Description

  The present invention relates to a cloth transfer device in a cloth input machine that inputs cloth in an unfolded state to an input conveyor at a front input position.

  In the so-called linen supply industry, there is a work process in which washed cloths are unfolded and put into a dressed state and put into a dosing machine. The loading machine is equipped with a deployment loading mechanism that has the function of unfolding and loading the cloth. For example, a cloth loading machine that handles large-sized cloth such as sheets can be easily reached by the operator. The cloth can be transported from the work position for attaching the cloth set in this range to the input position for inputting the cloth to the input conveyor. This is because the input position needs to be set higher than the length of the sheet, and therefore the cloth cannot be directly transferred from the work position to the input position, and the cloth needs to be transferred halfway. There are several types of such deployment input mechanisms, and various technical proposals have been made as described below.

  In the case of the present applicant, there is a cloth input device according to Japanese Patent No. 3150934 (Japanese Patent Application Laid-Open No. 11-192400), thereby facilitating the operation and making the input operation in a fixed manner regardless of the operator's ability It can be performed. In this cloth throwing device, the first retainer vertical movement mechanism provided so that the front of the throwing conveyor is used as a cloth unfolding position, moved from the work position to the delivery position, and returned to the work position is provided. The arrangement is arranged on the left and right with respect to the loading conveyor. As long as this arrangement is taken, there is a restriction that the vertical movement mechanism of the first holder and the second holder that waits at the transfer position for the movement of the first holder cannot move the left and right positions of the input conveyor. . This type has a problem that the width of the charging machine is required to be a size obtained by adding installation space such as a vertical movement mechanism of the first retainer to both the left and right sides of the charging conveyor. If the cloth delivery device is arranged not only on the left and right sides of the loading conveyor but also in the center, a loading device having three loading portions can be formed. With the above-mentioned type of charging machine in which a moving mechanism or the like is installed, it is impossible to change the design to a mold having three charging parts.

  In addition, as can be seen in JP-A-11-192399 and JP-A-2006-149491, when the retainer is not a non-circular type but a simple reciprocating type, it can be arranged on the front surface of the input conveyor. There is an advantage that the charging machine can be configured in a continuous type or a multiple type more than that. However, since only one retainer can be provided in one vertical movement mechanism, and the next cloth is attached after the retainer is returned, the cloth can be supplied efficiently. There is a problem that it is difficult.

JP-A-11-192400 JP-A-11-192399 JP 2006-149491 A

  The present invention has been made paying attention to the above-mentioned points, and the problem is that the first retainer in the transfer position is provided in a revolving manner by providing a first retainer that conveys the cloth from the work position to the transfer position. In the cloth throwing machine in which the next cloth can be attached without waiting for the return of the machine, the filling machine can be configured without increasing the size of the apparatus. Moreover, the other subject of this invention is providing the cloth delivery apparatus in the cloth throwing machine which can supply cloth efficiently.

In order to solve the above-described problems, the present invention attaches the cloth by the operator at the working position in order to load the cloth in the unfolded state at the loading position at the front of the loading conveyor. Waiting for the first holder comprising a pair of left and right members for conveying the cloth from the height of the working position to the height of the delivery position, and the cloth conveyed by the first holder at the delivery position; A second holding element comprising a pair of left and right members for conveying the received cloth to the loading position, and a cloth having a guide mechanism for moving the second holding element to the loading position and returning the cloth to the delivery position by unfolding the cloth. In the machine
The first retainer is moved between the work position for attaching the cloth and the delivery position, and the cloth is delivered when the first retainer moves on the inner side close to the input conveyor. In order for the first retainer to move and return to the working position, a revolving mechanism is arranged at the front part of the input conveyor, and a plurality of first retainers are mounted on the revolving mechanism at intervals. It is a thing.

  The cloth delivery device of the present invention attaches the cloth at the work position by the operator in order to load the cloth in the unfolded state at the front loading position on the loading conveyor. A first holder made of a pair of left and right members that conveys the cloth from the height of the position to the height of the delivery position, and the cloth that is conveyed by the first holder at the delivery position and waits for the cloth received A second retainer comprising a pair of left and right members for transporting the fabric to the loading position, and a guide mechanism for moving the second retainer to the loading position to allow the fabric to be unfolded and loaded and to return to the delivery position Applicable to cloth feeders.

  Further, the cloth delivery device of the present invention includes a first holder composed of a pair of left and right members that conveys the cloth from the height of the work position to the height of the delivery position, between the work position and the delivery position. In the point of moving in a revolving manner, it is the same as the invention of the above-mentioned Japanese Patent No. 3150934. However, the present invention does not increase the width of the entire charging machine, and allows the cloth to be efficiently supplied by moving the first retainer in a circular manner. A plurality of first retainers that circulate between the position and the delivery position are arranged, and when the first retainer moves on the inner side near the input conveyor, the cloth is transferred, and the outer side far from the input conveyor is disposed. In order to move the first retainer and return to the working position, a means is provided in which a circulating mechanism with the first retainer is arranged at the front of the input conveyor.

  The cloth delivery device having the above-mentioned circulation mechanism is integrally attached to the body of the cloth feeding machine, and can be arranged at an arbitrary position on the front side of the feeding conveyor, and simplification of the apparatus is also achieved. In this case, the position where the turning mechanism is attached may be anywhere as long as it is on the front side of the machine body.

  The circling mechanism includes a rotating wheel disposed on the work position side and a delivery position side, a rotating rope that is circulated by the rotating wheel, a bracket having a first retainer attached to the rotating rope, and a first attached to the bracket. In order to guide the movement of the one retainer, it is desirable to include guide means arranged along the circulation path of the first retainer. A combination of sprocket and chain, or a combination of toothed pulley and cogged belt can be used as the rotating wheel and rotating rope. When this occurs, the first retainer may swing. Therefore, the first retainer shall be guided by the guide means to guarantee a stable operation that does not cause swinging, etc., and to be connected to a rotating cable such as a chain using a bracket to eliminate the above-mentioned concerns. It is.

  The first holding member composed of a pair of left and right members is connected by a connecting member, and has a guide wheel that moves while rotating in contact with the guide rail of the guide means. Is desired for a safe move. A more stable movement of the first retainer is also ensured by the configuration in which the guide wheels made of a pair of left and right members move while rotating along the guide rails.

  In order to hold the cloth on the second holder while holding the cloth by the first holder, and then release the holding of the cloth by the first holder, the release provided on the first holder A release dog that engages with the lever may be provided in the revolving mechanism. When the cloth held by the first holding element reaches the delivery position, the moving cloth is transferred to the second holding element by the holding force of the first holding element. Nevertheless, the holding by the first holding element is not performed. If it is continued, there is a risk of applying unnecessary external force to the fabric and damaging it. Therefore, when the delivery is completed, the holding of the fabric by the first retainer is released and the risk of damage or the like is eliminated. .

  Since the present invention is configured and operates as described above, the first retainer at the delivery position is returned by providing the first retainer for conveying the cloth from the work position to the delivery position in a circular manner. It is a cloth throwing machine that can continuously attach the cloth without waiting for the next cloth to be attached. Cloths can be thrown in. Therefore, according to the present invention, there is an effect that it is possible to provide a cloth delivery device in a cloth feeding machine that can efficiently supply cloth.
