number of components (mainly electronic components) in a loose state, and a component stored in a bulk state in the component storage chamber. It includes at least a component aligning mechanism that can align in a predetermined direction and a component transport path that can transport the aligned components in an aligned state.

  A component replenishment case CC (see Patent Document 1) shown in FIG. 1A is generally used for replenishing components to the component storage case of the bulk feeder. The component replenishment case CC includes a case body CCa, a connection part CCb, and an opening / closing part CCc. The case main body CCa is formed in a substantially rectangular parallelepiped shape, and has a housing space CCa1 in which a large number of components EC are housed in a loose state. The connection part CCb is formed integrally with the case body CCa at the lower end of the case body CCa, has a connection port CCb1 communicating with the storage space CCa1, and is used when connected to the component storage case. A straight protrusion CCb2 is provided on the outer surface. The opening / closing part CCc integrally has a flexible shutter CCc1 for opening and closing the connection port CCb1 of the connection part CCb.

  When refilling parts into the parts storage case of the bulk feeder using this parts replenishment case CC, the parts replenishment case CC is made into a parts storage case so that the connection port CCb1 of the connection part CCb matches the parts replenishment port of the parts storage case. After the attachment, the opening / closing part CCc is moved with a fingertip to open the connection port CCb1 closed by the shutter CCc1. As a result, the component EC in the storage space CCa1 falls by its own weight into the component storage chamber through the connection port CCb1 and the component supply port, and the desired replenishment is performed.

  By the way, the request from environmental preservation and cost savings, which have been regarded as important in recent years, is a trigger, and a proposal to replace the parts replenishment case CC, which is a plastic rigid material, with another that is easy to dispose of, manufacture, etc. Has been made.

  FIG. 1B shows a component replenishment bag CB showing an example of this proposal. The component replenishment bag CB has a substantially rectangular side surface formed from a film such as a laminate film, and is sealed on two to four sides. It has a portion CBa and has an accommodating space CBb in which a large number of components EC are accommodated in a loose state. The reason why the seal area CBa1 in the lower right corner in the drawing is larger than the others is that the opening position can be visually recognized or the opening opening is made smaller.

  When using the parts replenishing bag CB to refill parts into the parts storage case of the bulk feeder, the lower end of the parts replenishing bag CB is cut off with a scissors or the like, and then the opening matches the parts replenishing opening of the parts storage case. Thus, the parts replenishment bag CB is displaced so as to perform alignment. As a result, the component EC in the storage space CBb falls by its own weight into the component storage chamber through the opening and the component replenishment port, and the desired replenishment is performed.

However, in the case of the component replenishment bag CB, when the component EC is replenished, the opening operation and the alignment operation as described above are required. There is a risk of spilling parts EC outside.

  First, the structure of the component storage case will be described with reference to FIGS. The component storage case 10 includes a main body block 11, a cover block 12, a bag cutting blade 13, and an opening / closing lid 14.

  The main body block 11 includes a component storage chamber 11a, a connection recess 11b, and a guide recess 11c.

  The component storage chamber 11a has a hexagonal front profile, a predetermined front-rear dimension, and a volume for storing a large number of components EC. Further, the upper end of the component storage chamber 11a is opened at the upper surface of the main body block 11 (hereinafter referred to as upper end opening 11a1), and the lower end is opened at the upper surface of the connection recess 11b (hereinafter referred to as lower end opening 11a2).

  The connection recess 11b has a rectangular front profile and a front-rear dimension that matches the front-rear dimension of the main body block 11. The connection recess 11b is used when a component alignment mechanism (not shown) is fitted and connected, and the component alignment mechanism fitted and connected to the connection recess 11b is connected to the component from the lower end opening 11a2 of the component storage chamber 11a. EC is sent.

  The guide recess 11 c is formed of a substantially rectangular parallelepiped recess and is formed on the upper right side of the main body block 11 so as to open at the front surface, the right surface, and the upper surface of the main body block 11. The inner surface (without reference numeral) of the guide recess 11c is preferably a curved surface as shown in FIG.

  Incidentally, the inner side surface (without reference numeral) of the guide recess 11c serves as a remaining piece moving guide that can separate the unsealed residue CBd cut by the bag cutting blade 13 during the refilling operation described later from the unsealing port CBc. Further, the bottom surface 11c1 of the guide recess 11c serves as a support surface that supports the lower end of the component supply bag CB during a replenishment operation described later (hereinafter, the bottom surface 11c1 is referred to as a support surface 11c1).

  The lower surface of the cover block 12 has the same front-rear dimensions and left-right dimensions as the front-rear dimensions and the left-right dimensions of the upper surface of the main body block 11, and is screwed so that the lower surface matches the upper surface of the main body block 11 It is fixed by. The cover block 12 includes a linear recess 12a, a component replenishing port 12b, and a slit 12c.

  The linear recess 12a is formed of a recess having a predetermined front-rear dimension and a vertical dimension. This linear recess 12a is for slidably disposing the open / close lid 14 in the left-right direction, and linear grooves 12a1 are formed on the inner surfaces facing the front and rear of the linear recess 12a.

  The component replenishing port 12b is a hole having a rectangular cross section and a predetermined vertical dimension, and communicates with the component storage chamber 11a. In the illustrated example, the front-rear dimension of the component replenishing port 12b matches the front-rear dimension of the linear recess 12a, and the right side of the component replenishing port 12b matches the right side of the component storage chamber 11a.

  The slit 12c is formed at the center in the front-rear direction on the right side of the bottom surface of the linear recess 12a, with the right end opened to the outside and the left end opened to the component replenishing port 12b. The vertical dimension of the slit 12c is the same as the vertical dimension of the component replenishing port 12b. Further, the width (front-rear dimension) of the slit 12c is slightly larger than the thickness of the component replenishing bag CB (this thickness indicates the thickness of the bag only). Furthermore, an insertion guide surface 12c1 made of a curved surface or a slope for guiding the insertion of the component replenishing bag CB is formed at the right end of the slit 12c.

  Incidentally, the left surface 12b1 of the component replenishing port 12b serves as a movement restricting portion that restricts the movement of the component replenishing bag CB during replenishment work described later (hereinafter, the left surface 12b1 is referred to as a movement restricting portion 12b1). Further, the slit 12c and the support surface 11c1 serve as a bag moving guide that can move the component replenishing bag CB leftward while maintaining a predetermined posture during refilling operations to be described later.

  The bag cutting blade 13 has a cutting edge at the right edge, and is fixed to the upper surface of the main body block 11 by screws or the like so that the cutting edge protrudes into the guide recess 11c. When the bag cutting blade 13 is fixed to the upper surface of the main body block 11, a concave portion having the same front and rear dimensions and depth as the front and rear dimensions and thickness of the bag cutting blade 13 is formed on the upper surface of the main body block 11, and The bag cutting blade 13 is fitted and then fixed by screwing or the like so that the upper surface of the bag cutting blade 13 and the upper surface of the main body block 11 are flush with each other. The distance Dc (see FIG. 4) between the cutting edge of the bag cutting blade 13 and the support surface 11c1 is the remaining opening when the lower end portion of the component replenishing bag CB is cut and opened by the bag cutting blade 13 during the refilling operation described later. The vertical dimension is CBd (see FIGS. 10 and 11).

  The open / close lid 14 has a front-rear dimension that substantially matches the front-rear dimension of the linear recess 12a, and a left-right dimension that simultaneously covers both the component replenishment port 12b and the slit 12c. Further, on the front and rear surfaces of the opening / closing lid 14, linear protrusions 14 a that are movably fitted in the linear grooves 12 a 1 of the linear recesses 12 a are formed. The opening / closing lid 14 is disposed in the linear recess 12a so as to be movable in the left-right direction with the linear protrusion 14a fitted in the linear groove 12a1.

  In the first embodiment, the bag movement guide (slit 12c and support surface 11c1), the bag cutting blade 13, the component replenishing port 12b, the remaining piece movement guide (the inner surface of the guide recess 11c), and the movement described above. The “bag opening means” as defined in the claims is constituted by the restriction portion 12b1.

  Next, the component replenishment operation will be described with reference to FIGS. At the time of replenishment, the parts replenishment bag CB shown in FIG. 1B is turned upside down to collect the parts EC in the accommodation space CBb downward, and the upper end where the parts EC do not exist is pressed with a fingertip (FIG. 8). The symbol HP, hereinafter referred to as a pressing portion HP), the component replenishment bag CB is reversed and returned to its original posture. Even if the component refill bag CB is inverted and returned to its original posture, the component EC in the accommodation space CBb does not move by its own weight below the pressing portion HP.

  Then, as shown in FIGS. 8 and 9, after opening and closing the lid 14 to the left to open the component replenishing port 12b and the slit 12c, the fingertips are kept away from the pressing portion HP of the component replenishing bag CB. The left edge of the lower end portion of the component supply bag CB is inserted into the slit 12c and the lower end of the component supply bag CB is brought into contact with the support surface 11c1.

  Then, as shown in FIGS. 10 and 11, the component replenishment bag CB inserted into the slit 12c is moved leftward with its lower end supported by the support surface 11c1, and the left edge of the lower end of the component replenishment bag CB Is brought into contact with the movement restriction portion 12b1 of the component replenishing port 12b.

  In the process of moving the component refill bag CB in the left direction, the lower end portion of the component refill bag CB is cut by the bag cutting blade 13 to form an opening CBc, and the unsealing residue CBd cut by the bag cutting blade 13 is formed. Is guided to the front side by the remaining piece movement guide (the inner surface of the guide recess 11c) so as to be separated from the opening CBc. The opening CBc formed by the bag cutting blade 13 is refilled when the left edge of the lower end of the component replenishing bag CB contacts the movement restricting portion 12b1 of the component replenishing port 12b, in other words, when the bag is opened to the largest extent. Matches the mouth 12b.

  Then, as shown in FIG. 12, the fingertip is released from the pressing portion HP of the component replenishing bag CB. Since the opening CBc formed by the bag cutting blade 13 is easily opened by its own elasticity and the weight of the component EC (see FIG. 11), the component EC in the housing space CBb of the component refill bag CB is stored in the component from the opening CBc. The dead weight falls into the chamber 11a.

  If the component EC does not adhere to the inner surface of the storage space CBb due to static electricity or the like, all the components EC in the storage space CBb can be dropped by their own weight into the component storage chamber 11a by the above operation. Even if a small amount of the component EC remains in the storage space CBb, the remaining component EC can be easily dropped into the component storage chamber 11a by tapping the component refill bag CB with a fingertip.

  After the replenishment is completed, the empty parts replenishment bag CB is removed, and then the opening / closing lid 14 is moved rightward to close the opening / closing lid 14 parts replenishing port 12b and the slit 12c. As described above, since the unsealing residue CBd when forming the unsealing opening CBc is not separated from the parts replenishing bag CB, when the empty parts refilling bag CB is removed after replenishment, the unsealing residue CBd is removed together. And the unsealed piece CBd can be discarded together with the empty parts replenishment bag CB.

As described above, according to the component storage case 10 described above, at least the following effects (1) to (5) can be obtained.
(1) A part opening case that opens the part replenishing bag CB containing a large number of parts EC and allows the part EC that falls by its own weight from the opening CBc to be introduced into the parts storage chamber 11a. 10, when the component EC is replenished to the component storage case 10 of the bulk feeder using the component replenishment bag CB, the lower end portion of the component replenishment bag CB is moved with a scissors or the like as before. After cutting and opening, there is no need to position the component replenishing bag CB so that the opening is aligned with the component replenishing port of the component storage case. In short, since the intended replenishment operation can be performed easily and accurately by using the bag opening means provided in the component storage case 10 itself, the component EC in the component replenishment bag CB is brought outside during the replenishment operation. It is possible to reliably avoid spilling.
(2) The bag opening means uses a bag movement guide (slit 12c and support surface 11c1) that allows the component replenishment bag CB to move in a predetermined direction with a predetermined posture, and a component replenishment bag using the bag movement guide. In the process of moving the CB in a predetermined direction, the bag cutting blade 13 that can be opened by cutting the lower end of the component refill bag CB, and the opening CBc formed by the bag cutting blade 13 move the component refill bag CB in a predetermined direction. Since it is provided with at least a component replenishing port 12b that can be inserted, the opening operation described above can be performed only by moving the component replenishing bag CB inserted into the slit 12c in a predetermined direction with its lower end supported by the support surface 11c1. In addition, the alignment operation can be performed very easily. Moreover, since the opening CBc formed by the bag cutting blade 13 enters the component replenishment port 12b as the parts refill bag CB moves in a predetermined direction, the component EC that falls by its own weight from the opening CBc It can be reliably guided into the storage chamber 11a.
(3) The bag opening means further includes a remaining piece moving guide (the inner surface of the guide recess 11c) that can separate the unsealed residue CBd cut by the bag cutting blade 13 from the opening CBc. The unsealed opening piece CBd obstructs the weight drop of the component EC from the opening CBc, or the component EC that falls by its own weight from the opening CBc stops and remains on the unsealing residue CBd. There is nothing.
(4) The bag opening means restricts the movement of the component replenishment bag CB by the bag movement guide (slit 12c and support surface 11c1) so that the opening CBc formed by the bag cutting blade 13 matches the component replenishment port 12b. Since the movement restriction part (movement restriction part 12b1 of the parts replenishing port 12b) is further provided, the opening CBc formed by the bag cutting blade 13 is made to coincide with the parts replenishing port 12b when the bag is opened to the maximum, It is possible to smoothly and effectively perform the weight drop of the component EC from the opening CBc into the component storage chamber 11a.
(5) Since the movement restriction part (movement restriction part 12b1 of the parts replenishing port 12b) is present at a position where the unsealed residue CBd cut by the bag cutting blade 13 is not separated from the parts replenishing bag CB, replenishment is completed. When the empty parts refill bag CB is later removed, the unsealed residue CBd can be removed together and the unsealed residue CBd can be discarded together with the empty parts refill bag CB. In short, if the unsealed piece CBd is separated from the component replenishing bag CB, both of them are troublesome to be discarded separately. However, both of them can be easily discarded without causing such trouble.

  In the above description, the bag movement guide (slit 12c and bearing surface 11c1), the bag cutting blade 13, the component replenishing port 12b, the remaining piece movement guide (the inner surface of the guide recess 11c), and the movement restriction portion 12b1 The "bag opening means" is exemplified by the above, but if the "bag opening means" includes at least a bag moving guide, a bag cutting blade 13, and a component replenishing port 12b, the above (1) and (2) The initial purpose can be achieved with the effect of.

  In the process of moving the component refill bag CB to the right, the lower end portion of the component refill bag CB is cut by the bag cutting blade 25 to form the opening CBc, and the unsealing residue CBd cut by the bag cutting blade 25 is formed. Is guided by the remaining piece moving guide (the inner surface of the guide projection 23e) so as to be separated from the opening CBc, and the leading end of the opened remaining piece CBd is led out to the outside from the remaining piece lead-out hole 22b4. In addition, the opening CBc formed by the bag cutting blade 25 is such that the right edge of the lower end portion of the component replenishing bag CB is the movement restriction portion 23c1 of the communication groove 23c of the movable holding piece 23 or the movement restriction of the communication groove 22b2 of the fixed holding piece 22b. When it comes into contact with the portion 22b5, in other words, when it is opened most, it matches the component replenishment port 22a.

  Further, since the opening CBc formed by the bag cutting blade 25 is easily opened by its own elasticity and the weight of the component EC (see FIG. 22), the component EC in the housing space CBb of the component refill bag CB is removed from the opening CBc. It falls by its own weight into the component storage chamber 21a.

  If the component EC is not attached to the inner surface of the storage space CBb due to static electricity or the like, all the components EC in the storage space CBb can be dropped by their own weight into the component storage chamber 21a by the above operation. Even if a small amount of the component EC remains in the accommodation space CBb, the remaining component EC can be easily dropped into the component storage chamber 21a by tapping the component refill bag CB with a fingertip.

  After the replenishment is completed, the empty part replenishment bag CB is removed, and then the opening / closing lid 24 is fitted into the auxiliary replenishment port to close the auxiliary replenishment port and the component replenishment port 22a. As described above, since the unsealing residue CBd when forming the unsealing opening CBc is not separated from the parts replenishing bag CB, when the empty parts refilling bag CB is removed after replenishment, the unsealing residue CBd is removed together. And the unsealed piece CBd can be discarded together with the empty parts replenishment bag CB.

Thus, according to the aforementioned component storage case 20, at least the following effects (1) to (6) can be obtained.
(1) A part opening case that opens the part replenishing bag CB containing a large number of parts EC and allows the part EC that falls by its own weight from the opening CBc to be introduced into the parts storage chamber 21a. 20, when the component EC is replenished to the component storage case 20 of the bulk feeder using the component replenishment bag CB, the lower end portion of the component replenishment bag CB is moved with a scissors or the like as before. After cutting and opening, there is no need to position the component replenishing bag CB so that the opening is aligned with the component replenishing port of the component storage case. In short, since the intended replenishment operation can be performed easily and accurately by using the bag opening means provided in the component storage case 10 itself, the component EC in the component replenishment bag CB is brought outside during the replenishment operation. It is possible to reliably avoid spilling.
(2) The bag opening means includes a bag movement guide (a fixed clamping piece 22b, a movable clamping piece 23 and a support surface 22c) that allows the component replenishment bag CB to move in a predetermined direction while maintaining a predetermined posture, and a bag movement guide. A bag cutting blade 25 that can be opened by cutting the lower end portion of the component replenishing bag CB in the process of moving the component replenishing bag CB in a predetermined direction by using the bag, and an opening CBc formed by the bag cutting blade 25 replenishes the component. Since it has at least a component replenishing port 22a (including an auxiliary replenishing port) that can enter when the bag CB moves in a predetermined direction, the component replenishing bag CB sandwiched between the fixed clamping piece 22b and the movable clamping piece 23 By simply moving the lower end in a predetermined direction while being supported by the support surface 22c, the opening operation and the alignment operation can be performed very easily. In addition, since the opening CBc formed by the bag cutting blade 25 enters the component replenishment port 22a as the parts refill bag CB moves in a predetermined direction, the component EC that falls by its own weight from the opening CBc It can be reliably guided into the storage chamber 21a.
(3) The bag opening means further includes a remaining piece moving guide (inner side surface of the guide projection 23e) that can separate the unsealed residue CBd cut by the bag cutting blade 25 from the opening CBc. The unsealed opening piece CBd obstructs the weight drop of the component EC from the opening CBc, or the component EC that falls by its own weight from the opening CBc stops and remains on the unsealing residue CBd. There is nothing.
(4) The bag opening means is a component using a bag moving guide (fixed clamping piece 22b, movable clamping piece 23 and bearing surface 22c) so that the opening CBc formed by the bag cutting blade 25 matches the component replenishing port 22a. Since it further includes a movement restriction part (movement restriction part 23c1 of the communication groove 23c of the movable holding piece 23 and movement restriction part 22b5 of the communication groove 22b2 of the fixed holding piece 22b) that can restrict the movement of the refill bag CB, the bag. When the opening CBc formed by the cutting blade 25 is opened to the largest extent, it is matched with the component replenishing port 22a, and the weight drop of the component EC from the opening CBc into the component storage chamber 21a is smoothly and effectively performed. Can be done.
(5) The movement restricting portions (the movement restricting portion 23c1 of the communication groove 23c of the movable holding piece 23 and the movement restricting portion 22b5 of the communication groove 22b2 of the fixed holding piece 22b) are unsealed pieces CBd cut by the bag cutting blade 25. Exists in a position where it is not cut off from the parts replenishing bag CB, and when the empty parts replenishing bag CB is removed after replenishment, the unsealed residue CBd can be removed together and the unsealed residue CBd is removed from the empty parts replenishing bag. Can be discarded with CB. In short, if the unsealed piece CBd is separated from the component replenishing bag CB, both of them are troublesome to be discarded separately. However, both of them can be easily discarded without causing such trouble.
(6) Since the bag moving guide includes the movable holding piece 23 and the fixed holding piece 22b capable of holding the lower end portion of the component replenishing bag CB, the lower end portion of the component replenishing bag CB is held between the fixed holding piece 22b. After being sandwiched between the portion 22b3 and the sandwiching portion 23d of the movable sandwiching piece 23, the fingertip can be released from the pressing portion HP of the component replenishing bag CB. In short, in the process of moving the component replenishment bag CB in the right direction, it is not necessary to keep the pressing portion HP of the component replenishment bag CB with the fingertip, so that the operation related to the movement can be easily performed.
